Purpose of study: This study was done to evaluate transdermal diclofenac patch as pre-emptive analgesic in providing post-operative analgesia in Hernia correction surgeries, compared to intramuscular diclofenac injection.
Methodology: The study was cross sectional by using questionnaire in 60 healthy adult subjects of either sex undergoing Hernia correction surgery under spinal anaesthesia .The subjects were assigned into two groups (Group DI and Group DP) by computer generated randomization table to receive intramuscular diclofenac 75mg or transdermal diclofenac patch 100mg immediately after spinal anaesthesia. The patients were monitored for pain at 2,6 and 12 hours post-operatively using Visual Analogue Scale. Duration of analgesia and request for rescue analgesic (Tramadol 2mg/kg) were noted in both the groups. The study ended when patients had a VAS > 8 or at first request for analgesic.
Results: The mean duration of analgesia in group DI was 8.9±2.16 hours and in the group DP was 10.28±2.54 hours.
Conclusion: Preoperative application of single dose of transdermal diclofenac patch 100mg provides prolonged analgesia compared to single dose of intramuscular diclofenac 75 mg for acute post-operative pain, without any significant side effects.
