Questions and Answers

What is the primary reason why children require closer monitoring of blood loss during surgery?

  • Because they are more susceptible to respiratory infections.
  • Because their immune systems are not fully developed.
  • Because they need to eat frequently to maintain energy.
  • Because their blood volume is smaller compared to adults. (correct)
  • Why would the surgeon request special blood tests preoperatively?

  • To identify any bleeding problems or clotting disorders. (correct)
  • To check for any underlying medical conditions.
  • To determine the child's blood type.
  • To assess the child's respiratory function.
  • What is the equivalent volume of blood that a seven-pound baby can afford to lose before requiring a blood transfusion?

  • Half a pint.
  • One pint.
  • One quarter of a pint.
  • One ounce. (correct)
  • Why is it important to ensure the child's respiratory tract is unobstructed before administering a general anesthetic?

    Study Notes

    Pediatric Surgery Considerations

    • Children have a smaller circulating blood volume compared to adults, making it critical to monitor blood loss during surgery to avoid shock.
    • A 7-pound baby has a blood volume of approximately 250-350 ml, and can only afford to lose 10% of that (25-30 ml or roughly 1 ounce) before requiring a blood transfusion.
    • The circulator and scrub must closely monitor wound suction container and irrigation fluids used to accurately track blood and fluid loss.
    • Bloody sponges should be weighed to keep an accurate accounting of total blood and fluid loss.

    Preoperative Considerations

    • The surgeon may request special blood tests preoperatively to determine the child's blood clotting time and potential bleeding problems.
    • It is crucial to identify any bleeding disorders, such as hemophilia, before surgery to ensure proper preparation.

    Anesthesia and Respiratory Considerations

    • Children are more susceptible to respiratory infections and pneumonia due to their underdeveloped immune systems.
    • General anesthesia is commonly used in pediatric surgery, and it is essential to ensure the child's respiratory tract is unobstructed.
    • If a child has "sniffles" or sounds congested, it may be risky to administer general anesthesia, and the OR nurse or anesthesia staff should be informed.

    Nutrition and Feeding Schedules

    • Infants and children require frequent feeding to provide them with energy for growth and development.
    • It is essential to minimize interruptions to the feeding schedule to avoid weakening and dehydrating the infant, which increases the risk of surgery.
    • Infants may be fed up to a couple of hours before surgery, and the time of the last feeding is based on the age of the infant or child and the scheduled surgery time.

    Instrument and Suture Selection

    • Pediatric surgery requires special attention to instrument and suture selection, as well as surgical draping material and positioning techniques, due to the smaller size of infants and children.
    • Adult-sized instruments, sutures, drapes, and positioning devices are not suitable for pediatric patients.
