Paralytics are used to secure the airway during induction, but they are not kept in place throughout the cryoablation. The procedure relies on precise catheter control and, in some cases, monitoring of diaphragmatic or phrenic nerve function. Ongoing neuromuscular blockade would mask important signs, hinder rapid recovery, and complicate airway management if issues arise. Using a short-acting paralytic for induction provides a safe airway without leaving the patient paralyzed during the energy delivery, and any necessary suppression of movement during the procedure is usually achieved with sedation/analgesia rather than continuous paralysis.
