Severe Pneumonia Management and Bronchoalveolar Lavage Efficacy in Yunnan's Ethnic Minorities
Abstract
: This investigation evaluates the therapeutic effectiveness of bronchoalveolar lavage (BAL) for severe pneumonia in ethnic minority groups within the Pu'er district. We conducted a prospective, randomized controlled trial involving 68 patients diagnosed with severe pneumonia, assigning 37 to the treatment cohort and 31 to the control cohort. Patients in the treatment cohort underwent BAL, whereas their counterparts received standard care. Outcomes measured were the persistence of clinical symptoms, hospital stay duration, healthcare costs, and hematological markers including leukocyte count, procalcitonin (PCT), and arterial blood gases. Results indicated that the treatment cohort benefitted from a notable reduction in fever, cough, pulmonary rales, and antibiotic administration durations compared to the control (p<0.05). Furthermore, they experienced expedited symptom resolution and incurred lower hospitalization expenses (p<0.05). Arterial blood gas analyses revealed that the treated cohort's post-therapeutic oxygen partial pressures and oxygenation indices were substantially elevated (p<0.05). Although transient supraventricular tachycardia and dips in oxygen saturation were observed, these were not statistically significant (p=0.497). The application of BAL demonstrated pronounced clinical improvements, notably in pulmonary function and in diminishing the duration and cost of hospital care, underscoring its viability and safety with adequate monitoring. The findings…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 68 participants or records.
