The complexity of neurosurgical procedures and their interactions with maternal and fetal physiologies are key factors in determining the overall maternal and fetal outcome. The literature and guidelines provide only partial information regarding the standard of care in these cases. The purpose of this Continuing Professional Development module is to review the issues related to common neurosurgical conditions and their optimal anesthetic management. ⋯ A multidisciplinary approach with good communication amongst all team members certainly plays a crucial role for successful management of such cases.

Case Reports
A case of acute respiratory distress syndrome responsive to methylene blue during a carcinoid crisis.
In a carcinoid crisis, numerous vasoactive agents, such as bradykinin precursors, serotonin, and histamine, are secreted by tumour cells. Bradykinin has been shown to increase pulmonary vascular permeability and hypotension in animal models; however, little is known about its in vivo effects or targeted pharmacotherapy in a carcinoid crisis. We describe a case of acute respiratory distress syndrome (ARDS) in a carcinoid crisis refractory to conventional antiserotonin and antihistamine therapies. ⋯ In a patient with a carcinoid crisis and ARDS refractory to conventional therapies, substantial hemodynamic and oxygenation improvements were observed following methylene blue administration. This case highlights the potential pathophysiologic role of bradykinin and methylene blue as an adjunct therapeutic option in carcinoid crises.
