The prevention and therapeutics effect of sodium bicarbonate with gastric lavage, atomization inhalation and intravenous injection on the patients with paraquat poisoning and pulmonary fibrosis induced by paraquat poisoning / 中华劳动卫生职业病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To observe the prevention effects of patients with lung exudation and pulmonary fibrosis induced by paraquat poisoning in sodium bicarbonate (SB) with gastric lavage, atomization inhalation and intravenous injection.</p><p><b>METHODS</b>To collect 38 patients with paraquat poisoning in hospital, after poison immediately with gastric lavage of 1.5% SB, and atomization inhalation of 5% SB 10~15 ml twice daily and intravenous injection of 5% SB twice a day, continuous application of 5~7 days. and the HRCT score and liver and kidney function was performed on patients with lung after treatment. And the extraction of 38 SB patients with previously untreated with SB for comparison.</p><p><b>RESULTS</b>Lung HRCT average score in 72 h, 7 d, 30 d on patients with paraquat poisoning untreated with SB reached 2.87, 3.12, 2.13, HRCT display shows that the appearance of the wear glass shadow, grid shadow, honeycomb shadow, and other signs of fibrosis. Average HRCT reached 1.95, 2.20, 1.67 on patients treated with SB,signs of lung exudation and fibrosis was significantly reduced,compare two groups,there was statistically significance (P<0.01). And compared to the control group, activity of serum alanine aminotransferase (ALT) and aspartic acid transaminase (AST) decreased significantly in group of paraquat poisoning with triple application of SB, the level of serum urea nitrogen (BUN) and creatinine (Cr) significantly decreased, the difference is statistically significant (P<0.01).</p><p><b>CONCLUSION</b>The triple application of SB can reduced the pulmonary fibrosis and effusion induced by paraquat poisoning,and protective effect on the function of liver and kidney is obvious, suggesting that the method for treatment of paraquat poisoning, prevention of paraquat lung and improve survival rate has the exact effect.</p>
