Abstract

|
Since neuromuscular blocking agents (NMBAs) were introduced to the surgical field, they have become almost mandatory for the induction and maintenance of anesthesia. However, resistance to NMBAs can develop in certain pathological states, such as central nerve injury, burns, and critical illnesses. During such pathological processes, quantitative and qualitative changes occur in the physiology of acetylcholine and the acetylcholine receptor (AChR) at the neuromuscular junction. Up-regulation of AChR leads to changes in the pharmacokinetics and pharmacodynamics of NMBA. As NMBA resistance may result in problems during anesthesia, it is of utmost importance to understand the mechanisms of NMBA resistance and their associations with pathological status to maintain adequate neuromuscular relaxation. This review presents the current knowledge of pharmacokinetic and pharmacodynamic changes and pathological status associated with NMBA resistance.
