[McGRATH® MAC Is Useful to Learn Tracheal Intubation Using a Macintosh Laryngoscope].

Background: Learning tracheal intubation using a Macintosh laryngoscope (McL) is important although video laryngoscope is becoming popular. The purpose of this study was to compare the usefulness as a training device for intubation technique using McL with three devices; McGRATH® MAC (MAC), Airwayscope® (AWS) and McL.

Methods: In this prospective study, 60 nurses not experienced in tracheal intubation were randomly assigned to MAC, AWS, and McL groups (each group: n=20), and 10 times of practice using each device were carried out.

[A patient with a huge posterior mediastinal tumor and ST-segment depression in electrocardiogram].

A 68-year-old woman had felt a chest and back pain for 3 months. Gradually her symptom became aggravated, and she felt severe dyspnea in supine position and dysphagia combined with superior vena cava syndrome. A huge posterior mediastinal tumor was revealed and her esophagus was severely narrowed on the chest MRI.

[Relationships between hemostatic variables and delay of surgical repair of femoral neck fracture in elderly patients].

Background: This study was conducted to clarify the preoperative risk of thrombosis in elderly patients with femoral neck fracture by determining the relationships between hemostatic variables and time from injury until surgical repair.

Methods: Thirty-four patients over 70 years of age with femoral neck fracture were assigned to the following three groups according to the delay of surgical repair: usual operation group (within 3 days), delayed operation group (from 4 to 7 days) and much delayed operation group (more than 8 days). Hemostatic variables including molecular markers were determined before surgical repair.
