Should rocuronium and sugammadex replace succinylcholine for airway emergencies in class B ambulatory anesthesia settings?

INTRODUCTION: In class B surgical facilities, where only oral or intravenous (IV) sedation is employed without the administration of volatile anesthetics, laryngospasm is among the most common airway complications. However, these facilities generally do not stock succinylcholine to avoid the cost of storing dantrolene for the treatment of malignant hyperthermia (MH). High dose IV rocuronium with sugammadex reversal has been suggested as an alternative to succinylcholine for airway emergencies. The aim of this paper was to evaluate the clinical utility, patient safety, and financial implications of replacing succinylcholine with rocuronium and sugammadex in lieu of stocking dantrolene in class B facilities. EVIDENCE ACQUISITION: A systematic review of the literature concerning neuromuscular blockade for airway emergencies in class B settings in adult patients was conducted. The MEDLINE and EMBASE databases were searched for published studies from January 1, 1990, to October 1, 2021. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system was used to assess the certainty of evidence. EVIDENCE SYNTHESIS: The search strategy yielded 1124 articles. After review, 107 articles were included, with 49 graded as "strong" evidence to provide recommendations for the posed questions. CONCLUSIONS: The use of succinylcholine in isolation without volatile agents has a low incidence of triggering MH. Laryngospasm is a common airway emergency that requires immediate treatment to avoid morbidity and mortality. Both succinylcholine and rocuronium-sugammadex provide adequate treatment of airway emergencies and rapid return of spontaneous ventilation, but succinylcholine has a superior economic and clinical profile.

Acupuncture for alcohol use disorder.

Alcohol use disorder (AUD) is a common medical and social problem, affecting about 240 million people in the world. To address this major health concern, the currently available treatments for AUD need to be improved. Acupuncture, a popular form of complementary and alternative therapy, is emerging as an effective treatment for AUD. This review summarizes how preclinical and clinical studies are related to the application of acupuncture for AUD. These studies suggest that if used correctly, acupuncture may effectively reduce alcohol intake, attenuate alcohol withdrawal syndrome, and rebalance AUD-induced maladaptation in neurotransmitters and hormones in related brain areas. The progress of research in this field is at an early stage. Future investigations with rigorous design and carefully constructed protocols are still needed.

Intraoperative Low-frequency Electroacupuncture under General Anesthesia Improves Postoperative Recovery in a Randomized Trial.

Neuronal stimulation improves physiological responses to infection and trauma, but the clinical potential of this strategy is unknown. We hypothesized that transdermal neural stimulation through low-frequency electroacupuncture might control the immune responses to surgical trauma and expedite the postoperative recovery. However, the efficiency of electroacupuncture is questioned due to the placebo effect. Here, electroacupuncture was performed on anesthetized patients to avoid any placebo. This is a prospective double-blinded pilot trial to determine whether intraoperative electroacupuncture on anesthetized patients improves postoperative recovery. Patients with electroacupuncture required 60% less postoperative analgesic, even they had pain scores similar to those in the control patients. Electroacupuncture prevented postoperative hyperglycemia and attenuated serum adrenocorticotropic hormone in the older and heavier group of patients. From an immunological perspective, electroacupuncture did not affect the protective immune responses to surgical trauma, including the induction of interleukin-6 and interleukin-10. The most significant immunological effect of electroacupuncture was enhancing transforming growth factor-ß1 production during surgery in the older and lighter group of patients. These results suggest that intraoperative electroacupuncture on anesthetized patients can reduce postoperative use of analgesics and improve immune and stress responses to surgery.
