Effect of Superficial Cervical Plexus Block on Post Operative Nausea and Vomiting in Tympanomastoid Operations

Postoperative Nausea and Vomiting Clinical Trial

Official title: Effect of Superficial Cervical Plexus Block on Incidence and Severity of Post Operative Nausea and Vomiting in Tympanomastoid Operations in Adults, Randomized Controlled Study

Status Completed

Clinical Trial Summary

post operative nausea and vomiting are very common after tympanomastoid operations, in this study we are investigating the effect of superficial cervical plexus block on the incidence and severity of those post operative complications.

Clinical Trial Description

various treatments and regimens have been tried to overcome the problem of postoperative nausea and vomiting after tympanomastoid surgery. superficial cervical plexus block seems so promising in this regards as it may reduce the incidence and severity of PONV through 3 mechanisms: primarily through blocking vagal afferents to the middle ear which mediate the vomiting reflex, and secondarily through decreasing pain which aggravates PONV, and finally through decreasing intra and post operative opioid consumption due to adequate analgesia which in turn avoids opioids side effects including PONV.

the study group will receive superficial cervical plexus block while the control will receive the same block while given placebo instead of (lidocain/bupivacaine mixture) incidence and severity of PONV will be recoded according to a scale to find the difference between both groups. ;
