Anesthetic interactions of midazolam and fentanyl: is there acute tolerance to the opioid?

abstract：BACKGROUND:Obstetrics carries high medical liability risk. Maternal death and newborn death/brain damage were the most common complications in obstetric anesthesia malpractice claims before 1990. As the liability profile may have changed over the past two decades, the authors reviewed recent obstetric claims in the Ame...
