Bronchoscopy is a procedure that is likely to provoke anxiety as the patient is surrounded by monitoring and bronchoscopy equipment, and care is administered by strangers who perform intimate, invasive, and sometimes, painful procedures. Sedation is needed, therefore, to allay anxiety and reduce stress, improve patient comfort and co-operation, provide amnesia and facilitate the bronchoscopic procedure. In this review we try to summarize the current knowledge on currently used sedation protocols with special reference to the commonly used pharmacological agents. We believe sedation should be used routinely in fiberoptic bronchoscopy in order to achieve a safe and pleasant procedure for both the patient and the pulmonologist.

Role of spirometric and arterial gas data in predicting pulmonary complications after abdominal surgery.
The aim of this study was to evaluate the predictive value of preoperative spirometric and arterial gas data on severe pulmonary complications (PC) after elective abdominal surgery. We retrospectively studied 480 patients, 254 males and 226 females, mean (SD) age 63 (11) years, at risk for PC according to standardized criteria, who underwent laparotomy for resection of gallbladder for gallstones (44% of patients), resection of colon, rectum or stomach for malignant tumours (37%), and other abdominal surgery (19%). The overall incidence of postoperative PC was 18%. ⋯ Ischaemic heart disease (OR=3.44, 95%CI=1.08-10.93), operation for malignant tumours (OR=3.24, 95%CI=1.75-6.00) and age (OR=1.04, 95%CI=1.00-1.08) were also independent predictors of PC. Patients with moderate-to-severe airway obstruction combined with hypoxaemia had a significant higher risk of PC in comparison with patients with a normal respiratory pattern. Taking into account age, type of operation, and comorbidity, a preoperative respiratory functional assessment could be useful in identifying an increased risk of major PC in selected patients.

Stages of disease severity and factors that affect the health status of patients with chronic obstructive pulmonary disease.
We hypothesized that the factors which may influence health status would differ in patients at different disease stages of chronic obstructive pulmonary disease (COPD). The present study investigated how impairments in health status were distributed in male patients at each disease stage according to the British Thoracic Society (BTS) guidelines, and analysed the contribution of the clinical indices, the dyspnoea rating and the psychological status to the health status of patients at the three disease stages of COPD. ⋯ The disease staging proposed by the BTS guidelines can separate patients with COPD according to impairments in their health status. Furthermore, the factors that influence health status differed in patients at the three disease stages. Our findings support the boundaries used in disease staging and some recommendations from the BTS guidelines.

Randomized Controlled Trial Clinical TrialA randomized controlled evaluation of specialist nurse education following accident and emergency department attendance for acute asthma.
We investigated whether hospital-based specialist asthma nurses improved recognition and self-treatment of asthma episodes by patients followed up after attending accident and emergency departments (A&E) for asthma exacerbations. We carried out a randomized prospective controlled trial of adult asthma self-management, following a hospital outpatient nurse consultation in two outer-London District General Hospitals (secondary care centres). The study included 211 adults, over 18 years old (mean age 40 years) who attended for asthma in two accident and emergency departments over 13 months. ⋯ Intervention patients had fewer episodes away from work in the first (0.34 vs. 0.54, P = 0.08) and the second 3 months (0.25 vs. 0.30, NS) than the controls. Over 80% of the patients records were audited by their general practitioners; the active group had less routine consultations with the doctor (P = 0.03) and practice nurse (P = 0.03), less consultations for uncontrolled episodes (P = 0.06) and less hospital visits (NS) than the controls. Hospital-based specialist nurses reduced asthma morbidity by improving patient self-management behaviour in acute attacks leading to reduced symptoms, improved lung function, less time off work and fewer consultations with health professionals.
