FDA Warning/Regulatory Alert
Note from the National Guideline Clearinghouse: This guideline references a drug(s) for which important revised regulatory and/or warning information has been released.
- February 17, 2011 – Brethaire, Brethine, Bricanyl (terbutaline sulfate) : The U.S. Food and Drug Administration (FDA) notified healthcare professionals that injectable terbutaline should not be used in pregnant women for prevention or prolonged treatment (beyond 48-72 hours) of preterm labor in either the hospital or outpatient setting because of the potential for serious maternal heart problems and death. In addition, oral terbutaline should not be used for prevention or any treatment of preterm labor because it has not been shown to be effective and has similar safety concerns. FDA is requiring the addition of a new Boxed Warning and Contraindication to the terbutaline drug labels to warn healthcare professionals about these risks.

Guideline Objective(s)
- To aid practitioners in making decisions about appropriate obstetric and gynecologic care
- To review nomenclature for fetal heart rate (FHR) assessment, review the data on the efficacy of electronic fetal monitoring (EFM), delineate the strengths and shortcomings of EFM, and describe a system for EFM classification
Target Population
Fetuses at risk for oxygen deprivation because of antepartum complications, suboptimal uterine perfusion, placental dysfunction, and other intrapartum events that can result in adverse neonatal outcome
Interventions and Practices Considered
- Electronic fetal heart monitoring and frequency of tracing reviews
- Intermittent auscultation of fetal heart sounds
- Assessment of maternal medications
- Evaluation and treatment of persistently nonreassuring fetal heart rate tracings
- Intrapartum fetal stimulation (fetal scalp sampling, Allis clamp scalp stimulation, vibroacoustic stimulation, and digital scalp stimulation)
- Fetal pulse oximetry (not recommended)
- Intrauterine resuscitation (e.g., maternal oxygenation, tocolytic therapy, beta-2-adrenergic agents, amnioinfusion, volume expansion or intravenous ephedrine for maternal hypotension secondary to anesthesia)
Major Outcomes Considered
- Rate of intrapartum complications, including neonatal seizures, cerebral palsy, and intrapartum fetal death
- Rate of unnecessary obstetric intervention, including operative vaginal or cesarean delivery
- Rate of perinatal mortality
- False-positive rate of electronic fetal monitoring
- Intraobserver/interobserver variability

Methods Used to Collect/Select the Evidence
Hand-searches of Published Literature (Primary Sources)
Hand-searches of Published Literature (Secondary Sources)
Searches of Electronic Databases
Description of Methods Used to Collect/Select the Evidence
The MEDLINE database, the Cochrane Library, and the American College of Obstetricians and Gynecologists' (ACOG) own internal resources and documents were used to conduct a literature search to locate relevant articles published between January 1985 and January 2009. The search was restricted to articles published in the English language. Priority was given to articles reporting results of original research, although review articles and commentaries also were consulted. Abstracts of research presented at symposia and scientific conferences were not considered adequate for inclusion in this document. Guidelines published by organizations or institutions such as the National Institutes of Health and the American College of Obstetricians and Gynecologists were reviewed, and additional studies were located by reviewing bibliographies of identified articles.

Methods Used to Assess the Quality and Strength of the Evidence
Weighting According to a Rating Scheme (Scheme Given)
Rating Scheme for the Strength of the Evidence
Studies were reviewed and evaluated for quality according to the method outlined by the U.S. Preventive Services Task Force:
I: Evidence obtained from at least one properly designed randomized controlled trial.
II-1: Evidence obtained from well-designed controlled trials without randomization.
II-2: Evidence obtained from well-designed cohort or case–control analytic studies, preferably from more than one center or research group.
II-3: Evidence obtained from multiple time series with or without the intervention. Dramatic results in uncontrolled experiments also could be regarded as this type of evidence.
III: Opinions of respected authorities, based on clinical experience, descriptive studies, or reports of expert committees.
Methods Used to Analyze the Evidence

Methods Used to Formulate the Recommendations
Expert Consensus
Description of Methods Used to Formulate the Recommendations
Analysis of available evidence was given priority in formulating recommendations. When reliable research was not available, expert opinions from obstetrician–gynecologists were used. See also the "Rating Scheme for the Strength of Recommendations" field regarding Grade C recommendations.
Rating Scheme for the Strength of the Recommendations
Based on the highest level of evidence found in the data, recommendations are provided and graded according to the following categories:
Level A - Recommendations are based on good and consistent scientific evidence.
Level B - Recommendations are based on limited or inconsistent scientific evidence.
Level C - Recommendations are based primarily on consensus and expert opinion.
Cost Analysis
A formal cost analysis was not performed and published cost analyses were not reviewed.
Method of Guideline Validation
Internal Peer Review
Description of Method of Guideline Validation
Practice Bulletins are validated by two internal clinical review panels composed of practicing obstetrician-gynecologists generalists and sub-specialists. The final guidelines are also reviewed and approved by the American College of Obstetricians and Gynecologists (ACOG) Executive Board.

Major Recommendations
The grades of evidence (I-III) and levels of recommendations (A-C) are defined at the end of the "Major Recommendations" field.
The following recommendations and conclusions are based on good and consistent scientific evidence (Level A):
- The false-positive rate of electronic fetal monitoring (EFM) for predicting cerebral palsy is high, at greater than 99%.
- The use of EFM is associated with an increased rate of both vacuum and forceps operative vaginal delivery, and cesarean delivery for abnormal fetal heart rate (FHR) patterns or acidosis or both.
- When the FHR tracing includes recurrent variable decelerations, amnioinfusion to relieve umbilical cord compression should be considered.
- Pulse oximetry has not been demonstrated to be a clinically useful test in evaluating fetal status.
The following conclusions are based on limited or inconsistent scientific evidence (Level B):
- There is high interobserver and intraobserver variability in interpretation of FHR tracing.
- Reinterpretation of the FHR tracing, especially if the neonatal outcome is known, may not be reliable.
- The use of EFM does not result in a reduction of cerebral palsy.
The following recommendations are based on expert opinion (Level C):
- A three-tiered system for the categorization of FHR patterns is recommended.
- The labor of women with high-risk conditions should be monitored with continuous FHR monitoring.
- The terms hyperstimulation and hypercontractility should be abandoned.
Definitions:
Grades of Evidence
