Intracranial pressure (ICP), mean arterial pressure (MAP), and cerebral perfusion pressure (CPP) in a patient with traumatic brain injury undergoing bronchoscopy under general anesthesia with myorelaxants. ICP increased to 45 mmHg and CPP decreased concomitantly to 40 mmHg. Broncoscopy was stopped, further sedation given and manual hyperventilation administered briefly. ICP and CPP returned to normal levels.
