What this trial studies

This observational study investigates the role of heart rate variability (HRV) as a potential biomarker for predicting postoperative nausea and vomiting (PONV) in female patients undergoing elective laparoscopic cholecystectomy. By measuring HRV before and after surgery, the study aims to determine its predictive value regarding the incidence and severity of PONV. A total of 110 participants will be enrolled, focusing on those who meet specific inclusion criteria, such as being non-smokers and in good physical health. The findings could enhance understanding of PONV risk factors and improve patient management.

Who should consider this trial

Good fit: Ideal candidates are female patients aged 18 to 65 scheduled for elective laparoscopic cholecystectomy who are non-smokers and in good health.

Not a fit: Patients with a history of cardiovascular, neurological, or gastrointestinal diseases, or those on medications affecting HRV may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better prediction and management of postoperative nausea and vomiting, improving patient comfort and recovery.

How similar studies have performed: While the predictive role of HRV in PONV is a novel approach, similar studies have suggested potential benefits, but this specific application remains largely untested.
