万可松预注对血钾的影响

Effect of priming vecuronium on serum potassium

４０例病人随机分为两组，一组用琥珀胆碱２ｍｇ．ｋｇ－１作常规诱导（对照组），另一组用万可松２０ｕｇ．ｋｇ－１预注后诱导，两组分别于诱导前、诱导后２ｍｉｎ、诱导后２０ｍｉｎ抽血测定血钾的变化。结果：对照组诱导后２ｍｉｎ血钾明显升高，另一组无明显改变。

Forty patients were randomly divided into two groups One group received conventional induction with 2mg kg -1 of succinylcholine as a control, The other group were pretreated with Vecuronium 20ug kg -1 The serum potassium levels of the forty patients were measured before induction and 2, 20min after intubation In control group, The serum potassium were sigificantly increased ( P <0 05) at 2min after intubation, but the other group did not change markedly The serum potassum of two groups returned to basic levels 20min after intubation respectively The results showed that priming Vecuronium can prevent further increase of the serum polassium
