Comparison of the Airtraq and the Macintosh laryngoscope for double-lumen tube intubation: a randomised clinical trial.

CONTEXT: The Airtraq is a disposable optical laryngoscope that is available in a double-lumen tube version. Inserting a double-lumen tube is generally more difficult compared to conventional endotracheal intubation, mainly due to its configuration. OBJECTIVE: The aim of this study was to compare the Airtraq with the Macintosh laryngoscope for intubation with a double-lumen tube in patients undergoing elective thoracic surgery. The main outcome was time needed for successful intubation. DESIGN: Prospective, randomised clinical trial. SETTING: A single centre, University Hospital of Würzburg, Germany, between July 2009 and June 2011. PATIENTS: After a scout laryngoscopy with a Macintosh laryngoscope, 60 adult patients were intubated by an anaesthesiologist with either an Airtraq (n = 30) or a Macintosh laryngoscope (n = 30). MAIN OUTCOME MEASURES: The time needed for correct intubation, checked by flexible bronchoscopy, was recorded. The intubation difficulty scale (IDS) and Cormack and Lehane grade were noted. Haemodynamic variables and any evidence of oropharyngeal trauma were documented as well as postoperative sore throat, hoarseness and dysphagia. RESULTS: The mean time needed for correct intubation was 20.1 ± 16.5 s in the Airtraq group and 17.5 ± 10 s in the Macintosh group (P = 0.86). All intubations in both groups had an IDS less than 4. The Cormack and Lehane grade was I in all 30 patients in the Airtraq group; in the Macintosh group, it was I and II in 17 and 13 patients, respectively. The incidence of hoarseness was significantly higher in the Airtraq group 24 h postoperatively (P = 0.01). CONCLUSION: There was no significant difference between the Airtraq and the Macintosh laryngoscopes regarding the time needed to insert a double-lumen tube during elective thoracic surgery. Only subtle enhancement of visualisation and a higher incidence of hoarseness were observed in the Airtraq group. The Airtraq device did not result in superior patient safety in this setting.

Interdisciplinary Screening, Diagnosis, Therapy and Follow-up of Breast Cancer. Guideline of the DGGG and the DKG (S3-Level, AWMF Registry Number 032/045OL, December 2017) - Part 1 with Recommendations for the Screening, Diagnosis and Therapy of Breast Cancer.

Purpose The aim of this official guideline coordinated and published by the German Society for Gynecology and Obstetrics (DGGG) and the German Cancer Society (DKG) was to optimize the screening, diagnosis, therapy and follow-up care of breast cancer. Methods The process of updating the S3 guideline dating from 2012 was based on the adaptation of identified source guidelines which were combined with reviews of evidence compiled using PICO (Patients/Interventions/Control/Outcome) questions and the results of a systematic search of literature databases and the selection and evaluation of the identified literature. The interdisciplinary working groups took the identified materials as their starting point to develop recommendations and statements which were modified and graded in a structured consensus procedure. Recommendations Part 1 of this short version of the guideline presents recommendations for the screening, diagnosis and follow-up care of breast cancer. The importance of mammography for screening is confirmed in this updated version of the guideline and forms the basis for all screening. In addition to the conventional methods used to diagnose breast cancer, computed tomography (CT) is recommended for staging in women with a higher risk of recurrence. The follow-up concept includes suggested intervals between physical, ultrasound and mammography examinations, additional high-tech diagnostic procedures, and the determination of tumor markers for the evaluation of metastatic disease.

Interdisciplinary Screening, Diagnosis, Therapy and Follow-up of Breast Cancer. Guideline of the DGGG and the DKG (S3-Level, AWMF Registry Number 032/045OL, December 2017) - Part 2 with Recommendations for the Therapy of Primary, Recurrent and Advanced Breast Cancer.

Purpose The aim of this official guideline coordinated and published by the German Society for Gynecology and Obstetrics (DGGG) and the German Cancer Society (DKG) was to optimize the screening, diagnosis, therapy and follow-up care of breast cancer. Method The process of updating the S3 guideline published in 2012 was based on the adaptation of identified source guidelines. They were combined with reviews of evidence compiled using PICO (Patients/Interventions/Control/Outcome) questions and with the results of a systematic search of literature databases followed by the selection and evaluation of the identified literature. The interdisciplinary working groups took the identified materials as their starting point and used them to develop suggestions for recommendations and statements, which were then modified and graded in a structured consensus process procedure. Recommendations Part 2 of this short version of the guideline presents recommendations for the therapy of primary, recurrent and metastatic breast cancer. Loco-regional therapies are de-escalated in the current guideline. In addition to reducing the safety margins for surgical procedures, the guideline also recommends reducing the radicality of axillary surgery. The choice and extent of systemic therapy depends on the respective tumor biology. New substances are becoming available, particularly to treat metastatic breast cancer.
