Clinical Trial Summary

The aim of this randomized clinical trial is to evaluate the impact of dexmedetomidine versus ketamine soaked pharyngeal packing on postoperative sore throat in functional endoscopic sinus surgery (FESS).

Description:

A written informed consent was taken from the patients.patients will be randomly assigned to three groups of 40 subjects each; dexmedetomidine or ketamine or saline soaked pharyngeal packs were situated under direct vision. Throat packs made of gauze with a length of 20 cm and a width of 10 cm (folded transverse four times) and medications were diluted with 20 ml normal saline. The packings were placed by the surgeon blinded to the study groups. 1-Dexmedetomidine group: 75 µg dexmedetomidine soaked pharyngeal pack (Group D) putted in the posterior pharyngeal wall after induction of anesthesia and & endotracheal tube (ETT). 2-Ketamine group: 50 mg ketamine soaked pharyngeal pack (Group K) putted in the posterior pharyngeal wall after induction of anesthesia and ETT. 3-Control group: 20 ml 0.9% saline soaked pharyngeal pack (Group C) putted in the posterior pharyngeal wall after induction of anesthesia and ETT.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of postoperative sore throat (POST)	On arrival in the post anesthesia care unit, the patient was immediately evaluated for the presence of sore throat (time 0 hour) using a standardized scale. The severity of POST was graded on a 4-point scale ranging from 0 to 3; 0 being no sore throat, 1 being mild discomfort (complains only with questioning), 2 being moderate sore throat (complains on their own), and 3 being severe sore throat (change in voice, hoarseness, and throat pain). Evaluations occurred at 0, 1, 2, 4, 6, 12 and 24 hours postoperatively.	24 hour after surgery
Secondary	Postoperative nausea and vomiting (PONV) score	PONV score was assessed and documented using a Verbal Descriptive Scale, which correlates to visual analog nausea scores, with an objective measure of severity: 0 = no PONV: patient reports no nausea and has had no emesis episodes; 1 = mild PONV: patient reports nausea but declines antiemetic treatment; 2 = moderate PONV: patient reports nausea and accepts antiemetic treatment; and 3 = severe PONV: nausea with any emesis episode (retching or vomiting). The score was obtained at 0, 30, 60, 90, and 120 minutes after PACU arrival; 4 mg IV ondansetron for occurred nausea & vomiting.	2 hours postoperative
