目的探讨乳腺癌改良根治术后不同负压引流效果。方法对148例乳腺癌改良根治手术后患者进行随机分组,应用三种不同负压引流,观察三组引流量及带管时间并进行对照分析和比较。结果高负压引流组平均总引流量多于中负压引流组,平均总带管时间长于中负压组。中负压组平均总引流量少于低负压组,平均总带管时间短于低负压组,差别有统计学意义。高压引流组平均总带管时间稍短于低负压组,平均总引流量稍多于低负压引流组。结论中等负压引流可以减少引流量,缩短带管时间。
Objective To investigate the effect of different negative pressure drainage after modified radical mastectomy for breast cancer. Methods A total of 148 patients with modified radical mastectomy for breast cancer were randomly divided into three groups. Three different types of negative pressure drainage were used to observe the drainage volume, the time of tube insertion, and the comparative analysis and comparison. Results The average total drainage volume of high negative pressure drainage group was more than that of negative suction drainage group, and the average total length of lead time was longer than that of negative pressure group. In the negative pressure group, the average total drainage was less than that in the low negative pressure group, and the average total length of lap tube was shorter than that in the low negative pressure group. The difference was statistically significant. The average total catheterization time in the high pressure drainage group was slightly shorter than that in the low negative pressure group, and the average total drainage volume was slightly more than that in the low negative pressure drainage group. Conclusions Medium negative pressure drainage can reduce drainage volume and shorten the time of tube insertion.
