Abstract:
Objective:To explore the effect of different hemoperfusion times on the recovery of serum cholinesterase (ChE) in patients with severe acute oral organophosphorus pesticide poisoning (AOPP).Methods:This was a retrospective case-control study. Patients with severe AOPP admitted to our hospital were identified between January 2010 and December 2019. The clinical information of patients with severe AOPP was collected between January 2010 and December 2019, the patient's ChE vitality levels were collected on admission, at 1, 3 and 5 days after admission, and the sex, age, oral poison volume, and related treatments were recorded as well. The relationship between ChE, different HP treatment times and patients without HP treatment was analyzed by generalized estimation equations and multiple comparisons afterward.Results:A total of 159 patients with severe AOPP were included in our study. Among them, 60 (37.74%) patients were male and 99 (62.26%) were female, with a median age of 33 years old (range 13-75 years old). The median oral dose of OPs was 75 mL (range 15-500 mL). Multivariate analysis results showed that in the unadjusted generalized estimation equation, compared with patients without HP treatment, the average ChE value of patients with single HP treatment was 745.6 U/L higher (95% CI: 467.09 - 1024.1; P<0.01), the average ChE value of patients with 2 times HP treatment was 565.81 U/L higher (95% CI: 384.25-747.36; P<0.01), and the average ChE value of patients with 3 times HP treatment was 43.86 U/L higher (95% CI: 420.71-1 067.01; P<0.01), the differences were all statistically significant. After adjusting the amount of oral OPs at admission, age and PSS score in the multiple generalized estimation equations, the results showed that whatever single HP treatment or multiple HP treatment, the recovery rate of ChE was significantly faster than those without HP treatment. And the multiple comparison results of multiple models showed that the difference between 3 times HP treatment and 1 to 2 times HP treatment was not statistically significant, and the average difference between 2 times HP treatment and single HP treatment was also not statistically significant. Conclusions:Hemoperfusion therapy can accelerate the recovery rate of ChE in AOPP patients; Whatever single HP treatment or multiple HP treatments, the recovery rate of ChE in AOPP patients has no significant difference.
