Randomized Controlled Trial Clinical TrialFemoral deep vein thrombosis associated with central venous catheterization: results from a prospective, randomized trial.
To determine the frequency of central venous catheter-induced deep vein thrombosis of the femoral vein. ⋯ Based on the data from this study, we concluded that femoral vein catheterization is associated with a 25% frequency of lower extremity deep vein thrombosis compared with similar patients receiving subclavian or internal jugular vein catheters. The femoral vein remains an important emergency venous access route. Physicians inserting femoral vein catheters should be aware of the risk of lower extremity deep vein thrombosis and should consider performing lower extremity duplex ultrasound examinations on removal of femoral vein catheters.

Randomized Controlled Trial Clinical TrialPretreatment of normal humans with monophosphoryl lipid A induces tolerance to endotoxin: a prospective, double-blind, randomized, controlled trial.
Endotoxin is one of the principal mediators of Gram-negative septic shock. Pretreatment with monophosphoryl lipid A, a hydrolyzed derivative of endotoxin from Salmonella minnesota R595, induces endotoxin tolerance and nonspecific resistance to infection in experimental animals. The present clinical trial was undertaken to test the response to monophosphoryl lipid A in humans and the ability of monophosphoryl lipid A to attenuate the response of normal human volunteers to U.S. Reference Ec-5 endotoxin. ⋯ Data indicate that monophosphoryl lipid A, in a dose 10,000 times that of endotoxin, used in experimental pyrogenicity trials, is well tolerated in human volunteers. Pretreatment of normal human volunteers with monophosphoryl lipid A attenuated the systemic response to bacterial endotoxin. These data support further clinical testing of monophosphoryl lipid A for the prevention or amelioration of the severe sequelae of sepsis.

Randomized Controlled Trial Multicenter Study Clinical TrialFacilitation of internal jugular venous cannulation using an audio-guided Doppler ultrasound vascular access device: results from a prospective, dual-center, randomized, crossover clinical study.
To determine the utility of an audio-guided Doppler ultrasound device in improving success and decreasing complications in cannulation of the internal jugular vein in high-risk patients. ⋯ The use of an audio-guided Doppler ultrasound vascular access device was associated with increased success of cannulation and a decreased frequency of significant complications in a population of high-risk patients with obesity or coagulopathy.
