A fourteen center study enrolling 1623 trauma patients (53% penetrating) comparing cold-stored whole blood vs. blood component products found no difference in AKI, thromboembolism, or pulmonary complications. And more interestingly, patients receiving whole blood were 48% less likely to die than those receiving standard blood component products. Add this data point to a growing trend toward cold-stored whole blood for trauma patients.

Manageing the airway of a trauma patient presents difficulties because of both anatomic and physiologic derangement.
The Bottom Line: Trauma patients requiring intubation are a challenge and should be managed by the most expereinced person in the room. No study shows superiority of direct vs.video laryngoscopy. Use the technique you are most facile with and develop more techniques through courses, mentoring, and expanding your repertoire in less ill patients first. Use induction agents with lower liklelihood of causing hypotension like Etomidate and ketamine (avoid propofol and benzodiazepenes). Avoid hypoxia, hypotension and hypocarbia by resucitating as much as possible prior to intubation (use blood products and pressors where appropriate). Have a plan, a back up plan, and know when to switch to a surgical airway approach. This ia a low frequency, high risk proceedure. Mentally visualize yourself doing this proceedure regualrly to create a comfort level when it is actually needed.
PEARLS:
1. Blood/Emesis A. Use a double suction set up with one suction placed into the airway near the esophagus and then moved to the left of the mouth with the second used by the intubator to clear their view.
B. If you can't visualize becaue of vomit/emesis it is very likely BVM and super glotic airways are not going to be possible and you will need to move to a surgical (front of neck) airway.
2. Limited Jaw Opening Cervical collars can impede jaw opening. Loosen/open the collar to allow more jaw opening. Studies show that there is limited movement of C-Spine when the intubator uses caution not to flex the neck during intubation meaning the collar does not have to be in place. No study shows diret or video laryngoscopy to be superior.
3. Blunt or penetrating neck injury Highest level of difficulty. Should be most expereienced intubator. Can use an awake intubation technique if you are adept at this method. Go with the airway approach that gives YOU the best first pass success chance. Another situation where BVM or suprglotic airway device may not work and requires surgical airway. May require low tracheostomy approach.
4. Hypoxia Avoiding hypoxia is a must especially in traumatic brain injured patients. Pre-oxygenate and use the airway technique that is going to give you the best first past chance of success.
5. Hypotension: A. Resuscitate with blood products as much as possible before intubation. B. Use induction agents that are the most hemodynamically neutral such as Etomidate or Ketamine (safe in head injury patients!)
6.. Hypocarbia: Congrats on getting the tube! Now slow down your bagging. Hypocarbia leads to increased injury in traumatic brain injured patients.

- High-quality CT is adequate for clearing c-collar in obtunded patients.
- A follow-up exam before discharging the patient strengthens your decision making and documentation.
- MRI can be reserved for high-risk patients, patients who are being admitted to surgical critical care units, and those who have residual findings once alert.

Lidocaine with Epinephrine and it use on Fingers and Toes
It has been taught for a long time that Lidocaine with Epinephrine should not be used on fingers, toes, ears and nose [There has to be a kid's song in there somewhere] due to the risk of vasoconstricition/vasospasm and possible digitial infarcation.
The short story is that this practice is not supported by the literature, and there are now numerous publications that have shown that lidocaine with epinephrine is safe for use on the finger tips. It turns out the the original case reports were submitted with procaine and epinephrine and not lidocaine with epinephrine. Most of the cases of digital infarction where with straight procaine that is now thought to have been contaiminated or too acidic pH close to 1 when injected.
The effects of epinephrine last approximately 6 hours. This time is well within the accepted limit of ischemia for fingers that has been established in digitial replanation.
So why use Lidocaine with Epinephrine:
- Provides a longer period of anesthesia
- Decreases bleeding which:
- Improves visualization of tendons and underlying structures
- Makes repairs easier
- Decreases need for a torniquet
