Randomized Controlled Trial Comparative Study Clinical Trial
Gastric mucosal pH and oxygen delivery and oxygen consumption indices in the assessment of adequacy of resuscitation after trauma: a prospective, randomized study.
To compare gastric mucosal pH (pHi) and global oxygen variables [Oxygen Delivery Index (DO2I) and Oxygen Consumption Index (VO2I)] as indicators of adequacy of resuscitation after major trauma. ⋯ pHi may be an important marker to assess the adequacy of resuscitation. pHi monitoring may provide early warning for systemic complications in the postresuscitation period.

Head injuries (HIs) remain a major contributor to trauma mortality, with many deaths occurring despite optimal use of available therapy. Injury prevention is vital to decrease the impact of HIs. Helmets can decrease the severity of HIs in both bicycle crashes (BCs) and motorcycle crashes (MCCs). ⋯ For MCCs, severe HIs declined from 20% before passage of the helmet law to 9% afterward (p < 0.001). Mortality decreased for BCs and MCCs (p < 0.05), and length of hospital stay and ICU stay decreased for BCs (p < 0.05). The percentage of helmeted BC admissions rose from 0% to 32% (p = 0.009), and helmeted MCC admissions rose from 41% to 80% (p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

Immune competence declines following major injury, and predisposes the trauma patient to infection. Interleukin-10 (IL-10), although an immunosuppressive cytokine, is also important in the initiation of immune responses. This study investigated alterations in IL-10 and immune function associated with polymicrobial sepsis following trauma using murine femur fracture (FFx) and cecal ligation/puncture (CLP) models. ⋯ Lymphocyte proliferative responses were significantly suppressed in FFx and CLP animals. Splenocyte IL-10 production was significantly reduced in FFx and CLP animals, with concurrent increases in nitrite and tumor necrosis factor release. This study documents that trauma induces alterations in the inflammatory cytokine cascade that affect the immune response to subsequent septic challenges.

Randomized Controlled Trial Clinical Trial
Maintenance of serum albumin levels in pediatric burn patients: a prospective, randomized trial.
A prospective, randomized trial was performed to determine whether maintaining serum albumin levels in burned pediatric patients had any effect on morbidity and mortality. Patients < 19 years of age with burns > 20% total body surface area were randomized to receive supplemental albumin to maintain levels 2.5 to 3.5 g/dL ("High Albumin") or were given albumin only if levels dropped < 1.5 g/dL ("Low Albumin") after completing burn shock resuscitation. The 36 patients in the Low Albumin group were well matched for age, burn size, depth of injury, and inhalation injury when compared with the High Albumin group (34 patients). ⋯ No differences in hematology, electrolytes, or nutritional laboratories were found. Finally, length of stay, complication rate, and mortality were not affected by albumin treatment. Albumin supplementation to maintain normal serum levels does not seem to be warranted in previously healthy children who suffer severe burns and who receive adequate nutrition.
