OTOLARYNGOLOGIST and anesthesiologist have perhaps more ground of mutual interest than many of the surgical specialists. They, of course, share a deep interest in the avoidance and treatment of operating room emergencies. Beyond this, however, they share a common concern with those problems which make endoscopy or intubation difficult. During 1967 several articles were published in the anesthesia literature which are of definite value to the otolaryngologist.

Operating Room Emergencies  The discussion of current concepts of hypovolemic shock by Boyan1 deserves special consideration. Blood loss of sufficient volume produces a proportional decrease in cardiac output and blood pressure. This is followed by myocardial depression because of decreased coronary artery blood flow and vasoconstriction which further compromises already inadequate tissue perfusion. Recent studies also suggest that decreased microcirculation is aggravated still more by red cell sludging, increase in blood viscosity, and intravascular coagulation. The resultant cell hypoxia and shift in
