Background: Mobilization after emergency abdominal surgery is considered essential to facilitate rehabilitation and reduce postoperative complications. The aim of this study was to evaluate the feasibility of early intensive mobilization after acute high-risk abdominal (AHA) surgery. Methods: We conducted a nonrandomized, prospective feasibility trial of consecutive patients after AHA surgery at a university hospital in Denmark. The participants followed a predefined, interdisciplinary protocol for early intensive mobilization during the first 7 postoperative days (PODs) of their hospital admission. We evaluated feasibility in accordance with the percentage of patients who mobilized within 24 hours after surgery, mobilized at least 4 times per day and achieved daily goals of time out of bed and walking distance. Results: We included 48 patients with a mean age of 61 (standard deviation 17) years (48% female). Within 24 hours after surgery, 92% of the patients were mobilized and 82% or more were mobilized at least 4 times per day over the first 7 PODs. On PODs 1-3, 70%-89% of the participants achieved the daily goals of mobilization; participants still in hospital after POD 3 were less able to achieve the daily goals. Patient reported that the primary factors limiting their level of mobilization were fatigue, pain and dizziness. Participants not mobilized independently on POD 3 (28%) had significantly (p < 0.04) fewer hours out of bed (4 v. 8 h), were less able to achieve the goals of time out of bed (45% v. 95%) and walking distance (62% v. 94%) and had longer hospital stays (14 v. 6 d) than participants mobilized independently on POD 3. Conclusion: The early intensive mobilization protocol seems feasible for most patients after AHA surgery. For nonindependent patients, however, alternative mobilization strategies and goals should be investigated. Contexte: On considère essentiel de mobiliser les malades après une intervention abdominale urgente afin de faciliter leur réadaptation et de réduire le risque de complications postopératoires. Le but de cette étude était d'évaluer la faisabilité d'une mobilisation intensive précoce après une chirurgie abdominale urgente à haut risque. Méthodes: Nous avons procédé à un essai de faisabilité prospectif non randomisé auprès de malades consécutifs ayant subi une chirurgie abdominale urgente à haut risque dans un centre hospitalier universitaire du Danemark. Nous avons appliqué un protocole interdisciplinaire prédéfini pour une mobilisation intensive précoce pendant les 7 premiers jours postopératoires. Nous avons évalué la faisabilité en fonction du pourcentage de malades ayant été mobilisés au cours de 24 premières heures suivant la chirurgie, ayant été mobilisés au moins 4 fois par jour et ayant atteint les objectifs quotidiens fixés pour le temps passé hors du lit et une distance franchie en marchant. Résultats: Nous avons inclus 48 malades âgés en moyenne de 61 ans (écart-type 17; 48% de sexe féminin). Dans les 24 heures suivant la chirurgie, 92% des malades ont été mobilisés et 82% ou plus l'ont été au moins 4 fois par jour au cours des 7 premiers jours postopératoires. Aux jours postopératoires 1-3, 70%-89% des participants ont atteint les objectifs quotidiens de mobilisation; les malades encore hospitalisés 3 jours après l'intervention étaient moins en mesure d'atteindre les objectifs quotidiens. Aux dires des malades, les principaux facteurs ayant limité leur mobilisation étaient la fatigue, la douleur et les étourdissements. Les participants qui n'avaient pas bénéficié de l'intervention de mobilisation autonome au 3e jour postopératoire (28%) avaient passé une nombre d'heures significativement moindre (p [less than or equal to] 0,04) hors du lit (4 c. 8 h), étaient moins aptes à atteindre les objectifs en terme de temps passé hors du lit (45% c. 95%) et de distance parcourue en marchant (62% c. 94%), et leur séjour hospitalier a été plus long (14 c. 6 j) comparativement aux malades soumis à l'intervention de mobilisation autonome au 3e jour postopératoire. Conclusion : Le protocole de mobilisation intensive précoce semble faisable pour la plupart des malades après une chirurgie abdominale urgente à haut risque. Pour les malades non autonomes, toutefois, il faudra explorer d'autres stratégies de mobilisation et fixer d'autres objectifs., A cute high-risk abdominal (AHA) surgery (i.e., major emergency abdominal surgery for intestinal obstruction, perforated viscus or bowel ischemia) is associated with high risks of postoperative complication, death and prolonged [...]

Mobilisation difficulties, due to muscle weakness, and urinary retention are common reasons for prolonged admission following hip and knee arthroplasty procedures. Whether spinal anaesthesia is detrimental to early mobilisation is controversial. Previous studies have reported differences in post‐operative recovery between spinal anaesthesia and general anaesthesia; however, up‐to‐date comparisons in fast‐track setups are needed. Our randomized, single‐blinded, multi‐centre, clinical trials aim to compare the post‐operative recovery after total hip (THA), total knee (TKA), and unicompartmental knee arthroplasties (UKA) respectively when using either spinal anaesthesia (SA) or general anaesthesia (GA) in a fast‐track setup. Included patients (74 THA, 74 TKA, and 74 UKA patients) are randomized (1:1) to receive either SA (2 mL 0.5% Bupivacaine) or GA (Induction: Propofol 1.0–2.0 mg/kg iv with Remifentanil 3–5 mcg/kg iv. Infusion: Propofol 3–5 mg/kg/h and Remifentanil 0.5 mcg/kg/min iv). Patients undergo standard primary unilateral hip and knee arthroplasty procedures in an optimized fast‐track setup with intraoperative local infiltrative analgesia in TKA and UKA, post‐operative multimodal opioid sparing analgesia, immediate mobilisation with full weightbearing, no drains and in‐hospital only thromboprophylaxis. Data will be collected on the day of surgery and until patients are discharged. The primary outcome is the ability to be safely mobilised during a 5‐m walking test within 6 h of surgery. Secondary outcomes include fulfilment of discharge criteria, post‐operative pain, dizziness, and nausea as well as patient reported recovery and opioid related side effects. Data will also be gathered on all hospital contacts within 30‐days of surgery. This study will offer insights into advantages and disadvantages of anaesthetic methods used in fast‐track arthroplasty surgery. [ABSTRACT FROM AUTHOR]

Background: This is Part 2 of the first consensus guidelines for optimal care of patients undergoing emergency laparotomy (EL) using an Enhanced Recovery After Surgery (ERAS) approach. This paper addresses intra- and postoperative aspects of care. Methods: Experts in aspects of management of high-risk and emergency general surgical patients were invited to contribute by the International ERAS® Society. PubMed, Cochrane, Embase, and Medline database searches were performed for ERAS elements and relevant specific topics. Studies on each item were selected with particular attention to randomized clinical trials, systematic reviews, meta-analyses, and large cohort studies and reviewed and graded using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. Recommendations were made on the best level of evidence, or extrapolation from studies on elective patients when appropriate. A modified Delphi method was used to validate final recommendations. Some ERAS® components covered in other guideline papers are outlined only briefly, with the bulk of the text focusing on key areas pertaining specifically to EL. Results: Twenty-three components of intraoperative and postoperative care were defined. Consensus was reached after three rounds of a modified Delphi Process. Conclusions: These guidelines are based on best available evidence for an ERAS® approach to patients undergoing EL. These guidelines are not exhaustive but pull together evidence on important components of care for this high-risk patient population. As much of the evidence is extrapolated from elective surgery or emergency general surgery (not specifically laparotomy), many of the components need further evaluation in future studies.

Background and purpose -- Day-case hip and knee arthroplasty has gained in popularity, but there are conflicting results regarding readmissions. We aimed to investigate differences in 30- and 90-day readmission rates between day-case patients and patients with a single overnight stay following primary total hip arthroplasty (THA), total knee arthroplasty (TKA), and unicompartmental knee arthroplasty (UKA). Patients and methods -- We identified day-case (DC) and overnight (ON) THA, TKA, and UKA patients, operated on between 2010 and 2020, from the Danish National Patient Register. Day-case surgery was defined as discharge on the day of surgery. Overnight readmissions within 30 or 90 days of surgery were considered readmissions. We compared readmission rates between DC and ON patients within arthroplasty types using logistic regression adjusted for patient characteristics and year of surgery. We included 29,486 THAs (1,353 DC and 28,133 ON), 15,116 TKAs (617 DC and 14,499 ON), and 6,440 UKAs (1,528 DC and 4,914 ON). Results -- The 30-day readmission rates were: DC-THA 4.4% vs. ON-THA 4.4% (adjusted odds-ratio [aOR] 1.2, 95% confidence interval [CI] 0.91-1.6), DC-TKA 4.7% vs. ON-TKA 4.4% (aOR 1.1, CI 0.69-1.5), and DC-UKA 3.0% vs. ON-UKA 3.0% (aOR 1.1, CI 0.78-1.5). Similarly, no significant differences were present between DC and ON THA, TKA, and UKA regarding 90-day readmissions or time to readmission. Conclusion -- We found no differences in readmission rates between day-case THA, TKA, and UKA patients and patients with a single overnight stay. [ABSTRACT FROM AUTHOR]

Background and purpose -- No previous studies have investigated the use of day-case arthroplasty in Denmark on a national scale. We investigated the frequency of day-case surgery in total hip (THA), total knee (TKA), and unicompartmental knee arthroplasty (UKA) from 2010 to 2020 in Denmark. Patients and methods -- Primary unilateral THAs, TKAs, and UKAs performed for osteoarthritis were identified in the Danish National Patient Register using procedural and diagnosis codes. Day-case surgery was defined as discharge on the day of surgery. 90-day readmissions were defined as any overnight admissions following discharge. Results -- From 2010 to 2020 Danish surgical centers performed 86,070 THAs, 70,323 TKAs, and 10,440 UKAs. From 2010 to 2014, less than 0.5% of THAs and TKAs were day-case procedures. They increased to 5.4% (95% confi- dence interval [CI] 4.9-5.8) of THAs and 2.8% (CI 2.4-3.2) of TKAs in 2019. From 2010 to 2014, 11% of UKAs were day-case procedures, but they increased to 20% (CI 18-22) in 2019. This increase was driven by a few surgical centers (3-7 centers). In 2010, readmission rates within 90 days of surgery were 10% after THAs and 11% after TKAs, and 9.4% for both THAs and TKAs in 2019. Readmission rates after UKA fluctuated between 4% and 7%. Conclusion -- From 2010 to 2020 the use of day-case surgery in THA, TKA, and UKA increased in Denmark, driven by only a few centers. During the same period readmissions did not increase.

New Findings: What is the topic of this review?Lactate is considered an important substrate for mitochondria in the muscles, heart and brain during exercise and is the main gluconeogenetic precursor in the liver and kidneys. In this light, we review the (patho)physiology of lactate metabolism in sepsis and coronavirus disease 2019 (COVID‐19).What advances does it highlight?Elevated blood lactate is strongly associated with mortality in septic patients. Lactate seems unrelated to tissue hypoxia but is likely to reflect mitochondrial dysfunction and high adrenergic stimulation. Patients with severe COVID‐19 exhibit near‐normal blood lactate, indicating preserved mitochondrial function, despite a systemic hyperinflammatory state similar to sepsis. In critically ill patients, elevated plasma lactate is often interpreted as a sign of organ hypoperfusion and/or tissue hypoxia. This view on lactate is likely to have been influenced by the pioneering exercise physiologists around 1920. August Krogh identified an oxygen deficit at the onset of exercise that was later related to an oxygen 'debt' and lactate accumulation by A. V. Hill. Lactate is considered to be the main gluconeogenetic precursor in the liver and kidneys during submaximal exercise, but hepatic elimination is attenuated by splanchnic vasoconstriction during high‐intensity exercise, causing an exponential increase in blood lactate. With the development of stable isotope tracers, lactate has become established as an important energy source for muscle, brain and heart tissue, where it is used for mitochondrial respiration. Plasma lactate > 4 mM is strongly associated with mortality in septic shock, with no direct link between lactate release and tissue hypoxia. Herein, we provide evidence for mitochondrial dysfunction and adrenergic stimulation as explanations for the sepsis‐induced hyperlactataemia. Despite profound hypoxaemia and intense work of breathing, patients with severe coronavirus disease 2019 (COVID‐19) rarely exhibit hyperlactataemia (> 2.5 mM), while presenting a systemic hyperinflammatory state much like sepsis. However, lactate dehydrogenase, which controls the formation of lactate, is markedly elevated in plasma and strongly associated with mortality in severe COVID‐19. We briefly review the potential mechanisms of the lactate dehydrogenase elevation in COVID‐19 and its relationship to lactate metabolism based on mechanisms established in contracting skeletal muscle and the acute respiratory distress syndrome.

Introduction: Existing multimodal pathways for patients undergoing acute high‐risk abdominal surgery for intestinal obstruction (IO) and perforated viscus (PV) have focused on rescue in the immediate perioperative period. However, there is little focus on the peri‐operative pathophysiology of recovery in this patient group, as done to develop enhanced recovery pathways in elective care. Acute inflammation is the main driver of the perioperative pathophysiology leading to adverse outcomes. Pre‐operative high‐dose of glucocorticoids provides a reduction in the inflammatory response after surgery, effective pain relief in several major surgical procedures, as well as reduce fatigue and improving endothelial dysfunction. Aim: To evaluate the effect of high‐dose glucocorticoid on the inflammatory response, fluid distribution and recovery after acute high‐risk abdominal surgery in patients with IO and PV. Methods: AHA STEROID trial is a sponsor‐initiated single‐center, randomized, double‐blind placebo‐controlled trial, assessing preoperative high‐dose dexamethasone (1 mg/kg) versus placebo (normal saline) in patients undergoing emergency high‐risk abdominal surgery. We plan to enroll 120 patients. Primary outcome is the reduction in C‐reactive protein on postoperative day 1 as a marker of successful attenuation of the acute stress response. Secondary outcomes include perioperative changes in endothelial and other inflammatory markers, fluid distribution, pulmonary function, pain, fatigue, and mobilization. The statistical plan is outlined in the protocol. Discussion: The AHA STEROID trial will provide important evidence to guide the potential use of high‐dose glucocorticoids in emergency high‐risk abdominal surgery, with respect to different pathophysiologies.

Background: Laparoscopic colorectal surgery requires perioperative positioning in the dorsal lithotomy position and intermittent Trendelenburg position. This position is associated with postoperative peripheral neuropathy (PPN), which is a substantial cause of anesthesia-related claims. The objective of this study was to assess the incidence of PPN of patients positioned in lithotomy position with shoulder braces, and second to compare this group with patients positioned on the foam mattress Pink Pad®. Materials and Methods: This consecutive single-center prospective cohort study of 155 patients undergoing colorectal surgery was performed between November 2014 and June 2015. After initial results the implementation of the Pink Pad took place and a total of 52 patients were included between May 2016 and February 2017 to compare the two groups. Results: Positioning with the shoulder brace regimen during laparoscopic colorectal surgery was related to the development of PPN in 33% of cases, as opposed to 15% with Pink Pad. Positioning with shoulder braces increased the risk of PPN with an odds ratio of 3.14 (95% confidence interval: 1.10-8.992) when compared with positioning on Pink Pad. Conclusion: Position-related PPN is an important complication after laparoscopic colorectal surgery. This study concludes that careful attention should be paid to positioning and favors Pink Pad over positioning with shoulder braces. Prolonged time in anesthesia is a predictor of PPN. Clinical Trial Number: H-2-2014-FSP75. [ABSTRACT FROM AUTHOR]

Introduction Perioperative haemodynamic instability is associated with postoperative morbidity and mortality. Macrocirculatory parameters, such as arterial blood pressure and cardiac output are associated with poor outcome but may be uncoupled from the microcirculation during sepsis and hypovolaemia and may not be optimal resuscitation parameters. The peripheral perfusion index (PPI) is derived from the pulse oximetry signal. Reduced peripheral perfusion is associated with morbidity in critically ill patients and in patients following acute surgery. We hypothesise that a low intraoperative PPI is independently associated with postoperative complications and mortality. Methods and analysis We plan to conduct a retrospective cohort study in approximately 2300 patients, who underwent acute non-cardiac surgery (1 November 2017 to 31 October 2018) at two Danish University Hospitals. Data will be collected from patient records including patient demographics, comorbidity and intraoperative haemodynamic values with PPI as the primary exposure variable, and postoperative complications and mortality within 30 and 90 days as outcome variables. We primarily assess association between PPI and outcome in multivariate regression models. Second, the predictive value of PPI for outcome, using area under the receiver operating characteristics curve is assessed. Ethics and dissemination Data will be reported according to the Strengthening the Reporting of Observational Studies in Epidemiology and results published in a peer-reviewed journal. The study is approved by the regional research ethics committee, storage and management of data has been approved by the Regional Data Protection Agency, and access to medical records is approved by the hospital board of directors ( ClinicalTrials. gov registration no: NCT03757442).
