<prompt> Which is not a feature of non depolarizing block?Potentiated by magnesiumPotentiated by neostigmineRelatively slow onsetIn paial paralysis nerve stimulation shows fade  <response>: Non- depolarizing neuromuscular blocker is reversed by neostigmine. Several crude tests has been suggested to evaluate neuromuscular block 1. Head lift for 5 secs 2. Tongue protrusion 3. Hand grip 4. Ability to lift legs off bed 5. Hold jaw shut and prevent removal of tongue depressor.most sensitivecorrelate TOF Ratio- 0.9 For Recovery target TOF ratio 0.9 Residual paralysis Can occur after general Anaesthesia CF - Patient conscious , unable to breathe adequate tidal volume , motor weakness, desaturation Mn- suppo the ventilation Reversal agent Anticholinesterase Agent Neostigmine - it is reversible acetylcholinesterase inhibitor . This inhibition is present at all cholinergic synapses so has potent parasympathetic activity. Thus given accompanied with Atropine glycoprolate. Dose- 0.035- 0.05 mgkg Peak effect- 1 to 2 min Suggamadex Direct reversal agent Gama- cyclodextrin compound Binds with aminosteroid in molar ratio 1:1 Acts best against Rocuronium and vecuronium.
