Background and Objective: Inguinal hernia is a common surgical condition, and surgery is considered the most effective treatment. This study compares the outcomes of inguinal hernia surgery performed under local and spinal anesthesia at Rattanaburi Hospital.
Methods: This study is a retrospective cohort study involving patients diagnosed with inguinal hernia who underwent treatment at Rattanaburi Hospital. The sample size is 33 patients per group. Data were analyzed using descriptive and inferential statistics, including the chi-square test, T-test, and repeated ANOVA.
Results: In the elective open repair primary unilateral inguinal hernia surgery study, 66 cases were analyzed, with 33 patients performed under local anesthesia and 33 patients under spinal anesthesia. In the group that received local anesthesia, one case (3.03%) experienced a complication of bradycardia during surgery. However, no complications were reported in the spinal anesthesia group during surgery. Regarding post-surgery complications within the first week, the local anesthesia group reported one case of seroma (3.03%). In contrast, the spinal anesthesia group had three cases of wound hematoma (9.09%), one case of seroma (3.03%), and three cases of urinary retention (9.09%). When comparing the surgical results using pain scores measured on the Visual Analog Scale (VAS), the average VAS pain scores at 6 hours, 24 hours, and 48 hours significantly differ between the two groups. During the one-month follow-up, both groups showed no need for treatment of recurrent cases. The average treatment cost for the local anesthesia group was 13,182.42 baht, while the spinal anesthesia group had an average price of 20,872.18 baht. The average cost difference between the two groups was 7,689.75 baht (p-value < 0.01). Patient satisfaction did not significantly differ between the two groups.
Conclusion: Inguinal hernia surgery performed with local anesthesia is a safe procedure with few complications and lower costs. A hospital stay is unnecessary, and postoperative pain levels are lower than those observed in the spinal anesthesia group, especially after 6 hours.
