Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) maintains oxygenation and blunts the partial pressure of carbon dioxide (PaCO2) rise in nonpregnant subjects during apnea. Physiologic changes of pregnancy may attenuate the utility of THRIVE. ⋯ However, PaCO2 rise more closely mirrors classic apneic oxygenation in nonobstetric patients. The PaCO2 elevation and subsequent acidosis may limit the utility of THRIVE for prolonged apnea in pregnant surgical patients.

Transverse myelitis (TM) is a rare neurologic disorder of acute inflammation resulting in spinal cord injury. Chronic pain in TM is a significant detriment to quality of life. ⋯ He reported 70% improvement during the trial and was subsequently implanted with an SCS. He continues to experience significant pain relief and functional improvement (>80%) with conventional paresthesia programming at the 9-month follow-up.
