Introduction: Pregnancy induces physiological changes, including alterations in cardiovascular dynamics, predisposing pregnant women to supine hypotension syndrome (SHS) during lower-segment cesarean section (LSCS) under spinal anesthesia. Various methods, including manual displacement of the uterus and use of wedges or cushions, have been proposed to prevent SHS, but their effectiveness remains variable. This study aimed to compare the efficacy of a novel 3D-printed uterine displacement device with that of a traditional wedge in preventing SHS during LSCS after spinal anesthesia.

Lower body negative pressure (LBNP) has been used for decades in humans to model arterial baroreceptor unloading and represents a powerful tool for evaluating cardiovascular responses to orthostatic challenge. However, LBNP studies in animals have been limited to conditions of anesthesia or sedation, where cardiovascular reflexes are altered. Given the consequent uncertainties, the usefulness of LBNP studies in these preclinical models has been severely hampered.

: While the diagnosis of postural orthostatic tachycardia syndrome (POTS) is based on heart rate (HR) and blood pressure (BP) criteria, the pathophysiology of POTS is not fully understood as multiple pathophysiological mechanisms have been recognized. Also, cardiac function, being dependent on preload, afterload, contractility, and HR, has not been properly studied. Preload and contractility changes can be inferred from stroke volume index (SVI) changes during a tilt test.

Introduction: Orthostatic intolerance is highly prevalent in patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and is caused by an abnormal reduction in cerebral blood flow (CBF). In healthy controls (HCs), the regulation of CBF is complex and cardiac output (CO) is an important determinant of CBF: a review showed that a 30% reduction in CO results in a 10% reduction in CBF. In previous and separate ME/CFS studies, we showed that CO and CBF decreased to a similar extent during tilt testing.

Diabetic cardiac autonomic neuropathy (CAN) is caused by damage to the autonomic nerve fibers that innervate the heart and blood vessels, leading to abnormalities in heart rate control and vascular dynamics. CAN encompasses symptoms such as exercise intolerance, orthostatic hypotension, cardiac denervation syndrome, and nocturnal hypertension. Neurogenic orthostatic hypotension (nOH), resulting from severe diabetic CAN, can cause symptomatic orthostatic hypotension.
