Safety and efficacy of high thoracic epidural analgesia for chest wall surgery in young adolescents: A retrospective cohort analysis and a new standardised definition for success rate.

BACKGROUND: Chest wall surgery for the correction of pectus excavatum or pectus carinatum has gained increased interest in recent years. Adequate pain treatment, respiratory physiotherapy and early ambulation are key to improving the outcomes. Although thoracic epidural analgesia is highly effective, its safety is controversial, leading to extensive scrutiny and questioning of its role. OBJECTIVES: We hypothesise that thoracic epidural analgesia is effective and well tolerated to use in adolescents, with a high success rate and low pain scores. DESIGN: Observational retrospective cohort study. SETTING: All adolescent cases in a high-volume academic tertiary chest wall surgery centre between March 1993 and December 2017 were included. PATIENTS: A total of 1117 patients aged from 12 to 19 years of age and receiving either Ravvitch, Nuss or Abramson chest wall reconstruction for pectus excavatum were identified in our institutional chest wall surgery database. After applying selection and exclusion criteria, 532 patients were included in the current analysis. MAIN OUTCOME MEASURES: The primary endpoint of this study was the safety of epidural analgesia, assessed by the incidence of acute adverse events. Secondary endpoints were block success rates using a specific novel definition, and analgesic efficacy using recorded postoperative pain scores. RESULTS: More than 60% of patients experienced one or more adverse events. However, all events were minor and without consequences. No serious or long-term adverse events were detected. The success rate of thoracic epidural placement was 81%. Low postoperative pain scores were observed. CONCLUSION: Thoracic epidural analgesia is an extremely effective pain control technique, with a surprisingly high number of minor adverse events but safe with regard to serious adverse events. TRIAL REGISTRATION: The local research ethics committee approved and registered this study on 16 May 2022 (registration number: S66594).

Percutaneous pulmonary aspiration thrombectomy in an adolescent fontan patient using a large-bore system.

We describe the safe and effective percutaneous pulmonary thrombectomy in an 18-year-old female with a Fontan circulation using the FlowTriever® device (Inari Medical®, Irvine, US). Aspiration thrombectomy of both pulmonary arteries was performed using 24 and 16 F FlowTriever® catheters retrieving large amounts of thrombus material resulting in near total angiographic recanalization.

Anesthesia for Combined Heart-Liver Transplantation: A Narrative Review.

In 1984, 21 years after the first liver transplantation, Thomas Starzl achieved a milestone by performing the world's first combined heart-liver transplantation. While still uncommon, the practice of combined heart-liver transplants is on the rise globally. In this review, the authors delve into the current literature on this procedure, highlighting the evolving landscape and key considerations for anesthesiologists. Over the years, there has been a remarkable increase in the number of combined heart-liver transplantations conducted worldwide. This surge is largely attributed to the growing population of adult survivors with single-ventricle physiology, palliated with a Fontan procedure, who later present with late Fontan failure and Fontan-associated liver disease. Research indicates that combined heart-liver transplantation is an effective treatment option, with reported outcomes comparable with isolated heart or liver transplants. Managing anesthesia during a combined heart-liver transplant procedure is challenging, especially in the context of underlying Fontan physiology. International experience in this field remains somewhat limited, with most techniques derived from expert opinions or experiences with single-organ heart and liver transplants. These procedures are highly complex and performed infrequently. As the number of combined heart-liver transplants continues to rise globally, there is a growing need for clear guidance on periprocedural surgical and anesthetic management. Anesthesiologists overseeing these patients must consider multiple factors, balancing various comorbidities with significant hemodynamic and metabolic shifts. An increase in (multicenter) studies focusing on specific interventions to enhance patient and organ outcomes is anticipated in the coming years.

Epidural analgesia in labour: separating fact from fiction for autism and neurodevelopment.

Having epidural analgesia in labour has been associated with a later diagnosis of autism spectrum disorder in the offspring, resulting in concerns about childhood wellbeing. Neurodevelopmental changes are inconsistently reported in the literature, creating challenges in the interpretation of these findings. Here we explore the limitations of the current evidence base, and why findings differ between studies, concluding that the current body of evidence does not support a causal association between use of epidural analgesia in labour and autism spectrum disorder.

Efficiency of CONTRAfluran™ in reducing sevoflurane pollution from maintenance anaesthesia in minimal flow end-tidal control mode for laparoscopic surgery: Efficiency of CONTRAfluran™.

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.

The patient with congenital heart disease in ambulatory surgery.

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.

International Survey on Perioperative Management of Patients With Infective Endocarditis.

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.
