Abstract
Rationale: Cardiac surgery incisional pain can decrease inspiratory effort, alter normal respiratory mechanics, and increase the potential for post-operative pulmonary complications such as acute atelectasis.
This study aims to assess the effect of the early use of CPAP via mask therapy to treat acute atelectasis.
Methods: 72 participants who fit the inclusive criteria were included. The control group used Incentive Spirometry (IS) 15 times/hour and the trial group used CPAP for half hour every 2 hours both for 3days. Vital capacity (VC), RR, HR and SpO2 were measured after operation as baseline-test, after 12 hours, 24hours, 48 hours and posts the therapy. Failure was defined as a need for an advance therapy.
Result: 66 male and 6 female (mean ages; 57±5.3 years) were participated. 26/36 participants from CPAP group had succeed (72%) and 19/36 from IS group had succeed (53%). VC was increased significantly in CPAP group (baseline mean for IS group 1.31L and CPAP group 1.43L, post- therapy mean 1.59L and 1.88L respectively, p=0.02) (figure 1). SpO2 was decreased significantly in IS group (baseline 98.25%, 97.19%, post-therapy 96.53%, 96.83 respectively, p=0.003) and no significant different in RR and HR.
Conclusion: Early used of CPAP via mask therapy had better outcomes to treat post surgical atelectasis especially with smoker and elderly patients.
