Our objective was to determine whether an adult ferret can be intubated as many as 10 times per training session without resulting in trauma to the upper airway. In this program, 8 male ferrets rotated through intubation laboratories, limiting the use of each animal to once every 3 mo. Animals were examined by the veterinary staff after intubations to assess for trauma to upper airway tissue. Each examination was given a trauma grade of 0 for no visible signs of trauma, 1 if erythema of the larynx was present, 2 if visible excoriation of the mucus membranes was present, and 3 if bleeding (frank hemorrhage) was observed. The number of intubation attempts was restricted to 10 per animal per training session. A total of 170 intubations were completed on the ferrets during a 12-mo period. The average number of intubations per laboratory was 8.1 intubations per ferret. In addition, 1.8% of the intubations resulted in erythema (score, 1) after training, and 0.6% of the intubations resulted in excoriation (score, 2). Frank hemorrhage (score, 3) was not noted. The overall percentage of intubations resulting in any trauma during a training session was 0.02%. None of the animals have experienced any major complications to date. This ongoing training program has been used to teach neonatal intubation skills to emergency medicine residents for the past 12 mo. Ensuring the health and safety of the ferrets was paramount. Our results suggest that as many as 10 intubation attempts per session can be performed safely on each ferret without causing excessive trauma.
我们的目标是确定成年雪貂每次训练能否进行多达10次插管而不会对上呼吸道造成创伤。在这个项目中，8只雄性雪貂轮流进入插管实验室，每只动物每3个月最多使用一次。插管后由兽医工作人员对动物进行检查，以评估上呼吸道组织是否有创伤。每次检查根据创伤程度给予分级：0级表示无明显创伤迹象；1级表示喉部有红斑；2级表示可见黏膜擦伤；3级表示观察到出血（明显出血）。每只动物每次训练的插管尝试次数限制为10次。在12个月的时间里，对雪貂总共完成了170次插管。每个实验室雪貂的平均插管次数为8.1次。此外，训练后1.8%的插管导致红斑（评分1级），0.6%的插管导致擦伤（评分2级）。未观察到明显出血（评分3级）。训练期间导致任何创伤的插管总体百分比为0.02%。到目前为止，没有一只动物出现任何重大并发症。在过去12个月里，这个正在进行的训练项目一直用于向急诊医学住院医师传授新生儿插管技能。确保雪貂的健康和安全至关重要。我们的结果表明，每只雪貂每次训练安全进行多达10次插管尝试不会造成过度创伤。
