In a well-characterized animal model of large ischemic stroke, total lung water content increases, which is likely neurogenic in origin. Attenuation of stroke-associated increases in lung and brain water content with continuous infusion of hypertonic saline may have therapeutic implication in the treatment of cerebral and pulmonary edema following ischemic stroke.

Combined spinal-epidural (CSE) analgesia is a frequently used method of labor analgesia. Although it is considered safe and effective, CSE can be complicated by local anesthetic systemic toxicity (LAST), a potentially life-threatening condition. We present a case of LAST that developed in a primigravida 50 minutes after uneventful placement of a CSE. Her symptoms resolved within 10 minutes of administering intralipid emulsion. She subsequently underwent cesarean delivery under spinal anesthesia for failure to progress without sequelae in the mother or infant. LAST in pregnancy can occur at traditionally subthreshold dosing; anesthesiologists must be vigilant to ensure prompt and effective treatment.
