ReviewPostural tachycardia syndrome: a heterogeneous and multifactorial disorder.
Postural tachycardia syndrome (POTS) is defined by a heart rate increment of 30 beats/min or more within 10 minutes of standing or head-up tilt in the absence of orthostatic hypotension; the standing heart rate is often 120 beats/min or higher. POTS manifests with symptoms of cerebral hypoperfusion and excessive sympathoexcitation. The pathophysiology of POTS is heterogeneous and includes impaired sympathetically mediated vasoconstriction, excessive sympathetic drive, volume dysregulation, and deconditioning. ⋯ A literature search of PubMed for articles published from January 1, 1990, to June 15, 2012, was performed using the following terms (or combination of terms): POTS; postural tachycardia syndrome, orthostatic; orthostatic; syncope; sympathetic; baroreceptors; vestibulosympathetic; hypovolemia; visceral pain; chronic fatigue; deconditioning; headache; Chiari malformation; Ehlers-Danlos; emotion; amygdala; insula; anterior cingulate; periaqueductal gray; fludrocortisone; midodrine; propranolol; β-adrenergic; and pyridostigmine. Studies were limited to those published in English. Other articles were identified from bibliographies of the retrieved articles.

To investigate whether patients with postural orthostatic tachycardia syndrome (POTS) developed unexpected perioperative complications. ⋯ Intraoperative hypotension, but not tachycardia, was observed in three of 13 patients with POTS who received general anesthesia for a variety of surgical procedures using multiple medications and techniques.

Postural orthostatic tachycardia syndrome (POTS) is a disorder characterized by postural tachycardia in combination with orthostatic symptoms without associated hypotension. Symptoms include light-headedness, palpitations, fatigue, confusion, and anxiety, which are brought on by assuming the upright position and usually relieved by sitting or lying down. ⋯ We present an adolescent with POTS who required anesthetic care during posterior spinal fusion for the treatment of scoliosis. The potential perioperative implications of this syndrome are discussed.

Case Reports
Anaesthetic management of a parturient with the postural orthostatic tachycardia syndrome: a case report.
Postural orthostatic tachycardia syndrome encompasses a group of disorders characterized by orthostatic intolerance. We describe the anaesthetic management of analgesia for labour and of Caesarean section in a parturient suffering from this disorder. ⋯ Slow titration of epidural analgesia and anaesthesia after an adequate fluid preload was undertaken to minimize hypotension and subsequent tachycardia. Neuraxial opioid, combined with non-steroidal anti-inflammatory drugs and bilateral iliohypogastric and ilioinguinal nerve blocks were used to optimize postoperative analgesia.

Case ReportsPostural orthostatic tachycardia syndrome: anesthetic implications in the obstetric patient.
We report the anesthetic management of a parturient with postural orthostatic tachycardia syndrome. This syndrome is associated with hemodynamic instability, which can be worsened by the physiology of labor and delivery. We discuss anesthetic concerns with this disease in the parturient and suggest approaches for management of this disease.
