Children with mucopolysaccharidoses--three cases report.
The mucopolysaccharidoses (MPS) are a group of inherited disorders of metabolism, with widespread, progressive involvement and derangement of many organs and tissues. Because of their disabling nature, frequent surgical intervention for the abnormality entailed is common, and is associated with a high degree of anesthetic risks perioperatively. One of the major hazards which we find clinically is airway difficulty. Multiple factors are present in the mucopolysaccharidoses to make airway management and trachael intubation potentially hazardous. Aside from generalized infiltration and thickening of the soft tissues, the oropharynx may be obstructed by a large tongue with tonsillar hypertrophy. Also, the friable mucosa covering the nasal and oral pharynx renders these structures easily to bleed and edematous. The neck is typically short and immobile, and the cervical spine and tempromandibular joint may have a limited range of movement. From our experience, we have learned not to overlook the propensity of airway difficulty. The uniqueness of their anatomy and extremely sensitive airway often result in failed intubation and bronchospasm even after successful intubation. Recently, in Mackay Memorial Hospital we have encountered in series three pediatric cases with mucopolysaccharidoses (one Hurler and two Hunter syndromes). In this report we would like to share our experiences and to discuss the anesthetic risks and management of the MPS patients.
