Recent literature suggests that the use of sugammadex for the reversal of neuromuscular blocking agents (NMBAs) reduces the risk of postoperative myasthenic crisis (MC) in patients with myasthenia gravis (MG), particularly after thymectomy, but studies are lacking on emergency surgeries. We achieved successful intraoperative reversal of neuromuscular blockade (NMB) using a combination of sugammadex and neostigmine (with glycopyrrolate). However, MC was not avoided and reintubation was required on postoperative day 1.A 65-year-old male with a longstanding history of MG presented to the emergency department with complaints of abdominal pain, diarrhea, vomiting, chills, and fatigue for three days. A computed tomography (CT) scan of the abdomen showed acute appendicitis, for which he underwent a laparoscopic appendectomy on hospital day 1. The patient received successful general anesthesia with a rapid sequence induction using a smaller than average dose of rocuronium, given his history of MG. At the conclusion of the case, sugammadex followed by neostigmine/glycopyrrolate and a subsequent dose of sugammadex were given, with reversal of NMB. The patient was successfully extubated but required reintubation on postoperative day 1 for hypercapnic respiratory failure.Our case report on this patient with MG yields two topics that have not been extensively examined. First, dual therapy with sugammadex and neostigmine/glycopyrrolate may provide significant clinical benefit over individual therapy for NMBA reversal, given that their mechanisms of action are different and particularly when sugammadex is given prior to neostigmine/glycopyrrolate. Second, anesthesia literature is lacking on MG patients undergoing emergency surgeries. While sugammadex has been promising in medically optimized non-emergent surgeries, we discuss here a case where sugammadex failed to prevent MC in the emergency surgery setting and a look into what may provide patients with the best chance for avoiding postoperative MC.
Robotic surgery has shown to have numerous benefits over traditional and laparoscopic surgery, namely, superior precision and improved recovery with shorter hospital stays. However, robotic surgery also presents several issues, including hemodynamic changes related to positioning and the use of pneumoperitoneum. These matters can be problematic in patients with neuromuscular conditions such as Friedreich ataxia (FRDA). Due to a baseline weakened musculature and a higher prevalence of cardiac disease and scoliosis, patients with FRDA may not be as likely to tolerate the cardiopulmonary physiologic changes associated with robotic surgery. Additionally, positioning for robotic surgery can be challenging in FRDA patients who have progressed to spasticity and contractures. To the best of our knowledge, there are no case reports of approaches specifically discussing anesthesia management for robotic surgery in the FRDA patient population.Anesthesia in general must be carefully planned in FRDA patients to allow for the best possible recovery and minimize complications. Due to the underlying neuromuscular compromise seen in these patients, their ability to recover from the pharmacologic and physiologic changes associated with anesthesia can be more difficult. They are prone to sensitivity to opioids, sedatives, and neuromuscular blocking agents (NMBAs) and are less likely to tolerate hemodynamic changes. Our review revealed no literature to suggest the routine use of Enhanced Recovery After Surgery (ERAS) protocols in FRDA patients or in patients with neuromuscular disease in general.The use of sugammadex has also been shown to be safe, and literature suggests superiority in both the general population and those with neuromuscular conditions. Our understanding is that there is very limited literature in regard to the safe use of sugammadex in FRDA patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
