To describe the simultaneous responses of systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial blood pressure (MAP), heart rate (HR), shock index (SI = HR/SBP), central venous oxyhemoglobin saturation (ScvO2), and arterial blood lactate concentration (Lact) to resuscitation of critically ill patients in the emergency department (ED), an observational descriptive study was conducted in the ED of an urban teaching hospital. Thirty- six patients admitted from the ED to the medical intensive care unit were studied. Vital signs were measured immediately on arrival to the ED (phase 1). ⋯ It was concluded that additional therapy is required in the majority of critically ill patients to restore adequate systemic oxygenation after initial resuscitation and hemodynamic stabilization in the ED. Additional therapy to increase ScvO2 and decrease Lact may not produce substantial responses in SBP, DBP, MAP, HR, and SI. The measurement of ScvO2 and Lact can be utilized to guide this phase of additional therapy in the ED.

In suburban and rural counties, patient transport to specialized facilities such as trauma centers may result in prolonged transport times with the resultant loss of ambulance coverage in the primary service area. We evaluated the American College of Surgeons trauma triage criteria as modified by New York State to determine the ability of these criteria to predict the need for trauma center care in victims of blunt traumatic injury. Blunt trauma patients were retrospectively identified through review of patient care reports for the presence either of mechanism or of physiological criteria for transport to a trauma center. ⋯ Patients with physiologic criteria may benefit from transport directly to a trauma center. Because of the low need for operative intervention and ICU services, patients with no criteria or mechanism criteria at long distances from a trauma center may be initially evaluated at the closest hospital and transferred to a trauma center if hospitalization or ICU care is necessary. Further study to determine the predictive value of certain individual mechanism criteria is warranted.

To determine if there is any effect of the full moon on emergency department (ED) patient volume, ambulance runs, admissions, or admissions to a monitored unit, a retrospective analysis of the hospital electronic records of all patients seen in an ED during a 4-year period was conducted in an ED of a suburban community hospital. A full moon occurred 49 times during the study period. ⋯ No significant differences were found in total patient visits, ambulance runs, admissions to the hospital, or admissions to a monitored unit on days of the full moon. The occurrence of a full moon has no effect on ED patient volume, ambulance runs, admissions, or admissions to a monitored unit.

Blunt traumatic rupture of the left ventricle of the heart is rarely diagnosed preoperatively and is usually fatal, with only a few survivors reported in the literature. This report describes a case of a 54-year-old woman who survived a left ventricular rupture from a motor vehicle accident. Her cardiac injury was not suspected because she was not hypotensive and had no signs of pericardial tamponade. She developed circulatory arrest 2 hours after her injury, during induction of anesthesia.
