Comparative Study
Traumatic acute subdural hematoma: major mortality reduction in comatose patients treated within four hours.
To discover which factors contributed to recovery after surgical intracranial decompression, we reviewed the records of 82 consecutive comatose patients with traumatic acute subdural hematoma (ASDH) who were treated in a single center under a uniform protocol. The delay from injury to operation was the factor of greatest therapeutic importance. ⋯ Other important prognostic variables included results of the initial neurologic examination, sex, multimodality-evoked potentials, and postoperative intracranial pressure (ICP). If all patients with traumatic ASDH were taken directly to hospitals equipped to diagnose and remove the hematoma within four hours of injury, mortality rates could be reduced considerably.

Findings of computerized tomography (CT) in 183 cases of head injury in children were investigated with special reference to CT findings of mild head injury. As was expected, CT findings of mild head injury fell within the normal range, in almost all cases. However, abnormal findings were noticed in 4 out of 34 cases (12%) in acute stage and 7 out of 76 cases (9%) in chronic stage. ⋯ These findings were invariably converted to cerebral atrophy from 10 days to 2 months after the impacts. In the cases with intracranial hematoma revealed by CT, only 32% of them showed clinical signs of Araki's type IV in their acute stage and 63% of them showed no neurological defects, that is Araki's type I & II. A case of extreme diffuse cerebral atrophy which followed acute subdural hematoma caused by tear of bridging veins without cortical contusion was presented.

[Clinico-echoencephalographic correlations in the early diagnosis of traumatic intracranial hematomas and foci of brain crushing].
The authors examined 254 patients with closed trauma of the skull and brain. Besides clinical examination all patients were subject to unidimensional multiaxial echoencephalography with a modified ultrasonic probe and method of examination Three degrees of brain affection were distinguished according to the clinical signs and three degrees of compression according to the results of echoencephalography, the combination of which allows correct tactics of examination and treatment to be used in patients with severe closed trauma of the skull and brain within the first hours of hospitalization.

In 16 patients with severe head injury and 2 patients with subarachnoid hemorrhage, positive end-expiratory pressure (PEEP) ventilation was required to maintain adequate oxygenation. The effects of PEEP on intracranial pressure (ICP) were evaluated with respect to the volume-pressure response (VPR), an indicator of intracranial compliance, and the static lung compliance (CL). ⋯ In addition, however, decreased lung compliance may buffer these effects in patients who have decreased intracranial compliance. We propose that ICP monitoring and intracranial compliance determination are necessary in the management of brain-injured patients requiring PEEP ventilation.
