[Study of a new respiratory analeptic: injectable almatrine. Apropos of 22 cases of acute hypoventilation: respiratory activity and electroencephalographic control].

2620 is a respiratory analeptic which acts by stimulation of peripheral chemoreceptors. It was administered intravenously in 22 patients in acute respiratory insufficiency. Doses during the first hour varied between 0.

[Synchronous electric activity with inspiration in the vastus lateralis muscle of the anesthesied dog breathing spontaneously].

In the dog, under chloralose or pentobarbitone anesthesia and breathing spontaneously, a muscular electrical activity of low voltage synchronous with respiration was observed in m. vastus lateralis. The mean maximum amplitude of this activity is inversely linked with respiratory rate.
