A comparison of Rectus sheath block with epidural analgesia for postoperative pain relief

Abstract

Background & Methods: The aim of the study is to study Efficacy of Rectus Sheath Block 
for Postoperative Pain Management. In epidural group before inducing anesthesia, using the 
loss of resistance approach with air between T9 & T11 spaces, the epidural catheter was 
inserted while the patient was awake. Following a negative aspiration test, a bolus dose of 10 
ml 0.125% Bupivacaine was given at the conclusion of the procedure & then every 6 hours 
until the catheter was removed 72 hours later. Patient randomised to Rectus sheath block 
group had bilateral catheters inserted in space between posterior Rectus sheath and Rectus 
muscle under direct vision at level of and 4cm lateral to superior end of laparotomy incision.
