Objective To evaluate the hemostasis effect of balloon urinary catheter after vacuum-assisted breast biopsy (VABB).Methods From May.2016 to May.2017,270 patients undergoing VABB were randomized into study group (135 cases) and control group (135cases).Patients in the study group received VABB postoperative indwelling catheter balloon hemostasis,while patients in the control group received VABB postoperative conventional thoracic pressure bandage to stop bleeding.Postoperative bleeding and hematoma were recorded and compared between the two groups.Results The rates of postoperative bleeding and hematoma in the study group were significantly lower than that in the control group (6.7％ vs 16.3％,P＜0.05;8.9％ vs 24.4％,P＜0.05).Among patients with lesions ≤ 1.5 cm,the rates of postoperative bleeding and hematoma were 1.6％ and 4.7％ in the study group,and 6.5％ and 8.1％ in the control group.There was no significant difference between the two group (P＞0.05).Among patients with lesions ＞1.5 cm,the rates of postoperative bleeding and hematoma in the study group were significantly lower than those in the control group (11.3％ vs 24.7％,P＜0.05;12.7％ vs 32.9％,P＜0.05).Conclusion Hemostasis with balloon urinary catheter is a safe and effective method for postoperative bleeding and hematoma control after VABB.

Objective To study the effect of extended nursing on puerperal melancholia incidence.Methods Two hundred perpetrates received interventions of extended nursing after delivery,including education about puerperal state,turning on hot line and creation of QQ group,follow-ups and supporting from family members.Result The incidence rate of puerperal melancholia since performance of extended nursing was significantly lower than what is after its performance(P<0.01).Conclusions The extended nursing can help perpetrates to receive nursing knowledge,alleviate their anxiety,strengthen the confidence to take care of baby.As the result,it can reduce the incidence of puerperal melancholia.
