[Favorable results of nocturnal nasal positive-pressure ventilation in 64 patients with neuromuscular disorders; 5-year experience].
Evaluation of the effectiveness of chronic nightly mechanical ventilation through a nasal mask system in patients with neuromuscular diseases or patients with thorax malformations or COPD.. Centre for Home Mechanical Ventilation, University Hospital Utrecht.. Retrospective study.. During the period June 1988-May 1993, 64 patients (11-69 years old) were treated with nasal mask ventilation during the night: 37 men (most of whom had Duchenne's disease (18) and 27 women (most of whom had (post-polio) kyphoscoliosis (n = 13). The effects on arterial blood gases were analysed. Complications during use of the nasal mask systems were recorded.. The duration of the nasal mask ventilation was 2 to 56 months. Arterial PCO2 and PO2 improved during the night as well as by day during spontaneous respiration. The most common problems were necrosis of the skin of the bridge of the nose, leakage of air through the mouth or insufflation of air into the stomach. After the start of the mechanical ventilation quality of life improved considerably.. Nasal ventilation at night is sufficient and simple. The installation of a tracheostoma can be postponed or avoided with this non-invasive kind of ventilation.

Non-invasive assessment of respiratory muscle strength in patients with previous poliomyelitis.
In patients with poliomyelitis, respiratory failure requiring ventilatory support may occur during the acute illness. Some patients continue to require long-term nocturnal ventilatory support; others are weaned but subsequently require support because of a late deterioration in ventilatory function.. To assess the sensitivity of sniff nasal inspiratory pressure (SNIP) to post-poliomyelitis respiratory muscle weakness and to assess the relationship between the respiratory muscle strength and the need for ventilatory support in patients with previous poliomyelitis (post-polio patients).. Respiratory muscle strength was measured in 50 post-polio patients. Tests included forced vital capacity (FVC), maximum inspiratory and expiratory pressures (MIP and MEP), and SNIP.. Twenty-one patients used non-invasive nocturnal ventilatory support (NIV group) compared to 29 on no support (non-NIV group). The percentage predicted FVC was significantly lower in the NIV group compared to the non-NIV group (P=0.01). Similarly, the percentage predicted MIP was significantly lower in NIV group (P=0.007). Low SNIP values (both absolute value and percentage predicted) were associated with the need for ventilatory support (P<0.001). Of the patients requiring no support, those who had been ventilated during the acute episode of poliomyelitis had a significantly lower SNIP than those who had never been ventilated (P=0.04).. Post-polio patients who are currently on nocturnal ventilation have significantly lower FVC, MIP and SNIP compared to currently non-ventilated patients. Non-ventilated patients who were ventilated during the acute episode of poliomyelitis have significantly weaker respiratory muscle strength than patients who were never ventilated. This study indicates that SNIP is more sensitive to post-polio respiratory muscle weakness than other non-invasive tests. Thus measurement of SNIP is a valuable tool for monitoring the progression of respiratory muscle weakness due to previous poliomyelitis and this can be applied to other neuromuscular disorders.
