• Even moderate Post Operative Residual Curarization (PORC) decreases chemoreceptor sensitivity to hypoxia.
  • PORC is associated with impairment of muscles of the upper pharynx and upper oesophagus leading to regurgitation and aspiration.
  • Reduced upper airway volume or partial airway collapse
  • Significant risk factor for the development of pulmonary complications – increased morbidity and mortality
  • Research shows that almost half of anesthesia-related deaths are directly or indirectly attributable to PORC.
