Study Notes
Miotics, Midriatics and Glaucoma
- Miotics are drugs that constrict the pupil of the eye.
- Midriatics are drugs that dilate the pupil of the eye.
- Glaucoma is a condition where the pressure inside the eye increases, potentially damaging the optic nerve.
Stages of General Anesthesia
- General anesthesia involves a loss of consciousness and sensation, typically achieved through intravenous drugs or inhaled gases.
- The stages of general anesthesia are:
- Stage 1: Analgesia - patient is drowsy and relaxed but conscious.
- Stage 2: Excitement - patient may become agitated, confused, or delirious.
- Stage 3: Surgical Anesthesia - patient is unconscious and unresponsive to pain.
- Stage 4: Medullary Depression - patient's vital signs are depressed and may fail to respond to stimuli.
Classification of General Anesthesia
- General anesthesia can be classified into:
- Inhaled Anesthetics: These drugs are delivered via the lungs, such as isoflurane, sevoflurane, and desflurane.
- Intravenous Anesthetics: These drugs are administered through a vein, such as propofol, etomidate, and ketamine.
Sedative-Hypnotics
- Sedative-hypnotics are drugs that induce relaxation and drowsiness.
- Examples include:
- Benzodiazepines: (diazepam, midazolam)
- Barbiturates: (phenobarbital, pentobarbital)
