Supplemental High Flow Oxygen to Reduce Infections in Obese Gynecological Cancer Patients
A study testing Supplemental oxygen therapy in people with Supplemental Oxygen and Gynecological Cancer, run by National and Kapodistrian University of Athens at 1 site in Greece.
Trial summary
The incidence of surgical-site infection (SSI) and complications related to wound healing reaches 10-20% of gynecological cancer patients. Each complication may dramatically prolong the hospitalization period and increase the economic burden of hospital care. Read more about this study

About this study
Official title: Supplemental Administration of High Flow Oxygen to Enhance Postoperative Recovery and Reduce Infections in Obese Gynecological Cancer Patients
The incidence of surgical-site infection (SSI) and complications related to wound healing reaches 10-20% of gynecological cancer patients. Each complication may dramatically prolong the hospitalization period and increase the economic burden of hospital care. Appropriate wound care and tissue oxygenation are of special importance for wound healing. Assuming adequate perfusion, the easiest, safest, and most effective way to improve tissue oxygenation is to increase the fraction of inspired oxygen. However, there is considerable controversy as to whether supplemental oxygen actually reduces SSI and healing-related complications as to date, there is absence of relevant data.
Read the detailed description
This study aims to investigate the prophylactic value of postoperative oxygen administration against the development of wound infections in obese gynecological oncology patients undergoing laparotomy for the treatment of endometrial or ovarian cancer. At the same time, the factors that lead to an increase in this risk will be outlined.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Supplemental oxygen therapyBehavioural
In this grou participants will receive supplemental oxygen in the form of a Venturi mask upon low oxygen saturation in oximetry (SaO2<95%) and a nasal oxygen mask in all other cases during the first 2 postoperative days
| Study group | Role | What they receive |
|---|---|---|
| Supplemental oxygen | Active comparator | This group will receive supplemental oxygen in the form of a Venturi mask upon low oxygen saturation in oximetry (SaO2<95%) and a nasal oxygen mask (in case of normal oxygen saturation) for the first 2 postoperative days Receives: Behavioral: Supplemental oxygen therapy |

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jan 2025; AzTrials last refreshed its copy on 8 Nov 2026.
