Summary
Preoperative low hemoglobin levels in children undergoing cleft surgery did not increase perioperative risks. However, anesthesia safety remains a concern for anemic children with difficult airways due to reduced oxygen reserves.
Area of Science:
- Pediatric Anesthesiology
- Surgical Patient Safety
- Hematology in Pediatrics
Background:
- Low preoperative hemoglobin (Hb) levels pose challenges for anesthetists regarding surgical proceed decisions.
- Anemia in pediatric patients can impact anesthetic management and perioperative outcomes.
Purpose of the Study:
- To prospectively evaluate perioperative morbidity in healthy infants and children with preoperative Hb levels ≥ 7 g/dl undergoing cleft lip and palate surgery.
- To compare morbidity between children with Hb 7-10 g/dl and those with Hb > 10 g/dl.
Main Methods:
- Prospective study of 200 healthy children (3 months–5 years) undergoing cleft surgery under general anesthesia.
- Categorization into two groups based on preoperative Hb levels: Group A (7-10 g/dl) and Group B (>10 g/dl).
- Monitoring of perioperative morbidity, including hypoxemia and cardiovascular stability.
Main Results:
- No significant differences in perioperative morbidity were observed between Group A and Group B.
- Hypoxemia episodes (SpO2 < 91%) occurred in 8 patients in Group A and 6 in Group B during airway management.
- All patients maintained stable cardiovascular parameters, with transient bradycardia during desaturations.
Conclusions:
- General anesthesia for pediatric cleft surgery appears safe in children with preoperative Hb levels as low as 7 g/dl.
- The safety of general anesthesia in anemic infants and children with potentially difficult airways warrants caution due to diminished oxygen reserves.
