RESUMO
Objective To investigate the effect of ultrasonic scalpel combined with hemostatic gauze to reduce the postoperative axillary wound drainage in breast cancer patients after surgery .Methods 243 cases of breast cancer patients admitted from Mar .2011 to May.2014 were selected as the research object , and they were divided into four groups according to the envelope method:group A(67 cases), group B(59 cases), group C(56 cases), and group D(61 cases).The four groups were given different surgical hemostatic methods: ultrasonic scalpel combined with hemostatic gauze in group A , ultrasonic scalpel without hemostatic gauze in group B , elec-tric knife and hemostatic gauze in group C , and electric knife in group D .The operation time , intraoperative blood loss , postoperative drainage , and drainage tube indwelling time were observed and compared between the four groups.Results The operation time and intraoperative blood loss had no significant difference between group A and group B(P>0.05), yet there was significant difference in postoperative drainage and drainage tube indwelling days ( P0.05), yet there was significant difference in the intraoperative blood loss , postoperative drainage and drainage tube indwelling days (P<0.05).There was significant difference when the same indicator of group A and group B compared with group C or group D ( P<0.05 ) .Conclusion Ultrasonic scalpel combined with hemostatic gauze used in breast cancer surgery can effectively reduce the axillary wound exudation , and shorten the drainage time .
RESUMO
Objective To compare the influence of two different managements of relief incision (exposed relaxation therapy or absorbable hemostatic gauze) in infants' palatoplasty. Methods A total of 118 infants with cleft palate between 5- to 8-month-old for the study were randomly divided into two groups: group A was exposed therapy group, and in group B both sides of relief incision were placed absorbable hemostatic gauze. The wound bleeding, body temperature, diet and incidence of fistula were observed and analyzed after operation. Results There was no significant difference between the two groups in postoperative temperature, diet and wound healing (P>0. 05). The postoperative wound bleeding was statistically significant differences between the two groups (P<0. 05). Conclusions Either exposed therapy or placed absorbable hemostatic gauze in relief incision, has minimal systemic and local reactions in the postoperative infant. The advantages of exposed treatment are economic and simple, and less irritant to the wound.
