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.

Detailed 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.

Conditions

• Postoperative Nausea and Vomiting

Interventions

Type	Name	Description
PROCEDURE	ultrasound guided superficial cervical plexus block	SCP block is given using high frequency linear ultrasound probe connected to an ultrasound machine to visualize SCP posterior to the midpoint of SCM muscle. Once SCP is identified, a combination of 5 ml bupivacaine (0.5%) and 5 ml lidocaine (2%) are injected after negative aspiration followed by injection of 1 ml to confirm the area, using a 22 gauge B-bevel needle Echogenic Needle.
