NCT05435833

Brief Summary

The aim of the present study is to evaluate the efficacy and safety of Ultra-sound guided submandibular parapharyngeal glossopharyngeal nerve block as regards time for first need of analgesic as a primary outcome as well as pain score, total postoperative analgesic requirement, and incidence of complications as secondary outcomes

Outcome Measures

Primary Outcomes (1)

  • Onset of 1st analgesic request

    the time to first analgesic request will be recorded

    up to 24 hours postoperative

Secondary Outcomes (2)

  • Pain score

    at 30 minutes, 2 hours, 6 hours, 12 hours, and 24 hours postoperative

  • Postoperative rescue analgesic consumption

    up to 24hours postoperative

Study Arms (2)

Group I (glossopharyngeal nerve block group)

EXPERIMENTAL

bilateral ultrasound guided GPN block will be performed after induction of anesthesia and pre incisional by an experienced anesthesiologist

Procedure: bilateral ultrasound guided GPN block

Group II(Control group)

NO INTERVENTION

general anesthesia alone (no block)

Interventions

a linear high frequency ultrasound probe will be initially positioned over the hyoid bone in the transverse plane, then the probe will be rotated to keep in line with the mandibular angle and the pharyngeal wall is identified by US. Using an in plane approach, a 22 G ,5 cm needle will be advanced till it reaches just superficial to the pharyngeal wall and 2.2 ml of 0.25% bupivacaine will be injected.

Group I (glossopharyngeal nerve block group)
