Target-controlled total intravenous anesthesia associated with femoral nerve block for arthroscopic knee meniscectomy.
The increased popularity of minimally invasive surgical techniques reduced recovery time of procedures that were usually associated with prolonged hospitalization. This study reports the technique of total intravenous anesthesia with propofol and remifentanil associated with femoral nerve block using the inguinal perivascular approach. ⋯ All patients were maintained within established parameters.

Case ReportsSecond degree atrioventricular block Mobitz type I after administration of benzathine penicillin: case report.
Second degree atrioventricular block Mobitz type I is seen as a transitory change in the presence of inferior wall myocardial infarction or drug intoxication. The objective of this report was to present a case of second degree atrioventricular block Mobitz type I after administration of benzathine penicillin. ⋯ The patient developed second degree atrioventricular block Mobitz type I after the administration of benzathine penicillin.

Case ReportsCombined spinal-epidural block in a patient with amyotrophic lateral sclerosis: case report.
Amyotrophic lateral sclerosis starts between the fifth and sixth decades of life, causing degeneration and death of upper and lower motor neurons. When the muscles responsible for ventilation are affected, the patient dies of respiratory failure within a few years. ⋯ The evidence has demonstrated that neuroaxis blocks can be safely performed in patients with amyotrophic lateral sclerosis since it avoids manipulation of the airways and respiratory complications.

Case ReportsAnesthetic management of a patient with hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome). Case report.
Hereditary hemorrhagic telangiectasia (HHT), also known as Rendu-Osler-Weber syndrome, is an autosomal dominant disorder characterized by mucocutaneous and visceral vascular dysplasia associated with frequent episodes of epistaxis and gastrointestinal bleeding. The objective of this report was to describe the anesthesia of a patient with this syndrome. ⋯ Hereditary hemorrhagic telangiectasia is an autosomal dominant disorder that leads to mucocutaneous and visceral vascular dysplasia. Perioperative blood loss can be greater than expected in patients with this syndrome. Since bleeding does not result from a defect in the coagulation cascade but from the surgical exposure of malformed vascular structures, perioperative conduct includes the use of antifibrinolytics, adequate homeostasis, and induced hypotension in the absence of contraindications. Preanesthetic evaluation should include the search for brain, lung, and gastrointestinal vascular malformation.

Randomized Controlled Trial Comparative StudyEphedrine versus phenylephrine: prevention of hypotension during spinal block for cesarean section and effects on the fetus.
Hypotension during spinal block for cesarean section is secondary to the sympathetic blockade and aorto-caval compression by the uterus and it can be deleterious to both the fetus and the mother. Ephedrine and phenylephrine improve venous return after sympathetic blockade during the spinal block. The objective of this study was to compare the efficacy of ephedrine and phenylephrine in the prevention and treatment of maternal hypotension during spinal block and to evaluate their side effects and fetal changes. ⋯ Ephedrine was more effective than phenylephrine in the prevention of hypotension. Both drugs had similar incidence of side effects. Fetal repercussions were less frequent with phenylephrine and were transitory with the use of ephedrine.
