Abstract
Increasing heat loss and reducing heat production are the main causes for anesthetic hypothermia. Patients with low body temperature are found associated with unwanted and potentially life-threatening complications. These consequences include decreased resistance to surgical wound infections, and higher chance of developing surgical site infection.
Various passive insulators and active warming systems are available for use intraoperatively. Forced-aie warmer, a hot air blowing warming system is proven to be able to prevent anesthetic hypothermia and suggested to be introduced during anesthesia by human medical guidline. In arthroplasty and neurosurgery, stricktly surgical environment sterile level is required. Concerns are raised about forced-air warmer might bring skin bacteria flora into sterile surgical site and cause surgical site infection.
The purpose of this study is to investigate the relationships between two different active warming devices and the surgical field contaminations rates.
A total of 57 surgery cases were included in the study. Type of warming device, species, surgical wound category, operation room, numbers of scrub-in personnel, surgical drape type, surgical drape secure method, and surgeon who performed the surgery were recorded. Chi-Square test was used to test the differences between surgical field contamination rate on each category with the statistical significance level set at 5% (p = 0.05).
According to the study, using force-air warming device was not associated with elevating surgical site contamination rate. But there were significant differences in different surgeons and their surgical site contamination rate. Revealing that personnel factor might contribute to surgical site contamination more than environmental factors.
