Active clinical trials for "Hypotension"

This study is a retrospective work involving the review of patients who were scheduled for VP or LP shunt in Siriraj Hospital, Mahidol University, Thailand. The sample size calculation was based on the rule of thumbs of the logistic regression comprising 18 risk factors. The incidence of post-induction hypotension according to our institution's pilot study November 2019-January 2020) was 47%. With 10% addition for missing data and other possible reasons, the sample size was 426. The primary objective of the study is to report the factors associated with post-induction hypotension in iNPH patients undergoing VP or LP shunt procedures. Our secondary objective is to determine the incidence of post-induction hypotension in these patients.

An International, multicenter, epidemiological observational study investigating the prevalence of Transthyretin-Related Familial Amyloidotic Polyneuropathy (TTR-FAP) in participants with small fiber polyneuropathy of no obvious etiology.

Patients undergoing surgery in beach chair position (BCP) are at risk for cerebral ischaemia. The impacts of arginine vasopressin (AVP) on haemodynamics and cerebral oxygenation are evaluated during surgery in BCP.

Blood copeptin will be measured during the routine treatment of neonates, children and adolescents on the Intensive Care Unit of the University Children's Hospital Zurich at different time points (admission, 12, 24, 48, 96, 168 hours after admission). These values will be primarily analysed for their variability and their association with arterial hypotension. Blood samples will be drawn together with otherwise medically indicated blood withdrawals to avoid extra harm. Further, copeptin values will be compared to clinical and vital parameters, all of them open-label available during clinical routine. Copeptin's predictive value for patients' outcome will be analysed as secondary outcome.

The aim of the present study is to quantify the dose and usage of sympathomimetics used in caesarean section.

Specific aim 1: The specific aim of this study is to compare cardiac output measurements as well as cardiac index, and stroke volume obtained via thermodilution during a cardiac catheterization with data obtained by the ClearSight cardiac output monitoring system. Specific aim 2: To compare arterial blood pressure measurements obtained by arterial line with arterial waveform measurements obtained by the ClearSight System. The hypothesis is: Cardiac output measurements or arterial blood pressure measurements taken non-invasively with the ClearSight system in pediatric patients who are either undergoing cardiac catheterization or have an arterial line will correlate with cardiac output measurements taken by pulmonary artery catheter thermodilution or arterial pressures measured by an arterial line.

Patients with acute hip fractures are old and vulnerable. With a majoriry classified as being ASA 3 or more. Frequently they receive spinal anesthesia perioperatively inducing hypotension. Even a short hypotensive period may induce postop cardiac T roponinT leakage as well as renal failure noted by Changes in Serum Creatinin or Cýstatin C This will be investigated and correlated to intraoperative hypotension as step one. Preliminary this will be followed by an intervention with vasopressor treatment perioperatively to preserve an adequte MABP

To investigate biomarker reflects systemic or specific organ perfusion well, we are going to the observational comparison study using several hemodynamic monitoring methods in the premature infants. It includes near-infrared spectroscopy (NIRS), pulse oximetry with perfusion index (PI) and pleth variability index (PVI) and functional echocardiography.

The purpose of this observational research study is to examine how point-of care ultrasound affects the workup and management of perioperative complications for specific clinical scenarios of low blood pressure (hypotension), low blood oxygen (hypoxemia), in the post- anesthesia care unit (PACU).

Intra operative hypotension is a risk factor in pediatric anesthesia (McCann ME et al.Pediatr Anesth 2014; 24: 68-73). In summary, the study aims at examine if ultrasound assessment of the diameter and collapsibility index of the subclavian vein is correlated to fasting time and if they are correlated to the degree of hypotension seen post anesthesia induction in children undergoing general anesthesia.
