ABSTRACT
Objective:To investigate the clinical efficacy of hemoperfusion in the treatment of severe organophosphorus poisoning and its effect on diaphragm function.Methods:Eighty-five patients with severe organophosphorus poisoning who received treatment in Affiliated Huxi Hospital of Jining Medical University (Shanxian Central Hospital), China between January 2018 and January 2020 were included in this study. They were randomly divided into treatment ( n = 43)and control ( n = 42) groups. The control group was given conventional treatment including gastric lavage, catharsis, and application of reactivators and anticholinergic drugs. The treatment group was subjected to three times of hemoperfusion, with an interval of 24 hours between two hemoperfusion interventions based on the conventional treatment used in the control group. Before and after three times of hemoperfusion, serum levels of cholinesterase (CHE), interleukin-6 (IL-6), arterial partial pressure of oxygen (PaO 2), and arterial partial pressure of carbon dioxide (PaCO 2) were measured. The Acute Physiology and Chronic Health Evaluation (APACHE) II score and oxygenation index (OI) in each group were calculated. Right diaphragmatic activity, diaphragmatic thickness at the end of inspiration (DTei) and diaphragmatic thickness at the end of expiration were measured by bedside ultrasound. The diaphragmatic thickening rate (DTF) and diaphragmatic rapid shallow breathing index (D-RSBI) were calculated. Serum CHE and IL-6 levels, OI, diaphragmatic activity, DTF and D-RSBI were compared between the treatment and control groups. The incidence of intermediate syndrome, tracheal intubation rate, 28-day mortality rate, and hospital stay were compared between the two groups. Results:Before hemoperfusion, there were no significant differences in serum levels of CHE and IL-6, OI, right diaphragmatic activity, DTF, and D-RSBI between the treatment and control groups (all P > 0.05). After three times of hemoperfusion, serum IL-6 level and D-RSBI in the treatment group were (37.9 ± 6.2) ng/L and (0.77 ± 0.20) times /min/mm, which were significantly lower than those in the control group [(45.9 ± 5.3) ng/L, (0.90 ± 0.16) times/min/mm ( t = -6.295, -3.382, P < 0.001, P = 0.001)]. Serum CHE level, OI, DE and DTF in the treatment group were (2.29 ± 0.52) kU/L, (264.5 ± 24.3) mmHg, (16.5 ± 1.9) mm, (27.2 ± 4.7) %, respectively, which were significantly higher than those in the control group [(1.96 ± 0.39) kU/L, (252.6 ± 27.2) mmHg, (14.3 ± 1.6) mm, (23.5 ± 4.1) %, t = 3.258, 2.141, 5.598, 3.877, all P < 0.05]. The incidence of intermediate syndrome, tracheal intubation rate, hospital stay in the treatment group were [4.7% (2/43)], [2.3% (1/43)] and [(11.8 ± 1.8) days], respectively, which were significantly lower than those in the control group [23.8% (10/42), 19.0% (8/42) and (12.9 ± 1.8) days, χ2 = 6.432, P = 0.011; χ2 = 6.276, P = 0.012; t = -2.932, P = 0.004]. There was no significant difference in 28-day mortality rate between the two groups ( P > 0.05). Conclusion:Hemoperfusion can improve diaphragmatic function, reduce inflammatory reaction and shorten hospital stay in patients with severe organophosphorus poisoning.
