Bronchoalveolar lavage (BAL) involves instilling sterile saline into the distal airways and retrieving the fluid for sampling. It is a crucial diagnostic tool for animals with respiratory issues. However, BAL carries risks of respiratory symptom exacerbation during or after the procedure due to its invasive nature, as fluid is introduced into the gas-exchanging alveoli.
Traditionally, BAL is performed via 'blind lavage,' where the affected side is positioned downward, relying on gravity to direct fluid into the target lung lobe. Recent advancements in bronchoscopy allow for more targeted sampling, improving fluid recovery rates and sample depth. Studies show that bronchoscopy-assisted BAL offers better fluid retrieval and deeper sample collection compared to the blind method.
Whether performing traditional BAL or bronchoscopy-assisted BAL, airway maintenance is recommended. The purpose of airway maintenance is to ensure continuous oxygen supply via endotracheal intubation or a laryngeal mask and to provide positive pressure ventilation if spontaneous breathing ceases. Research indicates a significant difference in post-procedure complications and mortality rates depending on whether airway maintenance is employed. In the author's experience, performing BAL without airway maintenance often results in significant hypoxemia, making recovery post-anesthesia more challenging. However, with airway maintenance and bronchoscopy, animals maintain better oxygenation during BAL and have smoother recovery.
Therefore, even in traditional BAL without bronchoscopy, it is advisable to use airway maintenance with an adapter for added safety.
