Intra- and Peri-Operative Cardiac Arrest in Pediatric Patients: Epidemiology, Risk Factors, Mechanisms, and...

Area of Science:

• Pediatric Anesthesiology
• Critical Care Medicine
• Cardiovascular Surgery

Background:

• Intraoperative (IOCA) and perioperative cardiac arrest (POCA) in pediatric patients is a rare but severe complication.
• Despite advancements, the incidence of IOCA/POCA in children has remained stable over 20 years, with rates of 3-22 per 10,000 noncardiac surgery cases.

Purpose of the Study:

• To review the epidemiology, risk factors, and mechanisms of pediatric IOCA and POCA.
• To provide clinicians with evidence-based management strategies for these critical events.

Main Methods:

• Systematic review of current evidence on pediatric IOCA and POCA.
• Synthesis of data on incidence, risk factors, and outcomes.

Main Results:

• Key risk factors include young age (neonates/infants), high ASA status, emergency surgery, congenital heart disease (CHD), and pulmonary hypertension.
• Respiratory events are the primary cause of anesthesia-related arrest; cardiovascular causes have higher mortality.
• Prevention strategies include preoperative risk stratification and team communication.

Conclusions:

• Effective management necessitates rapid recognition, high-quality cardiopulmonary resuscitation, and consideration of extracorporeal cardiopulmonary resuscitation (ECPR) for refractory cases.
• Continued focus on prevention and preparedness is crucial for improving outcomes in pediatric cardiac arrest during surgery.
