title: The effects of nalorphine and Micoren on blood oxygenation and acid-base equilibrium in patients with myocardial infarction treated with neuroleptanalgesia II.
abstract: Sixty-five patients with myocardial infarction were observed for comparison of the values of nalorphine and Micoren in prevention of respiratory depression caused by fentanyl. The patients were divided into 4 groups receiving NLA II with or without nalorphine, morphine or Micoren. In all cases paO2, paCO2 and acid-base equilibrium were determined before and after administration of drugs. In the group receiving only NLA II paO2 fell in 50% of cases, in other groups receiving nalorphine or Micoren it increased in most cases. The paCO2 increased in most cases in groups receiving only NLA II or NLA II with nalorphine with or without morphine and respiratory acidosis developed in 4 cases. In the group receiving NLA II with Micoren paCO2 fell. The results indicate the necessity of administration of respiratory stimulants with NLA II and Micoren appears to be preferable to nalorphine in this respect.
