Procedures
Hydrocephalus treatment is surgical, creating a way for the excess fluid to drain away. In the short term, an external ventricular drain (EVD), also known as an extraventricular drain or ventriculostomy, provides relief. In the long term, some people will need any of various types of cerebral shunt. It involves the placement of a ventricular catheter (a tube made of silastic) into the cerebral ventricles to bypass the flow obstruction/malfunctioning arachnoidal granulations and drain the excess fluid into other body cavities, from where it can be resorbed. Most shunts drain the fluid into the peritoneal cavity (ventriculoperitoneal shunt), but alternative sites include the right atrium (ventriculoatrial shunt), pleural cavity (ventriculopleural shunt), and gallbladder. A shunt system can also be placed in the lumbar space of the spine and have the CSF redirected to the peritoneal cavity (lumbar-peritoneal shunt). An alternative treatment for obstructive hydrocephalus in selected people is the endoscopic third ventriculostomy (ETV), whereby a surgically created opening in the floor of the third ventricle allows the CSF to flow directly to the basal cisterns, thereby shortcutting any obstruction, as in aqueductal stenosis. This may or may not be appropriate based on individual anatomy. For infants, ETV is sometimes combined with choroid plexus cauterization, which reduces the amount of cerebrospinal fluid produced by the brain. The technique, known as ETV/CPC, was pioneered in Uganda by neurosurgeon Benjamin Warf and is now in use in several U.S. hospitals. Hydrocephalus can be successfully treated by placing a drainage tube (shunt) between the brain ventricles and abdominal cavity.
Meclizine, sold under the brand name Bonine, among others, is an antihistamine used to treat motion sickness and dizziness (vertigo). It is taken by mouth. Effects generally begin in an hour and last for up to a day.Common side effects include sleepiness and dry mouth. Serious side effects may include allergic reactions. Use in pregnancy appears safe, but has not been well studied while use in breastfeeding is of unclear safety. It is believed to work in part by anticholinergic and antihistamine mechanisms.Meclizine was patented in 1951 and came into medical use in 1953. It is available as a generic medication and often over the counter. In 2019, it was the 150th most commonly prescribed medication in the United States, with more than 4 million prescriptions. Medical uses
Meclizine is used to treat symptoms of motion sickness. Safety and efficacy in children younger than twelve years of age has not been established; therefore, use in this population is not recommended. Meclizine should be taken with caution in the elderly due to increased risk of confusion and amnesia. Motion sickness
Meclizine is effective in inhibiting nausea, vomiting, and dizziness caused by motion sickness.The drug is safe for treating nausea in pregnancy and is a first-line therapy for this use. Doxylamine is similarly safe. Meclizine may not be strong enough for especially sickening motion stimuli and second-line defenses should be tried in those cases. Vertigo
Meclizine may be used to treat motion sickness or vertigo such as in those with Ménières disease.
