Meta-Analysis Review
BACKGROUND
Acetylcholinesterase inhibitors, such as neostigmine, have traditionally been used for reversal of non-depolarizing neuromuscular blocking agents. However, these drugs have significant limitations, such as indirect mechanisms of reversal, limited and unpredictable efficacy, and undesirable autonomic responses. Sugammadex is a selective relaxant-binding agent specifically developed for rapid reversal of non-depolarizing neuromuscular blockade induced by rocuronium. Its potential clinical benefits include fast and predictable reversal of any degree of block, increased patient safety, reduced incidence of residual block on recovery, and more efficient use of healthcare resources.
OBJECTIVES
The main objective of this review was to compare the efficacy and safety of sugammadex versus neostigmine in reversing neuromuscular blockade caused by non-depolarizing neuromuscular agents in adults.
SEARCH METHODS
We searched the following databases on 2 May 2016: Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE (WebSPIRS Ovid SP), Embase (WebSPIRS Ovid SP), and the clinical trials registries www.controlled-trials.com, clinicaltrials.gov, and www.centerwatch.com. We re-ran the search on 10 May 2017.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) irrespective of publication status, date of publication, blinding status, outcomes published, or language. We included adults, classified as American Society of Anesthesiologists (ASA) I to IV, who received non-depolarizing neuromuscular blocking agents for an elective in-patient or day-case surgical procedure. We included all trials comparing sugammadex versus neostigmine that reported recovery times or adverse events. We included any dose of sugammadex and neostigmine and any time point of study drug administration.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened titles and abstracts to identify trials for eligibility, examined articles for eligibility, abstracted data, assessed the articles, and excluded obviously irrelevant reports. We resolved disagreements by discussion between review authors and further disagreements through consultation with the last review author. We assessed risk of bias in 10 methodological domains using the Cochrane risk of bias tool and examined risk of random error through trial sequential analysis. We used the principles of the GRADE approach to prepare an overall assessment of the quality of evidence. For our primary outcomes (recovery times to train-of-four ratio (TOFR) > 0.9), we presented data as mean differences (MDs) with 95 % confidence intervals (CIs), and for our secondary outcomes (risk of adverse events and risk of serious adverse events), we calculated risk ratios (RRs) with CIs.
MAIN RESULTS
We included 41 studies (4206 participants) in this updated review, 38 of which were new studies. Twelve trials were eligible for meta-analysis of primary outcomes (n = 949), 28 trials were eligible for meta-analysis of secondary outcomes (n = 2298), and 10 trials (n = 1647) were ineligible for meta-analysis.We compared sugammadex 2 mg/kg and neostigmine 0.05 mg/kg for reversal of rocuronium-induced moderate neuromuscular blockade (NMB). Sugammadex 2 mg/kg was 10.22 minutes (6.6 times) faster then neostigmine 0.05 mg/kg (1.96 vs 12.87 minutes) in reversing NMB from the second twitch (T2) to TOFR > 0.9 (MD 10.22 minutes, 95% CI 8.48 to 11.96; I = 84%; 10 studies, n = 835; GRADE: moderate quality).We compared sugammadex 4 mg/kg and neostigmine 0.07 mg/kg for reversal of rocuronium-induced deep NMB. Sugammadex 4 mg/kg was 45.78 minutes (16.8 times) faster then neostigmine 0.07 mg/kg (2.9 vs 48.8 minutes) in reversing NMB from post-tetanic count (PTC) 1 to 5 to TOFR > 0.9 (MD 45.78 minutes, 95% CI 39.41 to 52.15; I = 0%; two studies, n = 114; GRADE: low quality).For our secondary outcomes, we compared sugammadex, any dose, and neostigmine, any dose, looking at risk of adverse and serious adverse events. We found significantly fewer composite adverse events in the sugammadex group compared with the neostigmine group (RR 0.60, 95% CI 0.49 to 0.74; I = 40%; 28 studies, n = 2298; GRADE: moderate quality). Risk of adverse events was 28% in the neostigmine group and 16% in the sugammadex group, resulting in a number needed to treat for an additional beneficial outcome (NNTB) of 8. When looking at specific adverse events, we noted significantly less risk of bradycardia (RR 0.16, 95% CI 0.07 to 0.34; I= 0%; 11 studies, n = 1218; NNTB 14; GRADE: moderate quality), postoperative nausea and vomiting (PONV) (RR 0.52, 95% CI 0.28 to 0.97; I = 0%; six studies, n = 389; NNTB 16; GRADE: low quality) and overall signs of postoperative residual paralysis (RR 0.40, 95% CI 0.28 to 0.57; I = 0%; 15 studies, n = 1474; NNTB 13; GRADE: moderate quality) in the sugammadex group when compared with the neostigmine group. Finally, we found no significant differences between sugammadex and neostigmine regarding risk of serious adverse events (RR 0.54, 95% CI 0.13 to 2.25; I= 0%; 10 studies, n = 959; GRADE: low quality).Application of trial sequential analysis (TSA) indicates superiority of sugammadex for outcomes such as recovery time from T2 to TOFR > 0.9, adverse events, and overall signs of postoperative residual paralysis.
AUTHORS' CONCLUSIONS
Review results suggest that in comparison with neostigmine, sugammadex can more rapidly reverse rocuronium-induced neuromuscular block regardless of the depth of the block. Sugammadex 2 mg/kg is 10.22 minutes (˜ 6.6 times) faster in reversing moderate neuromuscular blockade (T2) than neostigmine 0.05 mg/kg (GRADE: moderate quality), and sugammadex 4 mg/kg is 45.78 minutes (˜ 16.8 times) faster in reversing deep neuromuscular blockade (PTC 1 to 5) than neostigmine 0.07 mg/kg (GRADE: low quality). With an NNTB of 8 to avoid an adverse event, sugammadex appears to have a better safety profile than neostigmine. Patients receiving sugammadex had 40% fewer adverse events compared with those given neostigmine. Specifically, risks of bradycardia (RR 0.16, NNTB 14; GRADE: moderate quality), PONV (RR 0.52, NNTB 16; GRADE: low quality), and overall signs of postoperative residual paralysis (RR 0.40, NNTB 13; GRADE: moderate quality) were reduced. Both sugammadex and neostigmine were associated with serious adverse events in less than 1% of patients, and data showed no differences in risk of serious adverse events between groups (RR 0.54; GRADE: low quality).

Review
Perioperative anaphylaxis is a life-threatening clinical condition that is typically the result of drugs or substances used for anesthesia or surgery. The most common cause of anaphylaxis during anesthesia is reportedly neuromuscular blocking agents. Of the many muscle relaxants that are clinically available, rocuronium is becoming popular in many countries. Recent studies have demonstrated that succinylcholine (but also rocuronium use) is associated with a relatively high rate of IgE-mediated anaphylaxis compared with other muscle relaxant agents. Sugammadex is widely used for reversal of the effects of steroidal neuromuscular blocking agents, such as rocuronium and vecuronium. Confirmed cases of allergic reactions to clinical doses of sugammadex have also been recently reported. Given these circumstances, the number of cases of hypersensitivity to either sugammadex or rocuronium is likely to increase. Thus, anesthesiologists should be familiar with the epidemiology, mechanisms, and clinical presentations of anaphylaxis induced by these drugs. In this review, we focus on the diagnosis and treatment of anaphylaxis to sugammadex and neuromuscular blocking agents. Moreover, we discuss recent studies in this field, including the diagnostic utility of flow cytometry and improvement of rocuronium-induced anaphylaxis with the use of sugammadex.

Vecuronium bromide (Piperidinium, 1-[(2β,3α,5α,16β,17β)-3,17-bis(acetyloxy)-2-(1-piperidinyl)androstan-16-yl]-1-methyl-, bromide; Norcuron®) has been extensively used in anesthesiology practice as neuromuscular blocking agent since its launch on the market in 1982. However, a detailed crystallographic and NMR analysis of its advanced synthetic intermediates is still lacking. Hence, with the aim of filling this literature gap, vecuronium bromide was prepared starting from the commercially available 3β-hydroxy-5α-androstan-17-one (epiandrosterone), implementing some modifications to a traditional synthetic procedure. A careful NMR study allowed the complete assignment of the H, C, and N NMR signals of vecuronium bromide and its synthetic intermediates. The structural and stereochemical characterization of 2β,16β-bispiperidino-5α-androstane-3α,17β-diol, the first advanced synthetic intermediate carrying all the stereocenters in the final configuration, was described by means of single-crystal X-ray diffraction and Hirshfeld surface analysis, allowing a detailed conformational investigation.

This study employed Fourier Transform near-infrared spectrometry to assess the quality of vecuronium bromide, a neuromuscular blocking agent. Spectral data from two lots of vecuronium were collected and analyzed using the BEST metric, principal component analysis (PCA) and other statistical techniques. The results showed that there was variability between the two lots and within each lot. Several outliers in the spectral data suggested potential differences in the chemical composition or sample condition of the vials. The outliers were identified and their spectral features were examined. A total of eight unique outliers were found in the PC space from PCs 1 to 9, so 22% of the total vials were outliers. The study findings suggest that the manufacturing process of vecuronium bromide may have been operating outside of a state of process control. Further investigation is needed to determine the source of these variations and their impact on the safety and efficacy of the drug product.

Anesthesia, Essays and Researches 2016The present study is undertaken to compare the hemodynamic effects using vecuronium versus rocuronium for maintenance in patients undergoing general surgical procedures.
AIMS
The present study is undertaken to compare the hemodynamic effects using vecuronium versus rocuronium for maintenance in patients undergoing general surgical procedures.
SETTINGS AND DESIGN
It is a prospective, randomized, and cohort study.
SUBJECTS AND METHODS
100 patients were randomly divided into two groups. All patients were induced with 5 mg/kg of thiopentone sodium, and intubation conditions were achieved with 1.5 mg/kg of suxamethonium, using a well-lubricated cuffed endotracheal tube of appropriate size. When the patient started to breathe spontaneously, they were administered either 0.6 mg/kg of rocuronium (Group A) or 0.1 mg/kg of vecuronium (Group B). Hemodynamic parameters (heart rate and mean arterial pressure [MAP]) were monitored before administering the drug; at 1, 5, 10, 15, and 20 min after the drug and at the end of the surgery.
STATISTICAL ANALYSIS USED
Data were compiled, analyzed and presented as frequency, proportions, mean, standard deviation, percentages, and t-test using SPSS (version 16). A P < 0.05 was considered as significant.
RESULTS
The heart rate increased significantly at 1-min and 5-min after administration of rocuronium (83.76 ± 10.37 and 86.8 ± 9.98), unlike vecuronium. However, it gradually declined towards normal, and change in heart rate with either drug was not significant beyond 10 min. The MAP decreased significantly at 1-min after administration of rocuronium (96.68 ± 7.57) which later showed a gradual increasing trend when compared to vecuronium which had no statistically significant change at any time.
CONCLUSIONS
For short surgical procedures rocuronium is a good alternative to vecuronium, as the drug is reasonably cardio stable, produces excellent intubation conditions, has a shorter duration of action, and shows minimal cumulative effect.

OBJECTIVES
We observed that patients treated with continuous vecuronium or esmolol infusions showed elevated plasma sodium measurements when measured by the routine chemistry analyzer as part of the basic metabolic panel (Vitros 5600; Ortho Clinical Diagnostics, Raritan, NJ), but not by blood gas analyzers (RAPIDLab 1265; Siemens, Tarrytown, NY). Both instruments use direct ion-selective electrode technology, albeit with different sodium ionophores (basic metabolic panel: methyl monensin, blood gas: glass). We questioned if the basic metabolic panel hypernatremia represents artefactual pseudohypernatremia.
DESIGN
We added vecuronium bromide or esmolol hydrochloric acid to pooled plasma samples and compared sodium values measured by both methodologies. We queried sodium results from the electronic medical records of patients admitted at Children's Hospital of Philadelphia from 2016 to 2018 and received vecuronium and/or esmolol infusion treatment during their admissions.
SETTING
PICU of a quaternary, free-standing children's hospital.
PATIENTS
Children admitted to the hospital who received vecuronium and/or esmolol infusion.
MEASUREMENTS AND MAIN RESULTS
Sodium was measured in pooled plasma samples by basic metabolic panel and blood gas methodologies after adding vecuronium bromide or esmolol hydrochloric acid, leading to a dose-response increase in basic metabolic panel sodium measurements. A repeated measures regression analysis of our electronic medical records showed that the vecuronium dose predicted the Δ sodium (basic metabolic panel-blood gas) sodium within 12 hours of the vecuronium administration ( < 0.0018). Esmolol showed a similar trend ( = 0.13). This occurred primarily in central line samples with continuous vecuronium or esmolol infusions.
CONCLUSIONS
Vecuronium and esmolol can falsely elevate direct ion-selective electrode sodium measurements on Vitros chemistry analyzers. Unexpectedly high sodium measurements in patients receiving vecuronium and/or esmolol infusions should be further investigated with an alternate sample type (i.e., peripheral blood) or measurement methodology (i.e., blood gas) to guide treatment decisions.

BACKGROUND
The clinical actions of sugammadex have been well studied, but the detailed molecular mechanism of the drug encapsulation process has not been systematically documented. The hypothesis was that sugammadex would attract rocuronium and vecuronium via interaction with the sugammadex side-chain "tentacles," as previously suggested.
METHODS
Computational molecular dynamics simulations were done to investigate docking of sugammadex with rocuronium and vecuronium. To validate these methods, strength of binding was assessed between sugammadex and a heterogeneous group of nine other drugs, the binding affinities of which have been experimentally determined. These observations hinted that high concentrations of unbound sugammadex could bind to propofol, potentially altering its pharmacokinetic profile. This was tested experimentally in in vitro cortical slices.
RESULTS
Sugammadex encapsulation of rocuronium involved a sequential progression down a series of metastable states. After initially binding beside the sugammadex molecule (mean ± SD center-of-mass distance = 1.17 ± 0.13 nm), rocuronium then moved to the opposite side to that hypothesized, where it optimally aligned with the 16 hydroxyl groups (distance, 0.82 ± 0.04 nm) before entering the sugammadex cavity to achieve energetically stable encapsulation by approximately 120 ns (distance, 0.35 ± 0.12 nm). Vecuronium formed fewer hydrogen bonds with sugammadex than did rocuronium; hence, it was less avidly bound. For the other molecules, the computational results showed good agreement with the available experimental data, showing a clear bilogarithmic relation between the relative binding free energy and the association constant (R2 = 0.98). Weaker binding was manifest by periodic unbinding. The brain slice results confirmed the presence of a weak propofol-sugammadex interaction.
CONCLUSIONS
Computational simulations demonstrate the dynamics of neuromuscular blocking drug encapsulation by sugammadex occurring from the opposite direction to that hypothesized and also how high concentrations of unbound sugammadex can potentially weakly bind to other drugs given during general anesthesia.
