Central venous catheterization using the Seldinger technique is a well known and often used method. On the other hand, there are also well known complications by needle puncture or by indwelling catheter, there are few reports about a guide wire which got hung up around the tricuspid valve. We report a case in which a guide wire got hung up to the chordae tendineae of the tricuspid valve. ⋯ There are many reports of the complication by the central venepuncture, but there are few reports about the guide wire which was entrapped in the vicinity of a tricuspid valve. The tip of the guide wire in this case was bent excessively, but the cause of the damage did not become clear by investigation. When a guide wire became hard to withdraw, we should never withdraw a guide wire blindly, but should search a cause and we should use the material which was matched with the cause.

In the cases in which the flexibility of the patient's neck is limited, it is often difficult to achieve intubation. Fiberoptic intubation has been chosen for patients with arthroses. However, as it requires techniques, it has been difficult for inexperienced anesthesiologists. ⋯ Awake intubation using AirWay Scope for patients with cervical spinal diseases is a safe and useful anesthesia method. As dexmedetomidine causes no respiratory depression and can expect cooperation from patients, it may give safe and efficient sedation in awake intubation cases.

Case 1: A 41-year-old woman was scheduled for pinning of fractured finger and repair of a ligamentum. Preoperative problems did not exist except mandibular hypoplasia. General anesthesia was induced and Cormack classification was grade III in laryngeal view by laryngoscope and we tried a new videolaryngoscope PENTAX-AirWay Scope (AWS). ⋯ Ten minutes were needed to finish intubation due to difficult airway (Cormack classification grade III) when free latissimus dorsi flap reconstruction was perfomed two month before. Hence, AWS using a bronchofiberscope procedure was tried first and 39 seconds were needed to intubate. We concluded that AWS using bronchofiberscope procedure was useful for patients with difficult airway, though two anesthesiologist, one keeping AWS and the other using a bronchofiberscope, were needed.

Recently there are growing number of patients suffering from the abdominal aortic aneurysm (AAA), and we have many occasions to anesthetize these patients under coagulation therapy as well. Moreover, the risk of epidural hematoma increases when the operation of the AAA is performed with epidural technique because the operation is usually done with perioperative heparinization. For these reasons, we investigated the current situations of clinical practice in Japan in terms of the epidural anesthesia for AAA surgeries. ⋯ This investigation clarified the current situations of the clinical practice in Japan of the use of epidural anesthesia for AAA surgeries.

Sore throat and hoarseness are common postoperative complications in patients who undergo tracheal intubation. In this study, we evaluated the severity of postoperative sore throat and the incidence of hoarseness in 60 patients after tracheal intubation. ⋯ In this study, VAS scores at the end of anesthesia and the next day were both significantly higher in the lubricated group than in others. Furthermore, there is no significant difference in VAS between the sprayed group and the no-intervention group. These data suggest that lidocaine jelly lubrication to the endotracheal tube reinforces the severity of sore throat. On the other hand, there was no significant difference in VAS between the sprayed group and the no-intervention group. This suggests that lidocaine sprayed to the trachea does not reduce postoperative sore throat.
