Study Notes

Week 4: Thermoregulation

Learning Objectives: Students will learn mechanisms of heat production and loss in neonates, identify thermoregulatory issues, discuss monitoring methods, and develop preventative strategies.

Lesson Structure: Introduction (10 minutes)

Icebreaker Activity: Students share their understanding of neonatal thermoregulation.
Importance of Thermoregulation: Neonates have unique physiology, heightened vulnerability to temperature changes, and thermoregulation impacts morbidity and mortality.

Lesson Structure: Heat Production in Neonates (15 minutes)

Key Concepts:
- Non-shivering thermogenesis: Brown adipose tissue (BAT) plays a role, activated by norepinephrine.
- Limited shivering response: Neonates primarily rely on non-shivering mechanisms.
- Increased metabolic rate: Metabolism increases in response to cold stress.
Teaching Methods:
- Interactive Lecture: Diagrams illustrate BAT location and physiology.
- Case Scenario: A preterm infant in cold stress is presented; students consider how heat production mechanisms might fail.

Lesson Structure: Heat Loss Mechanisms in Neonates (20 minutes)

Key Mechanisms:
- Convection: Heat loss to surrounding air.
- Conduction: Heat loss to surfaces in direct contact.
- Radiation: Heat loss to cooler objects.
- Evaporation: Heat loss from skin due to moisture (e.g., post-birth bathing).
Teaching Methods:
- Visual Demonstration: Compare how heat loss occurs in different situations (e.g., radiant warmer vs. uncovered baby).
- Group Activity: Students brainstorm strategies to minimize heat loss.

Lesson Structure: Major Thermoregulatory Issues (15 minutes)

Key Conditions:
- Hypothermia: Causes include lethargy, hypoglycemia, and metabolic acidosis.
- Hyperthermia: Overheating in incubators can cause problems.
- Cold Stress: Events leading to hypoxemia and hypoglycemia.
Teaching Methods:
- Clinical Case Discussions: Analyze examples of hypothermia and hyperthermia in neonates.
- Role Play: Demonstrate how a nurse should respond to a hypothermic neonate.

Lesson Structure: Monitoring Thermoregulation (10 minutes)

Key Tools:
- Axillary temperature: Standard for neonates.
- Skin probes: For continuous monitoring in critical care.

Lesson Structure: Prevention of Thermoregulatory Issues (15 minutes)

Key Strategies:
- Delivery Room Practices: Immediate drying, skin-to-skin contact, use of radiant warmers.
- Environmental Controls: Optimal room temperature, pre-warming linens, and appropriate incubator humidity.
- Family-Centered Care: Educating parents on appropriate dressing and swaddling practices.
Teaching Methods:
- Small Group Work: Development of a thermoregulation protocol for a neonatal unit.
- Simulation: Practice delivery room thermal care for a preterm infant.

Lesson Structure: Summary and Q&A (5 minutes)

Summary: Key points are recapped using a visual aid.
Q&A: Students ask questions and clarify information.

Assessment

Formative: Interactive questions during the session and case-based discussions.
Summative: Post-session quiz on thermoregulation mechanisms and prevention strategies.

Resources

Handouts: Summaries of heat production, heat loss, and management strategies.
