【摘要】：目的:探索右美托咪定復(fù)合瑞芬太尼在中期妊娠患者引產(chǎn)術(shù)鎮(zhèn)靜的最小有效劑量,旨在為右美托咪定在中期妊娠引產(chǎn)術(shù)中的應(yīng)用提供合理依據(jù),以確保產(chǎn)婦在引產(chǎn)過程中的安全性。方法:選擇年齡18-45歲,ASA I或II級的產(chǎn)婦參加本實驗。當(dāng)產(chǎn)婦進(jìn)入產(chǎn)房后,常規(guī)監(jiān)測心率、無創(chuàng)血壓、脈搏血氧飽和度、呼吸頻率、BIS值。對所有產(chǎn)婦給予面罩持續(xù)吸氧(氧流量2-3L/min),開放上肢靜脈通道。給予瑞芬太尼負(fù)荷劑量0.5μg/kg,持續(xù)泵注劑量0.05μg/kg/min,同時泵注右美托咪定,初始劑量0.2μg/kg/h,給藥后26分鐘評估產(chǎn)婦的鎮(zhèn)靜深度,通過改良序貫法來確定右美托咪定的劑量,若上一例產(chǎn)婦意識抑制陽性,則下一例產(chǎn)婦藥物劑量減少0.05μg/kg/h,反之增加0.05μg/kg/h,直至研究結(jié)果出現(xiàn)7個意識抑制陰性轉(zhuǎn)陽性的轉(zhuǎn)折點(diǎn),研究結(jié)束。意識抑制陽性定義為:睫毛反應(yīng)消失,Ramsay評分4級,BIS值≤70。結(jié)果:共有26例產(chǎn)婦參加研究,右美托咪定用于中期妊娠引產(chǎn)患者出現(xiàn)意識抑的ED50、ED95及其95%CI分別為0.39μg/kg/h(0.32~0.61μg/kg/h)、0.62μg/kg/h(0.48~1.95μg/kg/h)。結(jié)論:右美托咪定復(fù)合瑞芬太尼用于中期妊娠引產(chǎn)術(shù)患者鎮(zhèn)靜的半數(shù)有效劑量為0.39μg/kg/h。
[Abstract]:Objective: to explore the minimum effective dose of dexmetomidine combined with remifentanil in the sedation of induced labor in the second trimester of pregnancy, so as to provide a reasonable basis for the application of dexmetomidine in the induction of labor in the second trimester. To ensure the safety of pregnant women during induction of labor. Methods: women aged 18-45 years with ASA I or II were enrolled in this study. Heart rate, noninvasive blood pressure, pulse oxygen saturation, respiratory frequency and BIS value were routinely monitored when the parturient entered the labor room. All parturients were given continuous oxygen inhalation (oxygen flow rate 2-3 L / min), opening of upper limb venous passage. The loading dose of remifentanil was 0.5 渭 g / kg, the continuous dose was 0.05 渭 g / kg / min, and the initial dose was 0.2 渭 g / kg / h. 26 minutes after administration, the depth of sedation was evaluated, and the dose of dexmetomidine was determined by the modified sequential method. If the last case was positive for consciousness inhibition, the next case had a decrease in drug dose of 0.05 渭 g / kg / h, whereas an increase of 0.05 渭 g / kg / h, until the results of the study showed 7 turning points of negative to positive of consciousness inhibition. Consciousness inhibition positive is defined as: eyelash response disappeared and Ramsay score grade 4 and BIS 鈮，
