  • No evidence to support contraindication in penetrating eye injuries
  • N.B. Myasthenia Gravis- theoretically need more succ to induce vs nondepolarizing agents which have a prolonged effect.
  • This is 2/2 to lack of post-synaptic receptors, i.e. succ cannot potentiate a reaction 2/2 too few receptors.
  • Vs. it takes few "molecules" of roc/vec to block the few remaining functioning receptors.
  • Overall, most practitioners tend to avoid succ in all patients with possible neuromuscular disease.
