succinylcholine vs rocuronium

The authors of this paper suggest that succinylcholine has a faster onset of action compared to rocuronium, however, Curley et al in Crit Care Med 2011 suggested that at a dose of ≥1.2 mg/kg IV, rocuronium has been shown to have a mean onset time of 55seconds, which is similar to the mean onset time of succinylcholine (50 seconds). So far, succinylcholine and rocuronium have not been compared in an adequately powered randomized trial in intensive care. We have found that rocuronium is slightly less effective than succinylcholine for creating excellent and acceptable intubation conditions. JAMA December 2019. Majority of older trials used low doses of rocuronium (0.6-.8mg/kg) which we now know to be sub-optimal. succinylcholine and rocuronium exhibited no differences in ﬁrst-pass success (87.0% versus 87.5%) or adverse events (14.7% versus 14.8%). A high incidence of detection bias amongst the trials coupled with significant heterogeneity means . They cause profound muscle relaxation or paralysis. However, these blocking agents have a delayed onset and a prolonged duration of action when used in the standard doses [5]. Please post any discussion to the emupdates reddit page. Previous: Succinylcholine vs. Rocuronium: Battle of the RSI . Current evidence suggests that succinylcholine provides superior intubation conditions to rocuronium . 2, Table 2). Non-depolarizing drugs have the advantage of causing less pain due to post-paralysis myalgias. Over the years, propofol has replaced thiopental as the most commonly used intravenous hypnotic, and rocuronium has been shown to be useful during RSI as it has a short onset time that may be reduced even further when the dose is increased to 0.6-0.7 mg/kg, but the duration of action of rocur onium is much longer than that of succinylcholine, especially when given in high doses. The number of patients with successful first-attempt intubation was 455 of 610 (74.6%) in the rocuronium group vs 489 of 616 (79.4%) in the succinylcholine group, with a between-group difference . For years, Succinylcholine was hailed as the go-to paralytic in an RSI, but is it really the best choice? School of Medicine Izmir Turkey Citation: O. Karcioglu : Dilemma In Rapid Sequence Intubation: Succinylcholine Vs. Rocuronium . It's from 2013 but still very much on point, illustrating just how little progress we've made with this issue: Moreover, the mean dose of succinylcholine was 1.8 mg/kg, whereas the mean dose of rocuronium was 1.2 mg/kg. For 8 minute Pecha Kucha competition at Scott Weingart's ED Critical Care Conference, January 13 2010. Generally, succinylcholine is best used for situations where rapid blocking is needed, such as for rapid sequence intubation. 2003 Volume 7 Number 1 I found a Cochrane review comparing succinylcholine vs rocuronium (a non-depolarizing agent) and while rocuronium has fewer side effects, succinylcholine was still found to be preferable. Screencast: Rocuronium vs. Succinylcholine in 8 minutes. The lowest oxygen saturation was 87 2% in the FIGURE 3: Duration of Clinical Effect vs. Concerns relate to the side effects of succinylcholine and to slower onset and inferior intubation conditions associated with rocuronium. Comparison of rocuronium and suxamethonium for use during rapid sequence induction of anaesthesia. Non-depolarizing drugs have the advantage of causing less pain due to post-paralysis myalgias. 2008 Apr 16;(2):CD002788. saline (saline group, n = 20), patients were anaesthetized with a 2.0 mg/kg of i.v. Rocuronium 10mg/ml. Intubation attempts. The controversy of succinylcholine vs rocuronium for ED RSI has been ongoing for years. Patients were intubated using direct laryngoscopy and clinicians used stylets in fewer than 10% of intubations. It was found that succinylcholine performed better overall than rocuronium with respect to both the primary outcome, excellent intubating conditions (NNH of 8), and the secondary outcome, adequate (excellent or good) intubating conditions (NNH of 22). Overall, succinylcholine was superior to rocuronium for achieving excellent intubating conditions (risk ratio (95%CI) 0.86 (0.81 to 0.92), n = 4151) and clinically acceptable intubation conditions (risk ratio (95%CI) 0.97 (0.95-0.99), n = 3992). These data suggest that there is a large (10-fold) difference between the rate for atracurium and the rates for succinylcholine and rocuronium (P < 0.001). succinylcholine vs. rocuronium & rare catastrophic complications . This is used primarily for intubation at the beginning of surgery. Secondary Outcome: Sedatives used. All patients received etomidate as the induction sedative and were successfully intubated. after succinylcholine vs. 329 (303-356)s after rocuro-nium (P50.01) (Fig. The onset of roc is pretty close, 30-60 seconds, just a tick slower than sux. succinylcholine. So far, succinylcholine and rocuronium have not been compared in an adequately powered randomized trial in intensive care. of Emergency Medicine Dokuz Eylul Univ. Just like ketamine in the section above, the dosing of rocuronium in comparison studies vs. succinylcholine was not what was recommended for ED practice. A clinical trial is needed to conﬁrm these observations. Succinylcholine ≥ 1.5 mg/kg. Rocuronium has a rapid onset of action and a moderate duration of action and can be used in rapid sequence induction [6]. The rate of first-attempt intubation success was similar between the succinylcholine and rocuronium groups (72.6% vs. 72.9%, p=0.95). Cochrane Database Syst Rev. The Internet Journal of Emergency and Intensive Care Medicine. This analysis showed no difference in first-pass success (87.0% versus 87.5%) or adverse events (14.7% versus 14.8%) between succinylcholine and rocuronium groups. Currently, Rocuronium costs about $40 for a 100mg vial and is shelf stable for about 12 weeks, while Succinylcholine is about the same for a 200mg vial. 2009 Aug;37(2):183-8. Introduction. Succinylcholine is rapidly metabolized by plasma pseudocholinesterase and does not need a reversal agent.9Rocuronium has a longer duration of action. This is advantageous during surgery since muscle paralysis can aid in placement of the breathing tube. After i.v. LIMITATIONS. Screencast: Rocuronium vs. Succinylcholine in 8 minutes. The dose of roc for RSI is roughly .6-1.2mg/kg so your kits should have at least 100mg in them. How this is relevant to clinical practice Perceived intubating differences between succinylcholine and rocuronium may not be clinically important. This was a multicenter noninferiority trial in which 1,248 adults undergoing prehospital RSI in France were randomized to either succinylcholine or rocuronium. Rocuronium appears to be an acceptable Or we could calculate backwards and say how many mg/kg of vecuronium would give you the same number . Of these, 113 and 214 intubations were performed using succinylcholine and rocuronium, respectively. Succinylcholine and rocuronium are widely used to facilitate rapid sequence induction (RSI) intubation in intensive care. Table 1. The Cochrane review also found in general that succinylcholine is faster although high dose roc is pretty close. One is a depolarizing agent "Sux". Rocuronium versus succinylcholine for rapid sequence induction of anesthesia and endotracheal intubation: a prospective, randomized trial in emergent cases. ObjectiveThe present study aimed to evaluate the impact of 1.5 mg/kg succinylcholine or 1.2 mg/kg rocuronium, vs. 1.0 mg/kg succinylcholine on apnea duration in patients underwent rapid sequence induction (RSI).MethodsThis prospective cohort study was conducted in the Department of Anesthesiology in Shanghai General Hospital from July 2020 to November 2020. Rocuronium was less effective than suxamethonium at doses of .6-.7mg/kg, (2808 patients), RR 0.8 (0.72-0.88), NNTH 6 (7-5). Here is the classic Rubin Strayer video on Rocuronium versus Succinylcholine. Overall, succinylcholine was superior to rocuronium for achieving excellent intubating conditions (risk ratio (95%CI) 0.86 (0.81 to 0.92), n = 4151) and clinically acceptable intubation conditions (risk ratio (95%CI) 0.97 (0.95-0.99), n = 3992). Non-depolarizing drugs have the advantage of causing less pain due to post-paralysis myalgias. JEMS - Succinylcholine VS Rocuronium, which is the best paralytic?For years Succinylcholine was hailed as the go to paralytic in an RSI, but is it really th. There was no statistically significant difference between either drug at doses of .9-1.2mg/kg. Methods: Sixty patients with a body mass index (BMI) between 25 and 30 kg/m 2, American Society of Anesthesiologists class I or II, undergoing general anesthesia were randomly divided into a succinylcholine group and a rocuronium group. JAMA. Concerns relate to the side effects of succinylcholine and to slower onset and inferior intubation conditions associated with rocuronium. Rocuronium should therefore only be used as an alternative to succinylcholine when it is known that succinylcholine should not be used and a more prolonged intubation is expected. The incidence of adverse events was also comparable between the two paralytic agents, with a rate of 14.7% for succinylcholine and 14.8% for rocuronium (adjusted OR 1.1; 95% confidence interval of 0.9 to 1.3). A Randomized Clinical Trial. Unsurprisingly, individual 2 × 2 comparisons reveal that the differences reside in the rates of anaphylaxis to succinylcholine and rocuronium compared with the other agents. Unsurprisingly, individual 2 × 2 comparisons reveal that the differences reside in the rates of anaphylaxis to succinylcholine and rocuronium compared with the other agents. When succinylcholine was used as the neuromuscular blocking drug for rapid sequence induction of anesthesia, the median intubation sequence was 35 s shorter than when rocuronium was used. Succinylcholine (also known as suxamethonium and abbreviated as SCh) was first synthesized in 1906 and clinically introduced in the early 1950's after its neuromuscular blocking properties were discovered in 1949. . Neuromuscular blockers are a class of drug used on unconscious patients in hospitals and most often in operating rooms. While the absolute difference in first-pass success was 4.8%, the confidence interval extended to 9%, which exceeds the . This opens in a new window. Without reversal, an RSI intubating dose (1.2 mg/kg) would result in extended paralysis.10The reversal agent sugammadex, specific for rocuronium and vecuronium, can provide rapid recovery of With rising popularity of rocuronium, this publication is a timely addition to debate regarding the ultimate paralytic in RSI. Neostigmine, pyridostigmine, and edrophonium are usually coadministered with anticholinergics, such as atropine or glycopyrrolate, to counter muscarinic effects like bradycardia, nausea, and bronchospasm. Succinylcholine and rocuronium are widely used to facilitate rapid sequence induction (RSI) intubation in intensive care. Time to recovery of 25% of train -of -four was significantly longer for patients receiving rocuronium, 46.3 +23.4 compared to 5.8 +3.3 minutes for succinylcholine. It also remains a major drug in rapid sequence induction and intubation in many countries (1-3).Nevertheless, the British Guidelines for the management of tracheal intubation in critical ill adults recommend rocuronium as the first-line muscle relaxant for endotracheal intubation in . Both succinylcholine and vecuronium are muscle relaxing drugs used during surgery. Non-depolarizing drugs have the advantage of causing less pain due to post-paralysis myalgias. Contraindications to succinylcholine include allergy, history of malignant hyperthermia, denervation syndromes, and patients who are 24-48 h post burn or crush injury. Succinylcholine 1mg /kg IV has a faster onset of action than rocuronium 0.6 mg/kg IV, however this advantage disappears when a larger dose of 1.2 mg/kg rocuronium is used. Apnea duration was defined as the . We report here the anesthetic management of a patient with schizophrenia and pseudocholinesterase deficiency. 1, 2 Studies comparing these agents for RSI have primarily evaluated their effect on intubation conditions, which may vary in a dose-dependent manner. Compared to succinylcholine, rocuronium is associated with less optimal intubation conditions [ 3, 9] and a longer intubation sequence [ 9] in the operating theatre. It also is shorter acting, so that if intubation is unsuccessful, the patient is not paralyzed for as long. Overall, succinylcholine was superior to rocuronium for achieving excellent intubating conditions (risk ratio (95%CI) 0.86 (0.81 to 0.92), n = 4151) and clinically acceptable intubation conditions (risk ratio (95%CI) 0.97 (0.95-0.99), n = 3992). Non-depolarizing drugs have the advantage of causing less pain due to post-paralysis myalgias. They make surgery significantly easier for the surgeon, since tense . When ventilation with 100% O 2 was started, there was a further decline in oxygen saturation. Sugammadex: a selective relaxant binding agent and rapid-acting antidote for rocuronium and vecuronium. This opens in a new window. We have found that rocuronium is slightly less effective than succinylcholine for creating excellent and acceptable intubation conditions. Children - Why Body Language Is Brand Positioning Strategy -Walmart, An Example ¦ by Shah Succinylcholine vs. Rocuronium: Battle of the RSI Ries ¦ Positioning Pioneers ¦ ConsultingHow to Create a Marketing Strategy in 5 Steps (with Examples) Table 1 shows that the cases in both groups were comparable on the basis of mean age in years and SD. The use of Rocuronium Bromide Injection before succinylcholine, for the purpose of attenuating some of the side effects of succinylcholine, has not been studied. Succinylcholine has been shown in some studies to produce better intubating conditions more quickly. It also remains a major drug in rapid sequence induction and intubation in many countries (1-3).Nevertheless, the British Guidelines for the management of tracheal intubation in critical ill adults recommend rocuronium as the first-line muscle relaxant for endotracheal intubation in . Succinylcholine chloride is an agent commonly used to facilitate endotracheal intubation. In fact if we look at a 1mg/kg dose of the following drugs in a typical 100 kg individual we will find they include the following number of molecules. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Succinylcholine $40/200mg vial, but only shelf stable for 2 weeks. Read more about it here!. The mean recovery period was 43 (39-48)s in succinylcholine vs. 36 (33-38)s in rocuronium (P50.002). Primary outcome: Time to initiation of continuous sedation or analgesia after RSI. Rocuronium should therefore only be used as an alternative to succinylcholine when it is known that succinylcholine should not be used and a more prolonged intubation is expected. Cost: rocuronium $40/100mg vial- shelf stable for 12 weeks. Noninferiority randomized clinical trial. These data suggest that there is a large (10-fold) difference between the rate for atracurium and the rates for succinylcholine and rocuronium (P < 0.001). Because the CI lines go above the prespecified noninferiority margin of 7%, the null hypothesis that succinylcholine is superior cannot be rejected. propofol . Rocuronium is a useful alternative when succinylcholine is contraindicated. After a 3-min preoxygenation, patients received rapid sequence induction of general anesthesia with midazolum . Contraindications to succinylcholine include allergy, history of malignant hyperthermia, denervation syndromes, and patients who are 24-48 h post burn or crush injury. Epub 2008 Dec 20. Review. First-pass success occurred in 74.6% of patients who received rocuronium and 79.4% who received succinylcholine. Baseline Patient Data in a Study of the Effect of Rocuronium vs Succinylcholine on Out-of-Hospital Endotracheal Intubation Success View LargeDownload Table 2. Anesth Analg 2005; 101:1356 - 61. Some clinicians advocate for one medication over the other as they have distinct properties: Succinylcholine has a faster onset and wears off more quickly; rocuronium has fewer contraindications. Vecuronium 1.56 x 10 -4 moles. Pancuronium 1.36 x 10 -4 moles. succinylcholine) or in the number of patients receiving excellent intubati ng scores. Conclusions:Both rocuronium and succinylcholine are effective and potent muscle paralytic agents. There was no statistically significant difference between either drug at doses of .9-1.2mg/kg. For 8 minute Pecha Kucha competition at Scott Weingart's ED Critical Care Conference, January 13 2010. April 2018. Bottom Line: The best available data shows an association between the use of succinylcholine and mortality in patients with severe TBI requiring RSI. In a prospective, randomized study, 180 patients underwent induction with propofol (1.5 mg/kg) plus fentanyl (2.0 μg/kg). • Succinylcholine is associated with adverse events: hyperkalemia and increased O2 consumption • No randomized trial has compared these two NMBA in emergency settings Objective • Compared rocuronium vs. succinylcholine use in emergency out-of-hospital intubation situations. Group I received Succinylcholine 2mg/kg body weight as Inj. Contraindications to succinylcholine include allergy, history of malignant hyperthermia, denervation syndromes, and patients who are 24-48 h post burn or crush injury. . Rocuronium has emerged as the muscle relaxant of choice in only in cases where Succinylcholine is contraindicated. Contraindications to succinylcholine include allergy, history of malignant hyperthermia, denervation syndromes, and patients who are 24-48 h post burn or crush injury. Those papers show that high dose rocuronium has a "similar" onset time although if you look at the raw numbers sux is still quite a bit faster (34 versus 54 sec at the laryngeal adductors, 56 versus 65 sec at the adductor pollicis). Introduction. tracurium, may be alternative agents to succinylcholine. The authors of this paper suggest that succinylcholine has a faster onset of action compared to rocuronium, however, Curley et al in Crit Care Med 2011 suggested that at a dose of ≥1.2 mg/kg IV, rocuronium has been shown to have a mean onset time of 55seconds, which is similar to the mean onset time of succinylcholine (50 seconds). These authors postulated that intubating conditions might be reached much earlier with succinylcholine than with rocuronium, thus making succinylcholine preferable for emergency rapid-sequence intubation (RSI). PMID: 19097730. Quality of evidence Electroconvulsive therapy was performed using succinylcholine and rocuronium as the neuromuscular blocking agents in the first seven and latter six treatments, respectively, and Rocuronium and sugammadex appear to be useful in situations in which succinylCholine is contraindicated. Vecuronium is a non-depolarizing agent "Vec" used for the remainder of the case when long term muscle relaxation is required. Rocuronium 1.64 x 10 -4 moles. pretreatment with either remifentanil 1.5 µg/kg (remifentanil group, n = 20) or an equivalent volume of i.v. Unfortunately, the larger dose comes with a longer duration of action, which may be clinically undesirable. A Comparison of the Intubation Conditions between Mivacurium and Rocuronium during Balanced Anesthesia Anesthesiology (March 1998) Reversal of Profound Neuromuscular Block by Sugammadex Administered Three Minutes after Rocuronium: A Comparison with Spontaneous Recovery from Succinylcholine Rocuronium is a useful alternative when succinylcholine is contraindicated. Perry JJ, Lee JS, Sillberg VA, Wells GA. Rocuronium versus succinylcholine for rapid sequence induction intubation. However, succinylcholine has a shelf life of. Rocuronium is a useful alternative when succinylcholine is contraindicated. Intubation: Succinylcholine Vs. Rocuronium Ozgur Karcioglu MD Emergency Physician Dept. Onset time: Same duration of 45-60 seconds when the higher end dose of rocuronium is used (1.2 mg/kg) Rocuronium has a limited side effect profile, mostly hepatoxicity, compared to long side effect profile of . It is known that pretreatment with IV magnesium sulfate shortens . LIMITATIONS Majority of older trials used low doses of rocuronium (0.6-.8mg/kg) which we now know to be sub-optimal. Please post any discussion to the emupdates reddit page. Succinylcholine 50mg/ml respectively and those in Group II received Rocuronium .6mg/kg body weight as Inj. The primary outcome, first-pass success rate, was 74.6% for rocuronium versus 79.4% for succinylcholine (1-sided 97.5% CI, -9% to ∞), with the confidence interval exceeding the . Table 1: Age distribution among cases of both groups. I've seen vecuronium a few times on TV too, but strangely enough, rocuronium doesn't seem to get much airtime, even though in . Rocuronium is at least equivalent in terms of outcomes but may be superior.
