Flexible bronchoscopy (FB) is commonly performed by respiratory physicians for diagnostic as well as therapeutic purposes. However, bronchoscopy practices vary widely across India and worldwide. The three major respiratory organizations of the country supported a national-level expert group that formulated a comprehensive guideline document for FB based on a detailed appraisal of available evidence. These guidelines are an attempt to provide the bronchoscopist with the most scientifically sound as well as practical approach of bronchoscopy. It involved framing appropriate questions, review and critical appraisal of the relevant literature and reaching a recommendation by the expert groups. The guidelines cover major areas in basic bronchoscopy including (but not limited to), indications for procedure, patient preparation, various sampling procedures, bronchoscopy in the ICU setting, equipment care, and training issues. The target audience is respiratory physicians working in India and well as other parts of the world. It is hoped that this document would serve as a complete reference guide for all pulmonary physicians performing or desiring to learn the technique of flexible bronchoscopy.
Background:Although sepsis is one of the leading causes of mortality in hospitalized patients, information regarding early predictive factors for mortality and morbidity is limited.Materials and Methods:Patients fulfilling the Infectious Disease Society of America criteria of sepsis within the medical intensive care unit (ICU) were included over two years. Apart from baseline hematological, biochemical, and metabolic parameters, Acute Physiology and Chronic Health Evaluation II (APACHE II), Simplified Acute Physiology Score II and III (SAPS II and SAPS III), and Sequential Organ Function Assessment (SOFA) scores were calculated on day 1 of admission. Patients were followed till death or discharge from the ICU.Results:One hundred patients were enrolled over two years (54% males). The overall mortality was 53%, (69.5% in females, 38.8% in males (P < 0.01). Mortality was 65.7%, 55.7%, and 33.3% in patients with septic shock, severe sepsis, and sepsis, respectively. Patients who died were significantly older than the survivors (mean age, 57.37 ± 20.42 years and 44.29 ± 15.53 years respectively, P < 0.01). Nonsurvivors were significantly more anemic and had higher APACHE II, SAPS II, SAPS III, and SOFA scores. The presence of acute respiratory distress syndrome and renal dysfunction were associated with higher mortality (75% and 70.2%, respectively). There was no significant difference in the duration of mechanical ventilation or ICU stay between survivors and nonsurvivors. On multivariate analysis, significant predictors of mortality with odds ratio greater than 2 included the presence of anemia, SAPS II score greater than 35, SAPS III score greater than 47, and SOFA score greater than 6 at day 1 of admission.Conclusion:Several demographic and laboratory parameters as well as composite critical illness scoring systems are reliable early predictors of mortality in sepsis. A sepsis mortality prediction formula (AIIMS Sepsis Score) based on SAPS II, SAPS III, and SOFA scores and hemoglobin has greater predictive power than these scoring methods individually. Routine use of critical illness scoring systems and a composite mortality prediction formula may provide useful early prognostic information in sepsis/severe sepsis.
Background: A systematic assessment of comprehensive clinical outcomes after various therapeutic procedures for malignant central airway obstruction (CAO) is lacking. Methods: Patients with symptomatic malignant CAO undergoing various therapeutic bronchoscopy procedures were assessed for symptomatic and functional improvement using the Speiser Score, spirometry, 6-minute walk distance (6MWD), and St. George Respiratory Questionnaire (SGRQ) up to 3 months after the procedures. Results: A total of 83 intervention procedures were performed in 65 patients, comprising 43 (66.2%) male individuals [overall mean age, 52.4; SD, 15.4 y]. The majority of these (92.3%) was done using rigid bronchoscope under general anesthesia. Airway stenting was the most common intervention performed (56.6%), followed by mechanical debulking (26.5%), cryodebulking (6%), electrosurgical removal (4.8%), balloon dilatation (3.6%), and laser ablation (2.4%). A total of 15 complications (18.1%) were noted. Of these, 8 (53.3%) were early complications and 7 (46.7%) were late complications. Early complications included airway bleeding, hypoxia, vocal cord injury, laryngeal injury, and pneumothorax. Late complications included significant granulation tissue formation in metallic stents and lung collapse because of mucus plug. The survival rates at 4, 8, and 12 weeks were 83%, 70.7%, and 66.1%, respectively. Significant improvement was observed in dyspnea, cough, Speiser Score, 6MWD, forced expiratory volume in 1 s, forced vital capacity, and SGRQ scores at 48 hours, 4 weeks, and at 12 weeks after the procedures and no procedure-related mortality occurred. Conclusion: Various therapeutic bronchoscopic interventions, including combined modalities, provide rapid and sustained improvements in symptoms, respiratory status, exercise capacity, and quality of life in malignant CAO and have a good safety profile.
