Avaliação de parâmetros cardiovasculares, ventilatórios e hemogasométricos de coelhos anestesiados com isofluorano ou sevofluorano e submetidos à ventilação espontânea ou controlada a volume

The volume-controlled mechanical ventilation and spontaneous ventilation, through haemogasometric, cardiovascular and spirometry variables were evaluated. Twenty-eight rabbits were distributed into two groups: GIVC (isoflurane and volume-controlled ventilation), GIVE (isoflurane and spontaneous ventilation), GSVC (sevoflurane and volume-controlled ventilation) and GSVE (sevoflurane and spontaneous ventilation). Induction was performed by mask with isoflurane (GIVE and GIVC) or sevoflurane (GSVE and GSVC) at 1.5 MAC in 100% oxygen. To maintain anesthesia, MAC was reset to 1. In GIVC and GSVC groups, rocuronium was administered at a dose of 0.6 mg/kg followed by its continuous infusion (0.6 mg/kg/h). In GSVE and GIVE, 0.9% NaCl was administered instead of rocuronium. Controlled ventilation was started by adjusting the capnometry in order to obtain values between 35 and 45 mmHg. Parameters were measured 60 minutes after induction of anesthesia (M0), 15 minutes after the bolus of rocuronium or 0.9% NaCl (M15) and every fifteen minutes (M30, M45 and M60). Hypercapnia and acidosis was evident in GIVC, GSVC and GSVE. We concluded that the volume-controlled mechanical ventilation was not able to maintain normocapnia in rabbits, producing acidosis in them, especially when using sevoflurane. The use of isoflurane showed greater stability than the sevoflurane anesthetic in the species studied.

Anestesia total intravenosa (ATI) para herniorrafias umbilicais em bezerros

The total intravenous anesthesia (TIVA) is an option for some surgeries in bovines for fields. The aim of this study was to evaluate blood gases effects, cardiorespiratory and glycemia on calves submitted the umbilical herniorraphy. We used eight calves aged from 9 ± 4 months, weighting 111 ± 43 kg. The animals were pre-treated with xylazine (0.05 mg/kg IV) and after 15 minutes was administered ketamine (2.0 mg/kg IV) followed by the continuous infusion of xylazine (0.05 mg/ml), guaifenesin (50 mg/mL) and ketamine (1mg/ml) at a rate of infusion of 2mL/kg/hour. The blood gases and glucose samples were collected immediately before the MPA (MB) and the 5, 40 and 80 after the starting of TIVA (M5, M40 e M80). The other variables were measured in MB, 15 minutes after the MPA (Mx) and every 10 minutes after the starting of TIVA, entiring 80 minutes. The heart rate was higher in MB than in the other stages (p <0.05) and respiratory rate increased in M20 and M50 compared to MB and Mx (p <0.05). The PvCO2 increased while PaO2 decreased in M40 and M80, for MB (p <0.05), PVCO2 in M80 was lower than in MB (p <0.05). The pHv was smaller in M80 than M5 and MB (p <0.05), and HCO3 was lower in MB (p <0.05) compared to the others. The glucose was higher in M40 and M80 and M5 for MB (p <0.05). The recovery time was 152 ± 60 minutes after the end of the administration of the infusion of anesthetics. It was conclude that the anesthetic technique employed promoted respiratory depression, increased blood glucose and prolonged period of anesthetic recovery in calves.
