NCT ID: NCT03563963 Completed - Pharyngitis Clinical Trials

Ropivacaine vs Lidocaine in the Endotracheal Tube Cuff on Post-Operative Sore Throat

Start date: August 1, 2018
Phase: N/A
Study type: Interventional

In elective gynecology and general surgery patients age 18 and over requiring endotracheal tube (ETT) intubation, what is the efficacy of ropivacaine 0.5% vs. lidocaine 2% as the medium to inflate the ETT cuff, compared to the standard of air, in reducing the incidence and severity of POST on post-op day one?

NCT ID: NCT02405832 Completed - Sore Throat Clinical Trials

Zinc Lozenges and Their Effect on Postoperative Sore Throat Syndrome

Start date: March 10, 2015
Phase: N/A
Study type: Interventional

The objective of this study is to assess the effect of preoperative administration of oral zinc lozenges on the incidence of postoperative sore throat syndrome. When patients undergo surgery with general anesthesia, they require ventilation of their lungs with the help of a flexible tube (called an endotracheal tube) that is placed through the mouth, passing the vocal cords, and into the windpipe (trachea). This tube helps oxygenate the patient, delivers anesthetic gas to the lungs, and keeps the airways open to prevent asphyxiation. The procedure is invasive and uncomfortable, and one of the most common consequences is a sore and inflamed throat after the tube is taken out. This is termed postoperative sore throat (POST). Though the intensity and severity of sore throat varies from person to person, the reported incidence is as high as 90% of patients undergoing general anesthesia. Zinc therapy has been shown in multiple studies to reduce the severity and duration of cold symptoms, and also to up-regulate the immune system. Recent studies have shown that zinc can act as an anti-inflammatory agent and can maintain the integrity of skin and mucosal membranes (which cover the inside of the mouth and throat). The aim of this study is to evaluate the effects of giving zinc lozenges before tube placement on postoperative sore throat. After written informed consent is received in pre-op, a sealed and coded envelope with either the zinc lozenge or the placebo lozenge will be given to the patient to be administered orally, with the instruction to dissolve the lozenge by sucking on it 30 minutes prior to surgery. Upon completion of surgery and emergence from general anesthesia, the patient will be extubated and transferred to the post-anesthesia care unit (PACU). Once in the PACU, the patient will be assessed regarding the incidence and severity of POST by the study investigator using a standardized scale. The severity of POST will be graded on a 4-point scale ranging from 0 to 3; 0 being no sore throat, 1 being mild discomfort (complains only upon questioning), 2 being moderate sore throat (complains on his/her own), and 3 being severe sore throat (change in voice, hoarseness, and throat pain). This evaluation will be performed at 30 minutes, 2 hours, 4 hours, and 24 hours post-surgery, with the assessment at 4 hours being the primary outcome of the study.

NCT ID: NCT01923831 Completed - Clinical trials for Post Operative Sore Throat

Comparison of the Effect of Magnesium Sulfate and Dexamethasone on Postoperative Sore Throat After Spinal Surgery in Prone Position With Tracheal Intubation: a Double-blind, Randomized, Noninferiority Clinical Trial

Start date: August 2013
Phase: N/A
Study type: Interventional

The purpose of this study is to compare the effect of magnesium sulfate and dexamethasone on postoperative sore throat after spinal surgery in prone position with tracheal intubation.

NCT ID: NCT01305265 Completed - Dysphagia Clinical Trials

Post-operative Sore Throat as Determined by Endotracheal Tube Inflation Technique

Start date: November 2011
Phase: N/A
Study type: Interventional

The purpose of this study is to test whether the incidence of sore throat and other tracheal co-morbidities such as dysphagia and hoarseness can be lessened by use of a cuff manometer at the beginning of surgery to inflate to the proper pressure compared to the standard technique. The investigators hypothesis is that inflation of the endotracheal balloon using a cuff manometer immediately after intubation will reduce the incidence of sore throat and other tracheal co-morbidities.
