Simkin's Labor Progress Handbook
Wiley-Blackwell (Verlag)
978-1-119-75446-6 (ISBN)
This invaluable guide unravels the complexities of labor, equipping you with practical strategies to overcome challenges encountered along the way. Inside this comprehensive book, you’ll discover a wealth of low-technology, evidence-based interventions designed to prevent and manage difficult or prolonged labors. Grounded in research and practical experience, these approaches are tailored by doulas and clinicians to provide optimal care and achieve successful outcomes.
The fifth edition of this prestigious text includes information on:
- Labor dystocia causes and early interventions and strategies promoting normal labor and birth
- Application of fetal heart rate monitoring (intermittent auscultation, continuous electronic fetal monitoring, and wireless telemetry) while promoting movement and labor progress
- The role of oxytocin and labor progress, and ethical considerations in oxytocin administration
- Prolonged prelabor and latent first through fourth stage labor, addressing factors associated with dystocia
- Positions, comfort measures and respectful care
With meticulous referencing and clear, practical instructions throughout, »Simkin’s Labor Progress Handbook« continues to be a timely and accessible guide for novices and experts alike, including doulas, nurses, midwives, physicians, and students.
