目的:观察缩宫素不同静注速度对剖宫产产妇血压与心率的影响。方法:ASAⅠ~Ⅱ级剖宫产产妇80例随机分为两组,每组40例。A组缩宫素静注速度4ml·min~(-1),B组为2ml·min~(-1)。比较两组静注缩宫素前(T_0)、静注后1min(T_1)、2min(T_2)、3min(T_3)、4 min(T_4)、5min(T_5)、6min(T_6)、10min(T_7)的平均动脉压(MAP);静注缩宫素前(T_0)、静注后30s(T_1)、60s(T_2)、90s(T_3)、120s(T_4)、150s(T_5)、300s(T_6)、600s(T_7)的HR、宫缩及药品不良反应。结果:A组产妇T_1~T_66个时间点MAP明显低于B组(P<0.05);T_1~T_7个时间点HR明显较B组快(P<0.05)。结论:剖宫产产妇以2ml·min~(-1)静注缩宫素3u,血压、心率较平稳。
Objective: To observe the effects of oxytocin at different IVF rates on blood pressure and heart rate in cesarean section. Methods: 80 ASA Ⅰ ~ Ⅱ cesarean section women were randomly divided into two groups, 40 cases in each group. A group of oxytocin intravenous injection speed 4ml · min ~ (-1), B group 2ml · min ~ (-1). (T_0), 1min (T_1), 2min (T_2), 3min (T_3), 4min (T_4), 5min (T_5), 6min (T_6), 10min (T_0), 30s (T_1), 60s (T_2), 90s (T_3), 120s (T_4), 150s (T_5) and 300s ), 600s (T_7) of HR, contractions and adverse drug reactions. Results: The MAP of T_1 ~ T_66 in group A was significantly lower than that in group B (P <0.05). The HR of T_1 ~ T_7 was significantly faster than that in group B (P <0.05). Conclusion: Cesarean section with 2ml · min ~ (-1) intravenous oxytocin 3u, blood pressure, heart rate more stable.
