The Year in Cardiothoracic Transplant Anesthesia: Selected Highlights From 2021 Part II: Cardiac Transplantation.

This article spotlights the research highlights of this year that specifically pertain to the specialty of anesthesia for heart transplantation. This includes the research on recent developments in the selection and optimization of donors and recipients, including the use of donation after cardiorespiratory death and extended criteria donors, the use of mechanical circulatory support and nonmechanical circulatory support as bridges to transplantation, the effect of COVID-19 on heart transplantation candidates and recipients, and new advances in the perioperative management of these patients, including the use of echocardiography and postoperative outcomes, focusing on renal and cerebral outcomes.

The Year in Perioperative Echocardiography: Selected Highlights From 2022.

THIS SPECIAL article is part of an annual series for the Journal of Cardiothoracic and Vascular Anesthesia. The authors thank the editor-in-chief, Dr. Kaplan, and the Editorial Board for the opportunity to continue this series, which focuses on the past year's research highlights that pertain to perioperative echocardiography in relation to cardiothoracic and vascular anesthesia. The major selected themes for 2022 include (1) updates on mitral valve assessments and interventions, (2) training and simulation updates, (3) outcomes and complications of transesophageal echocardiography, and (4) point-of-care cardiac ultrasound. The themes selected for this special article are just a sample of the advances in perioperative echocardiography during 2022. An appreciation and understanding of these highlights will help to ensure and improve the perioperative outcomes for patients with cardiovascular disease undergoing cardiac surgery.

A Randomized Pilot Study Assessing if SEDLine Monitoring During Induction of Surgical Patients is Associated With Reduced Dosage of Administered Induction Agents.

Background. Intubations, especially in emergent settings, carry a high risk of hemodynamic instability with potentially catastrophic outcomes. Weight-based dosing of induction drugs can be inappropriately high for elective or emergent intubations and lead to hemodynamic instability. We hypothesized that monitoring the patient state index of SEDLine monitors (Masimo, Irvine, CA) would decrease the dose of induction drugs in the operating room during elective intubations.Methods. In this randomized study, SEDLine monitoring was provided to the intervention group but not to the control group during the induction of anesthesia in the operating room. Anesthesia providers in the intervention group were advised to titrate induction drugs to a Patient State Index of <50 before proceeding with intubation. The primary outcome was the induction dose of propofol and etomidate per kilogram normalized to propofol dose equivalents. Secondary outcomes included supplemental doses of ketamine, midazolam, fentanyl, phenylephrine, and ephedrine per kg, time from induction to intubation, administration of additional propofol or vasopressors after induction, mean arterial pressure ≥ or <65 mmHg, and lowest mean arterial pressure post-induction.Results. We found no significant difference in propofol equivalents between groups (P = .41). Using a SEDLine decreased the odds that a patient would require vasopressors during induction (odds ratio of .39 [95% confidence interval, .15-.98]).Conclusion. SEDLine monitoring during induction did not decrease dosing of the induction drugs etomidate and propofol but decreased the odds of receiving vasopressors. Further studies are warranted to assess the utility of processed electroencephalography in emergent intubations outside of the operating room.

Surgical Site Infection in Thoracic Surgery Is Not Associated With Perioperative Hypothermia.

INTRODUCTION: The Surgical Care Improvement Project (SCIP) added the SCIP-Inf-10 measure to mandate that all surgical patients have perioperative temperature management to reduce surgical site infection. While the basis of this measure originated in colorectal surgery, we hypothesized that this would also apply to thoracic surgery patients. METHODS: This was a retrospective single-center pilot study reviewing two years of thoracic surgery cases for the incidence and duration of hypothermia during the operation and surgical site infection occurring within 30 days. Hypothermia was defined as a core temperature of < 36° C.  Results: A total of 317 patients were included in the study. Sixty-two percent of patients were identified as hypothermic. The average intraoperative temperature was 35.4°C ± 0.8°C in the hypothermic group and 36.4°C ± 0.3°C in the normothermic group. There were four surgical site infections in the study with three cases from the <36°C group (p = 1). There was no difference in average post-anesthesia care unit length of stay between the groups. The average hospital length of stay was 5.5 ± 5.2 days for the hypothermic group and 8.6 ± 12.8 days for the normothermic group (p=0.0024). CONCLUSION: Perioperative hypothermia was common in thoracic surgery and did not have a negative impact on surgical site infection.

Recommendations for developing clinical care protocols during pandemics: From theory and practice.

In 2019, a novel coronavirus called the severe acute respiratory syndrome coronavirus 2 led to the outbreak of the coronavirus disease 2019, which was deemed a pandemic by the World Health Organization in March 2020. Owing to the accelerated rate of mortality and utilization of hospital resources, health care systems had to adapt to these major changes. This affected patient care across all disciplines and specifically within the perioperative services. In this review, we discuss the strategies and pitfalls of how perioperative services in a large academic medical center responded to the initial onset of a pandemic, adjustments made to airway management and anesthesia specialty services - including critical care medicine, obstetric anesthesiology, and cardiac anesthesiology - and strategies for reopening surgical caseload during the pandemic.

Clinical significance of incidentally detected lead perforations by computed tomography.

BACKGROUND: Computed tomography (CT) has an established role in detecting perforation of implanted pacemaker and defibrillator leads. The clinical significance of incidental finding of delayed lead perforation remains unclear. The aim of this study was to assess the prevalence of lead perforation as detected by CT in a cohort of patients undergoing transvenous laser lead extraction and characterize the association between finding of incidental lead perforation with periprocedural outcomes. METHODS: Consecutive patients that underwent chest CT and lead extraction were retrospectively assessed for presence of lead perforation. A total of 143 patients and 348 leads were assessed. The finding of lead perforation was correlated with findings from peri-procedural transesophageal echocardiography (TEE) and outcomes of the lead extraction procedure. RESULTS: Lead perforations (including perforations <5 mm and ≥5 mm) were detected in 66 (46%) patients and 73 (21%) leads. Lead perforation ≥5 mm were less common and detected in 13 (9%) of patients and 14 (4%) of leads. There was no significant difference in the rates of peri-procedural death, cardiac avulsion, cardiac tamponade or post-extraction pericardial effusion in patients with and without lead perforation. CONCLUSIONS: Incidental delayed lead perforations detected by CT are common and do not correlate with significant TEE findings or adverse peri-procedural outcomes in patients undergoing lead extraction. Larger studies are needed to further characterize the frequency and safety of these findings.
