Comparing the Analgesic Efficacy of Local Wound Infiltration by Bupivacaine and Tramadol in Children Undergoing Inguinal Hernia Repair.
Pak J Med Health Sci Jan ;13(1):344-7.

Aim: To compare the time for first analgesic requirement after local wound infiltration with bupivacaine and tramadol in children undergoing inguinal hernia. Methods: A total number of 122 children having age 4-12 years who were planned to undergo elective inguinal hernia repair were included from Oct-2018 to Jan-2019. Patients were randomly allocated to tramadol group and bupivacaine group. At the end of surgery, patients in Group T received skin infiltration by Inj. Tramadol 2 mg/kg diluted in 10cc distilled water while patients in Group B received Inj. Bupivacaine 1mg/kg diluted in 10 cc distilled water. Pain score by Wong Baker Faces Scale at 1/2 hour, 1 hour, 2 hour, 4 hour and 6 hour interval were noted by a blinded observer and 3rd figure was taken as significant to give rescue analgesia Results: Mean age of the studied patients was 7.72+/-2.52 years. There were 76 (62.30%) male and 46 (37.70%) female children. Mean weight of children with inguinal hernia repair was 18.82+/-5.61 Kg. Mean duration of surgery was 45.66+/-4.71 minutes. Mean time of analgesia was 6.90+/-0.76 hours in tramadol group and 5.75+/-0.94 hours in bupivacaine group (p-value <0.001).Conclusion: Local wound infiltration with tramadol provides a longer time for first analgesic requirement as compared to the bupivacaine in children undergoing inguinal hernia repair.
