Case ReportsUse of the ETView Tracheoscopic Ventilation Tube in airway management of a patient with unanticipated difficult bag-mask ventilation.
The management of unanticipated difficult airway is a clinical challenge to anesthesiologists. The ETView Tracheoscopic Ventilation Tube (ETView), which is capable of real-time video imaging of the airway without needing additional equipment, may provide a promising settlement for the cases. Here, we reported a successful management of unanticipated difficult bag-mask ventilation airway with the ETView. More importantly, we successfully maintained oxygenation by modifying its injection and suction port.

Multicenter Study Observational StudySocioeconomic value of intervention for chronic pain.
The purpose of this study was to examine the cost-effectiveness of pain treatments in two pain centers in Japan. ⋯ Based on our results, the EQ-5D is reliable for evaluating chronic pain in patients. The medico-economic balance was appropriate for all treatments provided in two comprehensive pain centers in Japan.

Observational StudyEpidural pressure changes following caudal blockade: a prospective, observational study.
Recent case reports raise the question as to whether anesthetic agents injected into the epidural space could lead to a 'compartment syndrome' and neurovascular sequelae. Single-shot caudal epidural anesthesia has been established as a safe technique, but changes in pressure in the caudal epidural space have not been described. Our aim was to study pressure changes to provide preliminary information for future studies design. ⋯ Following the administration of the local anesthetic into the caudal epidural space, there was a marked, but transient, increase in the pressure within the epidural space. It appears unlikely that a slow epidural catheter infusion could lead to a sustained increase in epidural pressure.

Case ReportsUnintentional epidural placement of a thoracic paravertebral catheter inserted using an ultrasound-guided technique: a case report.
This is the first case report describing the epidural misplacement of an infusion catheter, which was intended to be located in the thoracic paravertebral space using an ultrasound-guided technique. The patient was a 57-year-old female undergoing a laparoscopy-assisted left partial nephrectomy. Before surgery, a Tuohy needle was inserted into the paravertebral space at the left ninth intercostal space using an in-plane transverse ultrasound-guided approach in the lateral-to-medial direction. ⋯ The motor dysfunction in the lower extremities lasted 7 h, and the sensory block lasted 13.5 h. Postoperative radiologic confirmation of the catheter position concomitant with the spread of radiopaque dye revealed that the tip of the catheter was lying in the epidural space. Unless precise attention is paid to detection of the catheter tip location, a thoracic paravertebral catheter can enter into the epidural space even under ultrasound guidance.
