Postinjury multiple organ failure (MOF) remains the leading cause of morbidity and late mortality after severe trauma. Our previous work consistently identified an association between thrombocytopenia and progression to MOF. In addition, recent studies suggest that platelets play a critical role in postinjury hyperinflammation. Therefore, we hypothesized that postinjury thrombocytopenia is a marker for progression to MOF. ⋯ Early postinjury thrombocytopenia is an independent risk factor for MOF, death, and other complications. Following platelet count dynamics over the first several days postinjury can help predict which high-risk patient will develop these adverse outcomes.

Cervical spine (CS) clearance in obtunded blunt trauma patients (OBTPs) remains controversial. When computed tomography (CT) of the CS is negative for injury, debate continues over the role of magnetic resonance imaging (MRI). Use of MRI in OBTPs is costly, time-consuming, and potentially dangerous. Our study evaluated the safety of a protocol to discontinue the cervical collar in OBTPs based on CT scan alone. ⋯ Removal of CS precautions in OBTPs with gross movement of all extremities is safe and efficacious if CT CS is negative for injury. Supplemental MRI CS is not needed in this patient population.

Computed tomography (CT) has a high sensitivity and specificity for detecting abdominal injuries. Expeditious abdominal imaging in "quasi-stable" patients may prevent negative laparotomy. However, the significance of potential delay to laparotomy secondary to abdominal imaging remains unknown. We sought to analyze whether the use of abdominal CT (ABD CT) in patients with abdominal injury requiring laparotomy results in a significant delay and a higher risk of poor outcome. ⋯ Delay secondary to abdominal imaging in patients who require operative intervention results in an independent higher risk of mortality. ABD CT imaging is an important and useful tool after injury; however, these results suggest that delay caused by overreliance on ABD CT may result in poor outcome in specific patients. Clinicians who take care of critically injured patients should be aware of and understand these potential risks.

Management of intra-abdominal hypertension with an open abdomen and planned ventral hernia results in decreased mortality. But, delayed abdominal wall reconstruction (DAWR) is necessary. Results after DAWR demonstrate acceptable recurrence, morbidity, and mortality rates. However, little is known about quality of life (QOL) after DAWR. The purpose of this study was to analyze QOL after DAWR. ⋯ Patients who undergo DAWR have decreased physical functioning and have a high prevalence of PTSD and depression. Consideration should be given to screening for depression and PTSD in this patient population.

The amount of imaging studies performed for disease diagnosis has been rapidly increasing. We examined the amount of radiation exposure that pediatric trauma patients receive because they are an at-risk population. Our hypothesis was that pediatric trauma patients are exposed to high levels of radiation during a single hospital visit. ⋯ When the use of radiologic imaging is considered essential, cumulative radiation exposure can be high. In young children with relatively long life spans, the benefit of each imaging study and the cumulative radiation dose should be weighed against the long-term risks of increased exposure.
