Anaesthesia for minimally invasive gastric and bowel surgery

It is of great importance that anaesthetic regimens match surgical procedures in regard to surgical time, in reducing organ dysfunction elicited by the anaesthesia and surgical trauma and by providing optimal post-operative pain treatment, leaving the possibility of early mobilization. New, rapidly eliminated anaesthetic drugs are, by virtue of their pharmacodynamic and pharmacokinetic profiles, optimal for use; combined with continuous thoracic epidurals with local anaesthetics and low-dose opioids, these drugs may permit reduction of various post-operative complications. Minimally invasive surgical techniques (e.g. laparoscopy) lead to serious anaesthesiological considerations concerning changes in haemodynamic and pulmonary parameters and intra-abdominal blood flow changes caused by increased intra-abdominal pressures. Few studies have evaluated whether these changes affect surgical outcome and whether or not different anaesthetic regimens influence relevant morbidity parameters. In future documentation it is important that controlled, well-designed clinical studies evaluate how the advantages from multimodal anaesthetic techniques improve relevant surgical outcome.
