Case ReportsA case of congenital central hypoventilation syndrome.
We encountered a 2-year-old female infant with congenital central hypoventilation syndrome (CCHS) who underwent an abdominal operation for strangulated ileus. Prior to the surgery, at home, the infant had been receiving non-invasive positive-pressure ventilation (NPPV) support only during sleep. However, after postoperative extubation, the blood oxygen saturation (SpO(2)) decreased to approximately 90 % with NPPV during sleep alone, necessitating the use of biphasic cuirass ventilation (BCV) along with NPPV for 2 days. ⋯ No relationship was found between the tidal volume and the respiratory rate. Various modalities have been used for the treatment of CCHS (tracheotomy, NPPV, and diaphragmatic pacing). Treatment of these patients in the ICU should be tailored to the needs of individual patients and their families.

Clinical trial of a method for confirming the effects of spinal anesthesia in patients with spinal cord injury.
In this case series study, we prospectively examined whether it might be possible to check the effect of spinal anesthesia (SA), based on the disappearance of lower extremity reflexes and spasticity, in patients with spinal cord injury (SCI), in whom the effect cannot be confirmed by the pinprick test or by using the Bromage scale. In 40 patients with chronic, clinically complete cervical SCI who were scheduled to receive SA, pre-anesthetic examination revealed that the Babinski sign, patellar tendon reflex, and spasticity (assessed using the Ashworth scale) were all positive in 31 patients, while two of these three pre-anesthetic assessment parameters were positive in eight patients. ⋯ Our results suggested that the effect of SA can be confirmed by the disappearance of the Babinski sign and patellar tendon reflex and loss of spasticity in most patients with complete cervical SCI, although determination of the level of the block is difficult. In conclusion, loss of the Babinski sign, patellar tendon reflex, and spasticity might be useful for checking the effect of SA in cervical SCI patients.

Case ReportsNon-surgical therapy for bilateral glossopharyngeal neuralgia caused by Eagle's syndrome, diagnosed by three-dimensional computed tomography: a case report.
Eagle's syndrome is an uncommon sequela of elongation of the styloid process. Symptoms include recurrent throat pain and anterolateral neck pain, with referred pain to the ear. We report a 65-year-old man who presented with bilateral glossopharyngeal neuralgia. ⋯ Eagle's syndrome. Because the patient refused surgical treatment, conservative therapy was selected. Oral gabapentin, stellate ganglion block, and 8 % lidocaine spray on the tonsillar branches of the glossopharyngeal nerve resulted in complete resolution of the paroxysms of pain in approximately 3 weeks.

Pharmacokinetics and safety of 6 % hydroxyethyl starch 130/0.4 in healthy male volunteers of Japanese ethnicity after single infusion of 500 ml solution.
This phase I study was performed in volunteers of Japanese ethnicity to compare pharmacokinetic data after infusion of 6 % hydroxyethyl starch (HES) 130/0.4 with historical data of Caucasians. ⋯ Single administration of a 500 ml solution of 6 % HES 130/0.4 was confirmed to be safe and tolerable in healthy male Japanese subjects. A rapid renal excretion was observed within 24 h after drug administration, accounting for 96 % of the total amount excreted. A comparison with pharmacokinetic data derived from Caucasians did not reveal significant differences to Japanese and confirmed the good tolerability in both ethnic groups.

The usefulness of near-infrared spectroscopy in the anesthetic management of endovascular aortic aneurysm repair.
Near-infrared spectroscopy (NIRS) may be a useful method for monitoring the regional oxygen saturation (rSO(2)) of the lower extremity during endovascular aortic repair. Eighteen patients with thoracic descending and/or abdominal aortic aneurysm were enrolled in this study. NIRS probes were placed bilaterally on the calves. ⋯ In the 2 other patients, however, mrSO(2) did not recover after the first declamping, because of femoral artery dissection. After additional repair, mrSO(2) recovered quickly to the control value. These data suggested NIRS may objectively and quantitatively reflect oxygenation of the lower extremities, and may indicate an ischemic event that needs additional repair during endovascular aortic repair.
