Myocardial Dysfunction in Acute Traumatic Brain Injury Relieved by Surgical Decompression

Table 1

Changes in qualitative ejection fraction (EF) and regional wall motion abnormalities (RWMA) pre and post decompressive craniotomy in a patient with isolated traumatic brain injury.

	Pre decompression	Post decompression
Qualitative EF	35%	55%
RWMA	Basal hypokinesis	None
Blood pressure	88/54 mmHg*	110/62 mmHg
Heart rate	84 bpm	92 bpm
Total crystalloid	1200 mL**	1600 mL
Hematocrit	35%	31%
Anesthesia	Sevoflurane	Sevoflurane
End-tidal sevoflurane	0.5%	1.5%

∗: Ephedrine, 20 mg ephedrine administered to restore blood pressure to 124/72 mmHg.
**: Intravenous fluids administered over 1.5 hours, totaling 1600 mL post decompression (400 mL administered after surgical decompression).
