A novel use of the endocavity (transvaginal) ultrasound probe: central venous access in the ED.
Use of ultrasound (US) to obtain intravenous access is usually accomplished with a 7.5-MHz linear US probe. This paper describes the use of an endocavity US probe to obtain vascular access. Since both probes use US of the same megahertz values, the picture quality with the two is no different. Because the equipment used for each type of probe costs thousands of dollars, the economic value of having to purchase one less probe may be significant.

Eclampsia is defined by the occurrence of seizures resulting from hypertensive encephalopathy on the background of preeclampsia. The development of hypertension during pregnancy, a serious and potentially fatal condition, is a leading cause of maternal and fetal morbidity and death in the United States.(1-3) It is a disease with preventable complications. The pathophysiology of hypertension during pregnancy is unclear, but there is consensus that aggressive treatment is warranted to prevent complications to both fetus and mother. A current concept of pathophysiological character, diagnosis, prevention, and management of eclampsia is discussed.
