Insights
Pediatric epilepsy surgery is safe but involves significant blood loss, particularly in longer procedures. Careful monitoring of blood loss and transfusion needs is crucial for young patients undergoing this treatment.
Area of Science:
- Pediatric Neurosurgery
- Epilepsy Surgery
- Anesthesiology
Background:
- Resective epilepsy surgery effectively reduces seizures in drug-resistant epilepsy.
- Assessing intraoperative blood loss, transfusion needs, and hypothermia is vital for pediatric epilepsy surgery.
- Understanding surgical outcomes in young children is critical for optimizing patient care.
Purpose of the Study:
- To evaluate intraoperative blood loss in pediatric epilepsy surgery.
- To determine transfusion requirements for pediatric epilepsy surgery patients.
- To assess the degree of hypothermia during pediatric epilepsy surgery.
Main Methods:
- Retrospective chart review of patients undergoing epilepsy surgery over 25 years.
- Inclusion criteria: patients up to 6 years of age.
- Exclusion criteria: patients with insufficient data.
Main Results:
- Analyzed 45 pediatric patients (mean age 3.2 years).
- Average blood loss was 150 ml (11.7% of estimated blood volume), correlating with surgery duration.
- Minimal body temperature drop observed (35.7°C), with 23 patients receiving erythrocyte concentrate transfusions.
Conclusions:
- Pediatric epilepsy surgery is a safe procedure.
- Significant blood loss can occur, especially in lengthy surgeries.
- Careful management of blood loss and temperature is essential for pediatric patients.
Background:
Resective epilepsy surgery is an established and effective method to reduce seizure burden in drug-resistant epilepsy. It was the objective of this study to assess intraoperative blood loss, transfusion requirements and the degree of hypothermia of pediatric epilepsy surgery in our center.
Methods:
Patients were identified by our epilepsy surgery database, and data were collected via retrospective chart review over the past 25 years. Patients up to the age of 6 years were included, and patients with insufficient data were excluded.
Results:
Forty-five patients with an age of 3.2 ± 1.6 (mean ± SD) years and a body weight of 17 [14; 21.5] kg (median [25%, 75% percentile]) were analysed. Duration of surgery was 3 h 49 min ± 53 min, which was accompanied by an intraoperative blood loss of 150 [90; 300] ml. This corresponded to 11.7 [5.2; 21.4] % of estimated total blood volume, ranging from 0 to 75%. A minimal haemoglobin count of 8.8 ± 1.4 g/dl was measured, which was substituted with erythrocyte concentrate (100 [0; 250] ml) in 23 patients. Body core temperature dropped from 36.0 ± 0.7°C at baseline to a minimum of 35.7 ± 0.7°C, and increased significantly (p < 0.001) thereafter to 37.1 ± 0.7°C until the end of surgery. A significant (p = 0.0003) correlation between duration of surgery and blood loss (Pearson r = 0.52) was observed. However, age, minimal body temperature or number of antiepileptic drugs seemed to have no impact on blood loss.
Conclusion:
Resective epilepsy surgery is a safe procedure even in the pediatric population, however it is associated with significant blood loss especially during long surgical procedures.
