Penetrating and blunt abdominal trauma

This article is an overview of abdominal trauma relating to both penetrating and blunt mechanisms of injury. The incidence of abdominal injuries is discussed. Illustrated through case studies are interventions and treatment applicable to nursing practice. General principles of abdominal assessment are included. Anatomy and physiology of the different organ systems, as well as complications, is briefly overviewed. Differences between solid and hollow organs are reviewed. Pearls and pitfalls that impact nursing practice are presented for specific injuries.     

Penetrating orbital trauma

A small number of patients suffer penetrating injury to the orbit in the absence of trauma to the globe. Hospital records from the Jules Stein Eye Institute and affiliated hospitals were reviewed to obtain such cases. Five cases of penetrating orbital trauma, in which the globe was spared, are discussed. Many of the injuries initially appeared trivial but subsequent complications were severe. A review of these cases suggests that the shape and speed of the penetrating object, the anatomical location of the entry wound, and the physical characteristics of intraorbital structures determine the character and severity of orbital injuries.     

Penetrating trauma to the buttock

Penetrating trauma to the buttock is an injury with potential impact on multiple body systems. The purpose of this study was to review our experience with penetrating trauma to the buttock, to establish the frequency of system injury and related morbidity and mortality, and to make recommendations for the evaluation and management of these injuries. Among the 56 system injuries, soft tissue injuries predominated. Of the 25 operative procedures done, eight were for wound care and debridement and seven for rectal injuries; three were orthopedic, two vascular, three genitourinary, and one neurosurgical. One patient had examination under anesthesia, and one had laparotomy for missile trajectory. There were no deaths in this series. Morbidity consisted of nerve injury/defect in three patients, stroke in one patient, and impotence in one. An understanding of the systems at risk in penetrating buttock trauma is necessary for prompt multisystem work-up.     

Penetrating trauma to the extremity

Penetrating trauma to the extremities is a complex disease that foremost requires the evaluation for vascular injury. This monograph will address an algorithm to assess for associated vascular injury that includes current evaluation techniques. Approaches to wound management and use of antibiotics in the ED are also addressed.     

Penetrating trauma to the head

Penetrating trauma to the brain is not as common as blunt trauma; however, the incidence is becoming a frequent occurrence in our society. Rapid transport to trauma centers where definitive care can be rendered is essential. Outcome depends on the site of the missile tract, the presenting neurologic status, and the extent of neurologic tissue destruction. Neurologic deterioration occurs rapidly, and outcome results seem to depend on the patient's neurologic status at the time of surgery. CT scanning is the diagnostic procedure of choice and should be performed if the patient's condition is stable (see Fig. 3). Aggressive removal of missile and bone fragments needs to be balanced by the knowledge that it is preferable to leave behind a few hard-to-reach fragments than to increase the patient's neurologic deficit. CT scanning in the postoperative period is very helpful in identifying abscess formation as well as new or recurrent hematomas, edema, and areas of tissue injury not evident at the time of initial scanning. Antibiotic therapy should be initiated preoperatively. Control of elevated ICP plays a significant role in decreasing mortality and morbidity. Judicious debridement of injured brain combined with medical management of increased ICP will maximize the quality of recovery and increase survivability. Although great strides have been made in reducing mortality and morbidity for trauma patients, the sad issue is that the majority of traumas are preventable. Until society is willing to understand that it needs to make firearm safety a priority, there will always be patients to care for who have sustained a penetrating injury.     

Blunt abdominal trauma

Blunt abdominal trauma results in potentially life-threatening injuries that require organized rapid evaluation and treatment. Resuscitation of hemodynamically unstable patients should be completed in the operating room if retroperitoneal hemorrhage is not strongly suspected. DPL and abdominal CT scans are methods of studying the injured abdomen, and each has advantages and disadvantages. The clinician must choose the appropriate study based on the clinical question raised by each patient. Repeated frequent physical examinations and serial laboratory tests are essential to exclude a missed injury. Deterioration of hemodynamic status or abdominal examination are indications for urgent laparotomy regardless of the initial diagnostic impressions.     

Penetrating facial trauma: a management plan

Penetrating wounds of the face present a spectrum of injuries and multiple management dilemmas. The surgeon's first concern remains the establishment of a proper airway and control of life-threatening injuries. Selected ancillary diagnostic procedures should be used to confirm vascular, aerodigestive, or central nervous system injuries. Diagnosis of injuries may require arteriography, endoscopic examination, barium studies, computerized tomography, and detailed ophthalmologic examination. We review 16 cases of penetrating facial trauma treated at the University of South Alabama Trauma Center over a one-year period. The injuries resulted from 13 gunshot wounds and three stab wounds. Injuries of the central nervous system occurred in three patients, mandibular fractures in four, optic nerve or globe injury in three, and maxillary sinus fracture in seven. Our experience with these patients demonstrates the spectrum of injuries and serves as a basis for a management algorithm.     

Advances in abdominal trauma

Emergency practitioners routinely encounter patients who suffer from abdominal trauma, be it blunt or penetrating. These injuries are often confounded by altered mental status, distracting injuries, or lack of historical information, and may present challenges in management. However, in the last several years new approaches to the diagnosis and management of abdominal trauma, including bedside ultrasound, newer generation computed tomography scans, laparoscopy, and the ability for selected nonoperative management expedite identification of life threatening injury and offer new options in treatment.     

Ultrasound in abdominal trauma

This article reviews current issues regarding the Focused Assessment with Sonography for Trauma (FAST) examination. Technical performance issues, decision-making and practice algorithms, fluid volume and scoring systems, proficiency and training, and the role of the FAST in pediatric trauma are covered. This article examines the FAST examination from a practical, evidenced-based stand-point.     

Blunt abdominal trauma.

Blunt abdominal trauma is a possible sequel of many accidents and can result in death from hemorrhage or sepsis if it is not detected early and managed aggressively. A thorough history of the causative accident, a systematic abdominal examination, selected laboratory studies, and x-ray films are helpful in establishing the diagnosis. Peritoneal lavage is, however, the most reliable assessment tool (besides an exploratory laparotomy) for confirming significant viscus injury and intra-abdominal hemorrhage. Nurses who are assisting in the evaluation of trauma victims should be thoroughly familiar with the mechanics responsible for blunt abdominal injury, the initial steps for stabilizing the victim, and the usual tests and procedures that aid in diagnosis.
