When a patient is receiving mechanical ventilatory support, there are certain drugs and medications that are required in order to provide comfort and facilitate ventilation. So if you’re searching for the drugs used in mechanical ventilation, you’re in the right place because that is what this study guide is all about.
The two primary reasons that drug therapy is used during mechanical ventilation is for sedation and patient comfort and also for airway management.
With that said, in this guide, we’re specifically going to focus on the medications for sedation and patient comfort. So if you’re ready, let’s go ahead and dive right in.

What are the Common Drugs Used During Mechanical Ventilation?
Sedatives affect the brain in a way that helps the patient relax which reduces stress, anxiety, and agitation. Analgesics provide relief from pain. Paralytics are used to assist with intubation and surgery, and relieve laryngeal spasm.
Some patients may be able to tolerate mechanical ventilation without drug therapy, however, they are often required in order to minimize stress and anxiety.
Examples of Drugs Used in Mechanical Ventilation:
Atracurium besylate (Tracrium)
What are Neuromuscular Blocking Agents?
Also referred to as Paralytics, this type of medication blocks neuromuscular transmission at the neuromuscular junction. This causes muscular paralysis of the affected skeletal muscles. They are commonly used for paralysis in rapid sequence intubation, tracheostomy, and to facilitate mechanical ventilation in patients with an acute lung injury or ARDS.
Otherwise, it may be risky to use neuromuscular blocking agents during mechanical ventilation because of the risk of prolonged neuromuscular weakness and the need for continuous heavy sedation.
Mechanical Ventilation Drugs Practice Questions:
1. What are the 3 types of drugs needed during ventilation?
Neuromuscular blockers, Sedatives, and Analgesics.
2. What are some examples of Neuromuscular blocking agents?
Succinylcholine chloride, Vecuronium, Pavulon, Rocuronium, Atracurium, and Cisatracurium.
3. What is the action of Succinylcholine chloride?
It is an ultrashort-acting depolarizing agent.
4. What are some examples of drugs used for sedation and analgesia?
Lorazepam (Ativan), Midazolam (Versed), Morphine, Dilaudid, Fentanyl, and Propofol.
5. What are Metaproterenol (Alupent) and Albuterol (Ventolin)?
They are short-acting bronchodilators used to reverse acute bronchospasm and are given in 15-30 minute intervals until effective. You may give them with oxygen to increase tissue perfusion.
This book (in paperback format) has sample TMC Practice Questions on mechanical ventilation.
6. What is Methylprednisone (Solu-medrol)?
It is a corticosteroid used along with bronchodilators to decrease inflammation, acute respiratory failure. It requires 4-5 days of use before it is effective.
7. What is Dexmedetomidine (Precedex)?
It is a sedative, amnesic, and analgesic. It is indicated for short-term sedation of a patient needing mechanical ventilation. The patient can be easily aroused and then return to a sleep-like state. Side effects include nausea, bradycardia, and hypotension.
8. What are Opioids?
They are used to decrease pain in patients with acute respiratory failure that are on the mechanical ventilator. They are given with sedation and paralytics.
9. What is Acetylcholine?
It is an ester that plays a role in the transmission of nerve impulses at synapses and neuromuscular junctions. It is metabolized by the enzyme cholinesterase. Too much or too little of acetylcholine at the motor endplates may lead to muscle blockade.
10. What is Antimemetic?
It is used for preventing nausea and vomiting.
11. What is Anxiolysis?
It is used for diminishing anxiety.
12. What are Barbiturates?
A group of drugs that depresses the central nervous system. They have many adverse effects, including alteration of the respiratory rate, heart rate, blood pressure, and temperature. They are used in seizure disorders and intracranial pressure imbalances.
13. What are Benzodiazepines?
A group of drugs with strong hypnotic and sedative actions. They are used mainly to reduce anxiety and induce sleep.
14. What are Cathartic agents?
Active purgatives used to produce bowel movements.

17. What are some examples of inhaled steroids?
Dexamethasone (Decadron, Respihaler),
18. What are Depolarizing agents?
Drugs that prolong the depolarization phase of muscle contraction, thus rendering the repolarization/depolarization sequence (normal mechanism for muscle movement) impossible and causing muscle blockade. An example is succinylcholine (Anectine, Quelicin).
19. What is Dexmedetomidine (Precedex)?
An intravenous drug that offers anxiolysis and analgesia but respiratory depression.
20. What is Gamma-aminobutyric acid (GABA)?
A major central nervous system inhibitory transmitter that regulates the chloride ion channel and hyperpolarizes the neurons. Once the neurons are hyperpolarized and become resistant to repeated depolarization, sedation results.

A drug for the control of delirium in mechanically ventilated patients.
22. What does inotropic affect?
It affects contraction.
23. What is Nitric oxide?
Inhaled nitric oxide or (iNO)therapy has been used to treat persistent pulmonary hypertension and hypoxemic respiratory failure of the newborn, respiratory distress syndrome and hypoxemic respiratory failure of older infants and children, and acute respiratory distress in adults.
24. What are nondepolarizing agents?
Drugs that compete with acetylcholine for the receptor sites at the motor endplates, thus blocking the normal action of acetylcholine and causing muscle blockade.
25. What are some examples of nondepolarizing agents?
Vecuronium bromide (Norcuron) and pancuronium bromide (Pavulon).
