The concentration of lactic acid in synovial fluid was estimated in 43 specimens from patients with an acute monoarthritis by a simple enzyme method. In 9 patients with 10 episodes of septic arthritis concentrations of synovial fluid lactic acid were significantly higher (mean 10.8 mmol/l) than in 33 patients with nonseptic effusions (mean 3.1 mmol/l). With this method concentrations of synovial fluid lactic acid provide a rapid diagnostic guide in the separation of septic from nonseptic arthritis.
采用一种简单的酶法对43例急性单关节炎患者的滑膜液乳酸浓度进行了测定。在9例发生10次化脓性关节炎的患者中,滑膜液乳酸浓度(平均10.8 mmol/L)显著高于33例非化脓性积液患者(平均3.1 mmol/L)。用这种方法,滑膜液乳酸浓度可为区分化脓性关节炎和非化脓性关节炎提供快速的诊断指导。
