左、右手打结训练对腹腔镜下打结操作的影响

Effect of left and right hand knotting training on laparoscopic knotting operation

目的:比较左、右手打结训练对腹腔镜下打结操作的影响。方法:选择2017年11月—2018年10月不同医学院校实习生32人,分为左手打结组(左手组)16人和右手打结组(右手组)16人,经临床三个阶段的培训后,比较两组培训前后腹腔镜打结时间、打结质量及打结方法得分。结果:培训前,左手组打结时间为590.50 s,少于右手组的590.50 s(P <0.05),打结得分为2.25分,高于右手组的2.00分,但组间差异无统计学意义(P> 0.05)。培训后,两组打结时间、打结得分差异均无统计学意义(P> 0.05),但均优于培训前。结论:左手打结训练对于掌握腹腔镜打结有一定的临床实践价值和指导意义。

Objective: To compare the effects of left and right hand knotting training on laparoscopic knotting operation. Methods: From November 2017 to October 1818, 32 interns from different medical colleges were selected, including 16 left-handed knotting group (left-handed group) and 16 right-handed knotting group (right-handed group). After three stages of clinical training, laparoscopic knotting time, knotting quality and knotting method scores before and after training were compared between the two groups. Results: Before the training, the knotting time of the left-hand group was (590.50) s, which was less than that of the right-hand group (590.50) s (P < 0.05). The knotting score was 2.25 points of the left-hand group, which was higher than the 2.00 points of the right-hand group, but the difference between the groups was not statistically significant (P > 0.05). After the training, there was no statistical significance in the knotting time and the score in the right and left hand group (P > 0.05), but they were better than those before training. Conclusion: Left hand knotting training has certain clinical value and guiding significance for mastering laparoscopic knotting.
