预防术中缝针丢失的新方法探索

Exploration a new method of preventing the lost of suturing-needle during the operation

目的探索预防术中缝针丢失的新方法。方法（1）普通缝针：①对照组：采用盲法，连续行接触放针法、夹持缝针抛掷法、夹持缝针法，操作1200次。②实验组：增加器械托盘的缓冲作用，与对照组做相同的操作1200次。（2）无损伤带线缝合针保管：采用针盒法及改良法实验操作各180次。结果（1）对照组发生弹针率为0．75％；实验组弹针率为O，两组实验比较差异有显著意义（P〈0．01）。（2）对照组失针率为17．22％；实验组失针率为0，两组实验比较差异有显著意义（P〈0．01）。结论对普通缝针增加器械托盘的缓冲作用、对无损伤带线缝合针采用改良法保管，在预防术中缝针丢失的方法中作用明显，且价格低廉，取材方便。

Objective To explore a new method of preventing the suture-needle lost during operation. Methods （1） General suture needle： tangent needles, flight suture and clip suture were manipulated continuously 1200 times in control group; same manipulating was performed as control group and cushioning effect of appliance salver was added in experiment group. （2） Scatheless suture-needle with string safekeeping： Experiments of needle box method and improved method are performed 180 times respectively. Results （1） The shells-pin rate in control group was 0.75%; while that of experimental group was 0%. The difference between the two groups was significant （P〈0.01）. （2） The lost-pin rate in control group was 17.22%, and that of experimental group was 0%. The experimental difference between the two groups was significant （P〈 0.01）. Conclusions The cushioning effect of appliance salver and scatheless suture with string safekeeping will be a significant inexpensive and easy method in preventing the suture lost.
