What this trial studies

This study compares the effectiveness of propofol infusion versus dexmedetomidine infusion in reducing the incidence of postoperative nausea and vomiting (PONV) in patients undergoing ureteroscopic procedures under spinal anesthesia. It focuses on patients aged 18 to 60 years who have multiple risk factors for PONV, such as being female, having a history of PONV, and being non-smokers. The study aims to understand the mechanisms by which these medications may alleviate nausea and vomiting post-surgery, considering the physiological effects of regional anesthesia on the body. By analyzing the outcomes, the study seeks to improve patient recovery experiences and satisfaction.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 18 to 60 years scheduled for ureteroscopic procedures who have more than one risk factor for postoperative nausea and vomiting.

Not a fit: Patients with contraindications for spinal anesthesia or those with a history of allergy to propofol or dexmedetomidine may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of postoperative nausea and vomiting, leading to faster recovery and higher patient satisfaction.

How similar studies have performed: Previous studies have explored the effects of propofol and dexmedetomidine on PONV, indicating potential benefits, but this specific comparison in the context of ureteroscopic procedures is relatively novel.
