Low Pressure Pneumoperitoneum and Deep Neuromuscular Block vs. Standard During RARP to Improve Quality of Recovery; a Randomized Controlled Study.

Intra-abdominal pressure (IAP) needed to create sufficient workspace during laparoscopic surgery affects the surrounding organs with ischemia-reperfusion injury and a systemic immune response. This effect is related to postoperative recovery, pain scores, opioid consumption, bowel function recovery, morbidity and possibly mortality. In clinical practice standard pressures of 12-16mmHg are applied instead of the lowest possible IAP, but accumulating evidence shows lower pressure pneumoperitoneum (PNP) (6-8mmHg) to be non-compromising for sufficient workspace, when combined with deep neuromuscular blockade (NMB) in a vast majority of patients. Therefore, low impact laparoscopy, meaning low pressure PNP facilitated by deep NMB, could be a valuable addition to Enhanced Recovery After Surgery (ERAS) Protocols. The use of low pressure PNP may also reduce hypoxic injury and the release of DAMPs and thereby contributing to a better preservation of innate immune function which may help to reduce the risk of infectious complications. The participants will be randomly assigned to one of the experimental groups with low impact laparoscopy or one of the control groups with standard laparoscopy.
