Appropriate and timely antibiotic therapy to treat pneumonia in trauma patients is extremely important. We evaluated the incidence and microbiology of pneumonia stratified by days postadmission and risk factors. ⋯ Unanticipated pathogens were isolated in each class of pneumonia. The clinician must be aware of significant risk factors that may predispose patients to pathogens that are not ordinarily covered with standard antibiotic therapy.

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.

The initial evaluation and treatment of patients with multiple injuries are challenging. However, little is known about thoracolumbar fractures in patients with multiple injuries. We aimed to determine the incidence of missed injuries of the thoracolumbar spine in patients with multiple injuries, to examine the reasons for the delay in diagnosis, and to study the selection of treatment options in the management and timing of surgical intervention. ⋯ Patients with blunt trauma caused by high-energy impact injuries are much more likely to have thoracolumbar fractures even if injuries elsewhere have been noted. Further radiographic studies of the thoracolumbar spine should be performed if there is any question related to a thorough and systematic examination. Choice of treatment options of thoracolumbar fractures in patients with multiple injuries is not different from that in patients with no associated injuries to other systems. Appropriate timing of thoracolumbar fracture fixation in patients with multiple injuries should not be dependent on a rigid protocol.

Unexpected immunomodulatory effects of colloids and crystalloids prompted an investigation of albumin's ability to prevent bone marrow (BM) suppression following trauma/hemorrhagic shock (T/HS: laparotomy + MAP 30 for 90 mins). ⋯ Small doses of albumin fully restore CFU-GM and BFU-E to sham values. We postulate that the binding of circulating toxic factors by albumin may play a role in this prevention of T/HS-induced BM suppression.
