[Respiratory complications of propofol, sevoflurane, and dexmedetomidine anesthesia for fiberoptic bronchoscopy in children aged 1 month to 3 years: a randomized trial].

Objective: To evaluate the effect of propofol, sevoflurane, and dexmedetomidine on respiratory complications in children undergoing fiberoptic bronchoscopy (FOB).

Methods: This double-blind randomized clinical trial was conducted among 120 children aged 1 month to 3 years undergoing FOB. The patients were randomized into 3 groups (=40) for anesthesia induction with sevoflurane inhalation, 1 mg/kg propofol, or 1 μg/kg dexmedetomidine before bronchoscopy, and the changes in hemodynamic parameters, sedation level, and respiratory complications during and after the procedure were assessed.

The Effect of Preoperative Combined with Intravenous Lidocaine and Ketamine vs. Intravenous Ketamine on Pediatric Patients Undergoing Upper Gastrointestinal Endoscopy.

Background: Ketamine is widely used in pediatric sedation. New studies have recommended combination therapy to reduce the side effects of ketamine.

Objectives: This study investigated the effect of adding intravenous (IV) lidocaine to ketamine on hemodynamic parameters, endoscopist satisfaction, and recovery time of children undergoing gastrointestinal endoscopy.

Comparative Study of the Effect of Oral Chloral Hydrate and Intranasal Fentanyl on Sedation in Children for Electroencephalography.

Objectives: Sedation and stability during electroencephalography (EEG) in pediatrics have high clinical importance. This study compares the sedative properties of oral chloral hydrate (OCH) and intranasal fentanyl (INF).

Materials & Methods: This study was a randomized clinical trial conducted in 2020 in Isfahan City on sixty-two pediatric candidates for EEG.

Comparative Study of the Effect of Two Different Doses of Dexmedetomidine to Prevent Emergence Agitation in Tonsillectomy in Children Aged 2 to 12 Years Old.

Background: Emergence agitation (EA) is one of the complications following anesthesia in pediatric surgery. Various drugs are used to prevent this complication, and one of them is dexmedetomidine. Choosing the right dose of this drug for the best efficiency is an important issue due to this complication.

Comparative Evaluation of Difficult Intubation Predictors in Children Under Two Years of Ages.

Background: Tracheal intubation is the most reliable way of securing an airway. Pediatric airway management is one of the significant challenges, especially for non-pediatric anesthesiologists. Early airway evaluation for detecting difficult intubation and preventing catastrophic events is necessary before anesthesia, especially in children.

Comparison of Two Dosages of Ketamine in Preventing Fentanyl-Induced Coughs in Children.

Background: Fentanyl is a short-acting drug used to induce anesthesia. Here, we aimed to compare the two doses of ketamine to prevent fentanyl-induced cough in children under general anesthesia.

Materials And Methods: This is a randomized, clinical trial which was performed in 2019 in Imam Hossein Hospital in Isfahan, Iran.
