Our aim was to determine the agreement of heart rate (HR) and respiratory rate (RR) measurements by the Philips Biosensor with a reference monitor (General Electric Carescape B650) in severely obese patients during and after bariatric surgery. Additionally, sensor reliability was assessed. Ninety-four severely obese patients were monitored with both the Biosensor and reference monitor during and after bariatric surgery. Agreement was defined as the mean absolute difference between both monitoring devices. Bland Altman plots and Clarke Error Grid analysis (CEG) were used to visualise differences. Sensor reliability was reflected by the amount, duration and causes of data loss. The mean absolute difference for HR was 1.26 beats per minute (bpm) (SD 0.84) during surgery and 1.84 bpm (SD 1.22) during recovery, and never exceeded the 8 bpm limit of agreement. The mean absolute difference for RR was 1.78 breaths per minute (brpm) (SD 1.90) during surgery and 4.24 brpm (SD 2.75) during recovery. The Biosensor’s RR measurements exceeded the 2 brpm limit of agreement in 58% of the compared measurements. Averaging 15 min of measurements for both devices improved agreement. CEG showed that 99% of averaged RR measurements resulted in adequate treatment. Data loss was limited to 4.5% of the total duration of measurements for RR. No clear causes for data loss were found. The Biosensor is suitable for remote monitoring of HR, but not RR in morbidly obese patients. Future research should focus on improving RR measurements, the interpretation of continuous data, and development of smart alarm systems.

Accidental extubation in the prone position is a medical emergency in which quick and low resource demanding airway management is required. Regaining oxygenation is the primary goal, but sometimes intubation may be required to regain oxygenation. Blind intubation through an i-gel® (Intersurgical Ltd, Wokingham, Berkshire, UK) may be a quick and low resource demanding method. However, the success rate of the use of an i-gel as an intubation conduit in the prone position is unknown. This was a prospective study in patients scheduled for lumbar surgery. General anaesthesia was induced in the prone position and an i-gel was inserted. After successful ventilation, up to three attempts at intubation using a VivaSight-SL single-lumen tube (Ambu A/S, Ballerup, Denmark) were performed. The first attempt was blinded for the operator and the patient’s head was in a neutral position. The second attempt was blinded for the operator with the patient’s head rotated laterally. The third attempt was on-screen and allowed various manoeuvres to facilitate intubation. A success rate of 70% was deemed clinically acceptable. The study was terminated early after 14 subjects because the success rate of 70% was not achievable. However, ventilation using the i-gel in the prone position was successful in 13 patients (93%). Intubation was successful in only one patient at the first attempt, one patient at the second attempt and three patients at the third attempt. Overall, the success rate was 36%. Blind intubation using an i-gel as an intubation conduit in the prone position is not recommended. Netherlands Trial Register number NL6387 (NTR7659).

Background Intrathecal hydrophilic opioids decrease systemic opioid consumption after abdominal surgery and potentially facilitate enhanced recovery. A meta-analysis is needed to quantify associated risks and benefits. Methods A systematic search was performed to find RCTs investigating intrathecal hydrophilic opioids in abdominal surgery. Caesarean section and continuous regional or neuraxial techniques were excluded. Several subgroup analyses were prespecified. A conventional meta-analysis, meta-regression, trial sequential analysis, and provision of GRADE scores were planned. Results The search yielded 40 trials consisting of 2500 patients. A difference was detected in ‘i.v. morphine consumption' at Day 1 {mean difference [MD] −18.4 mg, (95% confidence interval [CI]: −22.3 to −14.4)} and Day 2 (MD −25.5 mg [95% CI: −30.2 to −20.8]), pain scores at Day 1 in rest (MD −0.9 [95% CI: −1.1 to −0.7]) and during movement (MD −1.2 [95% CI: −1.6 to −0.8]), length of stay (MD −0.2 days [95% CI: −0.4 to −0.1]) and pruritus (relative risk 4.3 [95% CI: 2.5–7.5]) but not in nausea or sedation. A difference was detected for respiratory depression (odds ratio 5.5 [95% CI: 2.1–14.2]) but not when two small outlying studies were excluded (odds ratio 1.4 [95% CI: 0.4–5.2]). The level of evidence was graded as high for morphine consumption, in part because the required information size was reached. Conclusions This study showed important opioid-sparing effects of intrathecal hydrophilic opioids. Our data suggest a dose-dependent relationship between the risk of respiratory depression and the dose of intrathecal opioids. Excluding two high-dose studies, intrathecal opioids have a comparable incidence of respiratory depression as the control group. Clinical trial registration PROSPERO-registry: CRD42018090682.

OBJECTIVES: The ratio between PaO2 and FIO2 is used as a marker for impaired oxygenation and acute respiratory distress syndrome classification. However, any discrepancy between FIO2 and O2 fraction in the alveolus affects the PaO2/FIO2 ratio. Correcting the PaO2/FIO2 ratios using the alveolar gas equation may result in an improved reflection of the pulmonary situation. This study investigates the difference between standard and corrected PaO2/FIO2 in magnitude, its correlation with the mortality of acute respiratory distress syndrome classification, and trends over time.DESIGN: A register and a retrospective study combined with the development of a mathematical model to determine the difference between standard and corrected PaO2/FIO2 ratio for various levels of PaCO2 and atmospheric pressure.SETTING: ICU in a secondary hospital in the Netherlands.PATIENTS: Patients admitted to the ICU for pneumonia or acute respiratory distress syndrome. Register cohort: January 1, 2010, till March 1, 2020 (n = 1008). Retrospective cohort: March 1, 2020, till June 1, 2020 (n = 34).MEASUREMENTS AND MAIN RESULTS: The register was used to determine the 7-day ICU mortality per acute respiratory distress syndrome classification based on the standard and corrected PaO2/FIO2 ratio. The retrospective dataset correlated the PaCO2 with PaO2/FIO2 ratio over time in patients with assumed stable oxygenation. The model demonstrated an increased difference between the standard and corrected PaO2/FIO2 ratios by a lower FIO2 and atmospheric pressure and higher PaO2 and PaCO2. Reclassification of severe acute respiratory distress syndrome resulted in an increase in mortality from 28.1% for standard PaO2/FIO2 to 30.6% for corrected PaO2/FIO2 ratios. Acute Physiology and Chronic Health Evaluation scores correlated better with 7-day ICU-mortality when corrected PaO2/FIO2 ratio was used for classification. For patients with FIO2 less than 50% (n = 55), change in PaCO2 correlated with change in PaO2/FIO2 ratio (r = -0.388; p = 0.003).INTERVENTIONS: A corrected PaO2/FIO2 ratio was calculated.CONCLUSIONS: Correcting the PaO2/FIO2 ratio for the alveolar gas equation predominantly affects patients with high ratios between PaO2 and FIO2 and PaCO2 and at low atmospheric pressure. Using the corrected PaO2/FIO2 ratio for acute respiratory distress syndrome classification results in improved correlation with the 7-day ICU mortality and increases generalization among acute respiratory distress syndrome studies.

Purpose This study aims to investigate mortality and renal recovery in patients with Acute Kidney Injury (AKI) and Renal Replacement Therapy (RRT) due to COVID-19. A secondary aim is to investigate the filter life time in Continuous VenoVenous Hemofiltration (CVVH) and the effect of different methods of anticoagulation. Methods All patients with COVID-19 infection admitted to the ICU between March 16th 2020 to May 10th 2020 were retrospectively studied. Patients were categorized in a AKI-group and a non-AKI-group. Results Thirty-seven patients were included. Twenty-two (60%) patients developed AKI. Mortality in the AKI-group was 41% compared to 20% in the non-AKI group, p = 0.275. Comparable mortality was seen in the RRT (39%) and the non-RRT group (44%), p = 1.000. Renal function recovered to a KDIGO-stage 1 in 64% of the patients with AKI when discharged from the ICU. Life time for the CVVH filters (n = 53) was 27 h (14–63)[2–78]. No difference was found with various methods of anticoagulation. Conclusion The need for RRT in critically ill patients with COVID-19 was reversible in our cohort and RRT was not associated with an increased mortality compared to AKI without the need for RRT. Higher levels of anticoagulation were not associated with prolonged filter life.

Background: Delirium is a common complication after proximal femoral fracture surgery, with pain and opioid consumption as the contributing factors. The administration of intrathecal morphine may decrease these factors postoperatively and potentially reduce delirium. Objectives: This research aimed to study the association between the use of intrathecal morphine and the occurrence of delirium. Methods: A retrospective analysis of a prospective register kept in a non-academic hospital in the Netherlands was performed. The register contained data of all patients with proximal femur fractures that were surgically treated with osteosynthesis or prosthesis. Patients receiving spinal anesthesia (SA group) were compared with patients receiving spinal anesthesia with the addition of intrathecal morphine (SIM group). The administration of either SA or SIM was based on the preference of the anesthesiologist. The primary outcome was the incidence of delirium, as defined by the DSM-V classification. The follow-up lasted until hospital discharge. Both univariate and multivariate analyses were performed. Results: The SA group consisted of 451 patients, and the SIM group included 34 patients. Delirium occurred in 19.7% in the SA group versus 5.9% in the SIM group (P = 0.046). This association remained significant after correction in multivariate analysis (OR of delirium in the SA group, 95% CI: 1.062 - 21.006, P = 0.041). Additionally, multivariate analysis revealed that age, gender, preoperative cognitive impairment, and fracture treatment (osteosynthesis or prosthesis) were independently associated with delirium. Conclusions: This retrospective study found an independent association between the use of intrathecal morphine and a lower incidence of delirium. This clinically relevant decrease in delirium should be studied in a prospective randomized study.

Background Low concentrations of morphine are required for safe dosing for intrathecal injections. Sometimes, manual dilution of morphine is performed to achieve these low concentrations, but risks dilution errors and bacterial contamination. The primary goal was to compare the concentrations of morphine and bupivacaine between four groups of syringes. The secondary goal was to investigate the difference in contamination rate between these groups. Methods Twenty-five experienced anesthesia providers were asked to prepare a mixture of bupivacaine 2.0 mg/ml and morphine 60 μg/ml using 3 different methods as clean and precise as possible. The fourth method used was the aspiration of ampoules prepared by the pharmacy. The concentrations of morphine and bupivacaine were measured by High-Pressure Liquid Chromatography (HPLC). The medication was cultured for bacterial contamination. Results Group 1 (median 60 μg/ml; 95% CI: 59–110 μg/ml) yielded 3 outliers above 180 μg/ml morphine concentration. Group 2 (76 μg/ml; 95% CI: 72–80 μg/ml) and 3 (69 μg/ml; 95% CI: 66–71 μg/ml) were consistently higher than the target concentration of 60 μg. The group “pharmacy” was precise and accurate (59 μg/ml; 95% CI: 59–59 μg/ml). Group 2 and “pharmacy” had one contaminated sample with a spore-forming aerobic gram-positive rod. Conclusion Manually diluted morphine is at risk for deviating concentrations, which could lead to increased side-effects. Medication produced by the hospital pharmacy was highly accurate. Furthermore, even when precautions are undertaken, contamination of the medication is a serious risk and appeared to be unrelated to the dilution process.

Summary Robot‐assisted radical prostatectomy causes discomfort in the immediate postoperative period. This randomised controlled trial investigated if intrathecal bupivacaine/morphine, in addition to general anaesthesia, could be beneficial for the postoperative quality of recovery. One hundred and fifty‐five patients were randomly allocated to an intervention group that received intrathecal 12.5 mg bupivacaine/300 μg morphine (20% dose reduction in patients > 75 years) or a control group receiving a subcutaneous sham injection and an intravenous loading dose of 0.1 mg.kg−1 morphine. Both groups received standardised general anaesthesia and the same postoperative analgesic regimen. The primary outcome was a decrease in the Quality of Recovery‐15 (QoR‐15) questionnaire score on postoperative day 1. The intervention group (n = 76) had less reduction in QoR‐15 on postoperative day 1; median (IQR [range]) 10% (1–8 [−60% to 50%]) vs. 13% (5–24 [−6% to 50%]), p = 0.019, and used less morphine during the admission; 2 mg (1–7 [0–41 mg]) vs. 15 mg (12–20 [8–61 mg]), p

Background and Objectives Management of postoperative pain after laparoscopic segmental colonic resections remains controversial. We compared 2 methods of analgesia within an Enhanced Recovery After Surgery (ERAS) program. The goal of the study was to investigate whether administration of intrathecal bupivacaine/morphine would lead to an enhanced recovery. Methods A single-center, randomized, double-blind controlled trial was performed (NL43488.101.13). Patients scheduled for laparoscopic segmental intestinal resections were considered. Exclusion criteria were patients in whom contraindications to spinal anesthesia were present, conversion to open surgery, and gastric and rectal surgery. The intervention group received single-shot intrathecal bupivacaine/morphine (12.5 mg/300 μg), with an altered dose for older patients. The control group received a sham procedure and a bolus of piritramide (0.1 mg/kg). Both groups received standardized general anesthesia and a patient-controlled intravenous analgesia pump as postoperative analgesia. All patients were treated according to an ERAS protocol. A decrease in days to “fit for discharge” was the primary outcome. Results Fifty-six patients were enrolled. Intervention group patients were fit for discharge earlier (median of 3 vs 4 days, P = 0.044). Furthermore, there was a significant decrease in opioid use and lower pain scores on the first postoperative day in the intervention group. There were no differences in adverse events (except for more pruritus), time to mobilization, fluid administration, or patient satisfaction. Conclusions This randomized controlled trial shows that intrathecal morphine is a more effective method of postoperative analgesia in laparoscopic surgery than intravenous opioids within an ERAS program. Recovery is faster and less painful with intrathecal morphine. Other studies have confirmed these results, although data on faster recovery are new and require confirmation in future trials. Clinical Trial Registration This study was registered at ClinicalTrials.gov, identifier NCT02284282.

Context: Pathological changes secondary to degeneration of the cervical intervertebral disc may cause irritation of sympathetic nerve fibers, leading to sympathetic symptoms and tinnitus. Objectives: The aim of this study was to relate the effect of percutaneous radiofrequency treatment of superior cervical sympathetic ganglion in patients with tinnitus to cervical pathology. Method: A retrospective study of 74 consecutive patients who underwent treatment of the superior cervical sympathetic ganglion for tinnitus that persisted for 1 month or longer from October 2016 to January 2018. The work-up of a patient with tinnitus consisted of a standardized clinical history, a bilateral audiogram and a cervical spine radiograph. Results: All patients had a test blockade of superior cervical sympathetic ganglion first, and 54% of these patients (n=40) responded with a reduction of their tinnitus. These patients underwent a radiofrequency lesion and 53% (n=21) responded with a reduction of their tinnitus at 7 weeks following treatment. The size of anterior osteophyte at the fifth cervical vertebrae was related to a positive response at 7 weeks following this treatment. Patients with tinnitus and an anterior osteophyte at vertebrae C5 more than 17% of the width of those vertebrae had a success rate of 52% following treatment of the superior cervical sympathetic ganglion, compared to 13%, when the anterior osteophyte at C5 was 17% or less. Conclusions: The size of anterior cervical osteophytes is associated with a higher success rate of radiofrequency lesions of the superior sympathetic ganglion for tinnitus. The current results imply a role for cervical sympathetic nervous system irritation in the development of tinnitus in a subgroup of patients.

Background/Aims: In view of ongoing controversy, we wished to study whether patient characteristics and/or continuous venovenous hemofiltration (CVVH) characteristics contribute to the outcome of non-septic critically ill patients with acute kidney injury (AKI). Methods: We retrospectively studied 102 consecutive patients in the intensive care unit (ICU) with non-septic AKI needing CVVH. Patient and CVVH characteristics were evaluated. Primary outcome was mortality up to day 28 after CVVH initiation. Results: Forty-four patients (43%) died during the 28-day period after the start of CVVH. In univariate analyses, non-survivors had more often a cardiovascular reason for ICU admission, greater disease acuity/severity and organ failure, lower initial creatinine levels, less use of heparin and more use of bicarbonate-based substitution fluid. The latter two can be attributed to high lactate levels and bleeding tendency in non-survivors necessitating withholding lactate-buffered fluid and heparin, respectively, according to our clinical protocol. In multivariate analyses, mortality was predicted by disease severity, use of bicarbonate-based fluids and lack of heparin, while initial creatinine and CVVH dose did not contribute. Conclusion: The outcome of non-septic AKI in need of CVVH is more likely to be determined by underlying or concurrent, acute and severe disease rather than by CVVH characteristics, including timing and dose.

Purpose In continuous venovenous hemofiltration (CVVH) issues like timing and dose remain controversial, particularly in sepsis. The objective of this study is to examine which CVVH characteristic best predicts mortality in sepsis-induced acute kidney injury (AKI). Materials and Methods We retrospectively studied all consecutive patients with sepsis-induced AKI requiring CVVH in a 1.5-year period. Patient, sepsis, and CVVH characteristics, including timing, dose, mode, type of substitution fluid and of anticoagulation, and azotemic control were evaluated. Primary outcome was survival at day 28 after the start of CVVH. Results Of the 97 patients, 43 (44%) died up to day 28 after the start of CVVH. In univariate analyses, the delivered dose of CVVH was about 10% higher in survivors than nonsurvivors (median, 23 vs 20 mL kg −1 h −1 , P = .01). In multivariate analyses, a lower delivered CVVH dose contributed to predict higher mortality, independently of disease severity, type of substitution fluid, and azotemic control. In a Kaplan-Meier curve, a delivered dose less than 19.7 mL kg −1 h −1 was associated with shorter survival ( P = .006). Conclusion Our retrospective data suggest that in sepsis-induced AKI requiring CVVH, delivered dose, rather than timing, mode of administration, and azotemic control, is an independent predictor of mortality. A lower delivered dose is associated with higher mortality.

Introduction The objective of this study was to determine the long-term efficacy of percutaneous glycerol rhizolysis of the trigeminal ganglion for treating patients with trigeminal neuralgia and search for predictors associated with (long-term) benefit to improve patient selection. Methods A retrospective study in 60 consecutive patients treated with percutaneous glycerol rhizolysis of the trigeminal ganglion for trigeminal neuralgia. Charts were reviewed in combination with follow-up by questionnaire (n = 55, 92% response). Results Initial pain relief was achieved in 92% of the patients. Pain-free survival was 59% of the patients at 12 months and 53% at 24 months. Most common side effects were hypesthesia (15%), dry eye (5%), and meningitis (2%). In patients without involvement of the third branch of the trigeminal nerve, the initial effect was 79%, of which 90% achieved more than 2 years pain-free survival, compared with 97% initial effect and less than 40% pain-free survival of more than 2 years when the third trigeminal branch was involved. Discussion The present study demonstrates that involvement of the third branch is a negative predictor for long-term outcome in percutaneous glycerol rhizolysis of the trigeminal ganglion in patients with classical trigeminal neuralgia. However, in the absence of third-branch involvement, glycerol rhizolysis yields excellent long-term results when initial positive effect is obtained.

Introduction The objective of this study was to determine the efficacy of percutaneous radiofrequency (RF) treatment of the trigeminal ganglion for treating patients with trigeminal neuralgia, to determine which patients have a long-term benefit, and to evaluate the effect of RF parameters. Methods A retrospective study in 28 consecutive patients in combination with a follow-up questionnaire (n = 26, 93% response). Results An initial treatment effect of 89% was observed, 60% sustained at 12-month follow-up. Major side effects were hypesthesia (56%), dry eye (20%), and masseter muscle weakness (12%). A lower sensory stimulation threshold during treatment was associated with better patient satisfaction (P = 0.016), improved pain relief (P = 0.039), and trended toward more hypesthesia (P = 0.077). Discussion This low-volume study reported treatment effects in an older population that were similar to previous studies. Only a higher incidence of hypesthesia was detected by long-term follow-up. This study supported the high efficiency of RF treatment, but there was a high level of side effects. Most notable, low sensory stimulation was associated with increased hypesthesia, whereas higher stimulation levels yielded less effectiveness. Further investigation of an optimal sensory stimulation range for percutaneous RF treatment of the trigeminal ganglion was found to be warranted.

Introduction Rectal bleeding is a very common clinical sign. It is often caused by haemorrhoids. However, it can be a symptom of other pathology in the rectum or colon. There are little data coincidental pathology in patients with haemorrhoids and rectal bleeding. Objective To examine coincidental pathology in patients with rectal bleeding and haemorrhoids, especially with respect to age. Methods Prospectively, 290 consecutive patients presenting with bleeding and haemorrhoids were analysed. All patients had an endoscopic examination. All significant endoscopic findings (diverticuli, polyps, cancer, angiodysplasia and varices or colitis) were recorded. Results The patients were divided into two groups. Group 1 consisted of patients with only haemorrhoids (n = 129, % male: 41.1, mean age: 53.6 +/- 12.7 years). Group 2 consisted of patients with haemorrhoids and coincidental pathology (n = 161, % male: 46.6, mean age: 67.3 +/- 13.7 years). There was no difference in gender or in the type of endoscopy. However, patients in Group 2 were significantly older. Conclusion It can be concluded that in cases of rectal bleeding and haemorrhoids, coincidental pathology occurs in a large proportion of patients, especially the elderly. Omitting endoscopy in these patients can lead to major doctors delay.

Objectives: The objective of this case is to report the rare complication of a meningitis after an invasive treatment of the trigeminal ganglion. Methods: In this case report, two cases of meningitis due to oral streptococci are reported and a review of literature is presented. Results and Discussion: This complication should be recognized as early as possible to prevent deterioration of the situation. Meningitis must be suspected when a patient reports headache and fever within days after an invasive treatment of the trigeminal ganglion.

Background Haemorrhoids are a common problem in daily practice. However, symptoms may also be caused by other abnormalities in the rectum or colon. Data on the presence of these abnormalities in patients with haemorrhoids is sparse. To examine the prevalence of abnormalities of the colon or rectum in patients with and without haemorrhoids, stratified for age. Methods In a 17-year period 1910 consecutive patients with haemorrhoids and 7936 patients without haemorrhoids were analysed retrospectively. All of these patients had an endoscopic examination for different clinical reasons. All significant endoscopic co-findings (diverticuli, polyps, cancer, angiodysplasia and varices, or colitis) were recorded. Results The patients were divided in 2 groups. Group 1 (n = 861 (45.1%)) consisted of patients with only haemorrhoids, group 2 (n = 1049 (54.9%)) consisted of patients with haemorrhoids and another endoscopic diagnosis. Patients in group 1 were significantly younger, mean age 55.3 ± 14.1 years versus 67.4 ± 12.1 years (p < 0.001), and underwent significantly more often a sigmoidoscopy, 11% versus 2% (p < 0.0001). Furthermore, endoscopic co-findings were found with increasing age. The majority of diverticuli, polyps, cancer and vascular lesions were detected in the age group above 50 years, while only colitis was more often present in the younger group. There was no significant difference in gender when group 1 and 2 were compared with the reference group. Diverticuli and angiodysplasia/varices occurred significantly more often in group 2. The other significant diagnoses were diagnosed more often in the reference group. Conclusion In patients with haemorrhoids other abnormalities can be present. Especially in older patients the clinician must be cautious to attribute complaints solely to haemorrhoids.

Introduction: Stiff ears appear to be a warning sign for adrenal insufficiency. This remarkable and rare sign has not been described to present in adrenal insufficiency in the setting of critical care. Case presentation: We present the case of a 68-year-old Caucasian male who underwent a thymoma resection and suffered from preoperative weight loss and lack of strength. The perioperative phase was characterised by hypotension and sputum stasis due to muscle weakness, which caused two readmissions to the intensive care unit. His physical examination showed two fully rigid auricles. In retrospect, our patient suffered from secondary adrenal insufficiency and hypogonadism. Conclusions: The bilateral rigid auricles appeared to be a warning sign for adrenal insufficiency. This remarkable sign is easily checked, and should prompt a higher index of suspicion towards adrenal insufficiency and other hormonal deficiencies.
