Glossopharyngeal Nerve Block for Post -Tonsillectomy Pain Relief

Status Completed

Clinical Trial 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

Clinical Trial Description

Tonsillectomy is one of the most frequent surgical procedures performed all over the world that has been identified as being severely painful especially in the adult population. Management of post tonsillectomy pain is of paramount importance in order to improve swallowing and enhance oral intake as well as to decrease the risk of dehydration, infection and secondary hemorrhage with a subsequent hastening of recovery. A variety of analgesic regimens have been implemented to alleviate post-tonsillectomy pain, however; no consensus on the ideal analgesic regimen has been yet identified. The Ultrasound (US)-guided glossopharyngeal nerve (GPN) block has been acknowledged as a feasible option for providing perioperative analgesia in tonsillectomy patients. It blocks sensory impulses from the posterior third of the tongue, palatine tonsil, and mucous membranes of the mouth and pharynx. Conventional techniques for blocking the GPN carry the risk of vascular puncture, inadvertent block of closely adjacent other cranial nerves, with increased probability of local anesthetic toxicity and even upper airway obstruction. Recently, a novel, safe, and reproducible US-guided GPN block technique has been introduced by Azman et al, which would block the GPN distally, in the tissue plane just next to the pharyngeal wall and relatively far from high risk nearby structures. ;
