Sports-related traumatic brain injury, Bicycle trauma.
SAMU on arrival Glasgow Coma Scale 5, normotensive, normal RR, bradycardia. Fentanyl 75mcg iv (13:10) h + Midazolam 5mg iv + ac. tranexamic iv. Later Etomidate 20mg iv + Fentanyl 75mcg iv + Rocuronium 50mcg iv.
Later Midazolam 10mg iv + rocuronium 50mcg iv + 600cc SSF. They perform immobilization with a Philadelphia collar + pelvic girdle + empty mattress. Apparent right clavicle fracture + right shoulder contusion. Ecofast +. They do IOT.
Anisocoria with arreactive pupils
An ecofast was performed, which seemed positive, and a direct transfer to Computerized tomography was decided.
Brain edema with sulcal effacement. It is conditioning a mass effect with compression of the ipsilateral lateral ventricle and subfalcine herniation, with a midline shift of 5 mm.
Effacement of the suprasellar and perimesencephalic cisterns in relation to signs of descending transtentorial herniation. Hyperdense lesions in the left hemispheric convexity suggestive of cerebral contusion, with an associated subarachnoid hemorrhage component, extending through the tentorium and basal cisterns.
Small pneumocephalus in the basal frontal, anterior temporal and left occipital pole. Trace of a left parietotemporal fracture, which extends through the Petrous bone conditioning its longitudinal fracture, until it reaches the greater wing of the sphenoid and the lateral wall of the left sphenoid sinus. Partial occupation of mastoid cells and middle ear. There are no clear signs that suggest disruption of the ossicular chain. Partial occupation of both sphenoid sinuses with an air bubble inside the left one. Probable diastasis of the left lambdoid suture. Increased left convex extracranial soft tissue and to a lesser extent in the right parieto-occipital region, in relation to hematomas.
Multifragmentary fracture of the middle third of the right clavicle. 4th and 5th right rib arch fracture. Right peripheral pulmonary contusions, with cystic image suggestive of pneumatocele.
A left decompressive craniectomy is performed.
Control CT 24 hours after surgery: postoperative changes with a decrease in the mass effect on midline structures, although with signs of radiological worsening. There is an increase in the hemorrhagic component of parenchymal contusions and the appearance of hemoventricular cells, as well as mild Tetraventricular hydrocephalus.
Tendency to polyuria last night for which a half ampoule of minirin was administered,
