Asphyxia
Attendance and Overview
Attendance numbers discussed: 1,000 attendees; previous maximum was 800.
Attendance as part of the scoring system emphasized.
Recap of Previous Week
Asphesia Neonatorium discussed:
Also known as: Birth Asphesia, Neonatal Asphesia.
Definition: Lack of oxygen to initiate and sustain breathing in newborns.
Resulting Condition: If lack of oxygen persists, the baby presents with asphyxia.
Discussed Causes of Asphesia:
Fetal Causes:
Cord around the neck.
Airway obstruction by mucus.
Cord prolapse.
Congenital heart or lung defects.
Prematurity.
Maternal Causes:
Maternal hypertension.
Maternal anemia.
Respiratory disease.
Placenta previa.
Prolonged or obstructed labor.
Premature separation of the placenta (abruptio placentae).
Apgar Score Overview: Measurement to assess the health of newborns at 1 and 5 minutes post-delivery.
Types of Asphesia
Mild Asphesia (Asphyxia Pallida):
Characteristics:
Bluish-red or deep cyanotic appearance.
Strong pulse (60-80 bpm).
Responsive to stimuli (squeezes face).
Attempts to breathe or cries (weakly).
Generally scores 4-6 on Apgar.
Severe Asphesia (Asphyxia Calida):
Characteristics:
Pale or green appearance.
Flaccid pulse (less than 40 bpm).
Unresponsive to stimuli.
No attempts to breathe (gasping).
Scores 0-3 on Apgar, indicating severe deprivation of oxygen, circulatory failure, and potential shock.
Treatment Plans for Asphesia
Mild Asphyxia Treatment:
Ensure adequate oxygenation and ventilation.
Minimal interventions and supportive care based on symptoms.
Severe Asphyxia Treatment:
Immediate actions required:
Clear the airway effectively.
Provide oxygen or use bag-assisted ventilation.
Maintain body warmth and alert a doctor.
If response is poor, combine cardiac massage with artificial respiration.
Administer medication only when absolutely necessary.
Monitoring and Observations During Asphesia Management
Assessment of fetal heart rate and general condition during labor and delivery.
Indicators of distress include:
Low fetal heart rates (as low as 60-70 bpm).
Meconium-stained amniotic fluid suggests potential asphyxia.
Maternal signs such as excessive fetal movements.
Reception Preparation for Asphyxiated Newborns
Preparation for receiving a baby at risk of asphyxia includes:
Assembling a resuscitation tray with necessary equipment:
Ambu bag.
Oxygen source.
Neonatal masks of various sizes.
Radiant warmer.
Ensure all team members are familiar with equipment and protocols.
Keep communication with referral units for potential transfers.
Aftercare and Observation Following Resuscitation
Key observations:
Monitor vital signs (temperature, color, respiratory effort).
Ensure the newborn maintains normal temperature (36.5 °C to 37.5 °C).
Assess for signs of distress or shock, such as:
Chest indrawing.
Nasal flaring.
Cyanosis (blue color).
Monitor blood glucose levels; initiate feeding as soon as possible.
Document all observations, interventions, and responses carefully.
Essential Equipment for Resuscitation
Required tools include but are not limited to:
Radiant heater for temperature regulation.
Clock for timing interventions.
Neonatal intubation equipment (endotracheal tubes).
Suction devices for airway clearance.
Stethoscopes for auscultation.
Drugs for managing complications (e.g., naloxone, epinephrine).
Key Concepts for Successful Management
Immediate action is crucial in cases of asphyxia; delays can lead to severe outcomes.
Continuous monitoring and adaptation of techniques based on responsiveness.
Effective communication among team members enhances patient care quality.
Understanding the implications of interventions and being prepared for complications is essential in neonatal care.
Final Considerations
Aftercare may involve:
Sending the newborn to a higher care facility if symptoms persist.
Continuous observation for at least two hours post-resuscitation, with minute checks during that time.
Participation in follow-up care and monitoring as needed.
