Psychology of Childbirth
Psychology of Childbirth - Key Notes
Learning Objectives
- Understand various legal cases regarding childbirth, including moral and legal issues tied to fetal rights.
- Learn the operational principles and implications of ultrasound technology and Electronic Fetal Monitoring (EFM).
- Explore the use of EFM in legal contexts, particularly regarding claims of brain injury.
- Discuss cognitive biases, such as counterfactual reasoning and hindsight bias, as they relate to childbirth events.
- Analyze misconceptions regarding the causation of cerebral palsy (CP).
The Georgia Case: Jefferson v Griffin Spalding County Hospital Authority (1981)
Background of the Case:
- Jessie Mae Jefferson was the patient.
- She had a religious belief that she had been healed by divine intervention regarding her childbirth.
- Medical concerns: Complete placenta previa identified via ultrasound, with a 99% fetal death rate and a significant maternal risk (50%).
Court Intervention:
- The hospital sought a court ruling for a cesarean section against the mother's wishes.
- The court ruled against the mother's autonomy, prioritizing the unborn child's right to life over the mother's religious freedoms.
Outcome:
- Jefferson delivered a healthy baby vaginally, despite earlier assessments.
- The second ultrasound revealed that the placenta had moved, negating the initial need for surgery.
Implications: Key takeaway on autonomy and legal rights concerning childbirth.
The Pennsylvania Case: Amber Marlowe
Initial Situation:
- Marlowe went into labor in 2004, and ultrasound indicated fetal size over 13 pounds, suggesting a cesarean delivery.
Legal Trouble:
- Marlowe sought to find another hospital after expressing confidence in her ability to deliver vaginally based on prior experiences.
- The first hospital's lawyers obtained legal guardianship over the unborn child to enforce surgical intervention if necessary.
Resolution:
- At a different hospital, she successfully delivered naturally, experiencing no complications.
Implications: Highlights the conflict between medical authority and maternal autonomy.
Understanding Ultrasound Technology
- Function:
- Utilizes high-frequency sound waves (>20,000 Hz) to form images of fetal development.
- Principles involved: Sound waves reflect differently based on tissue density, which is known as acoustical impedance.
- Limitations: Challenges include acoustic absorption, leading to potential false positives and missed diagnoses.
Electronic Fetal Monitoring (EFM)
Overview:
- Widely used during labor, EFM is present in approximately 85% of hospital births.
- It was introduced with a promise of reducing risks such as cerebral palsy, intellectual disabilities, and perinatal mortality.
Concerns:
- EFM interpretation can be subjective, with experts often disagreeing on readings.
- High rates of false positives (>99%) for fetal distress have been documented.
- Increased C-section rates with EFM usage have not correlated with improved outcomes.
Fetal Heart Monitoring Interpretations
- Types of Changes:
- Acceleration: Abrupt heart rate increase, signifying fetal well-being.
- Variable Deceleration: Abrupt heart rate decrease, which can indicate fetal distress if severe or repetitive.
- Late Deceleration: Gradual decrease post-contraction; often a concerning sign.
Cognitive Biases in Childbirth Contexts
- Counterfactual Reasoning: Examining what could have occurred if a different decision was made during labor.
- Hindsight Bias: Believing that past events were more predictable than they actually were, affecting judgments on pregnancy outcomes.
Misconceptions Around Cerebral Palsy (CP)
- Causation Myths: It is important to dispel the myth regarding the association between CP and obstetric mishaps, emphasizing multifactorial causes of CP rather than attributing them solely to childbirth procedures.
