What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compares two ways of setting the breathing machine during gynecologic laparoscopic surgery to prevent lung collapse (atelectasis). One method uses a standard fixed pressure, while the other adjusts the pressure to each patient's lung mechanics. The researchers will use lung ultrasound to check for collapse before surgery, 1 hour after, and 24 hours after. The goal is to see which approach keeps the lungs healthier after surgery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
personalized positive end-expiratory pressure (PEEP) during mechanical ventilation
What this could lead to
If it works, this could lead to a simple way to prevent lung collapse after surgery, improving recovery for many patients.
What could go wrong
This is a small, early-stage study (72 people) looking at ultrasound scores, not long-term outcomes. The personalized method may not prove better than standard care.

Who is studied

The study population consists of adult female patients (aged 18 to 65 years) with an American Society of Anesthesiologists (ASA) physical status of I, II, or III, who are scheduled for elective gynecological laparoscopic surgeries (e.g., hysterectomy, myomectomy, sacrocolpopexy) under general anesthesia with endotracheal intubation at Ankara Etlik City Hospital.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Female patients aged between 18 and 65 years. * American Society of Anesthesiologists (ASA) physical status I, II, or III. * Scheduled for elective laparoscopic gynecological surgery (e.g., hysterectomy, myomectomy, sacrocolpopexy). * Planned to undergo general anesthesia with endotracheal intubation. * Expected surgery duration of 2 hours or more. * Body Mass Index (BMI) ≤ 35 kg/m². Exclusion Criteria: * History of moderate-to-severe Chronic Obstructive Pulmonary Disease (COPD), clinically significant interstitial lung disease, or severe restrictive lung disease. * New York Heart Association (NYHA) class III-IV heart failure, Ejection Fraction (EF) \< 35%, or severe valvular disease. * Advanced arrhythmia or hemodynamic instability (requiring high-dose vasopressor support). * History of respiratory failure requiring mechanical ventilation within the past 4 weeks. * Clinically or radiologically confirmed lower respiratory tract infection (e.g., pneumonia) within the past 1 month. * Presence of thoracic deformity, large surgical dressings, severe subcutaneous emphysema, or any condition that hinders lung ultrasound evaluation. * Pre-existing significant atelectasis or lung consolidation (defined as a score of 3 for consolidation or ≥2 zones with a score of ≥2 on preoperative LUS). * Expected inability to perform the 24-hour postoperative ultrasound measurement (e.g., due to early discharge).
