【摘要】：目的評價丙泊酚復合瑞芬太尼用于經陰道取卵術麻醉的臨床效果,根據(jù)給藥時間、劑量和藥代動力學模型,用計算機模擬藥物濃度,建立并分析藥效學模型及其特點。方法靜脈麻醉下行經陰道取卵術患者42例,ASAⅠ或Ⅱ級,隨機分為兩組,分別靜脈注射瑞芬太尼1.5μg/kg+丙泊酚1.5mg/kg(PR15組,n=24)或瑞芬太尼1.0μg/kg+丙泊酚1.0 mg/kg(PR10組,n=18)。根據(jù)患者體動反應和自訴疼痛情況,酌情追加瑞芬太尼0.5μg/kg和/或丙泊酚0.5 mg/kg。麻醉質量評價主要指標包括睫毛反射消失時間、定向力恢復時間、低氧發(fā)生率(SpO_292%)及其他不良反應�；谀M濃度、非線性混合效應模型、采用NONMEM軟件建立藥效學模型。結果PR15組患者定向力恢復時間明顯慢于PR10組[(4.9±1.3)min vs(3.6±1.2)min,P0.05];但兩組睫毛反射消失時間[(58±14)s vs(64±13)s]、低氧(12.5%vs 16.7%)和咳嗽(16.7%vs11.1%)發(fā)生率差異無統(tǒng)計學意義。50%患者有效鎮(zhèn)靜的丙泊酚濃度和有效鎮(zhèn)痛的瑞芬太尼濃度(EC_(50))分別是1.71μg/ml、2.57ng/ml;95%患者有效鎮(zhèn)靜的丙泊酚濃度和有效鎮(zhèn)痛的瑞芬太尼濃度(EC_(95))分別為4.30μg/ml、4.57ng/ml。丙泊酚1.0 mg/kg產生的峰效應位濃度低于EC_(50),而1.5mg/kg產生的峰效應位則高于EC_(50);但瑞芬太尼1.0、1.5μg/kg產生的峰效應位濃度均高于EC_(50),后者接近EC_(95)。結論基于患者恢復時間,經陰道取卵術麻醉時瑞芬太尼1.0μg/kg復合丙泊酚1.0mg/kg較為合適。
[Abstract]:Objective to evaluate the clinical effect of propofol combined with remifentanil in anaesthesia of transvaginal oocyte extraction. According to the model of administration time, dose and pharmacokinetics, the pharmacodynamics model and its characteristics were established and analyzed by computer simulation of the concentration of propofol and remifentanil. Methods Forty-two patients with transvaginal oocyte extraction were randomly divided into two groups: intravenous remifentanil 1.5 渭 g/kg propofol 1.5mg/kg(PR15 group (n = 24) or remifentanil 1.0 渭 g/kg propofol group (n = 20) or remifentanil 1.0 渭 g/kg propofol group (n = 18). Remifentanil 0.5 渭 g/kg and / or propofol 0.5 mg / kg were added according to the patient's body movement and private pain. The main indexes of anaesthesia quality evaluation included the disappearance time of mascara reflex, the recovery time of directional force, the incidence of hypoxia, SpO292) and other adverse reactions. Based on the model of simulated concentration and nonlinear mixing effect, the pharmacodynamics model was established by NONMEM software. Results the recovery time of orientation in PR15 group was significantly slower than that in PR10 group [4.9 鹵1.3)min vs(3.6 鹵1.2 min P0.05], but there was no significant difference in the incidence of effective propofol concentration and effective propofol concentration between the two groups [58 鹵14s vs(64 鹵13s, 12.5% vs 16.7 vs 16.7i] and cough group (16.7vs 11.1g). The effective sedative concentration of propofol and the effective analgesic concentration of remifentanil in 95% patients were 4.30 渭 g / ml / ml and 4.57 ng / ml / ml, respectively. The peak effect site concentration of propofol 1.0 mg/kg was lower than that of mg/kg, while the peak effect level of 1.5mg/kg was higher than that of ECS, but the peak effect level of remifentanil 1.0 渭 g/kg was higher than that of ECS. Conclusion based on the recovery time, remifentanil 1.0 渭 g/kg combined with propofol 1.0mg/kg is more suitable for vaginal oocyte extraction anesthesia.
