Campos impregnados com iodo em cirurgia da coluna: impacto na infecção de sítio cirúrgico

Objective: To evaluate the impact of iodine-impregnated incision drapes (IIIDs) to prevent surgical site infection (SSI) in the spine. Method: Retrospective cohort study comparing SSI outcome in patients in which IIIDs were and were not used, from 2015 to 2019. Results: The overall frequency of SSI was 16.7%, with SSI rate among patients using and not using IIIDs of 40% and 60%, respectively; p = 0.728; 95% confidence interval (95%CI) 0.19– 3.11. Normothermia was the only independent protective factor for SSI (p = 0.043). The treatment of infectious complications resulted in hospital costs increase of 83.6% each day of care. Patients who were treated with IIIDs stayed 10 days less (± 4.9) in hospital. Conclusions: The results suggest that the use of IIIDs was not associated with a lower risk of SSI. These data can be useful for surgical planning and patient safety.
