Surgical site infection risk factors
Of 16,513 patients in a study, 1.20% required at least one further operation to treat a surgical site infection (SSI). Wound leak (odds ratio [OR]: 27.41), dexamethasone use (OR: 3.55), instrumentation (OR: 2.74) and operative time >180 minutes (OR: 1.85) were statistically significant risk factors for reoperation 1).
It is still discussed if the dual use increases the risk of surgical site infections (SSI).Increase of extent of tumor resection using intraoperative magnetic resonance imaging (iMRI) is evident. SSI rate is within the normal range of neurosurgical procedures. A dual-use iMRI suite is a safe concept 2).
Local subcutaneous fat thickness is a better indicator for predicting incision infection compared with BMI. In diabetic patients undergoing lumbar surgery, actively controlling blood glucose fluctuations, restoring normal diet early after surgery, and optimizing surgical procedures to reduce trauma and operative time can effectively reduce the risk of infection after posterior lumbar surgery 3).
Despite the general consensus on the use of single-dose antimicrobial prophylaxis (AMP) in instrumented spine surgery, evidence supporting this approach is not robust. Analysis of individual categories of data suggests that 72 h prophylaxis was the most important factor for minimizing the risk of wound infection in a study group 4).
Cassir et al. identified the following independent risk factors for SSI postcranial surgery: intensive care unit (ICU) length of stay ≥7 days (odds ratio [OR] = 6.1; 95% confidence interval [CI], 1.7-21.7), duration of drainage ≥3 days (OR = 3.3; 95% CI, 1.1-11), and cerebrospinal fluid leakage (OR = 5.6; 95% CI, 1.1-30).
For SSIs postspinal surgery, they identified the following: ICU length of stay ≥7 days (OR = 7.2; 95% CI, 1.6-32.1), coinfection (OR = 9.9; 95% CI, 2.2-43.4), and duration of drainage ≥3 days (OR = 5.7; 95% CI, 1.5-22) 5).
