David Fraser Senior Member I do not know if this has been covered elsewhere but I thought it relevant to put somethimg here with the mention of "nanoparticles" of Aluminium. They reached the following conclusion. None of these nanoparticles caused the induction of nitric oxide, TNF-alpha, or MIP-2, important components in inflammatory responses.
The last 10 years or so has seen an evolution of the kit, ultrasounds and techniques… so my current set up and routine bears little resemblance to that when I trained.
This article is an attempt to consolidate some useful tips, thinking, and evidence that can shape our practice. In reality, we all need to have a few tricks in our toolbox to do this well. CVC insertion is a core skill for ED and Anaesthetic practice — it should be part of the basic training.
This is a complex skill that requires close supervision to learn well. I will come back to this point repeatedly as this is the key to avoiding harm with CVC insertion. Having a dedicated assistant is super helpful: This should be routine for sterile lines in all but the most urgent scenarios.
WHAT Your kit will be largely determined by local policy. It has all the prep gear, a large adhesive drape with a decent size fenestration in it. You need a large trolley to lay out all the gear.
Ideally, one that is 3 feet wide. A swab and lignocaine syringe if you are doing a superficial cervical plexus SCP block… not on the sterile setup. A 3 or 4 lumen CVC. I have never regretted moving the patient to a well lit, open area where one can: Doing this in a small aircraft is nearly impossible — so we often place CVCs in anticipation of transfer where multiple infusions and reliable access are needed.
This is the polite thing to do if we are working with our aeromedical team well. It is somewhat easier to discuss the reasons NOT to place a central line.
Here are a few…. Large bore peripheral lines suffice for the vast majority of hypovolemic cases. We have moved away from large volumes of crystalloids in trauma, sepsis, and most medical Resus scenarios.
In my opinion, there is a risk of overdoing Resus fluids if we have lines that can quickly deliver a litre. Sure, we can restrain ourselves, but in practice, it is common to see a drip left wide open and a litre go through before a thought is given.
There are better, faster ways to get access in a rush, or where the patient has limited peripheral veins. Some docs might have experience with placing a large gauge central line eg.
However, this is not the time to learn! Monitoring CVP was super cool when I trained.
In complex heart disease. I usually opt for a central line if a transfer is happening- as they will get one anyway and this gives the transfer team a good, robust access point. Difficult peripheral access was a reason to place a central line in my training….
So I think that we can avoid central lines for this indication if the option to place a midline or PICC is available.
So then… who should get a CVC? Patients who are likely to need ongoing vasoactive or other infusions will benefit, and the nursing will be easier, especially where multiple drugs with compatibility issues, antibiotics etc are being used.
Where frequent blood sampling is needed eg, bad DKA, electrolyte manipulations, toxicology etc I reckon a CVC can be a humane way to go. Gives good access and avoids a course of phlebotopuncture.
If that is looking likely then place a CVC early to get maximum benefit ie. Usually there are numerous reasons to put in a CVC.
Wengart Aircraft must incorporate “doing it right the first time” in their TQM objectives and change the corporate culture so there is a reward for exceeding internal and external client’s needs (Brown, , p. . Anaesthesia & Aviation How many times have I heard people (usually other doctors) liken anaesthetics to flying a plane - 99% boredom and 1% sheer terror? you've got to know how to implement actions in case of disaster. Scott Weingart has recently podcasted on the concept of logistics vs strategy, and trimmed the aircraft for a shallow. exposure data for use in cohort and case-control epidemiologic studies and exposure assessments.

So it makes sense if it is making the patients experience better and safer… but you need to weigh that against the risk of injury from insertion see risks below WHICH SITE?

. This brings us to the curious case of Board Chairman Dan Weingart, thinking like a fiduciary, suggested there should be a note about the possibility of a shutdown because it was a foreseeable risk.

Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS™) is a systematic approach developed by the Department of Defense (DoD) and the Agency for Healthcare Research and Quality (AHRQ) to integrate teamwork into practice.
Aircraft Performance In this chapter we will make the connections between aircraft performance and propulsion system performance. For a vehicle in steady, level flight, as in Figure , the thrust force is equal to the drag force, and lift is equal to weight.
