ABSTRACT
Objective To investigate the effect of hemoperfusion (HP) on the activity of ChE in blood ofpatients with organophosphorus poisoning,and its toxicant clearance effect.Methods From January 2017 to January 2019,60 patients with organophosphorus poisoning in Shengjing Hospital Affiliated to China Medical University were divided into observation group and control group according to random number table method , with 30 cases in each group.The control group was treated with routine treatment ,while the observation group was treated with HP on the basis of routinetreatment.Thetherapeuticeffectsof thetwogroupswerecompared.Results Thedurationof mechanical ventilation and conscious awakening in the observation group were (3.07 ±1.14) d and (1.42 ±0.37) d,respectively, which were significantly shorter than those in the control group [(4.15 ±1.22) d,(2.01 ±0.58)d](t=3.543, 4.697,all P<0.05).The dosage of atropine in the observation group [(252.57 ±28.44) mg] was significantly less than that in the control group [(282.61 ±29.82)mg](t=3.993,P<0.05).The activity of cholinesterase after 12 h and 24 h of treatment was significantly higher than those before treatment (all P<0.05).After 12 h and 24 h of treatment,the cholinesterase activities in the observation group were (1128.64 ±152.49) U/L and (1422.08 ± 184.68)U/L,respectively,which were higher than those in the control group[(912.73 ±144.61) U/L and (1165.32 ± 173.27)U/L](t=5.627,5.553,all P<0.05).After 1 d and 3 d of treatment,the concentrations of organophosphorus poisons in the observation group were (1.08 ±0.30) mg/L and (0.62 ±0.18) mg/L,respectively,which were significantly lower than those in the control group[(1.32 ±0.35)mg/L and (0.84 ±0.27)mg/L](t =2.852, 3.713,all P<0.05).The incidences of rebound ,intermediate syndrome and multiple organ failure in the observation group were 3.33％(1/30),6.67％(2/30) and 13.33％(4/30),respectively,which were lower than those in the control group［23.33％(7／30),23.33％(7／30),36.67％(11／30)］(χ2 ＝5.192,3.278,4.356,all P ＜0.05).Conclusion HP has obvious effect on the activity of ChE and the concentration of blood poisons in patients with organophosphorus poisoning.It is worthy of popularizing and applying in clinic.
ABSTRACT
Objective@#To investigate the effect of hemoperfusion (HP) on the activity of ChE in blood of patients with organophosphorus poisoning, and its toxicant clearance effect.@*Methods@#From January 2017 to January 2019, 60 patients with organophosphorus poisoning in Shengjing Hospital Affiliated to China Medical University were divided into observation group and control group according to random number table method, with 30 cases in each group.The control group was treated with routine treatment, while the observation group was treated with HP on the basis of routine treatment.The therapeutic effects of the two groups were compared.@*Results@#The duration of mechanical ventilation and conscious awakening in the observation group were (3.07±1.14) d and (1.42±0.37) d, respectively, which were significantly shorter than those in the control group[(4.15±1.22) d, (2.01±0.58)d](t=3.543, 4.697, all P<0.05). The dosage of atropine in the observation group[(252.57±28.44)mg]was significantly less than that in the control group[(282.61±29.82)mg](t=3.993, P<0.05). The activity of cholinesterase after 12 h and 24 h of treatment was significantly higher than those before treatment (all P<0.05). After 12 h and 24 h of treatment, the cholinesterase activities in the observation group were (1 128.64±152.49)U/L and (1 422.08±184.68)U/L, respectively, which were higher than those in the control group[(912.73±144.61)U/L and (1 165.32±173.27)U/L](t=5.627, 5.553, all P<0.05). After 1 d and 3 d of treatment, the concentrations of organophosphorus poisons in the observation group were (1.08±0.30)mg/L and (0.62±0.18)mg/L, respectively, which were significantly lower than those in the control group[(1.32±0.35)mg/L and (0.84±0.27)mg/L](t=2.852, 3.713, all P<0.05). The incidences of rebound, intermediate syndrome and multiple organ failure in the observation group were 3.33% (1/30), 6.67% (2/30) and 13.33% (4/30), respectively, which were lower than those in the control group[23.33% (7/30), 23.33% (7/30), 36.67% (11/30)](χ2=5.192, 3.278, 4.356, all P<0.05).@*Conclusion@#HP has obvious effect on the activity of ChE and the concentration of blood poisons in patients with organophosphorus poisoning.It is worthy of popularizing and applying in clinic.
