Five cases of unilateral vocal cord paralysis/paresis were diagnosed following extracorporeal membrane oxygenation for newborn respiratory failure.All were right sided and transient in nature.None of the five patients had other findings commonly associated with vocal cord palsy.The extracorporeal membrane oxygenation procedure requires surgical dissection in the carotid sheath on the right side of the neck,an area immediately adjacent to both the vagus and recurrent laryngeal nerve.It is speculated that vocal cord paralysis in these infants was acquired as a result of the extracorporeal membrane oxygenation cannulation.Although the vocal cord paralysis resolved in all cases,two patients had difficult courses after extracorporeal membrane oxygenation.Therefore,laryngoscopic examination should be considered for patients after extracorporeal membrane oxygenation. |
