Objective To evaluate the effect of wound protector on preventing incisional wound infection following class Ⅲ-Ⅳincision abdominal operation.Methods Patients who had undergone class Ⅲ-Ⅳincision abdominal opera-tion from January 2013 to December 2014 were divided into trial group and control group according to whether they had used wound protector ,incidence of postoperative incisional wound infection between two groups were com-pared.Results A total of 310 patients were monitored,150 cases in trial group,and 160 cases in control group. Incidence of incisional wound infection in trial group was significantly lower than control group (4.00% [n=6]vs 11 .88%[n=19],χ2 =6.48,P <0.05).The average operation time and length of hospital stay in trial group were both shorter than control group ([42.10±3.30]min vs [58.30±4.10]min,P <0.05;[7.00±2.20]d vs [10.00 ±3.50]d ,P <0.05),score of pain assessment of incision in trial group was lower than control group([2.00 ± 1 .70]vs [3.00±1 .80],P <0.05).Conclusion Wound protector can effectively reduce the incidence of incisional wound infection following class Ⅲ-Ⅳincision abdominal operation.

Objective To investigate the management status of loaner surgical instruments,and evaluate the effect of plan-do-check-act cycle (PDCA)quality control on loaner surgical instrument management.Methods From July 2011 to June 2012,8 965 pieces of loaner surgical instruments before adopting PDCA quality control management was as control group;from July 2012 to June 2013,8 564 pieces of loaner surgical instruments adopting PDCA quality control was as ob-servation group.The defects of loaner surgical instruments during application process and effect of PDCA quality control on loaner surgical instrument management were analyzed.Results There were many problems in checking-tracking,cleaning quality and company personnel of loaner surgical instruments.The qualified rate of observation group was higher than that of control group(99.36% vs 96.27%)(χ2 =194.74,P <0.01).The main causes for unqualification of observation group were unqualified cleaning (n=21 ,38.18%)and incomplete function of instruments(n=8,14.55%);while the main causes for unqualification of control group were the loss of instruments(n=81,24.25%),lack of monitor and record (n=71, 21.26%),unqualified cleaning(n=55,16.47%)and the soaking of package(n=54,16.17%).Conclusion PDCA quality control is an effective method for loaner surgical instruments management,it is helpful for building long-term effective quali-ty control system for loaner surgical instruments,and make loaner surgical instrument management more scientific,system-atic,and standard.
