General Endotracheal Anesthesia vs Total Intravenous Anesthesia for Children Undergoing Low-Risk Cardiac...

Historically, children undergoing cardiac catheterization have been managed with general endotracheal anesthesia (GETA). However, recent practice has favored general anesthesia with total intravenous anesthesia (TIVA). This study compares procedural outcomes in the pediatric cardiac catheterization laboratory (PCCL) for children undergoing low-risk cardiac catheterization with GETA vs. TIVA. We reviewed all patients aged 1-12 years, who underwent outpatient diagnostic or simple interventional catheterization from January 2016 to September 2023. Patients were divided into cohorts by type of anesthesia (GETA vs. TIVA). The primary outcome measure was total patient time in the PCCL ("door-to-door" time). Secondary outcomes were procedure duration ("sheath time"), length of hospital stay, and the major adverse event (MAE) rate. A total of 401 patients were included. Of these patients, 226 underwent GETA and 175 underwent TIVA. There were 148 interventional procedures and 72 patients had single-ventricle physiology. There was no significant difference between the two cohorts in terms of demographic factors such as age, weight, procedure indication, and physiological complexity as well as outcomes such as sheath time, hospital stay, and MAE. However, the average door-to-door time of the TIVA cohort was 25 min shorter than the GETA cohort (p < 0.001). In this single center, retrospective study of anesthesia management for children undergoing low-risk cardiac catheterization, TIVA is associated with significantly shorter door-to-door time in the PCCL without an increase in procedure duration, hospital stay, or rate of complications. These findings have potential clinical significance supporting increased use of TIVA during pediatric cardiac catheterization.
