Creepy Things That Happen To The Body When Under Anesthesia

By Rio Dennis 1 year ago

1. Feeling Sick/Vomiting After Surgery

This is a very common side effect of anaesthesia, and it will occur when you come out of surgery. Your body will still be getting over the drowsiness of the drug, so it is more than likely that you will feel highly nauseous (and more than likely vomit).

2. Sore Throat

Similarly to nausea, you will experience a sore throat. This will be due to the lack of fluids you were able to consume prior to your procedure. Again, this is a very common side effect of anaesthetic, and it may take your body some time to recover.

3. Shivering

Shivering will often occur alongside the nausea and vomiting, as your body will be trying to maintain its temperature, whilst combatting any other side effects you may be experiencing. Shivering may also occur if you're highly anxious, or in any way panicked after your procedure.

4. Headache

Another common side effect is experiencing a headache. Again, this will occur due to the lack of fluids and food you've consumed prior to your procedure. You may also experience a headache if you are particularly sensitive to the fluorescent lights within a hospital.

5. Aches, pains and backache

Image Source: Reddit
You will find that your body is going to ache all over, especially where you've had your procedure. As anaesthetic works as a muscle relaxant, you will find that after surgery, your muscles will experience a deep, throbbing pain and will feel somewhat heavy.

6. Bruising and soreness

Image Source: Reddit
You may find excessive bruising on and around the injection area, especially if it was difficult for your anaesthetist to find a suitable vein for safe injection. This bruising may be much darker in colour, and will take your body longer to recover from.

7. Confusion and memory loss

Image Source: Reddit
Experiencing amnesia post-procedure is not as common, but it is still very likely. It often comes with feelings of disorientation, severe confusion and a general lack of awareness and understanding when it comes to your surroundings. This may also lead you to be unable to fully identify friends and family.

8. Chest infection

Image Source: Reddit
You're more likely to experience a chest infection, caused by anaesthetic, if you're a smoker and/or if you have an existing health condition e.g. asthma, bronchitis and general respiratory issues. If this is the case, you should notify medical personnel immediately.

9. Bladder problems

Image Source: Reddit
Following your procedure, you may experience problems with your bladder that cause you extreme pain and overall discomfort. It may not arise immediately, and could develop a few hours or days post-procedure. However, if this pain does not subside within a suitable time frame, you should contact a doctor.

10. Breathing difficulties

Image Source: Reddit
Breathing difficulties are likely to arise prior to your operation, especially once you enter the operating theatre and are being prepared for surgery. Difficulty breathing will likely happen if you are prone to panic attacks, high anxiety, feelings of claustrophobia and asthma.

11. Damage to your teeth, lips or tongue

Image Source: Reddit
This particular side effect is most common with the use of general anaesthetic. This is due to the use of a breathing tube, which is inserted into your mouth for the operation. Damage can occur during insertion and/or removal of this tube, so there isn't much you can do to prevent this.

12. An existing medical condition getting worse

Image Source: Reddit
This really only applies to medical conditions such as: asthma, bronchitis, COPD, diabetes and any conditions that affect your blood pressure. This is due to the overall effects that anaesthetic has on your breathing. Again, this is something that should be discussed with a medical professional.

13. Damage to your eyes

Image Source: Reddit
This side effect will usually develop post-procedure. Your body may have an adverse effect to the anaesthetic, and your body will try to tackle this in many ways. One of these ways may be via your eyes e.g. excessive weeping, eye infection, blurred vision and lack of vision (going blind).

14. Serious allergy to drugs

Image Source: Reddit
If you have an extensive history of allergies, especially when it comes to medication, it is highly likely that your body will react to any kind of anaesthetic. This can present itself via rashes, general irritation (and in some cases) anaphylactic shock.

15. Nerve damage

Image Source: Reddit
Nerve damage will likely occur during your procedure, and you will feel the effects of it during your recovery process. However, nerve damage can occur via the injection of anaesthetic, and will leave lasting damage to nerves within that area of your body.

16. Death

Image Source: Reddit
There have been cases where people have died whilst being under anaesthetic. It can happen prior to your procedure, during your procedure or shortly after your procedure. Although it is a rare side effect, it does happen, and you (and your loved ones) should be prepared for this.

17. Equipment failure

Equipment failure may happen during your procedure, whether it is the operating equipment, or the medical equipment ensuring you remain stable during your operation. Unfortunately, this is something out of your control, and can only be handled by a medical professional.

18. Awareness

Image Source: Reddit
Awareness of your surroundings, although rare, may still occur. Despite you being medically 'unconscious', your senses become heightened e.g. hearing equipment and medial personnel. This 'awareness' might be something similar to what a come patient may experience.

19. Loss of control over words

Image Source: Reddit
This will most likely occur prior to an operation and after waking up. As anaesthetic is a numbing drug, you will experience drowsiness and extreme muscle relaxation, which can lead to a loss of control when it comes to your speech. This side effect should usually subside within a day or so.

20. Extreme constipation

Image Source: Reddit
It is more than likely that you will experience this side effect during your recovery process. Again, this is your body's response to the lack of fluids and food you would have consumed prior to an operation. You can ask your doctor for medication (you can take orally) to help your bowel movements.

21. Random muscle twitching

Image Source: ALS Forums
As mentioned previously, anaesthetic (in any form) is a muscle relaxant. This means that following an operation, once the drug wears off, your muscles will ache, feel heavy and may be prone to random and erratic twitches. This side effect will usually take a couple of days to subside.

22. Intense dreams and hallucinations

Image Source: Reddit
Whilst under anaesthetic you may experience extremely vivid, and somewhat confusing, dreams/visions. When you wake up from an operation, the drowsiness you experience can develop into strange visual and audible hallucinations. This side effect, although worrying, is not harmful.

23. Waking up emotional or crying from anaesthesia

Image Source: Reddit
Following a procedure, you may wake up and suddenly become very emotional. This side effect will often occur alongside the feelings of disorientation, loss of control over your speech and possible hallucinations. Any strange/severe emotions should subside within a couple of hours.

24. Difficulty urinating

Image Source: Reddit
Another bodily function you will struggle with is urinating. Again, it's no surprise that this will be due to the lack of fluids you have consumed prior to your procedure. Don't panic, your ability to urinate should return within hours after an operation.

25. Haematoma

Image Source: Reddit
A haematoma is bleeding under the skin. This may occur in the injection area of the anaesthetic, or the surrounding operation area. It can spread and should be treated as soon as possible (after you have started your initial recovery process; to avoid any complications).

26. Pneumothorax

Image Source: Reddit
Pneumothorax occurs when an injection accidentally enters a lung, punctures it and causes the lung to collapse. Of course this is possible, if your anaesthetic injection occurs on your chest or near your rib cage. This will be out of your control, and dealt with accordingly by a doctor.

27. Waking up midway through surgery

Image Source: NBC News
Although this side effect is somewhat rare, there have been multiple cases of people waking up midway through surgery. This is a result of their anaesthetic dose being wrong for their weight, height and other contributing factors. For example, a heavy drinker and/or smoker would need a higher dosage of anaesthetic, compared to a standard person.

28. Paralysis

Paralysis is a rare side effect, but it occurs and it can have a lasting impact on you. You will more than likely experience temporary paralysis, however you may experience periodical or permanent paralysis long after your operation. Paralysis can be treated via suitable physical therapy treatment.

29. Itchiness

Image Source: Reddit
Itchiness will occur once the anaesthetic has fully worn off, and your body starts to recover. Your skin may become irritated and highly sensitive, which will cause you to scratch your skin and come up with rashes periodically. It is best if you avoid irritating the skin further by scratching.

30. Dry mouth

Image Source: Reddit
The side effect of a dry mouth will be caused by a lack of fluids consumed, and being under anaesthetic for a prolonged time. The best way to combat this will be to drink slowly but regularly following your procedure. You don't want to upset your body's internal recovery by drinking too much, too quickly.

31. What does anesthesia mean?

image source: reddit.com
Anesthesia means 'loss of sensation', though might think it means being put under in terms of loss of consciousness. Having anesthesia is all about stopping the sensation of pain so that you can undergo treatments and surgeries without being aware of how much they hurt.

32. The pain signals are road blocked

image source: reddit.com
It's weird to think that while under anesthesia, your body is having its pain signals completely blocked. So that means you are actually going through a lot of pain, your brain just isn't allowed to tell you that! The anesthesia blocks the pain signals from traveling along your nerves to your brain.

33. Anesthesia can be applied to specific areas of the body

image source: reddit.com
There isn't only one type of anesthesia, or one way of it working. There are anesthesias that will completely put you under, but some won't - and some can be applied only to a certain area of your body so that you won't feel pain or discomfort there, but you will normally everywhere else!

34. Your state of consciousness can be controlled

image source: reddit.com
As well as putting your life in someone else's hands, you'll be putting your consciousness in someone else's hands, too! General anesthesia is where whether you're awake or asleep can be controlled - and this is achieved through the drug traveling through your bloodstream to your brain.

35. Some anesthesias only numb and cut off the nerve

image source: reddit.com
For certain procedures, the anesthesia that is used will only numb certain areas of your body rather than control your consciousness. This one is a popular choice for people who might be at risk with general anesthesia. With this option, a certain nerve in a certain area of the body will be cut off from sending signals to the brain.

36. You could be injected in the fluid of your spine

image source: reddit.com
For spinal anesthesia specifically, you're going to lose all feeling from the waist down, due to the anesthetic being injected into the fluid of your spine at the base of it. The numbness will likely last a few hours, too, which will be weird if your treatment is only 10 minutes!

37. You might receive repeated dosage

image source: reddit.com
With anesthesia, it might also be the case that you need more and more of it so the state of your function is constantly controlled. This happens through an epidural, where the medical staff can then continue to add anesthesia to your body and numb your pain or put you to sleep when needed. As if once wasn't bad enough!

38. Your body is weirdly connected

image source: reddit.com
It just goes to show how sensitive your body's nerves are when you think that anesthesia doesn't have to be applied to the area in question. If you need treatment on your hand and wrist, for example, you could have anesthetic injected in the top of your arm and it will still have the same affect on your wrist nerves!

39. You could have sedation instead of anesthesia

image source: reddit.com
There may even be certain procedures where specific anesthesia isn't needed or available, then you can have sedation instead in order to lower the pain or discomfort you might feel from the procedure when your nerves aren't blocked off or numb. This can make you sleepy so it's easier to deal with!

40. You might be offered a distraction

image source: reddit.com
If you're undergoing a treatment that doesn't put you completely to sleep, you may be offered a distraction (like music or a film) while you're being worked on, even if anesthesia is used. This also goes to show how more things can hurt if we overly focus on them! And maybe how easily distracted our brains are...

41. Smokers may need more anesthesia

image source: reddit.com
This is apparently due to the fact that heavy smokers have 'irritated' airways because of the cigarettes they inhale, which can lead them to having an intolerance with the anesthetic breathing tubes. It's usual for heavy smokes to need more anesthesia as a result!

42. There are three main types of anesthesia you need to know about

image source: reddit.com
General anesthetic is what most people think of when anesthesia is mentioned, and this is the one where you're put into a nice little sleep and not aware of the anything! The other main two are local anesthesia, which is where a small area is number, and regional anesthesia, which stops pain and movement in a huge area of the body, but you're still conscious!

43. You usually won't feel pain if you do wake up

image source: reddit.com
One of the biggest fears people can have when it comes to anesthesia for surgery is that you're going to wake up - and as we mentioned, it can (and does) happen. But while you're imaging some painful ordeal where you can feel everything but you can't tell them, in reality you actually won't feel any pain even if you do wake up... probably.

44. And it'll be brief!

image source: reddit.com
And if you do wake up, it won't be hours and hours of a long surgery that you'll be 100% aware of - the likelihood is that if you do wake up, it'll be a very very brief moment of consciousness before you drift off again, which is also why it's unlikely you'll feel any pain.

45. Being overweight can increase risks

image source: reddit.com
If you're really overweight, it can make a hard time for anesthesiologists. As we know, the amount of anesthesia to give to successfully knock you out or numb a certain area will be based on your weight and body factors, and this can be harder to measure if you're packing extra pounds!

46. Have you heard the myth about redheads?

image source: reddit.com
There is actually a widely held myth - and it definitely is a myth because doctors have debunked it - that redheads would actually need more anesthesia than any other hair color because redheads are believed to have a gene called melanocortin-1 which can make them less susceptible to anesthesia! So if you're a redhead and you've been worrying - don't!

47. Aromatherapy could actually help you after you wake up

image source: reddit.com
You might be surprised that a home remedy like aromatherapy can actually be successfully paired with heavy medical treatment, but it's been shown that certain smells can help to stop the nausea and vomiting that can come as a result of anesthetic - ginger and lavender oil in particular.

48. Memory loss could last for days

image source: reddit.com
We've mentioned that your memory can be all hazy when you've woken up from anesthesia, but did you know it can actually last for a long time after? Not only could it last for days, but in some cases it could even last for months! That's a hefty time to deal with feeling a little fuzzy.

49. Exposure to anesthesia could reveal hidden problems....

image source: reddit.com
Speaking of memory loss - it can actually be an issue for people who are over 70 and already struggling with memory loss conditions they might not have officially known about. It's been suggested that anesthesia can be such a big trigger for memory loss that it can then unmask memory loss conditions patients over 70 already had!

50. Even doctors are still learning more about anesthesia!

image source: reddit.com
As we know, even doctors in the medical field are still learning about new and improved ways of doing things - and anesthesia is no different. The good news is, that the more doctors learn about how anesthesia works, the better they can perfect it (and make it less likely you have to worry about waking up during surgery!).
