Sedation After an Advanced Airway
Objective: Paralysis is not sedation. After an advanced airway, give protocol analgesia and sedation, and watch the blood pressure. This page lists no doses.
Why this matters
Paralysis is not sedation. After succinylcholine or rocuronium, a patient can be awake, in pain, and unable to move or breathe.
The drugs that treat awareness also drop the blood pressure. Give what the protocol names. Ventilate well. Watch the pressure. This page lists no doses. The card has the amount.
- After a paralytic, plan analgesia and sedation before you lose the thought. The protocol owns the names and the doses.
- A falling blood pressure after the tube is common. Have a shock plan. Do not leave the patient paralyzed and awake because the pressure is low.
- Keep waveform capnography on. Fighting the tube, or a cleft in the waveform, means reassess sedation. It does not mean another paralytic by itself.
- The tube is in. The waveform is on. Next is pain control and sedation per protocol.
- The pressure is low. I am using the agent the shock airway card allows.
- I am not using a second paralytic as a sedative.
Clinical sequence
- Confirm the airway with waveform and chest rise. Secure the tube. This lesson starts after post-intubation care has a patent airway.
- Check the blood pressure. If the patient is in shock, use the sedative and analgesic the protocol prefers for low pressure, or call medical control. Do not leave the patient paralyzed with no plan.
- Give analgesia and sedation in the order the card writes. Many pathways treat pain first and then sedate. Follow the card. Say the drug and the dose out loud.
- Ventilate at the rate and volume you were trained to use. Do not bag faster to suppress the patient. Low carbon dioxide and high pressure in the chest make shock worse.
- If the patient starts to move, or the waveform shows patient effort, that can be pain, fear, or a wearing paralytic. Reassess sedation. Another paralytic without sedation repeats the original harm.
Teaching points
- Awareness under neuromuscular blockade is a recognized harm in anesthesia and in emergency intubation. The prevention is a plan. It is not a dose you invent.
- Ketamine, benzodiazepines, and opioids are not interchangeable. Their doses are not on this page. The ketamine and benzodiazepine lessons are framing, not orders.
- Document the time of the paralytic and the time of the first sedative. A long gap is a quality problem you can see on the chart.
Common errors
- Paralysis with no follow-up sedation because the patient looks comfortable.
- A large benzodiazepine dose in a patient who is already hypotensive, with no plan for the pressure.
- Turning off capnography because the alarm is noisy.
Practice
One-minute check
The tube is confirmed. The paralytic was given four minutes ago. Blood pressure is 82 systolic. Say what you will not assume about comfort, and which document owns the next drug. Those numbers are a practice scene. They are not a dose.
