Abstract


Prinsip lung protective ventilation merupakan strategi ventilasi intraoperasi yang direkomendasikan untuk mencegah komplikasi paru pascaoperasi. Penelitian ini bertujuan mengetahui efek pemberian PEEP 5 cmH2O terhadap nilai FEV1 dan FVC pada pasien pascaoperasi ortopedi. Penelitian dilakukan terhadap 54 pasien yang dibagi menjadi 2 kelompok, yaitu kelompok PEEP 5 dan kelompok kontrol (PEEP 0). Penelitian eksperimental ini menggunakan desain single-blind randomized controlled trial dan melibatkan 54 pasien yang dilakukan operasi ortopedi di RSUP Dr. Hasan Sadikin Bandung pada bulan Oktober 2021–Januari 2022. Analisis statistik menggunakan uji T tidak berpasangan dan Uji Mann-Whitney. Hasil penelitian ini menunjukkan bahwa pada kelompok PEEP 5 terjadi penurunan nilai FEV1 lebih rendah dengan rerata –0,17±0,123 dibanding dengan kelompok kontrol (PEEP 0) sebesar -0,49±0,237. Pada kelompok PEEP 5 terjadi penurunan nilai FVC yang lebih rendah dengan rerata -0,20±0,132 dibanding dengan kelompok kontrol (PEEP 0) sebesar -0,60±0,23. Terdapat perbedaan yang signifikan secara statistik antara kelompok PEEP 5 dan PEEP 0 (p<0,05). Simpulan penelitian ini adalah perubahan penurunan nilai FEV1 dan FVC pada pasien pascaoperasi ortopedi dengan pemberian PEEP 5 cmH2O lebih rendah dibanding dengan kelompok kontrol (PEEP 0).

 

Effects of Positive End Expiratory Pressure cmH2O on Changes in Forced Expiratory Volume in 1 Second and Forced Vital Capacity Values in Post Orthopedic Surgery Patients

The principle of protective lung ventilation is the recommended ventilation strategy to prevent postoperative pulmonary complications. This study aimed to determine the effect of Positive End Expiratory Pressure (PEEP) 5 cmH2O on Forced Expiratory Volume in 1 second (FEV1) and Forced Vital Capacity (FVC) post orthopedic surgery patients. The study was conducted on 54 patients divided into two groups: the PEEP 5 group and the control group (PEEP 0). This experimental study used a single-blind randomized controlled trial design involving 54 patients undergoing orthopedic surgery at dr. Hasan Sadikin General Hospital Bandung between October 2021–January 2022. Statistical analysis was performed using the unpaired T-test and Mann-Whitney test. Study results revealed that in the PEEP 5 group, there was a smaller decrease of FEV1 values, with an average of -0.17±0.12 compared to the control group (PEEP 0) of -0.49±0.23. In the PEEP 5 group, there was a smaller decrease in the FVC value with an average of -0.20 ± 0.13 compared to the control group (PEEP 0) of -0.60±0.23. There was a statistically significant difference between the PEEP 5 and PEEP 0 groups with (p<0.05). This study concludes that the decrease in FEV1 and FVC values in post orthopedic surgery patients with PEEP 5 cmH2O is lower than the control group (PEEP 0).
