Abstract :

This randomized, controlled double blind study was carried out using bupivacaine or bupivacaine with dexmeditomidine in tranversus abdominis plane block in lower abdominal surgeries to study the effectiveness of bupivacaine plus dexmedetomedine combination in post operative analgesia, to study adverse effect of bupivacaine and dexmedetomedine, to study the haemodynamic parameters in post–operative period.60 patients of either sex and age ranging from 18 to 60 years and physical status ASA risk I or II posted for routine lower abdominal surgery were divided into 2 groups(n=30), assigned to receive bupivacaine 0.25% 0.6ml/kg and 2 ml of normsal saline and other group 0.25% bupivacaine 0.6ml/kg and dexmedetomidine 0.5 mcg/kg dissolved in 2 ml of normal saline . The groups were compared in terms of pain relief, PONV score, Ramsay scale of sedation and Visual Analog Scale.In our study, the addition of dexmedetomidine to bupivacaine in TAP block led to further prolongation of analgesia, less requirement of rescue tramadol and lower VAS pain score.
