Elders undergo approximately 40% of more than 1 million major abdominal operations annually. Yet evidence about recovery to preoperative levels of functional independence is limited. This study details course and predictors of functional recovery after elective major abdominal operations in the elderly. ⋯ The clinical course of functional recovery varied across different measures. Protracted disability at 6 months after operation was substantial. Several potentially modifiable factors consistently predicted recovery.

The purpose of this study was to determine if a hemoglobin-based oxygen carrier, HBOC-201 (Hemopure, Biopure Corp), alters endothelial function and nitric oxide physiology when used for hemorrhagic shock. ⋯ HBOC might be an alternative resuscitation agent in patients with hemorrhagic shock. Resuscitation with HBOC requires less volume than blood or crystalloid. These data suggest HBOC-201 has a vasoconstrictive effect that cannot be attributed soley to nitric oxide scavenging.

My colleagues and I studied alcohol and illicit drug intoxication in trauma fatalities and their association with the nature and severity of injuries. ⋯ There is a high rate of alcohol and illicit drug use in patients who die from trauma, especially penetrating trauma in men aged 15 to 50 years, who are Hispanic or African American. Victims with penetrating trauma and positive toxicology are considerably more likely to have no vital signs on admission than victims with negative toxicology. Pedestrians killed by automobiles who had positive screens have a higher incidence of severe abdominal injuries than victims with negative screens.
