目的观察脑外伤后低钠血症患者急性期临床经过及近期预后表现。方法连续选择近期住院的脑外伤患者133例,检测住院期间血、尿钠值,并观察急性期临床经过和预后表现。低钠血症诊断标准为住院期间血钠≤125mmol/L和尿钠测定≥80mmol/24h。结果133例脑外伤中确诊低钠血症患者47例(35.34%),血钠正常患者86例(对照组)。低钠血症组的平均意识障碍时间、CT阳性发现例数、平均血肿量、中线移位例数和平均住院天数均明显高于对照组,而入院时GCS评分和出院时ADL评分却明显低于后者(P均<0.05～0.01)。结论低钠血症可明显影响脑外伤患者急性期临床经过及近期预后。
Objective To observe the clinical and recent prognosis of patients with hyponatremia after acute traumatic brain injury. Methods A total of 133 consecutive traumatic brain injury patients were selected. The blood and urine sodium levels during hospitalization were measured. The clinical course and prognosis in acute phase were observed. The diagnostic criteria for hyponatremia were serum sodium ≤125mmol / L and urinary sodium ≥80mmol / 24h during hospitalization. Results In the 133 traumatic brain injury patients, 47 cases (35.34%) were diagnosed as hyponatremia and 86 cases were normal sodium (control group). The average time of unconsciousness, the number of CT positive findings, the average number of hematomas, the number of midline shift and the average length of stay in hyponatremia group were significantly higher than those in control group, but the GCS scores on admission and the ADL scores on discharge were significantly lower The latter (P <0.05 ~ 0.01). Conclusions Hyponatremia can significantly affect the clinical course and prognosis of acute traumatic brain injury patients.
