摘要
目的探讨丙泊酚复合小剂量地佐辛在无痛人工流产中的应用。方法选择2012年1—12月在河北省中医院行无痛人工流产术的患者90例,完全随机分为3组,各30例。A组:单纯给予丙泊酚2mg/kg缓慢静脉滴注。B组:缓慢注入芬太尼0.05mg,10min后给予丙泊酚2mg/kg缓慢静脉滴注。C组:缓慢注入地佐辛2.5mg,10min后给予丙泊酚2mg/kg缓慢静脉滴注。患者意识消失,刺激无反应时开始手术,术中出现体动,追加丙泊酚0.5mg/kg。观察麻醉诱导前(T0)、意识消失时(T1)、刮宫时(T2)、术毕时(T3)、唤醒时(T4)各组血压、心率和脉搏血氧饱和度。记录各组丙泊酚的诱导量和总用量,诱导时间、唤醒时间及呼吸抑制和恶心呕吐的情况。结果T1、T3、T4时B、C组平均动脉压和心率均明显低于A组[T2时平均动脉压:(78±12)、(78±12)mmHg(1mmHg=0.133kPa)比(88±11)mmHg,心率:(72±11)、(74±10)次/min比(86±12)次/min;T,时平均动脉压:(80±13)、(80±12)mmHg比(86±12)mmHg,心率:(72±12)、(72±11)次/min比(84±11)次/min;T4时平均动脉压:(80±12)、(81±12)mmHg比(87±12)mmHg,心率:(71±13)、(72±12)次/min比(84±11)次/min,均P〈0.05]。A、B、C,组患者丙泊酚诱导时间分别为(59±8)、(41±7)、(41±6)S;唤醒时间分别为(6±1)、(7±1)、(7±1)min;丙泊酚总用量分别为(160±24)、(107±12)、(97±12)mg。B、C组的丙泊酚诱导时间和丙泊酚总量均分别低于A组,差异有统计学意义(P〈0.05)。B、C组唤醒时间比A组长,但差异无统计学意义(P〉0.05)。A、B、C,组患者发生呼吸抑制分别为4例(13.3%)、10例(33.3%)、2例(6.7%);发生恶心呕吐分别为l例(3.3%)、2例(6.7%)、2例(6.7%)。A、C组呼吸抑制发生率低于B组,差异有统计学意义(P〈0.05);3组恶心呕吐发生率差异无统计学意义(P〉0.05)。结论术前10min给予地佐辛2.5nag超前镇痛用于无痛人工流产术时,与芬太尼0.05mg有相似的镇痛效果,且呼吸抑制明显小于芬太尼。
Objective To study the effect of propofol combined with small doses of dezocine in painless a- bortion. Methods Ninety patients underwent painless induced abortion were randomly divided into three groups. Group A were given dezocine. Group B were given fentanyl and dezocine. Group C were given dezocine and Dezocine. The operation started when the patients had no consciousness and response under stimulation. If there was the body movement, 0.5 mg/kg propofol was added. The blood pressure, heart rate and blood oxygen saturation in each group during the operation were observed. Induction quantity and total dosage of propoful, as well as the induction time, time of wake up, respiratoly depression, nausea and vomiting were recorded. Meanwhile, postopera- tive visit on patient satisfaction was also observed. Results T2 , T3 , T4 in group B and group C mean arterial pres- sure and heart rate were significantly lower than those in group A [ T2 mean arterial pressure: (78 ± 12), (78 _± 12) mmHg (1 mmHg = 0. 133 kPa) vs (88_±11) mmHg; heart rate: (72 ~11), (74 ±10) times/rain vs (86 ± 12) times / rain; T3 mean arterial pressure: (80 ± 13), (80 ± 12) mmHg vs (86 -± 12) mmHg, heart rate: (72 ± 12), (72 ± 11 ) times/rain vs (84 ± 11 ) times/rain; T4 mean arterial pressure: (80 ± 12) , (81 -± 12) mmHg vs (87 e 12) mmHg; heart rate: (71 ± 13), (72 ±/2) times/ufin vs (84 ± 11 ) times/rain, all P〈 0.05]. Propofi)l induction time in group A, group B and group was (59 ±8), (41 ±7), (41 ±6)s, respectively; wake-up time was (6±1), (7±1), (7 ±1) rain; total propotol was (160±24), (107 ±12), (97 ± 12) rag. Propofol induction time and the total amotmt of propofol in group B and group C were significantly lower than those in group A. Conclusion 2.5 mg of dezocine by vein injection 10 minutes before surgery in painless induced 'abortion has the similar analgesic effect compared with 0.05 mg fentanyl application, and even has a significantly smaller respiratory depression.
