Perbandingan Profil Farmakokinetika Bupivakain 0,5% pada Pasien Hamil Normotensi dan Preeklampsia yang Menjalani Sectio Caesarea di RSUP dr. Sardjito Yogyakarta

Helmina Wati, Dita A. D. Sandi

Abstract


Pada kehamilan preeklampsia terjadi penurunan filtrasi glomerulus dan penurunan protein plasma dibandingkan terhadap hamil normotensi. Penelitian ini bertujuan melihat perbedaan profil farmakokinetika dengan model nonkompartemen bupivakain 0,5% antara pasien hamil normotensi dengan pasien hamil preeklampsia yang menjalani Sectio Caesarea (SC). Penelitian dilakukan terhadap 5 pasien hamil normotensi vs hamil preeklampsia yang menjalani SC dengan teknik epidural menggunakan bupivakain 0,5% dosis 75 mg di Gedung Bedah Sentral Terpadu (GBST) RSUP Dr. Sardjito Yogyakarta. Darah diambil sebanyak 3 cc pada menit ke-0;15’;20’;25’;30’;45’;60’;90’ melalui vena dan ditetapkan kadar bupivakain dengan menggunakan metode High Performance Liquid Chromatography (HPLC). Harga profil farmakokinetika bupivakain (AUC (Area Under Curve), AUMC (Area Under Moment Concentration), MRT (Mean Resident Time)) dihitung berdasarkan data kadar bupivakain dalam darah versus waktu dengan model nonkompartemen. Profil farmakokinetika pasien hamil normotensi dan hamil preeklampsia kemudian dianalisis dengan uji statistik untuk melihat ada tidaknya perbedaan. Hasil penelitian menunjukkan AUC(0–~) rata-rata pada pasien hamil normotensi dan pasien hamil preeklampsia secara berturut-turut adalah 109,56± 9,22 μg.mL–1.menit dan 133,780±25,47 μg.mL–1.menit. Nilai AUMC(0–~) rata-rata pada pasien hamil normotensi dan pasien hamil preeklampsia secara berturut-turut sebesar 6.956,41±2.559,99 µg/mL.menit2 dan 11.085,74±5733,94 µg/mL.menit2. Rata‑rata nilai MRT pasien hamil normotensi dan pasien hamil preeklampsia secara berturut-turut sebesar 64,06±25,70 menit dan 110,45±78,30 menit. Hasil uji statistik menunjukkan bahwa nilai AUC(0–~), AUMC(0–~), dan MRT pada obat bupivakain 0,5% antara pasien hamil normal dengan pasien preeklampsia tidak memiliki perbedaan yang signifikan (p>0,05). Kesimpulannya, profil farmakokinetik bupivakain pada pasien hamil normotensi dan preeklampsia tidak memiliki perbedaan yang signifikan.

Comparison of Pharmacokinetics Profiles 0.5% Bupivacaine of Normal Pregnant Patients and Preeclampsia Patients Undergoing Sectio Caesarea at dr. Sardjito Hospital Yogyakarta

Abstract
In preeclampsia pregnancy, there is a decrease in glomerular filtration and plasma protein. This study was conducted on 5 patients with normotensive pregnancy and sectio caesarea with preeclampsia pregnancy used of bupivakain 0,5% dose of 75 mg. Blood was collected as much as 3 cc at minute 0; 15’;20’;25’;30’;45’;60’;90’, through a vein and set the levels of bupivacaine by using High Performance Liquid Chromatography (HPLC). The value of bupivacaine pharmacokinetic profile (AUC (Area Under the Curve), AUMC (Area Under Concentration Moment), MRT (Mean Time Resident)) were calculated based on the levels of bupivacaine in the blood versus the time with noncompartement models, and then were analyzed with statistical test. The result showed that the value of AUC(0–~); value of AUMC(0–~); value of MRT on average for patients with normal pregnancy and preeclampsia pregnant patients respectively were 109.56±9.22 μg.mL-1.minute and 133.78 ± 25.47 μg.mL-1.minute; 6,956.41 ± 2,559.99 µg/mL.minute2 and 11,085.74±5733,94 µg/mL.minute2; 64.06±25.70 minutes and 110.45± 78.30 minutes. Statistical analysis results showed that the value of AUC(0–~), AUMC(0–~), and MRT at bupivacaine had no significant difference (p>0.05).
