Narcotrend监测下七氟醚和丙泊酚全麻苏醒期特征比较

目的观察和比较Narcotrend麻醉深度监测下丙泊酚与七氟醚全麻苏醒期的特征,以及苏醒时的Narcotrend指数(NTI)是否一致。方法选择60例择期行经鼻蝶垂体瘤切除术患者,随机分为四组,每组15例。丙泊酚深麻醉组(PD组)和七氟醚深麻醉组(SD组)术中维持NTI在46~37,丙泊酚浅麻醉组(PL组)和七氟醚浅麻醉组(SL组)术中维持NTI在56~47。记录苏醒时的NTI、苏醒时间、拨管迟滞时间。结果苏醒时PD组NTI为84.2±2.7,PL组84.9±2.5,明显低于SD组88.6±3.4与SL组89.9±3.3(P0.05),拨管迟滞时间SD组(9.4±4.6)min,明显长于SL组(4.7±2.4)min(P0.05),PD组与PL组差异无统计学意义。SD组苏醒时间较其余三组明显延长(P0.05),SL组、PD组和PL组苏醒时间差异无统计学意义。结论丙泊酚与七氟醚全麻患者苏醒时的NTI并不一致。

Comparison of emergence characteristics between sevoflurane and propofol anesthesia under the guide of Narcotrend

Objective To compare the emergence characteristics between propofol total intrave-nous anesthesia (TIVA)and sevoflurane induction and maintenance anesthesia (VIMA)under the guidance of Narcotrend,and to see if the recovery of consciousness after different anesthesia regimen will be of identical Narcotrend index (NTI).Methods Sixty ASA Ⅰ or Ⅱ patients undergoing elective transsphenoid pituitary tumor resection were randomized to receive deep anaesthesia (D)or light anaesthsia (L)with propofol (P)/remifentail (group PD and group PL)or sevoflurane (S)/remifentanil (group SD and group SL).During surgery,anesthesia was maintained at a depth of NTI at 46-37 or 56-47 for deep or light anesthesia respectively.After surgery,group comparisons of the NTI at extubation,recovery time,and the time interval between NTI 80 and extubation (Tdelay )were performed by analysis of variance.Results The NTI at consciousness was significantly lower in group PD (84.2±2.7)and PL(84.9±2.5)compared with group SD (88.6 ±3.4)and group SL (89.9 ± 3.3)(P < 0.05 ).The Tdelay was significantly longer in group SD (9.4 ± 4.6 )min compared with group SL (4.7±2.4)min (P <0.05),but there was no difference between group PD and group PL. Compared with other groups,the recovery time was longer in group SD (P <0.05).Conclusion The results indicate that the NTI values at recovery of consciousness are not identical between patients re-ceived proposfol or sevoflurane anesthesia.
