Rapid disuse atrophy of diaphragm fibers in mechanically ventilated humans.
BACKGROUND The combination of complete diaphragm inactivity and mechanical ventilation (for more than 18 hours) elicits disuse atrophy of myofibers in animals. We hypothesized that the same may also occur in the human diaphragm. METHODS We obtained biopsy specimens from the costal diaphragms of 14 brain-dead organ donors before organ harvest (case subjects) and compared them with intraoperati...
متن کاملDiaphragm weakness in mechanically ventilated critically ill patients
INTRODUCTION Studies indicate that mechanically ventilated patients develop significant diaphragm muscle weakness, but the etiology of weakness and its clinical impact remain incompletely understood. We assessed diaphragm strength in mechanically ventilated medical ICU patients, correlated the development of diaphragm weakness with multiple clinical parameters, and examined the relationship bet...
متن کاملGastro-oesophageal reflux in mechanically ventilated preterm infants.
Long duration oesophageal pH recordings were performed on 42 mechanically ventilated and parenterally fed preterm infants for a mean (SD) of 94 (28) hours. Their mean (SD) gestational age was 31.5 (2.6) weeks and birth weight 1514 (448) g. Their mean postnatal age was 19 (10) hours at the onset of pH recording, which was performed with the babies supine. The mean hourly values for the total num...
متن کاملChest Physiotherapy in Mechanically Ventilated Infants: a Narrative Literature Review
Chest physiotherapy is well supported for the treatment of respiratory complications in adults undergoing mechanical ventilation in intensive care. This narrative literature review aims to establish the current evidence available regarding chest physiotherapy in paediatric intensive care populations, specifically infants. Due to anatomical and physiological differences infants have greater inci...
متن کاملTime constant/volume relationship of passive expiration in mechanically ventilated ARDS patients.
Since the adult respiratory distress syndrome (ARDS) lung is known to be inhomogeneous, one could expect an uneven distribution of expiratory time constant during uninterrupted mechanical ventilation. We investigated the time constant/volume relationship of passive expiration, and their modification by external resistive elements. In 12 paralysed intubated ARDS patients, we determined the expir...
