Association of mechanical power and postoperative pulmonary complications among young children undergoing video-assisted thoracic surgery: A retrospective study
Main finding · PPCs, MP-matched cohortResult — go to the resultAdjusted odds ratio 1.43 95% CI 0.87–2.37Authors' conclusion
MP and dynamic components were not associated with PPCs in young children undergoing VATS, whereas PPCs were associated with male gender, OLV duration >90 min, less surgeon's experience and lower PEEP value.
Study context
- Population
- Children aged ≤2 years undergoing video-assisted thoracic surgery (VATS) with one-lung ventilation (OLV), single tertiary children's hospital, January 2018–February 2023
- Participants
- 581 children · 221 matched pairs
- Exposure
- High vs low mechanical power during OLV
- Outcome
- Incidence of PPCs
Methodological detailspropensity-score matched, single-centre
- Propensity-score matched
- Single-centre

Observational data: associations, not effects.
Further findings
Postoperative pulmonary complications (PPCs) by dynamic components of mechanical power (MP) (propensity score matched cohort)
| aOR (95% CI) | P value | ||
|---|---|---|---|
| Dynamic components of MPNot associated with a reduction in PPCs | 1.62 (0.85–3.10) | P = 0.15 | |
| 0.20.5125Adjusted odds ratio (log scale) |
- PPCs by dynamic components of MP (propensity score matched cohort): propensity score matched cohort, 139 matched pairs
- PPCs by dynamic components of MP (propensity score matched cohort): dynamic components mean 2.848 vs. 4.162 J min-1
MP change over the study period
- MP decreased modestly during the study period (2.63 to 1.99 J min-1)
- P < 0.0001
Risk factors for PPCs within 7 days of surgery (multiple logistic analysis)
- PPCs associated with male gender, OLV duration >90 min, less surgeon's experience and lower positive end-expiratory pressure (PEEP) value
