Will pancuronium cause the death of the patient if not intubated?

Need ventilation. Pancuronium is a medication that causes neuromuscular blockade, meaning that it stops skeletal muscle from working. The heart will beat, but the muscles that control breathing will stop. Breathing must be supported while the medication is in effect. Breathing is usually supported with a breathing tube and mechanical ventilation, but mask ventilation or an lma could support breathing too.
Yes. Ince it is given the patients respirations must be supported either via intubation and mechanical ventilation or by another method of assisted ventilation.
