KR Alzaben, SA Abu-Halaweh… - American Journal of …, 2009 - eacademic.ju.edu.jo
One hundred and fifty athymic nude (rnu/rnu) rats were intubated by direct visualizion of the
larynx using a nasal speculum with an attached otoscope as a light source. A blunt, plastic
covered stylet was introduced between the vocal cords as guide for a 16-gauge intravenous
catheter which was used as an endotracheal tube. Successful intubation was performed in
148 out of 150 animals (98.7%). Complications were encountered in 2 animals only (1.3%).
Complications reported were airway injury and bleeding (one animal) and post-extubation …
