Is the Airtraq optical laryngoscope effective in tracheal intubation by novice personnel?
Macintosh laryngoscopic intubation is a lifesaving procedure, but a difficult skill to learn. The Airtraq optical laryngoscope (AOL) is a novel intubation device with advantages over the direct laryngoscope for untrained personnel in a manikin study. We compared the effectiveness of AOL with Macintosh laryngoscope for tracheal intubation by novice personnel. ⋯ The AOL is a more effective instrument for tracheal intubation than Macintosh laryngoscope when used by novice personnel.

The effect of intravenous low dose ketamine for reducing postoperative sore throat.
This study was performed to evaluate the effectiveness of intravenous low dose ketamine for reducing the incidence and severity of postoperative sore throat (POST). ⋯ Intravenous injection of low dose ketamine was not effective for reducing POST.

Breakage of a thoracic epidural catheter during its removal -A case report-.
The breakage of an epidural catheter is a rare complication during the removal of a thoracic epidural catheter. There are many causes to breakage of an epidural catheter, such as the characteristics of the catheter itself, patient's factors (anatomy, position during insertion and removal of the catheter, and the BMI), and the difficulty of the procedure. ⋯ To prevent the catheter breakage during its removal, the catheter should be withdrawn without excessive tension. In addition, an understanding of the patient's anatomy is essential.

Prolonged paradoxical air embolism during intraoperative intestinal endoscopy confirmed by transesophageal echocardiography -A case report-.
Venous air embolism (VAE) during intestinal endoscopy is a rare complication. We report a case of cardiovascular collapse due to VAE confirmed by transesophageal echocardiography (TEE) during intraoperative intestinal endoscopy. ⋯ This case demonstrates that TEE can play an important role in diagnosing and managing an air embolism in anesthetized patients. In addition, this case demonstrates that PAEs may occur longer than expected after recovery from VAE-induced cardiovascular collapse.

Caudal analgesia reduces the sevoflurane requirement for LMA removal in anesthetized children.
An anesthetic state can reduce adverse airway reaction during laryngeal mask airway (LMA) removal in children. However, the anesthetic state has risks of upper airway obstruction or delayed emergence; so possibly less anesthetic depth is advisable. Caudal analgesia reduces the requirement of anesthetic agents for sedation or anesthesia; it is expected to reduce the sevoflurane requirement for LMA removal. Therefore, we determined the EC(50) of sevoflurane for LMA removal with caudal analgesia and compared that to the EC(50) without caudal analgesia. ⋯ Caudal analgesia significantly reduced the sevoflurane concentration for a smooth LMA removal in anesthetized children.
