Abstract:
Objective To explore the treatment opportunity of mechanical ventilation for acute severe organophosphorus pesticide poisoning patients with respiratory failure.Methods According to the different indications of mechanical ventilation,115 acute severe organophosphorus pesticide poisoning patients with respiratory failure were divided into the observation group A (40 cases),the observation group B(38 cases)and the control group(37 cases).The cure rate,aspiration pneumonia incidence,duration of mechanical ventilation,length of hospital stay of the three groups were analyzed.Results The cure rate of the observation group A(97.5％) was significantly higher than that of the control group(83.4％)and the observation group B (92.1％) (P ＜ 0.05 or P ＜ 0.01) ;The aspiration pneumonia of the observation group(2 cases) was significantly less than that of the control group(8 cases)(P ＜ 0.05) ;The hospitalization time [(4.46 ± 0.51) d,(7.11 ± 0.83) d] and the duration of mechanical ventilation [(55.40 ± 5.24)h,(79.47 ± 2.44) h] of the observation group A and the observation group B were significantly shorter than those of the control group [(10.40 ± 1.12) d,(100.30 ± 2.15) h] (all P ＜ 0.01) ; The hospitalization time and the duration of mechanical ventilation of the observation group A [(4.46 ± 0.51) d,(55.40 ± 5.24) h] were significantly shorter than those of the observation group B [(7.11 ± 0.83)d,(79.47 ± 2.44)h] (all P ＜ 0.01).Conclusion Respiratory rate ≥30 times/min and ＜ 34 times/min or ≤ 10 times/min,or spontaneous breathing weakened,and blood gas analysis prompted hypoxemia(60 mm Hg ＜ PaO2 ≤ 70 mm Hg)is best opportunity of mechanical ventilation for acute severe organophosphorus pesticide poisoning patients with respiratory failure.
