[Various effects of secretin and pentagastrin on peripheral venous blood gas analysis].
Until recently, vasomotor effects of gastrointestinal polypeptide hormones have been observed primarily in animal experimentation. 33 volunteers were observed to survey the influence of secretin (1 CU/bw./h) and pentagastrin (0.75 micrograms/bw/h) on peripheral blood gas concentrations and on the acid/base balance. Compared to a control group, secretin caused a significant increase in pO2 and in O2 saturation (p less than 0.05). In contrast to secretin, pentagastrin caused a significant decrease in the pO2 as well as in the O2 saturation (p less than 0.05) pCO2, pH and HCO3 were not significantly affected by either secretin or pentagastrin. These results can be interpreted as possible direct vasodilatative/constrictive as well as local metabolic effects of secretin and pentagastrin.
