Insights
Children undergoing craniosynostosis surgery face risks of significant postoperative events. Key risk factors include low body weight, higher anesthesia risk, and intraoperative transfusions, guiding ICU admission decisions.
Area of Science:
- Pediatric Surgery
- Anesthesiology
- Critical Care Medicine
Background:
- Craniosynostosis repair surgery carries a significant risk of postoperative complications requiring intensive care unit (ICU) admission.
- Identifying predictors of these events is crucial for optimizing patient management and resource allocation.
Purpose of the Study:
- To investigate variables influencing the risk of postoperative cardiorespiratory and hematological events after craniosynostosis repair.
- To develop recommendations for postoperative intensive care unit (ICU) admission based on identified risk factors.
Main Methods:
- Retrospective review of 225 children undergoing open craniosynostosis repair over a 10-year period.
- Primary outcome: incidence of predefined cardiorespiratory and hematological events requiring ICU admission.
Main Results:
- Incidence of cardiorespiratory events was 14.7%; hematological events were 29.7%.
- Predictors for cardiorespiratory events included: body weight <10 kg, ASA physical status 3 or 4, intraoperative transfusion >60 ml/kg packed erythrocytes, and intraoperative complications.
- Predictors for hematological events included: body weight <10 kg, ASA physical status 3 or 4, intraoperative transfusion >60 ml/kg packed erythrocytes, hemostatic product transfusion, and absence of tranexamic acid.
Conclusions:
- Pediatric patients <10 kg, ASA physical status 3-4, requiring significant intraoperative transfusion, or experiencing complications are at higher risk for postoperative events.
- Tranexamic acid administration correlated with reduced postoperative events.
- A validated predictive algorithm aids in risk stratification for pediatric craniosynostosis surgery patients.
Background:
Craniosynostosis surgery is associated with clinically significant postoperative events requiring intensive care unit (ICU) admission. The authors investigate specific variables, which might influence the risk for these events, and thereby make recommendations regarding the need for postoperative ICU admission.
Methods:
A retrospective review of 225 children undergoing open craniosynostosis repair at a single center during a 10-yr period is reported. The primary outcome measure was the incidence of predefined clinically relevant postoperative cardiorespiratory and hematological events requiring ICU admission.
Results:
The incidences of postoperative cardiorespiratory and hematological events requiring ICU care were 14.7% (95% CI, 10.5 to 20.1%) and 29.7% (95% CI, 24.0 to 36.3%), respectively. Independent predictors of cardiorespiratory events were body weight less than 10 kg, American Society of Anesthesiologists physical status 3 or 4, intraoperative transfusion of greater than 60 ml/kg packed erythrocytes, and the occurrence of an intraoperative complication. The independent predictors of hematological events were body weight less than 10 kg, American Society of Anesthesiologists physical status 3 or 4, intraoperative transfusion of greater than 60 ml/kg packed erythrocytes, transfusion of hemostatic products (fresh-frozen plasma, platelets, and/or cryoprecipitate), and tranexamic acid not administered.
Conclusions:
Children undergoing craniosynostosis surgery are at increased risk for clinically significant postoperative events requiring ICU admission if they are less than 10 kg body weight, American Society of Anesthesiologists physical status 3 or 4, require intraoperative transfusion of greater than 60 ml/kg of packed erythrocytes, receive hemostatic blood products, or if they develop a significant intraoperative complication. Tranexamic acid administration was associated with fewer postoperative events. A predictive clinical algorithm for pediatric patients having major craniosynostosis surgery was developed and validated to risk stratify these patients.
