The use of various types of filters in anaesthesia and intensive care seems ubiquitous, yet authentication of the practice is scarce and controversies abound. This review examines evidence for the practice of using filters with blood and blood product transfusion (standard blood filter, microfilter, leucocyte depletion filter), infusion of fluids, breathing systems, epidural catheters, and at less common sites such as with Entonox inhalation in non-intubated patients, forced air convection warmers, and air-conditioning systems. For most filters, the literature failed to support routine usage, despite this seemingly being popular and innocuous. The controversies, as well as guidelines if available, for each type of filter, are discussed. The review aims to rationalize the place of various filters in the anaesthesia and intensive care environment.
各种类型的过滤器在麻醉和重症监护中的使用似乎无处不在，但这种做法的认证却很少，争议也很多。本综述研究了在血液和血液制品输注（标准血液过滤器、微过滤器、白细胞去除过滤器）、液体输注、呼吸系统、硬膜外导管以及较少见部位（如非插管患者吸入恩多诺克斯、强制空气对流保暖器和空调系统）使用过滤器的证据。对于大多数过滤器，尽管其使用看似普遍且无害，但文献并未支持常规使用。本文讨论了每种过滤器的争议以及可用的指南。本综述旨在使各种过滤器在麻醉和重症监护环境中的应用更加合理。
