ABSTRACT
Objective: To compare the efficiency of two anesthetic procedures in patients to be subjected to tension-free hernia repair.
Setting: General Regional Hospital 196 (IMSS, Mexican Social Security Institute).
Design: Prospective, quasi-experimental.
Statistical analysis: Student’s t and chi square tests.
Patients and method: Eighty-nine patients were analyzed. The study was performed from July to September 2006. Patients were randomly assigned to two groups. One group had 47 patients operated with regional anesthesia and the other had 42 patients operated under local anesthesia.
Results: Pain was assessed by means of the visual analog scale (VAS); patients with local anesthesia graded pain caused by the puncture with 6; the group with local anesthesia graded it with 3. Complications with regional anesthesia were: four dura-mater punctures (8.5%) and two patients coursed with acute urine retention (4.2%). In those with local anesthesia, one patient presented surface ecchyimosis at the site of puncture (2.3%). A significant (p ‹ 0.05) decrease in the time of operating and recovering rooms use was observed when using local anesthesia. Likewise, in these patients, pain caused by the puncture was of lesser magnitude. Patients operated under regional anesthesia presented more complications, with three hospital admittances, whereas only one complication and no hospitalizations, occurred in the group of local anesthesia.
Conclusion: The local anesthesia technique in the treatment of inguinal hernias is safer and more efficient than the regional anesthesia. Its application is simple and can be reproduced in general hospitals.
