<![CDATA[Blokade peribulbar dapat memfasilitasi operasi vitrektomi dengan terciptanya akinesia yang baik. Tujuan penelitian ini meneliti mula kerja dan lama kerja levobupivakain untuk blokade peribulbar pada operasi vitrektomi. Penelitian observasional dilakukan pada 64 pasien di kamar operasi lantai 3 di Pusat Mata Nasional Rumah Sakit Mata Cicendo Bandung selama bulan Maret−April 2014. Pengambilan sampel dilakukan dengan metode simple random sampling. Penilaian keberhasilan blokade peribulbar menggunakan sistem Ocular Anasthetic Scoring System (OASS). Pada penelitian ini didapatkan mula kerja rata-rata 23,6±3,7 menit, tercepat 16 menit dan paling lambat 30 menit serta lama kerja rata-rata 5,34±0,5 jam, paling pendek 4,5 jam dan paling panjang 7 jam. Simpulan penelitian ini adalah levobupivakain sebagai anestetik lokal dengan mula kerja dan lama kerja yang cukup baik digunakan pada operasi vitrektomi dengan teknik blokade peribulbar di Pusat Mata Nasional Rumah Sakit Mata Cicendo Bandung.Kata kunci: Blokade peribulbar, levobupivakain, mula kerja, lama kerja obat, Ocular Anasthetic Scoring System (OASS)Onset and Duration of Levobuvacaine in Peribulbar Block for Vitrectomy in National Eye Centre of Eye Hospital Cicendo BandungAbstractPeribulbar block can facilitate good akinesia for vitrectomy. The aim of this study was to observes the onset and duration of levobupivacaine in peribulbar block for vitrectomy.
