Frequently Asked Questions

Why monitor NMBAs?

  • 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 anaesthesia-related deaths are directly or indirectly attributable to PORC.

What is attributed to cause the fading observed during TOF or DB?

  • The reason for this is attributed to the binding of non-depolarizing neuromuscular blocking agents to presynaptic acetylcholine receptors, resulting in inhibition of the recruitment of Ach from the reserve pool.

What makes Sugammadex more effective than other reversal agents?

  • A minimum of spontaneous recovery does not need to be present before Sugammadex can be administered. Even the deepest neuromuscular blockade can be reversed rapidly within one to two minutes.
  • Fewer autonomic side effects are anticipated with Sugammadex.

The Stimpod NMS450X continually shows a reading of 100% even though the NMBA was injected – Why?

  • It could be because a depolarizing NMBA was injected.

The device showed that the patient was fully recovered, suddenly the TOF ratio dropped again – Why?

  • It could be that the core body temperature of the patient dropped again after recovery was observed.
  • In order to prevent PORC patients should only be assessed for residual NMBA once core has reached a temperature of greater than 36 °C.
