摘要
目的 探讨一种新的静脉输液拔针后的按压方法。方法 380例需进行静脉输液的患者随机分2组，实验组190例：大面积按压法，示指、中指和无名指3指并排横向。将针眼上、下1-3cm全都压住，按压的力量，以指尖按压变苍白又没变苍白的力量正好，按压时间为3-5min。对照组190例：小面积按压，只按压针眼，用拇指指腹横向按压，力量为指尖按压变苍白，时间同实验组。结果 实验组出血、皮下淤血、血管闭塞（完全、不完全）等并发症的发生率均明显少于对照组（P〈0．05），差异具有统计学意义。结论 此方法确实有效，使患者的血管得到保护，给再次静脉穿刺带来方便。
Objective To study a new pressing method of withdrawal needles after intravenous transfusion. Method 380 patients were randomly divided into two groups： the experimental group （n= 190） and the control group （n=190）. In the experimental group, the pinpoint was pressed with strength that fingertip just became pale for 3-5 minutes at the range of 1-3 cm around it using digitus indicis.digitus medius with digitus annularis. In the control group, just pressed the pinpoint using thumb pulp with strength that fingertip became pale, the lasting time was the same as that of the expermental group. Resalts The complication of the expermental group, such as hemorrhage, sub-congestion, vascular occlusion and so on,is notably less than that of the control group （P〈0.05）,there is significant difference between two groups. Conclusions The pressing method of the experimental group, is indeed effective, it protects not only the blood vessel of patients, hut also provides the convenience for secondary intravenous transfusion.
