目的探讨催产素不同给药方法对剖宫产患者血流动力学的影响。方法收集即将接受剖宫产手术的产妇100例,将其平均分为Ⅰ组和Ⅱ组,两组产妇均予以5IU缩宫素加入5ml的生理盐中静脉给药,Ⅰ组产妇的给药时间控制在5min以上,Ⅱ组患者的给药时间控制在1min以内,比较分析两组产妇的血流动力学变化。结果Ⅱ组产妇T1、T2、T3期的HR、MAP、SVR平均水平明显高于T0期,差异具有统计学意义(P<0.05),SV、TFC平均水平与T0期比较,差异无统计学意义(P>0.05),Ⅰ组产妇各时期的HR、MAP、SV、SVR、TFC平均水平比较,差异均无统计学意义(P>0.05),两组之间比较,Ⅱ组产妇T1、T2期的HR、MAP、SVR平均水平均明显高于Ⅰ组产妇,其差异具有统计学意义(P<0.05)。结论催产素能够对产妇血流动力学的稳定性造成影响,适当的延长给药时间可以促进产妇血流动力的稳定。
Objective To investigate the effects of different oxytocin administration methods on hemodynamics in patients with cesarean section. Methods 100 cases of maternal women who were about to undergo cesarean section were collected and divided into two groups. Group Ⅰ and group Ⅱ were equally divided into two groups. The mothers in both groups were treated with 5IU oxytocin and 5ml physiological saline intravenously. Control in more than 5min, Ⅱ group of patients administered within 1min control, comparative analysis of the two groups of maternal hemodynamic changes. Results The average HR, MAP and SVR of T1, T2 and T3 in group Ⅱ were significantly higher than those in stage T0 (P <0.05), and there was no significant difference between the average level of SV and TFC (P> 0.05). The average HR, MAP, SV, SVR and TFC in each group were no significant difference between the two groups (P> 0.05) The mean HR, MAP and SVR were significantly higher than those in group Ⅰ, the difference was statistically significant (P <0.05). Conclusions Oxytocin can affect the hemodynamic stability of the maternal, and proper prolongation of the dosage can promote the stability of the hemodynamics of the maternal.
