What to expect

No one can promise a trial will help you personally — that is what the research is trying to find out.

What participation involves

Not stated in the study description — ask the study team about visits and procedures.

Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

In plain language

This study tests how extra oxygen affects breathing as people recover from general anesthesia, medicine that keeps them asleep during surgery. It is for people having robot-assisted surgery to remove a kidney or prostate through small cuts. Researchers will watch breathing for 90 minutes after the breathing tube is removed.

In this randomized-controlled trial the investigators will examine the effect of oxygen supplementation on the recovery of breathing for 90 minutes in the immediate post-anesthesia period starting from extubation of the trachea.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Who can join

  • Have an ASA physical status rating of I–III, meaning you are healthy or have mild to severe illness.
  • Have a body mass index (BMI) below 40. BMI is a measure based on height and weight.
  • Are scheduled for robot-assisted surgery through small cuts to remove a kidney or prostate.

Who can't join

  • Have COPD, a long-term lung disease that makes breathing hard.
  • Have a severe brain or nerve, heart or lung, or mental health disorder, or an untreated thyroid disorder.
  • Have long-term pain treated with opioid pain medicines.
  • Have a hematocrit below 30% at the end of surgery. Hematocrit is the share of your blood made up of red blood cells.
  • Lose enough blood during surgery to need a transfusion of blood or blood products.

Simplified for readability. The official criteria below are what the study team uses.

Official eligibility criteria

Inclusion Criteria: * American Society of Anesthesiologists (ASA) physical status I-III * Body mass index (BMI) less than 40 kg/m2 * Scheduled to undergo robotic-assisted radical laparoscopic nephrectomy or prostatectomy. Exclusion Criteria: * Patients with a diagnosis of chronic obstructive pulmonary disorder (COPD), severe neurological, cardiopulmonary, psychiatric, or untreated thyroid disorder * Chronic pain condition that is being treated with opioids * Patients with a hematocrit lower than 30% at the end of surgery, or those with an excessive blood loss, requiring transfusion of blood products during surgery.
