摘　　要：目的 评价TL_300tensymeter系统（TL_300）所测的连续无创血压（NIBP）在全身麻醉中的有效性及安全性。方法 选择全身麻醉下行择期仰卧位手术的成年患者20例,ASAⅠ~Ⅲ级。麻醉诱导后无菌操作下左侧桡动脉穿刺置入动脉导管进行连续有创血压（IBP）监测,右侧手臂连接TL_300进行NIBP监测,稳定5min后,同时测量IBP和NIBP,间隔3min分别记录IBP监测及相应时点NIBP监测的收缩压、舒张压和平均压。术后监测与两种血压监测相关的并发症如肢体缺血、坏死、感觉异常。结果 NIBP监测与IBP监测所测收缩压、舒张压和平均压差值分别为（-0.086±9.59）、（3.203±7.11）、（2.60±6.76）mmHg,两种血压监测方法的收缩压、舒张压和平均压的决定系数分别为0.711、0.565和0.729,P值均小于0.001。所有患者均未发生肢体缺血、坏死、感觉异常。结论 与IBP监测相比,NIBP监测在全身麻醉成年手术患者中,可提供连续、无创、准确、安全的血压监测。Objective To investigate the accuracy, precision and safety of continuous non- invasive blood pres- sure（NIBP） monitoring delivered by TL_300 tensymeter system. Methods Twenty ASA classification of I - m adult patients undergoing elective surgeries in a supine position under general anesthesia were included in the study. A catheter was placed into the left radial artery under local anesthesia before induction, with the TL_300 tensymeter system connected to the right arm. Continuous invasive blood pressure （IBP） monitoring was derived from the invasive artery catheter while the NIBP was from TL_300 tensymeter system. Systolic, diastolic and mean arterial pressure were recorded every 3 mi- nutes simultaneously for both IBP and NIBP from 5 min after monitoring to the end of surgery. Complications associated with both pressure monitors including limb ischemia, necrosis and paresthesia were reem＇ded postoperatively. Results Data showed that difference between IBP and NIBP was （ - 0. 086±9.59 ） mmHg, （ 3. 203± 7. 11 ） mmHg and （ 2. 60±6. 76 ） mmHg for systolic arterial pressure, diastolic arterial pressure, mean arterial pressure, respectively. The correlation coefficient between two methods was 0. 843,0. 752 and 0. 854 for systolic, diastolic and mean pressure, respectively. No limb ischemia, necrosis and paresthesia were observed in any patient. Conclusion TL_300 tensymeter system provides continuous, real -time, non -invasive and reliable arterial pressure measurements which is comparable to IBP, and can be safely used in adult patients under general anesthesia during elective surgery.
