Routine administration of TA during total knee arthroplasty to patients without history of thromboembolic disease is associated with a 67% reduction in RBC transfusions and, in those transfused, with a reduction in the number of units administered. TA treatment was not associated with an increase in thromboembolic complications. Transfusion costs are significantly reduced.
Perioperative warming was associated with a higher incidence of cognitive dysfunction at 4 days after total knee replacement in patients >65 years of age.
In this study TNS was associated with isobaric mepivacaine 20 mg/ml, with an incidence of 7.5%, and with isobaric lidocaine 20 mg/ml, with an incidence of 2.5%, in patients having orthopaedic procedures in the supine position.
SummaryWe present another case of delayed intracerebral hemorrhage after a ventriculoperitoneal (VP) shunting procedure. In this case, a right occipital intraparenchymal hematoma and associated intraventricular hemorrhage occurred six days after the operation for hydrocephalus secondary to subarachnoid hemorrhage in a 64 year old woman. It is a rare complication of VP shunting, with few cases reported previously in the literature. The presumed mechanism is the erosion of a cerebral blood vessel secondary to a close contact with the ventricular catheter; bleeding disorder, vascular malformation, head trauma or brain tumor were excluded in this patient.KEY WORDS: Intracerebral hemorrhage.

Caso clínico y revisión de la literatura Resumen Presentamos un caso de hemorragia intracerebral tardía tras la colocación de una derivación ventriculoperitoneal. Una paciente de 64 años de edad, con hidrocefalia secundaria a una hemorragia subaracnoidea, sufre una hemorragia intraparenquimatosa occipital derecha con hemorragia intraventricular secundaria seis días después de la intervención quirúrgica. Se trata de una complicación rara de la derivación ventriculoperitoneal, con pocos casos publicados anteriormente. El mecanismo supuesto es la erosión de un vaso sanguíneo secundaria a un íntimo contacto con el catéter proximal de la derivación; trastornos sanguí-neos, malformaciones vasculares cerebrales, traumatismo craneal o tumor cerebral fueron excluidos en esta paciente.PALABRAS CLAVE: Hemorragia intracerebral. Derivación ventriculoperitoneal. Hidrocefalia. Complicación postquirúrgica. Catéter ventricular.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
