Lidocaine supplementation in clove-oil and 2-phenoxyethanol anesthesia for gilt...
Tchobanov, Carolina F.; Vaz, Mariana; Pires, Damiana; Passos, Ricardo; Antunes, Luís M.; Baptista, TeresaAnimal welfare and reducing stress during procedures are key objectives for success in animal production. Anesthesia has been used for procedures to reduce animal stress and its negative impact on welfare. This study aimed first to refine the concentrations of the anesthetic clove-oil (CO) and lidocaine (L) in gilthead seabream (Sparus aurata) juveniles (56.0 ± 15.09 g) and then combine clove-oil and 2-phenoxye...
Remifentanil bolus dose is a safe procedure to control intense noxious stimuli ...
Ferreira, David A.; Nunes, Catarina S.; Lobo, Francisco; Antunes, Luís M.; Amorim, PedroPatients with hypertension may be more prone to develop hypotension as a consequence of opioid administration under general anesthesia. The hemodynamic and bispectral index responses to a remifentanil bolus in neurosurgical hypertensive patients under target-controlled infusion with propofol and remifentanil are addressed. Ten healthy patients and 10 patients with diagnosed hypertension under pharmacological tr...
Brain tumors may alter the relationship between bispectral index values and pro...
Ferreira, David A.; Nunes, Catarina S.; Lobo, Francisco; Casal, Manuela; Antunes, Luís M.; Amorim, PedroStudy Objective: To compare propofol-predicted effect-site concentrations (PropCe) and bispectral index (BIS) of the electroencephalogram during induction of anesthesia in patients with small brain tumors and to analyze BIS and PropCe at loss of consciousness (LOC). Design: Prospective investigation. Setting: Operating theater of a university hospital. Patients: 26 ASA physical status I and II patients, 13 of w...
Neuro-fuzzy techniques to model pharmacodynamic interactions between anesthetic...
Nunes, Catarina S.; Ferreira, David A.; Mendonça, Teresa F.; Amorim, Pedro; Antunes, Luís M.The aim of this preliminary study was to try to identify the effect of propofol and remifentanil on bispectral index of the electroencephalogram (BIS), and to determine if a model can be generalized between different patients. We used the data from three patients under stable propofol and remifentanil anesthesia for neurosurgical procedures. A Takagi-Sugeno-Kang (TSK) fuzzy model was used to describe the effect...
