“…However, the degree of neuromuscular block can be evaluated at several parts of anesthetized patients other than the adductor pollicis muscle; i.e., great toe [1,2], gastrocnemius muscle [3], corrugator supercilii or orbicularis oculi muscle [4,5], and the inferomedial part of the thigh [6,7].…”

“…A possible explanation for these observations is a greater proportion of type II muscle fibres within the vastus medialis compared with the AP. A more recent study, 91 using PMG, confirmed the shorter onset time, a less pronounced maximum effect, and a more rapid recovery of NMB after mivacurium 0.2 mg·kg -1 at the vastus medialis muscle than at the AP. However, the vastus medialis muscle should be considered an alternative monitoring site for those surgeries where there is no access to hand or foot muscles, taking into account the considerable pharmacodynamic differences compared with the AP.…”

Purpose:To review established techniques and to provide an update on new methods for clinical monitoring of neuromuscular function relevant to anesthesia.Source: A PubMed search of relevant article for the period 1985-2005 was undertaken, and bibliographies were scanned for additional sources. Principal findings:There is no substitute for objective neuromuscular monitoring; for research purposes, mechanomyography (MMG) is the gold standard; however, the most versatile method in the clinical setting is acceleromyography since it can be applied at various muscles and has a long track record of clinical utility. Kinemyography is valid to monitor recovery of neuromuscular transmission at the adductor pollicis muscle (AP), whereas phonomyography is easy to apply to various muscles and shows promising agreement with MMG. Monitoring of the corrugator supercilii muscle (CS) may be used to determine the earliest time for tracheal intubation as it reflects laryngeal relaxation better than monitoring at the AP. Recovery of neuromuscular transmission is best monitored at the AP, since it is the last muscle to recover from neuromuscular blockade (NMB). If train-of-four (TOF) stimulation is used, a TOF-ratio > 0.9 should be the target before awakening the patient. If surgery or the type of anesthesia necessitates NMB of a certain degree, e.g., TOF-ratio = 0.25, monitoring of muscles which best reflect the degree of NMB at the surgical site is preferable. Conclusion:Objective methods should be used to monitor neuromuscular function in clinical anesthesia. Acceleromyography offers the best compromise with respect to ease of use, practicality, versatility, precision and applicability at various muscles.The CS is the optimal muscle to determine the earliest time for intubation, e.g., for rapid sequence induction.

“…Given that the constituent ratio of type I and type II fibers is different among skeletal muscles [ 72 ], finding an ideal target muscle for PMG recording becomes important. Hemmerling’s team demonstrated that the vastus medialis muscle was also a desirable site for PMG recording by a piezoelectric microphone when some special operations hindered our access to the adductor pollicis muscle or the corrugator supercilii muscle, such as hand operations and neurosurgical operations [ 32 ].…”

Complications related to neuromuscular blockade (NMB) could occur during anesthesia induction, maintenance, and emergency. It is recommended that neuromuscular monitoring techniques be utilized perioperatively to avoid adverse outcomes. However, current neuromuscular monitoring methods possess different shortcomings. They are cumbersome to use, susceptible to disturbances, and have limited alternative monitoring sites. Phonomyography (PMG) monitoring based on the acoustic signals yielded by skeletal muscle contraction is emerging as an interesting and innovative method. This technique is characterized by its convenience, stable signal quality, and multimuscle recording ability and shows great potential in the application field. This review summarizes the progression of PMG on perioperative neuromuscular monitoring chronologically and presents the merits, demerits, and challenges of PMG-based equipment, aiming at underscoring the potential of PMG-based apparatuses for neuromuscular monitoring.
