Previous reports indicate that Prader-Willi syndrome may present various problems during anesthesia and the perioperative period. We retrospectively investigated anesthesia records of 10 patients (2 adults and 8 children) who were diagnosed to have Prader-Willi syndrome, and who had an operation under anesthesia. Three patients had small mouths, small jaws or both. ⋯ Difficult tracheal intubation occurred in one patient. No other major problems occurred. We conclude that the incidence of problems during anesthesia and postoperative period in patients with Prader-Willi syndrome would be less than previously considered.

There is an increasing number of patients scheduled for abdominal aortic aneurysm resection in whom epidural anesthesia cannot be performed because of concomitant antiplatelet/anticoagulant therapy. Instead of epidural anesthesia for postoperative analgesia in such patients it is possible to use repeated bilateral subcostal transversus abdominis plane (TAP) blocks. ⋯ These findings suggest that repeated bilateral subcostal TAP blocks with 0.2% lidocaine performed via 18-gauge intravenous catheters provide good postoperative analgesia after abdominal aortic aneurysm resection.

Case Reports
[Awake insertion of i-gel under dexmedetomidine sedation in a patient with severe obstructive sleep apnea syndrome].
We report a successful awake insertion of the i-gel supraglottic airway device under dexmedetomidine (DEX) sedation in a patient with severe obstructive sleep apnea syndrome and symptomatic angina. A 71-year-old man was scheduled for open stoma closure under general anesthesia. Given the patient's history of difficult mask ventilation during anesthesia for resection of rectal cancer, we decided to perform awake i-gel insertion under DEX sedation and regional anesthesia with lidocaine. ⋯ We also performed transversus abdominis plane block and rectus sheath block with ropivacaine, as severe respiratory suppression due to continuous intravenous fentanyl infusion had been observed in the previous operation. No vital sign change or respiratory suppression was noted upon recovery from general anesthesia. Awake insertion of a supraglottic airway device, such as i-gel, under DEX sedation can be effective for airway management in patients with severe obstructive sleep apnea syndrome.

Case Reports
[A case of prolongation of rocuronium neuromuscular blockade in a pregnant patient receiving magnesium].
A 35-year-old pregnant female with systemic lupus erythematosus and lupus nephritis underwent emergency cesarean section at 24 weeks of gestation under general anesthesia. The patient had received magnesium sulfate with a diagnosis of pregnancy-induced hypertension since 20 weeks of gestation. Anesthesia was induced with thiopental 3.5 mg x kg(-1) and tracheal intubation was facilitated by administration of rocuronium 1.0 mg x kg(-1). ⋯ After operation, no twitch was noted on the ulnar nerve TOF monitor. The TOF returned to 4/4 at postoperative 11 hours and the patient was extubated uneventfully. When rocuronium is used to facilitate general endotracheal anesthesia in a patient for emergency cesarean delivery, it is important to recognize that magnesium may prolong neuromuscular block significantly.

This article introduces the equipment used for epiduroscopy and describes its indications, procedures for use, treatment outcomes, the potential complications and future developments. Epiduroscopy is used in the treatment and diagnosis of intractable low back and leg pain in patients in whom nerve block is not efficacious and when pain recurs after operation. The characteristics of epiduroscopy are that it is: 1) safe and less invasive; 2) used for endoscopic washing of the epidural space and fluoroscopic X-ray; 3) it allows injection of an agent into the lesion; and 4) it results in no change in the normal lumbar structure after operation. Epiduroscopy is expected to provide successful outcomes for many patients with intractable low back and leg pain through further improvements in equipment related to epiduroscopy, advances in technology, the accumulation of data regarding its efficacy and safety, and the coverage of treatment by insurance.
