Although hemorrhage or trauma (laparotomy) alone in mice produces a marked immunosuppression for 3 to 4 days and trauma plus hemorrhage produces immune depression for 5 days after resuscitation, it remains unknown when the immune functions return to normal after trauma-hemorrhage and whether lymphocyte and macrophage functions are similarly affected by trauma-hemorrhage. ⋯ The results indicate that a more severe and prolonged immunodepression occurs after combined trauma and hemorrhage than after trauma or hemorrhage alone.

Recent literature suggests that patients who undergo emergent tube thoracostomy in the field are at increased risks for complications. This study evaluates indications, complications, and effectiveness of field placement of chest tubes by an aeromedical service. ⋯ Prehospital chest tube thoracostomy is safe, effective, and associated with low morbidity. Nontherapeutic chest tube placements occurred in 15 of 624 patients (2.4%); missed pneumothoraces occurred in 6 of 624 patients (<1%). Aggressive prehospital physician management of blunt chest trauma leads to an earlier treatment of potentially life-threatening injuries. Significant morbidity can be avoided by prompt pleural decompression using proper techniques.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Hypertonic saline resuscitation of patients with head injury: a prospective, randomized clinical trial.
Experimental and clinical work has suggested that hypertonic saline (HTS) would be better than lactated Ringer's solution (LRS) for the resuscitation of patients with head injuries. No clinical study has examined the effect of HTS infusion on intracranial pressure (ICP) and outcome in patients with head injuries. We hypothesized that HTS infusion would result in a lower ICP and fewer medical interventions to lower ICP compared with LRS. ⋯ As a group, HTS patients had more severe head injuries. HTS and LRS used with other therapies effectively controlled the ICP. The widely held conviction that sodium administration will lead to a sustained increase in ICP is not supported by this work.
