Spinocerebellar tract Posterior spinocerebellar tract: Ascends and enters to ipsilateral cerebellum via ipsilateral inferior cerebellar peduncle Anterior spinocerebellar tract: Ascends and enters…
Atropine induced paradoxical bradycardia is the sinus bradyarrhythmia following low-dose atropine resulting from the paradoxical slowing in the sinoatrial (SA) node discharge rate. Mechanism of Atropine Induced Paradoxical Bradycardia Central vagotonic effect (blocking M1 acetylcholine receptors in parasympathetic ganglion controlling SA node) of atropine which, at higher doses, is masked…
Priming Administration of a small sub-paralyzing dose of non-depolarizing muscular blocking agent (usually 10% of the intubating dose) is given 2-4 minutes before administering a 2nd large dose for tracheal intubation to accelerate the onset of non-depolarizing NM blockade by 30-60 seconds. Mechanism and Concept of Priming 2 theories have…
