Adequate recovery of residual neuromuscular blockade is required for full control of the pharynx and respiratory functions in order to prevent complications. Adequate recovery can only be obtained by neuromuscular junction monitoring with TOF ratio greater than 0.9. Often, the reversal of NMB with anticholinesterase drugs may not be completely reversed. However, in the absence of objective monitoring this diagnosis is not possible. The case illustrates the diagnosis of residual NMB even after reversal with anticholinesterase agents, resolved with the administration of sugammadex, a safe alternative to reverse the NMB induced by steroidal non-depolarizing agents.
BACKGROUND AND OBJECTIVES:The use of ultrasound imaging in peripheral nerve block has been increasing. However, there are few reports in the literature on the learning curve of the ultrasound technique. The objective of this report was to evaluate the learning curve of CET-SMA/HSL Anesthesiology residents of ultrasound-guided peripheral block using an experimental agar model.
METHODS:An experimental model was developed by filling a bowl with agar and olives. Nine residents were randomly divided in three groups (G1, G2, and G3), each one with a R1, a R2, and a R3. All three groups received theoretical explanation. G1 also had two hours of practical training, G2 had one hour, and G3 had no training. Residents were then asked to place a needle at the middle of the olive wall, near the transducer, and then reposition the needle between the olive and the bottom of the bowl, simulating the epidural injection of anesthetic. The speed and efficacy of the tasks, as well as technical flaws, were evaluated.
RESULTS:The mean length of time to perform the tasks was 37.63 seconds for G1, without technical flaws; 64.40 seconds for G2, with two technical flaws; and 93.83 seconds for G3, with 12 technical flaws.
CONCLUSIONS:This study allows us to conclude that the longer training of ultrasound-guided peripheral nerve block in an experimental model improved the learning curve of the technique.
Routine intraoperative transesophageal echocardiography in patients with congenital cardiopathy is a fundamental auxiliary method, not only for the surgeon, often having direct influence on the surgical technique used, but also for the anesthesiologist, who can get useful information for the hemodynamic management of the patient.
Summary: Menezes CC, Peceguini LAM, Silva ED, Simões CM -Use of Sugammadex after Neostigmine Incomplete Reversal of RocuroniumInduced Neuromuscular Blockade.Background and objectives: Neuromuscular blockers (NMB) have been used for more than half of a century in anesthesia and have always been a challenge for anesthesiologists. Until recently, the reversal of nondepolarizing neuromuscular blockers had only one option: the use of anticholinesterase agents. However, in some situations, such as deep neuromuscular blockade after high doses of relaxant, the use of anticholinesterase agents does not allow adequate reversal of neuromuscular blockade. Recently, sugammadex, a gamma-cyclodextrin, proved to be highly effective for reversal of NMB induced by steroidal agents.
This descriptive study allows us to state that in the hospitals evaluated the majority of anesthesiologists uses resources to minimize eventual repercussions of controlled mechanical ventilation. This data can orient the development of continuing medical education programs in mechanical ventilation associated with anesthesia aiming to safety and improvement of patient care.
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.
