Airway troubles related to the double-lumen endobronchial tube in thoracic surgery.
Several case reports indicate critical respiratory complications in relation to the double-lumen endobronchial tube (DLT). A prospective survey for the airway problems in using the DLT is presented. ⋯ Most of the DLT obstructions were associated with withdrawal malposition. Great attention to DLT displacement and airway deformity is advised.

Differential effects of ketamine and MK-801 on A-fiber and C-fiber responses of spinal wide dynamic range neurons in the cat.
To clarify whether ketamine suppresses both A-fiber-and C-fiber-mediated pain and to compare the effects of ketamine with those of MK-801. ⋯ Intravenous ketamine may suppress both A-and C-fiber-mediated pain at a subanesthetic dose. This finding could be a scientific basis for the usefulness of ketamine during clinical procedures such as dressing changes or débridement of the burned patient.

Detection of acetazolamide-induced increase in organ blood flow in rabbits by laser flowmetry.
We investigated the mechanism by which inhibition of carbonic anhydrase (CA) increases organ blood flow. ⋯ Administration of AZ increased rBF in the tissues and organs that contained large amounts of CA without increasing the cardiac output or decreasing the pH, which suggests a direct local effect. A differential sensitivity to the retention of CO2 is suggested as a possible mechanism of the selectivity of the increase in rBF.
