早期全肠外营养及肠内、外混合营养对神经外科危重患者免疫功能的影响

目的探讨早期给予全肠外营养（TPN）及肠内营养（EN）、肠外营养（PN）混合支持对神经外科危重患者免疫功能的影响。方法采用前瞻性对照研究将神经外科危重患者按入院顺序随机分为TPN组及EN＋PN组，并对比营养支持前后两组CD3、CD4、CD8、CD4／CD8、CD3／CD25、IgA、IgG、IgM、血清白蛋白的变化。结果给予神经外科危重患者两种营养支持均可提高其CD3、CD4、CD8及CD3＋／CD25＋比值（P〈0．05，P〈0．01）；两种营养支持方式均可显著升高IgA、IgG、IgM、（P〈0．05）及血清白蛋白浓度（P〈0．01）。与TPN组比较，EN＋PN组CD3、CD4、CD8、CD4／CD8比值、IgA、IgG、IgM浓度及血清白蛋白水平均显著升高（P〈0．05，P〈0．01）。结论早期TPN及EN＋PN支持均可促进神经外科危重患者免疫功能的恢复及提高，EN＋PN的作用优于TPN，对于神经外科危重患者应早期给予营养支持治疗。

Effect of total parenteral nutrition or early enteral and parenteral nutrition on immune function in critically ill neurosurgical patients

Objective To explore the effect of support with total parenteral nutrition(TPN)or early enteral and parenteral nutrition(EN+PN)on immune function of critically ill neurosurgical patients.Methods In this prospective control study,patients were divided inte TPN group and EN+PN group based on the timing of admission.The changes of immunological indicators including CD3,CD4,CD8,CD4/CD8,CD3/CD25,IgA,IgG,IgM,and serum protein before and after nutritional support were compared.Results The percentage of T lymphocyte subsets CD3,CD4,and CD8,the ratio of CD3+/CD25+,the plasma leveh of IgA,IgM,and IgG,and the serum protein were significantly increased after nutrifional supports(P<0.05,P<0.01).However,compared with the TPN group,the percentages of T lymphocyte subsets(CD3,CD4,and CD8),the ratio of CD4+/CD8+,the plasma levels of IgA,IgM,and IgG,and the serum protein were significantly higher in EN+PN group(P<0.05,P<0.01).Conclusions Both TPN and EN+PN can promote the recovery of immune function,while EN+PN is superior to TPN.Early nutritional support should be provided to critically ill neurosurgical patients.
