Comparative Study
A Comparison of Red Cell Rejuvenation versus Mechanical Washing for the Prevention of Transfusion-Associated Organ Injury in Swine.
We evaluated the effects of two interventions that modify the red cell storage lesion on kidney and lung injury in experimental models of transfusion. ⋯ Reversal of the red cell storage lesion by rejuvenation reduces transfusion-associated organ injury in swine.

An Anesthesiologist's Perspective on the History of Basic Airway Management: The "Progressive" Era, 1904 to 1960.
This third installment of the history of basic airway management discusses the transitional-"progressive"-years of anesthesia from 1904 to 1960. During these 56 yr, airway management was provided primarily by basic techniques with or without the use of a face mask. ⋯ Basic airway management success was essential for traditional inhalation anesthesia (ether, chloroform) and for the use of the new anesthetic agents (cyclopropane, halothane) and intravenous drugs (thiopental, curare, succinylcholine). By the end of the era, the superiority of intermittent positive pressure ventilation to spontaneous ventilation in anesthesia and negative pressure ventilation in resuscitation had been demonstrated and accepted, and the implementation of endotracheal intubation as a routine technique was underway.

Observational Study
Incidence of Artifacts and Deviating Values in Research Data Obtained from an Anesthesia Information Management System in Children.
Vital parameter data collected in anesthesia information management systems are often used for clinical research. The validity of this type of research is dependent on the number of artifacts. ⋯ Not all values in anesthesia information management systems are valid. The incidence of artifacts stored in the present pediatric anesthesia practice was low for heart rate and oxygen saturation, whereas noninvasive and invasive blood pressure and end-tidal carbon dioxide had higher artifact incidences. Deviating values are more often artifacts than values in a normal range, and artifacts are associated with the phase of anesthesia and anesthetic technique. Development of (automatic) data validation systems or solutions to deal with artifacts in data is warranted.
