Measurement and Thermodynamic Modeling of Energy Flux During Intercostal Nerve Cryoablation.

Introduction: Intercostal nerve cryoablation is an increasingly adopted technique to decrease postoperative pain in patients undergoing surgical correction of pectus excavatum (SCOPE). Concerns regarding cryo-induced systemic hypothermia have been raised in pediatric patients; however, assessment of a cooled cryoprobe on body temperature has not been performed. We aimed to determine the energy flux from a maximally cooled cryoprobe and model the possible effects on a whole-body system.

Fluorescence-guided surgery: National trends in adoption and application in pediatric surgery.

Background: Fluorescence-guided surgery (FGS) with indocyanine green (ICG) is a rapidly diffusing surgical innovation, but its utilization in pediatrics remains unknown. We present a cross-sectional descriptive analysis of trends from a national database.

Methods: The Pediatric Health Information System (PHIS) database was queried for patient encounters between January 2016 and July 2021 with an associated ICG administration within 3 days prior to surgery.

Sitting time and long-term weight change in adolescents with severe obesity undergoing surgical and nonoperative weight management.

Background: Prolonged sitting time has been associated with numerous deleterious effects on humans. The degree to which sitting time influences weight loss outcomes of obesity treatments is poorly understood.

Objectives: The objective was to characterize and describe the amount of time spent sitting in an adolescent bariatric surgical and nonoperative cohort and evaluate its relationship with long-term change in body mass index (BMI).
