. New insufflators have been developed to manage leaks emanating from the working cavity during laparoscopic surgery. Little data have been published to show the performance of these insufflators. This study evaluates the performance of 2 modern continuous pressure insufflators in various leak conditions. . Performance of a new continuous pressure insufflator, EVA15 (Palliare, Galway, Ireland), was compared with that of a continuous pressure insufflator, Airseal intelligent Flow System (iFS) (CONMED, Utica, NY), and a traditional intermittent pressure insufflator, Endoflator 40 (KARL STORZ, Tuttlingen, Germany). Six different leak scenarios were created in a swine model to create different dynamic leak profiles of between 5 and 15 L/min. Pressure deviation from setting was measured for each insufflator tested. The following were calculated: (a) mean absolute difference of measured insufflation pressure vs. the insufflator pressure setting for the 50 second measurement period (MAD) and (b) standard deviation of the absolute differences (SD). . The average mean absolute pressure difference between the EVA15 and Airseal is .27 mmHg. However, the average mean absolute pressure difference between the EVA15 and Endoflator 40 is 2.62 mmHg. . Continuous pressure insufflators provide superior pressure delivery performance in leak situations when compared against a traditional intermittent pressure insufflator. No clinically significant performance difference was observed when comparing the EVA15 and Airseal iFS insufflators in the tested leak situations.
. 已经开发出了新型的注气设备来处理腹腔镜手术中工作腔产生的泄漏。目前发表的数据很少，无法展示这些注气设备的性能。本研究评估了两种新型连续压力注气设备在各种泄漏情况下的性能。. 比较了一种新型连续压力注气设备 EVA15（爱尔兰戈尔韦的 Palliare）与连续压力注气设备 Airseal intelligent Flow System（iFS）（纽约尤蒂卡的 CONMED）和传统的间歇压力注气设备 Endoflator 40（德国图特林根的 KARL STORZ）的性能。在猪模型中创建了六种不同的泄漏情况，以创建不同的动态泄漏曲线，泄漏率在 5 到 15 升/分钟之间。为每个测试的注气设备测量了压力偏离设定值的情况。计算了以下两个参数：（a）50 秒测量期内测量的注气压力与注气设备压力设定值之间的平均绝对差值（MAD），和（b）绝对差值的标准差（SD）。. EVA15 和 Airseal 的平均绝对压力差值为.27 毫米汞柱。然而，EVA15 和 Endoflator 40 之间的平均绝对压力差值为 2.62 毫米汞柱。. 与传统的间歇压力注气设备相比，连续压力注气设备在泄漏情况下提供了更优越的压力输送性能。在测试的泄漏情况下，比较 EVA15 和 Airseal iFS 注气设备，没有观察到临床显著的性能差异。
