Bronchoscopic Electrocautery Versus Adrenaline and Cold Saline Instillation for Prophylactic Haemostasis Prior to Biopsy of Endobronchial Lesions (BEVACS): A Randomized Controlled Trial.

No difference in postbiopsy bleed was observed between the application of electrocautery or instillation of cold saline plus adrenaline before biopsy of those endobronchial lesions which were likely to bleed more after biopsy. Although controlled prophylactic electrocautery using 15 watts did not impair the quality of EBB specimens, a higher wattage may change this observation, as well as the bleeding quantity.
