PY - 2023 T2 - Obstetric Anesthesia: Quick References & Practical Guides AB - Morphine, fentanyl, sufentanil, and epinephrine have been widely and safely used as adjuvants for labor analgesia and for cesarean delivery anesthesia. An introduction of alpha2-adrenergic agonist dexmedetomidine (DEX) in obstetric anesthesia could provide the unique analgesic benefit without side effects of opioids such as pruritus, urinary retention, hyperalgesia, and respiratory depression. The addition of DEX to neuraxial local anesthetics produces a significant prolongation in the duration of sensory and motor blockage and reduction in post cesarean opioid requirement.1 Various animal studies have been conducted using intrathecal DEX at a dose range of 2.5 to 100 μg without any neurotoxicity, similarly, without any postoperative neurological deficit in human studies.
