Adverse Events and Resource Utilization After Spinal and General Anesthesia in Infants Undergoing Pyloromyotomy

Area of Science:

• Pediatric Anesthesiology
• Surgical Outcomes Research

Background:

• Growing concern over long-term effects of general anesthesia (GA) in young children.
• Increasing interest in spinal anesthesia (SA) as an alternative for pediatric procedures.

Purpose of the Study:

• To compare the safety and efficacy of SA versus GA in infants undergoing pyloromyotomy.
• To evaluate adverse events, operating room time, and length of stay associated with each anesthesia technique.

Main Methods:

• Retrospective cohort study comparing infants receiving SA (n=218) versus GA (n=206) for pyloromyotomy between 2000-2013.
• Analysis of adverse events within 48 hours, operating room time, and postoperative length of stay.
• Regression analysis to control for demographic and clinical factors.

Main Results:

• Spinal anesthesia infants experienced significantly shorter operating room times (17.5 minutes faster) and shorter postoperative length of stay (1.19 times longer for GA).
• No significant difference in adverse event rates between SA and GA groups (aOR 0.60; 95% CI 0.27-1.36).
• While 96.3% of SA infants had adequate initial analgesia, 35.8% required supplemental anesthetic agents.

Conclusions:

• Spinal anesthesia for infant pylorotomy is associated with reduced operating room time and length of hospital stay compared to general anesthesia.
• SA did not increase adverse event rates and decreased exposure to intravenous and inhaled anesthetics.
• Long-term benefits of SA require further investigation, including assessment of rare adverse events like aspiration.
