Clinical Trial Summary

Post operative sore throat after general anesthesia with endotracheal intubation is a common problem causing dissatisfaction and discomfort to the patients. The investigators want to study the effect of tramadol on postoperative sore throat in general anesthesia with endotracheal intubation.


Clinical Trial Description

Design: A prospective, randomized, controlled study. Setting: Single-center university hospital. Participants: The study included 168 patients undergoing thyroid surgery under general anesthesia with endotracheal intubation. Interventions: The patients were allocated randomly into the following 3 groups: the control group: patients will be injected intravenously 5ml of normal saline 15 minutes before anesthesia and another 5ml of normal saline was injected intravenously when the incision was washed and sutured;the pre-tramadol group: patients will be injected intravenously 5ml of tramadol (1mg / kg) 15 minutes before anesthesia and 5ml of normal saline was injected intravenously when the incision was washed and sutured. the post-tramadol group: patients will be injected intravenously 5ml of normal saline 15 minutes before anesthesia and 5ml of tramadol (1mg / kg) was injected intravenously when the incision was washed and sutured. Postoperatively, all patients will receive standard treatment. ;
