Why some patient has spasm after extubation?

Patients may experience spasms after extubation due to a combination of factors, including airway irritation, residual muscle relaxants, or underlying conditions such as bronchospasm or laryngospasm. The trauma from intubation can irritate the airway, leading to involuntary muscle contractions. Additionally, postoperative pain or anxiety can contribute to respiratory muscle spasms. Proper pre- and post-extubation management can help mitigate these risks.
