One hundred and seventy-four consecutive patients with symptoms of derangement of the knee were examined with an arthroscope under local anaesthesia using a continuous pressure-irrigation system. A 0.2 per cent prilocaine-saline solution was used as irrigation fluid. In the first 19 patients the serum level of prilocaine was monitored for six hours after the start of irrigation. Eighteen of the 174 patients had a transcutaneous partial meniscectomy at the same time as the examination. All the patients tolerated the examination well. The distension of the knee produced by the pressure-irrigation system provided a high degree of diagnostic accuracy. The serum levels of prilocaine were low throughout the monitoring period reaching a mean peak value of 0.28 micrograms per millilitre after one hour. There were no adverse side-effects. This technique provides a safe and efficient method to meet the increasing demands of arthroscopic procedures of the knee.
174例连续的膝关节紊乱症状患者在局部麻醉下使用连续压力冲洗系统进行关节镜检查。使用0.2%的丙胺卡因盐溶液作为冲洗液。在最初的19例患者中，冲洗开始后6小时监测丙胺卡因的血清水平。174例患者中有18例在检查的同时进行了经皮部分半月板切除术。所有患者对检查耐受性良好。压力冲洗系统产生的膝关节扩张提供了高度的诊断准确性。在整个监测期间，丙胺卡因的血清水平较低，1小时后平均峰值为每毫升0.28微克。没有不良副作用。该技术提供了一种安全有效的方法，以满足膝关节关节镜手术日益增长的需求。
