Introduction

  • Washing of cells from bronchoalveoli allows cytological diagnosis of respiratory pathology.

Uses

Advantages

  • Relatively rapid procedure.
  • Minimal risk above that of anesthetic.
  • Endoscopy allows visualization of respiratory tract.
  • Quality of cytological samples is generally high.

Disadvantages

  • Requires general anesthetic.
  • Requires rigid bronchoscope to obtain uncontaminated sample from alveoli.
  • technique limited by length of bronchoscope in large animals and diameter in small animals.
  • Requires additional training and expertise.

Prognosis

  • Animals with severe tracheal sensitivity prior to the procedure may experience worsening of cough in the immediate period of procedure. This can be prevented by instilling 0.5-1.0 cc of 1% lidocaine through the biopsy channel of the bronchoscope at the very end of the procedure to reduce the cough reflex.
