Cyclic Vomiting Syndrome

Posted by e-Medical PPT Wednesday, June 30, 2010
Cyclic vomiting syndrome (CVS)is a condition whose symptoms are recurring attacks of intense nausea, vomiting and abdominal pain and/or headaches or migraines. Cyclic vomiting syndrome usually develops during childhood usually ages 3–7; although it often remits during adolescence, it can persist into adult life.
Aetiology of Cyclic vomiting syndrome is unknown.There is a strong suggestion of maternal inheritance, especially when the family history is significant for a mother with migraines.Persons who suffer from migraines in some cases also have cyclic vomiting syndrome. CVS can be a very painful and uncomfortable syndrome.It results in lack of sleep, abnormal eating, and lack of concentration. CVS differs from other forms of vomiting as it is an acute condition.Acid, bile, and (if the vomiting is severe) blood may be vomited.The most common therapeutic strategies for those already in an attack are maintenance of salt balance by appropriate intravenous fluids and, in some cases, sedation. Having vomited for a long period prior to attending a hospital, patients are typically severely dehydrated. Abortive therapy has limited success, but for a number of patients potent anti-emetic drugs such as ondansetron may be helpful in either preventing an attack, aborting an attack or reducing the severity of an attack.
