This study’s aim was to assess the level of catecholamines, i.e., noradrenaline and dopamine, under oxygen debt conditions in the brain of experimental animals in which acute pancreatitis was experimentally induced. Catecholamines play the role of neurotransmitters and neuromediators. They are responsible for the regulation of motor and emotional processes, take part in the regulation of hormonal activities, sleep, wakefulness, concentration, attention, and learning processes. The experiment also determined the oxygen tension as an indicator of respiratory failure and the activity of amylase and lipase in the development of the inflammatory process. The animals on which the experiment was conducted were Wistar rats (140 animals) divided into 3 research groups: control (C) animals (n = 30), healthy (H) animals (n = 30), and operated (O) animals (n = 80). The determination of amylase, lipase, oxygen pressure, NA, and DO levels were performed at hours 2, 6, 12, 24, and 48 of the experiment. The animals in group C had an injection needle inserted to investigate only the effects of mechanical damage to the organs. On the other hand, the animals in group O had a 5% solution of sodium taurocholate introduced into the common bile-pancreatic duct. The research conducted shows that the most significant changes in NA and DO levels were observed on the first day of the experiment. The concentrations of the above catecholamines were statistically significantly correlated with the level of amylase in the blood. The peak of dopamine was observed between the 6th and 12th hours of the experiment, while the lowest concentration of noradrenaline was observed at the 6th hour of the experiment.
