Abstract

ANTONIO, Adriana Marco  and  VIEIRA, Carlos Andre Pereira. Evaluation of radiofrequency electronic system in intraoperative monitoring of surgical textiles. Einstein (São Paulo) [online]. 2018, vol.16, n.1, eAO3997.  Epub May 07, 2018. ISSN 2317-6385.  https://doi.org/10.1590/s1679-45082018ao3997.

Objective

To test performance of SurgiSafe®, a radiofrequency electronic device to detect surgical textiles during operations as compared to manual counting.

Methods

Surgical sponges with radiofrequency TAGs were placed in the abdominal cavity of a pig submitted to laparotomy, in randomly distributed sites. The TAGs were counted manually and also using SurgiSafe®. Positive and negative predictive values, sensitivity, specificity and time required for counting were analyzed for both methods.

Results

Through the analysis of 35 surgical cycles, SurgiSafe® immediately identified all sponges, with specificity, sensitivity, positive and negative predictive values of 100%. Although not statistically significant, the manual count had sensitivity of 99.72% and specificity of 99.90%.

Conclusion

SurgiSafe® proved to be an effective device to identify surgical sponges in vivo, in real time; and its use as an adjuvant to manual counting is very helpful to increase patient's safety.
