Neuromuscular blockade

This trial tests whether an experimental drug called HRS-9190 can safely and effectively relax muscles during general anesthesia for elective surgery. It compares HRS-9190 to a standard muscle relaxant, rocuronium, in about 320 adults. The study measures how well the drug enables…

This study looks at whether two different devices, acceleromyography and electromyography, give matching readings of muscle recovery after anesthesia. It involves adults having gallbladder surgery who receive muscle relaxants. By measuring the train-of-four ratio with both device…

Researchers are studying whether the amount of a muscle relaxant called rocuronium affects how well a laryngeal mask airway works during general anesthesia. The laryngeal mask is a soft tube placed in the throat to help patients breathe, an alternative to a traditional breathing …

This study looks at two ways of using a muscle relaxant drug (rocuronium) during spine surgery. One group gets a low dose throughout surgery, the other stops the drug after the start. The goal is to see which approach gives clearer nerve signals for monitoring the spinal cord. Ab…
