Subarachnoid hemorrhage (SAH) during pregnancy is a rare event, and about half the cases are due to arteriovenous malformations (AVM). The authors describe the anesthetic approach of a 39 week pregnant patient scheduled for cesarean section, with a history of SAH due to AVM at 22 week gestation. ⋯ There are very few published cases of anesthetic approach for pregnant women with symptomatic AVM. All decisions made by the multidisciplinary team, from choosing to continue the pregnancy to the ideal time for AVM intervention and type of anesthesia and analgesia, were weighted according to the risk of brain damage. Regarding the anesthetic procedure, the authors emphasize the need for hemodynamic stability.

This study investigates analgesic and nociceptive effects of adding dexmedetomidine to bupivacaine neuraxial anesthesia through Tail-flick (TF) and Hot-plate (HP) tests and the pathohistological changes on spinal nerves and nerve roots through light microscopy. ⋯ There were no apparent pathohistological changes at least 24 hours after the intrathecal administration of a single dose of dexmedetomidine 3 μg and 10 μg. Dexmedetomidine added to bupivacaine for spinal block improves analgesia and prolongs block duration.
