Case Reports
Compartment syndrome in a patient treated with perineural liposomal bupivacaine (Exparel).
Acute compartment syndrome is a condition that may result in sensorimotor deficits and loss of function of the affected limb as a result of ischemic injury. It is considered a surgical emergency and prompt diagnosis and treatment results in more favorable outcomes. The use of regional anesthesia is controversial in patients at risk for compartment syndrome due to concern of its potential to mask symptoms of the condition. ⋯ The diagnosis of compartment syndrome requires a high index of suspicion and prompt treatment. This patient's changing pattern of symptoms-rather than his pain complaints alone-resulted in the diagnosis of compartment syndrome treated with emergent fasciotomy in spite of finger numbness that was initially attributed to the liposomal bupivacaine. While the use of liposomal bupivacaine did not preclude the diagnosis of compartment syndrome in our patient, it should be used with caution in patients at risk for compartment syndrome until additional data, particularly regarding block characteristics, are available.

Dexmedetomidine suppresses intractable hiccup during anesthesia for cochlear implantation.
We report on the successful use of dexmedetomidine to treat persistent intractable hiccup in a child who underwent cochlear implantation under sevoflurane-fentanyl anesthesia.

A 3-year-old girl presented for routine closure of her tracheostomy site. She was intubated easily for the procedure, and the wound was closed with a drain in place. In recovery, the mother noticed fullness in the patient's submandibular region, and on examination, the girl had subcutaneous emphysema in the neck bilaterally. ⋯ The wound was again closed with a drain in place, and the patient was extubated uneventfully. After arriving to the pediatric intensive care unit for monitoring, the patient acutely developed respiratory distress and was found to have pneumomediastinum and pneumothorax and was emergently intubated. She was observed closely, and the following day, the pneumothorax improved, and she successfully extubated without further complication.

Anesthetic management of an ex utero intrapartum treatment procedure: a novel balanced approach.
Ex utero intrapartum treatment (EXIT) procedures are therapeutic interventions for fetuses with life-threatening airway abnormalities and/or other prenatally diagnosed congenital malformations requiring immediate neonatal extracorporeal membrane oxygenation support. Although certain anesthetic goals are common among EXIT procedures, many different approaches to their management have been described in the literature. Herein, we present a novel anesthetic approach to an EXIT procedure for fetal micrognathia and retrognathia. We also review the indications and anesthetic considerations for these procedures and highlight the need for multidisciplinary collaboration to optimize clinical outcomes.

To assess the safety of mechanical ventilation and effectiveness of extrinsic positive end-expiratory pressure (PEEP) (PEEPe) in improving peripheral oxygen saturation (SpO2) during direct microlaryngeal laser surgery; to assess the incidence, amount, and nature (dynamic hyperinflation or airflow obstruction) of ensuing intrinsic PEEP (PEEPi); and to find a surrogate PEEPi indicator. ⋯ During ventilation through small endotracheal tubes, PEEPi (mostly due to dynamic hyperinflation) is common. Hemodynamic complications, barotrauma, and O2 desaturation (reversible with PEEPe) are rare. Pawplateau provided by ventilators is useful in suspecting and monitoring the occurrence of PEEPi and allows detection of lung overdistension as PEEPe is applied.
