Transversus abdominis plane (TAP) block is a fascial plane block providing post-operative analgesia in patients undergoing surgery with infra-umbilical incisions. We evaluated analgesic efficacy of TAP block with ropivacaine for 24 h after caesarean section through a Pfannenstiel incision.
Sixty patients undergoing caesarean section under spinal anaesthesia were randomised to undergo TAP block with ropivacaine ( n = 30) versus control group ( n = 30) with normal saline, in addition to standard analgesia with intravenous paracetamol and tramadol. At the end of the surgery, ultrasound-guided TAP plane block was given bilaterally using ropivacaine or normal saline (15 ml on either side). Each patient was assessed post-operatively by a blinded investigator at regular intervals up to 24 h for visual analogue score (VAS) and requirement of analgesia. SPSS version 18.0 software was used. Demographic data were analysed using Student's t-test and the other parameters using paired t-test.
