Summary
Highlights
The video begins by focusing on problems with uterine power, specifically ineffective uterine contractions. This category is further divided into hypotonic, hypertonic, and uncoordinated contractions. The first condition discussed is hypotonic contractions.
Hypotonic contractions are defined as low or infrequent uterine contractions, typically less than two to three contractions in 10 minutes. The resting tone of the uterus remains below 10 mmHg, and contraction strength does not rise above 25 mmHg. This condition commonly occurs during the active phase of labor.
The video introduces the topic of nursing care for high-risk postpartum clients, emphasizing the need to understand normal pregnancy processes. The discussion will cover problems related to the 'power' (force of labor), 'passageway' (vaginal wall), 'passenger' (fetus and placenta), and 'psyche' (psychological factors).
Several risk factors contribute to hypotonic contractions: overdistension of the uterus (common in multiple pregnancies or polyhydramnios), hormonal imbalance (insufficient oxytocin levels), maternal fatigue, pelvic or fetal malposition (e.g., non-gynecoid pelvis, breech, or hyperextended fetal head), and a history of previous C-sections (increasing risk of uterine atony).
Signs and symptoms include weak and infrequent contractions that are irregular and insufficiently strong to cause effective cervical dilation, prolonged labor, slow progression of labor (minimal cervical dilation over several hours), and an increased risk of infection due to prolonged rupture of membranes.
Diagnostic tests include monitoring contraction patterns using cardiotocography (CTG) or a tocodynamometer (internal uterine pressure catheter). Cervical examination (internal examination) is also used to assess the progress of cervical dilation and effacement and to determine if contractions are effective.
Management strategies include administering uterotonic medications like oxytocin to stimulate contractions, artificial rupture of membranes (amniotomy) if the bag of water is intact, maternal position changes (e.g., pelvic rock, walking, birthing ball, squatting, or even water birth in some cultures), rehydration and rest, and in severe cases, cesarean section.
Possible complications include fetal distress (assessed by monitoring fetal heart rate for tachycardia or bradycardia), increased need for interventions such as forceps or vacuum delivery, and postpartum hemorrhage due to the inability of the uterus to contract effectively after delivery, leading to dilated blood vessels and excessive bleeding.
Preventive measures include consistent prenatal care (minimum of eight visits to reduce complications), continuous labor support (e.g., from a doula or healthcare provider), and adopting optimal positions during labor. Labor support helps manage stress and fatigue, allowing the mother to conserve energy for pushing.
