The present study has been designed to compare the intensity of postoperative pain in children by wound infiltration with levobupivacaine with that provided by paracetamol administration per rectaly. This intervention study was carried out at the department of paediatric surgery, Mymensingh Medical College Hospital, Mymensingh and Dhaka Medical College Hospital, Dhaka, during the period of 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 before skin closure was done and 60 patients in Group B (control group) where paracetamol was given per rectally after induction of anaesthesia. Both groups were followed up post operatively for 23 hours. The intensity of post operative pain relief following inguinal hernia repair in children by wound infiltration with levobupivacaine is significantly higher than rectal administration of paracetamol.
