Perioperative medicine & outcomes
Lung ultrasound for evaluating perioperative atelectasis and aeration in the post-anesthesia care unit
Authors' conclusion
Lung ultrasound enables early postoperative evaluation of atelectasis and lung aeration, which are closely associated with postoperative oxygenation.
Study context
- Population
- Patients undergoing elective non-cardiothoracic surgery under GA, lung ultrasound in post-anesthesia care unit (PACU)
- Participants
- 93 consecutive patients
- Outcome
- Atelectasis on lung ultrasound in PACU
- Follow-up
- 5 min after PACU admission
Methodological detailsconsecutive patients
- Consecutive patients
Main finding
As reported in the abstract
Atelectasis in ≥1 of 12 segments
32
34%
Atelectasis in ≥3 segments
12
13%
Observational data: associations, not effects.
Further findings
Lung ultrasound score ≥ 5 vs < 5
- Higher BMI and lower PaO2 before PACU discharge with scores ≥ 5
Atelectasis and patient factors/oxygenation
- Patients with atelectasis had higher BMI and lung ultrasound scores
- ≥ 2 regions of atelectasis associated with lower PaO2
Multivariate analysis
- BMI, intraoperative body position and sex independently correlated with lung ultrasound scores
- Age and lung ultrasound scores independently correlated with hypoxemia
