The iron content of split skin grafts from guinea pigs has been studied by flameless atomic absorption spectrophotometry from the time the grafts were cut until the transplants had been in contact with a standardized recipient area for 7 days. The iron content was taken as a measure of the blood content of the grafts. In order to relieve pain, general anaesthesia with ether, local anaesthesia by infiltration and local percutaneous anaesthesia with a solution of ketocaine. A2358, were used. At the time of cutting the grafts the iron content was highest when percutaneous anaesthesia had been used. After a decrease in the iron content in all grafts during the two first postoperative days there was an increasing level from the third day as a sign of revascularization. A stabilization of the values when general and percutaneous anaesthesia had preceded the operation was noted from the fifth postoperative day. The level was highest in the grafts cut after percutaneous anaesthesia.
采用无火焰原子吸收分光光度法，对豚鼠断层皮片从切取时起直至移植到标准化受体部位并接触7天期间的铁含量进行了研究。铁含量被用作衡量皮片血液含量的指标。为缓解疼痛，使用了乙醚全身麻醉、浸润局部麻醉以及用酮卡因溶液A2358进行局部经皮麻醉。在切取皮片时，使用经皮麻醉时铁含量最高。在术后头两天所有皮片的铁含量均下降后，从第三天起含量开始上升，这是血管再形成的迹象。术后第五天注意到，术前采用全身麻醉和经皮麻醉的皮片，其铁含量值趋于稳定。经皮麻醉后切取的皮片铁含量最高。
