Background
There are many methods for weaning patients from mechanical ventilation. Using either a T-piece or CPAP are effective for weaning. Weaning using an L-piece is a strategy similar to using a T-piece, but uses less oxygen flow with air and has less dead space than a T-piece.
Objective
To determine whether adult patients with respiratory failure can be successfully weaned from a ventilator using an L-piece, including a study of factors that may affect the success or failure of weaning.
Method
Retrospective review of the medical records of a cohort of patients who had respiratory failure and were admitted to Wetchakarunrasm Hospital between January 1st, 2012 and September 30th, 2015.
Result
We found 143 cases matched the inclusion criteria. There was a 95.1% success in weaning adult patients with respiratory failure from a ventilator by using an L-piece. No vital signs before weaning and during L-piece weaning were significantly different, except for respiratory rate, which was 1.4 times/min (7.7%,
Conclusion
Weaning patients from mechanical ventilators using an L-piece is safe and has a success of 95.1%. This method of weaning can save oxygen use by reducing the flow of oxygen, which may be beneficial in patients with chronic obstructive pulmonary disease.
