Trial Outcomes & Findings for The Effect of Prophylactic Ketorolac on Sore Throat After Thyroid Surgery (NCT NCT02039427)

NCT ID: NCT02039427

Last Updated: 2017-08-28

Results Overview

The investigator asked scales to patients at 1, 6 and 24h after extubation. POST was defined as discomfort at larynx or pharynx at rest and during swallowing after surgery and was assessed using a 4-grade scale (0-3) based on verbal responses to questions: 0, none; 1, mild (less severe than with a cold); 2, moderate (similar with a cold); 3 severe (more severe than with a cold) ● Incidence of sore throat : if patient rates sore throat scale more than 1, investigator will record as positive symptom.

Participant Flow

This study was conducted Yeungnam University Hospital in South korea from Oct. 2013 to Oct. 2015. One hundred and ninety - two female adults aged between 20 and 65 years, ASA physical status I or II scheduled for elective primary thyroidectomy under general anesthesia were enrolled.

Patients with a airway problem, recent upper respiratory tract infection, obese, inflammation or hemorrhage in the upper gastrointestinal tract, use of NSAID or steroid medication, allergy to the general anesthetic used in this study were excluded.

SECONDARY outcome

Timeframe: at 1, 6 and 24 hours after thyroidectomy

The investigator asked scales to patients at 1, 6 and 24h after extubation. PH was assessed using a 4-grade scale (0-3): 0, none; 1, mild (noticed by the patient only); 2, severe (obvious to observer); 3 aphonia (silence of voice) ● Incidence of hoarseness: If patient exhibit hoarseness scale more than 1, investigator will record as positive sign
