肝癌射频消融术的麻醉方法临床观察

The Clinical Investigation of Aanesthesia of Rradiofrenquency Aablation

目的研究单纯丙泊酚镇静和气管插管复合麻醉下行RFA术中的血流动力学变化及不良反应的发生情况。方法 A组患者在单纯丙泊酚诱导及维持下行RFA,而B组患者在气管插管复合麻醉下行RFA。记录两组患者诱导前、术中及术毕的SBP、DBP、MAP、HR、SpO2,观察术中的不良反应如舌根后坠、低氧血症、体动等情况。结果与B组相比。A组患者术中的血压及心率比术前明显升高(P<0.05),SpO2有所下降;A组不良反应发生率明显高于B组(P<0.05),有显著统计学差异。结论单纯丙泊酚静脉镇静行RFA术中麻醉较浅,血流动力学不稳定,不良反应发生率显著增高,麻醉和手术风险加大,而气管插管复合麻醉则安全、可靠。

Objective To investigate the hemodynamics and adverse reactions during RFA in simple-propofol-sedation or general anesthesia combined with endotracheal intubation.Methods Patients in group A were simply Induced and maintained ith propofol,while Group B were anesthetized in Endotracheal intubation.Record the SBP,DBP,MAP and SpO2 in preoperat iveintroperative and postoperative period,respectively.Observe the adverse affairs during operation such as lingual root fall behind,hypoxemia,body movement.Result Introperative BP and HR in Group were significantly higher than preoperatively（P〈0.05）,and SpO2 decreased obviously（P〈0.05）.Group A of adverse events incidence was significantly higher than the Group B（P〈0.05）.Conclusion Simple-propofol-sedation couldn＇t provide enough anesthetic depth for RFA.Adverse reactions especially unstable hemodynamics occur more frequently.It increases the Risk of anesthesia and operation.Endotracheal intubation can present safe and reliable anesthesia for RFA.
