Case Reports
Mitral Valve Compression Induced Hypoxemia After Left Ventricular Assist Device Surgery: A Case Report.
Blood flow obstruction of left ventricular assist device (LVAD) is not uncommon. Causes of flow obstructions could be prepump, intrapump, and postpump. Clinical and echocardiographic parameters of LVAD obstruction vary substantially, ranging from being completely asymptomatic with unchanged functional status, normal filling pressures to frank cardiogenic shock. In the current case report, we present hypoxemia as an early presentation of LVAD inflow obstruction in the early postimplantation period in the absence of respiratory cause for hypoxemia.

Spontaneous intracranial hypotension is an uncommon disorder with symptoms including postural headache that can be debilitating to patients. Diagnosis is mainly clinical, aided by imaging of the brain and spine with or without diagnostic procedures. ⋯ We describe a case of a patient with clinical findings of spontaneous intracranial hypotension but with normal brain imaging. The patient responded to lumbar epidural blood patches and did not require additional tests to confirm the diagnosis.

Review Case Reports
Dexmedetomidine-Induced Massive Diuresis in a Patient Undergoing Spinal Fusion Surgery: A Case Report and Synthesis of the Literature.
Dexmedetomidine is an α2-adrenergic sedative-hypnotic medication used as an adjunct to general anesthesia. While experimental studies in animals have demonstrated a mild diuretic effect of dexmedetomidine, only recently have case reports described dexmedetomidine-induced diuresis in humans. ⋯ Here, we report a case of a 30-year-old woman undergoing cervical spinal fusion surgery who experienced a massive diuresis starting 30 minutes after receiving dexmedetomidine intravenous infusion. We discuss the differential diagnosis and synthesize the current literature on this rare effect.

Airway management remains a challenge in children, and the presence of a cleft palate further complicates the scenario. Endotracheal intubation, although definitive and most preferred, may be avoided for certain short-duration procedures wherein the use of laryngeal mask airway can allow quicker emergence. We present the successful airway management of 2 pediatric patients with cleft palate undergoing ophthalmological surgery, using AMBU® LMA® as the airway device of choice, which was further used as a rescue airway device in an emergent situation of "difficult to ventilate."
