Active clinical trials for "Hypotension"

The goal of this randomized double blind controlled trial is to learn about the effects of calcium when it is given prior to diltiazem for patients with atrial fibrillation ( a type of irregular heart beat) who have rapid ventricular response ( a pulse over 100 beats per minute). Normally diltiazem 0.25mg/kg (max 20mg) is given to slow the heart rate. We will give Placebo versus Calcium Gluconate 2gm given prior to diltiazem. The main questions it aims to answer are: Does calcium decrease the incidence of low blood pressure (a side effect of diltiazem)? How does calcium effect the action of diltiazem? Does it interfere with the desired decrease in heart rate? Participants will receive either placebo or calcium immediately prior to the administration of diltiazem. Their blood pressure and pulse will be measured: prior to study drug administration post study drug and prior to diltiazem administration 3 minutes post start of diltiazem 5 minutes post start of diltiazem 10 minutes post start of diltiazem 20 minutes post start of diltiazem 30 minutes post start of diltiazem Researchers will compare the placebo group to the calcium group to see if there is a difference in the blood pressure and pulse.

This study was a single-center, prospective, 2-year observational cohort study. The study subjects were ICU patients requiring vasopressor drugs and requiring sedation. According to the use of ciprofol or propofol in the treatment plan (determined by the doctor in charge according to the condition of the subjects), they were divided into groups: ciprofol group and propofol group. A total of 456 subjects were planned to be enrolled, including 304 subjects in the cyclopofol group and 152 subjects in the propofol group. The data of this study were obtained by extracting the routine clinical diagnosis and treatment records of the enrolled subjects.

Elderly patients have a higher risk of post-induction hypotension (PIH). The decreased cardiovascular autonomic function at baseline in elderly patients may contribute to the development of PIH. The objective of our study is to effect of preoperative cardiovascular autonomic modulation in PIH, we will recruit elderly patients who are going to have general anesthesia surgery and measure preoperative baroreflex sensitivity (BRS) and heart rate variability (HRV). The primary outcome will be PIH. Secondary outcomes included: early intraoperative hypotension, postoperative complications, and 30-day postoperative mortality.

This is a prospective single-center randomized crossover control study that aims to evaluate the effects of non-invasive transcutaneous spinal cord stimulation in patients with known or suspected orthostatic hypotension.

In critically ill patients with liver disease like cirrhosis or ACLF, fluid therapy needs to be instituted after identification of patients who will be fluid responsive and initiate appropriate inotropes early to prevent the mortality associated with fluid overload. The parameters and methodology used for assessing fluid responsiveness have been studied earlier, but the optimum method is not established. Existing recommendations based on data regarding fluid responsiveness and choice of fluid for resuscitation from intensive care units in general cannot be applied to those with liver disease as the hemodynamic alterations that occur with liver disease, presence of hypoalbuminemia at baseline and presence of cardiac dysfunction interfere with the conventional methods of fluid status assessment, fluid responsiveness as well as the response to different types of resuscitation fluids. Therefore the investigators attempt to compare various methods to estimate current intravascular volume status of patient which could be helpful in guiding fluid therapy.

The purpose of this research is to determine the efficacy of paraspinal vein embolization for treatment of digital subtraction myelography (DSM) or CT myelography (CTM) confirmed cerebrospinal fluid (CSF)-venous fistulas so that researchers can inform the development and design of future clinical trials of this technique.

Incidence and pathophysiologic hemodynamics of postoperative orthostatic intolerance and orthostatic hypotension in patients receiving antihypertensives

Glycemic imbalances are very common in shock patients admitted to intensive care units. A blood glucose control every 2 hours is routinely performed in patients requiring insulin therapy. In practice, we use a protocol and management software called "CPG" (Personalized Control of Blood Glucose). This involves taking capillary samples from the fingertips. In addition to the pain generated, local haematomas and sensitivity disorders have been described. Night-time sampling also leads to repeated awakenings. The "CGM GUARDIAN 2" system has been validated for the measurement of glucose in interstitial fluid in insulin-dependent diabetic patients. An electrode is placed on the patient's abdomen or arm for up to 6 days. This electrode consists of a needle that is inserted subcutaneously only during the placement. The sugar level is read using a sensor placed on the electrode and an insulin pump (which will not deliver therapy (for our study) and which will be used only as an information reader to know the glucose level and trends). Interstitial fluid is automatically drawn from the electrode every minute and averaged every 5 minutes. This device has not yet been validated in resuscitation patients.

The parturients may suffer from hypotension after spinal anesthesia and the incidence could be as high as 70-80% when pharmacological prophylaxis is not used. Acupuncture was reported to treat hypotension both in human and animal studies. Possible mechanisms include modulating cardiovascular and sympathetic system. In this prospective, double-blinded, randomized clinical trial, we tend to investigate the effect of transcutaneous electric acupoint stimulation (TEAS) on hypotension in parturients undergoing cesarean section.

The number of elderly patients undergoing elective surgery has been growing in recent years. Elderly patients often have a variety of underlying diseases, including hypertension, coronary heart disease, diabetes, arteriosclerosis, etc., which increase the risk. When the elderly receive general anesthesia, hypotension often occurs after anesthesia induction. Once hypotension occurs, it may lead to myocardial ischemia, myocardial infarction, stroke and other serious complications. Therefore, in clinical anesthesia, a simple, quick and accurate prediction method is needed to evaluate and predict the risk of hypotension in elderly patients after induction, so that appropriate intervention measures can be taken in advance to reduce the incidence of hypotension in elderly patients after induction, thus reducing the occurrence of related complications and ensuring the safety of anesthesia and surgery.Carotid Artery Corrected Flow Time（FTc） is a recently developed volumetric predictor, which refers to the time between the the onset of systolic flow until the closure of the aortic valve. It is related to cardiac preload and can reflect cardiac output to a certain extent. It is considered as a reliable indicator for evaluating volume status and volumetric reactivity. Therefore, this study will investigate the predictive value of carotid corrected blood flow time in the elderly after general anaesthesia induced hypotension.
