Review Meta Analysis[Supplemental oxygen for the prevention of postoperative nausea and vomiting: a meta-analysis of randomized clinical trials].
Despite the development of antiemetic drugs, the incidence of postoperative nausea and vomiting remains between 20% and 30%. This meta-analysis examines the hypothesis that perioperative administration of supplemental oxygen reduces the incidence of these complications. ⋯ Supplemental oxygen reduces the incidence of postoperative vomiting. Administration of supplemental oxygen could be an effective method of reducing postoperative vomiting but does not replace current indications for pharmacologic prophylaxis.

Review[Minimally invasive cardiopulmonary monitoring with the PiCCO Plus system].
Insertion of a central venous catheter and an arterial catheter would be indicated in hemodynamically unstable or severely hypoxic patients in critical care units. In this setting, cardiorespiratory monitoring by transpulmonary thermodilution (TPTD) can be considered minimally invasive given that only a single arterial thermodilution catheter and a single central venous catheter are required to be connected to a specific monitor (the PiCCO Plus, Pulsion Medical Systems, Munich, Germany). ⋯ The technique can be managed by any health care professional. In hypoxic patients, TDTP identifies cases of pulmonary edema that might benefit from a negative fluid balance, evaluates pulmonary vascular permeability, facilitates our understanding of pathophysiologic mechanisms of hypoxemia, and predicts the likelihood of deleterious hemodynamic effects of positive end-expiratory pressures.

Randomized Controlled Trial Comparative Study[Anesthetic induction with nitrous-oxide-free sevoflurane in pediatric patients].
To evaluate the pediatric use of inhaled nitrous oxide (N2O)-free induction with sevoflurane for the purpose of protecting staff from exposure to workplace air pollution. ⋯ N2O-free anesthetic induction by tidal breathing of 8% sevoflurane provides similar anesthetic conditions (efficacy, safety, and rapid onset) without a higher incidence of adverse events. The use of N2O can therefore be avoided.
