Is routine pre-operative cardiac evaluation necessary in obese children undergoing adenotonsillectomy for OSA?

Area of Science:

• Pediatric Surgery
• Cardiology
• Anesthesiology

Background:

• Adenotonsillectomy (T&A) is a common procedure for pediatric obstructive sleep apnea (OSA).
• Obese children face higher risks for OSA and potential anesthetic-related cardiovascular complications.
• No standardized cardiac evaluation protocol exists for obese children before T&A.

Purpose of the Study:

• To determine if preoperative cardiac evaluations predict postoperative complications in obese children undergoing T&A for OSA.

Main Methods:

• Retrospective cohort review of 241 obese children (BMI ≥ 25 kg/m²).
• Patients categorized into three groups based on preoperative cardiac evaluation status: none, evaluation with no significant findings, or evaluation with significant findings.
• Comparison of postoperative cardiac-related complications across the groups.

Main Results:

• Group 3 (preoperative cardiac findings) showed more complications, primarily longer hospital stays (>24 hours), without clear cardiac sequelae.
• No cases of pulmonary edema, postoperative re-intubation, or death were observed.
• Preoperative cardiac workup did not prove beneficial in predicting adverse outcomes.

Conclusions:

• Routine preoperative cardiac workup is not beneficial for predicting postoperative complications in obese children undergoing T&A for OSA at a tertiary care center.
• The study suggests that current cardiac evaluation protocols may not be effective in identifying children at significant risk for T&A-related complications.
