- Brief summaryDeep Neuromuscular Block (NMB) is associated with improved ratings of the quality of the surgical field in a number of surgical procedures including urological and gynecological surgeries.1 Recent data from the BLISS 3 trial additionally suggests that a deep NMB is associated with improved postoperative outcomes in terms of reduced pain in the PACU and on the ward.2 Consequently, the number of patients that receives a deep NMB has dramatically increased in our hospital. For example, currently all retroperitoneal surgeries in urology (nephrectomies, prostatectomies, lymph node removal), open eye surgeries and intracerebral vascular surgeries (eg., intracranial thrombectomies) are performed under deep NMB according to strict guidelines (ie. TOF zero, PTC 1-5).

Evidence demonstrating the benefit of a deep NMB or the absence of such benefit on outcomes apart from the subjective impressions of the surgeon is lacking. Additionally, there are no real-world data available of the deep NMB as all of the above mentioned benefits are obtained from well-controlled clinical trials. Hence, the current project aims to collect the characteristics of the deep NMB and expand the data collection to the post-anesthesia care unit and the ward. One example of a data gap is that we remain uniformed whether patients following a deep NMB experience less pain. This study aims to address the data gap on deep NMB by retrieval of objective data from LUMC database in patients undergoing elective surgery under deep NMB.
The main objective of the current retrospective analysis is to examine perioperative parameters in deep NMB. Historical control data of non-deep NMB cases will be examined for comparison.
