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.
目的 测试SurgiSafe®（一种用于在手术过程中检测手术用织物的射频电子设备）与人工清点相比的性能。方法 将带有射频标签的手术海绵随机分布放置在接受剖腹手术的猪的腹腔中。对标签进行人工清点，并使用SurgiSafe®进行清点。分析两种方法的阳性和阴性预测值、敏感性、特异性以及清点所需时间。结果 通过对35个手术周期的分析，SurgiSafe®立即识别出所有海绵，其特异性、敏感性、阳性和阴性预测值均为100%。人工清点的敏感性为99.72%，特异性为99.90%，虽无统计学意义。结论 SurgiSafe®被证明是一种在体内实时识别手术海绵的有效设备；将其用作人工清点的辅助手段对提高患者安全性非常有帮助。
