[Abstract] Objective: To investigate the application of Dexmedetomidine combined with Propofol and Remifentanil in gynecological endoscopic surgery under BIS monitoring and its effect on anesthesia. Method: From April 2018 to April 2019, 54 patients who underwent gynecological laparoscopic hysterectomy were selected as subjects. They were divided into observation group and control group according to the random number table method, 27 cases in each group. The control group was given Propofol with Remifentanil, the observation group was given Dexmedetomidine combined with Propofol and Remifentanil under BIS monitoring. The postoperative recovery and cognitive function were compared, and the MAP and HR at different time points were compared, the amount of narcotic drugs, sedation and adverse reactions during the operation were compared between the two groups. Result: The response recovery time, breathing recovery time and wake-up time of the observation group were lower than those of the control group (P<0.05). The postoperative MMSE score of the observation group was higher than that of the control group (P<0.05). The MAP and HR at T3, T4, and T5 in the observation group were lower than those in the control group (P<0.05). The amount of Propofol and Remifentanil in the observation group were lower than those in the control group (P<0.05). The sedation in the observation group was better than that in the control group (P<0.05). The incidence of adverse reactions in the observation group was 18.51%, lower than 55.55% in the control group (P<0.05). Conclusion: Under BIS monitoring, Dexmedetomidine combined with Propofol and Remifentanil has a significant anesthetic effect, which can effectively promote the recovery of postoperative cognitive function in patients undergoing gynecologic endoscopic surgery, and is conducive to the smooth completion of surgery and high safety, and has clinical application value.
本研究中,觀察組與對照組在T0、T1時(shí)點(diǎn)的MAP、HR比較,差異均無統(tǒng)計(jì)學(xué)意義(P>0.05),觀察組在T2、T3、T4、T5時(shí)點(diǎn)的MAP及HR均低于對照組(P<0.05),主要是因?yàn)锽IS作為一種新型技術(shù),采用電腦雙頻指數(shù)實(shí)時(shí)、動(dòng)態(tài)地監(jiān)測血流動(dòng)力學(xué)變化,能夠幫助手術(shù)醫(yī)生科學(xué)的把握術(shù)中麻醉深度,提升麻醉效果[15]。右美托咪啶能通過抑制去甲腎上腺素遞質(zhì),終止傳導(dǎo)疼痛信號。并通過抑制交感神經(jīng)元活性,從而有效控制術(shù)中MAP和心率水平,鎮(zhèn)靜鎮(zhèn)痛和抗交感效果顯著[16]。BIS監(jiān)測下右美托咪啶復(fù)合丙泊酚和瑞芬太尼能有效控制婦科腔鏡手術(shù)患者平均動(dòng)脈壓、心率變化,維持血流動(dòng)力學(xué)的穩(wěn)定狀態(tài),有利于手術(shù)成功完成。
本研究中,觀察組術(shù)中丙泊酚與瑞芬太尼用量均低于對照組(P<0.05),鎮(zhèn)靜情況好于對照組(P<0.05),主要是因?yàn)閶D科腹腔鏡下子宮全切除術(shù)時(shí)間較短,需要患者在術(shù)前盡快進(jìn)入理想麻醉狀態(tài),如麻醉深度不夠,術(shù)中出現(xiàn)知曉的概率較高。如麻醉深度過深,術(shù)后蘇醒時(shí)間過長則會影響術(shù)后恢復(fù)質(zhì)量[17]。BIS是監(jiān)測觀察婦科腹腔鏡手術(shù)麻醉用藥的重要手段,通過對術(shù)中監(jiān)測觀察的數(shù)值變化進(jìn)行判斷,在保障術(shù)中不知曉的情況下,合理調(diào)控并有效控制術(shù)中麻醉用藥量。右美托咪定是具有較高的選擇性的新型腎上腺素能受體激動(dòng)劑,作為局部麻醉時(shí)的輔助藥物,可有效減少局部麻醉藥物的用量[18-19],BIS監(jiān)測下右美托咪啶復(fù)合丙泊酚和瑞芬太尼,可顯著降低術(shù)中丙泊酚與瑞芬太尼用量,有利于提升麻醉效果。
本研究中觀察組術(shù)后不良反應(yīng)發(fā)生率18.52%,低于對照組55.56%(P<0.05),主要是因?yàn)楸狙芯恐袐D科腔鏡術(shù)后不良反應(yīng)與術(shù)中鎮(zhèn)靜效果和丙泊酚與瑞芬太尼的用量有關(guān)。BIS通過監(jiān)測術(shù)中麻醉深度,科學(xué)合理地調(diào)整和控制丙泊酚與瑞芬太尼用量,從而降低惡心嘔吐、拔管嗆咳等不良反應(yīng)。右美托咪啶是α2受體激動(dòng)藥,能有效抑制手術(shù)刺激引起的交感神經(jīng)系統(tǒng)興奮,明顯降低術(shù)后寒戰(zhàn)的發(fā)生,鎮(zhèn)靜鎮(zhèn)痛作用顯著且對阿片類藥的呼吸抑制無協(xié)同作用[20],有效減少了術(shù)后躁動(dòng)、呼吸暫停、心跳異常等不良反應(yīng)。BIS監(jiān)測下右美托咪啶復(fù)合丙泊酚和瑞芬太尼能起到良好的協(xié)同鎮(zhèn)痛效應(yīng),降低不良反應(yīng)發(fā)生,有利于術(shù)后恢復(fù)。
綜上所述,BIS監(jiān)測下右美托咪啶復(fù)合丙泊酚和瑞芬太尼麻醉效果顯著,能有效促進(jìn)婦科腔鏡手術(shù)患者術(shù)后認(rèn)知功能的恢復(fù),有利于手術(shù)順利完成且安全性較高,具有臨床推廣應(yīng)用價(jià)值。
