应考虑K+Na+的含量青霉素类多以钠钾盐形式供药用,钾盐每100万u含K+159.1 mg,钠盐每100万u含Na+38.3 mg。目前临床上对重症患者静滴一次用量达1 000万u以上,所以不能不考虑K+Na+对心、肝、肾功能和电解质平衡的影响。青霉素的静滴时间青霉素类作用于细菌细胞分裂后期形成的细胞壁,细菌细胞分裂后期给药可收到最好的治疗效果。若长时间静滴,不仅故果不大,还易水解导致药效降低。故建议除青霉素钾盐外,如静滴,应将一次量溶于100 ml输 Consideration should be given to the content of K + Na + Penicillins are mostly used in the form of sodium and potassium salts, with K + 159.1 mg per million u of potassium and Na + 38.3 mg per million u of sodium. At present, the dosage of intravenous infusion for critically ill patients reaches more than 10 million u, so we can not but consider the influence of K + Na + on heart, liver, kidney function and electrolyte balance. Penicillin infusion of penicillin role in bacterial cell division late formation of the cell wall, bacterial cell division late delivery can receive the best therapeutic effect. If prolonged intravenous infusion, not only the fruit is not large, but also easy to hydrolyze lead to lower efficacy. It is recommended in addition to penicillin potassium, such as intravenous infusion, should be dissolved in a volume of 100 ml lose
