Anesthesia Considerations in Scoliosis Surgery Key Insights for Safer Outcomes

Introduction

Scoliosis, an abnormal lateral curvature of the spine exceeding 10 degrees (Cobb’s angle), can present significant anesthetic challenges—especially in advanced or neuromuscular cases. From preoperative pulmonary assessments to intraoperative neurophysiological monitoring, anesthesia management plays a critical role in ensuring patient safety and optimal surgical results.

Preoperative Evaluation and Patient Preparation

Effective anesthesia care in scoliosis surgery starts with a comprehensive preoperative evaluation.

• Pulmonary Function Tests (PFTs): Essential for identifying restrictive lung disease through reduced Forced Vital Capacity (FVC) and Total Lung Capacity (TLC) while maintaining normal FEV1/FVC ratios.
• Cardiovascular Assessment: ECG and echocardiography help detect potential cardiac complications, including congenital heart defects and cardiomyopathy.
• Neurological Examination: Critical for detecting pre-existing deficits and mitigating medicolegal concerns.

The American Society of Anesthesiologists (ASA) emphasizes that thorough pre-surgical evaluations improve intraoperative safety and postoperative recovery, particularly in high-risk patients.

Intraoperative Anesthetic Management

Anesthesia for scoliosis correction often involves:

• Total Intravenous Anesthesia (TIVA): Preferred for compatibility with intraoperative neuromonitoring (IONM). Common agents include propofol and remifentanil.
• Blood Conservation Strategies: Use of tranexamic acid (15 mg/kg IV loading dose; 1–20 mg/kg/h maintenance) to minimize surgical blood loss.
• Positioning Precautions: Prone positioning demands vigilant monitoring for hemodynamic and airway complications.

A detailed analysis of anesthesia agent effects on neuromonitoring is available in the main journal article at https://doi.org/10.29328/journal.ijcar.1001030.

Neuromonitoring Considerations

Intraoperative neurophysiological monitoringvia Somatosensory Evoked Potentials (SSEPs) and Motor Evoked Potentials (MEPs)helps protect spinal cord integrity.

• Avoid excessive inhalational anesthetic concentrations (>0.5 MAC).
• Minimize or time muscle relaxant use to prevent MEP interference.

Postoperative Care

Following surgery, most patients require ICU admission for close monitoring.

• Respiratory Management: Prompt extubation is preferred to reduce ventilator-associated risks.
• Pain Control: A multimodal analgesic approachincluding acetaminophen, NSAIDs, opioids, and gabapentinsupports faster recovery and reduces hypoventilation risks.

Key Takeaways

• Preoperative cardiopulmonary assessment is critical.
• TIVA remains the gold standard for scoliosis anesthesia with neuromonitoring.
• Blood loss prevention strategies significantly improve outcomes.
• Multimodal analgesia ensures effective postoperative pain management.
