Objective
To retrospectively analyze the clinical practicability and value of ultrasound-guided minimally invasive catheterization combined with compound Phellodendron Phellodendri liquid in the treatment of breast abscess during lactation.
Methods
139 patients with lactational breast abscess discharged from our hospital from January 2021 to November 2023 were selected. We divided them into groups according to treatment methods, analyzed whether there were statistical differences in observation indexes among groups and the risk factors affecting breastfeeding rate and treatment satisfaction.
Results
We found that numerical rating scale(NRS) score and incidence of breast fistula in group A were significantly lower than other, the continuous decrease of postoperative drainage in group A was higher than other, there were significant differences among groups (p<0.001). Univariate analysis showed that recovery time, drainage tube placement time, postoperative redness and swelling regression time, scar length, and VAS score of six groups were statistically significant (p<0.001). We found that the overall satisfaction and the rate of continued breastfeeding in group A (96.2%) were higher than other, the differences were statistically significant(p<0.05). Logistic regression analysis revealed that the significant risk factors influencing treatment satisfaction included the time of drainage tube placement, postoperative redness and swelling regression time, treatment group, surgical method, NRS score on the first day after operation, postoperative drainage volume, healing time, scar length, flushing drugs, and VAS score. Postoperative redness and swelling regression time, treatment group, operation method and VAS score are all risk factors that influence the outcome of breastfeeding.
Conclusion
Ultrasound-guided minimally invasive catheterization combined with compound cortex phellodendri fluid in the treatment of breast abscess during lactation can not only reduce the pain caused by dressing change, but also offer numerous advantages, including shorter healing time, beautiful appearance, lower incidence of breast fistula, high satisfaction and high rate of continued breastfeeding.

目的 回顾性分析超声引导下微创置管联合复方黄柏液（compound Phellodendri liquid）治疗哺乳期乳腺脓肿的临床实用性与应用价值。
方法 选取2021年1月至2023年11月于我院出院的139例哺乳期乳腺脓肿患者作为研究对象。按照治疗方案将其分为不同组别，分析各组间观察指标的统计学差异，以及影响母乳喂养率与治疗满意度的危险因素。
结果 本研究发现，A组患者的数字评定量表（numerical rating scale，NRS）评分及乳腺瘘管发生率均显著低于其余组别，A组术后引流液持续减少情况优于其余组别，组间差异均具有统计学意义（p<0.001）。单因素分析显示，6组患者的恢复时间、置管时间、术后红肿消退时间、瘢痕长度及视觉模拟评分法（visual analogue scale，VAS）评分均存在统计学差异（p<0.001）。A组患者的总体满意度及持续母乳喂养率（96.2%）均高于其余组别，差异具有统计学意义（p<0.05）。Logistic回归分析显示，影响治疗满意度的显著危险因素包括置管时间、术后红肿消退时间、治疗组别、手术方式、术后首日NRS评分、术后引流量、愈合时间、瘢痕长度、冲洗药物及VAS评分。术后红肿消退时间、治疗组别、手术方式及VAS评分均为影响母乳喂养结局的危险因素。
结论 超声引导下微创置管联合复方黄柏液治疗哺乳期乳腺脓肿，不仅可减轻换药带来的疼痛，还具备诸多优势：愈合时间更短、外观美观、乳腺瘘管发生率更低、患者满意度高且持续母乳喂养率高。
