Evaluating the Effect of Pressure-Controlled Versus Volume-Controlled Ventilation Modes on Intraoperative Bleeding in Rhinoplasty: A Randomized Clinical Trial.

Background: Intraoperative bleeding is one of the major challenges in rhinoplasty.

Objectives: This study aimed to evaluate the effect of pressure-controlled ventilation (PCV) versus volume-controlled ventilation (VCV) modes on intraoperative bleeding during rhinoplasty.

Methods: In a double-blinded randomized clinical trial, 58 candidates for rhinoplasty were randomly assigned to the PCV or VCV groups.

The Effect of Phenylephrine Nasal Drops on Surgical Bleeding in Children Underwent Cleft Palate Surgery: A Randomized Clinical Trial.

Background: Cleft lip and palate are birth defects due to a lack of proper formation of the lip or mouth. Controlling bleeding during cleft lip and palate surgeries is very important.

Objectives: This study aimed to evaluate the effect of phenylephrine nasal drops on bleeding during and after cleft palate repair surgery in children.
