Sugammadex induced bradycardia and hypotension: A case report and literature review

Cardiac arrest due to coronary vasospasm after sugammadex administration -a case report

BACKGROUND

Sugammadex is a widely used medication for the reversal of aminosteroid neuromuscular blockades. Although sugammadex is generally regarded to be safe, concerns about the risk of serious complications have emerged.

CASE

A 57-year-old man without a history of coronary disease was scheduled for general anesthesia to undergo cardiac radiofrequency catheter ablation due to symptomatic persistent atrial fibrillation and flutter. At the end of the procedure, he was given 400 mg of sugammadex. A little later, the electrocardiogram showed a sudden ST elevation on the inferior leads, followed by cardiac arrest. The urgent coronary angiography demonstrated total collapse of the right coronary artery. After two injections of intra-coronary nitroglycerin, the vasospasm of the right coronary artery was completely resolved. The patient recovered without sequelae and was discharged on postoperative day 5.

CONCLUSIONS

Clinicians should pay close attention to the potential risk of coronary vasospasm, even cardiac arrest, after sugammadex administration.

REVersal of nEuromusculAr bLocking Agents in Patients Undergoing General Anaesthesia (REVEAL Study)

Background: Neuromuscular blocking agent (NMBA) monitoring and reversals are key to avoiding residual curarization and improving patient outcomes. Sugammadex is a NMBA reversal with favorable pharmacological properties. There is a lack of real-world data detailing how the diffusion of sugammadex affects anesthetic monitoring and practice. Methods: We conducted an electronic health record analysis study, including all adult surgical patients undergoing general anesthesia with orotracheal intubation, from January 2016 to December 2019, to describe changes and temporal trends of NMBAs and NMBA reversals administration. Results: From an initial population of 115,046 surgeries, we included 37,882 procedures, with 24,583 (64.9%) treated with spontaneous recovery from neuromuscular block and 13,299 (35.1%) with NMBA reversals. NMBA reversals use doubled over 4 years from 25.5% to 42.5%, mainly driven by sugammadex use, which increased from 17.8% to 38.3%. Rocuronium increased from 58.6% (2016) to 94.5% (2019). Factors associated with NMBA reversal use in the multivariable analysis were severe obesity (OR 3.33 for class II and OR 11.4 for class III obesity, p-value < 0.001), and high ASA score (OR 1.47 for ASA III). Among comorbidities, OSAS, asthma, and other respiratory diseases showed the strongest association with NMBA reversal administration. Conclusions: Unrestricted availability of sugammadex led to a considerable increase in pharmacological NMBA reversal, with rocuronium use also rising. More research is needed to determine how unrestricted and safer NMBA reversal affects anesthesia intraoperative monitoring and practice.

Sugammadex for reversing neuromuscular blockages after lung surgery: A systematic review and meta-analysis

BACKGROUND

This study determined whether sugammadex was associated with a lower risk of postoperative pulmonary complications and improved outcomes in lung surgeries.

METHODS

A systematic literature search was conducted using PubMed, Embase, Web of Science, and the Cochrane Library from January 2000 to March 2022. The characteristics of lung surgeries using sugammadex treatment compared with control drugs and postoperative outcomes were retrieved. The primary outcome was estimated through a pooled odds ratio (OR) and its 95% confidence interval (CI) was identified using a random-effects model.

RESULTS

From 465 citations, 7 studies with 453 patients receiving sugammadex and 452 patients receiving a control were included. The risk of postoperative pulmonary complication (PPCs) was lower in the sugammadex group than in the control group. Also, it showed that the effect of sugammadex on PPCs in the subgroup analysis was significantly assessed on the basis of atelectasis or non-atelectasis. Furthermore, subgroup analysis based on the relationship between high body mass index (BMI) and PPCs also showed that sugammadex had less occurrence in both the high BMI (defined as BMI ≥ 25) and low BMI groups. No difference in length of hospital stay (LOS) between the two groups was observed.

CONCLUSION

This study observed that although reversing neuromuscular blockages with sugammadex in patients undergoing thoracic surgery recorded fewer PPCs and shorter extubation periods than conventional reversal agents, no difference in LOS, postanaesthesia care unit (PACU) stay length and chest tube insertion duration in both groups was observed.

Glycopyrrolate versus atropine for preventing bradycardia induced by neostigmine injection after general anesthesia surgery: a randomized open, parallel-controlled multicenter clinical trial

OBJECTIVE

With atropine as a positive control, randomized controlled clinical trials were conducted to verify the efficacy of glycopyrrolate injection in preventing bradycardia caused by neostigmine.

METHOD

Patients undergoing elective general anesthesia and non-cardiac surgery were randomly divided into an experimental group (129 cases) and control group (127 cases) (ChiCTR2100046022, http://www.chictr.org.cn/showproj.aspx?proj=126075). At the end of the operation, the test group was given glycopyrrolate 6 ug/kg + neostigmine 0.04 mg/kg, and the control group was given atropine 0.016 mg/kg + neostigmine 0.04 mg/kg, bolus time 1 min, to antagonize muscle residual effects of relaxants. We compared the area under the time curve (AUC) of the difference between heart rate and baseline heart rate within 15 minutes of administration, the measured value of heart rate per minute, and the change in heart rate compared with baseline. We verified the safety of glycopyrrolate injection through laboratory tests, clinical symptoms, signs, and adverse events/serious adverse events.

RESULTS

The AUC of the experimental group's heart rate within 15 minutes after the administration was lower than the baseline heart rate change value, (P<005). The measured value of the heart rate at each time changed less than the control group; the experimental group's heart rate remained at the baseline level for longer than the control group (P<005). There was no significant difference in the incidence of adverse reactions between the two groups of patients (P>005).

CONCLUSION

Glycopyrrolate and atropine are safe to prevent heart rate slowing induced by the non-depolarizing muscle relaxant antagonist neostigmine, and glycopyrrolate is more conducive to maintaining a stable heart rate in patients.
