Obstetric anesthesia considerations in Kearns-Sayre syndrome: a case report.

Kearns-Sayre syndrome (KSS) is a rare mitochondrial myopathy that usually develops before 20 years of age. It demonstrates multisystemic involvement with a triad of cardinal features: progressive ophthalmoplegia, pigmentary retinopathy, and cardiac conduction abnormalities. In addition, patients might have cerebellar ataxia, a high content of protein in the cerebrospinal fluid, proximal myopathy, multiple endocrinopathies, and renal tubular acidosis.

Small dose spinal bupivacaine for Cesarean delivery does not reduce hypotension but accelerates motor recovery.

Background: Maternal hypotension occurs in 60-94% of Cesarean deliveries with 10-15 mg spinal bupivacaine. Reduced doses of bupivacaine may decrease the incidence of hypotension, nausea, and vasopressor use. The primary objective of this study was to compare 4.

Evidence that intravenous vasopressors can affect rostral spread of spinal anesthesia in pregnancy.

Background: The authors have previously observed an apparent association between rostral spread of spinal anesthesia and choice of intravenous vasopressor given to maintain maternal systolic arterial pressure during cesarean delivery. This study tested the hypothesis that an intravenous infusion of phenylephrine can reduce rostral spread of spinal anesthesia in pregnancy, compared with ephedrine.

Methods: The study was randomized and double blind.
