对５８例经受手术创伤的小儿血清锌与血清铜进行了定量分析，结果如下：①经受手术创伤小儿血清锌减少，术后第１天减少极显著（Ｐ＜０．０１）；术后第３天下降明显（Ｐ＜０．０５）；术后第７天恢复至术前水平。②经受大手术创伤小儿的血清铜含量仅于术后第１天有显著减少（Ｐ＜０．０１），而经小手术创伤者则无明显变化。
Quantitative analysis of serum zinc and serum copper in 58 children undergoing surgical trauma was performed. The results were as follows: (1) Serum Zinc decreased in children with traumatic trauma and decreased significantly on the first postoperative day (P <0.01) The days were significantly lower (P <0.05), and returned to the preoperative level on the 7th day after operation. ② Serum copper levels in pediatric trauma patients decreased significantly only on the first postoperative day (P <0.01), but no significant changes were found in the minor trauma patients.
