Clinical Trial
Post-traumatic hypotension: should systolic blood pressure of 90-109 mmHg be included?
It is generally accepted that patients with a systolic blood pressure (SBP)<90 mmHg are in "shock" and have a worse prognosis than patients with a higher SBP. Our objective was to determine if patients with a SBP of 90-109 mmHg have a worse outcome than patients with a higher SBP following trauma. Patients with gastric, small bowel, and/or diaphragm injuries were identified retrospectively through the trauma database from 1980-2003. ⋯ Trauma patients with a systolic blood pressure of 109 mmHg or below are at increased risk for morbidity and mortality following trauma. Patients with a systolic blood pressure of 90-109 mmHg following trauma should be considered as a special group requiring aggressive resuscitation and surgery. Early operative control of hemorrhage in these patients can reduce mortality and infection.

Comparative Study Clinical Trial
Influence of sex and age on mods and cytokines after multiple injuries.
Although salutary effects of female sex steroids have been demonstrated not only in proestrus females but also in male animals treated with estradiol in different models of trauma, it remains unknown whether sex hormones influence post-traumatic immune response in humans. We therefore investigated the effect of sex and age on organ dysfunction and clinical course in patients with multiple injuries. Polytraumatized patients (injury severity score>16) between 16 and 65 years old admitted to the Hannover Medical School Level 1 trauma center between January 1997 and December 2001 were included. ⋯ Thus, in this prospective study, sex difference was confirmed in MODS and sepsis, with a benefit observed in females. Although the levels of sex steroids were not measured, it seems that the protective effects may be due to estrogen effects on plasma cytokines. This suggestion is based on the fact that such salutary effects were apparent predominantly in premenopausal females.
