Postoperative pain relief following inguinal hernia repair in children by wound infiltration with levobupivacaine.

The present study has been designed to compare the postoperative pain relief for inguinal hernia repair in children through wound infiltration with levobupivacaine with that provided by paracetamol administration per rectaly. This interventional study was carried out in the Department of Paediatric surgery, Mymensingh Medical College Hospital, Mymensingh and Dhaka Medical College Hospital, Dhaka, during the period from January 2009 to September 2010. A total of 120 patients were included in this study. Among them 60 patients in Group-A (study group) where post incisional wound infiltration with levobupivacain after inguinal herniotomy and before skin closure was done and 60 patients in Group-B (control group) where paracetamol was given per rectally after anesthesia induction. Both groups were followed up post operatively for 23 hours. In Group A maximum analgesic period was 8.30 hours and minimum analgesic period was 5.30 hours. On the other hand in Group B maximum analgesic period was 6.50 hours and minimum analgesic period was 4.50 hours. Duration of post operative analgesia between two groups of the patients were significant [p<0.01]. Post incisional wound infiltration with levobupivacain has significantly better efficacy to rectal administration of paracetamol with respect to providing pain relief following inguinal hernia repair in children. Longer duration of analgesic action is more achieved in the Levobupivacaine group.
