Beskrivelse
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).

Antal grupper/kohorter
Kohorter og interventioner
Gruppe / kohorteGruppe / kohorte |
|---|
|
Grup 1: Standard PEEP Group
Patients undergoing gynecological laparoscopic surgery who are observed receiving a routine, fixed Positive End-Expiratory Pressure (PEEP) of 5 cmH2O during the intraoperative period.
|
|
Grup 2: Individualized PEEP Group
Following an initial lung recruitment maneuver, patients undergo individualized PEEP titration.
PEEP is initially set to 20 cmH2O and then sequentially decreased in steps of 2 cmH2O to identify the optimal level associated with the lowest driving pressure.

Tidsramme |
|---|---|---|
|
Lung Ultrasonography (LUS) Score
Tidsramme: Preoperatively (baseline), 1 hour postoperatively, and 24 hours postoperatively.
|
Atelectasis severity is assessed using a 12-zone Lung Ultrasonography (LUS) scoring system.
Each zone is scored from 0 to 3 (0=normal aeration, 3=consolidation).
The total score ranges from 0 to 36.
Higher scores indicate worse lung aeration and more severe atelectasis.

Preoperatively (baseline), 1 hour postoperatively, and 24 hours postoperatively.

Correlation Between Intraoperative Ventilation Parameters and Early Postoperative LUS Scores
Tidsramme: From the start of anesthesia until 1 hour postoperatively.

Evaluation of the relationship between intraoperative respiratory parameters (Peak Airway Pressure [Ppeak], Plateau Pressure [Pplat], and Compliance) and early postoperative lung aeration assessed by Lung Ultrasonography (LUS) in the Post-Anesthesia Care Unit (PACU).
|
From the start of anesthesia until 1 hour postoperatively.

|
Correlation Between Intraoperative Ventilation Parameters and Postoperative Oxygenation
Tidsramme: From the start of anesthesia until 1 hour postoperatively.
|
Evaluation of the relationship between intraoperative respiratory parameters (Ppeak, Pplat, and Compliance) and postoperative peripheral oxygen saturation (SpO₂) in the PACU.
|
From the start of anesthesia until 1 hour postoperatively.
|
|
Correlation Between Intraoperative Ventilation Parameters and Early Postoperative Pulmonary Complications
Tidsramme: From the start of anesthesia up to 24 hours postoperatively.
|
Evaluation of whether intraoperative respiratory parameters (Ppeak, Pplat, and Compliance) are associated with the development of clinical pulmonary complications within the first 24 hours.
|
From the start of anesthesia up to 24 hours postoperatively.
