Indications for Intubation in Patients with Suspected CVA
Primary Indications for Intubation in CVA Patients
- The American College of Anaesthesiologists recommends intubation for patients with a Glasgow Coma Scale (GCS) score ≤ 8, which indicates severe impairment of consciousness and inability to protect the airway 1, 5
- Significantly deteriorating level of consciousness, defined as a fall in GCS of two or more points, or a fall in motor score of one or more points, is an indication for intubation 1, 4
- Loss of protective laryngeal reflexes, which increases risk of aspiration, is an indication for intubation 1, 5
- Respiratory failure, including failure to achieve PaO₂ ≥ 13 kPa, hypercarbia (PaCO₂ > 6 kPa), or spontaneous hyperventilation (PaCO₂ < 4.0 kPa), is an indication for intubation 1
- Active seizures that compromise airway protection are an indication for intubation 1, 5
Intubation Technique for CVA Patients
- The American College of Anaesthesiologists recommends rapid sequence induction with appropriate hemodynamic management for intubation in CVA patients 1, 5
- Monitoring blood pressure closely during intubation, with targets specific to stroke type, such as SBP > 110 mmHg and < 185 mmHg for acute ischemic stroke, is recommended 1, 3
- A recommended drug regimen for induction includes high-dose fentanyl (3-5 μg/kg), alfentanil (10-20 μg/kg), or remifentanil TCI (Cpt ≥ 3 ng/ml) 1, 4
