Perioperative serotonin syndrome has been associated with a number of medications and herbal supplements. We report a patient who developed serotonin syndrome immediately after an endoscopic procedure in which the preoperative use of black seed oil appears to have played a role in stimulating the syndrome. Black seed oil has not been previously reported in association with perioperative serotonin syndrome. Anesthesia professionals should be aware that patients taking black seed oil supplements may develop serotonin syndrome postoperatively.

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.
