目的 研究地佐辛复合丙泊酚对腹式子宫切除术牵拉反应的预防作用。方法 选择择期行腹式子宫切除术患者60例(ASA I ~Ⅱ级),随机分成三组。所有患者给予腰麻,麻醉平面调节并固定于T₆后,给予A组患者0.1 mg/kg地佐辛,静脉注射;B组静脉注射0.1 mg/kg地佐辛后丙泊酚持续泵注2~4 mg/(kg·h);C组单次静注丙泊酚1.5 mg/kg后持续泵注2~4mg/(kg·h)。记录麻醉前(T₀)、腰麻平面固定后(T₁)、静注药物后5min(T₂)、切皮(T₃)、牵拉子宫时(T₄)、术毕(T₅)患者的HR、MAP及Ramesay镇静评分;评价肌松效果、牵拉反应、患者舒适度及满意度。结果 三组患者一般情况无差异(P＞0.05);与T₀相比,Ⅲ组T₂及T₅时刻MAP与T₀相比差异有统计学意义(P＜0.05),T₂、 T₃ 、T₄及T₅时刻HR与T₀相比差异有统计学意义(P＜0.05);与T₀相比,Ⅱ组及Ⅲ组Ramesay镇静评分在T₂、 T₃及T₄时刻均升高,差异有统计学意义(P＜0.05);Ⅱ组及Ⅲ组Ramesay镇静评分在T₂、T₃及T₄时刻高于I组,差异有统计学意义(P＜0.05)。牵拉反应评价I组评为优的患者个数明显少于II组及III组,评为良及差的患者个数多于II组及III组,此差异有统计学意义(P＜0.05);II组及III组舒适度及满意度评定为优的患者个数明显多余I组,差异有统计学意义(P＜0.05)。结论 0.1 mg/kg地佐辛复合丙泊酚可以很好预防腹式子宫切除手术中的牵拉反应,提高患者舒适度和满意度。

Objective To observe whether dezocine combined with propofol can prevent intra operative dragging reaction during hysterectomy or not. Methods Sixty patients(ASAⅠ~Ⅱ)which through hysterectomy surgery were randomly arranged to 3 groups. All the patients were under spinal anesthesia, adjusted the anesthesia plane to T6. Group l: dezocine 0.1 mg/kg were intravenous injected, Group ll: dezocine 0.1 mg/kg were intravenous injected and then propofol 2~4 mg/kg/h were intravenous pumped, Group lll: propofol 1.5 mg/kg were intravenous injected and then propofol 2~4 mg/kg/h intravenous were pumped. HR、MAP and Ramesay scale were recorded at the time points of pre-anesthesia(T₀)、pre-injection(T₁)、5 min after injection(T₂)、skin incision(T₃)、dragging uterus(T₄)、after surgery(T₅),the effect of muscle relaxation and the reaction of patients were recorded in the mean time, comfort degree and satisfaction degree of patients were evaluated after surgery. Results There was no significant difference of general condition between the three groups (P>0.05). At the time point of T₂ and T₅, MAP of Group lll patients were significant lower than the base value(P<0.05). At the time point of T₂、T₃、T₄ and T₅, HR of Group lll patients were significant lower then base value(P<0.05). Dragging reaction during the surgery were significant reduced in Group ll and Group lll but not in Group l(P<0.05). Group ll and Group lll patients felt more comfortable and more satisfied than Group l patients(P<0.05). Conclusion 0.1 mg/kg dezocine combined with propofol can prevent intra operative dragging reaction and make patient feel more comfortable during hysterectomy.

目的 探讨拉米夫定治疗对乙肝活动的肺结核病人抗结核治疗中的临床价值。方法 通过回顾性分析159例初治肺结核乙肝表面抗原(HBsAg)阳性、HBV-DNA定量阳性病人,所有病例在抗结核前查肝功能均正常,分为两组,治疗组:在抗结核及护肝治疗过程中,加用拉米夫定抗乙肝病毒治疗;对照组:没用任何抗乙肝病毒药物;分别在抗结核治疗前、治疗2周、4周及8周复查肝功能,对比两组间肝损发生率,及肝损发生时间及严重程度。抗结核治疗4周后复查HBV-DNA定量,对比两组间HBV-DNA定量下降例数。结果 治疗组的肝损发生率仅20.5%,对照组病人抗结核治疗后肝损的发生率为53.1%,两者间差异有统计学意义。治疗组肝损出现时间多为大于4周,而且多数是轻度肝损。治疗组出现肝损中断抗结核治疗的病例数低于对照组。抗乙肝病毒治疗后复查HBV-DNA定量降低例数高于对照组。结论 拉米夫定抗乙肝病毒治疗,能抑制乙肝病毒复制,降低乙肝合并肺结核病人的肝损发生率并减轻肝损严重程度,提高病人对抗结核药物的耐受性。
