A Prospective randomized single blinded study to compare the effect of serratus anterior plane block on postoperative analgesia after Mastectomy

The use of ultrasound in regional anaesthesia has facilitated the visualisation of anatomical structures,needle advancement and the spread of local anaesthetic.This has led to the further refinement of fascial plane blocks,in which the local anaesthetic is injected into a tissue plane rather than around individual nerves.Introduces by Blanco et al,Serratus Anterior Plane block is a novel form of ultrasound guided regional anaesthesia fascial plane block that can achieve paraesthesia of the hemithorax.This study evaluates the analgesic efficacy of Serratus Anterior Plane block on acute pain after Mastectomy.The study participants are divided into two groups. Group-A is control group where no block will be given, Group-B is Serratus Anterior Plane block group, these participants after intubation they will be getting block under ultrasound guidance.At the end of the surgery, post extubation following transfer to PACU,both groups will be getting Intravenous Inj.Morphine using Patient Controlled Analgesia pump. The primary outcome of this study is to compare cumulative opioid consumption in both groups. The secondary outcome is to assess the analgesic efficacy using Visual Analog Scale.
