Amobarbital ( Amytal ) anaesthesia : euphoric and dysphoric responses Method - Incidence of euphoric and dysphoric reactions during left- and right-sided amobarbital anesthesia of the internal carotid artery (ICA) and selective anesthesia of the middle cerebral (MCA) and the posterior cerebral (PCA) artery was recorded. Conclusion - It is concluded that unilateral amobarbital anesthesia as such, irrespective of side, may trigger both euphoric and dysphoric responses. The relative frequency obtained is influenced importantly both by the emotional responsiveness of the subjects and the emotional climate of the test situation. www.general-anaesthesia.com /amobarbital.html   (283 words)

Amobarbital Summary Amobarbital should not be given to patients with a history of addiction; personal or family history of porphyria; severe kidney, liver, or lung disease; or hypersensitivity to barbiturates.

University of Washington Regional Epilepsy Center at Harborview Medical Center The intra-carotid amobarbital "Wada" test is performed primarily on epilepsy surgical candidates to determine which side of the brain speech, memory, and motor functions reside. A dye is injected into the catheter which allows the radiologist to view either side of the brain in the search for abnormalities, particularly of a vascular nature. X-rays are taken of the right side of the brain and once x-rays have been reviewed, amobarbital is again injected into the catheter. pcs.hmc.washington.edu /Epilepsy/PtSvcs/Wada.htm   (421 words)

Epilepsia, in press   (Site not responding. Last check: 2007-10-11) Results: Despite differences between the methohexital and amobarbital test protocols, the behavioral and neurological effects of the two anesthetics are similar. Behavioral and EEG indices return to baseline more quickly and more completely with methohexital than with amobarbital, allowing several repetitions of the procedure without incremental drowsiness, and the total time taken for the procedure is less with methohexital than with amobarbital. Conclusion: The results of language and memory testing in the Wada test are equivalent for amobarbital and methohexital except that methohexital has a briefer duration of action and is associated with less sedation. www-personal.umich.edu /~gusb/epilepsia.brev.html   (204 words)
