Filter by:The purpose of this study is the comparison of the cardiovascular effects of remifentanil and nitroprusside for controlled hypotension
This study will provide capnography monitoring during routine upper endoscopy and colonoscopy with moderate sedation in order to see if it improves safety.
As kidney function declines, the ability to maintain water balance is impaired and is most often treated with hemodialysis. The removal of excess water in hemodialysis often leads to a sudden drop of blood pressure and causes symptoms of dizziness, light-headedness, cramping, and chest pain. This sudden drop in blood pressure has been linked with complications of heart attacks, strokes and even death. Research has focused on different ways to prevent dangerous drops in blood pressure during hemodialysis. One way is the use of blood volume monitoring biofeedback technology to monitor the patient's relative blood volume and automatically reduce the amount of fluid that is being removed when the blood volume is low to prevent the drop in blood pressure from occurring. This type of biofeedback device is currently available on some hemodialysis machines and while this approach appealing, it is not clear how effective this form of biofeedback is in preventing the drops in blood pressure. We plan to determine if the use of biofeedback based on the changes in the patient's blood volume will reduce the number of sudden drops in blood pressure that occur during hemodialysis. To do this, we will compare patients treated with this technology to current hemodialysis practices and follow them for important adverse outcomes. The result of interest will be the frequency of hemodialysis sessions complicated by a sudden symptomatic drop in blood pressure. We also plan to monitor the amount of water in the different body compartments, blood pressure, blood pressure medication use, markers of heart function, and patient symptoms and quality of life. We hope that by providing information on this technology we can reduce the sudden drops in blood pressure in hemodialysis, the associated rates of serious disease or death, and improve patient quality of life.
The purpose of the present study is to determine whether the use of an abdominal binder is effective in the non-pharmacological management of orthostatic hypotension in patients suffering from Parkinson's disease
The hypothesis is that plethysmography variability index can predict the occurrence of hypotension after spinal anesthesia for cesarean delivery
It is very important to decrease the bleeding during functional endoscopic sinus surgery (FESS) in order to increase the visibility of the surgical site. Our primary goal was to investigate the effects of magnesium sulfate and dexmedetomidine used for controlled hypotension on visibility of surgical site.
The primary purpose of this investigation is to validate the performance and safety of the Investigational Device (ID) against a validated and legally cleared device for measuring Blood Pressure (BP). The secondary purpose is to validate the performance of the ID over a period of 24 hours against a validated and legally cleared device for Ambulatory Blood Pressure Monitoring (ABPM).
In second trimester abortion above 22 weeks the investigators usually inject intra-cardiac Kcl for feticide. Digoxin intra-amniotic injection has been described in the literature in doses of 1-1.5 mg. with a success rate of about 80%, and up to 24 weeks. Our aim in this study is to investigate the safety and success rate of 1.5-2 mg. digoxin, intra-amniotic up to 30 weeks pregnancy .
Fluid challenge is often carried out in critical ill patients. Its responsiveness usually requires invasive monitoring. To use non-invasive methods is very tempting. We hypothesize that transcutaneous pO2,transcutaneous pCO2 and Central Venous pO2 variations provide feasible estimation on fluid responsiveness in critical ill patients.
The purpose of this study is to compare the effect of TEAS on hypotension after spinal anesthesia in patients undergoing cesarean section
