Abstract:
Objective To analyze the emergency treatment protocols and nursing measures for patients with diquat and paraquat poisoning,aiming to provide references for updating future clinical practice.Methods A retrospective study was conducted involving 53 patients with diquat and paraquat poisoning admitted to the department of emergency of the First Affiliated Hospital of Wenzhou Medical University from January 1,2019,to December 31,2023.The patients were divided into survival and death groups based on their prognosis.Clinical data were collected to compare organ dysfunction,the proportion of hemoperfusion(HP),average number of HP sessions,the proportion of blood purification,average duration of blood purification,and the proportion of HP combined with continuous renal replacement therapy(CRRT)between two groups of patients with different prognoses.Results Among the 53 patients,27(50.94%)were male and 26(49.06%)were female;with an age range of 14 to 86 years and a mean age of(38.13±19.68)years.Fifty-two cases were due to intentional ingestion,and 1 was accidental.The detected blood concentrations of diquat ranged from 57.38 to 119762.00 μg/L,while those of paraquat ranged from 60.12 to 71 244.89 μg/L.Forty patients developed multiple organ dysfunction syndrome(MODS),with 38 ultimately progressing to multiple organ failure,primarily affecting the gastrointestinal tract,kidneys,and liver.After aggressive treatment and nursing,the blood concentrations of 13 patients(24.53%)dropped below 50 μg/L,and they were discharged after 4 to 34 days of hospitalization.Thirty-two patients'families opted for withdrawal of treatment and discharge,with subsequent confirmation of death after follow-up,hospital stay:1-4 days.Eight patients died in-hospital,hospital stay:1-3 days,resulting in a total mortality rate of 40 cases(75.47%).Compared to the survival group,the death group had significantly higher rate of neurological,renal,respiratory,and liver injuries[neurological:90.00%(36/40)vs.15.38%(2/13),renal:95.00%(38/40)vs.69.23%(9/13),respiratory:97.50%(39/40)vs.30.77%(4/13),liver injury:85.00%(34/40)vs.46.15%(6/13),all P<0.05].Furthermore,the death group had significantly lower average number of HP sessions and average duration of blood purification compared to the survival group[average number of HP sessions:4.35±2.42 vs.6.62±1.17,average duration of blood purification time(days):1.53±1.09 vs.5.23±3.90,both P<0.05].Conclusions Poisoning with a mixture of diquat and paraquat is life-threatening and associated with a high mortality.In addition to systematic treatment,individualized and dynamic nursing support should be provided,including close monitoring of the manifestations and laboratory indicators of affected organ systems.Therefore,optimization treatment protocols during the peak mortality period may help reduce mortality in patients with diquat and paraquat poisoning.
