Background and study aims
This study will investigate a method that aims to reduce the intensity of pain in children undergoing Ear, Nose, and Throat (ENT) surgical procedures of removal of the palatine tonsils (tonsillectomy) and adenoid (adenotomy) at the University Hospital in Wroclaw. Pain caused by surgery is the main reason for a child's discomfort period following the surgery. Pre-emptive pain relief is a procedure that is initiated before the onset of the pain stimulus and leads to blocking the pain signal, coming from the surgical wound.

The aim of this study is to evaluate how effective pre-emptive pain relief is in preventing postoperative pain, after ENT surgical procedures in children.

Who can participate?
Healthy children between the ages of 3 and 17 years, who are qualified for surgical treatment in an ENT clinic

What does the study involve?
Participants will be allocated to one of two groups, with an equal chance of being in either group (like tossing a coin). The participants in the first group will be given a pain relief drug (paracetamol) before surgery, in addition to the standard preparation for surgery. The dose of the drug will be adjusted according to the child's weight. The participants in the second group will be given an identical looking treatment with no active medicine before surgery, in addition to the standard preparation for surgery. After surgery participant pain levels will be assessed.

What are the possible benefits and risks of participating?
Paracetamol is a drug that has long been widely used for the treatment of pain in home and hospital settings. The device used to measure pain via skin conductance is noninvasive and painless. The use of pre-emptive analgesia will allow to individually adjust pain therapy to the child's needs. The results of the study will answer the question of whether this method has an effect on the reduction of postoperative pain in children. It is hoped that effectively treated pain will contribute to an increase in comfort for the child hospitalized at the department and a reduction in the length of hospitalization.

Where is the study run from?
Wroclaw Medical University (Poland)

Scientific titleThe effect of Pre-Emptive Analgesia on the Postoperative pain IN pediatric otolaryngology: a randomized, controlled trial
Study acronymP-EAPIN
Study objectivesThe administration of pre-emptive analgesia reduces the severity of postoperative pain in children
Ethics approval(s)Approved 16/08/2018, Ethical Committee of the Medical University of Wrocław (Pasteura 1, 50-367 Wrocław, Poland; +48717841014; bioetyka@umed.wroc.pl), ref: KB–459/2018
Health condition(s) or problem(s) studiedPostoperative pain in children
InterventionThe study will randomly allocate a patient to an intervention or control group, using permuted block randomization. The intervention group will receive pre-emptive analgesic paracetamol orally (15 mg/kg) and the control group will receive a placebo in addition to midazolam (0.5 mg/kg) as premedication. All children are administered sevoflurane gas, intravenous propofol (between 2 and 4 mg/kg), and fentanyl (2 mcg/kg). During the surgery, all patients receive intravenous dexamethasone (0.2 mg/kg) and nalbuphine (0.2 mg/kg) as standard perioperative analgesia.
