Maintenance of postsurgical tissue oxygenation depends on the ability of the specific tissue to recruit perfusion and oxygen (O(2)) supply. When native O(2)-carrying capacity is lacking, fluids to improve O(2)-carrying capacity based in hemoglobin (Hb) could prevent partially ischemic tissue hypoxia by increasing O(2) release from the remaining red blood cells. ⋯ Results suggest the existence of an optimal concentration of low O(2)-affinity acellular Hb to increase oxygenation of partially ischemic tissue during anemic conditions.

Randomized Controlled Trial
Randomized, double-blind, placebo-controlled trial using lidocaine patch 5% in traumatic rib fractures.
The lidocaine patch 5% was developed to treat postherpetic neuralgia. Anecdotal experience at our institution suggests the lidocaine patch 5% decreases narcotic usage in patients with traumatic rib fractures. This trial was developed to define the patch's efficacy. ⋯ The lidocaine patch 5% does not significantly improve pain control in polytrauma patients with traumatic rib fractures.

Our previous Delphi study identified several audit filters considered sensitive to deviations in prehospital trauma care and potentially useful in conducting performance improvement, a process currently recommended by the American College of Surgeons Committee on Trauma. This study validates 2 of those proposed audit filters. ⋯ Failure of EMS to document basic measures of scene physiology is associated with increased mortality. This deviation in care can serve as a sensitive audit filter for performance improvement. The need by BLS for ALS assistance was not associated with increased mortality.

Comparative Study
Comparison of hospital performance in nonemergency versus emergency colorectal operations at 142 hospitals.
Quality improvement efforts have demonstrated considerable hospital-to-hospital variation in surgical outcomes. However, information about the quality of emergency surgical care is lacking. The objective of this study was to assess whether hospitals have comparable outcomes for emergency and nonemergency operations. ⋯ Hospitals with favorable outcomes after nonemergency colorectal resections do not necessarily have similar outcomes for emergency operations. Hospitals should specifically examine their performance on emergency surgical procedures to identify quality improvement opportunities and focus quality improvement efforts appropriately.

Information-based scoring systems predictive of outcomes of midline laparotomy are needed; these systems can support surgical decisions with the aim of improving patient outcomes and quality of life, and reducing the risk of secondary surgical procedures. ⋯ A statistically valid, straightforward, and clinically useful predictive model was developed for estimating the risk of incisional hernia within 6 months of midline laparotomy. Prospective independent validation of this model appears indicated.
