“…The i-TOF device consists of a triaxial accelerometer, two poles for nerve stimulation, and wireless connection on a smartphone by application. another stand-alone device, the TOF WATCH SX, whose efficacy has already been shown by several works [12][13][14][15] . In our study, we mainly found an overlap between the two devices in recorded mean values of TOF ratio, TOF count, and PTC analyzed at time intervals for every phase of general anesthesia, although the i-TOF tends to an underestimation compared to TOF WATCH SX.…”

Neuromuscular block monitoring is recommended by international guidelines to improve myorelaxation during surgery and reduce the risk of postoperative residual curarization. We conducted a pilot study to verify the efficacy of i-TOF, a wireless neuromuscular monitoring device connectable to a smartphone, comparing it with TOF WATCH SX. We enrolled 53 patients who underwent general anesthesia. For each patient, we recorded by both devices, in different time intervals, train-of-four (TOF) count/ratio after induction to general anesthesia (TI0–TI3) and during recovery (TR0–TR3). Moreover, post-tetanic count (PTC) was evaluated during deep neuromuscular block (TP0–TP2). We noticed no significant differences between the devices in recorded mean values of TOF ratio, TOF count, and PTC analyzed at time intervals for every phase of general anesthesia, although the i-TOF tends to an underestimation compared to TOF WATCH SX. For each patient, data sessions were successfully recorded by a smartphone. This aspect could be relevant for clinicians in order to have a stored proof of good clinical practice to be added on anesthesiologist records. By our results, i-TOF demonstrates a comparable efficacy to TOF WATCH SX, suggesting that it could be a proven alternative to standard devices for neuromuscular block monitoring. Further studies are needed to confirm our findings.

“…Although whether the onset time of the adductor pollicis muscle is slower than that of the diaphragm is still in dispute, the recovery time of the adductor pollicis muscle is indeed slower than the diaphragm when NMB was administered [ 15 , 65 ]. Therefore, this muscle gained enough attention from scholars when considering new techniques for neuromuscular monitoring [ 66 , 67 ].…”

“…Despite its universal utilization in clinical settings, ACC is susceptible to artifacts and will probably generate an overrated block degree [ 12 , 14 ]. A conventional ACC-based apparatus records the monaxial movement of the target muscle; therefore, signal quality relies heavily on the posture of the recording sites [ 15 ]. Recently, ACC-based equipment capable of estimating the multiplanar movement of the thumb has been developed.…”

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.
