Objective To explore the status and influencing factors of surgical site infection (SSI)following lapa-roscopic surgery in patients in department of general surgery,so as to take effective measures to reduce SSI. Methods Active monitoring method was used to survey SSI among 401 patients undergoing laparoscopic surgery from January 1 ,2013 to December 31 ,2013,univariate analysis and multivariate analysis on risk factors for SSI were conducted.Results Of 401 investigated patients,12 (2.99%)developed SSI.Univariate analysis showed that risk factors for SSI in patients with laparoscopic surgery were elderly patients,emergency operation,infected wound,gastrointestinal tract operation,and grade Ⅳof ASA score (all P <0.05 ).Multivariate logistic regression analysis revealed that elderly patients (OR,5.02[95%CI ,1 .38 -30.25]),emergency operation (OR,4.37 [95%CI ,1 .96-28.55]),infected wound (OR,7.27[95%CI ,2.54-25.05]),and gastrointestinal tract operation (OR, 8.13 [95%CI ,1 .38 - 18.33 ])were high risk factors for SSI following laparoscopic surgery (all P < 0.05 ). Conclusion Thereare multiple factors influencing SSI after laparoscopic surgery,diversified prevention and control measures can effectively reduce the incidence of postoperative SSI.

Objective: To observe the effect of traditional Chinese medicine foment package in spontaneous heat position pad to prevent lower extremity deep venous thrombosis (LEDVT) during general anesthesia. Methods: From April 2018 to April 2019, 160 cases during general anesthesia were selected and divided into the control group(common hot pad for leg and knee) and the experimental group(self-control position pad for leg and knee) with 80 cases each by the random number table method. The coagulation function and deep venous thrombosis were observed and compared between the two groups. Results: There was no significant difference in coagulation function between the two groups on the 1 day before operation (P > 0.05). The level of D-dimer, prothrombin time, fibrinogen, platelet count on the 5 days after operation was (1.28 ± 0.39) g/L, (11.75 ± 0.81) s, (4.37 ± 0.71) g/L, (203.39 ± 32.12)×10⁹/L in the control group, and (0.96 ± 0.17) g/L, (11.45 ± 0.67) s, (3.93 ± 0.65) g/L, (186.10 ± 34.69)×10⁹/L in the experimental group, and there was significant difference between the two groups (t=2.553-6.728, P <0.01). The incidence of LEDVT on the 5 day after operation was 4%(3/80) in the experimental group and 18% (77/80) in the control group, and there was significant difference between the two groups (χ²=5.005, P<0.05). Conclusions The spontaneous fever knee pad with traditional Chinese medicine foment package can improve the blood coagulation function of general anesthesia patients, and the incidence of LEDVT is lower than that of the control group 5 days after operation.
