Filter by:Abdominopelvic CT (CTap) utilization rose significantly in blunt trauma patients over the last decade. However, the observed increases failed to reduce mortality or missed injury rates. Several investigators have derived (citation) and validated (citation) clinical decision rules that attempt to identify a subset of low risk pediatric and adult patients in whom abdominopelvic CT imaging can be safely eliminated. Thus far these efforts failed to significantly reduce utilization. The investigators propose an alternative and complimentary strategy to decrease radiation by selectively eliminating the pelvic imaging portion of the abdominopelvic CT in low risk patients. In stable, alert patients without clinically evidence of pelvis or hip fractures, abdominal CT imaging alone (diaphragm to iliac crest) identifies clinically significant intra-abdominal injury (cs-IAI) as accurately as routine abdominopelvic imaging (diaphragm to greater trochanter) and results in a clinically important decrease in radiation exposure. The study will investigate this by comparing the accuracy of an imaging protocol using CT abdomen alone versus CT abdomen and pelvis to detect cs-IAI among stable, blunt trauma patients without suspected pelvis or hip fractures in two age groups: ages 3-17 years and 18-60. Patients will undergo CT imaging as deemed clinically indicated by the treating clinician. Among those who have abdominopelvic CT scans, the study will determine the test characteristics of CT abdomen alone versus CT abdomen plus CT pelvis imaging for the identification of cs-IAI. The reference standard will include initial radiology reports, with structured follow up of indeterminate scans, operative reports, and 7-day medical record review.
The research protocol aims to compare the utility of contrast enhanced abdominal sonography with computerized tomography in the evaluation of children with blunt abdominal trauma. Hemodynamically stable children ages 7-18 who are transferred to Children's Hospital on the trauma service with a CT scan of abdomen & pelvis already performed at the referring institution will be identified by the trauma service as eligible for inclusion. The ultrasounds will be performed by one of two Attending Radiologists involved in the study. The contrast being used for the study is Optison (GE Healthcare Inc, Princeton, NJ), which is an injectable suspension of Perflutren Protein-Type A Microspheres. This has been used in echocardiography as well as abdominal ultrasonography for evaluation of pediatric abdominal and pelvic solid tumors. The contrast enhanced ultrasound will be performed by radiologist. Contrast enhancement only lasts for 3-5 minutes per injection, therefore Optison will be redosed up to 2 additional doses for the completion of the ultrasound. Vital signs will be monitored for 30 minutes after the contrast agent is given and any adverse reactions will be recorded. Adverse reactions to Optison have occurred within this time frame in the literature. Subsequent medical care will be as indicated per the clinical practice guideline.
The purpose of this study is to explore acute hemodynamic and ventilatory responses to head-down 30 degree postural drainage position in patients with blunt chest and/or abdominal injury in the traumatic intensive care unit.
The major goal of this project is to conduct a randomized controlled trial studying an initial evaluation strategy with abdominal ultrasound versus a strategy without abdominal ultrasound for the evaluation of children with blunt abdominal trauma. The proposal's objectives are to compare the following variables in those that randomize to abdominal ultrasound versus those that do not: 1. rate of abdominal CT scanning 2. time to emergency department disposition 3. the rate of missed/delayed diagnosis of intra-abdominal injury 4. the costs.
Damage control laparotomy (DCL) is a life saving maneuver used with success in trauma and acute general surgery patients. The technique involves source control of sepsis and hemorrhage with an abbreviated laparotomy. In other words, the surgical procedure is cut short to allow for resuscitation in the ICU after the immediately life threatening pathology is treated. Planned re-exploration is then performed within 24-48 hours. It is at this procedure that the injuries are reconstructed. This technique, unfortunately, has several complications implicit with its use including wound infection, enterocutaneous fistula formation, and intra-abdominal abscess development.[1] Additionally, in patients whom primary fascial closure is not achieved, extensive abdominal wall reconstruction will be required in 6-12 months. The key for preventing these complications is definitive closure of the abdominal fascia, however, 10-50% of patients will have a planned ventral hernia with an open abdominal wound at dismissal [1,2] Proven methods for decreasing the rate of planned ventral hernia utilize tension in the midline to counter the effects of lateral abdominal muscular retraction.[3,4,5] Despite these improvements, however, the planned ventral hernia rate continues to be substantial.[2] Botulinum toxin a (BTX) is an FDA approved neuron modulating agent which has been used extensively in cosmetic, motor and pain disorders over the past 20 years [6,7]. The toxin blocks acetylcholine and pain modulator release (calcitonin gene related peptide and substance P) from the pre-synaptic cholinergic nerve terminal. The peptides are unable to bind at their motor end plate receptors through a process that cleaves proteins involved in the transport protein cascade. This results in flaccid paralysis and neuromodulation of the abdominal wall muscles resulting in reduced lateral tension and pain. Theoretically, this could increase the rates of primary fascial closure, improve pain sensation, decrease the rate of complications associated with open abdomens all while lowering the costs and need for future abdominal wall reconstruction.
The objective of this prospective study is to evaluate short-term, mid-term, and long-term clinical outcomes associated with the use of Permacol™ Biological Implant in the treatment of complex abdominal wall defects
Abdominal penetrating trauma represents a frequent cause of consult into emergency rooms in Venezuela. Accidents and violence at Hospital "Miguel Perez Carreño" along april 2009 were represented by gunshots and stabbing wounds which 8th. and 18th cause for medical attention respectively within a total of 76 cases. Likewise gunshot wounds reach the first cause of morbility into general surgery services with 21 cases and the stabbing wounds the 12th cause with 12 cases within the same period. Early therapy is defined as the antibiotic dose administrated within the first 12 hours after the trauma. Abdominal cavity contamination by micro-organism is not synonymous of stablished infection, the extension of contamination and intensity of reaction should be enough in order to allow the inflammatory focus developing. Abdominal cavity needs at least 12 - 24 hours of exposure to the infectious material to allow the stablishment of such infection. Origin and amount of contaminant material influence the size of inoculated bacteria and the speed that infection develops. There is not an absolute criteria to determine when intrabdominal contamination progress to an established infection. Surgeons decides the must adequated therapy according to clinical history, radiology tests and findings during surgery. Selected patients for early antibiotic therapy in penetrating abdominal trauma includes those with traumatic intestinal wounds with less than 12 hours of evolution and those with gastroduodenal wounds lesser than 24 hours as well. There are different antibiotics indicated for intrabdominal infections. Ertapenem is a low resistance carbapenem with a broad spectrum into microbial flora presenting in penetrating abdominal trauma. Its media life and blood therapeutic levels allows the use of an unique dose within the first 24 hours of trauma. This research protocol has been designed according to established patterns for clinical investigation and our goal is to achieve criteria in decision making about antibiotic administration in patients with penetrating abdominal trauma and evaluate the security of an Early short term antibiotic therapy with Ertapenem 3 days vs 7 days, decreasing hospital costs related to indiscriminate use of antibiotics.
Retrospective study in order to investigate the outcome after conservative (with or without transcatheter arterial embolization) and surgical treatment of splenic injuries.
The role of teleradiology has far reaching implications for the health of remote and underserved populations. The ability to coordinate radiographic evaluation and diagnosis from a distance has the potential to raise the standard of patient care throughout the world. Perhaps the safest and most cost effective mode of teleradiology today is telesonography. The current project attempts to determine the extent that telesonography improves the standard of care within a rural government-run primary clinic within the Dominican Republic. The work reported herein is intended to compare the use of telesonography to the current standard of sonographic examination (referral to government hospital 60km from target clinic). The study was conducted by randomly assigning 100 patients with clinical indications for sonographic examination into experimental and control groups. Following a 60-day implementation period, the following research questions will be addressed: 1) To what extent does the use of asynchronous telesonography increase the percentage of definitive diagnoses based on the total number of scans (definitive diagnoses / total number of scans)? 2) To what extent does the use of asynchronous telesonography increase the continuity of care for patients? 3) To what extent does the elapsed time between scanning and final radiological interpretation decrease with the use of asynchronous telesonography? This study will also look at the history of telemedicine / telesonography and its dissemination into the mainstream practice of medicine, explore training protocols that may be used to assist others to establish new telesonography programs in a developing nations, and discuss both advances and persistent barriers to the implementation of telesonography programs. Hypothesis: The use of a store-and-forward telesonography system in this setting will increase the speed and number of final diagnoses per scan received by the target clinic and will increase the continuity of care by increasing the number and speed of follow-up appointments to the target clinic.
The aim of this study is to establish the additional effectiveness and costs of routine thoraco-abdominal computed tomography (CT) in blunt trauma patients versus conventional radiological imaging and to determine which clinical parameters predict a high additional value of routine thoraco-abdominal CT.
