The microintroducer approach to obtaining initial venous access and threading a peripherally inserted central catheter (PICC) with and without imaging support is described. Equipment needed and steps to complete the procedure are described. Initial patient assessment and problem solving are discussed, as is application of the microintroducer technique in clinical practice. Potential complications and challenges are included.

The theory of hematopoiesis has been in existence for many years, providing the foundation for understanding the blood system and its development, and adding to the basic principles in the study of human development. As we enter the new millennium, we are able to use this groundwork of the hematopoietic system to further our research endeavors. It has provided the medical arena with the capability to expand and enhance treatment options for patients, and to explore further the vast possibility this system has to offer us beyond the year 2000.

Comparative Study Clinical Trial
Effect of two different short peripheral catheter materials on phlebitis development.
One of the most common causes of phlebitis in hospitalized patients is intravenous catheters. The material of the catheter is a determining factor in the development of phlebitis, as are factors such as age, gender, and medical diagnosis of the patient. The aim of this study, conducted in the coronary care unit of a 384-bed hospital in Ankara, Turkey, was to determine the effect of two different short peripheral catheters on phlebitis development caused by i.v. treatment. ⋯ The total phlebitis rate was 36.8%, with almost half of the patients (49.2%) in the Teflon catheter group and 24.0% of patients in the Vialon catheter group. A significant statistical relationship was found between phlebitis rate and variables such as gender, catheter material, and indwelling time. The results of the study demonstrate that Vialon catheters are associated with less risk of catheter-induced phlebitis than are Teflon catheters.

Injuries are the third leading cause of death in the United States, exceeded only by heart disease and cancer. The success of resuscitation after an acute injury is dependent on providing adequate oxygenation, restoring intravascular fluid volume, and maintaining optimum cardiac output and cellular perfusion. ⋯ Care of the trauma patient is a dynamic process and requires ongoing evaluation of clinical parameters. Fluid resuscitation is a central component in the overall management of the trauma patient.

A retrospective study of 431 patients who had peripherally inserted midclavicular or central catheters placed during a consecutive 13-month period using the conventional landmark method for placement was compared with a second group of 326 patients, who during a 12-month period had such catheters placed using ultrasonography. The data demonstrate a 42% decrease in the number of needle penetrations needed to successfully cannulate veins when ultrasound was used during placement. There is a 26% greater chance of successful cannulation of the vein on the first attempt with ultrasound-guided placements than with those using the traditional landmark method.
