The present research project aims to evaluate the incidence of residual neuromuscular block in the post-anesthetic recovery room in patients who underwent general anesthesia with mechanical ventilation. It is known that neuromuscular blockers are drugs that interrupt the transmission of nerve impulses at the neuromuscular junction causing muscle paralysis. In addition, they facilitate endotracheal intubation during anesthetic induction and allow for adequate surgical management.
There are several adverse effects resulting from their use, among them: The occurrence of vagolytic and sympatholytic activities that cause cardiovascular alterations or autonomic stimulation. Monitoring the levels of these blockers is of paramount importance because it allows the titration of the drug. By relaxing and paralyzing the muscles, postoperative weakness due to the absence or incomplete performance of the antagonists of this drug is frequent. This situation is known as postoperative residual neuromuscular block.
When it comes to the anesthetic practice to evaluate such situation, the patient's clinic is often the only alternative. The safe use of neuromuscular blockers requires monitoring to qualify muscle relaxation by being measured from a known monitor of four stimuli or Train of Four (TOF).
The residual neuromuscular blocker influences possible clinical complications that may lead to increased morbidity and mortality in the postoperative period. Thus, this project aims to identify the incidence of residual neuromuscular block in the postanesthetic recovery room in order to reduce the cardiorespiratory complications resulting from the use of the adenos polarizing neuromuscular blockers.
