Pengaruh Indeks Massa Tubuh terhadap Kejadian Mual Muntah Post Operasi

Calculation of Body Mass Index (BMI) needs to be known before surgery in order to minimize the cause of nausea and vomiting after surgery due to side effects of anesthesia. Post-Operative Nausea and Vomiting (PONV) can cause medical complications, psychological effects, and hamper the overall therapy process so that it reduces the recovery rate of postoperative patients and affects the burden of care costs during treatment. The research purpose was to examine the correlation between Body Mass Index and the incidence of post-operative nausea and vomiting. The research used cross-sectional method. The samples were 30 postoperative respondents with inclusion and exclusion criteria. The data collection used the questionnaire of nausea and vomiting from Rhodes Index Nausea, Vomiting and Retching (Rhodes INVR). The results of univariate analysis showed as many as 56.7% of respondents experienced mild PONV and 73.3% of respondents had normal range of BMI. The bivariate analysis used an unpaired comparative test more than two groups. The test results obtained p value 0.201 > 0.05; thus, there is no significant effects of Body Mass Index on the incidence of post-operative nausea and vomiting.Perhitungan Indeks Massa Tubuh (IMT) perlu diketahui sebelum dilakukan tindakan operasi agar meminimalisir penyebab terjadinya mual muntah setelah operasi akibat dari efek samping anastesi. Post Operative Nausea and Vomiting (PONV) dapat menimbulkan komplikasi medik, efek psikologis, dan menghambat proses terapi secara keseluruhan sehingga menurunkan tingkat kesembuhan pasien post operasi serta mempengaruhi beban biaya perawatan selama dirawat. Adapun tujuan dari penelitian ini untuk mengetahui pengaruh indeks masa tubuh terhadap kejadian mual muntah pasca operasi. Penelitian ini mengunakan metode cross-sectional. Sampel berjumlah 30 responden post operatif yang termasuk pada kriteria inklusi dan ekslusi. Pengumpulan data menggunakan kuesioner mual muntah dari Rhodes Index Nausea, Vomiting dan Retching (Rhodes Invr). Hasil analisis univariat sebanyak 56,7% responden mengalami mual muntah ringan dan sebanyak 73,3% responden memiliki indeks massa tubuh dalam rentang normal. Analisis bivariat menggunakan uji komparatif tidak berpasangan lebih dari 2 kelompok. Hasil uji menunjukkan nilai p = 0,201 > 0,05, maka tidak ada pengaruh signifikan indeks massa tubuh pada kejadian mual muntah post operasi
