Incidence of postoperative residual curarization in the post-anaesthesia recovery unit

This study is looking at how often patients have leftover muscle weakness from anaesthetic paralysing drugs (muscle relaxants) when they wake up in the recovery room after gynaecological, breast, or cosmetic surgery. This lingering weakness, called residual neuromuscular blockade, can cause breathing difficulties. The study will also track side effects like nausea and vomiting, and how long patients stay in the recovery room. You may be eligible if: - You are a female aged between 21 and 80 years - You are having a general anaesthetic for major gynaecological, breast, reconstructive, or aesthetic surgery - You received a muscle-relaxing drug (neuromuscular blocking agent) as part of your anaesthetic - Your anaesthetic health risk is classified as ASA I, II, or III You may NOT be eligible if: - You are younger than 21 years of age - You have a neuromuscular disease that affects muscle function - You are on medications known to affect muscle-nerve communication Talk to your doctor about whether this trial might be right for you.
