Stimulants in Chronic Respiratory Failure
نویسندگان
چکیده
The effects of slow intravenous infusion of three different respiratory stimulants (dimeftine, nikethamide and prethcamide) on minute and alveolar ventilation, blood gases and pH were studied in 18 patients with chronic pulmonary emphysema and chronic respiratory failure. For a more accurate assessment of the results of the double blind controlled trial, a factorial design in a Youden square scheme was employed. Respiratory rate, tidal volume, minute ventilation, arterial Po0, pH and heart rate failed to show significant changes after the intravenous infusion of the drugs. The other parameters studied (dead space, alveolar ventilation, CO2 output, Paco0) showed some differences but these were temporally similar for the three drugs. As improvement in respiratory and blood gases data was transient and slight and undesirable side-effects constant, it is concluded that the use of respiratory stimulants in management of chronic respiratory failure cannot be recommended.

Chronic obstructive pulmonary disease v 9: Management of ventilatory failure in COPD
MANAGEMENT OF RESPIRATORY FAILURE DURING ACUTE EXACERBATIONS OF COPD The purpose of managing respiratory failure/ supporting ventilation in acute exacerbations of chronic obstructive pulmonary disease (COPD) is to prevent tissue hypoxia and control acidosis and hypercapnia while medical treatment works to maximise lung function and reverse the precipitating cause of the exacerbation. There are ...

CUTE VENTILATORY FAILURE, GENERALly defined as an abrupt increase in carbon dioxide tension, is a common complication of chronic obstructive lung disease. When severe and uncompensated, coma and death may result unless heroic measures are taken to assist or stimulate respiration. However, milder episodes of carbon dioxide retention also occur in patients with the “emphysema-bronchitis syndrome,...
