Summary: This randomized controlled trial will evaluate the effect of bispectral index (BIS)-guided anesthesia on postoperative nausea and vomiting (PONV) in children aged 3-8 years undergoing elective adenoidectomy. Fifty-eight patients will be randomized to BIS-guided anesthesia (target 40-60) or standard clinical management. The primary outcome is PONV incidence within 24 hours. Secondary outcomes inclu...

Summary: This randomized controlled trial aims to compare the interaction of methylprednisolone and dexamethasone with sugammadex in pediatric patients undergoing adenoidectomy and/or tonsillectomy. The primary objective is to evaluate the effect of these corticosteroids on the reversal time of rocuronium-induced neuromuscular block by sugammadex. Secondary outcomes include postoperative pain, nausea and v...

Summary: The goal of this observational study is to evaluate the effect of adenoid hypertrophy on the masseter muscle in children aged 3 to 8 years. The primary objectives are: * To assess whether adenoid hypertrophy affects the thickness or structure of the masseter muscle. * To determine whether there is a measurable difference in masseter muscle characteristics between children with and without adenoid ...

Introduction: Patients undergoing surgery under general anaesthesia are frequently intubated with an endotracheal tube (ETT). The safety margin of ETT cuff pressure is between 20-30 cmH2O. Inadequately inflated cuff (\<20 cmH2O) may cause secretions in the mouth, foreign bodies, bleeding due to surgery to escape into the trachea and/or air leakage. As a result of air leakage, the effect of mechanical ventilatio...

Summary: The goal of this clinical trial is to learn the effect of intravenous esketamine in postoperative negative behavior changes in children compared to placebo (a look-alike substance that contains no drug). It will also learn about the effect of esketamine in emergence delirium. The main questions are: Dose esketamine lower the incidence of postoperative negative behavior changes compared to placebo?...

Summary: Tonsillectomy and/or adenoidectomy are common surgeries in children. Authors report how distressed children and their families are by perioperative processes. Fear of the unknown can put a strain on the preoperative period, while pain and other possible complications such as fever, vomiting, restricted oral feeding or bleeding can create difficulties in postoperative home management. Parental anxi...

Summary: Although tonsillectomy is one of the most commonly performed surgeries, a review of literature reveals no articles dealing with the study of intraoperative blood loss in tonsillectomy and adenotonsillectomy according to the use of nondepolarizing muscle relaxants. The primary aim of our trial will be to compare blood loss in the operating theatre and postoperatively in two groups of children havin...

Summary: The suprazygomatic maxillary nerve (SZMN) block is a well-established, safe and effective regional technique for pain management following cleft palate procedures. However, it has not been studied for patients undergoing tonsillectomy and adenoidectomy (T\&A) procedures. The goal of this study is to determine whether the SZMN block can be utilized to improve pain control and decrease morbidity in ...

Objectives: To assess the cardiovascular outcomes of children with obstructive sleep apnoea (OSA) at a mean of 5 years after they had undergone adenotonsillectomy (AT), compared to OSA children who did not undergo AT, and normal controls without OSA. Hypothesis to be tested: (1) children with OSA underwent AT would have lower cardiovascular risks, namely lower ambulatory blood pressure (ABP), better cardiac f...

Summary: Efficacy of partial adenoidectomy versus total adenoidectomy regarding rate of recurrence and relief of nasal obstruction.

Background: The Eustachian Tube (ET) is a mucosa-lined connection between the nasopharynx and the middle ear cavity. It is believed to have three functions: 1) ventilation of and pressure equalization in the middle ear cavity, 2) mucus drainage from the middle ear, and 3) protection against sound and infection from the nasopharynx1. In adults, Eustachian Tube Dysfunction (ETD) can cause complaints from one or...

Summary: Suspension laryngoscopy is a common procedure during adenoteonsillectomy (removal of adenoids and tonsils), that consists of extending the patient's neck to allow better visualization of the tonsils. Previous studies on suspension larygnoscopy have shown that the time to maximum force during this procedure predicts complications such as pain, tounge swelling and opioid requirements. Moreover, moni...
