A study of vecuronium bromide on severe bronchial asthma acute attack with breathing machine in conventional sedati / 中国基层医药

ABSTRACT

Objective To explore the effects of vecuronium bromide within 24 hours in severe bronchial asthma with acute attack with breathing machine in conventional sedatio.Methods Prospective study,double-blind randomized standard control,where 46 cases of patients of severe bronchial asthma with acute attack transferred to ICU using breathing machine in this year were randomly divided into the vecuronium bromide group (muscle relaxant group) and conventional sedation group (normal group) according to medical record number; Two groups of sample compositions were compared by x test,using two independent samples of t test to compare the effects the treatment and prognosis.Results After mechanical ventilation for 15min and 1-3h in muscle relaxant group,patients' vital signs were statistically analyzed,including respiration; Blood gas analysis parameters were as followspH,PaO2,PaCO2,SpO2 of these were improved compared with those in the conventional group (P ＜ 0.05) with statistically significant differences;Compared with the conventional group,in the muscle relaxant group,the retention time in ICU (146.20 ± 17.92) hours,(214.15 ± 22.21) hours,the using time of breathing machine (125.93 ± 16.23) hours,(192.89 ± 22.60) hours,and the dosage of glucocorticoid (2.61 ± 0.17) mg · kg-1 · d-1,(3.55 ± 0.26) mg · kg-1 · d-1,anticholinergic agent(6.25 ±0.51) μg · kg-1 · d-1,(10.64 ±0.75) μg · kg-1 · d-1 and β2 adrenergic receptor agonist (0.06 ±0.01)mg · kg-1 · d-1,(0.15 ±0.04)mg · kg-1 · d-1 were all reduced (all P ＜0.05) with statistically significant differences;The patients were smoothly transferred out of ICU,without the adverse events of mechanical ventilation and cardiovascular diseases.Conclusion The use of vecuronium bromide made the patients with severe bronchial asthma in routine sedation use of breathing machine rapidly correct the clinical symptoms and improve the off-period prognosis.
