Hypercapnic acidosis attenuates lung injury induced by established bacterial pneumonia.
Hypercapnic acidosis protects against lung injury after ischemia-reperfusion, endotoxin-induced and ventilation-induced lung injury. The effects of hypercapnic acidosis in the setting of established pulmonary sepsis are not known. The authors investigated whether hypercapnic acidosis -- induced by adding carbon dioxide to inspired gas -- would be beneficial or deleterious in established Escherichia coli pneumonia in an in vivo model, in the presence and absence of antibiotic therapy. ⋯ Hypercapnic acidosis reduced the magnitude of the lung injury induced by established E. coli pneumonia.

Comparative Study
Manual editing of automatically recorded data in an anesthesia information management system.
Anesthesia information management systems allow automatic recording of physiologic and anesthetic data. The authors investigated the prevalence of such data modification in an academic medical center. ⋯ Editing of physiologic data automatically recorded in an anesthesia information management system is a common practice and results in decreased variability of intraoperative data. Further investigation may clarify the reasons for and consequences of this behavior.

The initial presentation of malignant hyperthermia (MH) may begin in the postoperative period. However, the maximal latency period between the end of anesthesia care and the onset of postoperative MH is unknown. The authors hypothesized that this latency period is short and is not manifested by hyperthermia as the initial presenting sign. The authors sought to test this hypothesis and to describe the clinical characteristics of postoperative MH by analysis of suspected cases in the North American Malignant Hyperthermia Registry. ⋯ Postoperative MH is uncommon, occurring in 10 of 528 suspected MH cases (1.9%) reported to the North American Malignant Hyperthermia Registry. Postoperative MH began shortly after completion of the anesthetic care. Hyperthermia was not a presenting sign of MH.
