BACKGROUND
Vasoplegia after cardiac surgery is associated with adverse outcomes. However, the clinical effects of vasoplegia and the significance of its duration after continuous-flow left ventricular assist device (CF-LVAD) implantation are less known.
OBJECTIVES
This study aimed to identify predictors of and outcomes from transient vs prolonged vasoplegia after CF-LVAD implantation.
METHODS
The study was a retrospective review of consecutive patients who underwent CF-LVAD implantation between January 1, 2005, and December 31, 2017. Vasoplegia was defined as the presence of all of the following: mean arterial pressure ≤65 mm Hg, vasopressor (epinephrine, norepinephrine, vasopressin, or dopamine) use for >6 hours within the first 24 hours postoperatively, cardiac index ≥2.2 L/min/m and systemic vascular resistance <800 dyne/s/cm, and vasodilatory shock not attributable to other causes. Prolonged vasoplegia was defined as that lasting 12 to 24 hours; transient vasoplegia was that lasting 6 to <12 hours. Patient characteristics, outcomes, and risk factors were analyzed.
RESULTS
Of the 600 patients who underwent CF-LVAD implantation during the study period, 182 (30.3%) developed vasoplegia. Mean patient age was similar between the vasoplegia and no-vasoplegia groups. Prolonged vasoplegia (n = 78; 13.0%), compared with transient vasoplegia (n = 104; 17.3%), was associated with greater 30-day mortality (16.7% vs 5.8%; = 0.02). Risk factors for prolonged vasoplegia included preoperative dialysis and elevated body mass index.
CONCLUSIONS
Compared with vasoplegia overall, prolonged vasoplegia was associated with worse survival after CF-LVAD implantation. Treatment to avoid or minimize progression to prolonged vasoplegia may be warranted.

Review
In recent years, with the widespread use of chest CT, the detection rate of pulmonary nodules has significantly increased (Abtin and Brown, J Clin Oncol 31:1002-8, 2013). Video-assisted thoracoscopic surgery (VATS) is the most commonly used method for suspected malignant nodules. However, for nodules with a diameter less than 1 cm, or located more than 1.5 cm from the pleural edge, especially ground-glass nodules, it is challenging to achieve precise intraoperative localization by manual palpation (Ciriaco et al., Eur J Cardiothorac Surg 25:429-33, 2004). Therefore, preoperative accurate localization of such nodules becomes a necessary condition for precise resection. This article provides a comprehensive review and analysis of the research progress in pulmonary nodule localization, focusing on four major localization techniques: Percutaneous puncture-assisted localization, Bronchoscopic preoperative pulmonary nodule localization, 3D Printing-Assisted Localization, and intraoperative ultrasound-guided pulmonary nodule localization.

BACKGROUND
Antiphospholipid syndrome (APS) is a systemic autoimmune condition that predisposes patients to venous thromboembolism (VTE). Although many studies have explored risk factors for VTE after joint reconstructive procedures, the impact of APS is still unclear.
MATERIALS AND METHODS
A retrospective cohort study was conducted using TriNetX, a health care database that includes 442,494 patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA). Ninety-day postoperative complications and 1- and 2-year surgical complications were compared between patients with and without preexisting APS. Patients underwent propensity score matching in a 1:1 ratio based on relevant comorbidities.
RESULTS
Patients undergoing THA or TKA with APS, compared with those without, had higher rates of deep venous thrombosis (hip: 9.2% vs 6.0%, odds ratio, 1.589, =.022; knee: 10.5% vs 4.1%, odds ratio, 2.763, <.001), pulmonary embolism (hip: 6.9% vs 3.6%, odds ratio, 1.992, =.005; knee: 8.4% vs 3.0%, odds ratio, 2.989, <.001), and anemia (hip: 24.8% vs 18.6%, odds ratio, 1.447, =.004; knee: 18.5% vs 13.9%, odds ratio, 1.406, =.007). Patients undergoing THA with APS also had higher rates of urinary tract infection (5.0% vs 2.8%, odds ratio, 1.842, =.029) and pneumonia (3.7% vs 1.8%, odds ratio, 2.119, =.025). APS did not impact rates of surgical complications or revision surgery.
CONCLUSION
Overall, APS heightens patients' risk for complications after THA and TKA. Specific anticoagulation protocols and preoperative risk stratification should be implemented to reduce the risk of adverse events. [. 202;4x(x):xx-xx.].

Although the role of sleep in modulating epileptic activity is well established, many epileptologists overlook the significance of considering sleep during presurgical epilepsy evaluations in cases of drug-resistant epilepsy. Here, we conducted a comprehensive literature review from January 2000 to May 2023 using the PubMed electronic database and compiled evidence to highlight the need to revise the current clinical approach. All articles were assessed for eligibility by two independent reviewers. Our aim was to shed light on the clinical value of incorporating sleep monitoring into presurgical evaluations with stereo-electroencephalography. We present the latest developments on the important bidirectional interactions between sleep and various forms of epileptic activity observed in stereo-electroencephalography recordings. Specifically, epileptic activity is modulated by different sleep stages, peaking in non-rapid eye movement sleep, while being suppressed in rapid eye movement sleep. However, this modulation can vary across different brain regions, underlining the need to account for sleep to accurately pinpoint the epileptogenic zone during presurgical assessments. Finally, we offer practical solutions, such as automated sleep scoring algorithms using stereo-electroencephalography data alone, to seamlessly integrate sleep monitoring into routine clinical practice. It is hoped that this review will provide clinicians with a readily accessible roadmap to the latest evidence concerning the clinical utility of sleep monitoring in the context of stereo-electroencephalography and aid the development of therapeutic and diagnostic strategies to improve patient surgical outcomes.

BACKGROUND
High energy requirements and poor feeding can lead to growth failure in patients with ventricular septal defect (VSD), but effects of preoperative malnutrition on surgical outcomes are poorly understood, especially in low-resource settings.
METHODS AND RESULTS
We analyzed a cohort of children <5 years of age undergoing VSD closure at 60 global centers participating in the International Quality Improvement Collaborative for Congenital Heart Disease, 2015 to 2020. We calculated adjusted odds ratios (ORs) for in-hospital death and major infection and adjusted coefficients for duration of intensive care unit stay for 4 measures of malnutrition: severe wasting (weight-for-height score, <-3), moderate wasting (-3
care unit stay. Underweight was the strongest predictor of adverse outcomes. Children meeting criteria for all 3 (stunting, wasting, and underweight) had 17.2 times higher odds of mortality (<0.001) than nonmalnourished children. CONCLUSIONS
Malnutrition was associated with mortality, infection, and longer intensive care unit stay in a global cohort of children undergoing VSD closure.

The Laryngoscope Jun 2024Evaluate implementation of an institutional protocol to reduce the time to removal of esophageal button battery (BB) and increase use of mitigation strategies.
OBJECTIVE
Evaluate implementation of an institutional protocol to reduce the time to removal of esophageal button battery (BB) and increase use of mitigation strategies.
METHODS
We developed a protocol for esophageal BB management [Zakai's Protocol (ZP)]. All cases of esophageal BB impaction managed at a tertiary care center before and after implementation from 2011 to 2023 were reviewed. Time to BB removal, adherence to critical steps, and use of mitigation strategies (honey/sucralfate, acetic acid) were evaluated.
RESULTS
Fifty-one patients (38 pre-ZP, 13 post-ZP) were included. Median age was 2.3 years (IQR 1.3-3.4). After implementation, the time from arrival at the institution to arrival in the operating room (OR) reduced by 4.2 h [4.6 h (IQR 3.9-6.5) to 0.4 h (IQR 0.3-0.6), p < 0.001] and there was improvement in all management steps. The number of referrals direct to otolaryngology increased from 51% to 92%, arrival notification increased from 86% to 100%, avoidance of second x-ray increased from 63% to 100%, and direct transfer to OR increased from 92% to 100%. Adherence to mitigation strategies such as preoperative administration of honey or sucralfate increased from 0% to 38%, intraoperative use of acetic acid from 3% to 77%, and nasogastric tube insertion from 53% to 92%.
CONCLUSION
Implementation of ZP substantially reduced the time to BB removal and the use of mitigation strategies in our tertiary care institution. Additional strategies focused on prevention of BB ingestion, and shortening the transfer time to the tertiary care hospital are required to prevent erosive complications.

Review
PURPOSE OF REVIEW
The integration of artificial intelligence (AI) in nonoperating room anesthesia (NORA) represents a timely and significant advancement. As the demand for NORA services expands, the application of AI is poised to improve patient selection, perioperative care, and anesthesia delivery. This review examines AI's growing impact on NORA and how it can optimize our clinical practice in the near future.
RECENT FINDINGS
AI has already improved various aspects of anesthesia, including preoperative assessment, intraoperative management, and postoperative care. Studies highlight AI's role in patient risk stratification, real-time decision support, and predictive modeling for patient outcomes. Notably, AI applications can be used to target patients at risk of complications, alert clinicians to the upcoming occurrence of an intraoperative adverse event such as hypotension or hypoxemia, or predict their tolerance of anesthesia after the procedure. Despite these advances, challenges persist, including ethical considerations, algorithmic bias, data security, and the need for transparent decision-making processes within AI systems.
SUMMARY
The findings underscore the substantial benefits of AI in NORA, which include improved safety, efficiency, and personalized care. AI's predictive capabilities in assessing hypoxemia risk and other perioperative events, have demonstrated potential to exceed human prognostic accuracy. The implications of these findings advocate for a careful yet progressive adoption of AI in clinical practice, encouraging the development of robust ethical guidelines, continual professional training, and comprehensive data management strategies. Furthermore, AI's role in anesthesia underscores the need for multidisciplinary research to address the limitations and fully leverage AI's capabilities for patient-centered anesthesia care.

Turk Gogus Kalp Damar Cerrahisi Dergisi Apr 2024This second harvest of the Congenital Heart Surgery Database intended to compare current results with international databases.
BACKGROUND
This second harvest of the Congenital Heart Surgery Database intended to compare current results with international databases.
METHODS
This retrospective study examined a total of 4007 congenital heart surgery procedures from 15 centers in the Congenital Heart Surgery Database between January 2018 and January 2023. International diagnostic and procedural codes were used for data entry. STAT (Society of Thoracic Surgeons and European Association for Cardiothoracic Surgery) mortality scores and categories were used for comparison of the data. Surgical priority status was modified from American Society of Anesthesiologist guidelines. Centers that sent more than 5 cases to the database were included to the study.
RESULTS
Cardiopulmonary bypass and cardioplegic arrest were performed in 2,983 (74.4%) procedures. General risk factors were present in 22.6% of the patients, such as genetic anomaly, syndrome, or prematurity. Overall, 18.9% of the patients had preoperative risk factors (e.g., mechanical ventilation, renal failure, and sepsis). Of the procedures, 610 (15.2%) were performed on neonates, 1,450 (36.2%) on infants, 1,803 (45%) on children, and 144 (3.6%) on adults. The operative timing was elective in 56.5% of the patients, 34.4% were urgent, 8% were emergent, and 1.1% were rescue procedures. Extracorporeal membrane oxygenation support was used in 163 (4%) patients, with a 34.3% survival rate. Overall mortality in this series was 6.7% (n=271). Risk for mortality was higher in patients with general risk factors, such as prematurity, low birth weight neonates, and heterotaxy syndrome. Mortality for patients with preoperative mechanical ventilation was 17.5%. Pulmonary hypertension and preoperative circulatory shock had 11.6% and 10% mortality rates, respectively. Mortality for patients who had no preoperative risk factor was 3.9%. Neonates had the highest mortality rate (20.5%). Intensive care unit and hospital stay time for neonates (median of 17.8 days and 24.8 days, respectively) were also higher than the other age groups. Infants had 6.2% mortality. Hospital mortality was 2.8% for children and 3.5% for adults. Mortality rate was 2.8% for elective cases. Observed mortality rates were higher than expected in the fourth and fifth categories of the STAT system (observed, 14.8% and 51.9%; expected, 9.9% and 23.1%; respectively).
CONCLUSION
For the first time, outcomes of congenital heart surgery in Türkiye could be compared to the current world experience with this multicenter database study. Increased mortality rate of neonatal and complex heart operations could be delineated as areas that need improvement. The Congenital Heart Surgery Database has great potential for quality improvement of congenital heart surgery in Türkiye. In the long term, participation of more centers in the database may allow more accurate risk adjustment.

BACKGROUND
Open-heart surgery is challenging in preterm neonates and infants, and its feasibility in low-resource settings has not been defined. We describe our institutional experience with open-heart surgeries performed on consecutive preterm infants.
MATERIALS METHODS AND RESULTS
This was a single-center retrospective cohort from a tertiary hospital in Southern India and included consecutive preterm neonates (<37 weeks) admitted for open-heart surgery. This report is limited to babies who were <3 months at the surgery. The salient features of the 15 preterm included twin gestation: 7 (46.7%); median gestational age at birth: 35 weeks (28-36 weeks); median corrected gestational age at surgery: 37 weeks (33-40 weeks); birth weight: 1.75 kg (1.0-2.6 kg); weight at surgery: 1.8 kg (1.2-2.9 kg); and small for gestational age: 12 (80%). The heart defects included transposition of the great arteries (7), total anomalous pulmonary venous return (3), large ventricular septal defect (VSD) (1), and VSD with coarctation of the aorta (4). Eleven (73%) were mechanically ventilated preoperatively and five had preoperative sepsis. The mean cardiopulmonary bypass time was 169.7 ± 61.5 min, and cross-clamp time was 99.7 ± 43.8 min. There was no inhospital mortality; one baby expired during follow-up at 1 month. Postoperative mechanical ventilation duration was 126.50 h (84.25-231.50 h), and intensive care unit stay was 13.5 days (9-20.8). The total hospital stay was 39 days (11-95 days). Two children (13.3%) had postoperative sepsis.
CONCLUSION
Through collaborative multidisciplinary management, excellent outcomes are feasible in low-resource environments for selected preterm neonates undergoing corrective open-heart operations.

PURPOSE
This study investigates the effect of the body mass index (BMI) on the early (2 years) to midterm (5 years) results of medial opening wedge high tibial osteotomy (MOWHTO).
METHODS
A prospectively maintained single-centre database of 1138 knee osteotomies, between 2002 and 2022, was retrospectively reviewed. Adult patients who underwent MOWHTO for symptomatic unicompartmental medial knee osteoarthritis (OA), with varus knee malalignment, having failed conservative management, were included. Patients were categorized into three groups according to their BMI as per the classification from the National Institute for Health and Care Excellence (NICE): the healthy weight (HW) group (BMI of 18.5-24.9 kg/m), the overweight (OW) (BMI of 25-29.9 kg/m), and the obesity (OB) group (BMI ≥ 30 kg/m). Multiple patient-reported outcome measures (n = 6) were recorded preoperatively and at 2 and 5 years postoperatively. Deformity analysis was undertaken preoperatively and postoperatively. The relative risk (RR) of the complications between the HW, OW and OB groups was calculated. The rate of conversion to arthroplasty, and 5 and 10 years survivorship were recorded, as well as the hazard ratio (HR) of BMI on survivorship.
RESULTS
A total of 574 cases were included in the study: the HW group (n = 96), the OW group (n = 233) and the OB group (n = 245), with a mean BMI of 23 ± 1.5 kg/m, 27.4 ± 1.4 kg/m and 34.4 ± 3.8 kg/m, respectively. The mean follow-up was 13.3 years (4.8-20.3). The mean mechanical tibiofemoral angle corrections were in the HW group: 7.1 ± 3°, OW group: 6.6 ± 3.5° and OB group: 7.1 ± 3.8°, with no intergroup significant difference (p = n.s.). Clinically, despite lower preoperative scores in the OW and OB groups, no difference was observed postoperatively amongst the three groups. The overall complication rate was 12.5% in the HW group, 6.8% in the OW group, and 9.8% in the OB group. There was no significant difference in the RR of complications between the HW and OW groups (RR = 0.6, 95% confidence interval [CI] = 0.3-1.3) (p = 0.2), and the HW and OB groups (RR = 0.8; 95% CI = 0.3-2.2) (p = 0.7). There was no overall significant difference in survival outcomes based on the BMI between the three groups (p = 0.4). The HR of conversion to arthroplasty between the HW and OW groups was 1.4 [95% CI = 0.6-3.5](p = 0.5) and between the HW and OB groups was 1.8 [95% CI = 0.8-4.4] (p = 0.2).
CONCLUSION
BMI has no significant effect on either the radiological corrections, clinical outcomes, complications or survivorship of MOWHTO at short- to medium-term follow-up. No specific cutoff point for BMI can be recommended as a contraindication to MOWHTO.
