Anesthesia: in cardiac emergencies

Contributor(s): John Dodam, Sheilah Robertson, Polly Taylor, Claire Waters

Introduction

  • Successful outcomes depend upon:
    • Prompt recognition of developing problems.
    • Rapid diagnosis of the underlying cause.
    • Taking appropriate measures to correct the problem quickly.
    • Monitoring of patient during anesthesia to avert accidents during and after anesthesia.
  • Main requirements during anesthesia:
    • Adequate delivery of oxygen to tissues (3-5 ml/kg/min).
    • Removal of waste products from tissues.
    • Failure to achieve the above can result in serious complications particularly tissue hypoxia and cell death.
    • Main requirement of the circulation is to deliver an adequate supply of well oxygenated blood to the tissues. Adequate perfusion of tissue is as important as oxygenation of the blood.
    • Mean blood pressure should be maintained above 70 mmHg.
