The correlation between the merger of hyponatremia and malnutrition in the elderly acute cerebral infarction patients in intensive care unit / 中国综合临床

ABSTRACT

Objective To analyze relationship between elderly patients with acute cerebral infarction hyponatremia and their nutrition status.Methods One hundred and twenty patients were selected who hospitalized from January 2011 to December 2012.All the patiens' fasting venous blood samples were taken in the next day morning after hospitalied.and then performed the routine blood test,blood biochemical testing items,observed the level of serum sodium (Na),hemoglobin (Hb),total protein (TP),serum albumin (ALB),prealbumin (PA),C-reactive protein (CRP) and lymphatic cell counts (LY) were measured.According to the value of serum sodium,all patients were classified to lower sodium group (serum sodium ＜ 135 mmol/L,36cases),normal group (serum sodium range from 136 to 145 mmol/L,76 cases),and higher sodium group (serum sodium ＞ 145 mmol/L,8 cases).The results were statistically analyzed.Results The incidence of hyponatremia was 30％ (36/120).The levels of TP,ALB,PA,Hb and LY in lower sodium group were (50.35 ± 8.61) g/L,(28.35 ± 6.98) g/L,(89.96 ± 12.13) mg/L,(94.13 ± 25.36) g/L and (0.87 ±0.51) × 109 respectively,lower than that of normal group ((65.30 ± 5.48) g/L,(37.50 ± 3.63) g/L,(178.14 ± 18.61) mg/L,(124.87 ± 29.08) g/L,(1.67 ± 0.98) × 109 respectively,t =5.0897,7.1058,4.3216,3.8174,5.4237 respectively,P ＜ 0.01),but the level of CRP ((76.55 ± 49.95) mg/L) in lower sodium group was obviously higher than the normal serum sodium group ((21.33 ±35.04) mg/L,t =0.1287,P ＜ 0.01).The level of the serum sodium in ICU was related to the TP,ALB,PA,Hb and CRP(r =0.3176,0.4369,0.3695,0.2408,0.3612,0.0753 respectively,P ＜0.05).Conclusion The level of the merger of hyponatremia was correlated with malnutrition in the elderly acute cerebral infarction patients in ICU.We must strengthen the nutrition support treatment while correcting hyponatremia,in order to improve the clinical curative effect.
