https://www.selleckchem.com/products/Deforolimus.html Congenital methemoglobinemia is a rare disease that is easily overlooked in its mild form. It can lead to tissue hypoxia as methemoglobin does not possess oxygen-carrying capacity. Its management approach depends on the severity of the symptoms, methemoglobin level, and associated medical conditions. The perioperative management of congenital methemoglobinemia is well described in the literature; however, its management in children with congenital heart disease and undergoing cardiac surgery using cardiopulmonary bypass has not been reported. We present a case and its management where congenital methemoglobinemia was detected in the operating room in a child scheduled for cardiac surgery.Paragangliomas (PGLs) are rare tumors with an incidence of 0.007% in pregnant women. Patients with PGLs commonly present with hypertension and tachycardia. This case report describes the evaluation and management of a multiparous woman at 32 weeks of gestation with syncope, hypoxia, and tachycardia as unusual presenting symptoms of PGL. Her symptoms were attributable to paradoxical effects of circulating catecholamines on downregulated alpha-adrenergic receptors resulting in decreased systemic vascular resistance.The right supraclavicular fossa view allows for ultrasonographic visualization of the central veins. A preprocedural scan of an asymptomatic 38-year-old man referred for peripherally inserted central catheter (PICC) insertion revealed a large thrombus in the right brachiocephalic vein. Hence, a left-sided insertion was chosen. Using the right supraclavicular view, the PICC was visualized in the left brachiocephalic vein, and the catheter was followed to its final position, avoiding contact with the thrombus. Thus, the right supraclavicular fossa view allowed for the detection of relevant pathology and facilitated an alternative feasible strategy with real-time catheter guidance during PICC insertion.We present a case of
