Acute respiratory alkalosis occurring after endoscopic third ventriculostomy -A case report-.
An endoscopic third ventriculostomy was performed in a 55-year-old man with an obstructive hydrocephalus due to aqueductal stenosis. The vital signs and laboratory studies upon admission were within the normal limits. Anesthesia was maintained with nitrous oxide in oxygen and 6% desflurane. ⋯ Anesthesia and operation were uneventful. However, he developed postoperative hyperventilation in the recovery room, and arterial blood gas analysis revealed acute respiratory alkalosis. We report a rare respiratory alkalosis that occurred after an endoscopic third ventriculostomy.

Damage to the cuff of EMG tube at endotracheal intubation by using a lightwand -A case report-.
Electromyogpraphic endotracheal tube (EMG tube) is a new device used to monitor recurrent laryngeal nerve integrity during thyroid surgery. The EMG tube has 2 pairs of electrodes on the surface of silicon-based tube reached to inner space of tube cuff. We experienced an unusual endotracheal tube-related problem from the distinct structural feature of the EMG tube. ⋯ After successful endotracheal intubation, we could not expand the pilot balloon and ventilate the patient effectively. We removed the EMG tube and found that one of electrodes of the EMG tube is bended and made a right angle with the long axis of the tube, and perforated the tube cuff. So we report this case to make anesthesia providers aware that much more attention is needed to use EMG tube during endotracheal intubation.

Position of dorsal root ganglia in the lumbosacral region in patients with radiculopathy.
When applying pulsed radiofrequency on dorsal root ganglia for treating chronic lower back pain, maximum efficiency can be expected when a needle is placed 1-2 cm peripheral to the dorsal root ganglion. The object of this study is to analyze images taken after adding contrast to transforaminal epidural injection, categorize root ganglia according to anatomical position, and provide a reference for efficient needle positioning in applying pulsed radiofrequency on dorsal root ganglia. ⋯ Positional categorization of dorsal root ganglia according to contrast images was proven to be good anatomical references for effective radiofrequency or blocking of dorsal root ganglia.

Transient bilateral vocal cord paralysis after endotracheal intubation with double-lumen tube -A case report-.
Vocal cord paralysis is one of the most serious anesthetic complications related to endotracheal intubation. The practitioner should take extreme care, as bilateral vocal cord paralysis can obstruct the airway and lead to disastrous respiratory problems. ⋯ We report a case of bilateral vocal cord paralysis detected after removal of a double-lumen endotracheal tube in a 67-year-old patient who underwent wedge resection by video-assisted thoracoscopic surgery. We also note that he recovered spontaneously without complications within a day.

Anesthetic experience of an adult patient with an unrecognized tracheal bronchus -A case report-.
We present a case of problematic tracheal intubation in an adult patient with an unrecognized tracheal bronchus. Immediately after tracheal intubation and position change to prone, bilateral breath sounds were almost absent, and there was a diminished tidal volume. ⋯ In the presence of tracheal bronchus, tracheal intubation may cause pulmonary complications. Anesthesiologists should keep in mind the anesthetic implications of tracheal bronchus, and must be familiar with the use of fiberoptic bronchoscopy for proper positioning of endotracheal tube.
