Increased duration of mechanical ventilation is associated with decreased diaphragmatic force: a prospective observational study
INTRODUCTION Respiratory muscle weakness is an important risk factor for delayed weaning. Animal data show that mechanical ventilation itself can cause atrophy and weakness of the diaphragm, called ventilator-induced diaphragmatic dysfunction (VIDD). Transdiaphragmatic pressure after magnetic stimulation (TwPdi BAMPS) allows evaluation of diaphragm strength. We aimed to evaluate the repeatabili...
متن کاملNicardipine enhances diaphragmatic fatigue.
The effects of nicardipine, a calcium channel blocker, on diaphragmatic fatigue were studied in 20 anaesthetized, mechanically ventilated dogs divided into two groups: control group (Group C, n = 10) and nicardipine group (Group N, n = 10). Diaphragmatic fatigue was induced by intermittent supramaximal electric stimulation to bilateral phrenic nerves at a frequency of 20 Hz for 30 min. In Group...
متن کاملDiaphragmatic contraction during assisted mechanical ventilation.
Indirect evidence from airway pressure recordings in mechanically ventilated patients suggests that the diaphragm exhibits contractile activity beyond that required to trigger a ventilator-assisted breath. We used the diaphragmatic EMG to provide direct evidence of persistent contractile activity and studied the effects of alterations in ventilator-delivered flow rate and tidal volume on the du...
متن کاملDiaphragmatic strength during weaning from mechanical ventilation.
Respiratory muscle weakness is considered to be a factor in the inability to wean from mechanical ventilation. To assess this possibility, the present study examined the mechanical behavior of the diaphragm by measuring the change in transdiaphragmatic pressure (delta Pdi) during weaning. Nine "T-piece" weanings were carried out in seven patients with prior weaning failure and were terminated w...
متن کاملDiaphragmatic fatigue and breathing pattern during weaning from mechanical ventilation in COPD patients.
The medium-term outcome of weaning from mechanical ventilation in COPD patients is not easy to anticipate because a respiratory fatigue may eventually develop. We evaluated the diaphragmatic function and the breathing pattern during 40 weaning trials on 15 patients ventilated after acute respiratory failure. We formed two groups according to the success (group B, n = 18) or failure (group A, n ...
