Implementation of a Massive Transfusion Protocol: Evaluation of Its Use and Efficacy.

Massive transfusion protocols (MTPs) allow practitioners to follow a prescribed algorithm for the rapid replacement of blood products during a massive hemorrhage. They function as an established protocol to provide consistent treatment. Once implemented, the MTP must be evaluated to ensure best practice. The purpose of this clinical improvement project was to formally evaluate the use and efficacy of an MTP during its first year of implementation. The specific aims were to (1) determine whether MTP activations were missed; (2) compare outcomes between those patients managed by the MTP and those who were not; and (3) provide recommendations to the institution's stakeholders. A retrospective medical record review was conducted with 101 electronic medical records of adult trauma patients treated over 1 year. Patients were identified to have experienced massive bleeding if their medical record contained 1 of 4 indicators: (1) transfusion of uncrossmatched blood; (2) tranexamic acid administration; (3) transfusion of 4 or more units of packed red blood cells (PRBCs) in 1 hr; and/or (4) transfusion of 10 or more units of PRBCs in 24 hr. While 58 patients experienced massive bleeding, only 16 (28%) were managed using the MTP. Although the non-MTP group received fewer transfused blood products due to higher initial and 24-hr hemoglobin levels, more deaths occurred in this group than in the MTP group. The recommendations were to (1) establish well-defined criteria for MTP activation based on the 4 indicators of massive bleeding and (2) regularly evaluate the use and efficacy of the MTP to ensure positive patient outcomes.

Thigh compartment syndrome in urban trauma: bullets to blame, not collisions.

BACKGROUND: Compartment syndrome of the thigh is a surgical emergency rarely reported in the literature. The most common etiologies include blunt trauma, vascular injuries from penetrating trauma, and hematoma formation. Thigh compartment syndrome (TCS) is important as it is often associated with concomitant severe injury with mortality rates as high as 47%. This study aims to identify mechanisms of injury, clinical presentation, and outcomes associated with TCS in the urban trauma patient population. METHODS: Demographic and clinical information for all patients with a diagnosis of TCS at a level 1 urban trauma center over a 10.5-y period were reviewed. Collected data included age, sex, mechanism of injury, method of diagnosis, time taken for diagnosis and management, methods of decompression, wound management, lengths of stay in the intensive care unit and hospital, amputation rate, and hospital disposition. RESULTS: Ten patients were identified with diagnosis of TCS. The mechanism of injury was penetrating in six patients and blunt in four. The mean time from injury to diagnosis was 23.4 h. Intensive care unit and hospital lengths of stay were significantly increased among patients sustaining penetrating injuries compared with blunt injuries. Two of the six penetrating injury patients underwent an amputation. Eight of 10 patients were ambulatory on discharge. There were no mortalities. CONCLUSIONS: Among urban trauma patients, penetrating injuries of the thigh and adjacent vascular structures and the need for decompressive fasciotomy of the lower leg are the major risk factors for TCS. Clinical diagnosis and early intervention with fasciotomy remain the mainstay of treatment.

Traumatic panhypopituitarism resulting in acute adrenal crisis.

Pituitary function plays an integral role in the physiologic response to traumatic injury. A significant proportion of trauma patients develop partial pituitary insufficiency. While isolated deficiencies of individual pituitary hormones are common, there are few reports in the literature of traumatic pan-pituitary failure with deficiency of all major pituitary hormones. We present a case of a patient involved in a motorcycle accident who sustained a sella turcica fracture, epidural hemorrhage, subdural hemorrhage, optic nerve palsy, and bilateral abducens nerve palsies. Three days after the accident, the patient became hypotensive and progressed to cardiopulmonary arrest. He was resuscitated and had spontaneous return of circulation. Despite adequate fluid resuscitation and vasopressor support, he remained profoundly hypotensive. Following administration of hydrocortisone, his blood pressures dramatically improved. He was found to have laboratory abnormalities, suggesting deficiencies of corticotropins, somatotropins, thyrotropins, gonadotropins, prolactin, and antidiuretic hormone. This is the first reported case of a patient with traumatic total panhypopituitarism complicated by acute adrenal crises during initial postinjury hospitalization. A review of the literature with comparison with other studies of trauma patients with deficiencies in five or more axes is presented. A high level of suspicion for central adrenal insufficiency and prompt administration of corticosteroids in the setting of symptomatic pituitary trauma can result in favorable outcomes. Screening for and treating posttraumatic hypopituitarism can result in improved rehabilitation and increased quality of life for trauma patients.
