We determined whether factors present soon after burn predict which patients will receive more than 4 mL/kg/% burn during the first 24 hours, and whether total fluid intake during the first 24 hours (VOL) contributes to in-hospital mortality (MORT). ⋯ Burn size and weight (negatively) were associated with greater VOL. However, a close linear relationship between burn size and VOL was not observed. Mechanical ventilation supplanted TBSA by 24 hours as a predictor of high VOL. Worst base deficit, TBSA, and an age function, but not VOL, were predictors of MORT.

Hepatocyte growth factor (HGF) has a significant effect on the regeneration of epithelial and endothelial cells. Studies have also shown an important role of HGF in wound healing and organ regeneration. Because recent studies indicate that polymorphonuclear leukocytes (PMNLs) store HGF in their specific granules and that HGF can be degranulated in the inflammatory tissue in which activated PMNLs migrate, we evaluated the storage and release of HGF in PMNLs from patients with systemic inflammatory response syndrome (SIRS) and attempted to examine the role of HGF from PMNLs in the systemic inflammatory process. ⋯ Activated PMNLs in SIRS patients increased HGF in their granules and demonstrate enhanced degranulation of HGF. The release of HGF from migrated PMNLs in the inflammatory tissue may play an important role in wound healing and organ regeneration under those conditions.

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.
