Use of terbutaline sulfate in a subcutaneous infusion. Pump to treat preterm labor.

The subcutaneous infusion of terbutaline sulfate (Brethine) by an external, portable pump offers an innovative new approach for treating preterm labor. Care of women receiving this therapy modality requires a basic understanding of the pump and its function. Researchers indicate pump tocolysis has numerous advantages over oral tocolysis: daily medication doses are lower, causing fewer side effects; onset of the medication is faster, resulting in the ability to control contractions before cervical changes occur; there is improved patient compliance; and there are higher pregnancy prolongation rates. Successful use of the pump requires in-depth education of the patient and her family. Home support and follow-up are also critical to the success of outpatient management of patients being treated with pump tocolysis.
