Purpose: To investigate the effect of sufentanil on anesthesia in patients undergoing cardiovascular surgery. Methods: The subjects comprised a total of 100 patients who were scheduled to undergo cardiovascular surgery in Taikang Tongji (Wuhan) Hospital from January 2021 to December 2021 and met the inclusion criteria. The eligible patients were assigned in a ratio of 1:1 to receive either remifentanil (control group) or sufentanil (study group) during cardiovascular surgery, with 50 patients in each group. The anesthetic effect of remifentanil and sufentanil was compared. Results: Patients treated with sufentanil experienced a faster onset of anesthesia and a shorter time-lapse before extubation, postoperative spontaneous breathing recovery, and postoperative anesthesia recovery when compared with those administered with remifentanil (p < 0.05). Sufentanil provided more potent pain mitigation for patients undergoing cardiovascular surgery than remifentanil, as shown by the lower visual analogue scale (VAS) scores of patients in the study group (p < 0.05). Patients administered with sufentanil showed better levels of mean arterial pressure (MAP) and oxygen saturation (SpO2) than remifentanil, suggesting better hemodynamic benefits provided by sufentanil (p < 0.01). During cardiovascular surgery performed in this study, sufentanil resulted in a higher safety profile by reducing significantly the incidence of adverse reactions (6 %) than remifentanil (30 %) (p < 0.01). Conclusions: Sufentanil exhibits a better anesthetic effect in patients undergoing cardiovascular surgery than remifentanil. It provides potent pain mitigation, effectively ameliorates patients’ hemodynamic status, and reduces the risk of adverse reactions. Future studies with larger sample sizes are required to validate these findings.

The prone position is extensively used to improve oxygenation in patients with severe acute respiratory distress syndrome caused by SARS-CoV-2 pneumonia. Occasionally, these patients exhibit cardiac and respiratory functions so severely compromised they cannot tolerate lying in the supine position, not even for the time required to insert a central venous catheter. The authors describe three cases of successful ultrasound-guided internal jugular vein cannulation in prone position. The alternative approach here described enables greater safety and well-being for the patient, reduces the number of episodes of decompensation, and risk of tracheal extubation and loss of in-situ vascular lines.

Introduction Increasing abdominal pressures could affect pulmonary compliance and cardiac performance, a fact based on which the aim of the present study to detect the cardiopulmonary burden of multiple retractors application during supine versus lateral abdominal surgeries. We hypothesized that surgical ring multiple retractors application would affect the pulmonary and cardiac functions during both lateral and supine abdominal surgeries. Methods Prospective observational comparative study on forty surgical patients subdivided into two groups twenty each, comparing pulmonary compliance and cardiac performance before, during and after retractors application, group (S) supine position cystectomy surgery, and group (L) lateral position nephrectomy surgery under general anesthesia, Composite 1ry outcome; dynamic compliance C-dyn and cardiac index CI and Other outcome variables ICON cardio-meter were also recorded. Results C-dyn and C-stat were significantly decreased late during retractor application in lateral compared to supine surgery with significant decrease compared to basal values all over the surgical time. CI was significantly increased after retractor removal in both of the study groups compared to basal values. PAWP was significantly increased in -lateral compared to supine surgery -with significant increase compared to basal value all over the surgical time in both of the study groups. significant increase in DO2I compared to basal value during both supine and lateral positions. Conclusion Surgical retraction results in a short-lived significant decreases in lung compliance and cardiac output particularly during the lateral-kidney position than the supine position compliance.

We describe the acute deterioration of a 29-year-old undergoing in vitro fertilisation. Late-onset critical ovarian hyperstimulation syndrome triggered a massive pulmonary embolism and subsequent cardiac arrest. While the prognosis was deemed to be poor, the patient made a full recovery. The potential reasons for this are explored.

A young woman presented to neurology with a 1 month history of progressive diplopia on lateral gaze and a 1 week history of headaches. On examination she was found to have complex ophthalmoparesis with binocular horizontal diplopia, failure of abduction bilaterally and limited upgaze with convergence-retraction nystagmus. The rest of the neurological examination was normal. She was admitted for investigations: blood, CT brain, MR brain and lumbar puncture results were normal. Anti-GD1a antibodies were strongly positive; anti-GM1, anti-GM2 and anti-GD1b were also positive. On follow-up 3 weeks later, the complex ophthalmoplegia persisted. It was decided to treat with intravenous immunoglobulins (IVIgs) with good response but recurrence at 2 weeks post infusion. She was treated with 4 weekly IVIg courses and remains responsive and controlled over 1 year since presentation but becomes symptomatic in the week running up to each dose; thus, disease modifying treatment is currently being considered.

We describe a 9-day-old baby with coarctation of the aorta who required urgent resuscitation including intubation and cardiac compressions. Despite the commencement of prostaglandin E1 (PGE1) to reopen the ductus arteriosus via the intraosseous route, postductal saturations remained unrecordable for a further 45 min. Within 3 min of administration of PGE1 via an umbilical venous catheter (UVC), saturations were recordable at 92%. UVC access was the sentinel intervention that irrevocably altered the clinical prognosis. This baby boy has survived with excellent neurodevelopmental outcome. Clinicians are less familiar with UVCs outside of the newborn period. Our data demonstrate successful placement in neonates up to 28 days of age. We hope this case encourages clinicians to consider the UVC as first-line central venous access in collapsed neonates. In cases of suspected left heart obstruction, we argue that UVCs are the optimal route.

Background Orthopedic procedures concerning the upper extremity commonly use a brachial plexus nerve block to achieve postoperative analgesia. The addition of dexamethasone to peripheral nerve blocks has been shown to significantly prolong its effect. We hypothesize that 1 mg doses of dexamethasone will prolong brachial plexus nerve block with similar efficacy to 4 mg and better than ropivacaine alone. Methods Seventy-nine patients who received a brachial plexus nerve block prior to undergoing upper extremity surgery were randomized to 1 of 4 treatment groups: group 1 received only 30 mL of 0.5% ropivacaine without dexamethasone (control); groups 2, 3, and 4 received 4, 2, and 1 mg of dexamethasone, respectively, added to 30 mL of 0.5% ropivacaine. Results Comparison of block duration, specifically “first signs of the block wearing off” to the 0-mg group, referencing the 1-, 2-, and 4-mg groups ( P = .02, .04, and .01, respectively) that received steroid adjuvant therapy demonstrated a significant increase in time until the block began to wear off. All study groups receiving steroids also demonstrated a significant increase in duration of the block prior to its effects being completely gone when compared with the control group ( P < .01 for all groups). Conclusions Our findings demonstrate that adjuvant dexamethasone can prolong brachial plexus nerve blocks effectively at low doses compared with high doses, in addition to prolonging analgesia compared with local anesthetic alone.

OBJECTIVE: To determine if surgery and anesthesia in the elderly may promote Alzheimer’s Disease and Related Dementias (ADRD). BACKGROUND: There is a substantial conflicting literature concerning the hypothesis that surgery and anesthesia promotes ADRD. Much of the literature is confounded by indications for surgery or has small sample size. This study examines elderly patients with appendicitis, a common condition that strikes mostly at random after controlling for some known associations. METHODS: A matched natural experiment of patients undergoing appendectomy for appendicitis versus control patients without appendicitis using Medicare data from 2002 to 2017, examining 54,996 patients without previous diagnoses of ADRD, cognitive impairment, or neurological degeneration, who developed appendicitis between ages 68 through 77 years and underwent an appendectomy (the “Appendectomy” treated group), matching them 5:1 to 274,980 controls, examining the subsequent hazard for developing ADRD. RESULTS: The hazard ratio (HR) for developing ADRD or death was lower in the Appendectomy group than controls: HR = 0.96 (95% CI 0.94, 0.98), P < 0.0001, (28.2% in Appendectomy versus 29.1% in controls, at 7.5 years). The HR for death was 0.97 (0.95, 0.99), P = 0.002, (22.7% versus 23.1% at 7.5 years). The HR for developing ADRD alone was 0.89 (0.86, 0.92), P < 0.0001, (7.6% in Appendectomy versus 8.6% in controls, at 7.5 years). No subgroup analyses found significantly elevated rates of ADRD in the Appendectomy group. CONCLUSIONS: In this natural experiment involving 329,976 elderly patients, exposure to appendectomy surgery and anesthesia did not increase the subsequent rate of ADRD.

Background: Current guidelines recommend electrical cardioversion (ECV) in patients with atrial fibrillation (AF) after at least 3 weeks of adequate non-vitamin K antagonist oral anticoagulant (NOAC) treatment without prior transesophageal echocardiography (TEE). However, in clinical practice in some centres, TEE is performed before ECV in patients with AF. The aim of the study was to evaluate prevalence of thromboembolic and hemorrhagic complications in patients with AF treated with NOACs and undergoing ECV without prior TEE. Methods: This observational, multicentre study included consecutive patients with AF treated with NOACs who were admitted for ECV without prior TEE. Thromboembolic events and major bleeding complications were investigated during a 30-day follow-up. Results: In the study group there were 611 patients, mean age was 66.3 ± 9.2 years, 40% were women. 52 (8.5%) patients had a low thromboembolic risk, 148 (24.2%) patients had an intermediate thromboembolic risk and 411 (67.2%) patients had a high thromboembolic risk. In the study group 253 (41.4%) patients were treated with rivaroxaban, 252 (41.2%) patients were treated with dabigatran and 106 (17.3%) patients were treated with apixaban. Reduced doses of NOACs were administered to 113 (18.9%) patients. In the entire study group, there were no thromboembolic events or major bleeding complications during the in-hospital stay and the 30-day follow-up. Conclusions: In this “real-world” study of AF patients treated with NOACs, it was proved that ECV is safe without a preceding TEE, regardless of the risk of thromboembolic complications and of the type of NOAC used.

Hyperbaric oxygen (HBO) therapy, the administration of pure oxygen at a pressure greater than the pressure of atmospheric oxygen, is a promising treatment for a range of neurological conditions, including traumatic brain injuries, Alzheimer's disease and comatose states. The research exploring the use of HBO therapy for neurological conditions is extremily exciting, and in this article, Sarah Palmer presents some key studies, demonstrating their findings and highlighting just how promising this potential therapy is.

Spinal anesthesia and peripheral nerve block anesthesia are used in total knee replacement. The aim of the study was to examine whether peripheral nerve block anesthesia would provide a more stable hemodynamic profile and analgesic effect in elderly patients undergoing total knee replacement, as compared to spinal anesthesia. This is a single-center case-control trial, with patients from our prospectively followed registry. The patients were divided into two groups, those with peripheral nerve block anesthesia and spinal anesthesia. Propensity score analysis was performed in 1:1 ratio. The primary outcome was analgesia with total analgesic effect and the secondary outcome was intraoperative hemodynamic status. The patients in peripheral nerve block anesthesia group had a longer length of analgesia (606.19±219.35 vs 359.48±106.82, P

INTRODUCTION: The Lancet Commission on Global Surgery indicators for monitoring anesthetic and surgical care allow the identification of access barriers, evaluate the safety of surgeries, facilitate planning, and assess changes over time. The primary objective was to measure these indicators in all health facilities of a Peruvian region in 2020. METHODS: This was an ambispective observational study to measure the anesthetic and surgical care indicators in Piura, a region in Peru, between January 2020 and June 2021. Public and private health facilities in the Piura region that performed surgical care or had specialists from any surgical specialty participated in the study. Data were collected from all regional health facilities that provided surgical care to estimate the density of surgical workforce. Likewise, the percentage of the population with access to an operating room within 2 h was estimated using georeferenced tools. Finally, a public database was accessed to determine the surgical volume, the percentage of the regional population protected with health insurance. RESULTS: In 2020, 88.4% of the inhabitants of this Peruvian region had access to timely essential surgery. There were 18.4 surgical specialists and 1174 surgeries per 100,000 populations, and 91% of the population had health insurance. In addition, there was a rate of 2.1 working operating rooms per 100,000 inhabitants in 2021. CONCLUSIONS: This Peruvian region presented an increasing trend with respect to the population’s access to essential and timely surgical care, and health insurance coverage. However, the workforce distribution was inequitable among the provinces of the region, the surgical volume was reduced, and timely access was hindered because of the SARS-CoV-2 pandemic.

PURPOSE: Several bedside clinical tests have been proposed to predict difficult tracheal intubation. Unfortunately, when used alone, these tests show less than ideal prediction performance. Some multivariate tests have been proposed considering that the combination of some criteria could lead to better prediction performance. The goal of our research was to compare three previously described multivariate models in a group of adult patients undergoing general anesthesia. METHODS: This study included 220 patients scheduled for elective surgery under general anesthesia. A standardized airway evaluation which included modified Mallampati class (MM), thyromental distance (TMD), mouth opening distance (MOD), head and neck movement (HNM), and jaw protrusion capacity was performed before anesthesia. Multivariate models described by El-Ganzouri et al., Naguib et al., and Langeron et al. were calculated using the airway data. After anesthesia induction, an anesthesiologist performed the laryngoscopic classification and tracheal intubation. The sensitivity, specificity, and receiver operating characteristic (ROC) curves of the models were calculated. RESULTS: The overall incidence of difficult laryngoscopic view (DLV) was 12.7%. The area under curve (AUC) for the Langeron, Naguib, and El-Ganzouri models were 0.834, 0.805, and 0.752, respectively, (Langeron...>...El-Ganzouri, p...=...0.004; Langeron...=...Naguib, p...=...0.278; Naguib...=...El-Ganzouri, p...=...0.101). The sensitivities were 85.7%, 67.9%, and 35.7% for the Langeron, Naguib, and El-Ganzouri models, respectively. CONCLUSION: The Langeron model had higher overall prediction performance than that of the El-Ganzouri model. Additionally, the Langeron score had higher sensitivity than the Naguib and El-Ganzouri scores, and therefore yielded a lower incidence of false negatives.

Propofol is widely used to sedate agitated patients in intensive care units. However, it can cause a rare but fatal complication, propofol-related infusion syndrome (PRIS). The pathophysiology of PRIS is not clear, and there is no definitive diagnosis and treatment. We report a successfully treated case of PRIS in a critically ill patient receiving low-dose propofol infusion. A 59-year-old male patient complaining of sudden chest pain repeatedly collapsed in an ambulance and the emergency room, and veno-arterial extracorporeal membrane oxygenation was delivered. He was diagnosed with a total occluded left anterior descending coronary artery in coronary angiography. On day 20, he showed arrhythmia, increased creatinine kinase (CK), and increased CK-MB and troponin I, accompanied by unstable hemodynamic status despite high-dose vasopressors. He was administered propofol for 20 days at an average dose of 1.3 mg/kg/hr owing to issues with agitation and ventilator synchrony. We strongly suspected PRIS and immediately discontinued propofol infusion, and he was successfully treated with aggressive supportive care. PRIS can occur in patients administered propofol for a prolonged period at low doses. Thus, clinicians should use propofol with caution for PRIS and change to alternative sedatives for long-term sedation.

Background and purpose Mild traumatic brain injury (mTBI) in patients on antiplatelet (AP), anticoagulant (AC) or direct oral anticoagulant (DOAC) medication has become a systematic indication for head CT. However, the over-risk and impact of the intracranial hemorrhages (IH) detected with CT in this population remain unclear and need to be assessed. Materials and methods We prospectively assessed head CTs performed in adults taking AP/AC/DOAC referred after a mTBI to our Emergency Departments between September 2016 and January 2018. Frequency, type and severity of IH were described and frequency was analyzed as a function of treatment. Results 840 patients were prospectively included. 58.9% were treated with AP, 23.7% with AC, 11.7% with DOAC and 5.7% with a combination of antithrombotic agents. The rate of IH detected with head CT was 5.8% (n = 49), of which 81.6% (n = 40) and 18.4% (n = 9) with minor and intermediate severity respectively. No patient required surgical care and no death occurred. No statistically significant difference was found in treatment distribution between patients with or without IH (p = 0.98). Among the patients who discontinued their antithrombotic treatment after mTBI, three experienced thrombotic events during the hospitalization. Conclusions Our results showed a low frequency and severity of IH in mTBI patients indifferently treated with AP, AC or DOAC, without secondary neurological deterioration, death or need of surgical care. Our study suggests the limited benefit of systematic CT head scan as a standard practice for the management of mTBI patients under antithrombotic therapy.

Stenting for lower tracheal stenosis is a tricky situation and for the safe conduct of anesthesia, it is imperative to maintain spontaneous respiration. Airway topicalization is routinely recommended for anticipated difficult airway. We report a case of upper airway obstruction following lidocaine nebulization in a patient to be taken for tracheal stenting for lower tracheal stenosis. We would like to highlight that close monitoring of the patient is advisable during airway topicalization to detect any airway obstruction at the earliest and how fiberoptic intubation can play a pivotal role to secure the airway in an emergency scenario.

Dabigatran, a novel oral anticoagulant, is a direct thrombin inhibitor and is being increasingly used owing to the advantage of dosing without the need for laboratory monitoring. While extensive skin necrosis is known to be associated with oral anticoagulants such as warfarin and factor Xa inhibitors, dabigatran toxicity typically manifests with bleeding, especially in the elderly. We describe a 70-year-old woman who was prescribed dabigatran for the treatment of unprovoked deep venous thrombosis. She developed bleeding diathesis along with extensive skin necrosis and acute kidney injury shortly after commencing the drug. Haemodialysis was given in view of dabigatran toxicity and complications of kidney dysfunction which resolved promptly over a week. However, the patient succumbed to severe sepsis from secondary skin infections. It is crucial to closely monitor for signs of dabigatran toxicity, especially in the elderly patients.

Dysfunction of fear memory systems underlie a cluster of clinically important and highly prevalent psychological morbidities seen in perioperative and critical care patients, most archetypally posttraumatic stress disorder (PTSD). Several sedative-hypnotics and analgesics are known to modulate fear systems, and it is theoretically plausible that clinical decisions of the anesthesiologist could impact psychological outcomes. This review aims to provide a focused synthesis of relevant literature from multiple fields of research.There is evidence in some contexts that unconscious fear memory systems are less sensitive to anesthetics than are conscious memory systems. Opiates may suppress the activation of fear systems and have benefit in the prevention of PTSD following trauma. There is inconsistent evidence that the use of propofol and benzodiazepines for sedation following trauma may potentiate the development of PTSD relative to other drugs. The benefits of ketamine seen in the treatment of major depression are not clearly replicated in PTSD-cluster psychopathologies, and its effects on fear processes are complex.There are multiple theoretical mechanisms by which anesthetic drugs can modulate fear systems and clinically important fear-based psychopathologies. The current state of research provides some evidence to support further hypothesis investigation. However, the absence of effectiveness studies and the inconsistent signals from smaller studies provide insufficient evidence to currently offer firm clinical guidance.

A 58-year-old man with diabetes, alcoholic cirrhosis and a history of cerebral contusion and traumatic subarachnoid haemorrhage visited the hospital after his first convulsion, which lasted for 30 s. He was intubated because of the prolonged disturbance of consciousness caused by his intermittent

A 38-year-old man presented at the emergency department with abdominal pain, vomiting, generalised weakness and altered consciousness. He had been ingesting opioids for over 5 years and had several past hospital admissions for abdominal pain. His investigations showed deranged liver function tests, anaemia and basophilic stippling on the peripheral blood smear. Further investigations revealed a significant increase in the serum lead level. We started chelation with peroral penicillamine 250 mg every 6 hours for 2 days and switched to intramuscular dimercaprol 4 mg/kg every 12 hours and intravenous calcium ethylenediamine tetraacetic acid 50 mg/kg in two divided doses daily for the next 5 days. We then discharged him home; he had become clinically stable by that time. We repeated his lead level and followed him up in the clinic. In this report, we emphasise the consideration of lead toxicity in opioid abusers and bring to attention a rare way of lead chelation in resource-limited settings.

Methaemoglobin is a form of haemoglobin with oxidised ferric (+3) iron rather than ferrous (+2) iron, which causes a leftward shift in the oxyhaemoglobin dissociation curve and prevents oxygen delivery. Anaesthesiologists need to be familiar with this differential diagnosis for hypoxia given the use of drugs in the perioperative setting known to induce methaemoglobinaemia, including benzocaine and lidocaine, antibiotics such as dapsone and anaesthetic gases, including nitric oxide. This case report details an interesting case of symptomatic methaemoglobinaemia in the perioperative period in the setting of dapsone use and an erector spinae block performed with ropivacaine.

Patients with severe, COVID-related multi-organ failure often require extracorporeal life support (ECLS) such as extracorporeal membrane oxygenation (ECMO) or continuous renal replacement therapy (CRRT). An ECLS can alter drug exposure via multiple mechanisms. Remdesivir (RDV) and its active metabolite GS-441524 are likely to interact with ECLS circuits, resulting in lower than expected exposures. We evaluated circuit-drug interactions in closed loop, ex vivo ECMO and CRRT circuits. We found that mean (standard deviation) recovery of RDV at 6 hours after dosing was low in both the ECMO (33.3% [2.0]) and CRRT (3.5% [0.4]) circuits. This drug loss appears to be due primarily to drug adsorption by the circuit materials and potentially due to metabolism in the blood. GS-441524 recovery at 6 hours was high in the ECMO circuit 75.8% (16.5); however, was not detectable at 6 hours in the CRRT circuit. Loss in the CRRT circuit appears to be due primarily to efficient hemodiafiltration. The extent of loss for both molecules, especially in CRRT, suggests that in patients supported with ECMO and CRRT, RDV dosing adjustments are needed.

A 12-year-old girl underwent surgery for Lenke type 4 adolescent idiopathic scoliosis. After scoliosis correction, the transcranial motor-evoked potential (Tc-MEP) showed no alarm. However, the Tc-MEP amplitude had declined ~10 min after correction, with a normal blood pressure (BP) and body temperature and without any technical monitoring errors. Therefore, we suspected indirect spinal cord ischaemia because of the delayed true-positive Tc-MEP alarm. All the strong corrections made loss of Tc-MEP and all the correction releases made recovers of waveform. Finally, a weak correction was performed, and the Tc-MEP amplitude was recovered. Because transient spinal cord ischaemia due to correction of triple curves may cause a delayed monitoring alarm, the monitoring team should frequently check Tc-MEP after these manoeuvres. This patient had no neurological deficits and was considered to be a rescue case.

Spontaneous intracranial hypotension (SIH) is characterised by postural headache and a cerebrospinal fluid (CSF) pressure of ≤6 cmH20 measured with the patient in the lateral decubitus position. Other symptoms include tinnitus, altered hearing, diplopia, photophobia, nausea and neck stiffness, and must not have occurred within a month of dural puncture. Symptoms typically remit after normalisation of CSF pressure or successful sealing of the CSF leak. An epidural blood patch (EBP) is a treatment option in those who have not responded to bed rest, fluids, non-steroidal anti-inflammatories or caffeine. We present a case of SIH successfully treated with both conservative measures and EBP. We compare our case with similar cases in the literature and summarise what is known about EBP for SIH to help clinicians take a more informed approach to managing such patients.

Following non-elective orthopaedic surgery, a 61-year-old man with poorly controlled type 2 diabetes mellitus on empagliflozin developed high anion gap metabolic acidosis in the high-dependency unit. Metabolic acidosis persisted despite intravenous sodium bicarbonate, contributing to tachycardia and a run of non-sustained ventricular tachycardia. He was euglycaemic throughout hospital admission. Investigations revealed elevated urine and capillary ketones, and a diagnosis of sodium–glucose cotransporter-2 inhibitor-associated euglycaemic diabetic ketoacidosis was made. He was treated with an intravenous sliding scale insulin infusion and concurrent dextrose 5% with potassium chloride. Within 24 hours of treatment, his arterial pH, anion gap and serum bicarbonate levels normalised. After a further 12 hours, the intravenous insulin infusion was converted to a basal/bolus regimen of subcutaneous insulin, and he was transferred to the general ward. He was discharged well on subcutaneous insulin 6 days postoperatively.

Nitrous oxide (NO) is an inhalant that has become increasingly popular as a recreational drug. While it is presumed to be harmless, a number of adverse effects of NO have been described. We discuss the case of a 24-year-old man with no medical history, who initially presented to the emergency department with progressive polyneuropathy caused by vitamin B12 deficiency after NO abuse. Two days after being discharged with hydroxocobalamin supplementation, the patient returned with a severe headache, blurry vision and slurred speech. Imaging revealed cerebral venous sinus thrombosis. Hypercoagulability workup showed slightly elevated homocysteine and normalised vitamin B12 after supplementation. Genetic testing showed a heterozygous prothrombin G20210A mutation. He was treated with low-molecular-weight heparin followed by dabigatran. We hypothesise that NO use may increase the risk of developing cerebral venous thrombosis, especially in patients with multiple risk factors and elevated homocysteine levels.

Vancomycin is a widely used antibiotic and rarely can cause drug-induced thrombocytopenia. A patient with hospital-acquired meningitis after neurosurgery was treated with systemic and intrathecal vancomycin. On 9th day of antibiotic treatment, the patient’s platelets dropped to 0.68×109/L. Multiple platelet transfusions had minimal influence on platelet count. After cessation of vancomycin therapy, platelets returned to normal values without any additional interventions. Diagnosis of vancomycin-induced thrombocytopenia was confirmed by detection of drug-dependent antiplatelet IgG antibodies.

Hyponatraemia is the most common electrolyte disturbance observed in hospital inpatients. We report a 90-year-old woman admitted generally unwell following a fall with marked confusion. Examination revealed a tender suprapubic region, and investigations observed elevated inflammatory markers and bacteriuria. Admission investigations demonstrated a serum sodium of 110 mmol/L with associated serum osmolality 236 mmol/kg and urine osmolality 346 mmol/kg. She was treated for hyponatraemia secondary to syndrome of inappropriate antidiuretic hormone (SIADH) and urosepsis. However, her serum sodium failed to normalise despite fluid restriction, necessitating treatment with demeclocycline and hypertonic saline. Despite slow reversal of hyponatraemia over 1 month, the patient developed generalised seizures with pontine and thalamic changes on MRI consistent with osmotic demyelination syndrome (ODS). This case highlights the risk of ODS, a rare but devastating consequence of hyponatraemia treatment, despite cautious sodium correction.

While people 65 years of age and older represent 16% of the population in the United States, they account for40% of surgical procedures performed each year. Maintaining brain health after anesthesia and surgery is not only important to our patients, but it is also an increasingly important patient safety imperative for the specialty of anesthesiology. Aging is a complex process that diminishes the reserve of every organ system and often results in a patient who is vulnerable to the stress of surgery. The brain is no exception, and many older patients present with preoperative cognitive impairment that is undiagnosed. As we age, a number of changes occur in the human brain, resulting in a patient who is less resilient to perioperative stress, making older adults more susceptible to the phenotypic expression of perioperative neurocognitive disorders. This review summarizes the current scientific and clinical understanding of perioperative neurocognitive disorders and recommends patient-centered, age-focused interventions that can better mitigate risk, prevent harm, and improve outcomes for our patients. Finally, it discusses the emerging topic of sleep and cognitive health and other future frontiers of scientific inquiry that might inform clinical best practices.

Children undergoing general anesthesia and surgery in the early years of life are exposed to the possible neurotoxicity of anesthetic agents. Prospective studies have shown deficits in behavior, executive function, social communication, and motor function in children undergoing anesthesia and surgery. Different biomarkers of neuronal injury have been evaluated neuronal injury in the pediatric population, among which neurofilaments represent a significant advantage as they are proteins exclusively expressed in neuronal tissue. Our aim was to evaluate the utility of serum neurofilament light (NfL) as a prognostic biomarker of neuronal injury in the pediatric population. A literature search was performed on PubMed, Embase, and Cochrane Databases in November 2022 for studies concerning serum NfL in the pediatric population in addition to a neurological assessment. Inclusion criteria were as follows: (1) prospective or retrospective studies, (2) studies including pediatric population until the age of 18 years, (3) serum NfL sampling, and (4) evaluation of neurological outcome. Data collection regarding study design, pediatric age, serum NfL levels, and results for neurological assessment were extracted from each study. Four manuscripts met the inclusion criteria and evaluated the prognostic utility of serum NfL in neonatal encephalopathy in correlation with the neurodevelopmental outcome that was assessed by the Bayley Scales of Infant Development until the age of 2 years. Children with neonatal encephalopathy showed significantly higher serum NfL vs. healthy controls and high serum NfL levels predicted an adverse neurological outcome. The decrease of serum NfL to a nadir point between 10 and 15 years old reflects the brain growth in healthy controls. No studies were available in the perioperative period. Conclusions: Serum NfL is a valuable biomarker in evaluating neuronal injury in the pediatric population. Further studies with perioperative serial sampling of serum NfL combined with standardized neurodevelopmental tests should be conducted to evaluate the neurotoxicity of anesthetic agents and monitor the effectiveness of specific neuroprotective strategies in pediatric patients undergoing anesthesia and surgery. What is Known: • Preclinical animal data have shown neurotoxicity of the anesthetic agents in the developing brain. • Data regarding anesthetic neurotoxicity in humans show limitations and no objective tools are available. What is New: • This systematic review showed that serum NfL is a valuable biomarker of neuronal injury in the pediatric population. • Perioperative use of serum NfL may be considered in future trials evaluating anesthetic neurotoxicity in the pediatric population and in monitoring neuroprotective strategies.

Background: Chorea-acanthocytosis (ChAc) is the most common type of neuroacanthocytosis syndromes. Characteristic movement disorders of ChAc are choreiform movements affecting both trunk and extremities. Acanthocytosis in peripheral blood smear, elevated serum creatine kinase, atrophy of heads of caudate nuclei and dilation of the anterior horn of the lateral ventricles in magnetic resonance imaging could assist the diagnosis of ChAc. Objective: We aimed to report on the use of acupuncture to successfully improve ChAc symptoms. Method: A patient with definite ChAc was admitted, who had suffered from involuntary tongue protrusion for about 10 years. Acupuncture treatment was administrated for 3 times a week for 2 months. The chorea tremor control area, Baihui (GV20), Sishencong (EX-HN1), Shenting (GV24), Benshen (GB13, bilateral), Yintang (GV29), Neiguan (PC6, bilateral), Tongli (HT5, bilateral), Zusanli (ST36, bilateral), Sanyinjiao (SP6, bilateral), Dicang (ST4, bilateral), Chengjiang (CV24), Lianquan (CV23), Jinjin (EX-HN12) and Yuye (EX-HN13) were selected as acupunture points. Results: Previous drug dosage was reduced and the frequency of involuntary tongue protrusion was significantly reduced. Other clinical symptoms were also well controlled. Peripheral blood smear still indicated an increased proportion of red lineage, but blood analyses revealed improvement at follow-up. Conclusions: For patients who do not response well to conventional medical treatments, acupuncture might be used as an alternative treatment for symptoms related to ChAc.

Cutaneous feedback from feet is involved in regulation of muscle activity during locomotion, and the lack of this feedback results in motor deficits. We tested the hypothesis that locomotor changes caused by local unilateral anesthesia of paw pads in the cat could be reduced/reversed by electrical stimulation of cutaneous and proprioceptive afferents in the distal tibial nerve during stance. Several split-belt conditions were investigated in four adult female cats. In addition, we investigated the effects of similar distal tibial nerve stimulation on overground walking of one male cat that had a transtibial, bone-anchored prosthesis for 29 months and, thus, had no cutaneous/proprioceptive feedback from the foot. In all treadmill conditions, cats walked with intact cutaneous feedback (control), with right fore- and hindpaw pads anesthetized by lidocaine injections, and with a combination of anesthesia and electrical stimulation of the ipsilateral distal tibial nerve during the stance phase at 1.2× threshold of afferent activation. Electrical stimulation of the distal tibial nerve during the stance phase of walking with anesthetized ipsilateral paw pads reversed or significantly reduced the effects of paw pad anesthesia on several kinematic variables, including lateral center of mass shift, cycle and swing durations, and duty factor. We also found that stimulation of the residual distal tibial nerve in the prosthetic hindlimb often had different effects on kinematics compared with stimulation of the intact hindlimb with paw anesthetized. We suggest that stimulation of cutaneous and proprioceptive afferents in the distal tibial nerve provides functionally meaningful motion-dependent sensory feedback, and stimulation responses depend on limb conditions.

Catheter ablation procedures for arrhythmias or implantation and/or extraction of cardiac pacemakers can present many clinical challenges. It is imperative that there is clear communication and understanding between the anesthesiologist and electrophysiologist during the perioperative period regarding the mode of ventilation, hemodynamic considerations, and various procedural complications. This article provides a comprehensive narrative review of the anesthetic techniques and considerations for catheter ablation procedures, ventilatory modes using techniques such as high-frequency jet ventilation, and strategies such as esophageal deviation and luminal temperature monitoring to decrease the risk of esophageal injury during catheter ablation. Various hemodynamic considerations, such as the intraprocedural triaging of cardiac tamponade and fluid administration during catheter ablation, also are discussed. Finally, this review briefly highlights the early research findings on pulse-field ablation, a new and evolving ablation modality.

Objective To assess the value of a morphine Patient Controlled Intravenous Analgesia (PCIA) after Tonsillectomies (TE). Methods 30 adult patients were treated with oral analgesics (protocol group) and compared to 30 patients treated with a morphine PCIA for the first 3 Postoperative Days (PODs) after TE. Average and maximum pain severities (Numeric Rating Scale – NRS: 0–10) on PODs 1–3, analgesic score, quality of life, patient satisfaction and side effects were defined as outcome measures. Results Average pain severities of the protocol and the PCIA group were of similar magnitude (NRS) (POD1: 4.48 vs. 4.71 [p = 0.68], POD2: 4.75 vs. 4.22 [p = 0.32] and POD3: 4.44 vs. 4.25 [p = 0.71]). Maximum pain intensities on POD1 (p = 0.92), POD2 (p = 0.51) and POD3 (p = 0.36) were also comparable between both groups. Patients with a PCIA consumed significantly more opioids (p = 0.001) without significant more side-effects. Conclusion The PCIA did not provide a superior pain control compared to oral analgesics. In view of the considerable effort and the high opioid consumption, it cannot be recommended as a standardized application for pain control after TE.

Summary Introduction Vocal cord vibration after transoral CO2 LASER-guided thyroarytenoid (TA) myoneurectomy in adductor spasmodic dysphonia (AdSD) patients is unclear to date. The precise vibratory patterns in AdSD patients are difficult to evaluate with routine videolaryngostroboscopy. High-speed videolaryngoscopy (HSV) is an ideal choice to evaluate such patients. This study was performed to compare pre- and postoperative, after 6 months, vocal fold vibratory onset delay (VFVOD) and closed phase glottal cycle (CPGC) in AdSD patients following transoral CO2 LASER-guided TA myoneurectomy using the HSV. Materials and methods Retrospective study, conducted from January, 2016 to January, 2019, of the AdSD patients who underwent transoral CO2 LASER-guided TA myoneurectomy using the HSV. Patient data were acquired from the hospital database to evaluate VFVOD and CPGC from HSV recordings of the patients. VFVOD was calculated as sum of prephonatory delay (PPD) and steady-state delay (SSD). The PPD and SSD were evaluated and compared separately for each patient. The MedCal Version 19.2.6 was used for data analysis. Paired sample t test was performed to compute the significance of the difference between the mean of the dataset. A P value less than 0.05 was considered significant. Results A total of nine patients were included in the study, out of which three were females and six were males. The average age was 45.5 ± 6.9 years. The mean of postoperative PPD (166.8 ± 22.1), SSD (76.5 ± 8.6), and CPGC (62.6 ± 4.8) were significantly less than mean of preoperative PPD (222.6 ± 22.1), SSD (97.7 ± 9.5), and CPGC (71.6 ± 5 %), with P values of 0.0007, 0.0001, and 0.0001, respectively. Conclusions There was a significant decrease in VFVOD and CPGC posttransoral CO2 LASER-guided TA myoneurectomy in AdSD patients after 6 months follow-up. This study also establishes efficiency of the HSV to measure the vocal cord vibration in the patients with AdSD. The primary limitations of the study were the small sample size and its retrospective nature. Future prospective studies with increased sample size can further substantiate the findings of the work performed here.

Neurogenic bladder and bowel are two critical autonomic complications following traumatic spinal cord injury (TSCI). Chronic lower urinary tract and bowel dysfunctions can lead to secondary complications, drastically affect the quality of life and significantly increase the risk of hospital readmission and mortality. Other than symptomatic treatments, a few effective therapies are available. Combined acupuncture and moxibustion therapy has positive effects on improving nerve repair and functional recovery in the early phases following TSCI. However, whether it is effective for TSCI-related chronic urinary and bowel dysfunctions remains unknown. This report presents the case of a 26-year-old male patient who experienced neurogenic bladder and bowel dysfunction following TSCI due to an accidental fall from height for more than 10 months and visited our department for combined acupuncture and moxibustion therapy. After 48 treatment sessions, he regained voluntary urination and defecation to a large extent. Urodynamic testing showed recovered bladder compliance and improved detrusor contractility. Symptom assessment with the Qualiveen Short-Form and neurogenic bowel dysfunction scores demonstrated reduced symptom severity. This case suggests that combined acupuncture and moxibustion therapy might help to restore the physiological functions of the lower urinary and digestive tracts following TSCI and might be a promising alternative for the treatment of neurogenic bladder and bowel dysfunction in patients with TSCI.

(Background) Tranexamic acid (TXA) is widely used in hip and knee arthroplasty to reduce perioperative bleeding. Recently, its use has been expanded to arthroscopic surgery. The purpose of this study was to evaluate the efficacy of preoperative use of TXA in arthroscopic rotator cuff repair (RCR).(Methods) A cohort comprising 129 consecutive patients who underwent arthroscopic primary RCR at our institution was retrospectively investigated according to whether they received TXA (April 2018 to December 2020, TXA group, n=64) or did not receive TXA (April 2016 to March 2018, non-TXA group, n=65). TXA was administered at a dose of 1 g intravenously. Rotator cuff tears were repaired by the suture bridge technique. Videos of the arthroscopic procedures were reviewed and rated for visual clarity using a 10-point numeric rating scale. Arthroscopic procedures were divided into glenohumeral, resection of bursal tissue and acromioplasty, and RCR steps. Each step was rated separately. Age, sex, body mass index, hemoglobin level before and on days 1 and 7 after surgery, operating time, mean arterial pressure, tear size, and number of anchors used for cuff repair were compared between the two groups. (Results) There were no statistically significant differences in the patient demographic data. The operating time was significantly shorter in the TXA group than in non-TXA group (97.8 ± 21.8 min vs 116.2 ± 26.0 min). The clarity of the visual field was similar between the two groups during the glenohumeral phase but was significantly higher in the TXA group during the resection of bursal tissue and acromioplasty and RCR phases. Hemoglobin level was not significantly different between the groups on postoperative day 1 but was significantly higher in the TXA group on day 7.(Conclusion) Administration of a single intravenous dose of TXA improved visual clarity in arthroscopic RCR, decreased the total operating time, and reduced hemoglobin loss on postoperative day 7.

Background The purpose of study was to compare the changes in blood pressure in patients undergoing phacoemulsification cataract surgery under topical and peribulbar anaesthesia during preoperative, intraoperative and postoperative period. Methods In this prospective cohort study, 240 patients undergoing phacoemulsification were divided into topical (Group 1) and peribulbar (Group 2) equally. Proparacaine 0.5% drops were used for topical anaesthesia, and Inj lignocaine with Inj bupivacaine were used to give peribulbar anaesthesia. Preoperative blood pressure was taken 30 min before surgery with automated sphygmomanometer. Intraoperative blood pressure was taken during phacoemulsification, and postoperative blood pressure was taken 1 h after surgery. Outcomes assessed were systolic, diastolic and mean blood pressure. Results Systolic blood pressure in Group 1 was significantly increased in the intraoperative phase, whereas it was significantly decreased in Group 2 in the intraoperative phase. Diastolic and mean blood pressure in Group 1 showed no significant change, whereas in Group 2, both showed significant reduction in intraoperative and postoperative phases. Conclusion The increase in intraoperative systolic blood pressure in topical group could be due to discomfort from microscope light, iris manipulation, irrigation and aspiration during surgery. The decrease in intraoperative systolic and diastolic blood pressure in peribulbar group could be due to systemic absorption of local anaesthetic. The mean preoperative systolic blood pressure was also higher in the topical group, which could be due to anxiety or stress under topical anaesthesia. The changes in blood pressure need to be observed so that timely intervention can be made to achieve favourable postoperative outcome.

In this study, the antioxidant, anti-inflammatory, and neuroprotective effects of kefir were investigated in spinal cord injury that was experimentally created on rats with a compression trauma model. A total of 56 Wistar-Albino male rats were used in the study. Daily freshly prepared 18 ml/kg/day of kefir was given by oral gavage to animals 7 days before and during the trauma and during the trauma. Spinal cord injury was created according to the weight drop method. On the 1st and 7th days before euthanasia, intracardiac blood was collected for analysis, and then they were sacrificed. The damaged spinal cord segments were examined biochemically, immunohistochemically, and histopathologically. When compared to the sham groups, kefir had a positive effect in the preconditioning and treatment groups by decreasing spinal cord bleeding, edema, myelin sheath damage, liquefactive necrosis, neuronal necrosis, selectivity of canalis centralis, and gitter cell levels significantly. When compared to the sham groups, kefir was found to have a positive effect in the treatment groups by decreasing the neuron specific enolase (NSE), ionized calcium binding adapter molecule 1 (IBA-1), inducible nitric oxide synthase (INOS), cyclooxygenase 2 (COX-2) and myelin basic protein (MBP) levels significantly on the 1st and 7th days, and by increasing the glial fibrillary acidic protein (GFAP) level significantly. As a result, it was demonstrated that kefir had a protective and therapeutic effect on spinal cord injury.

Background: Fluid resuscitation is a fundamental intervention in patients with hypovolemic shock resulting from trauma. Appropriate fluid resuscitation in trauma patients could reduce organ failure, until blood components are available, and hemorrhage is controlled. We conducted a systematic review and meta-analysis assessing the effect of hypertonic saline/dextran or hypertonic saline for fluid resuscitation on patient outcomes restricted to adults with hypovolemic shock. Methods: We conducted a search of electronic information sources, including PubMed, Embase, Web of Science, Cochrane library and bibliographic reference lists to identify all randomized controlled trials (RCTs) investigating outcomes of crystalloids versus colloids in patients with hypovolemic shock. We calculated the risk ratio (RR) or mean difference (MD) of groups using fixed or random-effect models. Results: Fifteen studies including 3264 patients met our inclusion criteria. Survival to hospital discharge rate between research groups varied and amounted to 71.2% in hypertonic saline/dextran group vs. 68.4% for isotonic/normotonic fluid (NS) solutions (odds ratio [OR] = 1.19; 95% confidence interval [CI] 0.97–1.45; I 2 = 48%; p = 0.09). 28- to 30-days survival rate for hypertonic fluid solutions was 72.8% survivable, while in the case of isotonic fluid (NS) — 71.4% (OR = 1.13; 95% CI 0.75–1.70; I 2 = 43%; p = 0.56). Conclusions: This systematic review and meta-analysis, which included only evidence from RCTs hypertonic saline/dextran or hypertonic saline compared with isotonic fluid did not result in superior 28- to 30-day survival as well as in survival to hospital discharge. However, patients with hypotension who received resuscitation with hypertonic saline/dextran had less overall mortality as patients who received conventional fluid.

Background & aims Dysphagia can be a consequence of prolonged hospitalization in intensive care units (ICUs) due to severe SARS-CoV-2 pneumonia. This study aims at Identifying the risk factors for dysphagia in ICU patients with COVID-19 pneumonia requiring invasive mechanical ventilation, and at determining the frequency of postextubation dysphagia in this population. Methods Observational, descriptive, retrospective, cohort study of SARS-CoV-2 pneumonia patients admitted into the ICUs from March to May 2020. The Modified Viscosity Volume Swallowing Test (mV-VST) was used to screening for dysphagia during the first 48 h of extubation in patients requiring mechanical ventilation. Descriptive statistics, univariate and multivariate analyses were conducted. A logistic regression was applied to construct a predictive model of dysphagia. Results A total of 232 patients were admitted into the ICUs (age [median 60.5 years (95% CI: 58.5 to 61.9)]; male [74.1% (95% CI: 68.1 to 79.4)]; APACHE II score [median 17.7 (95% CI: 13.3 to 23.2)]; length of mechanical ventilation [median 14 days (95% CI: 11 to 16)]; prone position [79% (95% CI: 72.1 to 84.6)]; respiratory infection [34.5% (95% CI: 28.6 to 40.9)], renal failure [38.5% (95% CI: 30 to 50)])). 72% (167) of patients required intubation; 65.9% (110) survived; and in 84.5% (93) the mV-VST was performed. Postextubation dysphagia was diagnosed in 26.9% (25) of patients. APACHE II, prone position, length of ICU and hospital stay, length of mechanical ventilation, tracheostomy, respiratory infection and kidney failure developed during admission were significantly associated (p

Nonopioid analgesics are commonly used to augment or replace opioids in the perioperative setting. Perianesthesia nurses must consider timing and appropriateness when administering these medications to patients in the preoperative area or the postanesthesia care unit, particularly when other medications with sedative effects are being given. Gabapentin, originally proposed as an anticonvulsant medication, promotes analgesia and reduces risk for postoperative nausea and vomiting. This review examines the effect of gabapentin on postoperative pain.A systematic review.CINAHL, PubMed, and Cochrane Review databases were searched to find a total of 93 sources that examined gabapentin and postoperative pain. After applying inclusion and exclusion criteria, four randomized controlled trials (RCT) were reviewed. Postoperative pain within the 24 hours of surgery was measured as the primary outcome using the visual analog scale in all sources FINDINGS: Three of the four reviewed RCTs determined gabapentin was both statistically and clinically significant in reducing postoperative pain, and all four sources showed a reduction in opioid consumption during the immediate postoperative period, which promoted patient satisfaction.Further study of gabapentin and postoperative pain is needed employing rigorous and robust methodology and diversity of the sample selections.

To examine the effect of bispectral index (BIS)-guided anesthesia on the incidence of postoperative delirium (POD) in elderly patients undergoing surgery.A systematic review, meta-analysis, and trial sequential analysis (TSA).In the operating room, postoperative anesthesia care units (PACU), and ward.Elderly patients (60 years old) undergoing surgery.The EMBASE, MEDLINE, and CENTRAL databases were searched systematically from their inception until December 2020 for randomized controlled trials comparing BIS and usual care or blinded BIS.Ten trials (N = 3,891) were included for quantitative meta-analysis. In comparison to the control group, there was no significant difference in the incidence of POD in elderly patients randomized to BIS-guided anesthesia (odds ratio [OR] 0.71, 95% CI 0.47-1.08, IThe authors' meta-analysis demonstrated that BIS-guided anesthesia was not associated with a reduced incidence of POD, but it was associated with a reduced incidence of POCD and improved recovery parameters.

Summary Background & aims ESPEN guidelines advocate that energy needs of critically ill patients with COVID 19 should be assessed using indirect calorimetry, if safely available. This study described energy needs of intubated patients with COVID-19 and explores whether neuromuscular blockade administration (NMBAs) is associated with altered energy expenditure. Methods Resting energy expenditure (REE) and respiratory exchange rate (RER) evaluated among critically ill intubated COVID-19 patients until 28th day of intensive care unit stay (ICU–S) by indirect calorimetry. Paralysed patients were defined as those with drug induced paralysis using cicatracurium, for at least 3 days during their ICU-S. Results 34 adult COVID 19 patients (59.8% male, 35.2% obese) requiring mechanical ventilation were assessed prospectively. REE measurements suggest a gradual increase of energy needs post 3rd day of ICU-S in both patients without obesity (non ob) ((from 17.8 kcal/kgr up to 29.3 kcal/kgr actual body weight (AcBW) during 28th day of ICU-S, p = 0.011)) and patients with obesity (ob) ((from 18.1 kcal/kgr up to 30.1 kcal/kgr adjusted body weight (AjBW) during 28th day of ICU-S, p = 0.021)). NMBAs use was accompanied by a significant drop in REE, especially during first 7 days of hospitalization, both in non ob (22.9 vs 17.9 kcal/kgr AcBW, p = 0.014) and ob patients (22.5 vs 19.5 kcal/kgr ABW, p = 0.027). Conclusion We identified the energy needs of COVID-19 intubated patients and highlighted a significant increase beyond the 1st week in the ICU. Administration of NMBAs should be considered, as it may impact resting energy expenditure.

Concurrent chemoradiotherapy (CCRT) is one of the most promising treatments for advanced head and neck cancer (HNC). On the other hand, CCRT may induce severe edema in laryngo-pharyngeal structures in association with radiation. This is a report of a 66-year-old man with severe obstructive sleep apnea (OSA) associated with edema in laryngo-hypopharynx after CCRT for advanced laryngeal and hypopharyngeal cancer. Tracheostomy was avoided and OSA was controlled by continuous positive airway pressure (CPAP). Subjective symptoms of sleepiness were improved. Though laryngeal edema appeared during the course of CCRT in this case, OSA was not evaluated until snoring had been pointed out and he complained of sleepiness. CCRT for laryngeal and hypopharyngeal cancer have a risk of occurrence of OSA due to irreversible mucous edema in the upper airway. Patients for whom CCRT is planned should be informed about the occurrence of OSA before the treatment because symptoms associated with OSA can negatively impact not only the daytime quality of life but also increase the risk of cardiovascular events. The OSA treatment for post CCRT would be expected to have a positive impact on not only cardiovascular and metabolic systems but also on the cancer treatment survival rate.

Summary Background & aims Sarcopenia, a loss of muscle mass, quality and function, which is particularly evident in respiratory muscles, has been associated with many clinical adverse outcomes. In this study, we aimed at evaluating the role of reduced muscle mass and quality in predicting ventilation weaning, complications, length of intensive care unit (ICU) and of hospital stay and mortality in patients admitted to ICU for SARS-CoV-2-related pneumonia. Methods This was an observational study based on a review of medical records of all adult patients admitted to the ICU of a tertiary hospital in Milan and intubated for SARS-CoV-2-related pneumonia during the first wave of the COVID-19 pandemic. Muscle mass and quality measurement were retrieved from routine thoracic CT scans, when sections passing through the first, second or third lumbar vertebra were available. Results A total of 81 patients were enrolled. Muscle mass was associated with successful extubation (OR 1.02, 95% C.I. 1.00–1.03, p = 0.017), shorter ICU stay (OR 0.97, 95% C.I. 0.95–0.99, p = 0.03) and decreased hospital mortality (HR 0.98, 95% C.I. 0.96–0.99, p = 0.02). Muscle density was associated with successful extubation (OR 1.07, 95% C.I. 1.01–1.14; p = 0.02) and had an inverse association with the number of complications in ICU (Β −0.07, 95% C.I. −0.13 - −0.002, p = 0.03), length of hospitalization (Β −1.36, 95% C.I. −2.21 - −0.51, p = 0.002) and in-hospital mortality (HR 0.88, 95% C.I. 0.78–0.99, p = 0.046). Conclusions Leveraging routine CT imaging to measure muscle mass and quality might constitute a simple, inexpensive and powerful tool to predict survival and disease course in patients with COVID-19. Preserving muscle mass during hospitalisation might have an adjuvant role in facilitating remission from COVID-19.
