Perbedaan Jumlah Bakteri pada Sistem Closed Suction dan Sistem Open Suction pada Penderita dengan Ventilator Mekanik
ABSTRACT

Background: Bacterial colonization is identified as major mechanism in the pathogenesis of Ventilator Associated Pneumonia. Application of suction is one of the non -pharmacologic strategy to decrease number of Ventilator Associated Pneumonia (VAP) incidence. Since its introduction, closed tracheal suction system (CSS) has been reported offering microbial advantage over conventional open closed suction system (OSS).

Objective: This research was aimed to identify the difference of bacterial count pre and post-intervention between CSS and OSS group.

Method: This is a Randomized Control Group Pretest-Postest Design with Consecutive Sampling Approach. Number of subjects are 30 patients in whom equally distributed into 2 intervention groups; (15 closed suction system, 15 open suction system). Oral suction was performed every 12 hours for consecutive 48 hours. Secret of trachea was collected pre and post-intervention to identify for bacteria count and profile. Statistic analysis was conducted using Wilcoxon and Mann-Whitney test.

Result: Bacterial count was significant different in group 1 (p=0,0010. Significant result was also identified in group II (p=0,005). Comparatively, pre and post intervention between group I and II was not significantly different (p=0,008).

Conclusion: Closed suction system’s application in mechanically ventilated patients was confirmed with decrement in number of bacteria significantly. Comparatively, closed suction was not significantly better than OSS. However this research that although did not differ significantly, CSS’ performance was better than OSS.

ABSTRAK

Latar belakang: Kolonisasi bakteri didefinisikan sebagai mekanisme utama di dalam patogenesis Ventilator Associated Pneumonia (VAP). Penggunaan suction merupakan salah satu strategi dalam mengurangi jumlah kejadian Ventilator Associated Pneumonia (VAP). Closed tracheal suction system (CSS) dilaporkan memiliki keuntungan dalam aspek mikrobiologi bila dibandingkan dengan open closed suction system (OSS).

Tujuan: Mengetahui efektivitas penggunaan closed suction system dibandingkan dengan open suction system pada penderita dengan ventilator mekanik.

Metode: Merupakan penelitian Randomized Control Group Pretest-Postest Design with Consecutive Sampling Approach. Jumlah subyek adalah 30 orang yang dibagi menjadi 2 kelompok (15 closed suction system, 15 open suction system). Masing-masing kelompok diberikan oral hygiene tiap 12 jam selama 48 jam. Tiap kelompok diambil sekret dari trakhea sebelum dan sesudah perlakuan, untuk kemudian dilakukan pemeriksaan hitung jumlah dan jenis bakteri. Uji statistik dilakukan menggunakan Wilcoxon dan Mann -Whitney test.

Hasil: Hitung bakteria berbeda bermakna pada kelompok I (p=0,001) dan berbeda bermakna pada kelompok II ( p=0,005). Analisis komparatif selisih skor sebelum dan sesudah perlakuan kedua kelompok berbeda tidak bermakna (p=0,008).

Simpulan: Penggunaan closed suction system pada pasien dengan ventilasi mekanik mengurangi jumlah bakteri post-intervensi secara signifikan, demikian halnya dengan open suction system. Closed suction system tidak lebih baik dalam mengurangi jumlah bakteri pada penelitian ini.
