A little known tip about proper aspiration technique is shared in this dental anesthesia video. This video will refresh the general dentist on the proper way to aspirate prior to injecting which will lead to increased success and fewer complications.
In dental hygiene school we call this "aspirating on two planes"
This is a great video, thanks for sharing! I am a 4th year dental student and this is exactly how we were taught to do aspirations! Glad to know we learned it this way! Thanks for making this video doc!
Thank you so much for this video 🌸
loved it , thanks ✌
i did learn about double aspiration with rotation , i did not understand it why . Mainly was recommended when doing it to people with cardiovascular problems or pregnant woman when u need to be sure not to inject in vesel. Good tip
As always , very crucial information . Thank you
Thanks for watching! All the best!
Very well explained
Thank you teacher
Very helpful.
Nice, I had a false negative once, on a surgeon I was working too. heart started raising, but it passed
understood sir 👌
Between dental block and ring block, which one is more painful?
I learned about this in the Navy. Good video
Thanks for watching! Any other tips you can share from your experience there?
Is this a step that must be taken before giving the anesthetic or not, bc I have seen some doctors do not do it?
I mean is it important to aspirate?
Amazing info... I usually don't aspirate; can this fail my technique?
It could cause you to miss a block if you are injecting into a vessel instead of the tissues. This would be unlikely, but it could happen. All the best!
Hi. Can you recommend some techniques regarding aspiration because sometimes I feel like my thumb is too short that I cannot aspirate properly/ Thank you doctor
Jay Ann - try getting a syringe with a disc on it. This is specific for aspiration. You apply pressure to the disk. Alternatively, get an auto-aspirating syringe where you don't have to pull back on the plunger, you just let up on the pressure for a second and it aspirates for you. All the best!
Hello doctor. Your videos are amazing. Which cartridge syringe do you use? Would like to know. Where can l purchase the same
I believe these ones are Miltex? Don’t quote me on that, but I believe that’s it.
All the best!
Can you do a video explaining the bevel of the needle
What were you wondering about the bevel Mickey? All the best!
Use a harpoon style syringe and one is able to pull back and forth while aspirating.
Silly question, but what would your symptoms be if your dentist had done this by accident? If say the dentist was a newly qualified dentist? I never knew about this, as I never needed anything until recently, I had a little filling. I would have certainly mentioned it if I did know!!( Little bit of a worrier)
It's really not a huge deal in most cases. Quite frankly, regardless of a dentists experience level they are likely to inject into a vessel from time to time. The most common thing people would notice is your heart rate speeds up and you feel a bit unsettled because your physiologic state doesn't match up with your mental state. I've experienced it myself. This is from the adrenaline that's in the anesthetic and it typically only lasts for a couple minutes before the effects subside. All the best!
What happens if all the anaesthetic gets put into the bloodstream?
Great question - if you were to inject an entire carpule it is possible that you will effect the brain and heart in a negative way. Depending on the patient, they may experience anything from a rapid heartbeat (from the epinephrine), to a seizure, or even possibly cardio/respiratory depression that could be quite significant. Consider when you inject a drug, it takes a while for it to be absorbed and distributed throughout the body. Also, it gets metabolized throughout this process so you won't absorb the full amount. IV is 100% right away so the side effects are magnified. Kind of like if you gave a patient way too much anesthetic if that makes sense. All the best!
I got one 3 days ago and i got like a bumb in my mouth and it hurts when I touch it or burns im 100 percent sure it's where the needle was put when I eat something it starts burning or hurting is that normal?
Could be the opening where your saliva enters the mouth which originates in the parotid gland. It's a small bump on the inside of the cheek adjacent to the upper molars. Sometimes it will become infected, inflamed, or obstructed and it can be very irritating especially around meal times. If it persists, I would suggest visiting your dentist. All the best!
@@OnlineExodontia I had one a long time ago and it disappeared Idk how long it takes to disappear its very annoying when I eat I just hope it disappers like last time
I was very surprised my anesthesia almost didn't hurt at all; the needle was super small and fine,foctor applied the numbing spray,I felt very little discomfort! (And I do have phobia of going to dentists,but now it isn't that strong )
could we need to decrease from anesthetic carpule to make space to do aspiration during IANB injection or no need?
I hope I'm understanding correctly, but I would say that you must either pull back on the plunger if you're using an aspirating syringe (harpoon-style) or you must let off on the injection pressure with a self-aspirating syringe to see the positive aspiration. All the best!

I understood what you meant, but I meant that there is not enough space in the anesthetic ampoule because it is full of anaesthesia, so how can I do a backward aspiration? Do I need to empty part of the anesthetic ampoule so that there is enough space to do a backward aspiration?
@@user-xt9ey2kt8w The stopper in the carpules has room to move backward even before injecting, so you can follow the same guide as I mentioned to aspirate prior to injecting. If it's a self aspirating syringe, you can press on the ring on the barrel and it will perform an aspiration without injecting any solution. Hope that helps!
@@OnlineExodontia I got it , thanks so much doctor
they teach this now in dental school
Why not keep the needle turned down the first time so vessel wall doesn't stick to needle tip?
The reason for aspirating twice after rotating the barrel is to confirm the lumen in patent. The orientation of the bevel would not play a role in preventing the initial blockage. I imagine this is a very rare occurrence, as I can't say I've ever noticed it clinically. Wished to share however as it was something I came across! Thanks for your thoughts and thanks for watching!
@@OnlineExodontia so where should the bevel face before we inject?
@@landofmilkchillies5832 This is not a real significant consideration, but generally you are taught to insert with the bevel towards bone. As you are injecting, the plane of space that the bevel is in won't matter. Hope that helps. All the best!
@@OnlineExodontia ok... but it's always good to aspirate twice, in two directions ?(rotations/planes😅)
@@landofmilkchillies5832 That's essentially what I was trying to convey. All the best!
What if we give intravascular injection?
How to avoid intravascular injections even after following right technique?
Most times you won't cause any harm S D. Typically the patient will react to the epinephrine which causes a feeling of unease, increased heart rate and physiologic symptoms that don't match the patient's frame of mind. I've had it happen myself and it's an odd feeling. Your mind says you should be relaxed and at ease, yet your body is in fight or flight mode. The epinephrine thankfully is metabolized quickly and within a few minutes the patient should be doing much better. If you happen to miss your block significantly you can actually have some anesthetic enter the maxillary blood supply and you may notice blanching of the nose and blurred vision. This again is temporary, but you should be able to explain to your patient what is happening and reassure them that all will be ok. Hopefully that helps!
All the best!
@@OnlineExodontia thankyou so much Sir :)
@@OnlineExodontia i always get confused about aspiration. if we get blood in the cartridge do we hv to discard it ? or we inject the same cartridge into a new adjusted position??
@@fatimanadeem9588 Fatima, there is no need to discard the carpule if you get blood in it. That tells you you're intravascular and you need to reposition to ensure that you don't inject in the vessel and that your block / injection is successful. Does that help? All the best!
@@OnlineExodontia yess thank you so much ♥️
What kind of syringe is this?
Klaus thanks for watching...that syringe is a Miltex self-aspirating syringe. The barrel says 76-100 on it. It would be an oldie as it's been in the practice for many years. Hope that helps!
Could a patient possibly die from an accidental intravascular injection?
I don't have a solid answer for you here, but one would assume that a rapid injection of Lidocaine intravascularly could have an effect on the heart and in the right (or wrong) patient that could result in the formation of a potentially serious arrythmia which could then end up being fatal. I have not looked much into this topic so I don't know if there is much for literature on it, but it would be interesting to learn more. All the best!
That's why if you give lignocaine injection you will always look at the sryinge for any blood trace, if present than stop the procedure
Whoever disliked this must be a plumber or barber
interesting video. never considered a false negative aspiration. But for goodness sakes, stop touching the pointy end of the needle with your finger. made me cringe.
Haha will do! Thanks so much for your support in watching. All the best!
