ICP threshold in CPP management of severe head injury patients.

Background: Elevated intracranial pressure (ICP) is significantly associated with high mortality rate in severe head injury (SHI) patients. However, there is no absolute agreement regarding the level at which ICP must be treated. The objective of this study was to compare the outcomes of severe head injury patients treated by setting the ICP threshold at >or=20 mm Hg or >or=25 mm Hg.

Anatomical position of the asterion and its underlying structure.

Surface anatomy is important for surgical planning. The asterion has been believed and used for locating the underlying posterior fossa dura. To prove whether this landmark is reliable or not, forty-three fixed heads of cadaver were dissected.

The changing pattern of head injury in Thailand.

Objective: To determine whether patterns of head injury are changing with time.

Materials And Methods: A total of 3194 and 4217 consecutive trauma patients who attended the emergency room in 1985-86 and 1996 respectively were studied with respect to age, sex, cause of injury, injury severity, pathology, and outcome.

Results: The number of patients with head injury in 1996 nearly doubled (1224/4,217:29.

Intraoperative intracranial aneurysm rupture.

119 patients with surgically treated intracranial aneurysm between December 18, 1984 and October 1997 were analyzed resulting in nine patients with intraoperative aneurysm rupture. These nine cases formed the basis of this study. The incidence of intraoperative aneurysm rupture was 7.

Nonshaved cranial neurosurgery.

Background: Preoperative shaving for cranial neurosurgical procedures is still recommended in textbooks. There are reports demonstrating the success of nonshaved surgery. The objective of this study was to compare the surgical infection rate of cranial neurosurgical procedures with two different scalp preparations: shaved or nonshaved.
