Abstract

Transversus abdominis plane (TAP) block is effective as part of multimodal pain management following Infra umbilical surgeries in absence of advance modern technical tools, as it is a simple clinical anatomical landmark procedure. Aim: TAP was used to compare the duration of analgesia produced by two drugs fentanyl and dexmedetomidine as adjuvants to ropivacaine. It also looked at the advantage of this block in reducing the consumption of rescue analgesia postoperatively. Methods: This is a randomized comparative study done from January 2021- August 2022 in which 60 patients were enrolled. The patients were randomly assigned to one of two groups of 30 patients each. Group A- Combination of Inj. Fentanyl (25 mcg) + Ropivacaine (0.375%)-. Total volume = 20 ml (each side). Group B- Combination of Inj. Dexmedetomidine (25 mcg) + Ropivacaine (0.375%) – Total volume = 20 ml (each side). The study parameters were: comparison of time duration of analgesia measured via ten point numerical pain score measured at 3, 6, 9, 12, and 24 hrs postoperatively, consumption of rescue analgesia, demand for rescue analgesia and any side effects (hypotension, bradycardia and fall in oxygen saturation)
