Using Continuous Flow Data to Predict the Course of Air Leaks After Lung Lobectomy
Background: Assessments of air leaks are usually performed subjectively, precluding the use of air leaks as an evaluation factor.

| description | Background: Assessments of air leaks are usually performed subjectively, precluding the
use of air leaks as an evaluation factor. We aimed to identify objective parameters as predictive
factors for prolonged air leak (PAL) and air leak cessation (ALC) from air flow data
produced by a digital drainage system.
Methods: Flow data records of 352 patients who underwent lung lobectomy were reviewed,
and flow data at designated intervals (1, 2, and 3 hours postoperatively [POH] and
3 times a day thereafter [06:00, 13:00, 19:00]) were extracted. ALC was defined by flow less
than 20 mL/min over 12 hours, and PAL was defined as ALC after 5 days. Cumulative incidence
curves were obtained using Kaplan-Meier estimates of time to ALC. Cox regression
analysis was performed to determine the effects of variables on the rate of ALC.
Results: The incidence of PAL was 18.2% (64/352). Receiver operating characteristic curve
analysis showed cut-off values of 180 mL/min for the flow at 3 POH and 73.3 mL/min for
the flow on postoperative day 1; the sensitivity and specificity of these values were 88.9%
and 82.5%, respectively. The rates of ALC by Kaplan-Meier analysis were 56.8% at 48 POH
and 65.6% at 72 POH. Multivariate Cox regression analysis revealed that the flow at 3 POH
(≤80 mL/min), operation time (≤220 minutes), and right middle lobectomy independently
predicted ALC.
Conclusion: Air flow measured by a digital drainage system is a useful predictor of PAL
and ALC and may help optimize the hospital course. |
