Hypoalbuminemia as seen in major burn injury results in widespread endothelial dysfunction. Base deficit provides the best estimate for degree of tissue anoxia. Acute blood loss describes anemia present in burn patients. Controversy focuses on the administration of protein-based colloids: whether to provide them, which solutions to use, and when to begin? The aim of this study was to determine whether alteration of gas exchange, excess base deficit, hypoalbuminemia and anemia could predict mortality in major burn patients, whether to provide protein-based colloids, and when to begin fluid resuscitation. The prospective study included 42 major burn patients. All the patients were admitted to the burn intensive care unit at Menoufia University Hospital. Serum albumin level, hemoglobin concentration, arterial blood gases and base deficit were measured at admission, third day and after one week. Average serum albumin on admission was 3.33 ± 0.44, after 3 days 2.85 ± 0.54 and after 1 week 2.46 ± 0.67 gm./dL, while hemoglobin concentration was 14.79 ± 2.13, 12.25 ± 1.99, and 10.24 ± 2.47 gm./dl respectively. However, base deficit was 5.75 ± 2.40, 5.24 ± 2.05 and 5.45 ± 2.76 respectively, with significant statistical difference (p<0.001) between the death and survivor groups. Binary logistic regression analysis for independent predictors of mortality declared that base deficit, albumin and hemoglobin serum levels were independent predictors for mortality with an odds ratio of 2.23, 95% CI, 1.66-16.75 for base deficit, 3.56, 95% CI, 1.88-12.59 for albumin and 2.21, 95% CI, 1.56-13.54 for hemoglobin. Hypoalbuminemia, anemia and excess base deficit can be used as prognostic factors for mortality in major burn patients.
严重烧伤时出现的低白蛋白血症会导致广泛的内皮功能障碍。碱缺失能最好地评估组织缺氧程度。急性失血描述的是烧伤患者出现的贫血情况。争议集中在基于蛋白质的胶体溶液的使用上:是否要使用、使用哪种溶液以及何时开始使用?本研究的目的是确定气体交换改变、碱缺失过多、低白蛋白血症和贫血是否能预测严重烧伤患者的死亡率,是否要使用基于蛋白质的胶体溶液以及何时开始液体复苏。这项前瞻性研究纳入了42例严重烧伤患者。所有患者均入住曼努菲亚大学医院烧伤重症监护病房。在入院时、第三天和一周后测量血清白蛋白水平、血红蛋白浓度、动脉血气和碱缺失。入院时平均血清白蛋白为3.33±0.44,3天后为2.85±0.54,1周后为2.46±0.67克/分升,而血红蛋白浓度分别为14.79±2.13、12.25±1.99和10.24±2.47克/分升。然而,碱缺失分别为5.75±2.40、5.24±2.05和5.45±2.76,死亡组和存活组之间存在显著统计学差异(p<0.001)。对死亡率的独立预测因素进行二元逻辑回归分析表明,碱缺失、白蛋白和血红蛋白血清水平是死亡率的独立预测因素,碱缺失的比值比为2.23,95%置信区间为1.66 - 16.75,白蛋白为3.56,95%置信区间为1.88 - 12.59,血红蛋白为2.21,95%置信区间为1.56 - 13.54。低白蛋白血症、贫血和碱缺失过多可作为严重烧伤患者死亡率的预后因素。
