    PURPOSE: To assess the bispectral index (BIS) and recovery in calves anesthetized with xylazine, midazolam, ketamine and isoflurane and subjected to CRI of lidocaine. METHODS: Xilazine was administered followed by ketamine and midazolam, orotracheal intubation and maintenance on isoflurane using mechanical ventilation. Lidocaine (2 mg kg-1 bolus) or saline (0.9%) was administered IV followed by a CRI (100 μg kg-1 minute-1) of lidocaine (L) or saline (C). Were recorded BIS, heart rate (HR), mean arterial pressure (MAP) and rectal temperature (RT) before administration of premedication (TB) and 15 minutes after (TX), before administering lidocaine (T0) and 20, 40, 60 and 80 minutes after the start of the CRI. Time do sternal recumbency (SRE) and standing (ST) and plasma lidocaine concentration also evaluated. RESULTS: In both treatments BIS decreased significantly at all times compared to TB. TX was higher than the subsequent times. HR decreased from baseline at all times and decreased from T40 in L compared to C. SRE was higher in L compared to C. CONCLUSIONS: Bispectral index values were consistent with the degree of hypnosis of the animals. Lidocaine did not potentiate isoflurane anesthesia assessed by BIS in unstimulated calves anesthetized with constant E´Iso. Lidocaine increased the time to sternal recumbency.3016772Haga, H.A., Dolvik, N.I., Evaluation of the bispectral index as an indicator of degree of central nervous system depression in isoflurane-anesthetizes horses (2002) Am J Vet Res, 63 (3), pp. 438-442Henao-Guerreno, P.N., McMurphy, R., Kukanich, B., Hodgson, D.S., Effect of morphine on the bispectral index during isoflurane anesthesia in dogs (2009) Vet Anaesth Analg, 36 (2), pp. 133-143Rosow, C., Manberg, P.J., Bispectral index monitoring (2001) Anesthesiol Clin North Am, 19 (4), pp. 947-966Antognini, J.F., Wang, X.W., Cartens, E., Isoflurane anaesthetic depth in goats monitored using the bispectral index of the electroencephalogram (2000) Vet Res Commun, 24 (6), pp. 361-370Martin-Cancho, M., Lima, J.R., Luis, L., Crisóstomo, V., Ezquerra, L.J., Carrasco, M.S., Usón-Gargallo, J., Bispectral index, spectral edge frequency 95%, and median frequency recorded for various concentration of isoflurane and sevoflurane in pigs (2003) Am J Vet Res, 64 (7), pp. 866-873March, P.A., Muir, W.W., Use of the bispectral index as a monitor of anesthetic depth in cats anesthetized with isoflurane (2003) Am J Vet Res, 64 (12), pp. 1534-1541Campagnol, D., Teixeira Neto, F.J., Monteiro, E.R., Beier, L.S., Aguiar, J.A., Use of bispectral index to monitor depth of anesthesia in isoflurane-anesthetized dogs (2007) Am J Vet Res, 68 (12), pp. 1300-1307Garcia-Pereira, F.L., Greene, A.S., Keegan, R.D., McEwen, M.M., Tibary, A., Effects of intravenous butorphanol on cardiopulmonary function in isoflurane-anesthetized alpacas (2007) Vet Anesth Analg, 34 (4), pp. 269-274Muir, W.W., Wiese, A.J., March, P.A., Effects of morphine, lidocaine, ketamine, and morphine-lidocaine-ketamine drug combination on minimum alveolar concentration in dogs anesthetized with isoflurane (2003) Am J Vet Res, 64 (9), pp. 1155-1160Vesal, N., Spadavecchia, C., Steiner, A., Kirscher, F., Levionnois, O.L., Evaluation of the isoflurane-sparing effects of lidocaine infusion during umbilical surgery in calves (2011) Vet Anaest Analg, 38 (5), pp. 451-460Dzikiti, T.B., Hellebrekers, P., Van Dijk, P., Effects of intravenous lidocaine on isoflurane concentration, physiological parameters, metabolic parameters and stress-related hormones in horses undergoing surgery (2003) J Vet Med A, 50 (4), pp. 190-195Pypendop, B.H., Ilkiw, J.E., The effects of intravenous lidocaine administration on the minimum alveolar concentration of isoflurane in cats.

    ABSTRACT One of the current barriers proposed to avoid possible medication errors, and consequently harm to patients, is the medication reconciliation, a process in which drugs used by patients prior to hospitalization can be compared with those prescribed in the hospital. This study describes the results of a pharmacist based reconciliation conducted during six months in clinical units of a university hospital. Fourteen patients (23.33%) had some kind of problem related to medicine. The majority (80%) of medication errors were due to medication omission. Pharmaceutical interventions acceptance level was 90%. The results suggest that pharmacists based reconciliation can have a relevant role in preventing medication errors and adverse events. Moreover, the detailed interview, conducted by the pharmacist, is able to rescue important information regarding the use of drugs, allowing to avoid medications errors and patient injury
