WOUND INFECTION AFTER SCOLIOSIS SURGERY:AN ANALYSIS OF 15 CASES

OBJECTIVE: To discuss the causes and treatments of wound infections after scoliosis surgery. METHODS: Nine hundred and twenty-four caes of scoliosis were reviewed, and the clinical data of 15 cases of postoperative infection were analysed retrospectively. RESULTS: All 15 cases underwent spinal posterior fusion with autologous bone graft using instrumentations. Seven were diagnosed as early infection, and 8 were delayed infection. Radical debridement was performed in all 15 cases. The duration of antibiotics administration was 10 to 34 days with continuous closed irrigation for 2 to approximately 4 weeks and primary closure for the wounds. All patients were followed up for an average of 3.5 years (2 to 7.5 years) with good outcomes and no recurrence. CONCLUSION: Wound infection following surgical correction of scoliosis primarily results from intraoperative seeding, although host-related and operation-related factors may contribute to its development. Once the infections are diagnosed, good results can be achieved by prompt surgical debridement, irrigation and reasonably administered antibiotics. Removal of hardware may be necessary in deep infections.

Risk factors and strategy for surgical incision infection in department of abdominal surgery

Objective To study the risk factors of surgical wound infection among the patients in department of abodominal surgery. Methods The factors on surgical wound infection were investigated by retrospective study. The diagnosis standard was based on Diagnosis Standard of Hospital Infection published by Ministry of Health.

Clinical and microbiological features of community-acquired and nosocomial bloodstream infections in the surgical department of a tertiary-care hospital in Beijing

Background Bloodstream infections （BSls） remain a major cause of morbidity and mortality in patients undergoing surgery. This study aimed at elucidating the clinical characteristics of community-acquired BSIs （CABs） and nosocomial BSIs （nBSIs） in patients admitted to the surgical wards of a teaching hospital in Beijing, China. Methods This cross-sectional study compared 191 episodes of BSIs in 4074 patients admitted to the surgical wards between January 2008 and December 2011. Cases of BSIs were classified as CABs or nBSIs, and the characteristics, relevant treatments, and outcomes of CABs and nBSIs were compared. Results Of the 191 BSIs, 52 （27.2%） and 139 （72.8%）were CABs and nBSIs, respectively. Escherichia coli, coagulasenegative staphylococci, and Klebsiella spp, were the most frequently isolated microorganisms. There were significant differences between CABs and nBSIs with respect to the use of hormonal drugs, ventilation, acute physiology and chronic health evaluation （APACHE） Ⅱand American Society of Anesthesiologists scores, and prevalence of cancer （P 〈0.05）. Empirical antibacterial therapy did not decrease the crude mortality, but multivariate analysis showed that high APACHE Ⅱwas independently associated with a risk of mortality （odds ratio =0.97, 95% confidence interval： 0.93-1.02 for APACHE Ⅱ）. Conclusions We found significant differences in the clinical characteristics of surgical patients with CABs and nBSIs. The outcome of patients seems to be related to hiah APACHE Ⅱ scores.
