Vancomycin-Resistant Enterococci in Patients Attending for Colonoscopy: An Estimate of Community Prevalence.

Aims Ireland has the highest vancomycin-resistant Enterococcus faecium (VRE) bloodstream infection prevalence in Europe. Two patterns of VRE carriage are recognised. European, with widespread community prevalence and North American, where carriage is predominantly nosocomial.

Hypercapnic acidosis reduces oxidative reactions in endotoxin-induced lung injury.

Background: Hypercapnic acidosis frequently occurs when patients with acute lung injury are initially ventilated with low tidal volume "protective" strategies. Hypercapnic acidosis per se, in the absence of any change in tidal volume or airway pressure, is protective when instituted before the onset of injury. However, the mechanisms by which hypercapnic acidosis confers this protection are incompletely understood, in particular, the effects on pulmonary oxidative reactions, which are potent mediators of tissue damage, have not been previously examined in vivo.

Infection-induced lung injury is worsened after renal buffering of hypercapnic acidosis.

Objective: Prolonged hypercapnia is commonly encountered during the treatment of acute respiratory distress syndrome and acute respiratory failure attributable to other causes with protective ventilation strategies. In these circumstances, compensatory renal buffering returns pH to normal establishing a condition of buffered hypercapnia. It is also common intensive care practice to correct the pH more rapidly using bicarbonate infusions.

Intravenous fluid loading with or without supplementary dextrose does not prevent nausea, vomiting and pain after laparoscopy.

Purpose: To examine the effects of iv compound sodium lactate (CSL) with and without caloric supplementation with dextrose on nausea, vomiting and pain following general anesthesia for laparoscopy.

Methods: We compared iv fluid loading with and without supplementary dextrose for the prevention of postoperative nausea and vomiting (PONV). In a prospective double-blinded controlled trial, 120 ASA I female patients undergoing elective gynecological laparoscopy were randomized to one of three groups, and received either: (a) CSL 1.
