小剂量去氧肾上腺素静脉泵注在高龄患者髋关节置换手术中的应用

目的观察持续静脉泵注小剂量去氧肾上腺素对高龄髋关节置换手术患者的循环稳定作用。方法36例行髋关节置换手术的高龄患者。术中常规监测血压、心率、ECG和SpO2,记录出血量、输液量、输血量等指标,术后24小时复查肾功能。结果所有患者手术经过顺利,生命体征稳定,术中血压降幅不超过20％,未见严重围手术期并发症。结论高龄患者围手术期持续静脉泵注去氧肾上腺素有助于降低血压下降程度,维持心脑等重要器官的血供,减少心脑血管不良事件的发生,提高麻醉的安全性。

Intravenous Infusion of Low Dose Phenylephrine in Elderly Patients Undergoing Hip Replacement

Objective To observe the effect of intravenous infusion of low dose phenylephrine in aged patients undergoing hip replacement. Methods The blood pressure, heart rate, ECG and SpO2 were monitored during surgery in total 36 elderly patients, and the amount of bleeding, amount of infusion, and blood transfusion were recorded; the renal function was examinated 24 hours postoperatively. Results All of the operations were finished with stable vital signs; the blood pressure during surgery was more than 80% of the baseline, with no serious complications. Conclusions Intravenous infusion of low dose phenylephrine in elderly patients undergoing hip replacement can stabilize blood pressure, maintain blood supply of heart, brain and other vital organs, reduce cardiovascular adverse events, and improve the safety of anesthesia.
