“…We concede that conclusions from these findings are constrained by our relatively small and homogeneous study population. Our sample size was, nevertheless, similar to other comparative studies of two neuromuscular methods (n = 20-55) [4,6,14,15]. Moreover, we did not assess the increasing effect of the NMBA until complete deep block was attained, as indicated by a TOF count value of 0.…”

Neuromuscular monitoring is proposed to be part of standard anaesthetic monitoring to objectively assess the effects of non-depolarising neuromuscular blocking agents (NMBA) [1, 2]. NMBA's use during anaesthesia induction enables the optimisation of intubation conditions during conventional laryngoscopy [3]. The current clinical standard for neuromuscular monitoring is acceleromyography [4]. In most cases, an electrical stimulus is passed through adhesive electrodes that are placed over the ulnar nerve on the medial lower arm to stimulate the nerve (e.g., TOF-Scan, TOF-Watch). The stimulated motor response is then measured in the form of acceleration. The most commonly applied pattern is the train-of-four (TOF), in which the motor responses from the fourth and first stimuli are compared and expressed as a percentage, also

“…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 ]. Nevertheless, other muscles, such as the corrugator supercilii muscle, and the laryngeal muscle are frequently monitored in experimental and clinical practice [ 68 , 69 , 70 ].…”

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.

“…A previous study revealed that the average ± standard deviation (SD) time for first appearance of PTC after 0.6-mg•kg −1 rocuronium administration was 25.4 ± 8.6 minutes. 6 We considered a 30% difference in the recovery time observed between the 2 monitors to be clinically relevant. To detect the difference with an α value of 0.05 and a power of 0.8, it was necessary to include 19 patients in this study.…”

BACKGROUND:The commonly used acceleromyography (AMG)-based neuromuscular monitor TOF-Watch SX is no longer manufactured. Recently, a new portable electromyography (EMG)based neuromuscular monitor TetraGraph was introduced in clinical anesthesia. The aim of the study was to compare the responses obtained simultaneously from the abductor digiti minimi (ADM) muscle with TetraGraph and the adductor pollicis (AP) muscle with TOF-Watch SX during rocuronium-induced neuromuscular block. METHODS: Patients undergoing orthopedic surgery with general anesthesia were enrolled in this prospective, observational study. During total intravenous general anesthesia, train-of-four (TOF) responses following 0.9-mg•kg −1 rocuronium administration were monitored at the AP muscle with TOF-Watch SX and the ADM muscle with TetraGraph on the opposite arms. Sugammadex 2 mg•kg −1 was administered when both devices showed TOF counts (TOFCs) = 2. The primary outcome was time from rocuronium administration to first appearance of posttetanic count (PTC) response (first PTC). The secondary outcomes were baseline TOF ratios (TOFRs), onset time, time to first reappearance of TOFC = 1 (time to TOFC1), time to first reappearance of TOFC = 2 (time to TOFC2), and time from sugammadex administration to TOFR ≥0.9 with TetraGraph or to normalized TOFR ≥0.9 with TOF-Watch SX (recovery time). We used paired t test and Wilcoxon signed-rank test to analyze parametric and nonparametric data, respectively. P <.05 defined statistical significance. RESULTS: A total of 20 patients were analyzed. The baseline TOFRs were significantly higher with TOF-Watch SX than with vs 100 [98][99][100][101]; P = .0002). The time to first PTC (minutes) (31.7 ± 9.6 vs 41.1 ± 12.3; P < .001), time to TOFC1 (minutes) (48.0 ± 12.7 vs 58.8 ± 19.2; P < .001), time to TOFC2 (minutes) (56.2 ± 15.7 vs 74.2 ± 23.7; P < .001), and recovery time (seconds) (61.5 [32-148] vs 75.5 [94-102]); P = .043) were significantly faster with TOF-Watch SX than with TetraGraph. There were no significant differences in onset time. CONCLUSIONS: TOF-Watch SX overestimated recovery from rocuronium-induced neuromuscular block compared with TetraGraph.
