[Assessment of mesenteric anesthesia in abdominal interventions].

This study had been undertaken for the purpose of assessment of mesenteric anaesthesia and its effects on cardiovascular changes during abdominal surgery performed under general anaesthesia (neuroleptanaesthesia). Investigations were applied to 50 patients gastrectomized for gastric ulcer (Billroth II). The patients were subdivided into two comparable groups, with 25 in each of them. Group I had been without mesenteric anaesthesia and Group II with mesenteric anaesthesia according to Finsterer. Average arterial blood pressure, cardiac output, and heart rate were measured prior to anaesthesia and intraoperatively. General anaesthesia, according to our results, led to statistically significant decline of cardiac output (p less than 0.001). Continuous drop in cardiac output was caused also by surgical manipulations in the abdominal cavity of patients without mesenteric anaesthesia. However, mesenteric anaesthesia according to Finsterer resulted in significant rise (p less than 0.001) of cardiac output, as compared to preoperative values. Hence, if undesired circulatory responses are to be avoided in abdominal surgery, mesenteric anaesthesia appears to be just as important as a careful surgical technique which should be tissue-sawing.
