[Ganglionic blockers in abdominal surgery: facts and hypotheses. I. Benzohexonium and motor function of the gastrointestinal system in the early postoperative period].

The method of registration of the intraluminal pressure was used to study the function of the stomach, small intestine and sigmoid colon under conditions of partial ganglionic blockade in the first days after truncal vagotomy and resection of the stomach. It was found that benzohexonium in doses 0.1-0.3 mg/kg failed to substantially decrease the frequency of early functional motor-evacuation disorders of the "operated" stomach, but the results of using N-cholinolytic was better after truncal vagotomy than after resection of the stomach. Benzohexonium in doses 0.1-0.2 mg/kg failed to considerably stimulate the motor function of the small intestine while the doses of 0.3-0.4 mg/kg resulted in a decrease of its contractile activity. No reliable changes in the qualitative and quantitative parameters of the sigmoid colon motor function were found against the background of ganglionic blockade. So, for prevention and correction of early postoperative motor-evacuation disorders of the gastrointestinal tract the ganglionic blockade with N-cholinolytics should not be taken as a method of choice or a variant of monotherapy.

Effects of adrenergic neuron and ganglion blockers on hemodynamics and plasma catecholamine levels after corticosteroids during hemorrhagic shock in the dog.

The involvement of adrenergic mechanisms in the ability of massive doses of methylprednisolone to potentiate the vasodilatory effects of phenoxybenzamine during controlled hemorrhagic shock was investigated. Dogs were subjected to ligation of the adrenals and, with the exception of the controls, were pretreated with either hexamethonium or bretylium. Despite careful surgery, the adrenal ligation, per se, failed to alter the concentration of plasma catecholamines. Hexamethonium and bretylium, on the other hand, both decreased the levels of plasma catecholamines: noradrenaline to a greater extent than adrenaline. Methylprednisolone was almost ineffective after ganglionic or adrenergic neuron blockade. Furthermore, the degree of vasodilation after methylprednisolone and phenoxybenzamine seemed to correlate better with plasma noradrenaline than with adrenaline. These findings indicate that the ability of methylprednisolone to induce vasodilation in the presence of adrenergic alpha-receptor blockade in hypovolemic shock in the dog relies on an intact release of noradrenaline from postganglionic adrenergic nerve terminals.
