Çocuk Hastalarda İlioinguinalL/İliohipogastrik Sinir Bloğunda Bupivakain ve Levobupivakainin Postoperatif Ağrıya Etkilerinin Karşılaştırılması: Retrospektif Çalışma

Abstract

Objective: Ilioinguinal/iliohypogastric (II/IH) nerve block added to general anesthesia is frequently used for postoperative analgesia in pediatric patients. We aimed to compare the postoperative analgesic effects of bupivacaine and levobupivacaine for II/IH nerve block for inguinal hernia repair in pediatric patients, which is not investigated previously. Materials and Methods: In this 2-year retrospective study, data were collected from the medical charts of patients that underwent unilateral inguinal hernia repair. Patients were included who received an II/IH nerve block with 0.2 mL/kg 0.5% of either bupivacaine (Group B) or levobupivacaine (Group L). Non-elective cases, age under 2 years and patients with multiple procedures were excluded. Demographic properties of the patients (age, weight, and sex), duration and side of surgery, pain scores, additional analgesic requirement and complications were documented. The chi-square test and the Mann-Whitney U test were used for statistical analysis. Results: In both groups, t he pain scores were not significantly different at post anesthesia care unit, 1, 2, 6 and 24th hours; nevertheless, the pain scores at 4th hour were significantly lower in Group L. Conclusion: II/IH nerve block added to general anesthesia is effective in inguinal region surgery of pediatric patients in postoperative pain control, and 0.5% levobupivacaine and bupivacaine had similar analgesic effect.
