“…In addition some authors proposed the use of CFAM amplitude patterns as a prognostic tool after hypoxic-ischaemic encephalopathy periods Hellström-Westas et al, 1995a,Thornberg andEkström-Jodal, 1994). Furthermore, the effects of hypoxia, ischaemia and anaesthetics on CFAM amplitude analysis have been studied using different animal models Aberg et al, 1989;Prior et al, 1978;Toner et al, 1995, Yuan et al, 1995. In our experiments, no burst-suppression activity was seen which means that halothane anaesthesia was appropriate.…”
