Abstract Introduction: The choice between regional and general anesthesia for inguinal hernia repair is of significant clinical importance, as it directly impacts postoperative pain, complication rates, recovery trajectories, and long-term patient outcomes. With increasing emphasis on individualized care and enhanced recovery protocols, determining the most effective anesthetic approach is essential to optimizing surgical results, minimizing adverse effects, and improving patient satisfaction, particularly in high-volume procedures with substantial global health implications.
Material and methods: This systematic review assessed the impact of regional versus general anesthesia on postoperative pain and complications following inguinal hernia repair. Using predefined criteria, relevant studies were identified through comprehensive database searches. Data were extracted on pain scores, complications, and recovery outcomes. Risk of bias was evaluated with validated tools, and meta-analyses with subgroup analyses addressed heterogeneity.
Results: This systematic review analyzed five studies comparing regional and general anesthesia in inguinal hernia repair. Regional anesthesia, particularly spinal, was associated with significantly lower postoperative pain scores and shorter hospital stays. While general anesthesia showed higher rates of nausea and vomiting, regional techniques were linked to a greater incidence of urinary retention.
Conclusion: Regional anesthesia for inguinal hernia repair provides superior postoperative pain control and reduces nausea and vomiting compared to general anesthesia. Although urinary retention is more frequent with regional techniques, overall complication rates remain low.
