Tracheal intubation is a medical procedure that involves the insertion of a tube into the trachea, which is the airway that leads from the mouth and nose to the lungs. This procedure is done to help patients breathe better, to deliver anesthesia during surgery, or to remove secretions from the lungs.
While tracheal intubation is a common and important medical intervention, it can also lead to complications, such as a sore throat, cough, and hoarseness, after the procedure. These complications can be uncomfortable and may delay a patient's recovery.
To minimize these complications, researchers have been studying ways to prevent them. One potential approach is gargling with licorice extract, ketamine, and magnesium sulfate before tracheal intubation. This clinical trial aims to investigate whether this approach can effectively prevent postoperative sore throat, cough, and hoarseness.
Understanding the potential complications of tracheal intubation and ways to prevent them can improve patient outcomes and make the procedure safer and more comfortable for patients.
The trial involved 105 patients who were having surgery that required a tube to be inserted into their throat. The patients were randomly divided into three groups. Each group was asked to gargle with a different substance before the surgery: ketamine, licorice extract, or magnesium sulfate. The patients were asked to gargle for 15 seconds twice, and then spit out the substance.
After the surgery, the patients were monitored for any signs of sore throat, coughing, or hoarseness. The monitoring started right after the tube was removed from their throat and continued for 45 minutes. The patients were also asked about any soreness, coughing, or hoarseness they experienced 2, 4, 8, 12, and 24 hours after the surgery.
