摘　　要：目的在实验室研究的基础上,找出既能满足临床需要又能避免垂直移动注射泵注出率短时间改变不良影响的泵体安全移动固定方法。方法对胸心外科60例心脏手术后回到ICU的患者持续使用微量注射泵注入硝普钠,将微量注射泵每次移动(15±5)cm,分2次移动达(30±5)cm的固定高度,移动前和每次移动后持续监测记录患者10min内的心率、平均动脉压变化并进行比较。结果移动前与移动2次后患者的平均动脉压波动范围均在82.5～84mmHg之间,差异不足1.5mmHg;平均心率均在90.5～92.5次/min间波动,差异在2次/min内,波动范围很小,对患者的动脉压和心率没有造成明显影响。结论分次垂直移动≤(15±5)cm的高度而到达临床所需固定高度,是对垂直移动注射泵后短时间注出率改变影响最小的安全移动高度。Objective To find,on the basis of laboratory research,a safe vertical movement and fixation meth- od of micro-injection pump in order to meet the clinical needs and avoid the effect of temporary infusion rate change during movement on the patient＇ s vital signs. Methods Sixty cardiac surgery patients who continued postoperative in- fusion of sodium nitroprusside by micro-injection pump were sent back to the ICU in the department of Cardiothoracic Surgery were observed,micro-injection pump was moved two times, each time of （15 -＋ 5）cm, until to achieve the height of （30 ＋ 5）cm at the bedside. The continuous monitoring of the heart rate and mean arterial blood pressures be- fore movement and within 10 rain after movement were recorded and compared. Results The patient＇ s mean arterial blood pressure fluctuated in the range of 82. 5 - 84mmHg before and after two movements. The differences were less than 1.5mmHg. The average heart rate fluctuated between 90. 5 - 92. 5 beats/min; the difference was 2 times/rain,the fluctuation range was very small. No significant effects on the patient＇ s arterial pressure and heart rate were found. Con- clusion The safe staging vertical movement height of micro-injection pump with minimal temporary infusion rate change is ~〈 （ 15 ＋ 5 ） cm. The purpose of the movements is to achieve a height of clinical requirement in fixed pump and did not cause the change of patient＇ s vital signs. This is a secure methods of moving and fixing micro-injection pump.
