Complications due to inaccurate pneumatic tourniquet pressure-gauge readings have been well described. However, no standard protocol for regular testing of the tourniquet apparatus, especially at the pressures used in clinical practice, appears to have been developed. We therefore developed a protocol for testing the Kidde pneumatic tourniquet apparatus and used this protocol to test 13 apparatuses in regular use at several hospitals in the Western Cape. We found that 8 of the apparatuses checked were inaccurate by as much as 350 mmHg, 8 had defective valves and 1 was considered to be too dangerous for further clinical use. This random survey shows that the majority of pneumatic tourniquet apparatuses in clinical use may be inaccurate and that more frequent testing and appropriate maintenance are indicated.
因气动止血带压力计读数不准确而导致的并发症已有详尽描述。然而，似乎尚未制定对止血带设备进行定期检测的标准方案，尤其是针对临床实践中所使用的压力。因此，我们制定了一项检测基迪（Kidde）气动止血带设备的方案，并使用该方案对西开普省多家医院经常使用的13台设备进行了检测。我们发现，所检查的设备中有8台误差高达350毫米汞柱，8台阀门有缺陷，1台被认为对进一步临床使用过于危险。这项随机调查表明，临床使用的大多数气动止血带设备可能不准确，需要更频繁地进行检测并进行适当维护。
