The document discusses anesthesia for thymectomy surgery to treat myasthenia gravis. It analyzes 124 patients who underwent this surgery between 2004-2012 at a hospital in Vietnam. The patients were divided into two groups: one group where non-depolarizing neuromuscular blockading drugs (NMBDs) were used, and one group without NMBDs. The results showed that patients who received NMBDs had longer times to spontaneous ventilation after surgery, higher rates of postoperative mechanical ventilation use, longer recovery room stays, and higher ratios of postoperative respiratory failure compared to patients who did not receive NMBDs.
