Objective: Orthostatic intolerance (OI) and autonomic dysfunction (AD) are common in adolescents and young adults. Patients experience multisystem symptoms including gastrointestinal (GI), postural orthostatic tachycardia syndrome (POTS),
Early mobilization after surgery is crucial for an enhanced recovery and can reduce complications associated with immobility. Symptoms such as nausea, vomiting, blurred vision and dizziness are however known to impede early mobilization. Together these symptoms comprise orthostatic intolerance (OI),
Because it is not clear that the induction of orthostatic intolerance in returning astronauts always requires prolonged exposure to microgravity, we investigated orthostatic tolerance and autonomic cardiovascular function in 16 healthy subjects before and after the brief micro- and hypergravity of
OBJECTIVE
Early postoperative mobilization is crucial for early ambulation to reduce postoperative pulmonary complications after lung resection. However, orthostatic intolerance (OI) may delay patient recovery, leading to complications. It is therefore important to understand the prevalence of and
Gastrointestinal (GI) symptoms of nausea, vomiting, and abdominal pain are common in patients with orthostatic intolerance (OI), including neurally mediated hypotension (NMH) and postural orthostatic tachycardia syndrome (POTS). Autonomic dysregulation is considered the underlying pathophysiology
BACKGROUND
Opioid analgesics are widely used to reduce postoperative pain and to enhance post-operative recovery. However, orthostatic intolerance (OI) induced by opioid containing intravenous patient controlled analgesia (IPCA) may hinder postoperative recovery. This study investigated factors that
OBJECTIVE
Early ambulation is essential for rapid functional recovery after surgery; however, orthostatic intolerance may delay recovery and cause syncope, leading to potential serious complications such as falls. Opioids may contribute to orthostatic intolerance because of reduced arterial pressure
BACKGROUND
A key element in enhanced postoperative recovery is early mobilization which, however, may be hindered by orthostatic intolerance, that is, an inability to sit or stand because of symptoms of cerebral hypoperfusion as intolerable dizziness, nausea and vomiting, feeling of heat, or blurred
Vagal and non-vagal pathways as well as several brainstem nuclei participate in vomiting in response to different emetic stimuli. Autonomic pathways involved in nausea are less well understood. Numerous gastrointestinal disorders with prominent nausea and vomiting including gastroparesis, cyclic
Early postoperative mobilisation is important for enhanced recovery, but can be hindered by orthostatic intolerance, characterised by dizziness, nausea, vomiting, feeling of heat, blurred vision and ultimately syncope. Although the incidence of orthostatic intolerance following total BACKGROUND
Current cosmetic breast augmentation relies on general anesthesia that normally requires 40 min to total recovery. With experience, the surgical procedure can be completed expediently in 20 min under tumescent anesthesia and propofol full sedation to achieve immediate postoperative
This review will address issues of effects of space flights on the body. Cardiovascular deconditioning often induce symptoms like orthostatic intolerance after flight, and during flight there will be space motion sickness during the first few days with headache, malaise, nausea and eventually
How microgravity influences autonomic function is still under investigation. Microgravity induces neuro-vestibular alterations and body fluid shift, and these two changes cause "space motion sickness(SMS)" and cardiovascular deconditioning. "Space motion sickness" is a autonomic syndrome that
OBJECTIVE
Lightheadedness, dizziness, chest discomfort, headache, pallor, palpitation, blurred vision, fatigue, and syncope are main symptoms of postural orthostatic tachycardia syndrome (POTS), but they are also common problems in clinical pediatrics. Besides, most of POTS cases have normal
Objective: To detail common comorbidities and procedures performed to evaluate functional nausea in children.
Study design: In total, 63 children age 7-18 years seen in a
