[Recommendations for sedation during flexible bronchoscopy]

Flexible bronchoscopy is a standard examination today and is conducted not only in nearly every hospital but also in privately owned practices. The vast majority of patients want sedation for this examination. Such a procedure is nearly always necessary in complex and interventional procedures, irrespective of the patient's wish. The recommendation at hand to use sedation measures for flexible bronchoscopy is based on the results of numerous clinical studies and also takes account of individual experiences in this area. The structural and procedural requirements and the requirements for staff training are defined and should describe the minimum standard when it comes to conducting a bronchoscopy under sedation. Furthermore the drugs recommended for sedation are discussed and their methods of application shown. Finally the recommendations also include suggestions for patient clarification, monitoring and discharge. They should provide the examiner with concrete operating options and therefore above all increase patient safety.

[Implementing in-patient smoking cessation interventions. Basic characteristics of smoking patients in a lung health department]

BACKGROUND

Hospitals have a unique key role in promoting smoking cessation. However, cessation interventions are uncommon in clinical routine despite their proven effectiveness. For planning a tailored intervention for hospitalised patients we examined the characteristics of smokers in our department for lung diseases.

METHODS AND PATIENTS

From July to September 2009 we evaluated the smoking status of all admitted patients. The smoking status was validated by measuring the CO-Hb. Smokers admitted for the first time on one of our regular wards received a comprehensive questionnaire. Patients with a duration of stay of 2 days or less and patients with substantial cognitive or linguistic limitations were excluded. Clinical data was collected from the participating smokers.

RESULTS

25% of all admitted patients were smokers. The participation rate was almost 90% of the eligible smokers. Our questionnaire was very well accepted und provided multitude helpful information for a following cessation counselling. Up to 3 or 4 smokers per day should be anticipated for a cessation intervention at an 80-bed-hospital. At least one counselling contact could be enabled. Although 75% of participants had experienced at least one unsuccessful quit attempt, only a minority used any support or help for cessation so far.

CONCLUSIONS

Specific questionnaires to evaluate the smoking history of patients in hospitals are very suitable and facilitate a subsequent bedside-counseling. To come up with their key role in promoting smoking cessation more hospitals as yet should implement cessation interventions.

Cryobiopsy increases the diagnostic yield of endobronchial biopsy: a multicentre trial

Forceps, brushes or needles are currently the standard tools used during flexible bronchoscopy when diagnosing endobronchial malignancies. The new biopsy technique of cryobiopsy appears to provide better diagnostic samples. The aim of this study was to evaluate cryobiopsy over conventional endobronchial sampling. A total of 600 patients in eight centres with suspected endobronchial tumours were included in a prospective, randomised, single-blinded multicentre study. Patients were randomised to either sampling using forceps or the cryoprobe. After obtaining biopsy samples, a blinded histological evaluation was performed. According to the definitive clinical diagnosis, the diagnostic yield for malignancy was evaluated by a Chi-squared test. A total of 593 patients were randomised, of whom 563 had a final diagnosis of cancer. 281 patients were randomised to receive endobronchial biopsies using forceps and 282 had biopsies performed using a flexible cryoprobe. A definitive diagnosis was achieved in 85.1% of patients randomised to conventional forceps biopsy and 95.0% of patients who underwent cryobiopsy (p<0.001). Importantly, there was no difference in the incidence of significant bleeding. Endobronchial cryobiopsy is a safe technique with superior diagnostic yield in comparison with conventional forceps biopsy.
