目的减少复杂先天性心脏病术后患者更换盐酸肾上腺素、异丙肾上腺素等特殊药物时生命体征的波动以及输液管气泡的发生。方法将100例使用特殊药物患者随机分为对照组和观察组各50例。对照组采用常规更换特殊药法,观察组使用同步双管换药的方法。结果观察组心率、动脉血压波动阳性发生率及输液管气泡发生率显著低于对照组(P<0.05,P<0.01)。结论复杂先天性心脏病术后患者更换特殊药物时采用同步双管接药法,可明显减少心率、动脉血压波动以及输液管气泡发生。
Objective To reduce the fluctuation of vital signs and the occurrence of infusion tube bubbles in patients with complicated congenital heart disease after the replacement of special drugs such as epinephrine hydrochloride and isoprenaline. Methods 100 cases of patients using special drugs were randomly divided into control group and observation group of 50 cases. Control group using conventional replacement of special drug law, the observation group using synchronous double tube dressing method. Results The incidence of heart rate fluctuation and arterial blood pressure fluctuation in the observation group were significantly lower than those in the control group (P <0.05, P <0.01). Conclusions In patients with complicated congenital heart disease, synchronous double-pipe method can significantly reduce heart rate, arterial blood pressure fluctuation and infusion tube bubble when replacing special drugs.
