Summary: The goal of this study is to evaluate the effects of personal versus hospital-provided dolls on preoperative anxiety and postoperative delirium in preschool children aged 3-7 years undergoing elective adenoidectomy and/or tonsillectomy. The main questions it aims to answer are: * Is the use of a personal doll or a hospital-provided doll associated with lower preoperative anxiety compared with no d...

Summary: The goal of this clinical trial is to determine whether the method of transfer to the operating room can reduce preoperative anxiety and postoperative emergence delirium in male children aged 3 to 7 years undergoing elective adenoidectomy and/or tonsillectomy. The main questions it aims to answer are: * Does transfer using a ride-on toy car reduce preoperative anxiety compared with standard stretc...

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 ...

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 ...

Summary: To observe the effects of remimazolam versus ciprofol TIVA on PRAE in pediatric tonsillectomy and adenoidectomy.

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...

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...
