Sarcopenia and Orthostatic Hypotension
Orthostatic HypotensionSarcopeniaElderly patients generally have a tendency for having sarcopenia which refers to muscle loss that may be related to many factors. These patients also have a tendency to falls and injuries. Whether elderly sarcopenic patients have abrupt blood pressure drops upon standing remains unknown. Therefore, in this study, we sought to determine the incidence of orthostatic hypotension in sarcopenic elderly patients and compare it with elderly patients with no sarcopenia.

RAAS and Arterial Stiffness in SCI
Arterial StiffnessRenin Angiotensin Aldosterone System3 moreThe study is examining differences in central arterial stiffness, orthostatic changes in blood pressure, norepinephrine, and plasma renin in individuals with spinal cord injury compared with age-matched uninjured controls.
Study on Baroreceptor Function in Relation to Orthostatic Blood Pressure Regulation After Hip Surgery...
HypotensionOrthostatic1 moreThe purpose of this observational study is to evaluate the baroreceptor function in relation to surgical inflammation and orthostatic intolerance after elective hip arthroplasty. The main hypothesis is that baroreceptor function is attenuated after surgery and related to surgical inflammation.
Orthostatic Hypotension in Children With Acute Febrile Illness
FeverOrthostatic HypotensionObjective:to determent if children suffering from acute febrile illness has higher rate of orthostatic hypotension compared with children with no febrile illness. Design: a prospective cohort study. Subjects: children aged 4-18 year with fever (temperature > 38.) for up to 48 hours, presenting to the pediatric emergency department. Interventions: All subjects will have their blood pressure measured in supine position (after 5 minute of rest) and after 3 minute of standing.
Intraoperative Systemic Arterial Hypotension Secondary to Beach Positioning
HypotensionThis study aims at describing the systemic arterial hypotension secondary to intraoperative beach chair positioning. This is a non-interventional prospective study. The primary endpoint will be the intraoperative systemic arterial pressure measured at the arm. The secondary endpoints will include postoperative mortality, intensive care admission, post anesthesia care unit length of stay,
Hypotension Prediction Index Study (HPI Study)
HypotensionA prospective, single-arm, open-label, multicenter post-approval study to determine whether the use of the Acumen HPI Software to guide intraoperative hemodynamic management in non-cardiac surgery reduces the duration of intraoperative hypotension below a threshold of Mean Arterial Pressure (MAP)
Postoperative Changes in Optic Nerve Sheath Diameter in Patients Undergoing Spinal Anesthesia for...
Intracranial HypotensionThis is observational study. The investigator will measure optic nerve sheath diameter by ultrasound on the eye after cesarean section under spinal anesthesia.
Heart Rate Variability to Predict Hypotension Following Spinal Anesthesia in Cesarean Delivery
Cesarean SectionBased on the patient's heart rate variability, the analgesia nociception index (ANI) measures the activity of the autonomic nervous system and the sympathetic/parasympathetic nervous system and expresses it as a numerical value through a specific algorithm. The investigators will analyze it and see if it has the ability to predict severe hypotension following spinal anesthesia.
The Association Between Intraoperative Hypotension and Perioperative Stroke
Perioperative ComplicationIntraoperative HypotensionThe aim of this study is to investigate the association between the severity and duration of intraoperative hypotension and the incidence of perioperative stroke after non-cardiac and non-neurologic surgeries.The secondary aim of this study is to confirm the potential risk factors of the perioperative stroke.
