4 Clinical Trials for Various Conditions
The purpose of this study is to compare success rates of antegrade and retrograde intravenous (IV) catheters in their ability to aspirate 20 milliliter blood sample within a 2 minute time frame, 3 hours after initial insertion. Antegrade IV catheters are placed identically to conventional IV catheters, with the end of the catheter pointed toward the direction of blood flow to the heart. Retrograde catheters are placed "backwards" with the end of the catheter pointed away from the direction of venous blood flow. The hypothesis is that retrograde IVs will have a significantly higher success rate of blood draw at the 3 hour time mark without use of a proximal tourniquet.
Phase I * determine the location of the peripherally inserted central catheter (PICC) tip upon observation of maximum p-wave amplitude Phase II * determine the precision of PICC placement in the Sherlock 3CG group versus the standard PICC placement
The purpose of this study is to observe and analyze variation of diastolic blood pressure measurements at third trimester of pregnancy and when they present for delivery in comparison to healthy volunteers. When patients present for delivery, we expect blood pressure to be lower than normal. However this is not the case. We aim to determine where this trend occurs throughout to duration of pregnancy, and propose possible explanation as to the source of this event. After discharge, the information recorded includes each patient's blood pressure upon admission to the labor floor, and several blood pressure measurements from prior clinical visits.
The purpose of this study is to determine whether or not a new brain function monitor can distinguish between anesthetized and awake patients. The device implemented utilizes functional near-infrared (fNIR) technology to detect anesthesia depth as well as reaction to stimuli during surgical procedure. After obtaining consent the device is placed across the forehead of the patient. A baseline signal is obtained prior to induction. The fNIR signal is continuously recorded throughout the procedure. Key events as well as administration of drug are recorded in order to observe changes in the signal trend. Neither the device nor the light emitted is hazardous to the patient - no risks or discomforts are involved.
