Increased utilization of computed tomography (CT) scans for evaluation of blunt trauma patients has resulted in increased doses of radiation to patients. Radiation dose is relatively amplified in children secondary to body size, and children are more susceptible to long-term carcinogenic effects of radiation. Our aim was to measure radiation dose received in pediatric blunt trauma patients during initial CT evaluation and to determine whether doses exceed doses historically correlated with an increased risk of thyroid cancer. ⋯ Thyroid doses in 71% of study patients fell within the dose range historically correlated with an increased risk of thyroid cancer and whole body effective doses fell within the range of historical doses correlated with an increased risk of all solid cancers and leukemia. Selective scanning of body areas as compared with whole body scanning results in a statistically significant decrease in all doses.

"Failure to rescue" patients with complications is a factor contributing to high mortality rates after elective surgery. In trauma, where early deaths are the primary contributors to a trauma center's mortality rate, the rescue of patients with complications might not be related to overall trauma center mortality. We assessed the extent to which trauma center mortality was reflected by the center's ability to rescue patients with major complications. ⋯ Unlike reports from elective surgery, complication rates after severe injury differ across centers and parallel mortality rates. Centers with low overall mortality are more successful at rescuing patients who experience complications. A lower risk of complications and better care of those with complications are both at play in high-performing trauma centers.

Sepsis is increasing in hospitalized patients. Our purpose is to describe its current epidemiology in a general surgery (GS) intensive care unit (ICU) where patients are routinely screened and aggressively treated for sepsis by an established protocol. ⋯ In general surgery ICU patients, sepsis is predominantly caused by intra-abdominal infection. Multiple BODs are present in severe sepsis and septic shock but are notably advanced in septic shock. Despite aggressive sepsis screening and treatment, septic shock remains a morbid condition.

Data on intracranial pressure (ICP) and cerebral perfusion pressure (CPP) guide therapy in severe traumatic brain injury (TBI), but current linear analytic methods are insufficiently sensitive and specific for prognosis in dynamic situations over time. ⋯ Calculation of a BTI from continuous digital data predicts outcome in severe TBI and has potential for the design of real-time bedside early warning systems.

Brain tissue oxygenation (PbtO2)-guided management facilitates treatment of reduced PbtO2 episodes potentially conferring survival and outcome advantages in severe traumatic brain injury (TBI). To date, the nature and effectiveness of commonly used interventions in correcting compromised PbtO2 in TBI remains unclear. We sought to identify the most common interventions used in episodes of compromised PbtO2 and to analyze which were effective. ⋯ Clinicians use a limited number of interventions when correcting compromised PbtO2. Using strategies employing many interventions administered closely together may be less effective in correcting PbO2, ICP, and CPP deficits. Some PbtO2 deficits may be self-limited.
