Fluid administration prevents renal dysfunction during hypotension under spinal anesthesia in a rat model.
Severe hypotension deteriorates renal functions and renal hemodynamics especially renal cortical blood flow. Systemic hypotension following high level spinal anesthesia may impair renal functions in spite of the blockade of renal sympathetic nerves that may help prevent vasoconstriction. Fluid loading is clinically applied for preventing hypotension but the effects on the changes of renal functions have not been studied. This study was designed to investigate the effects of fluid loading on systemic hemodynamics, renal hemodynamics and functions especially the blood distribution to renal cortex. ⋯ Fluid administration did not prevent hypotension following high level spinal anesthesia but might have beneficial effects on renal hemodynamics especially on the renal cortical circulation and urine flow rate.

Case ReportsPostoperative pulmonary edema, transfusion-related?--a case report.
Transfusion-related acute lung injury (TRALI) is a severe reaction between leukocyte antigen and antibody during transfusion of plasma-containing components. Recently, biologically active lipids have been also suggested to cause the disorder. It is a rare, but rather benign pulmonary edema. ⋯ Because the patient received blood products from 3 or 4 donors and the disorder was not recognized right away, the laboratory task for the definite diagnosis was difficult. Nevertheless, the patient had fully recovered in 36 hours after supportive therapies. Without identifying the blood donor implicated in the disorder, transfusion reactions or TRALI will be inevitable.

Randomized Controlled Trial Clinical TrialOral clonidine reduces myocardial ischemia in patients with coronary artery disease undergoing noncardiac surgery.
To access the clinical effect of clonidine on reduction of myocardial ischemia events in patients with history of coronary artery disease undergoing noncardiac surgeries. ⋯ We conclude that premedication with oral clonidine can significantly reduce the incidence of perioperative myocardial ischemia in patients with CAD undergoing noncardiac surgeries. The incidence of myocardial ischemia in these patients is rather high during perioperative period, which deserves our exceptional caution.

Randomized Controlled Trial Clinical TrialThe tracheal detecting-bulb: a new device to distinguish tracheal from esophageal intubation.
The tracheal detecting-bulb (TDB) is a diagnostic tool for confirmation of tracheal intubation. Capnography is also accepted as a standard way for such confirmation. The purpose of this investigation was to determine whether the results by TDB agreed with those by capnography. ⋯ The TDB is a valuable diagnostic technique for confirming tracheal intubation as it could correctly detect esophageal or tracheal intubation of the tracheal tube in all our 400 patients. The results of using TDB agree with the results of using capnography.
