An airway-exchange catheter (AEC) can increase the safety of exchanges of endotracheal tubes (ETTs); however, the procedure is associated with potential risks. We describe a case of esophageal misplacement of a single-lumen ETT after switching from a double-lumen tube, despite the use of an AEC as a guidewire. To avoid this, physicians should consider the insertion depth and maintenance depth of the AEC and should verify its position before changing ETTs and should perform, if possible, with simultaneous visualization of the glottis with direct or video laryngoscopy during the exchange. Additionally, the new ETT position should be confirmed by auscultation, end-tidal carbon dioxide, and portable chest X-ray.

This survey aimed to assess the extent of practice of the Middle Eastern anesthesiologists in the use of neuromuscular blocking agents (NMB) in 2012. ⋯ We believe that more could be done to increase the awareness of the Middle Eastern anesthesiologists about the high incidence of PROC (>20%) and the need for routine monitoring of neuromuscular function. This could be accomplished with by developing formal training programs and providing official guidelines.

Interscalene block is commonly associated with reversible ipsilateral phrenic nerve block, recurrent laryngeal nerve block, and cervical sympathetic plexus block, presenting as Horner's syndrome. We report a very rare Pourfour Du Petit syndrome which has a clinical presentation opposite to that of Horner's syndrome in a 24-year-old male who was given interscalene block for open reduction and internal fixation of fracture upper third shaft of left humerus.

Infraclavicular approach to the brachial plexus sheath provides anesthesia for surgery on the distal arm, elbow, forearm, wrist, and hand. It has been found that evoked distal motor response or radial nerve-type motor response has influenced the success rate of single-injection infraclavicular brachial plexus block. ⋯ Stimulating the posterior cord guided by a nerve stimulator before local anesthetic injection is associated with greater extent of block (in the number of motor nerves blocked) and effectiveness of block (in reporting no pain during the surgery) than stimulation of either the lateral or medial cord.
