BACKGROUND AND OBJECTIVE Since its introduction in the 80s, transesophageal echocardiography (TEE) not only gained popularity but also experienced great advances in technology and currently it is an extremely valuable tool in the intraoperative period. In Brazil, there are no published data on the profile of its use in the intraoperative period by anesthesiologists. The objective of this study ...

Background: Pulse Oximeter monitoring has become so common over previous decades that in some health care units, blood oxygen level is now considered as the fifth vital sign. However, it seems there is still some lack of knowledge and/or experience among medical staff operating pulse oximeter and interpreting its results. The aim of this study was to investigate and compare the knowledge on Pul...

Castleman's disease (CD) is a rare lymphoproliferative disorder of undetermined etiology. Unicentric Castleman's disease is confined to a single lymph node; it is usually asymptomatic though sometimes has local manifestations related to mass effects. In contrast, multicentric Castleman's disease (MCD) typically presents with lymphoid hyperplasia at multiple sites; it is associated with systemic...

Leigh syndrome (LS) is a rare disease mainly affecting the central nervous system due to the abnormalities of mitochondrial energy generation and seen in early childhood with progressive loss of movement, mental abilities, seizures, nystagmus, ophthalmoparesis, optic atrophy, ataxia, dystonia, or respiratory failure. Anesthesia and surgery exacerbate the risks of aspiration, wheezing, and breat...

A limited number of cases of anesthetic management of Rubinstein-Taybi Syndrome (RTS) have been reported since this syndrome was first diagnosed in 1963. After some well-publicized complications following anesthesia for patients with RTS, there has been great interest in avoiding all precipitant factors and careful monitoring during intraoperative and postoperative periods. This case series exa...

The true incidence of seizures caused by general anesthetic drugs is unknown. Abnormal movements are common during induction of anesthesia, but they may not be indicative of true seizures. Conversely, epileptiform electrocortical activity is commonly induced by enflurane, etomidate, sevoflurane and, to a lesser extent, propofol, but it rarely progresses to generalized tonic-clonic seizures. Eve...
