Br J Anaesth 2024; 132:107-115. [PMID: 38036323 DOI: 10.1016/j.bja.2023.10.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 10/16/2023] [Accepted: 10/19/2023] [Indexed: 12/02/2023] Open
Abstract
BACKGROUND Residual neuromuscular block is associated with increased patient morbidity. Therefore prevention of residual neuromuscular block is an important component of general anaesthesia where neuromuscular blocking agents are used. Whereas sugammadex improves reversal based on neuromuscular twitch monitoring parameters, there have been no prospective, adequately powered definitive studies demonstrating that sugammadex is also associated with less patient morbidity. METHODS We performed a systematic review of randomised trials comparing sugammadex with anticholinesterase-based reversal or placebo reversal that reported important patient outcomes beyond the postanaesthesia care unit. RESULTS We identified 43 articles, including 5839 trial participants. Only one trial reported days alive and out of hospital to 30 days (DAOH-30), which showed that the number of DAOH-30 was similar in those allocated to sugammadex compared with neostigmine-based reversal (25 days [19-27] vs 24 days [21-27], median difference 0.00 [-2.15 to 2.15]). Pooled analyses of data from 16 trials showed an estimated odds ratio (OR) for postoperative pulmonary complications of 0.67 (95% confidence interval 0.47-0.95) with sugammadex use. Pooled analysis showed that pneumonia (eight trials OR 0.51 [0.24-1.01] with sugammadex use), hospital length of stay (23 trials, mean difference -0.31 [-0.84 to 0.22] with sugammadex use), and patient-reported quality of recovery (11 trials, varied depending on metric used) are similar in those allocated to sugammadex vs control. The difference seen in mortality (11 trials, OR 0.39 [0.15-1.01] with sugammadex use) would be considered to be clinically significant and warrants further investigation, however, the rarity of these events precludes drawing definitive conclusions. CONCLUSION Although few trials reported on DAOH-30 or important patient outcomes, sugammadex is associated with a reduction in postoperative pulmonary complications, however, this might not translate to a difference in hospital length of stay, patient-reported quality of recovery, or mortality.

Abstract
Background and Aims The postoperative residual neuromuscular block (PRNB) has a significant impact on patient safety and well-being, but continues to remain underestimated. Objective evaluation of handgrip strength using a force dynamometer can be useful to identify postoperative muscle weakness. Material and Methods Thirty-two American Society of Anesthesiologists (ASA) class I and II patients who received general anesthesia were included. Patients were extubated after the train-of-four (TOR) ratio (TOFR) was >0.90 and the clinical criteria for motor power recovery were judged as adequate. The measurements of handgrip strength and peak expiratory flow rate (PEFR) were obtained at baseline, 15 min after extubation, and 1, 2, and 4 h postoperatively. The incidence of significant decline from baseline (>25%) was determined. The correlation between handgrip strength and PEFR was assessed using Spearman correlation. The time to return to baseline for muscle grip strength and PEFR was performed using Kaplan-Meier survival analysis. A P value of 0.05 was considered significant for all tests. Results The incidence of the significant decline in handgrip strength from baseline was 100% at 15 and 60 min, 76% at 2 h, and 9.4% at 4 h. There was a strong correlation between muscle grip strength and PEFR (0.89, P < 0.001). None of the patients exhibited the potential complications of PRNB. (PRMB in abstract. It should be uniform) The mean time to return to the baseline value of muscle grip strength was 3.8 h (95% confidence interval [CI] 3.6-3.9), and the mean time to return to baseline for PEFR was 3.2 h (95% CI 2.9-3.4 h). Conclusion Objective assessment of muscle grip strength using a force dynamometer has the potential to be a new objective metric to monitor postoperative muscle weakness.

Abstract
PURPOSE Stiff person syndrome (SPS), an autoimmune disease that manifests with episodic muscle rigidity and spasms, has anesthetic considerations because postoperative hypotonia may occur. This hypotonia has been linked to muscle relaxants and volatile anesthetics and may persist in spite of neostigmine administration and train-of-four (TOF) monitoring suggesting full reversal. We present a patient with SPS who experienced hypotonia following total intravenous anesthesia (TIVA), which was promptly reversed with sugammadex. These observations are considered in light of the relevant medical literature. CLINICAL FEATURES A 46-yr-old female patient with SPS underwent breast lumpectomy and sentinel node biopsy. Anesthesia consisted of TIVA (propofol/remifentanil) with adjunctive administration of rocuronium 20 mg to obtain adequate intubating conditions. Despite return of the TOF ratio to 100% within 30 min, hypotonia was clinically evident at conclusion of surgery two hours later. Sugammadex 250 mg reversed residual muscle relaxation permitting uneventful extubation. A literature review identified six instances of postoperative hypotonia (TIVA, n = 3; volatile anesthetics, n = 3) in spite of neostigmine administration (n = 2) and TOF monitoring suggesting full reversal (n = 4). CONCLUSIONS Patients with SPS may show hypotonia regardless of general anesthetic technique (TIVA vs inhalational anesthesia), which can persist despite recovery of the TOF ratio and may be more effectively reversed by a chelating agent than with an anticholinesterase. If general anesthesia is required, we suggest a cautious approach to administering muscle relaxants including using the smallest dose necessary, considering the importance of clinical assessment of muscle strength recovery in addition to TOF monitoring, and discussing postoperative ventilation risk with the patient prior to surgery.

Abstract
Background and Aims: Residual neuromuscular block continues to be a significant postoperative complication despite neuromuscular monitoring. This study aims to determine the applicability of a hand-held forced dynamometer for hand grip strength assessment as an objective measure of residual muscle weakness. Methods: The study included patients undergoing surgery under general anaesthesia. A demonstration was given to the patient on the usage of a dynamometer for handgrip strength and a peak expiratory flow meter for peak expiratory flow rate (PEFR) and baseline values were recorded. The parameters were monitored at 15 minutes post-extubation and again at intervals of 15 minutes until one hour, half-hourly until four hours, and hourly until six hours post-operatively. Paired t-test was used for comparison of baseline muscle strength and PEFR with the parameters at different time points. Association between muscle strength and PEFR was tested with the Pearson-correlation test. Results: Muscle strength was 50 to 60%, 75% and 100% of baseline at 15, 45 and 210 minutes after extubation, respectively. PEFR was 50 to 60%, 75% and 100% of baseline at 15, 60 and 180 minutes after extubation. The Pearson-correlation test established a positive correlation between handgrip strength and PEFR (correlation-coefficient 0.86). Conclusion: A significant reduction in the postoperative muscle strength can be detected using an objective forced dynamometer to measure handgrip strength even when train of four count has returned to unity and even when there are no clinical signs of muscle weakness. The residual muscle weakness is significant enough to affect the PEFR in the postoperative period.

Abstract
Background Systemic anesthetic management of patients with mitochondrial disease requires careful preoperative preparation to administer adequate anesthesia and address potential disease-related complications. The appropriate general anesthetic agents to use in these patients remain controversial. Case presentation A 54-year-old woman (height, 145 cm; weight, 43 kg) diagnosed with mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes underwent elective cochlear implantation. Infusions of intravenous remimazolam and remifentanil guided by patient state index monitoring were used for anesthesia induction and maintenance. Neither lactic acidosis nor prolonged muscle relaxation occurred in the perioperative period. At the end of surgery, flumazenil was administered to antagonize sedation, which rapidly resulted in consciousness. Conclusions Remimazolam administration and reversal with flumazenil were successfully used for general anesthesia in a patient with mitochondrial disease.

Abstract
INTRODUCTION Early mobilization after cancer surgery is generally recommended. However, the effects of postoperative resistance exercise during a hospital stay have been rarely investigated. This study aimed to clarify the effects of resistance exercise after laparoscopic surgery on exercise tolerance and skeletal muscle mass in geriatric patients with gastrointestinal cancer. METHODS This single-center retrospective observational study included patients with gastrointestinal cancer who admitted for laparoscopic surgery. Exercise tolerance and skeletal muscle mass were assessed using a six-minute walking test (6MWT) and skeletal muscle index (SMI) at admission and discharge, respectively. Intergroup comparisons of absolute changes in 6MWT and SMI were analyzed by the unpaired t-test or Mann-Whitney U test according to whether resistance exercise was performed or not. Multivariable linear regression analyses were used to analyze the association of resistance exercise with changes in 6MWT and SMI. The analyses were adjusted for age, sex, cancer stage, postoperative complication, and preoperative exercise tolerance and skeletal muscle mass. RESULTS Altogether, 66 patients (mean age 69.9 years; 60.6% men) were recruited. Of them, 72.7% performed the resistance exercise and started at a median of 4.5 postoperative days. There were no significant intergroup differences in absolute changes in the 6MWT and the SMI (p = 0.153, p = 0.476, respectively). Multivariable linear regression analysis showed that resistance exercise was independently and positively associated with the 6MWT at discharge (β = 1.70, 95% confidence interval, 1.88 to 71.09) and did not significantly contribute to the SMI at discharge (95% confidence interval, -0.21 to 0.27). CONCLUSION Resistance exercise may enhance the improvement in postoperative exercise tolerance in geriatric patients with gastrointestinal cancer who underwent laparoscopic surgery.

Abstract
INTRODUCTION Despite the use of quantitative neuromuscular monitoring together with the administration of reversal drugs (neostigmine or sugammadex), the incidence of residual neuromuscular blockade defined as a train-of-four ratio (TOFr) <0.9 remains high. Even TOFr >0.9 cannot ensure adequate recovery of neuromuscular function when T1 height is not recovered completely. Thus, a mathematical correction of TOFr needs to be applied because the return of a normal TOFr can precede the return of a normal T1 twitch height. On the other hand, different muscles have different sensitivities to neuromuscular blockade agents; thus, complete recovery of one specific muscle group does not represent complete recovery of all other muscles. Therefore, our study aims to assess the muscle strength recovery of respiratory-related muscle groups by ultrasound and evaluate global strength using handgrip dynamometry in the early postoperative period when TOFr=0.9 and corrected TOFr (cTOFr)=0.9 with comparison of neostigmine versus sugammadex as reversal drugs. METHODS AND ANALYSIS This study will be a prospective, single-blinded, randomised controlled trial involving 60 patients with American Society of Anesthesiologists physical status I-II and aged between 18 and 65 years, who will undergo microlaryngeal surgery. We will assess geniohyoid muscle, parasternal intercostal muscle, diaphragm, abdominal wall muscle and handgrip strength at four time points: before anaesthesia, TOFr=0.9, cTOFr=0.9 and 30 min after admission to the post anaesthesia care unit. Our primary objective will be to compare the effects of neostigmine and sugammadex on the recovery of muscle strength of different muscle groups in the early postoperative period when TOFr=0.9 and cTOFr=0.9. The secondary objective will be to observe the difference of muscle strength between the time points of TOFr=0.9 and cTOFr=0.9 to find out the clinical significance of cTOFr >0.9. ETHICS AND DISSEMINATION The protocol was reviewed and approved by the Ethics Committee of The First Affiliated Hospital, Sun Yat-sen University. The findings will be disseminated to the public through peer-reviewed scientific journals. TRIAL REGISTRATION NUMBER ChiCTR2000033832.

Abstract
The use of anticholinesterases to reverse residual neuromuscular block at the end of surgery became routine practice in the 1950s. These drugs could only be used when recovery from block was established [two twitches of the train-of-four (TOF) count detectable] and concern was expressed about their cholinergic side-effects. By the 1990s, it was recognized that failure to reverse residual block adequately to a TOF ratio (TOFR) >0.7 was associated with increased risk of postoperative pulmonary complications (POPCs) following the long-acting non-depolarizing neuromuscular blocking drug (NDNMBD) pancuronium. By 2003, and the introduction of acceleromyography, a TOFR ≥0.9 was considered necessary to protect the airway from aspiration before tracheal extubation. It was also considered that four, not two, twitches of the TOF should be detectable before neostigmine was given. Use of any NDNMBD was subsequently shown to be associated with increased risk of POPCs, but it was thought that neostigmine reduced that risk. Recently, there has been conflicting evidence that use of neostigmine might increase the incidence of POPCs. Although sugammadex has been shown to rapidly reverse profound neuromuscular block from aminosteroidal agents, there is currently no evidence that sugammadex is superior to neostigmine in its effect on POPCs. Other new antagonists, including cysteine to degrade CW002 and calabadion 1 and 2 to antagonize aminosteroidal and benzylisoquinolium NDNMBDs, are being studied in preclinical and clinical trials. Quantitative neuromuscular monitoring is essential whenever a NDNMBD is used to ensure full recovery from neuromuscular block.

Abstract
OBJECTIVE Some anaesthetists are convinced that a long interval since the last relaxant dose may be sufficient to recover from anaesthesia without a pharmacological reversal. We intended to demonstrate that the dosing pattern of rocuronium could not predict the necessity of reversal. METHODS In a cohort analysis, we retrospectively analysed 180 anaesthesia records of adult patients who underwent elective surgical interventions in general anaesthesia and tracheal intubation with rocuronium-induced neuromuscular blockade. The extracted records were divided to 3 post hoc groups of 60 each, according to the reversal method employed at the end of anaesthesia: group N with neostigmine, group S with sugammadex and group Z without pharmacological reversal. All cases were terminated after achieving a train of four ratio of 0.9. Dosing patterns of rocuronium were compared by applying a novel pharmacometric calculation method, residual drug activity coefficient (RDAC), which employs both the administered individual drug doses in mg kg-1 and the timing of each drug administration in relation to the time of extubation. The rocuronium dosing pattern was correlated with the employed method of neuromuscular blockade reversal. RESULTS The dosing for rocuronium in patients without pharmacological reversal was lower than that in both reversal agent groups (n=0.58±0.21, S=0.58±0.17 and Z=0.47±0.17), but there was still a large overlap in the RDAC. CONCLUSION The dosage profile of rocuronium alone cannot predict the possibility to refrain from pharmacological reversal.

Abstract
Sugammadex, a modified gamma-cyclodextrin, has changed clinical practice of neuromuscular reversal dramatically. With the introduction of this selective relaxant binding agent, rapid and reliable neuromuscular reversal from any depth of block became possible. Sugammadex can reverse neuromuscular blockade without the muscarinic side effects typically associated with the administration of acetylcholinesterase inhibitors. However, what remained unchanged is the incidence of residual neuromuscular blockade. It is known that sugammadex cannot always prevent its occurrence, if appropriate dosing is not chosen based on the level of neuromuscular paralysis prior to administration determined by objective neuromuscular monitoring. Alternatively, excessive doses of sugammadex administered in an attempt to ensure full and sustained reversal may affect the effectiveness of rocuronium in case of immediate reoperation or reintubation. In such emergent scenarios that require onset of rapid and reliable neuromuscular blockade, the summary of product characteristics (package insert) recommends using benzylisoquinolinium neuromuscular blocking agents or a depolarizing agent. However, if rapid intubation is required, succinylcholine has a significant number of side effects, and benzylisoquinolinium agents may not have the rapid onset required. Therefore, prior administration of sugammadex introduces a new set of potential problems that require new solutions. This novel reversal agent thus presents new challenges and anesthesiologists must familiarize themselves with specific issues with its use (e.g., bleeding risk, hypermagnesemia, hypothermia). This review will address sugammadex administration in such special clinical situations.

Abstract
BACKGROUND In the postoperative period, immediate recovery of muscular power is essential for patient safety, but this can be affected by anaesthetic drugs, opioids and neuromuscular blocking agents (NMBA). In this cohort study, we evaluated anaesthetic and patient-related factors contributing to reduced postoperative muscle power and pulse oximetric saturation. METHODS We prospectively observed 615 patients scheduled for minor surgery. Premedication, general anaesthesia and respiratory settings were standardized according to standard operating procedures (SOP). If NMBAs were administered, neuromuscular monitoring was applied to establish a Train of four (TOF)-Ratio of >0.9 before extubation. After achieving a modified fast track score > 10 at 4 time points up to 2 h postoperatively, we measured pulse oximetric saturation and also static and dynamic muscle power, using a high precision digital force gauge. Loss of muscle power in relation to the individual preoperative baseline value was analysed in relation to patient and anaesthesia-related factors using the T-test, simple and multiple stepwise regression analysis. RESULTS Despite having achieved a TOF ratio of >0.9 a decrease in postoperative muscle power was detectable in most patients and correlated with reduced postoperative pulse oximetric saturation. Independent contributing factors were use of neuromuscular blocking agents (p < 0.001), female gender (p = 0.001), TIVA (p = 0.018) and duration of anaesthesia >120 min (p = 0.019). CONCLUSION Significant loss of muscle power and reduced pulse oximetric saturation are often present despite a TOF-Ratio > 0.9. Gender differences are also significant. A modified fast track score > 10 failed to predict recovery of muscle power in most patients. TRIAL REGISTRATION German Clinical Trial Register DRKS-ID DRKS00006032 ; Registered: 2014/04/03.
