Background: The rising incidence of obesity in pediatric populations presents unique challenges in managing postoperative pain, particularly in orthopedic surgeries. Understanding how obesity influences pain perception and opioid requirements is crucial for optimizing pain management strategies.

Methods: A cross-sectional design was employed, enrolling 175 pediatric patients scheduled for elective orthopedic surgery. Patients were classified into obese and non-obese groups based on their body mass index (BMI). Postoperative pain intensity was measured using a validated numerical rating scale, and opioid requirements were documented over the first 48 hours following surgery. Statistical analyses, including correlation and regression models, were utilized to assess associations among the variables.

Results: Obese patients demonstrated significantly higher pain scores and greater opioid consumption compared to non-obese counterparts (p < 0.01). A strong positive correlation was identified between pain intensity and opioid use (r = 0.68, p < 0.01). Multivariate regression analysis revealed that obesity serves as an independent predictor of increased pain intensity and opioid requirement.

Conclusion: The findings emphasize the need for individualized pain management approaches for obese pediatric patients undergoing orthopedic surgery. Clinicians should consider obesity a critical factor in postoperative pain assessment and opioid therapy. Future research should focus on developing multimodal analgesic strategies to improve patient outcomes and reduce the potential for opioid-related complications.
