A comparison of controlled ventilation with a noninvasive ventilator versus traditional mask ventilation.

After induction, but before intubation, many general anesthesia patients are manually bag-mask ventilated. The objective of this study was to determine the efficacy of bag-mask ventilation (MkV) of an anesthetized patient versus mask ventilation using a noninvasive ventilator (NIV). We hypothesized that feedback-controlled, mask ventilation via NIV is more efficacious and safer.

Effect of patient position on endotracheal cuff pressure in mechanically ventilated critically ill patients.

Background: Endotracheal tube cuff pressure must be maintained within 20-30mHO to prevent complications. There is limited literature reporting the impact of nursing care on endotracheal cuff pressure. However, few studies have reported the effect of nursing care on endotracheal cuff pressure.

[Controversy in the treatment of acid-base abnormalities].

Sodium bicarbonate has been standard therapy for the treatment of acidosis. In lactic acidosis and hypercapnic acidosis, however, there is no clinical data supporting its effectiveness. We reviewed the literature of the efficacy of sodium bicarbonate on lactic acidosis and hypercapnic acidosis.

Protective action of D-ribose against renal injury caused by ischemia and reperfusion in rats with transient hyperglycemia.

Hyperglycemia amplifies the inflammatory state after ischemia/reperfusion (I/R), and activated neutrophils have been implicated in the development of I/R-induced renal injuries. D-ribose is a naturally occurring monosaccharide found in all living cells. In this study, we examined whether D-ribose attenuates I/R-induced renal injury by reducing neutrophil activation in rats with transient hyperglycemia.
