Effects of doxophylline of different administration methods on weaning time of acute exacerbation of chronic obstructive pulmonary diseases of APACHEⅡ score

Objective To study effects of doxophylline of different administration methods on weaning time of acute exacerbation of chronic obstructive pulmonary diseases(AECOPD)of A-PACHEⅡ score.Methods 45 patients with AECOPD treated with mechanical ventilation and successful ventilator weaning were selected.In APACHEⅡ<20 patients,13 cases with doxo-fylline by continuous pump were in continuous pump group and 11cases in intravenous drip group;In APACHEⅡ≥20 patients,there were doxofylline by continuous pump with 11 cases and Doxo-fylline by intravenous drip with 10 cases,the effect of ventilator weaning time in different A-PACHEⅡscore between doxofylline by continuous pump and intravenous drip were observed.Re-sults The ventilator weaning time of doxofylline by continuous pump and intravenous drip were compared in APACHEⅡ<20,which was statistically significant difference (P <0.05).but there was no significant difference in APACHEⅡ≥20(P >0.05).Conclusion Ventilator weaning time of AECOPD is influenced by APACHEⅡ score.Continuous pump into doxofylline can obvi-ously relieve mechanical ventilation time in APACHEⅡ<20 and improve the rate of weaning time.
