Abstract

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.
