Sixteen adults undergoing cardiac surgery were studied with respect to postoperative levels of zinc in plasma and urinary excretion of zinc. The preoperative plasma concentrations of zinc were normal. On the first postoperative day the mean for the series had fallen from 15 to 7.2 mumol/l. A gradual rise followed, and on the fifth day all patients had plasma zinc above the lower limit of normal range. The urinary excretion of zinc was significantly increased on the first, second and fifth days after surgery. The mean total of zinc in the urine during five days was 67 mumol. The short-term fall in plasma zinc level had no discernible effect on wound healing. It was therefore apparently harmless and did not indicate a need for zinc supplementation.
对16名接受心脏手术的成年人的血浆锌术后水平和锌的尿排泄情况进行了研究。术前血浆锌浓度正常。术后第一天,该系列的平均值从15微摩尔/升降至7.2微摩尔/升。随后逐渐上升,到第五天所有患者的血浆锌均高于正常范围下限。术后第一天、第二天和第五天锌的尿排泄显著增加。五天内尿液中锌的平均总量为67微摩尔。血浆锌水平的短期下降对伤口愈合没有明显影响。因此,这显然无害,也不表明需要补充锌。
