Should first give patient adequate trial of antidepressant medications (inc: trial of several drug classes and augmentation) Pt should have sx requiring immediate tx (i. e. psychiatric sx during preg and catatonia, especially malignant catatonia) Ect should be used as a tx bump to get patients to a spot where an add will work to tx their depression. 70-80% efficacy w/ catatonia being esp responsive (ect considered effective in. Short acting iv anesthetic to induce unconsciousness (common: methohexital, barbituates) Brief electrical currents sent thru electrodes causing generalized seizures.

Sitting in the dentistâs chair, Larry nervously thought about hisdental procedure which involved drilling out the decayed area ofhis tooth and then inserting an amalgam (filling). Before theprocedure, the dentist ânumbed the areaâ by injecting a localanesthetic into the nerve pathway of the tooth. Much to Larryâssurprise and relief, he felt no pain during the drilling andfilling. Explain how the anesthetic prevented the transmission ofpain sensations to the brain.

1. As a Nursing student in Advanced Human Anatomy, you were ableto observe a total hip replacement. While the O.R. personnel whereprepping the patient for the surgical procedure, theanesthesiologist assumed (rightly so!) that you had some physiologybackground. As such, she launched into the following proceduralexplanation: The patient will need to be intubated, therefore hewill be given a single dose of the neuromuscular blocking agent,succinylcholine to provide muscular relaxation during the surgeryand to facilitate the insertion of the endotracheal tube. Theanesthesiologist asked you the following:

a) Beginning with depolarization at the neuromuscular junction,describe the normal sequence of events which lead to musclecontraction. (10)

b) What prevents acetylcholine (ACh) from accumulating in theneuromuscular junction and causing a sustained contraction in anormal individual? (3)

c) Succinylcholine acts as a depolarizing agent that preventsrepolarization of the nerve. Therefore, no further ACh is releaseduntil the drug is cleared. Name another site within theneuromuscular junction that might be affected to prevent musclecontraction. (Hint: curare acts by this mechanism) (2)
