<![CDATA[Salah satu efek samping pascaoperasi dengan anestesi umum adalah mual muntah. Obat 5-HT3 reseptor antagonis telah terbukti efektif mencegah terjadinya mual dan muntah pascaoperasi. Ondansetron merupakan 5-HT3 reseptor antagonis yang sering dipakai, namun memiliki efek samping nyeri kepala. Tropisetron merupakani obat alternatif untuk mencegah mual muntah pascaoperasi. Tujuan penelitian adalah membandingkan efektifitas pemberian tropisetron 5 mg dengan ondansetron 8 mg untuk mengurangi efek mual dan muntah pascaoperasi ginekologis per laparatomi. Uji klinik acak tersamar ganda dilakukan pada 66 pasien di bagi menjadi dua kelompok perlakuan, kelompok tropisetron dan kelompok ondansetron. Data hasil penelitian diuji secara statistik dengan uji t dan uji chi-kuadrat. dari data penelitian diperoleh hasil bahwa skor mual pada kelompok tropisetron berbeda bermakna dibanding kelompok ondansetron sebesar dengan p<0,05. Keluhan mual pada kelompok ondansetron yaitu sebanyak 21 subjek (63,6%) sedangkan pada kelompok tropisentron sebanyak 10 subjek (30,3%) berbeda bermakna dengan p<0,05. Tidak ada perbedaan bermakna pada kedua kelompok pada keluhan muntah dengan 2 subjek (6,1%) yang mengalami muntah. Simpulan penelitian ini adalah pemberian tropisetron 5 mg lebih efektif dibandingkan dengan ondansetron 8 mg untuk mengurangi efek mual dan muntah pascaoperasi ginekologis perlaparatomi.Kata kunci: Mual muntah, ondansetron, skor mual, tropisetron.
Post operative nausea and vomitus (PONV) is one of side effect caused by general anesthesia. 5- HT3 antagonist receptor is effectively proven in preventing PONV. Ondansetron is a common antagonist 5- HT3 receptor widely used with side effect especially complaints of headache. Tropistron can be used as an alternative to prevent PONV. The aim of this study is to compare the effectiveness of 5 mg tropisetron to 8 mg ondansetron in reducing PONV. Double blind randomized control trial was delivered to 66 patients divided into 2 treatment groups, tropisetron and ondansetron. The result of the study was statistically tested with t test and chi square test. The study shows the score of nausea in tropisetron group was less than ondansetron group with p<0,05. Nausea was complained in 21 subject of ondansetron group (63,6%), while in tropisetron group was complained in 10 subject (30,3%) with p<0,05. No significance difference was found in both group with 2 subject ( 6,1%) complaining vomiting. The conclusion of this study is tropisetron 5 mg is more effective than ondansetron 8 mg in reducing PONV
Key words: nausea score, nausea and vomiting, ondansetron, tropisetron
