摘　　要：目的通过基于遥感技术的静脉穿刺角度监测仪,测量不同熟练度人群在进行静脉穿刺时的进针角度,探究其熟练度、进针角度和穿刺成功率之间的关系。方法招募无静脉穿刺经验的本科二年级学生和有3年以上临床工作经验的护士各30人,在手臂橡胶穿刺模型上进行穿刺,记录2组穿刺时的预估角度,读取监测仪给出的穿刺实际角度,记录其穿刺成功结果,进行分析。结果护士组穿刺成功率为96.7%(58/60),学生组的穿刺成功率为51.7%(31/60),差异有统计学意义(χ2值为29.4,P<0.05);护士组角度预估平均差异为(5.2 ± 1.9)°,学生组角度预估平均差异为(8.9 ± 2.6)°,差异有统计学意义(Z值为-7.10,P<0.05);最适合初学者的静脉穿刺角度范围是(31.6 ± 6.4)°。结论穿刺的成功率和穿刺的角度存在着相关关系,对于初学者来说,最适宜角度范围在(31.6 ± 6.4)°;操作者对角度的预估值偏大普遍存在;基于遥感技术的角度监测仪使得静脉穿刺的精准研究成为可能。Objective To explore the relationship between their proficiency,needle penetration angle and the success rate of puncture by using a self-developed venipuncture angle monitor based on remote sensing technology,and measured the needle penetration angle of people with different venipuncture proficiency levels.Methods A total of 30 sophomore medical school undergraduates without venipuncture experience and 30 nurses with more than 3 years of clinical experience each were recruited.Volunteers performed punctures on a rubber puncture model of the arm.The result of each puncture,the volunteer′s estimated insertion angle,and the actual insertion angle measured by the monitor were recorded and analyzed.Results The puncture success rate of the nurse group was 96.7%(58/60),and the puncture success rate of the student group was 51.7%(31/60).The puncture success rate of the nurse group was higher than that of the student group(χ2 value was 29.4,P<0.05);The estimated difference of the average angle of the nurse group was(5.2±1.9)°,and the estimated difference of the average angle of the student group was(8.9±2.6)°.The estimated difference of the nurse group was less than the student group(Z value was-7.10,P<0.05);the most suitable venipuncture angle range for beginners was(31.6±6.4)°.Conclusions There is a correlation between the success rate of venipuncture and the puncture angle,and optimum puncture angle for beginners in the controlled model was(31.6±6.4)°.At both skill levels,operator estimates of the puncture angle were commonly larger than the actual angle.The angle monitor based on remote sensing technology makes the precise study of venipuncture possible.
