Physicians tend to overestimate when predicting survival in all palliative care patients, including those receiving chemotherapy.

The simplified PPI showed essentially the same predictive value as the original PPI and is an alternative when clinicians have difficulties in diagnosing delirium.

The purpose of this study was to evaluate the effect of prostaglandin E I (PGEj) on CO 2 reactivity during cerebral aneurysm surgery in 37patients under neuroleptoanaesthesia (NLA ) (avant l'hypotension : 2,74 ._+ 0, pendant l'hypotension : 2,54 +__ O, apr~s l'hypotension : 2, que dans le groupe B ( avant I 'hypotension 1, 54 ._+ O, pendant l'hypotension 1, apr~s l'hypotension 1,49 ._+ 0, (P < O, 01

The cerebral vasomotor reactivity to carbon dioxide was studied, using a thermal gradient blood flow meter in 43 patients with intracranial cerebral aneurysm under deliberate hypotension induced by prostaglandin E t (PGE I) infusion. The patients were divided into three groups according to the neurological status. Patients in Groups in Group A, 0.71 +_ 0.25

This study was performed to examine changes in local cerebral blood flow during hypotensive anaesthesia with either prostaglandin E1 (PGE1) or trimethaphan (TMP). Local cerebral blood flow (LCBF), mean blood pressure (MBP), heart rate (HR ), and hourly urine output (UO) were studied in 51 patientsDeliberate hypotension is frequently employed to decrease blood loss during surgery and to diminish the need for and the risk of blood transfusion. L2 The characteristics of an ideal hypotensive drug include easy administration, predictability, a rapid onset of action, rapid elimination, compatibility with anaesthetic agents, lack of toxic side-effects, maintenance of adequate perfusion to the vital organs at low blood pressure, and absence of rebound hypertension and tachyphylaxis.
