Anesthesia for an achondroplastic dwarf presenting for urgent cesarean section

Abstract

Achondroplasia is a physeal dysplasia which leads to dwarfism secondary to a decrease in the proliferation of cartilage in the growth plate. This, coupled with normal persistent bone formation, leads to the development of short tubular bones. 1 Achondroplastic dwarfism is among the more common types of dwarfism and is inherited as an autosomal dominant trait. Its incidence is reported as 1 in 26,000 live births. Most achondroplastic dwarfs have a normal life span. 2 The selection and management of anesthesia for the achondroplastic dwarf must take into account a variety of anatomic deformities. The physiologic and hormonal changes of pregnancy further complicate anesthetic administration. We report the safe use of a continuous lumbar epidural anesthetic in an achondroplastic dwarf who presented for urgent cesarean section.
