What are the criteria for intubation? I find it very confusing, when should I intubate and when not?
Absolutely. I would intubate anytime I felt like the patients breathing may be compromised..anesthesia prior to surgery or clinical evidence of brain injury.At some point before the surgeon starts the operation.
Criteria from Basics of Anesthesia
*Provide a patent airway
*Prevent inhalation (aspiration) of gastric contents
*Need for frequent suctioning
*Facilitate positive-pressure ventilation of the lungs
*Operative position other than supine
*Operative site near or involving the upper airway
*Airway maintenance by mask difficult
What about being super-combative in the trauma bay? That's earned a tube a few times in my experience....not exactly good medicine, but I have to admit that I was happy with the results.......
Usually you have to have a good reason for doing an intubation, (and the accompanying sedation), because residents usually should call their attending, and then make their case for intubation. A patient who is combative in ED may or may not need intubation. Say a patient is intoxication, and broke several ribs and was high risk for falling out of the bed in the ED and getting a pneumothorax or a patient who is at high risk for aspiration, and you want to protect the airway, then you would intubate (which again is not without risks, so you must weight whether the benefits outweigh the risks). Not all/most combative patients in the ED are intubated. Just because a patient is being supercombative doesn't give you the right to sedate and intubate them, which has a risk of ventillator associated pneumoniae if you have trouble weaning them later . . . First, I think you would get a psychiatry consult, then, depending on institution use perphaps "chemical restraints" like IM haldol, and/or ativan. . .

You guys all have such funny perspectives on this.
I thought the indications were (not an all-inclusive list and oversimplified, this is just for the basic idea....):
- < 26 weeks for prophylactic surfactant
- CDH Dx'd in utero
- NEC/sepsis with significant apnea
- HMD needing surfactant
- low apgars not responsive to bagging
Oh, you weren't talking about neonates?
In that case, I have no idea.

Your response tells me that you haven't spent a lot of time in an adult Trauma Bay.
Patients who are combative in the trauma bay are often drunk or intoxicated with illegal substances. They may have an overlying head injury. They are not kept intubated any longer than to sober them up and be cooperative; this is usually just a few hours. The risk of VAP is exceedingly low in this situation. Trauma patients can also be combative due to severe hypoperfusion secondary to fluid losses...a patient this severely injured often warrants intubation regardless of his mental status (or shall we say, in addition to).
There should be no problems weaning an otherwise healthy patient - if there is, its probably because they have a lung contusion or other injury in which case they have probably benefitted from the intubation. Head injured patients with a GCS of 8 or less mandate intubation according to ATLS - this is not done for the convenience of the medical staff.
For patients wih GCS greater than 8, I DO have the right to sedate and intubate the patient in the trauma bay if they are being a danger to themselves and others. I've seen medical personnel be injured by the patients while attempting to take blood or do a physical exam. These patients are often resistant to chemical restraints and without knowing what illegal substances they've taken I'm a bit hesitant to give them benzos, especially in patients with head injuries. I let my anesthesia colleagues do an RSI and decide which meds are best to use for the situation.
I would NOT generally intubate a drunk patient with a few broken ribs who was sleeping it off in the ED just to protect them from a potential PTX (which after all doesn't necessarily cause respiratory embarassment or need for tube thoracostomy) unless he/she was a danger or had a GCS of 8 or less. Risk of aspiration? Perhaps but a NGT would probably do the patient better if he was able to protect his airway - too drunk to do so? Then yeah, he probably gets to smoke the peace pipe for awhile.
Calling a psych consult? Good idea if its needed (ie, not due to drugs, alcohol or head injury) but in most cases, getting a psychiatry resident down to the Trauma Bay in expedient time would be a miracle. Not a reason to defer the consult obviously, but in most cases the patient isn't combative because of a psychiatric illness but rather self-induced chemically (which will wear off) or because of their traumatic injury (which also doesn't need a psychiatrist).
Traumas in most Level 1 centers are run by senior residents who do not wait for the attending to show up or answer a page before making the decision to intubate. Even if the attending is there, its still the resident's call. If not there, I'm a little too busy to call the attending with the report until everything has settled out. I follow ATLS protocol with a modicum of experience and common sense. I have never had an Anesthesia attending question my request for intubation, either...I suspect in most cases this is true for others in the same postion. We aren't wily-nily intubating people.

and patients who are EtOH intoxicated are a setup for aspiration pneumoniae anyhow. It would be interesting to see a study on the outcome of ventillated EtOH withdrawl patients who are ventillated, versus those who are not, but I would guess it is used to rarely that it would be hard to study.
How would being a "setup for aspiration pneumonia" make you less likely to intubate? Maybe I don't completely understand what you mean, but I would think that aspirating/having possible airway compromise would earn you a tube faster. Besides establishing a protected airway, it would allow you to bronch/possibly evacuate some of that aspirate.
Also, the comment about benzos and withdrawal is kind of odd. Sure, once the patient has been assessed and treated, you would give low-dose benzos for withdrawal, but that wouldn't factor into my decision on what to give the acutely traumatized patient in the trauma bay.
Trust me, plenty of trauma patients receive "chemical restraints," or Vitamin H as I like to call it. I personally start out with 5 of haldol and 2 of versed. There are still plenty of situations where intubation is justified, however, and often the chemical restraints rob the patient's respiratory drive and lead to a tube. Nobody gets intubated without getting benzos first. I think that would be very difficult to perform on a fully awake patient.
Not all/most combative patients in the ED are intubated. Just because a patient is being supercombative doesn't give you the right to sedate and intubate them, which has a risk of ventillator associated pneumoniae if you have trouble weaning them later . . .

***I would be worried about how to justify intubating a non-trauma, non-respiratory distress, belligerent & combative patient for the sole purpose of having a patient that is easier to control, if something went wrong, i.e. pneumothorax, and perhaps cardiopulmonary arrest.**
I postulate that such a maneuver might significantly increase the risk of aspiration pneumoniae in an alcoholic.
I am postulating that intubating an alcoholic patient with alreay depressed immune system may introduce bacteria that are not cleared, and if done for only a couple of hours will obviously not decrease the risk of aspiration in a normal appearing alcoholic patient.
Of course a trauma situation is different where you might suspect cervical fx, then I would see you would need to intubate a patient who is in danger of pithing themselves.
I think that what I originally protested was a blanket statement saying that combative patients in ED can be intubated just because they are combative. I have seen many many beligerent/combative EtOH intoxicated patients walking around a trauma cursing, i.e. being combative, but no hx of head trauma per patient, no hx of trauma, no cervical tenerness, etc . . . a head CT would often be done to rule a bleed causing symptoms, but if after thorough history and exam there is no reason to suspect a cervical neck fx then imaging studies aren't done, nobody runs in and yells that this man should be intubated because we have to rule out a cervical neck fracture. Obviously is a patient is collared coming in then you need to maintain in-line cervical stability by any means possible. . . again as I distill my statement:
***I would be worried about how to justify intubating a non-trauma, non-respiratory distress, belligerent & combative patient for the sole purpose of having a patient that is easier to control, if something went wrong, i.e. pneumothorax, and perhaps cardiopulmonary arrest.**

Well, I certainly didn't want to be a know-it-all, I just didn't want people to get the wrong idea about intubation/sedation, the first goal of physicians is to do no harm. You by your own words seem to admit that intubating a patient who is being super-combative in the trauma bay is "not exactly good medicine, but I have to admit that I was happy with the results . . . ."
It appeared to me that you were indicating that intubating this patient was "not good medicine", which in my mind implies that anything medically critical has been ruled out. This really surprised me that a hospital would intubate a patient when it is not considered "good medicine" but just to be "happy with the results."
What could have been a reasonable talk about an important talk appears to have degenerated, I apologize if I am somehow responsible for that. I do think it is important to discuss rare complications of procedures especially when they may not be medically indicated. Most children with a viral illness like chickenpox who are given aspirin don't get Reyes syndrome, but we recommend against it and it has reduced dramatically a rare disease. Sometimes you have to do a careful evaluation and a certain management decision thousands of times to save the life of one patient over the course of a medical career, but in the end it is worth it.
How would you feel if you mother was intubated in the ED and that the intern thought that it was "not good medicine" but were "happy with the results."
You don't need to agree with me, but I wanted to clarify my position.
