- What is general anesthesia?
- A reversible, drug induced loss of consciousness and sensation affecting the whole body.
- Stage ____ of general anesthesia is the stage of analgesia, when the patient is still conscious but pain is dulled.
- 1
- Stage ____ of general anesthesia is the excitement (delirium) stage, marked by irregular breathing and involuntary movement.
- 2
- Stage ____ of general anesthesia is surgical anesthesia, the plane where the operation is safely performed.
- 3
- Stage ____ of general anesthesia is medullary paralysis, a dangerous level of anesthetic overdose.
- 4
- What is the main danger of stage 4 (medullary paralysis)?
- Respiratory and cardiovascular failure from anesthetic overdose.
- What should the surgical technologist do while the patient is being induced?
- Stay still and silent near the field so nothing distracts the anesthesia provider.
- What is preoxygenation?
- Having the patient breathe 100 percent oxygen to build an oxygen reserve before the airway is secured.
- What is rapid sequence induction (RSI)?
- A fast induction technique for patients at high aspiration risk, giving an induction drug and a paralytic together.
- What is the purpose of cricoid pressure (Sellick maneuver)?
- Compressing the cricoid cartilage against the esophagus to reduce the risk of aspiration during intubation.
- Name a commonly used intravenous induction agent for general anesthesia.
- Propofol.
- What is the purpose of an endotracheal tube?
- To keep the airway open and allow controlled ventilation during general anesthesia.
- What instrument is used to view the vocal cords during intubation?
- A laryngoscope.
- What is the purpose of neuromuscular blocking agents (muscle relaxants) in anesthesia?
- To relax skeletal muscle, easing intubation and improving surgical exposure.
- Name a drug used to reverse neuromuscular blockade at the end of surgery.
- Neostigmine.
