Filter by:Pelvic fracture is a usual injury in trauma patients. An unstable trauma patient with a pelvic fracture has an elevated risk of death due to pelvic bleeding and the associated injuries. Traditionally, it has been estimated that the main source of bleeding is venous and, consequently, the main treatment has been the preperitoneal pelvic packing. Nevertheless, according to new data, arterial bleeding appears to be a more important source of pelvic bleeding than it was thought and angioembolization seems to be a good alternative in the treatment of these injuries. Consequently, it is important to define better the management of these patients. This investigation project consists in a clinical trial study, performed by a multidisciplinary team of many hospitals around the country, in which angioembolization and preperitoneal pelvic packing are compared. Unstable trauma patients with a pelvic fracture and no other injuries (negative FAST / peritoneal aspiration, no evidence of bone fractures or thoracic injuries) will be submitted, in less than 60 minutes from hospital arrival, to angioembolization or preperitoneal pelvic packing, according to randomization. There will be a specific timing evaluation of different markers: hemodynamic (vital signs at arrival, immediately and 24 hours after treatment) and analytic (at arrival and upon entering to the Intensive Care Unit). Registered variables include: blood cell transfusions, vasoactive drug requirements, time elapsed between hospital admission and intervention, treatment duration, need of other strategies to stop pelvic bleeding, complications and mortality. The objective of this study is to determinate if angioembolization is superior to preperitoneal pelvic packing for pelvic bleeding control in unstable trauma patients due to pelvic bleeding.
A randomized controlled clinical trial. 24 adult ICU patients will be recruited upon decision to administer fluid bolus of 500ml of crystalloid. The fluid will then be randomized to be infused at controlled room temperature or warmed to body temperature. Hemodynamic measurements will be made for 2 hours following the bolus, and laboratory values will be noted. The hypothesis is that part of the hemodynamic response will differed in response to cooling, and be larger in the cold group.
The objective of this study is to use local topical anesthesia to numb the sensory input, captured by branches of the Trigeminal nerve found on the skin in and around the eye, to decrease a hemodynamic reflex seen during placement of a catheter for intra-arterial chemotherapy (IAC) for eye tumors in children. This Trigeminal-cardiac reflex brings about hemodynamic instability during general anesthesia. Normally, one could block this sensorial input with ophthalmic peribulbar placement of local anesthetics, but these eyes have malignant growth and invasive procedures may cause more harm. The investigators are aiming to numb the sensory branches of the trigeminal nerve non-invasively and observe for any decrease in these events.
