Anesthesiology chart. Before the occurrence of trigemino-cardiac reflex (TCR), mean arterial blood pressure (MABP) was 91.0 mmHg and heart rate (HR) was 82.5 beats/minute. At the time of the TCR record, the patient's blood pressure dropped to 37/0 mmHg (MABP, 12.3 mmHg; 86.49% drop from baseline), and concomitantly HR dropped to 61 beats/minute (26.07% drop from baseline). No significant blood loss at the time of the incident was recorded. The applied medications were ephedrin (20 mg), atropin (0.5 mg) and methylprednisolone (60 mg).
