Small study tests best way to help patients breathe during prostate surgery
NCT ID NCT07462689
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study looked at 58 men having robotic prostate surgery. Researchers compared two breathing support methods—using a steady low pressure (PEEP) alone or adding a deep breath maneuver (ARM)—to see which kept oxygen levels better during surgery. The goal was to find safer ventilation strategies for this type of operation.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help anesthesiologists choose better ventilation methods to keep oxygen levels stable during robotic prostate surgery.
- What could go wrong
- This is a small, completed trial with only 58 participants. Results may not apply to all patients or surgeries, and no new treatment is being tested.

Inclusion Criteria: * Adult patients with American Society of Anesthesiologists (ASA) physical status I-III scheduled for elective robot-assisted radical prostatectomy under general anesthesia Exclusion Criteria: * uncontrolled asthma, chronic obstructive pulmonary disease (defined as a forced expiratory volume in 1 second to forced vital capacity ratio \<60% or forced expiratory volume in 1 second \<60% of the predicted value) * hypoxemia (oxygen saturation \<90% on room air) * left ventricular ejection fraction \<50% * hypotension (systolic blood pressure \<90 mmHg) * body mass index ≥30 kg/m² * conversion to open surgery, or intraoperative events that precluded protocolized ventilation.
