Diaphragmatic Movement

A bedridden patient with empyema presented for thoracoscopic decortication. During the procedure, despite a post-tetanic count (PTC) of 0 via calibrated quantitative neuromuscular monitoring, persistent diaphragmatic movement impaired operating conditions, so rocuronium was re-dosed. After surgery, the patient had 0 PTC. Sugammadex was titrated to achieve baseline neuromuscular strength, monitoring the effect of each 200-mg dose. Ultimately, 1200 mg was required to achieve baseline strength. We describe monitor troubleshooting, considerations with unexpectedly deep neuromuscular blockade, the importance of routine quantitative neuromuscular monitoring, and one strategy for sugammadex reversal in patients with profound paralysis outside of the standard dosing guidelines.

Abstract Editor’s Perspective What We Already Know about This Topic What This Article Tells Us That Is New Background Quantitative neuromuscular monitoring is required to ensure neuromuscular function has recovered completely at the time of tracheal extubation. The TOFscan (Drager Technologies, Canada) is a new three-dimensional acceleromyography device that measures movement of the thumb in multiple planes. The aim of this observational investigation was to assess the agreement between nonnormalized and normalized train-of-four values obtained with the TOF-Watch SX (Organon, Ireland) and those obtained with the TOFscan during recovery from neuromuscular blockade. Methods Twenty-five patients were administered rocuronium, and spontaneous recovery of neuromuscular blockade was allowed to occur. The TOFscan and TOF-Watch SX devices were applied to opposite arms. A preload was applied to the TOF-Watch SX, and calibration was performed before rocuronium administration. Both devices were activated, and train-of-four values were obtained every 15 s. Modified Bland–Altman analyses were conducted to compare train-of-four ratios measured with the TOFscan to those measured with the TOF-Watch SX (when train-of-four thresholds of 0.2 to 1.0 were achieved). Results Bias and 95% limits of agreement between the TOF-Watch SX and the TOFscan at nonnormalized train-of-four ratios between 0.2 and 1.0 were 0.021 and −0.100 to 0.141, respectively. When train-of-four measures with the TOF-Watch SX were normalized, bias and 95% limits of agreement between the TOF-Watch SX and the TOFscan at ratios between 0.2 and 1.0 were 0.015 and −0.097 to 0.126, respectively. Conclusions Good agreement between the TOF-Watch SX with calibration and preload application and the uncalibrated TOFscan was observed throughout all stages of neuromuscular recovery.

Background In most publications about myasthenia, monitoring neuromuscular blockade during anesthesia is recommended. In healthy patients, the relation of blockade between muscles has been established, but there is little information about the relation in myasthenic patients. Our objective was to investigate whether the relation between the orbicularis oculi and adductor pollicis muscles is the same in healthy patients and myasthenic patients. Methods After anesthesia was induced with 4-6 mg/kg thiopental and 2 microg/kg fentanyl, followed by 2% sevoflurane and 60% nitrous oxide in oxygen, 10 healthy patients and 10 myasthenic patients received 0. 025 and 0.01 mg/kg vecuronium, respectively. Neuromuscular monitoring was performed with use of accelerometry at the orbicularis oculi and the adductor pollicis muscles by stimulating the temporal branch of the facial nerve and the ulnar nerve. Results The relation of blockade between these two muscles was not the same in healthy patients and myasthenic patients: in healthy patients, the maximum neuromuscular blockade with 0.025 mg/kg vecuronium was less in the orbicularis oculi than in the adductor pollicis (median 72% vs. 91%; P < 0.05); in contrast, in myasthenic patients, the blockade with 0.01 mg/kg vecuronium was greater in the orbicularis oculi than in the adductor pollicis (median 96% vs. 62%; P < 0.05). Conclusion Neuromuscular monitoring at the orbicularis oculi may overestimate blockade in myasthenic patients. Extubation must be performed when the muscle most sensitive to neuromuscular blocking agents is recovered. Therefore, neuromuscular monitoring at the orbicularis oculi is recommended to avoid persistent neuromuscular blockade in patients with myasthenia gravis.

Abstract Background: Inadequate neuromuscular recovery might impair pulmonary function among adult patients who undergo general anaesthesia and might thus contribute to critical respiratory events in the post-anaesthesia care unit (PACU). The aim of this study to investigate whether critical respiratory events (CREs) that described in a modified Murphy’s criteria are significantly associated with residual neuromuscular blockade (RNMB).Method: A prospective cohort study from January to March 2017 from a tertiary hospital from Saudi Arabia for thirty adult patients over 18 years old scheduled for elective surgery under general anaesthesia with neuromuscular blocking drugs (NMBDs) were enrolled in the study. The Mann-Whitney U tests, Chi-Square tests and Independent-Samples T tests were used. The Train-of-four (TOF) ratios were measured upon arrival in the PACU by using Acceleromyography with TOF-Scan. Subjects’ demographics, perioperative data, and the occurrence of postoperative CREs in the PACU were recorded.Results: 26 (86.7%) patients out of thirty in the study has received Rocuronium as NMBDs while Neostigmine as a reversal drug with only 23 (76.7%). The incidence of RNMB (TOF ratio < 0.9) was in 16 patients (53.3%). The incidence of RNMB was significantly higher in female patients (p= 0.033), in patients who had not undergone quantitative neuromuscular monitoring before extubation (p= 0.046) and in patients with shorter duration of surgery (p= 0.001). Postoperative CREs occurred in twenty patients (66.7%), and there were significantly more of these CREs among patients with RNMB (P= 0.001). In addition, a statistically significant difference was observed in the occurrence of CREs according to body mass index (P= 0.047).Conclusion: This research showed that RNMB is a significant contributing factor to the development of critical respiratory events during PACU stay. Therefore, optimal antagonism of neuromuscular blockade and routine quantitative neuromuscular monitoring are recommended to reduce the incidence of RNMB.

ABSTRACT Context The duration of neuromuscular block with rocuronium is affected by old age as well as renal impairment. It would be helpful for anesthetists to know the variation in the block in elderly patients with renal failure and the significance of neuromuscular monitoring in this group. Aim The aim of our study is to investigate the neuromuscular effects of 0.6 mg/kg rocuronium under general anesthesia in young adults and elderly patients with or without renal failure. Study design Prospective randomized controlled study. Materials and methods Young and elderly 100 patients were divided into 4 groups of 25 each, with or without renal failure. General anesthesia with propofol 2 mg kg intravenous (iv), fentanyl 2 μg kg iv, and 60% N2O in O2 were given. Neuromuscular monitoring was started immediately after the induction of anesthesia and before the administration of muscle relaxant. After the stabilization of control responses, 0.6 mg kg rocuronium was injected intravenously. The onset time, time to achieve maximum block, and the recovery times were noted. Statistical analysis used The statistical analysis of the data from the study was performed with the Statistical Package for the Social Sciences (SPSS) software for Window Release 14.0. One-way analysis of variance, Bonferroni's, and chi-square test were used to compare patients’ characteristics. Results The duration of block as well as the recovery indices were significantly prolonged in the elderly compared to the young patients. Maximum prolongation was observed in the elderly group with renal failure. This underlines the importance of neuromuscular monitoring in these patients.

Reversal Agents

Neuromuscular blocking drugs, which include depolarizing and nondepolarizing drugs, are used to facilitate intubation and provide skeletal muscle relaxation during surgery and in the intensive care unit. The agents differ in their mechanism, duration of action, side-effect profile, and metabolism. Succinylcholine is the only depolarizing agent in clinic use and is typically used for emergent control of the airway, rapid sequence intubations, and short surgical procedures. The risk of hyperkalemia in certain clinical conditions and risk of malignant hyperthermia in susceptible individuals limit the use of succinylcholine in specific patient populations. Nondepolarizing agents vary in their duration of action, but all provide muscle relaxation for a longer duration than succinylcholine. Clinical effects of neuromuscular blocking drugs can be assessed with neuromuscular monitoring, although there is significant variability among providers in the regular use of neuromuscular monitoring. Reversal agents are used to restore neuromuscular transmission, as residual neuromuscular blockade after extubation has been associated with multiple adverse events, including hypoxemia, atelectasis, and aspiration. Sugammadex is an encapsulating agent capable of immediately reversing the effects of rocuronium-induced neuromuscular blockade that will likely impact the way many providers administer rocuronium and may decrease the future use of succinylcholine. This review contains 4 figures, 6 tables, and 41 references.

Postoperative Atelectasis

Background: postoperative atelectasis is a significant clinical problem during thoracic surgery with one-lung ventilation. Intraoperative deep neuromuscular blockade can improve surgical conditions, but an increased risk of residual paralysis may aggravate postoperative atelectasis. Every patient was verified to have full reversal before extubation. We compared the effect of deep versus moderate neuromuscular blockade on postoperative atelectasis quantitatively using chest computed tomography. Methods: patients undergoing thoracic surgery were randomly allocated to two groups: moderate neuromuscular blockade during surgery (group M) and deep neuromuscular blockade during surgery (group D). The primary outcome was the proportion and the volume of postoperative atelectasis measured by chest computed tomography on postoperative day 2. The mean values of the repeatedly measured intraoperative dynamic lung compliance during surgery were also compared. Result: the proportion of postoperative atelectasis did not differ between the groups (1.32 [0.47–3.20]% in group M and 1.41 [0.24–3.07]% in group D, p = 0.690). The actual atelectasis volume was 38.2 (12.8–61.4) mL in group M and 31.9 (7.84–75.0) mL in group D (p = 0.954). Some factors described in the lung protective ventilation were not taken into account and might explain the atelectasis in both groups. The mean lung compliance during one-lung ventilation was higher in group D (26.6% in group D vs. 24.1% in group M, p = 0.026). Conclusions: intraoperative deep neuromuscular blockade did not affect postoperative atelectasis when compared with moderate neuromuscular blockade if full reversal was verified.
