Study 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.

Read the detailed 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.

    The incidence of postoperative sore throat at 0 hours and 4 hours after extubation.

    Time frame: 30 Minutes following extubation of endotracheal tube

  2. The Incidence of Post-operative sore throat

    The incidence of postoperative sore throat at 0 hours and 4 hours after extubation.

    Time frame: 4 hours following extubation of endotracheal tube

  3. The severity of Post-Operative Sore Throat

    Assessment of severity of postoperative sorethroat using scoring system, 0-No sore throat at any time since the extubation,1- Minimal sore throat,2- Moderate sore throat,3- Severe sore throat

    Time frame: 30 Minutes ,4 hours and 24 hours following extubation of endotracheal tube

  4. The incidence of of postoperative hoarseness.

    The incidence of of postoperative hoarseness at 0 hours,4 hours and 24 hours after extubation.

    Time frame: 30 Minutes ,4 hours and 24 hours following extubation of endotracheal tube

  5. The severity of postoperative hoarseness

    Assessment of postoperative hoarseness using scoring system,0- No evidence of hoarseness at any time since the extubation,1-No evidence of hoarseness at the time of interview,2-Hoarseness at the time of interview noted by patient only, 3- Hoarseness that is easily noted at the time of interview

    Time frame: 30 Minutes ,4 hours and 24 hours following extubation of endotracheal tube
