Initial experience with implanted peripheral nerve stimulation for the treatment of refractory cephalgia.
To report 4 cases of improved pain control and function in patients with chronic cephalgia secondary to chronic headaches and/or trigeminal neuralgia. ⋯ Initial experience suggests that refractory pain secondary to chronic migraines and trigeminal neuralgia may respond to peripheral nerve stimulation. Further studies are indicated to evaluate efficacy over the long term and to elucidate the optimal array and implantation technique.

To examine the history of pediatric endotracheal intubation and the issues surrounding the change from uncuffed endotracheal tubes to cuffed endotracheal tubes, including pediatric airway anatomy, endotracheal tube design, complications, and safety concerns. ⋯ Although the use of cuffed endotracheal tubes in infants and children remains a topic of debate, the literature supports this change in practice. Meticulous attention must be given to intracuff pressure. Cuffed endotracheal tubes designed especially for the pediatric patient may increase the margin of safety.

α(2)-Agonists are a novel class of drugs with mechanisms of action that differ from other commonly used anesthetic drugs. They have neuroprotective, cardioprotective, and sedative effects. These unique characteristics make them potentially useful during neuroanesthesia and intensive care. We review the effects of dexmedetomidine on cerebral blood flow and cerebral metabolism, along with recent advances in using α(2)-agonists in neuroanesthesia and neurointensive care.

Epidural Anesthesia for Cesarean Delivery in a Patient With Severe Pulmonary Artery Hypertension and a Right-to-Left Shunt.
A 38-year-old woman with severe pulmonary artery hypertension and a right-to-left shunt of unknown etiology presented at 32 weeks' gestational age. Determination of the cause of her pulmonary hypertension by transesophageal echocardiography was delayed until after delivery secondary to anesthetic risk. ⋯ Transesophageal echocardiography after delivery revealed a patent foramen ovale, indicating a diagnosis of idiopathic pulmonary artery hypertension and a very poor prognosis. Differentiating between Eisenmenger syndrome and idiopathic pulmonary artery hypertension may not be important for determining the optimal anesthetic management of patients with pulmonary hypertension but is important in assessing long-term prognosis.

Anesthesia care providers frequently exchange care of patients among one another. This daily process of information exchange could be a potential source for adverse events. ⋯ These data will be used to improve the method of the patient care handoff and have assisted us in devising techniques that can be incorporated into daily practice, advancing the safety of handoffs and decreasing complications. A handoff screen has been included on the electronic anesthesia record, encouraging a more formalized procedure for handoffs, thereby promoting patient safety.
