Study on the trend of nutritional biochemical indexes in patients with paraquat poisoning / 中华急诊医学杂志

ABSTRACT

Objective To observe the nutritional biochemical indicators of paraquat poisoning patients, analyze and compare the nutritional status of patients and understand the changing trend of each indicator. Methods A total of 104 patients with acute paraquat poisoning who were admitted to the emergency department of the Second Hospital of Hebei Medical University from December 2015 to December 2017 were enrolled, and divided into the cure group (patients who survived >30 days) and the death group. Nutritional biochemical indicators including serum protein (ALB, PA, TP) and serum lipids (TCh, TG, LDL) were selected for dynamic observation. The observation time points were set as follows immediate treatment of poisoned patients (day 1 on admission), on day 4, 7, 10, 13 and 16 after admission, and on day 30 after follow-up. The nutritional biochemical indicators of the two groups on day 1 and 4 were statistically analyzed and compared by t test. The nutritional status of the patients in the cure group was analyzed, and the Repeated Measures Anova was performed to understand the trend of each indicator over time. Results In the cure group, the TP level decreased from (73.34±5.75)g/L on day 1 to (51.95±6.05)g/L on day 4, t=20.34, P<0.01; and the TCh level decreased from (4.37±0.98) mmol/L on day 1 to (3.03±1.01)mmol/L on day 4, t=7.56, P<0.01. In the death group, the TP level decreased from (72.25±8.80)g/L on day 1 to (49.07±5.48)g/L on day 4, t=12.38, P<0.01, and the TCh level decreased from (4.38±0.88)mmol/L on day 1 to (2.51±1.07) mmol/L on day 4, t=7.94, P<0.01. Compared with the cure group, serum levels of ALB, TP and TCh in the death group decreased greater from day 1 to day 4 (all P<0.05). In addition, dynamic observation of the indicators in the cure group within 16 days after admission showed that, after treatment, the levels of ALB and TP recovered slowly and were still lower than normal . While the levels of PA and lipid rose rapidly after 10 days of admission. Conclusions Paraquat poisoning seriously affects the nutritional status of patients, and the serum protein levels decline significantly and can not be recovered easily. Therefore, sufficient attention should be paid to the treatment, and timely and appropriate nutritional support should be provided.
