Background and study aims
An adenotonsillectomy is a common surgical procedure in which the small lumps of tissue at the back of the throat and nose (tonsils and adenoids) are removed. The tonsils and adenoids are part of the immune system they are not essential, and their removal does not damage the immune system in any way. The procedures are very simple and safe, and one of the most common complications is the agitation the child feels when they wake up from general anesthesia (being put to sleep for the operation). This puts a child at risk of hurting themselves, a longer stay in hospital, extra nursing care requirements, the family not being happy with the treatment and increased costs. In order to prevent this problem, giving extra medications as well as the general anesthesia is the standard approach. The aim of this study is to compare the effects of two commonly used drugs on agitation upon waking from general anesthesia (emergence agitation).
Who can participate?
Patients aged between 2-12 years who are having their tonsils and adenoids removed.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group are given dexmedetomidine (a sedative) mixed with normal saline (salt water) through a drip over a 10 minute period. Those in the second group receive tramadol (a pain-reliever) mixed with normal saline (salt water) through a drip over a 10 minute period. Participants in both groups are put to sleep for their surgery the same way and have their vital signs (such as heart rate, breathing and blood pressure) measured throughout surgery. Participants in both groups are then observed by clinical staff in the recovery area for an hour after their surgery to look for signs of emergence agitation.
What are the possible benefits and risks of participating?
There are no direct benefits or risks involved with taking part in this study.

| Scientific title | Tramadol vs dexmedetomidine for emergence reaction control in pediatric patients undergoing adenotonsillectomy with sevoflurane anesthesia: Prospective randomised controlled clinical study |
| Study objectives | The aim of this study is to evaluate the hypothesis that tramadol would control emergence agitation of sevoflurane as efficient as dexmedetomidine in pediatric patients undergoing adenotonsillectomy. |
| Ethics approval(s) | Erciyes University Research Ethics Committee, 01/03/2011, ref: 2011/135 |
| Health condition(s) or problem(s) studied | Postoperative pain after adenotonsillectomy |
| Intervention | Patients are randomised to one of two groups according to a computer generated random numbers table. Group 1: After intubation, patients receive 1 µg/kg dexmedetomidine diluted in saline (2 ml of dexmedetomidine and 8 ml of saline) administered as a single IV dose over a 10 minute period. Group 2: After intubation, patients receive 2 mg/kg tramadol diluted in saline 4 ml of tramadol and 6 ml of saline) administered as a single IV dose over a 10 minute period. Standard anesthesia monitoring includes electrocardiogram, noninvasive blood pressure, pulse oximetry, and inspiratory and expiratory gas concentrations are applied to all the patients in both group during the surgery. Heart rate (HR), mean arterial pressure (MAP), peripheral oxygen saturation (SpO2), and minimum alveolar concentration (MAC) are also recorded before induction (baseline), at induction and every 5 minutes after induction during the procedure. After the end of the procedure at the post anesthesia care unit (PACU) the intensity of pain is assessed using a modified Hannallah pain score and observational pain score (OPS), pediatric anesthesia emergence delirium (PAED) scale, Ramsay sedation score (RSS). HR, MAP, SpO2 are measured and recorded on arrival to PACU and 5, 10, 15, 30, 45, 60 minutes after arrival to PACU. Any adverse effects such as vomiting, airway obstruction, laryngospasm or bronchospasm are also recorded. |
