Comparative Study Clinical Trial Controlled Clinical Trial
Assessment of patient position for fiberoptic intubation using videolaryngoscopy.
To compare laryngoscopic appearance obtained during flexible fiberoptic laryngoscopy with the patient's atlanto-occipital joint in the neutral and extended positions. ⋯ Atlanto-occipital extension is a useful maneuver during attempted fiberoptic intubation.

To assess the factors affecting the distance from skin to epidural space. ⋯ Both the patient's weight and position during epidural needle placement are important factors influencing DS-ES. A change from the sitting to the lateral position may increase DS-ES, causing catheter dislodgment and consequent inadequate analgesia. Clinical studies relating DS-ES to inadequate analgesia must take these factors into account.

To determine if acquired long QT syndrome following right or left, radical or modified, neck dissections result in malignant arrhythmias or deaths. ⋯ Acquired long QT syndrome following radical neck dissection, without congenital, metabolic, or pharmacologic disturbance, is unlikely to trigger malignant arrhythmias, as previously reported for right radical neck dissection.

Case Reports
Phrenic nerve injury following scalenectomy in a patient with thoracic outlet obstruction.
We present a case in which a patient with normal pulmonary reserve experienced orthopnea and hypoxia secondary to unilateral diaphragmatic paralysis following right scalenectomy. This operation was performed in an attempt to relieve neurovascular compromise at the thoracic outlet. To our knowledge, this association has not been previously described in the literature.
