Evaluation of cardiorespiratory and biochemical effects of ketamine-propofol and guaifenesin-ketamine-xylazine anesthesia in donkeys (Equus asinus).

Objectives: To evaluate the cardiorespiratory and biochemical effects of ketamine-propofol (KP) or guaifenesin-ketamine-xylazine (GKX) anesthesia in donkeys.

Study Design: Prospective crossover trial.

Animals: Eight healthy, standard donkeys, aged 10 ± 5 years and weighing 153 ± 23 kg.

Fluid Heating System (SAF): effects on clinical and biochemistry parameters in dogs submitted to inhalatory anesthesia.

Purpose: To evaluate and describe immediate effects of the infusion of saline solution heated by SAF in bitches submitted to halothane anesthesia.

Methods: Thirteen bitches were employed and submitted to elective ovariohysterectomy in acclimatized operating room at 22 degrees C, allocated in two groups: GI, which received non-heated fluid and GII, which received fluid heated at 37 degrees C by SAF. The following parameters were evaluated in 30-minutes intervals (M0, M30, M60 and M90): rectal and cutaneous temperatures (TR and TC), cardiac and respiratory frequencies (HR and ), mean arterial blood pressure (MAP), serum concentration of urea, creatinin, serum activities of alanin aminotranspherasis (ALT), alkaline phosphatasis (ALP) and also hypnosis parameters.

Assessment of serum enzymatic markers of cardiomyocytes injury in female dogs submitted to ketamine S(+), atropin and xylazine association.

Purpose: To assessment of the aspartate aminotransferase (AST), creatine kinase (CK) and creatine kinase isoenzyme fraction MB (CK-MB) serum activity in female dogs anesthetized with ketamine S (+), atropine and xylazine in several associations.

Methods: Twenty three healthy female dogs randomly distributed in four groups named as GI (n=6), GII (n=6), GIII (n=6) and GIV (n=5) were treated respectively with atropine and ketamine S(+) (0.04 mg/kg; 10 mg/kg); ketamine S(+) (10 mg/kg); atropine, xylazine and ketamine S(+) (0.
