What this trial studies

This clinical trial aims to compare intraoperative and postoperative blood loss in children undergoing adenotonsillectomy while using nondepolarizing muscle relaxants. A total of 60 children aged 3 to 7 years will be randomly assigned to receive either rocuronium bromide or no muscle relaxant during general anesthesia. The study will monitor vital signs and blood loss throughout the procedure to determine the impact of the muscle relaxant on surgical outcomes. The trial is approved by the local ethical committee and will follow strict inclusion and exclusion criteria to ensure patient safety.

Who should consider this trial

Good fit: Ideal candidates are children aged 3 to 7 years classified as ASA I or II, scheduled for adenotonsillectomy due to recurrent tonsillar infections or obstructive sleep apnea.

Not a fit: Patients with contraindications for general anesthesia, coagulation disorders, or anemia may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and reduced blood loss during adenotonsillectomy in children.

How similar studies have performed: While there is limited literature specifically addressing blood loss in adenotonsillectomy with muscle relaxants, similar studies in other surgical contexts have shown promising results.
