The aim of this study was to evaluate the bispectral index (BIS) effects in calves through continuous infusion of propofol with or without fentanyl. Eight Holstein male calves (ages from six to twelve months old) with an average weight of 123±18kg were used. All animals participated in both groups, always keeping a minimum interval of one week between the anesthetic procedures; the calves were randomly distributed between groups. Anesthesia was induced with an intravenous (IV) dose of propofol of 5mg kg-1 in control group (GP) or with propofol (4mg kg-1) associated with IV fentanyl 0.001mg kg-1(GF). All the calves were positioned in right lateral recumbency and were allowed to spontaneously breathe room air. Subsequently, the anesthesia was maintained by continuous infusion of propofol at the rate of 0.6mg kg-1 min-1 IV in GP, and associated with the infusion of fentanyl 0.001mg kg-1 hour-1 in GF. Measurements of BIS, signal quality index (SQI) and electromyography (EMG) were evaluated before anesthesia induction (TB), and at 15, 30, 45 and 60 minutes after the beginning of continuous drugs infusion (T15, T30, T45 and T60, respectively). The heart rate (HR), respiratory rate (f), end-tidal carbon dioxide tension (ETCO2) and recovery times were evaluated as well. No significant differences were observed between the groups in the BIS variables and the recovery time was longer in GF. Co-administration of propofol and fentanyl infusions, at the doses reported here, did not change the values of BIS in cattle, but delayed the recovery time. RESUMO: O estudo teve por objetivo avaliar o índice biespectral (BIS) durante a infusão contínua de propofol associado ou não ao fentanil em bezerros. Foram utilizados oito animais machos entre seis e doze meses de idade, holandeses, com massa corporal média de 123±18kg. Todos os animais participaram de ambos os grupos, respeitando-se sempre um intervalo mínimo de uma semana entre uma anestesia e outra, sendo aleatoriamente distribuídos entre os grupos. A anestesia nos bezerros foi induzida com propofol na dose de 5mg kg-1; intravenoso (IV), grupo controle (GP) ou propofol 4mg kg-1 associado ao fentanil 0,001mg kg-1; IV, grupo fentanil (GF) e posicionados em decúbito lateral direito, onde permaneceram respirando espontaneamente ar ambiente. Ato contínuo, a manutenção anestésica foi realizada pela infusão contínua de propofol na taxa de 0,6mg kg-1 min-1; IV GP, associado ou não à infusão de fentanil 0.001mg kg-1 hora-1 GF. A mensuração das variáveis do BIS, índice de qualidade de sinal (IQS) eletromiografia (EMG), frequência cardíaca (FC), frequência respiratória (f) e dióxido de carbono ao final da expiração (ETCO2) foram avaliadas antes da indução anestésica no momento basal (MB), e 15, 30, 45 e 60 minutos após o início da infusão contínua dos fármacos (M15, M30, M45 e M60, respectivamente); o tempo de recuperação também foi avaliado. Não foram observadas diferenças significativas entre os grupos nas variáveis do BIS e o tempo de recuperação foi maior no GF. A co-administração das infusões de propofol e fentanil, nas doses utilizadas nesse estudo, não alterou os valores do BIS em bezerros, porém, prolongou o tempo de recuperação.

In both groups, drugs were administered through an infusion pump over 60 minutes. The measurements of hemodynamic parameters (HR, SAP, DAP, MAP, CO, CVP, mPAP, mPAPO, CI, SI, SVRI and PVRI), respiratory (ETCO2, f, SpO2,VME and VTE), blood gas(PaO2, PaCO2, SaO2, DB, pHandHCO3-) and bispectral index (BIS, SQI and EMG) were evaluated before anesthesia induction(MB), 15, 30, 45 and 60 minutes after the beginning of continuous infusion of drugs (M15, M30, M45 and M60, respectively). Hemodynamic parameters remained stable during the evaluate on period, no significant differences were observed between the groups in the respiratory variables and BIS, however, all animals presented respiratory acidosis. With the infusion of propofol associated or not with fentanyl the maintenance of the hemodynamic parameters was satisfactory with respiratory acidosis indicating, therefore, the use of mechanical ventilation FAPESP: 2013/09469-1

Foram utilizados 8 animais de seis a 12 meses de idade, holandeses, pesando de 84 a 124 kg. Os animais foram induzidos à anestesia com propofol na dose de 5 mg/kg IV e posicionados em decúbito lateral direito, onde permaneceram respirando espontaneamente ar ambiente. Ato contínuo, a manutenção anestésica foi realizada pela infusão contínua de propofol, administrado por meio de bomba de infusão em duas diferentes taxas 0,6 mg/kg/minuto IV (G06) e 0,8 mg/kg/minuto IV, (G08) durante 60 minutos. Os 8 animais foram anestesiados duas vezes, com uma semana de intervalo entre uma anestesia e outra.

Já a colheita das amostras para a dosagem plasmática do propofol foi realizada aos M15, M30, M45 e M60 minutos durante a infusão contínua do propofol e as demais colheitas foram realizadas após o termino da infusão com intervalos de 10 minutos por um período de 50 minutos (M70, M80, M90, M100 e M110 respectivamente). A infusão contínua de diferentes taxas de propofol não alterou as variáveis do BIS ao longo do tempo durante a infusão, também não causou alterações hemodinâmicas importantes, porém o G08 apresentou acidose respiratória indicando uso de ventilação controlada The aim of this study was to evaluate the bispectral index, hemodynamic and respiratory effects of continuous infusion of different rates of propofol in calves. Eight Holstein calves aging between six and 12 months and weighing 84-124 kg were used. They were induced to anesthesia with propofol at a dose of 5 mg / kg IV and positioned in right lateral recumbency, where they remained spontaneously breathing ambient air. Immediately thereafter, the anesthesia was maintained by continuous infusion of propofol administered with the aid of an infusion pump in two different rates 0.6 mg / kg / minute, IV (G06) and 0.8 mg / kg / minute, IV, (G08), during 60 minutes. The 8 animals were anesthetized twice, with one-week interval between anesthesia. The measurements of hemodynamic (HR, SAP, DAP, MAP, CO, CVP, mPAP, mPAPO, CI, SI, SVRI and PVRI), and respiratory parameters (ETCO2, f, SpO2, VTE, VME, and PFI), arterial blood gases (PaO2, PaCO2, SaO2, BE, pH and HCO3-) and bispectral index (BIS, EMG and SQI) were assessed before induction of anesthesia (MB), and 15, 30, 45 and 60 minutes after the start of continuous infusion of propofol (M15 , M30, M45 and M60, respectively). Sampling to measure plasma propofol was performed M15, M30, M45 and M60 minutes during continuous infusion of propofol and other samples were harvested after the end of infusion with 10-minute intervals during a period of 50 minutes (M70, M80, M90, M100 and M110 respectively). Continuous infusion of propofol at different rates did not alter the variables BIS over time and also did not cause significant hemodynamic changes, but the G08 had respiratory acidosis suggesting the use of controlled ventilation

Objective--To compare the anesthetic efficacy and adverse effects associated with peribulbar injection of ropivacaine (1 % solution) performed with and without ultrasound guidance (UG) in dogs. Animals--15 dogs without ophthalmologic abnormalities. Procedures--Each dog was sedated and anesthetized. A peribulbar injection of ropivacaine (1 % solution; 0.3 mL/kg) was performed with UG in 1 eye and without UG in the contralat-eral eye (control). For each eye, the intraocular pressure (IOP) immediately after eye centralization and number of punctures were recorded; ophthalmic complications, postinjection corneal sensitivity (determined by Cochet-Bonnet esthesiometry), durations of the sensory and motor blockades (the latter determined as the interval to restoration of the vestibulo-ocular reflex, pupillary light reflex, and conjugate eye movement), and blockade quality were assessed in both eyes following anesthetic recovery. Results--Needle placement was fully visualized in 8 of the 15 eyes injected with UG. For eyes injected with or without UG, there was no difference with regard to the number of punctures, postinjection corneal sensitivity, and sensory or motor blockade duration and quality; however, restoration of conjugate eye movement occurred later in control eyes. For eyes injected with UG, mean IOP was 18.6 mm Fig, compared with 23.3 mm Hg for control eyes. Incidence of subconjunctival hemorrhage was higher for control eyes; severity of chemosis and hyperemia varied over time within both groups of eyes. Conclusion and Clinical Relevance--In dogs, peribulbar injection of ropivacaine with UG is feasible in dogs and provides effective sensory and motor blockades similar to those achieved with conventional techniques.
