Acute hypoxemia in a parturient with primary ciliary dyskinesia following the administration of intravenous oxytocin: a case report.

Purpose: We present the case of a parturient diagnosed with primary ciliary dyskinesia with secondary bronchiectasis who developed significant hypoxemia following administration of intravenous oxytocin during Cesarean delivery under spinal anesthesia. This case suggests that oxytocin can affect pulmonary vascular tone and interfere with the protective effects of hypoxic vasoconstriction.

Clinical Features: A 35-yr-old primigravida at 37 weeks gestation presented for a scheduled Cesarean delivery due to breech positioning and fetal abnormalities.

Regional anesthesia for the management of limb injuries in space.

Traumatic injuries continue to present a threat to the success of current and future spaceflight missions. The magnitude of this threat will grow as the frequency of extravehicular activities is increased and missions venture beyond low Earth orbit and further away from terrestrial medical support. The capability to render definitive treatment to crewmembers who suffer a serious traumatic injury while in space is relatively limited at present.
