The effects of PHT,CT,Calcium and phospho- rus during the anesthesia and operative stress / 中华麻醉学杂志

ABSTRACT

The changes of parathyroid hormone (PTH),calcitonin(CT)of three different anesthesia methods were observed perioperatively in 38 patients who were divided into two age groups (22 ~ 50 and 51 ~ 60). Postoperative serum Ca, P levels decreased as compared with preoperative values,espe.cially in the old. age groups with no statistic significance. These results indicate that during anesthesia and operative stress the CDS is inhibited and the regulation of the autonomic nervous system is affected, with obscure the relationship between parathyroid hormone, calcitonin and Ca, P with the alteration of Ca,P metabolism. Serum Ca may increase to the baseline by supplement of calcium gluconate during and after operation, but the operation after 4 ~ 5 days, serum Ca may also return to normal without any intervention.
