Multicentre analysis of severe perioperative adverse events in children undergoing surgery who were infected with SARS-CoV-2: a propensity score-adjusted analysis.

Background: The incidence of severe adverse events in children with SARS-CoV-2 undergoing anaesthesia has not been well established. We examined the relationship between SARS-CoV-2 infection and severe perioperative adverse events in children.

Methods: This multicentre (21 North American institutions), retrospective cohort study included children <18 years old, with American Society of Anesthesiologists physical status (ASA PS) of 1-4 and non-severe SARS-CoV-2, who underwent general anaesthesia between April 1, 2020, and March 31, 2021.

Pediatric obstructive sleep apnea: a prospective observational study of respiratory events in the immediate recovery period after adenotonsillectomy.

Background: Adenotonsillectomy is often curative for pediatric obstructive sleep apnea, yet children remain at high risk of respiratory complications in the postoperative period. We sought to determine the incidence and risk factors for respiratory depression and airway obstruction, as well as clinically apparent respiratory events in the post-anesthesia care unit (PACU) in high-risk children after adenotonsillectomy.

Methods: In this prospective cohort study, we enrolled 60 high-risk children having adenotonsillectomy.

Association between preoperative respiratory symptoms and perioperative respiratory adverse events in pediatric patients with positive viral testing.

Study Objective: To determine the association between the presence of upper respiratory tract viral infection symptoms and occurrence of perioperative respiratory adverse events (PRAE) in children with positive viral screening, and to analyze the risk of PRAE in children with SARS-CoV-2 compared to non-SARS-CoV-2 infection.

Design: A prospective cohort study.

Setting: A tertiary, freestanding pediatric hospital in Dallas, Texas.

Angelman and Prader-Willi Syndromes: Sister Imprinting Disorders With High Complication Rates Following Spinal Deformity Surgery.

We sought to examine the modern surgical treatment of spinal deformity associated with sister imprinting disorders, Prader-Willi syndrome (PWS) and Angelman syndrome (AS), with emphasis on the specific complications encountered in these patient populations. Fifteen patients with PWS and 5 patients with AS who underwent surgical intervention for spinal deformity between 2000 and 2018 were identified. Postoperative complications were classified using the modified Clavien-Dindo-Sink (CDS) system and further categorized into specific subtypes including excessive drainage, dehiscence, implant failure, infection, and delayed wound healing.

Two AIS spine surgeries on the same day by the same surgeon: is performance and outcome the same for the second patient?

Study Design: Retrospective case-controlled study.

Objectives: To analyze the overall performance and outcome of two-a-day surgery days for adolescent idiopathic scoliosis (AIS). As a method to improve efficiency and operating room utilization, some surgeons are now performing two surgeries for AIS in a single day.

Intraoperative Prone Radiographs During Scheuermann Kyphosis Correction Closely Estimate Standing Thoracic and Lumbar Parameters at 2 Years.

Background: In patients with Scheuermann kyphosis (SK) undergoing posterior spinal fusion with instrumentation (PSFI), intraoperative lateral radiographs assess deformity correction in the prone position. The relationship between thoracic and (partially un-instrumented) lumbar parameters on prone intraoperative versus standing postoperative radiographs is unknown.

Methods: Forty-five consecutive patients with SK who underwent PSFI between 2007 and 2014 were reviewed.

The incidence and risk factors for perioperative allogeneic blood transfusion in primary idiopathic scoliosis surgery.

Study Design: Case-control study.

Objectives: Evaluate the rate and risk factors for perioperative allogeneic blood transfusion (ABT) in primary idiopathic scoliosis surgery at a single institution. Avoiding perioperative ABT is ideal as transfusions are associated with adverse reactions, increased rates of infection, prolonged hospitalization, additional laboratory testing, and increased cost.
