We report a 61-year-old woman (weight 49 kg, height 156 cm) with Kugelberg-Welander disease who was scheduled for bilateral mastectomy under general anesthesia. We administered rocuronium 10 mg (0.20 mg x kg(-1)) for tracheal intubation. After 80 min, train-of-four ratio (TOFR) was 46%. ⋯ After 4 min, TOFR became above 90%, and the patient was extubated. There was no respiratory distress, muscle weakness, or neurologic untoward event after the use of sugammadex in the postoperative period. Sugammadex was effective in reversing rocuronium induced neuromuscular block in a patient with Kugelberg-Welander disease.

The use of positive end-expiratory pressure (PEEP) is a practical intervention to improve oxygenation during anesthetic management; however, the underlying mechanisms have not been elucidated. ⋯ These results suggest that the mechanisms for improved oxygenation by PEEP under sevoflurane anesthesia are different from those under propofol anesthesia. The improved oxygenation after the application of PEEP under sevoflurane anesthesia is mainly due to reduction of atelectasis, whereas reduction of atelectasis as well as reduction of intrapulmonary shunt is associated with the improved oxygenation after the application of PEEP under propofol anesthesia.

A 60-year-old female with anti-phospholipid syndrome underwent amputation of her left lower limb. She had had a history of cerebral infarction, cerebral hemorrhage, coagulation abnormalities, thrombocytopenia, and pneumothorax, and just recovered from disseminated intravascular coagulation. After intravenous fentanyl 25 microg, ultrasound-guided sciatic, femoral and lateral femoral cutaneous nerve blocks were performed. ⋯ For femoral nerve block, a catheter was inserted and ropivacaine was infused at 4 ml x hr(-1) after surgery. Amputation at the left thigh was successfully performed and postoperative course was uneventful. The sciatic, femoral and lateral femoral cutaneous nerve blocks were useful for amputation of a patient with severe coagulopathy by anti-phospholipid syndrome.

In most cases, an endotracheal tube (ETT) enters the right bronchus due to anatomical features of the trachea. The Parker Flex-Tip Tube (Parker tube) has a centered and tapered tip with a posterior facing bevel. Here, we report a case of accidental left bronchial intubation that may be associated with the tip design of the Parker tube. ⋯ To test this hypothesis, we conducted a simulation study using a standard airway mannequin. Intubation with a standard left-beveled ETT resulted in right bronchial intubation in all 20 trials, while 4 of the 20 Parker tubes entered the left mainstem bronchus. This investigation suggests that unintentional left bronchus intubation of the Parker tube may occur in the ordinary clinical setting if the tube is advanced beyond the carina.

Gum Elastic Bougie (GEB) was originally introduced into clinical practice in 1949 by Sir Robert Macintosh. British anesthesiologists choose this tracheal tube introducer than the malleable stylet to facilitate difficult intubation. However, the bougie may not always be used in an optimal manner in Japan. ⋯ GEB is superior to the stylet for a difficult intubation. It is easy to use, portable, and of relatively low cost. We believe that the GEB is useful in patients with and without difficult airways.
