BackgroundThere 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.ObjectiveTo 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.MethodRetrospective 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.ResultWe 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%, P < 0.001) higher using the L-piece than before weaning. The success of weaning a group using oxygen flow at 1-3 L/min was 92.2% and a group using oxygen flow at 4-6 L/min was 96.7%. There was no significant difference in the success rate between these groups (P = 0.25).ConclusionWeaning 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.
