How IV sedation benefited me

After having gone through one round of root canal treatment a coupla’ weeks ago – with another coming along three days from now – with IV sedation, I feel it’s beneficial to share how it went, and to let you guys know that there is such an option available.

Not many folks are aware that they can opt for IV sedation on top of local anaesthasia for minor surgical procedures, or for dental procedures. At least, not in Singapore. Based on some of the overseas forums I’ve read, IV sedation is more commonly practiced in the U.S. or U.K. Whereas, it is comparatively rarer here.

IV sedation involves the administration of a mixture anti-anxiety drugs and a sedative directly into the bloodstream via an IV line usually inserted at the back of the hand. The drugs put the patient into a state of light sleep, thus rendering him/her unaware of the procedure being carried out, but will not bring about a complete loss of unconsciousness. (Note: Not to be confused with General Anaesthasia.)

IV sedation helps a lot when dealing with procedural anxiety. I get generally apprehensive when it comes to medical procedures. That’s common, so does everyone else. However, nothing scares the shit out of me more than getting a dental procedure done.

I didn’t opt for IV sedation to cope with the fear though. I felt it was a better option for me because of my background heart condition. Heart condition plus procedural anxiety do not get along. The last thing I wanted was to end up in atrial tachycardia or explode into one of my epic heart flutter attacks in the midst of getting such a procedure done – which is why I chose to be sedated.

I spent about a week researching intensively on IV sedation and its pros and cons, and eventually decided that it was the best choice for me. My decision was met with a fair amount of resistance though, which held me back a little – but I stood firm with my decision and went ahead with it eventually.

I wasn’t at all surprised by the resistance expressed though. IV sedation is not as commonly practiced here, hence the reduced exposure to such cases (leading to the “huh?! Is it even necessary?!” mentality), and the general lack of awareness about it. One of my doctors even mixed up IV sedation with General Anaesthasia (the latter of which is much, much riskier).

General Anaesthasia induces deep unconsciousness and requires intensive monitoring of the patient’s vital signs. GA also takes much longer to recover from, with a higher risk of complications as it greatly suppresses the cardiovascular and respiratory systems. Patients under GA are always intensively monitored with the whole horde of menacing beeping machines you see in the Critical Care Units.

That is not to say that IV sedation is completely risk-free, though. There are very, very rare incidences of patients requiring artificial resuscitation as they were too deeply sedated. But every medical procedure has its fair share of risks. Even the root-canal procedure I went through had a risk level of complications far higher than the actual sedation itself (because mine unfortunately, also involved a deep infection of the bone).

IV sedation on the other hand, acts on the central nervous system which in turn, suppresses the cardiovascular and respiratory systems, but only slightly. The patient is unaware of what is going on due to the amnesia-inducing properties of the drug, but will not be completely unconscious which makes it much easier for the anaesthetist to manage.

I recovered really quickly post-sedation – “coming to” within 15 minutes after drug administration was stopped, and could even walk (albeit a little wobbly) almost immediately. I was monitored throughout the time I was “out” – but only with an pulse oxymeter and a blood pressure cuff … because that is only about what was needed.

It really helped me in the sense that it slowed down my usually rapid heart rate. And because I was “out”, there wasn’t any anxiety experienced that could potentially bring on a full fledged attack. The only minus about it was the involvement of an IV butterfly needle (which didn’t bode well with my general fear of needles). But better that, than to remain in a state of extreme stress for two hours with a potential atrial tachycardia attack lying in the background.

There are some inconveniences that accompany IV sedation though, such as the need to remain rested for the remaining day, and slight nausea. However, if you have background medical conditions that can potentially complicate a procedure, or severe procedural anxiety, IV sedation benefits more than anything else.

Of course, there are the sceptics that claim that “IV sedation is for pussies”, “You aren’t man enough if you need IV sedation”, or “IV sedation is only an easy way from anxiety.”

Forget all that, because all those are simply noise interfering with the patient’s personal decision based on his/her own background.

Ultimately, I believe it is about what’s best for you, and your comfort level.

And yeah, the whole purpose of this post is to let you guys know that when it comes to stuff like these, you have options to choose from. Don’t let fear stop you from undergoing any procedure you have to go for because recovery (or the prevention of further complications and infection) matters more than anything else.

And also to the folks with underlying medical conditions (like me) that could cause complications in conjunction with anxiety – look, choices!

Meanwhile, wish me the best of luck for this coming Thursday – it’s Round 2 of my Root Canal procedure (yes folks, with IV sedation) and I am going to have to contend with a swollen left cheek, various aches and pains, and potential light fever for two days after that. Whoopie.

[Written at 1.09 P.M. (07th June) Singapore time, 10.07 P.M. (06th June) Vancouver time.]

I was always under the impression that places in the USA and Canada will be a little more prudent when it comes to nut allergies because it is pretty rampant there. From what I heard, the rate of peanut allergies is highest among Westerners – I read about it on some article in a health magazine in Singapore about a year or two back.

It’s pretty cool to see nut allergy warnings on food boxes, labels and whatnot for once. I think it is a requirement here in view of the high nut allergy rates. T’was really helpful for people like me. (And helpful for the food companies too, so that they don’t get sued their pants off in the event an ‘accident’ happens.)

So I somewhat expected the same out of restaurants.

I was dining at a Chinese restaurant at Aberdeen (Richmond, Vancouver) this evening and my aunts ordered watercress soup (my favourite!) as one of the dishes. When the order was being taken, my uncle asked the waiter over and over again whether the soup contained nuts, which the latter denied. (For the strangest reason. He said nuts were expensive. o.O Huh and double huh?!)

So the food arrived and I slurped my soup happily, flashing my gleeful yum yum, watercress soup! grin at everyone in the vicinity, particularly my mum. She got suckered in by my grin and gave me some of her soup in response. Heh.

All things went well until I chanced upon this strange white solid … thing in my soup. It looked suspiciously like the edge of an almond, but I wasn’t sure. Plus, the waiter did say that the soup did not contain nuts. Could … it be some herb? Ginger? Garlic, perhaps? Sliced garlic sometimes looked like that.

My relatives tried tasting that little white solid mystery object for me, but no one could decipher what it was. By then, one of my aunts was beginning to look worried and told me to stop drinking the soup just in case.

Within a coupla’ minutes, my gleeful yum yum, watercress soup! grin had turned into a disappointed I have a bowl of untouchable watercress soup in front of me frown. (And at that time, I was already slightly itchy and could feel my throat swelling slightly – but I was trying to not think about it.)

My uncle summoned the waiter over.

The waiter studied the little white mystery object for a while before waving it aside.

“No, no, no! This is definitely not a nut or a peanut.”

I heaved a sigh of relief.

“It’s only an almond.”

A … WHAT?!?

At that moment, I wished I could have thrown up all the soup on the spot – because the hives were starting to appear in droves. I remained scratchy scratchy for the entire dinner. And the worst part? I chose the wrong day to change the bag I brought out because I had apparently, forgotten to transfer my medicine case over. :(

According to the waiter at the Chinese restaurant, they don’t consider almond as being part of the nut family. To them, an almond is like a fruit.

I’m fine now. Still a little itchy, but otherwise fine.

And I think the definition of what is a nut should have a worldwide standard.
