Abstract
BACKGROUND Recommendations exist that aim to mitigate the substantial ecological impact of anaesthesia. One option is to use anaesthetic gas capturing technology at anaesthesia workstation exhausts to harvest and recycle volatile agents. However, the efficiency of such technology is mainly unverified in vivo. METHODS The efficiency of CONTRAfluran™ in capturing sevoflurane from an anaesthesia workstation exhaust (when set to minimal flow and end-tidal control mode) was evaluated in 70 adult patients scheduled for general or bariatric laparoscopic surgery. The weight of the sevoflurane vaporiser and CONTRAfluran canister was measured before and after each case, to calculate total sevoflurane consumption and retention. Retention was measured after the minimal flow maintenance phase and after the high flow washout phase. The total retention efficiency was the fraction of all consumed sevoflurane captured by the CONTRAfluran canister. The primary objective was to examine the retention efficiency of CONTRAfluran in a clinical surgical setting, where all feasible strategies to minimise sevoflurane consumption and optimise the efficacy of CONTRAfluran were utilised. The secondary objective was to analyse the correlation between mass transfer and the duration of the case. RESULTS Mean (SD) volume of sevoflurane captured using CONTRAfluran was 4.82 (1.41) ml, representing 45% (95%CI 42-48%) of all sevoflurane administered. The highest amount of retention was found during the washout phase. Retention efficiency did not correlate with the duration of the case. CONCLUSIONS Over half of the sevoflurane administered was not captured by the CONTRAfluran canister when minimal flow techniques were used, likely due to residual accumulation of sevoflurane in the patient after tracheal extubation or, to a lesser extent, due to ventilation system leakage. However, as every prevented emission is commendable, CONTRAfluran may be a potentially valuable tool for reducing the environmental footprint of sevoflurane-based anaesthesia.

Abstract
Remimazolam, a short-acting benzodiazepine, may be used for induction and maintenance of total intravenous anaesthesia, but its role in the management of patients with multiple comorbidities remains unclear. In this phase 3 randomised controlled trial, we compared the anaesthetic efficacy and the incidence of postinduction hypotension during total intravenous anaesthesia with remimazolam vs. propofol. A total of 365 patients (ASA physical status 3 or 4) scheduled for elective surgery were assigned randomly to receive total intravenous anaesthesia with remimazolam (n = 270) or propofol (n = 95). Primary outcome was anaesthetic effect, quantified as the percentage of time with Narcotrend® Index values ≤ 60, during surgery (skin incision to last skin suture), with a non-inferiority margin of -10%. Secondary outcome was the incidence of postinduction hypotensive events. Mean (SD) percentage of time with Narcotrend Index values ≤ 60 during surgery across all patients receiving remimazolam (93% (20.7)) was non-inferior to propofol (99% (4.2)), mean difference (97.5%CI) -6.28% (-8.89-infinite); p = 0.003. Mean (SD) number of postinduction hypotension events was 62 (38.1) and 71 (41.1) for patients allocated to the remimazolam and propofol groups, respectively; p = 0.015. Noradrenaline administration events (requirement for a bolus and/or infusion) were also lower in patients allocated to remimazolam compared with propofol (14 (13.5) vs. 20 (14.6), respectively; p < 0.001). In conclusion, in patients who were ASA physical status 3 or 4, the anaesthetic effect of remimazolam was non-inferior to propofol.

Association between improved compliance with enhanced recovery after cardiac surgery guidelines and postoperative outcomes: A retrospective study. J Thorac Cardiovasc Surg 2024; 167:1363-1371.e2. [PMID: 35989120 DOI: 10.1016/j.jtcvs.2022.07.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 06/23/2022] [Accepted: 07/06/2022] [Indexed: 11/19/2022]
Abstract
OBJECTIVE Enhanced recovery after cardiac surgery is a multidisciplinary clinical care pathway that relies on a bundle of interventions, aiming to reduce the stress response to surgery and promote early recovery of organ function. In 2011, our institution introduced an institutional enhanced recovery after cardiac surgery program focusing on 9 central interventions, which have been expanded during the past decade by additional interventions now considered standard of care. After the recent publication of the enhanced recovery after cardiac surgery guidelines, we evaluated the relation between the compliance with these enhanced recovery after cardiac surgery guidelines and postoperative outcomes. METHODS All patients enrolled in our enhanced recovery after cardiac surgery program in 2019 were included in this retrospective single-center audit. The primary outcome was compliance with 23 enhanced recovery after cardiac surgery guidelines. Secondary outcomes included occurrence of at least 1 postoperative complication and hospital length of stay. RESULTS A total of 356 patients were included in this study. Compliance with the enhanced recovery after cardiac surgery guidelines was 64%. Postoperatively, 51% of the patients experienced at least 1 complication and had a median hospital length of stay of 6 days. Multivariable analysis showed that an increased compliance (per 10%) with the enhanced recovery after cardiac surgery guidelines was associated with a lower risk for any complication (odds ratio, 0.60; 95% confidence interval, 0.46-0.79; P = .0003) and a higher probability of earlier hospital discharge (hazard ratio, 1.25; 95% confidence interval, 1.10-1.43; P = .0008). CONCLUSIONS This audit revealed a correlation between increased compliance with enhanced recovery after cardiac surgery guidelines and a reduction of postoperative complications and hospital length of stay. Future trials are needed to establish evidence-based recommendations for each separate intervention of the enhanced recovery after cardiac surgery guidelines and to create a minimum core-set of enhanced recovery after cardiac surgery interventions.

Abstract
We investigated the efficacy and safety of a bilateral anterior quadratus lumborum block in patients undergoing minimally invasive colorectal surgery. This was a two-centre, double-blind, prospective, randomised, placebo-controlled trial including 150 patients undergoing laparoscopic colorectal surgery (left- or right hemicolectomy, sigmoidectomy) who were enrolled in the institutional abdominal enhanced recovery programme. Before induction of anaesthesia, patients received a bilateral anterior quadratus lumborum block in the left and right lateral decubitus position under ultrasound guidance and were allocated randomly to receive 30 ml of ropivacaine 0.375% (n = 75) or placebo (saline 0.9%) (n = 75) bilaterally. Postoperatively, all patients received multimodal intravenous analgesia including paracetamol, ketorolac and patient-controlled analgesia with morphine. The primary outcome was morphine consumption during the first 24 h after tracheal extubation. Secondary outcomes included severity of pain; presence and extent of sensory block; incidence of postoperative nausea and vomiting; and hospital duration of stay. We also investigated the need for, and dose of, rescue analgesia. Safety outcomes included the incidence of adverse events. Mean (SD) 24-hour morphine consumption was no different between patients allocated to ropivacaine and placebo (28.6 (22.3) mg vs. 28.4 (22.5) mg, p = 0.966, respectively). While a sensory block could be detected in significantly more patients allocated to the ropivacaine group, no differences were detected in pain scores or other secondary or safety endpoints. Patient satisfaction scores were high in both groups. In laparoscopic colorectal surgery, adding a bilateral anterior quadratus lumborum block to a standard multimodal analgesia regimen did not reduce opioid consumption or improve pain scores.

Abstract
OBJECTIVES To estimate the current practice in the perioperative management of patients undergoing cardiac surgery due to infective endocarditis. DESIGN A prospective, open, 24-item, web-based cross-sectional survey. SETTING Online survey endorsed by the European Association of Cardiothoracic Anesthesiology and Intensive Care (EACTAIC). PARTICIPANTS Members of the EACTAIC. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS A total of 156 responses from 44 countries were received, with a completion rate of 99%. The response rate was 16.6%. Most respondents (76%) practiced cardiac anesthesia in European hospitals, and most respondents stated that a multidisciplinary endocarditis team was not established at their center, that cardiac anesthesiologists appeared to be involved infrequently in those teams (36%), and that they were not involved in decision-making on indication and timing of surgery (88%). In contrast, the cardiac anesthesiologist performed intraoperative antibiotic therapy (62%) and intraoperative transesophageal echocardiography (90%). Furthermore, there was a relative heterogeneity concerning perioperative monitoring, as well as for coagulation and transfusion management. CONCLUSIONS This international survey evaluated current practice among cardiac anesthesiologists in the perioperative management of patients with infective endocarditis and the anesthesiologist's role in multidisciplinary decision-making. Heterogeneity in treatment approaches was identified, indicating relevant knowledge gaps that should encourage further clinical research to optimize treatment and postoperative outcomes in this specific population.

Abstract
The number of patients with congenital heart disease (CHD) undergoing ambulatory surgery is increasing. Deciding whether a CHD patient is suitable for an ambulatory procedure is still challenging. Several factors must be considered, including the type of planned procedure, the complexity of the underlying pathology, the American Society of Anesthesiologists' Physical Status classification of the patient, and other patient-specific factors, including comorbidity, chronic complications of CHD, medication, coagulation disorders, and issues related to the presence of a pacemaker (PM) or cardioverter-defibrillator. Numerous studies reported higher perioperative mortality and morbidity rates in surgical patients with CHD than non-CHD patients. However, most of these studies were conducted in a cohort of hospitalized patients and may not reflect the ambulatory setting. The current review aims to provide the anesthesiologist with an overview and practical recommendations on selecting and managing a CHD patient scheduled for an ambulatory procedure.

Abstract
STUDY OBJECTIVE To investigate if an erector spinae plane (ESP) block decreases postoperative opioid consumption, pain and postoperative nausea and vomiting in patients undergoing robotically-assisted minimally invasive direct coronary artery bypass surgery (RAMIDCAB). DESIGN A single-center, double-blind, prospective, randomized, placebo-controlled trial. SETTING Postoperative period; operating room, post-anesthesia care unit (PACU) and hospital ward in a university hospital. PATIENTS Sixty-four patients undergoing RAMIDCAB surgery via left-sided mini-thoracotomy and enrolled in the institutional enhanced recovery after cardiac surgery program. INTERVENTIONS At the end of surgery, patients received an ESP catheter at vertebra T5 under ultrasound guidance and were randomized to the administration of either ropivacaine 0.5% (loading dose of 30 ml and three additional doses of 20 ml each, interspersed with a 6 h interval) or normal saline 0.9% (with an identical administration scheme). In addition, patients received multimodal analgesia including acetaminophen, dexamethasone and patient-controlled analgesia with morphine. Following the final ESP bolus and before catheter removal, the position of the catheter was re-evaluated by ultrasound. Patients, investigators and medical personnel were blinded for the group allocation during the entire trial. MEASUREMENTS Primary outcome was cumulative morphine consumption during the first 24 h after extubation. Secondary outcomes included location and severity of pain, presence/extent of sensory block, duration of postoperative ventilation and hospital length of stay. Safety outcomes comprised the incidence of adverse events. MAIN RESULTS Median (IQR) 24-h morphine consumption was not different between the intervention- and control-groups, 67 mg (35-84) versus 71 mg (52-90) (p = 0.25), respectively. Likewise, no differences were detected in secondary and safety endpoints. CONCLUSIONS Following RAMIDCAB surgery, adding an ESP block to a standard multimodal analgesia regimen did not reduce opioid consumption and pain scores.

Abstract
PURPOSE Perioperative pulmonary hypertension (PH) is an independent risk factor for morbidity and mortality in cardiac surgery. While inhaled prostacyclins (iPGI2s) are an established treatment of chronic PH, data on the efficacy of iPGI2s in perioperative PH are scarce. METHODS We searched PubMed, Embase, the Web of Science, CENTRAL, and the grey literature from inception until April 2021. We included randomized controlled trials investigating the use of iPGI2s in adult and pediatric patients undergoing cardiac surgery with an increased risk of perioperative right ventricle failure. We assessed the efficacy and safety of iPGI2s compared with placebo and other inhaled or intravenous vasodilators with random-effect meta-analyses. The primary outcome was mean pulmonary artery pressure (MPAP). Secondary outcomes included other hemodynamic parameters and mortality. RESULTS Thirteen studies were included, comprising 734 patients. Inhaled prostacyclins significantly decreased MPAP compared with placebo (standardized effect size, 0.46; 95% confidence interval [CI], 0.11 to 0.87; P = 0.01) and to intravenous vasodilators (1.26; 95% CI, 0.03 to 2.49; P = 0.045). Inhaled prostacyclins significantly improved the cardiac index compared with intravenous vasodilators (1.53; 95% CI, 0.50 to 2.57; P = 0.004). In contrast, mean arterial pressure was significantly lower in patients treated with iPGI2s vs placebo (-0.39; 95% CI, -0.62 to 0.16; P = 0.001), but higher than in patients treated with intravenous vasodilators (0.81; 95% CI, 0.29 to 1.33; P = 0.002). With respect to hemodynamics, iPGI2s had similar effects as other inhaled vasodilators. Mortality was not affected by iPGI2s. CONCLUSION The results of this systematic review and meta-analysis show that iPGI2s improved pulmonary hemodynamics with similar efficacy as other inhaled vasodilators, but caused a significant small decrease in arterial pressure when compared with placebo, indicating spill-over into the systemic circulation. These effects did not affect clinical outcomes. STUDY REGISTRATION DATE PROSPERO (CRD42021237991); registered 26 May 2021.

High-volume patient-controlled epidural vs. programmed intermittent epidural bolus for labour analgesia: a randomised controlled study. Anaesthesia 2023.

Abstract
The aim of neuraxial analgesia is to achieve excellent pain relief with the fewest adverse effects. The most recently introduced technique for epidural analgesia maintenance is the programmed intermittent epidural bolus. In a recent study, we compared this with patient-controlled epidural analgesia without a background infusion and found that a programmed intermittent epidural bolus was associated with less breakthrough pain, lower pain scores, higher local anaesthetic consumption and comparable motor block. However, we had compared 10 ml programmed intermittent epidural boluses with 5 ml patient-controlled epidural analgesia boluses. To overcome this potential limitation, we designed a randomised, multicentre non-inferiority trial using 10 ml boluses in each group. The primary outcome was the incidence of breakthrough pain and total analgesic intake. Secondary outcomes included motor block; pain scores; patient satisfaction; and obstetric and neonatal outcomes. The trial was considered positive if two endpoints were met: non-inferiority of patient-controlled epidural analgesia with respect to breakthrough pain; and superiority of patient-controlled epidural analgesia with respect to local anaesthetic consumption. A total of 360 nulliparous women were allocated randomly to patient-controlled epidural analgesia-only or programmed intermittent epidural bolus groups. The patient-controlled group received 10 ml boluses of ropivacaine 0.12% with sufentanil 0.75 μg.ml-1 ; the programmed intermittent group received 10 ml boluses supplemented by 5 ml patient-controlled boluses. The lockout period was 30 min in each group and the maximum allowed hourly local anaesthetic/opioid consumption was identical between the groups. Breakthrough pain was similar between groups (11.2% patient controlled vs. 10.8% programmed intermittent, p = 0.003 for non-inferiority). Total ropivacaine consumption was lower in the PCEA-group (mean difference 15.3 mg, p < 0.001). Motor block, patient satisfaction scores and maternal and neonatal outcomes were similar across both groups. In conclusion, patient-controlled epidural analgesia is non-inferior to programmed intermittent epidural bolus if equal volumes of patient-controlled epidural analgesia are used to maintain labour analgesia and superior with respect to local anaesthetic consumption.

Abstract
STUDY OBJECTIVE To investigate if an erector spinae plane (ESP) block decreases postoperative opioid consumption, pain and postoperative nausea and vomiting in patients undergoing minimally invasive mitral valve surgery (MIMVS). DESIGN A single-center, double-blind, prospective, randomized, placebo-controlled trial. SETTING Postoperative period; operating room, post-anesthesia care unit (PACU) and hospital ward in a university hospital. PATIENTS Seventy-two patients undergoing video-assisted thoracoscopic MIMVS via right-sided mini-thoracotomy and enrolled in the institutional enhanced recovery after cardiac surgery program. INTERVENTIONS At the end of surgery, all patients received an ESP catheter at vertebra T5 under ultrasound guidance and were randomized to the administration of either ropivacaine 0.5% (loading of dose 30 ml and three additional doses of 20 ml with a 6 h interval) or normal saline 0.9% (with an identical administration scheme). In addition, patients received multimodal postoperative analgesia including dexamethasone, acetaminophen and patient-controlled intravenous analgesia with morphine. Following the final ESP bolus and before catheter removal, the position of the catheter was re-evaluated by ultrasound. Patients, investigators and medical personnel were blinded for the group allocation during the entire trial. MEASUREMENTS Primary outcome was cumulative morphine consumption during the first 24 h after extubation. Secondary outcomes included severity of pain, presence/extent of sensory block, duration of postoperative ventilation and hospital length of stay. Safety outcomes comprised the incidence of adverse events. MAIN RESULTS Median (IQR) 24-h morphine consumption was not different between the intervention- and control-group, 41 mg (30-55) versus 37 mg (29-50) (p = 0.70), respectively. Likewise, no differences were detected for secondary and safety endpoints. CONCLUSIONS Following MIMVS, adding an ESP block to a standard multimodal analgesia regimen did not reduce opioid consumption and pain scores.

Abstract
PURPOSE OF REVIEW Cardiovascular disease is increasingly emerging as a cause of peripartum morbidity and mortality. Peripartum cardiomyopathy (PPCM) is defined as pregnancy-related heart failure with a reduced left ventricular ejection fraction <45%. PPCM develops in the peripartum phase and is not an aggravation of an existing prepregnancy cardiomyopathy. Anesthesiologists typically encounter these patients in the peripartum phase in a variety of settings and should be aware of this pathology and its implications for the perioperative management of parturients. RECENT FINDINGS PPCM has been investigated increasingly over the last few years. Significant progress has been made in the assessment of global epidemiology, pathophysiological mechanisms, genetics and treatment. SUMMARY Although PPCM is an overall rare pathology, patients can potentially be encountered by any anesthesiologist in many different settings. Therefore, it is important to be aware of this disease and understand the basic implications for anesthetic management. Severe cases often require early referral to specialized centers for advanced hemodynamic monitoring and pharmacological or mechanical circulatory support.

Effects of cumulative duration of repeated anaesthesia exposure on foetal brain development in the ovine model. J Clin Anesth 2023; 85:111050. [PMID: 36640704 DOI: 10.1016/j.jclinane.2022.111050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Revised: 12/30/2022] [Accepted: 12/30/2022] [Indexed: 01/14/2023]
Abstract
OBJECTIVE Anaesthesia is required in 0.4-1% of pregnant women, and prolonged and repeated exposures to anaesthesia may be required. It is unknown whether these exposures may result in foetal neurotoxicity in humans. As sheep have a gestation comparable to that of humans, the objective of this study was to analyse the neurodevelopmental outcome of ovine foetuses that had been exposed in utero to repeated and prolonged anaesthesia. DESIGN Randomized controlled preclinical study. SETTING Anaesthesia for non-obstetric surgery during pregnancy. ANIMALS Twenty-four healthy pregnant Swifter ewes. INTERVENTIONS The ewes were randomized to no anaesthesia exposure (control-group), single exposure (at gestational age 68-70 days), or repeated exposure (at gestational age 68-70 days and 96-98 days) to 2.5 h of sevoflurane anaesthesia and maternal laparotomy. All lambs were delivered at approximately term gestation (gestational age: 140-143 days). MEASUREMENTS The primary outcome was neuron density in the frontal cortex 24 h after birth for the control-group versus the repeated-exposure-group. Key secondary outcome was the time needed to achieve the milestone of standing. Secondary outcomes included other neurobehavioural assessments (e.g., motoric milestones) and histological parameters quantified in multiple brain regions (neuron density, total cell density, proliferation, inflammation, synaptogenesis, astrocytes and myelination). MAIN RESULTS Neuron density in the frontal cortex did not differ between groups (mean ± standard deviation: control-group: 403 ± 39, single-exposure group: 436 ± 23 and repeated-exposure-group: 403 ± 40 neurons/mm2, control-group versus repeated-exposure-group: p = 0.986, control-group versus single-exposure-group: p = 0.097). No significant difference was observed for the time needed to achieve the milestone of standing. Only very limited differences were observed for other histological outcome parameters and neurobehavioural assessments. CONCLUSIONS There is no evidence for foetal neuronal injury or neurobehavioural impairments after a cumulative duration of 5 h repetitive prenatal anaesthesia in sheep.

Association between preoperative anxiety and postoperative delirium in older patients: a systematic review and meta-analysis. BMC Geriatr 2023; 23:198.

Abstract
BACKGROUND Postoperative delirium (POD) is a common postoperative complication associated with multiple adverse consequences on patient outcomes and higher medical expenses. Preoperative anxiety has been suggested as a possible precipitating factor for the development of POD. As such, we aimed to explore the association between preoperative anxiety and POD in older surgical patients. METHODS Electronic databases including MEDLINE (via PubMed), EMBASE (via Embase.com), Web of Science Core Collection, Cumulative Index to Nursing and Allied Health Literature (CINAHL Complete; via EBSCOhost) and clinical trial registries were systematically searched to identify prospective studies examining preoperative anxiety as a risk factor for POD in older surgical patients. We used Joanna Briggs Institute Critical Appraisal Checklist for Cohort Studies to assess the quality of included studies. The association between preoperative anxiety and POD was summarized with odds ratios (ORs) and 95% confidence intervals (CIs) using DerSimonian-Laird random-effects meta-analysis. RESULTS Eleven studies were included (1691 participants; mean age ranging between 63.1-82.3 years). Five studies used a theoretical definition for preoperative anxiety, with the Anxiety subscale of Hospital Anxiety and Depression Scale (HADS-A) as the instrument being most often used. When using dichotomized measures and within the HADS-A subgroup analysis, preoperative anxiety was significantly associated with POD (OR = 2.17, 95%CI: 1.01-4.68, I2 = 54%, Tau2 = 0.4, n = 5; OR = 3.23, 95%CI: 1.70-6.13, I2 = 0, Tau2 = 0, n = 4; respectively). No association was observed when using continuous measurements (OR = 0.99, 95%CI: 0.93-1.05, I2 = 0, Tau2 = 0, n = 4), nor in the subgroup analysis of STAI-6 (six-item version of state scale of Spielberger State-Trait Anxiety Inventory, OR = 1.07, 95%CI: 0.93-1.24, I2 = 0, Tau2 = 0, n = 2). We found the overall quality of included studies to be moderate to good. CONCLUSIONS An unclear association between preoperative anxiety and POD in older surgical patients was found in our study. Given the ambiguity in conceptualization and measurement instruments used for preoperative anxiety, more research is warranted in which a greater emphasis should be placed on how preoperative anxiety is operationalized and measured.

Brain development is altered in rabbit fetuses with congenital diaphragmatic hernia. Prenat Diagn 2023; 43:359-369.

Abstract
INTRODUCTION Children with congenital diaphragmatic hernia (CDH) are at risk for neurodevelopmental delay. Some changes are already present prenatally. Herein, we further examined how the brain develops in fetal rabbits with surgically created DH. METHODS Two fetuses underwent surgical DH creation on day 23 (term = d31). DH pups and littermate controls were harvested at term. Ten DH pups and 11 controls underwent transcardial perfusion for brain fixation and measurement of brain volume, brain folding, neuron and synaptic density, pre-oligodendrocyte count, proliferation, and vascularization. Twelve other DH and 11 controls had echocardiographic assessment of cardiac output and aortic and cerebral blood flow, magnetic resonance imaging (9.4 T) for cerebral volumetry, and molecular assessment of vascularization markers. RESULTS DH pups had lower lung-to-body weight ratio (1.3 ± 0.3 vs. 2.4 ± 0.3%; p < 0.0001) and lower heart-to-body weight ratio (0.007 ± 0.001 vs. 0.009 ± 0.001; p = 0.0006) but comparable body weight and brain-to-body weight ratio. DH pups had a lower left ventricular ejection fraction, aortic and cerebral blood flow (39 ± 8 vs. 54 ± 15 mm/beat; p = 0.03) as compared to controls but similar left cardiac ventricular morphology. Fetal DH-brains were similar in volume but the cerebellum was less folded (perimeter/surface area: 25.5 ± 1.5 vs. 26.8 ± 1.2; p = 0.049). Furthermore, DH brains had a thinner cortex (143 ± 9 vs. 156 ± 13 μm; p = 0.02). Neuron densities in the white matter were higher in DH fetuses (124 ± 18 vs. 104 ± 14; p = 0.01) with comparable proliferation rates. Pre-oligodendrocyte count was lower, coinciding with the lower endothelial cell count. CONCLUSION Rabbits with DH had altered brain development compared to controls prenatally, indicating that brain development is already altered prenatally in CDH.

Abstract
ABSTRACT Asystole presenting at the start of electrical stimulus application during electroconvulsive therapy (ECT) is a relatively common occurrence. It is most likely caused by vagal nerve stimulation, affecting autonomic cardiac tone. This article reviews the effect of the electrode placement (EP) on the incidence and severity of bradycardia and asystole. A systematic literature review was conducted using the Embase and PubMed databases, up to September 2021, searching for studies evaluating the effect of EP on bradycardia and/or asystole during ECT. Nine case reports describing asystole in patients receiving ECT almost exclusively reported the association with bitemporal (BT) EP. One small descriptive study found no significant effect of EP on cardiac pauses. The results from 4 cohort studies, however, suggest that a right unilateral placement bears a higher risk for developing bradycardia and asystole than BT and bifrontal ECT. The available evidence suggests that right unilateral ECT holds a greater risk for the development of bradycardia and asystole than BT and bifrontal EP.

Abstract
Up to 1% of pregnant women undergo anaesthesia for non-obstetric surgery. This study investigated neurodevelopmental outcomes after prenatal anaesthesia for maternal surgery. A bidirectional cohort study of children born between 2001 and 2018 was performed: neurodevelopmental outcomes of children who had received prenatal anaesthesia for maternal surgery were prospectively compared with unexposed children, with exposure status being assessed retrospectively. Children exposed to anaesthesia for obstetric and fetal surgery were excluded. The primary outcome was the global executive composite of the behaviour rating inventory of executive function score. Our secondary outcomes were: total problems; internalising problems and externalising problems derived from the child behaviour checklist; psychiatric diagnoses; and learning disorders. In 90% of exposed children, there was a single mean (SD) antenatal anaesthesia exposure lasting 91(94) min. There was a broad spectrum of indications, with abdominal surgery being most frequent. Parents of 129 exposed (response rate 68%) and 453 unexposed (response rate 63%) children participated. There were no arguments for non-response bias. After propensity weighting, there were no statistically significant differences in primary outcome, with a weighted mean difference (95%CI) of exposed minus unexposed children of 1.9 (-0.4-4.2), p = 0.10; or any of the secondary outcomes. Sensitivity analyses confirmed the robustness. Exploratory analyses, however, showed significant differences in certain subgroups for the primary outcome, (e.g. for intra-abdominal surgery, exposure duration > 1 h) and some cognitive subdomains (e.g. working memory and attention). This bidirectional cohort study, the largest investigation on the subject to date, has found no evidence in the general population for an association between prenatal exposure to anaesthesia and impaired neurodevelopmental outcomes.

Abstract
OBJECTIVES To optimize protamine titration for heparin antagonization after weaning from cardiopulmonary bypass (CPB). DESIGN A prospective, observational trial. SETTING Single-center, non-university teaching hospital. PARTICIPANTS Forty patients presenting for elective on-pump coronary artery bypass grafting with or without single valve surgery. INTERVENTIONS At the end of CPB, the residual amount of heparin in the patient was estimated using a Bull-curve. The total protamine dose was calculated as 1 unit of protamine for 1 unit of heparin. Protamine was administered as 5 aliquots containing 20% of the total protamine dose each, with 2-min intervals. MEASUREMENTS AND MAIN RESULTS Activated Clotting Time (ACT) values were measured 2 min after administration of each aliquot. ROTEM(®)-analysis was performed after the full dose of protamine had been administered. After 60% of the total protamine dose had been administered, ACT values were normalized in 86.5% of patients. After the complete dose of protamine had been administered, 61.1% of patients displayed signs of protamine overdose on ROTEM(®)-analysis. CONCLUSIONS In patients who present for on-pump coronary artery bypass grafting with or without single valve surgery, a 0.6-to-1 ratio of protamine-to-heparin to antagonize heparin may be sufficient and beneficial for patients.

Abstract
While euthanasia has been legalized in a growing number of countries, organ donation after euthanasia is only performed in Belgium, the Netherlands, Spain, and Canada. Moreover, the clinical practice of heart donation after euthanasia has never been reported before. We describe the first case of a heart donated after euthanasia, reconditioned with thoraco-abdominal normothermic regional perfusion, preserved using cold storage while being transported to a neighboring transplant center, and then successfully transplanted following a procurement warm ischemic time of 17 min. Heart donation after euthanasia using thoraco-abdominal normothermic regional perfusion is feasible, it could expand the heart donor pool and reduce waiting lists in countries where organ donation after euthanasia can be performed.

Abstract
WHAT IS KNOWN AND OBJECTIVE Emergent cardiac surgery in patients under anticoagulant therapy is still a major point of concern. Recently approved reversal agents are often not available or not suitable in the cardiac surgery setting, and timely discontinuation of the drug is not always feasible. CytoSorb® haemoadsorption therapy has been approved in Europe for intraoperative ticagrelor and rivaroxaban removal during cardiopulmonary bypass (CPB), but thus far the efficacy of CytoSorb® haemoadsorber on other anticoagulants (apixaban, dabigatran, edoxaban) has only been tested in vitro, and some signals of clinical benefits have reported in a few case reports. CASE SUMMARY We describe a case of CPB implementation with CytoSorb® in a haemodynamic unstable patient with prosthetic aortic valve endocarditis on apixaban therapy. WHAT IS NEW AND CONCLUSION CytoSorb® proved to be effective for removal of apixaban in emergency surgery setting by direct measurements of drug levels before and during CPB circulation.

Abstract
Brain tumour identification and delineation in a timeframe of seconds would significantly guide and support surgical decisions. Here, treatment is often complicated by the infiltration of gliomas in the surrounding brain parenchyma. Accurate delineation of the invasive margins is essential to increase the extent of resection and to avoid postoperative neurological deficits. Currently, histopathological annotation of brain biopsies and genetic phenotyping still define the first line treatment, where results become only available after surgery. Furthermore, adjuvant techniques to improve intraoperative visualisation of the tumour tissue have been developed and validated. In this review, we focused on the sensitivity and specificity of conventional techniques to characterise the tumour type and margin, specifically fluorescent-guided surgery, neuronavigation and intraoperative imaging as well as on more experimental techniques such as mass spectrometry-based diagnostics, Raman spectrometry and hyperspectral imaging. Based on our findings, all investigated methods had their advantages and limitations, guiding researchers towards the combined use of intraoperative imaging techniques. This can lead to an improved outcome in terms of extent of tumour resection and progression free survival while preserving neurological outcome of the patients.

Abstract
Background Thromboinflammation plays a central role in severe COVID-19. The kallikrein pathway activates both inflammatory pathways and contact-mediated coagulation. We investigated if modulation of the thromboinflammatory response improves outcomes in hospitalized COVID-19 patients. Methods In this multicenter open-label randomized clinical trial (EudraCT 2020-001739-28), patients hospitalized with COVID-19 were 1:2 randomized to receive standard of care (SOC) or SOC plus study intervention. The intervention consisted of aprotinin (2,000,000 IE IV four times daily) combined with low molecular weight heparin (LMWH; SC 50 IU/kg twice daily on the ward, 75 IU/kg twice daily in intensive care). Additionally, patients with predefined hyperinflammation received the interleukin-1 receptor antagonist anakinra (100 mg IV four times daily). The primary outcome was time to a sustained 2-point improvement on the 7-point World Health Organization ordinal scale for clinical status, or discharge. Findings Between 24 June 2020 and 1 February 2021, 105 patients were randomized, and 102 patients were included in the full analysis set (intervention N = 67 vs. SOC N = 35). Twenty-five patients from the intervention group (37%) received anakinra. The intervention did not affect the primary outcome (HR 0.77 [CI 0.50-1.19], p = 0.24) or mortality (intervention n = 3 [4.6%] vs. SOC n = 2 [5.7%], HR 0.82 [CI 0.14-4.94], p = 0.83). There was one treatment-related adverse event in the intervention group (hematuria, 1.49%). There was one thrombotic event in the intervention group (1.49%) and one in the SOC group (2.86%), but no major bleeding. Conclusions In hospitalized COVID-19 patients, modulation of thromboinflammation with high-dose aprotinin and LMWH with or without anakinra did not improve outcome in patients with moderate to severe COVID-19.

The use of cognitive aids in the operating room: a systematic review. ACTA ANAESTHESIOLOGICA BELGICA 2022. [DOI: 10.56126/73.3.18] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 12/05/2022]
Abstract
Background: Cognitive aids (CAs) are clinical tools guiding clinical decision-making during critical events in the operating room. They may counteract the adverse effects of stress on the non-technical skills of the attending clinician(s). Although most clinicians acknowledge the importance of CAs, their uptake in clinical practice seems to be lagging behind. This situation has led us to investigate which features of CAs may enhance their uptake. Therefore, in this systematic review we explored the optimums regarding the 1) timing to consult the CA, 2) person consulting the CA, 3) location of the CA in the operating room, 4) CA design (paper vs. electronic), 5) CA lay-out, 6) reader of the CA and 7) if the use of CAs in the form of decision support tools lead to improved outcome.
Methods: Seven PICO-questions guided our literature search in 4 biomedical databases (MEDLINE, Embase, Web of Science and Google Scholar). We selected English-language randomized controlled trials (RCTs), observational studies and expert opinions discussing the use of cognitive aids during life-threatening events in the operating theatre. Articles discussing non-urgent or non-operating room settings were excluded. The quality of evidence was evaluated with the Grading of Recommendations Assessment, Development and Evaluation (GRADE).
Results: We found 7 RCTs, 14 observational studies and 6 expert opinions. All trials were conducted in a simulation environment. The person who should trigger the use of a cognitive aid and the optimal timing of its initiation, could not be defined by the current literature. The ideal location of the cognitive aids remains also unclear.
A favorable lay-out of an aid should be well-structured, standardized and easily readable. In addition, several potentially beneficial design features are described.
RCT’s could not demonstrate a possible superiority of either electronic or paper-based aids. Both have their advantages and disadvantages. Furthermore, electronic decision support tools are potentially associated with an enhanced performance of the clinician. Likewise, the presence of a reader was associated with an improved performance of key steps in the management of a critical event. However, it remains unclear who should fulfill this role.
Conclusion: Several features of the design or utilization of CAs may play a role in enhancing the uptake of CAs in clinical practice during the management of a critical event in the operating room. However, robust evidence supporting the use of a certain feature over another is lacking.

The role of transesophageal echocardiography in guiding heart donation after circulatory death. Clin Transplant 2022; 36:e14783. [PMID: 35920407 DOI: 10.1111/ctr.14783] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2022] [Revised: 07/15/2022] [Accepted: 07/19/2022] [Indexed: 11/26/2022]
Abstract
Heart donation after circulatory death (DCD) can significantly expand the heart donor pool, helping to overcome the problem of organ shortage and the increase in waiting list mortality and morbidity. To improve the outcome of DCD heart transplantation, thoraco-abdominal normothermic regional perfusion (TA-NRP) can be performed by selectively restoring circulation followed by in vivo functional heart assessment. Here, we report on the use of periprocedural transoesophageal echocardiography (TOE) as a minimally invasive cardiac assessment tool during different stages of a DCD heart procurement procedure using TA-NRP. We conclude that TOE is a valuable method to assess the donor heart for transplantation eligibility before and after withdrawal of life-sustaining therapy and during subsequent TA-NRP.

How to implement geriatric co-management in your hospital? Insights from the G-COACH feasibility study. BMC Geriatr 2022; 22:386. [PMID: 35501840 PMCID: PMC9059346 DOI: 10.1186/s12877-022-03051-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 04/12/2022] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Geriatric co-management is advocated to manage frail patients in the hospital, but there is no guidance on how to implement such programmes in practice. This paper reports our experiences with implementing the 'Geriatric CO-mAnagement for Cardiology patients in the Hospital' (G-COACH) programme. We investigated if G-COACH was feasible to perform after the initial adoption, investigated how well the implementation strategy was able to achieve the implementation targets, determined how patients experienced receiving G-COACH, and determined how healthcare professionals experienced the implementation of G-COACH. METHODS A feasibility study of the G-COACH programme was performed using a one-group experimental study design. G-COACH was previously implemented on two cardiac care units. Patients and healthcare professionals participating in the G-COACH programme were recruited for this evaluation. The feasibility of the programme was investigated by observing the reach, fidelity and dose using registrations in the electronic patient record and by interviewing patients. The success of the implementation reaching its targets was evaluated using a survey that was completed by 48 healthcare professionals. The experiences of 111 patients were recorded during structured survey interviews. The experiences of healthcare professionals with the implementation process was recorded during 6 semi-structured interviews and 4 focus groups discussions (n = 27). RESULTS The programme reached 91% in a sample of 151 patients with a mean age of 84 years. There was a high fidelity for the major components of the programme: documentation of geriatric risks (98%), co-management by specialist geriatrics nurse (95%), early rehabilitation (80%), and early discharge planning (74%), except for co-management by the geriatrician (32%). Both patients and healthcare professionals rated G-COACH as acceptable (95 and 94%) and feasible (96 and 74%). The healthcare professionals experienced staffing, competing roles and tasks of the geriatrics nurse and leadership support as important determinants for implementation. CONCLUSIONS The implementation strategy resulted in the successful initiation of the G-COACH programme. G-COACH was perceived as acceptable and feasible. Fidelity was influenced by context factors. Further investigation of the sustainability of the programme is needed. TRIAL REGISTRATION ISRCTN22096382 (21/05/2020).
