无机磷是合成高能三磷酸腺苷所必需,因而创伤后低磷酸血症可能影响机体的能量代谢。肾上腺素所致血清磷酸盐减少,可由β-肾上腺素能阻断剂(心得安)而阻断。作者以前的实验证实,补充磷酸盐不能防止创伤后磷酸盐减少,这一减少主要是由于尿磷排泄增加,或由于创伤后儿茶酚胺增加引起磷酸盐重分布的缘故。 Inorganic phosphorus is necessary for the synthesis of high-energy adenosine triphosphate, so post-traumatic hypophosphatemia may affect the body’s energy metabolism. Epinephrine-induced decrease in serum phosphate may be blocked by beta-adrenergic blockers (propranolol). The authors previous experiments confirmed that supplementation with phosphate did not prevent the reduction of post-traumatic phosphate, primarily due to increased excretion of urinary phosphate or redistributed phosphate due to post-trauma catecholamines.
