Rad-87 and RRa are new acoustic monitoring devices which can monitor the respiratory rate. To our knowledge, no studies have reported the RRa sensor used in pediatric patients after surgery. We succeeded in measuring the respiratory rate with the RRa sensor in the Pediatric Intensive Care Unit(PICU). ⋯ Furthermore, RRa could count his respiratory rate, during transfer from the operating room to PICU. The patient was sedated with dexmedetomidine (0.28 microg . kg-1 . min-1) at PICU, and his respiratory rate was accurately measured with the RRa sensor. We hope that Rad-87 and RRa sensors will become useful for measuring the respiratory rate in pediatric patients in the future.

Randomized Controlled Trial Meta Analysis Comparative Study
[Airtraq for difficult airways: A meta-analysis of randomized controlled trials].
Increased evidence indicates that the Airtraq is useful for difficult tracheal intubations. The aim of this meta-analysis was to assess the efficacy of the Airtraq in difficult airways, comparing with that of Macintosh laryngoscopy. ⋯ There is considerable evidence that Airtraq has an advantage over Macintosh laryngoscope in difficult airways.

Pregabalin has been available in Japan since June 2010 for neuropathic pain. The adverse effects of pregabalin might be serious, and one must start at minimal doses and increase gradually to effective doses with enough explanation to patients. Pregabalin is a derivative of y-aminobutyric acid (GABA), but it has no effects on GABA receptors. ⋯ The effects of pregabalin is to bind alpha2delta-1 subunit and normalize the numbers of VGCCs at neuron surface and decreases neurotransmission, especially by excitatory amino acid. The descending facilitating serotonergic system from rostral ventromedial medulla may have effects on the occurrence and maintenance for the chronic pain. New drugs with less adverse effects may be developed.

Randomized Controlled Trial Meta Analysis Comparative Study
[Channeled videolaryngoscope: A meta-analysis of randomized controlled trials].
The aim of this meta-analysis was to assess the efficacy of the channeled videolaryngoscopes in routine tracheal intubation. ⋯ Compared to the Macintosh laryngoscopy, channeled videolaryngoscopy offers advantages for novice laryngoscopists, while these benefits are not seen with experts' hands in normal airways. Even with skillful hands, channeled videolaryngoscopy improves the successful first-attempt intubation in difficult intubations.

Case Reports
[Combined spinal-epidural anesthesia for caesarean section in a parturient with scoliosis].
An emergency caesarean section was performed in a 38-year-old parturient with pregnancy-induced hypertension at week 31 of gestation because of nonreassuring fetal status. A chest X-ray revealed mild spinal scoliosis. We attempted a combined spinal-epidural anesthesia in the parturient because the Cobb angle was only 28 degrees. ⋯ Analgesia was achieved from the T6 to S regions, and the caesarean section was completed uneventfully. A postoperative X-ray and computed tomography scan revealed that the rotation of the lumbar spine was so severe that the spaces between the laminae of the lumbar regions were shifted to the left and narrowed. Therefore, the puncture of the epidural and subarachnoid spaces was difficult, suggesting that the degree of lumbar spine rotation is more important than the thoracic spine curvature for successful epidural and spinal anesthesia in parturients with scoliosis.
