Postoperative nausea and vomiting after strabismus surgery: mechanisms, treatment, and implications for practice

Area of Science:

• Anesthesiology
• Pediatric Surgery

Background:

• Postoperative nausea and vomiting (PONV) is a significant concern in pediatric anesthesia, particularly following strabismus surgery.
• Understanding the specific challenges of PONV in this patient group is crucial for effective anesthetic management.

Purpose of the Study:

• To provide a comprehensive overview of the etiology, pathophysiology, and mechanisms underlying PONV in children undergoing strabismus surgery.
• To review current pharmacological interventions for managing PONV in this population.
• To discuss implications for future anesthetic practices and research.

Main Methods:

• Literature review of existing studies and clinical guidelines on PONV in pediatric strabismus surgery.
• Analysis of the physiological factors contributing to PONV in this specific surgical context.
• Evaluation of the efficacy and safety profiles of various antiemetic agents.

Main Results:

• Strabismus surgery in children presents a unique risk profile for PONV due to specific anesthetic agents and surgical factors.
• Several pharmacological agents demonstrate efficacy in preventing and treating PONV, with varying side effect profiles.
• Multimodal approaches combining different antiemetic classes may offer superior outcomes.

Conclusions:

• Effective management of PONV in pediatric strabismus surgery requires a thorough understanding of its underlying mechanisms.
• Tailored pharmacological strategies, considering patient-specific risk factors, are essential for optimizing outcomes.
• Further research into novel therapeutic targets and anesthetic techniques is warranted to minimize PONV incidence and improve patient recovery.
