Chapter 15: Nursing Care During Labor & Birth

Nursing Care During Labor & Birth begins by exploring theories regarding the onset of labor, such as progesterone withdrawal and prostaglandin release, and defines the four integrated concepts essential for a successful birth: the passage (maternal pelvis), the passenger (fetus), the powers (uterine contractions), and the psyche (psychological state). Significant attention is given to the passenger, analyzing fetal skull structure, molding, and the critical importance of fetal attitude, lie, and presentation—specifically distinguishing between cephalic, breech, and shoulder presentations. The text explicates the cardinal movements of labor (descent, flexion, internal rotation, extension, external rotation, and expulsion) that the fetus must navigate to pass through the birth canal. The powers of labor are examined through the phases of uterine contractions—increment, acme, and decrement—and the resulting cervical effacement and dilatation. The chapter delineates the four stages of labor: the first stage, subdivided into latent, active, and transition phases where cervical dilation reaches 10 cm; the second stage, characterized by pushing and the birth of the newborn; the third stage, involving the separation and expulsion of the placenta via Schultze or Duncan mechanisms; and the fourth stage, which focuses on immediate postpartum recovery and bonding. Crucial emphasis is placed on fetal assessment using electronic fetal monitoring to interpret baseline heart rates, variability, and periodic changes, identifying benign patterns like accelerations and early decelerations versus ominous signs such as late or variable decelerations that may indicate hypoxia or cord compression. Furthermore, the text outlines essential nursing interventions, including Leopold maneuvers to determine fetal position, pain management strategies, and the recognition of maternal and fetal danger signs like meconium staining or abnormal vital signs to ensure safety and quality care.
