ABSTRACT
<p><b>OBJECTIVE</b>To explore the clinical efficacy of early application of sequential gastrointestinal lavage in patients with acute paraquat poisoning by analyzing the clinical data of 97 patients.</p><p><b>METHODS</b>A total of 97 eligible patients with acute paraquat poisoning were divided into conventional treatment group (n = 48) and sequential treatment group (n = 49). The conventional treatment group received routine gastric lavage with water. Then 30 g of montmorillonite powder, 30 g of activated charcoal, and mannitol were given to remove intestinal toxins once a day for five days. The sequential treatment group received 60 g of montmorillonite powder for oral administration, followed by small-volume low-pressure manual gastric lavage with 2.5%bicarbonate liquid. Then 30 g of activated charcoal, 30 g of montmorillonite powder, and polyethylene glycol electrolyte lavage solution were given one after another for gastrointestinal lavage once a day for five days. Both groups received large doses of corticosteroids, blood perfusion, and anti-oxidation treatment. The levels of serum potassium, serum amylase (AMY) alanine aminotransferase (ALT), total bilirubin (TBIL), blood urea nitrogen (BUN), creatinine (Cr), lactate (Lac), and PaO₂of patients were determined at 1, 3, 5, 7, and 10 days. Laxative time, mortality, and survival time of dead cases were evaluated in the two groups.</p><p><b>RESULTS</b>The incidence rates of hypokalemia (<3.5 mmol/L) and AMY (>110 U/L) were significantly lower in the sequential treatment group than in the conventional treatment group (P < 0.05). There were no significant differences in the incidence of ALT (>80 U/L), TBIL (>34.2 µmol/L), BUN (>7.2 mmol/L), and Cr (>177 µmol/L) between the two groups (P>0.05). However, the highest levels of ALT, TBIL, BUN, Cr, and Lac were significantly lower in the sequential treatment group than in the conventional treatment group (P < 0.05). Moreover, the sequential treatment group had significantly lower incidence of PaO₂(<60 mmHg), shorter average laxative time, lower mortality, and longer survival time of dead cases than the conventional treatment group (P < 0.05).</p><p><b>CONCLUSION</b>The early application of sequential gastrointestinal lavage can shorten laxative time, alleviate organ damage in the liver, kidney, lung, and pancreas, reduce mortality, and prolong the survival time of dead cases in patients with acute paraquat poisoning.</p>
