1/7. Complete recovery of consciousness in a patient with decorticate rigidity following cardiac arrest after thoracic epidural injection.

    A 46-yr-old man with dysaesthesia (burning sensation) following herpes zoster in the left upper chest region was treated with a single thoracic (T2/T3) epidural injection (1.0% lidocaine 3 ml 0.125% bupivacaine 3 ml) as an outpatient. Twenty minutes after the injection, a nurse noticed the patient to be unconscious with dilated pupils, apnoea and cardiac arrest. Following immediate cardiopulmonary resuscitation, the patient was treated with an i.v. infusion of thiamylal sodium 2-4 mg kg-1 h-1 and his lungs were mechanically ventilated. When the patient developed a characteristic decorticate posture, mild hypothermia (oesophageal temperature, 33-34 degrees C) was induced. On the 17th day of this treatment, after rewarming (35.5 degrees C) and discontinuation of the barbiturate, the patient responded to command. weaning from the ventilator was successful on the 18th day. About 4 months after the incident, the patient was discharged with no apparent mental or motor disturbances. We suggest that mild hypothermia with barbiturate therapy may have contributed to the successful outcome in this case.

2/7. Decerebrate rigidity with preserved cognition and gait: a possible role of anoxic-ischemic brain damage.

    A case of stable decerebrate posture in the upper limbs following sudden loss of consciousness and prolonged coma is described. The patient recovered most of her cognitive functions and gait, without clinical, neurophysiological or neuroradiological evidence of brainstem lesion. MRI shows borderzone infarcts. It is suggested that anoxic-ischemic cortical damage, affecting specially corticoreticular neurons, could explain the development of decerebrate rigidity in patients without apparent brainstem lesion.

3/7. MR findings of decerebrate rigidity with preservation of consciousness.

    We describe a case of decerebrate rigidity, with preservation of consciousness, caused by a discrete pontine tegmentum lesion identified on MR imaging. Lesions within a certain brain stem region are responsible for decerebrate rigidity in animal studies, but there has been a lack of MR imaging evidence in humans. This report also implies that a discrete lesion was responsible for the decerebrate rigidity, while consciousness was preserved.

4/7. Preservation of consciousness in a decerebrating head injured patient.

    We report a patient whose consciousness was preserved even as she developed decerebration following a head injury. Her brainstem reflexes were normal. A large left frontal haematoma was evacuated. She improved remarkably over the next 2 1/2 years.

5/7. A case of attempted suicide by self-hanging.

    A young man arrived at the accident and emergency department after attempting suicidal self-hanging. He was cyanosed and showed severe respiratory distress. His posture, hyperreflexia and state of consciousness suggested decerebration. A dire prognosis was expected. Four days later he recovered. No residual physical or mental sequelae were found during follow up. The "post-suspension syndrome" in our case was similar to those recorded in several continental reviews. Apart from a case report of a "miraculous deliverance" following an unsuccessful judicial hanging at Oxford in 1650, no other report of this syndrome has been made in the English literature. This syndrome has an excellent prognosis and requires very little active intervention to ensure a favourable outcome.

6/7. Traumatic decerebracy with preserved consciousness and voluntary movement.

    Decerebrate rigidity is a frequent occurrence in cases of craniocerebral trauma. It is almost always accompanied by coma and usually denotes a poor prognosis. Primary focal brain stem lesions due to trauma are uncommon and may be accompanied by other diffuse cerebral lesions. This report reviews the anatomical basis and clinical findings of a unilateral brain stem lesion in a patient with traumatic decerebracy and preserved consciousness. The anatomical pathways and possible physiological mechanism are discussed, and a few comments on the prognosis of such lesions are given.

7/7. eclampsia--monitoring of intraventricular CSF pressure.

    Continuous monitoring of the intraventricular CSF pressure was performed for 48 h in a woman of 23 years who had postpartum eclampsia with unconsciousness for 5 days and decerebrate spasms suggesting compression of the upper brainstem. The intraventricular pressure was normal with minor variations of 10--20 mm Hg.
