Objective To compare the advantages between SmartCare weaning and protocoldirected weaning in COPD patients regarding five aspects including comfort degree of COPD patients in weaning stage, workload of medical staff, weaning success rate, weaning time, and complications associated with mechanical ventilation.
Methods COPD patients who’s planning to receive ventilation weaning were randomly divided into a SmartCare weaning group ( SC group) and a protocol-directed weaning group ( SBT group) . The comfort degree of patients and workload of medical staff were assessed by the visual analogue scale ( VAS) as the weaning plan started. 0 was for the most discomfort and maximal workload, and 10 was for the most comfort and minimal workload. Data fromthe following aspects had been recorded: times of blood gas analysis, weaning success rate, weaning time, self-extubation rate, the rate of re-intubation within 48 hours, and ventilator-associated pneumonia ( VAP) incidences.
Results 40 patients were selected and divided into the SC group ( n =19) and the SBT group ( n =21) . There was no significant difference in the enrolled age and APACHEⅡ between two groups. The VAS scores was higher in the SC group than that in the SBT group in the first three days ( P lt;0.01) . The weaning time was shorter in the SBT group than that in the SBT group [ ( 4.7 ±2.7) days vs. ( 5.5 ±3.2) days] , without significant difference between two groups ( P gt;0.05) . There were no differences in times of blood gas analysis, weaning success rate, weaning time, self-extubation rate, the rate of re-intubation within 48 hours, and ventilator-associated pneumonia ( VAP) incidences between two groups ( P gt; 0.05) .
Conclusion As compared with protocol-directed weaning, SmartCare weaning can increase comfort degree of patients and reduce the workload of medical staff with similar weaning success rate, weaning time, and complications associated with mechanical ventilation.
