This prospective study was undertaken to evaluate the efficiency of intercostal nerve block (ICNB) with 0.5% bupivacaine (Marcaine) for pain relief in patients with rib fractures and to correlate the degree of pain relief with changes in the peak expiratory flow rate (PEFR) and oxygen saturation (Sao2). ⋯ Significant increases in Sao2 and PEFR occur after ICNB with 0.5% bupivacaine, which also provides sustained analgesia, leading to improvement in respiratory mechanics.

An important objective of organized trauma care is to minimize delayed diagnoses and missed injuries. Discrepant interpretations of radiographs initially read by trauma surgeons represent a unique source of delayed diagnoses. The purpose of this study was to evaluate the efficacy of formalized radiology rounds as a component of the tertiary survey. ⋯ A small number of radiographic findings are not detected by trauma surgeons during the initial evaluation. Although these findings are not of major clinical significance, the majority required some alteration in care plan. Formalized radiology rounds promotes clinical efficiency through early identification of these injuries, which facilitates any necessary alteration in the care plan.

Despite improvements in the early resuscitation of the critically injured, mortality from multiple organ failure has remained stable, with the lung often the first organ to fail. Early intubation and mechanical ventilation predispose patients to the development of pneumonia and respiratory failure. Our objective was to establish a murine model of combined injury, consisting of burn/trauma and pulmonary sepsis with reproducible end-organ responses and mortality. ⋯ Although minimal perturbations were seen after burn or pulmonary infection alone, the combined insult of burn and pulmonary sepsis resulted in statistically significant hematopoietic changes with increased monocytopoiesis. Only the combined injury resulted in systemic sepsis and significantly increased mortality. We have developed a clinically relevant model of trauma and pulmonary sepsis that will allow further clarification of the inflammatory response after injury and infection.
