Neuraxial anesthesia in pregnant women with surgically corrected scoliosis: a case series.

Women with a history of surgical correction for adolescent idiopathic scoliosis are often denied neuraxial anesthesia during labor and delivery due to concerns of technical difficulties, anesthetic failures, inadvertent dural punctures, and hardware infections. We report four successful neuraxial procedures by four different anesthesiologists in three patients with previous posterior spinal instrumentation and fusion who delivered at our institution. The procedures include spinal anesthesia for cerclage, epidural analgesia for labor followed by successful conversion to epidural anesthesia for intrapartum cesarean delivery, spinal anesthesia for cesarean delivery, and epidural analgesia for vaginal delivery. Modern surgical techniques improve success rates of neuraxial anesthesia. Antenatal anesthesia consultation, knowledge of the lowest instrumented vertebra, familiarity with neuraxial ultrasound and multidisciplinary collaboration between orthopedic, obstetric, and anesthesiology teams are key. Anesthesiologists should offer and attempt neuraxial anesthesia if desired by these patients. Neuraxial anesthesia should not be withheld from them because they have spine instrumentation.
