Techniques for smooth wake-up

Specialties CRNA

Published

For CRNAs,

Everyone seems to have a different technique for emergence. Could the CRNAs out there share their technique to wake patients after general anesthesia, especially GETA. I know some CRNAs who like to transiton from volatile gas to a propofol drip towards the end of the case, while some slowly decrease the gas just before the case ends. I've also seen in clinicals where a couple of CRNAs like to have the patient spontaneously breathing well before decreasing the gas. Could anyone discuss their techniques and the advantages and disadvantages?

Thanks,

cube, SRNA

If you have an anesthesia machine capable of Pressure Support, I highly recommend using this at the end of your case. You can get them breathing comfortably on PS and titrate your narcotic of choice and they wake up very nicely.

I decide if I want to do a deep or an awake extubation. The most important thing is to do one or the other, not extubate in between. If there is a need for an awake, then I time turning down/off the agent with the progress of the surgery while assuring the muscle relaxation is reversed. Once I'm sure surgery in complete I'll turn off agent while increasing the O2 flow and maybe increasing the minute volume to blow agent off faster. Once they cough I take them off the ventilator and hand ventilate until they respond to commands and demonstrate muscle strength.

If I decide on a deep extubation I'll let the CO2 rise the last 15-20 minutes of the case to the mid40's by reducing the minute ventilation. Usually they will start breathing, and I'll titrate narcotic to the resp rate. (If they need muscle relaxation until the very end, I might shorten this part up) I'll continue to assist ventilation until the procedure is completed and at no time is the agent level reduced. If they start coughing with suctioning, I'll increase agent and let them breath themselves down until they are deep enough. Once they don't cough with suctioning, and have a good respiratory pattern, I pull the tube. Then they need a good jaw lift to keep the airway open and be quiet with the airway until you are sure they are going to maintain respirations (don't be moving the head around, suctioning etc). Some people don't like deep extubations, but it can work well in the right situations.

I pretty much get all of my patients back breathing as soon as it is feasible (after relaxation no longer required, etc...). I like to use SIMV or PS at first, then let them breathe spontaneously. While they are breathing, I titrate my narcotic of choice to achieve a respiratory rate of about 6-10. I have found that if the patient is comfortable and has enough narcotic on board, they tend to wake up much more smoothly.

the tube in their throat or pain is the reason for most rough emergences that can be dealt with by deep extubation or timely narcotics at the end.

TIVA if you arent a cheapskate...Isoflurane can give a nice wake up as opposed to desflurane...gives you a little more time to titrate some narcotics...of course, your attending may have a problem with any of this since you are an SRNA. Best advice...don't worry about how rough the patient wakes up...it is surface level, the important thing is that the tube comes out at the right time...better later than too early if you are still a student. If it gets to a point where the patient is a danger to himself or others, and they are still intubated, don't be afraid to give a few ccs of propofol....

anyone else?

Shut your gas off early and use bumps of propofol. Titrate your propofol with their vital signs. Nice smooth wakeup and you get coverage for nausea as well.

Do any of you CRNAs use Precedex? We've just started using it in our post-op open hearts in a case-by-case basis (those with rough emergence, poor vent tolerance). I like what I've seen so far, but the adverse effects have needed close watching. They say it should decrease the narc need and shorten our post-op extubation times. Any other recommendations for non-anesthesia personnel who extubate?

Get em breathing, titrate some morphine in for RR 8-12, deep extubation they wake up wondering what happened.
