What this trial studies

This clinical trial aims to evaluate the effectiveness of high-flow nasal cannula (HFNC) oxygen therapy in preventing postoperative pulmonary complications in patients undergoing gynecologic surgery. Patients at high risk for these complications will be randomly assigned to receive either HFNC or conventional nasal cannula oxygen therapy. The primary outcome measured will be the incidence of postoperative pulmonary complications such as hypoxemia, atelectasis, and pneumonia, while secondary outcomes will include improvements in oxygenation, antibiotic use, length of hospital stay, and any adverse events related to the oxygen therapy. The study will enroll patients aged 18 to 90 with specific respiratory risk factors.

Who should consider this trial

Good fit: Ideal candidates are patients aged 18 to 90 with gynecologic neoplasms who are at high risk for postoperative pulmonary complications.

Not a fit: Patients with lung metastasis, previous lung surgery, or those undergoing segmental bowel resection may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of postoperative pulmonary complications in high-risk patients undergoing gynecologic surgery.

How similar studies have performed: Other studies have shown promising results with high-flow nasal cannula therapy in similar patient populations, suggesting potential for success in this approach.
