Cytomegalovirus (CMV) viremia occurs in 40% to 80% of CMV-seropositive (R+) recipients of allogeneic hematopoietic cell transplantation (HCT). The preemptive therapy (PET) strategy has reduced the risk of CMV end-organ disease (EOD) and associated mortality but may lead to substantial healthcare resource utilization (HCRU) and costs. Real-world data on the economic impact of PET is relevant for the evaluation of alternative strategies for CMV management.

Objectives: Neuromuscular blocking agents (NMBAs) have revolutionized the field of anesthesiology as they facilitate airway management and ensure optimal surgical conditions. Despite their beneficial and ubiquitous use during surgery, delayed or partial recovery from NMBAs, referred to as residual neuromuscular block (rNMB), is a common clinical problem. While it is well accepted that the antagonist sugammadex, compared to neostigmine, can more rapidly reverse rocuronium-induced NMB regardless of depth of block, the occurrence of rNMB for routinely used combinations of NMBAs with sugammadex or neostigmine has not yet been quantified or evaluated systematically.
