Less postoperative sore throat after nasotracheal intubation using a fiberoptic bronchoscope than using a Macintosh laryngoscope: A double-blind, randomized, controlled study.

Study Objective: To evaluate whether nasotracheal intubation using a fiberoptic bronchoscope reduces postoperative sore throat.

Design: Prospective, double-blinded, randomized, and controlled study.

Setting: Postoperative areas and surgical ward of a university hospital.

Evaluation of bias in predicted and measured propofol concentrations during target-controlled infusions in obese Japanese patients: an open-label comparative study.

Background: Target-controlled infusions (TCIs) of propofol are commonly used for general anaesthesia. The Marsh model pharmacokinetic parameter set incorporated in TCI devices for propofol could increase bias when used in obese patients.

Objective: The purpose of this study was to assess the optimal predicted blood concentration (Cp) of 4.

Incidence of cannot intubate-cannot ventilate (CICV): results of a 3-year retrospective multicenter clinical study in a network of university hospitals.

Purpose: The purpose of this study was to investigate the incidence of cannot intubate-cannot ventilate (CICV) during general anesthesia during a 3-year period in a network of university hospitals and to evaluate the events related to it.

Methods: A retrospective multicenter questionnaire survey of CICV, based on medical record review, was conducted over a 3-year period (January 2010-December 2012) in Hokkaido, Japan. All cases were assessed in terms of the suspected risk factors of CICV, the clinical course during anesthesia, and the prognosis.

[Anesthetic management in a patient with spinal progressive muscle atrophy and compromised severe restrictive respiratory dysfunction].

Spinal progressive muscular atrophy (SPMA) is a rare lower motor neuron disease in which anesthetic management is often difficult as a result of muscle weakness and hypersensitivity to neuromuscular blocking agents. A 43-year-old female patient with SPMA was scheduled to undergo laparotomy for ovarian teratoma. Her vital capacity was only 530 ml and % volume capacity was 22.

Utility of longitudinal paramedian view of ultrasound imaging for middle thoracic epidural anesthesia in children.

Purpose: The risk of nerve injury for pediatric thoracic epidural block increases stress for anesthesiologists. The purpose of this study was to investigate the usefulness of longitudinal ultrasound imaging for thoracic epidural block (T5-T6 or T6-T7) in anesthetized children scheduled for the Nuss procedure.

Methods: Neuraxial structure in the longitudinal paramedian section was observed using ultrasound imaging before epidural puncture (US group, n = 10).

Ultrasound-guided cervical nerve root block: spread of solution and clinical effect.

Objectives: We investigated the clinical effects and accuracy of ultrasound-guided cervical nerve root block. Additionally, spinal level and spread of injected solution were confirmed by anatomic dissection of fresh cadavers. DESIGN SETTING, PATIENTS, AND INTERVENTIONS: Twelve patients diagnosed with mono-radiculopathy between C5-7 underwent ultrasound-guided nerve root block.

Usefulness of Endoflex endotracheal tube for oral and nasal tracheal intubations.

Background And Objectives: We investigated the usefulness of an Endoflex tracheal tube, the tip of which can be bent forward by pulling on a wire held in the hand, for oral and nasal endotracheal intubations without a stylet, in comparison with tracheal intubation using a conventional endotracheal tube and a stylet/Magill forceps.

Methods: The study participants comprised 40 patients for oral intubation and 20 patients for nasal intubation. Each group was then divided into control and Endoflex subgroups.
