Comparison of two weaning methods used in intensive care patients

Objective To investigate the weaning effect of SC and PSV methods in intensive care patients.Methods After fitting clinical weaning condition forty-one intensive care patients on mechanical ventilation were randomized into 2 groups: weaning with SC(n=21) or with PSV(n=20).The weaning time,total ventilation time,the manual setting changes while weaning and the rate of the reintubation,tracheotomy,pneumothorax and ventilator-associated pneumonia were recorded.Results The weaning time and total ventilation time was obviously shorter in SC group(P0.05);the manual setting changes while weaning was obviously less in SC(P0.05);No significant difference in the rate of the reintubation,tracheotomy,pneumothorax and ventilator-associated pneumonia was detected between the two groups.Conclusion SC method can shorten the weaning time,TVT so that to reduce the workload of physicians in ICU.
