To evaluate alterations in renal blood flow in sepsis-induced renal failure, we developed and studied a percutaneously placed thermodilution renal blood flow catheter in eight critically ill patients. Para-aminohippurate extraction coefficients were decreased, supporting the need for renal vein sampling to determine CPAH in sepsis. Thermodilution and CPAH(More)
OBJECTIVES a) To define the frequency of dangerous (intracardiac) central venous catheter placement in a multicenter study of large community hospital intensive care units (ICUs) and to evaluate physician responses to this finding. b) To validate right atrial electrocardiography as a technique to assure adherence with recent Food and Drug Administration(More)
STUDY OBJECTIVE To compare conventional versus ultrasound-guided internal jugular vein cannulation techniques. DESIGN Patients were randomly assigned to receive either conventional or two-dimensional ultrasound-guided internal jugular vein cannulation. Patients who could not be cannulated with five or fewer passes by either technique, were crossed over to(More)
Herpes simplex virus type 1 glycoproteins gE and gI form receptors for the Fc domain of immunoglobulin G (IgG) which are expressed on the surface of infected cells and on the virion envelope and which protect the virus from immune attack. Glycoprotein gE-1 is a low-affinity Fc receptor (FcR) that binds IgG aggregates, while gE-1 and gI-1 form a complex(More)
We sought to define variations in internal jugular vein (IJV) anatomy and the effect of recommended cannulation maneuvers on a population of ICU patients. Maneuvers that decreased IJV lumen cross-sectional area were carotid artery palpation (1.48 to 0.82 cm2, p less than .05) and advancement of the needle (1.57 to 0.75 cm2, p less than .001). The head-down(More)
BACKGROUND/AIMS The inability to precisely measure the area of Barrett's metaplasia has impaired the study of its natural history and response to therapy. This study used a novel computer program that creates two-dimensional maps of the esophagus allowing for calculation of the area of Barrett's metaplasia. METHODS Endoscopic photographs of Barrett's(More)
Intramuscular (im) pentamidine isethionate can cause substantial local pain and inflammation at the injection site. This drug is being used more frequently in recent years to treat Pneumocystis pneumonia, particularly in patients with acquired immunodeficiency syndrome. Clinicians began administering it iv despite warnings that iv administration might cause(More)
Kapadia et al [1] are to be congratulated for alerting the clinician to the serious vascular complications that can arise from central venous catheterization. They aptly illustrate the morbidity associated with catheter placement and the importance o f chest roentgenograms to confirm the final position of the catheter tip. However, even though chest(More)
