title: Acute and chronic tocolysis.
abstract: Preterm birth occurs in 12% of all births in the United States. Preterm labor precedes approximately half of these births. Tocolysis is used in the short term to prolong pregnancy long enough to administer corticosteroids and/or facilitate transfer to a tertiary care center. A number of agents have been used for this therapy, which will be discussed in the following chapter.
