The  use  of  selected  schemes  for  anesthesia  in  dogs  laparotomnoy  operations  accompanied  by  inhibition  of 
consciousness, loss of tone of the skeletal muscles, and varying degrees of analgesia. Getting anesthesia in all groups was fast 
and held on average since the introduction 0,5-1min or early induction of anesthetic. It should be noted that the use of inhaled 
anesthetics recommended a gradual increase in concentration from 0.5% to 3% and the level of surgical anesthesia comes 
with 7-10 min. 
Doubtless  advantage  of  inhalation  anesthesia  is  its  manageability.  Since  the duration of  anesthesia  in  the  first  group 
determined the time of the inhalation. While the second and third groups, the duration of anesthesia amounted to 7,4 ± 0,56 
and 18,5 ± 1,6 minutes. The specified time frames tend not to perform the surgery because to maintain the proper level of 
anesthesia has repeatedly referred bolus use drugs. 
The  important  point  for  the  assessment  schemes  is  to  ensure  adequate  anesthesia  analgesic  effect.  None  of  the 
anesthetics used does not have a pronounced analgesic effect. However, the scheme include neuroleptic xylazine sedation 
allowed in all groups receive adequate analgesic and anesthetic effects expressed for abdominal surgery. 
For all schemes established anesthesia respiratory depression in dogs, it was most important in applying tiopenatu. In the 
second  and  third  groups  immediately  after  administration  of  anesthetic  watched  short-term  increase  in  respiratory  rate, 
followed by a short sleep and its subsequent oppression. Short-term increase in heart rate set in the first and second groups 
with subsequent inhibition of heart rate in all groups. 
For isoflurane inhalation anesthesia recovery of patients after cessation of inhalation occurs quickly, within minutes 2,45 
± 0,5, open the eyes of animals, begin to respond to external stimuli, raise the head. When using propofol present within 11,5 
± 1,1hv. Longest wake of patients continuing in the application of thiopental sodium to 55,2 ± 5,5min. 
Study basic life indicators in all groups of animals showing probable reduction in heart rate as during sedation and in 
anesthetized animals. Vodnos likely inhibition of cardiovascular 79,3 ± 0,9 beats / min and respiratory systems 16,7 ± 1,2 
breathing movements / min was in the third group of animals where tiopenat was used. The mentioned weakening of cardiac 
activity  and  respiration  caused  a  probable  decrease  arterial  blood  oxygen  saturation,  particularly  SpO2  rate  significantly 
decreased to 89,1 ± 2,4% compared to the state before anesthesia. 
The use of inhalation anesthesia using isoflurane likely accompanied by a weakening of the heart, but the heart rate was 
significantly higher than with tiopenatu. The rest of the studied parameters tended to decrease in the normal range. 
A similar reaction was in dogs on the use of propofol, significantly decreased heart rate, respiratory rate while SpO 2  and 
not decreased significantly. 

Action majority of anesthetics is accompanied by body temperature regulation established a probable decrease in body 
temperature when using propofol to ºC 37,2 ± 0,2 and 36,9 ± 0,5 tiopenatu ° C. Inhaled isoflurane temperature decreased but 
not significantly. 
The use of isoflurane inhalation anesthesia in the dogs scheme for surgical interventions on abdominal organs can reduce 
the threat of hemodynamic disorder, which is especially important in animals with cardiovascular failure, significant loss of 
blood, shock conditions. The advantages of izoflurane anesthesia is a high level of control of anesthesia, quickly change the 
depth of anesthesia, a long time to maintain anesthesia, a quick exit from the anesthesia, which creates prospects for further 
implementation in practice. 
The use of intravenous anesthetic injection ultrashort actions such as the proposed scheme propofol anesthesia also has a 
significant negative impact on hemodynamics in dogs by abdominal surgery. The shortcomings of the kind of anesthesia is 
need for continuous support for bolus or drip anesthesia, which complicates dosing and control. 
Application  of  tiopenatu  anesthesia  in  dogs  threatens  hemodynamic  disorders  in  patients,  significantly  inhibited  the 
activity of the respiratory and cardiovascular system that prevents its use in patients in critical condition, old animals and for 
cardiovascular disease.
