严重烧伤患者应用重组人生长激素的时机--胰岛素样生长因子轴及血糖的变化分析

目的　分析重组人生长激素 (rhGH)对严重烧伤患者胰岛素样生长因子Ⅰ (IGF Ⅰ )、胰岛素样生长因子结合蛋白 3(IGFBP 3)及血糖的影响 ,寻找最佳用药时机。　方法　 4 0例严重烧伤患者随机分为对照组、伤后第 7～ 9天开始治疗组 (治疗组 1)和伤后第 10～ 14天开始治疗组 (治疗组2 )。观察伤后第 1、3、5、7、10、14、2 1天IGF Ⅰ、IGFBP 3、血糖动态变化并进行分析比较。结果　治疗组 1和治疗组 2应用rhGH后 ,上述 3项指标均有升高 ,其中IGFBP 3和血糖与对照组比较 ,差异有显著性意义 (P <0 .0 5 )。治疗组 1与治疗组 2比较 ,用药后各时相点的 3项指标差异无显著性意义 (P >0 .0 5 )。　结论　伤后第 7～ 9天是严重烧伤患者应用rhGH的较好时机。

Optimal time for the administration of rhGH in severely burned patients--analysis of the dynamic changes in IGF axis and blood sugar

OBJECTIVE: To investigate the effects of recombinant human growth hormone (rhGH) on the changes in serum insulin-like growth factor-I (IGF-I), IGF binding protein 3 (IGFBP-3) and blood sugar in severely burned patients, so as to validate the optimal time of rhGH administration. METHODS: Forty severely burned patients were enrolled in the study and were randomly divided into control (C), treatment 1 (rhGH given from 7 - 9 PBD, T1) and treatment 2 (rhGH from 10 - 14 PBD, T2) groups. The dynamic changes in serum IGF-I, IGFBP-3 and blood sugar on the 1, 3, 5, 7, 10, 14 and 21 PBDs in all 3 groups of burn patients were determined, analyzed and compared with one another. RESULTS: The serum IGF-I, IGFBP-3 and blood sugar levels in T1 and T2 groups were higher than those in C group after the use of rhGH, especially the IGFBP-3 and blood sugar (P < 0.05). There was no difference of all the indices between T1 and T2 groups. CONCLUSION: It might be optimal to give rhGH to severely burned patients during 7-9 PBDs.
