What's the difference in anesthesia used for colonoscopy and that used in c section? If the patient was put to sleep for c section.

What's the difference in anesthesia used for colonoscopy and that used in c section? If the patient was put to sleep for c section.

Sedation vs.: anesthesia. A person is only sedated for colonoscopy and does not lose consciousness as is the case with anesthesia. Anesthesia can be used for colonoscopy, though it is not needed. C-section requires anesthesia and cannot be done by sedation alone. ...Read more

Is it normal to sleep all day the day after getting general anesthia for a colonoscopy and upper endoscopy?

Is it normal to sleep all day the day after getting general anesthia for a colonoscopy and upper endoscopy?

Depends. . .: Different drugs used to achieve anesthesia have different half-lives which translates into different lengths of time for their effects to dissipate. Depending on the amount that was used to achieve, the sedation effect may linger for awhile. Anesthesia drugs tend to absorb into the fat tissues of the body and may be released slowly afterwards producing some lingering somnolence. ...Read more

Does it take a while to get over the effects of twilight anesthesia for a colonoscopy?

Depends on type: If the anesthetic is given by an anesthesiologist they would usually use a very short acting anesthetic agent. If the sedation is done by the GI doctor they tend to use a longer lasting agent. In either case you should be clear headed after a few hours. ...Read more

Discuss with doc: Many fears can be addressed if you talk to your healthcare professional. Egd ; colonoscopies are typically done only with sedation, and there is no general anesthesia. If you are really concerned, or if your md thinks you need general anesthesia, you will have an anesthesiologist there. ...Read more

I take one 8mg Suboxone strip daily. Will this interfere with my colonoscopy scheduled in four days. Will the anesthesia be effective?

Should be fine.: What I wouldn't do is stop the Suboxone abruptly, as that could cause more troubles. Just let the anesthesiologist know that you're on that medication so that anesthetics may be adjusted accordingly. ...Read more

On average how long does a colonoscopy and endoscopy done at the same time take? Will the sedation cause funny behavior after like anesthesia does?

On average how long does a colonoscopy and endoscopy done at the same time take? Will the sedation cause funny behavior after like anesthesia does?

Short sedation: EGD(upper endoscopy) can be as short as 5 minutes, with biposies most of them accopmlished in ~15 min. Colonoscopy takes longer, most fit in the timeframe of 20-40 minutes. The sedation used for the procedure is quite deep usually and approaches/equals Total Intravenous Anesthesia, TIVA. Due to nature of the drug(s) used the recovery may vary but usually is pretty fast and free of side effects. ...Read more

Can u have a colonoscopy done with something other than general anesthesia? Such as conscious sedation?

Yes: Intravenous sedation can be very effective in assuring comfort and sedation during a colonoscopy. General anesthesia, though used commonly because it can be "eliminated" so quickly from one's body, isn't mandatory. Discuss with your endoscopist or anesthesiologist! no worries! ...Read more

Yesterday I had colonoscopy with anesthesia (passed out for the whole procedure) and today my lungs hurt. Why, what's the connection?

R/O COMPLICATION: Often times Propofol is used for anesthesia it is very potent. Rarely when you are recovery from anesthesia, fluid may get into the lungs. This is referred as aspiration. I recommend following up with your GI doctor. If symptoms worsen acutely or fever develops, get immediate evaluation and X-ray to rule out aspiration Pneumonia. ...Read more

I'm Having a steroid shot and they give me anesthesia and then in 2 weeks having a colonoscopy where I'll have anesthesia. Is that safe?

I'm Having a steroid shot and they give me anesthesia and then in 2 weeks having a colonoscopy where I'll have anesthesia. Is that safe?

Yes: It may not even be the same type of anesthesia. Often local numbing with an injection is all that is needed when local steroids are administered. With a colonoscopy, usually drugs are administered through a IV line resulting in what is called conscious sedation. A 2 week gap is reassuring.Even when surgeries have to be performed "back to back" in emergency situations, all can be done safely:) ...Read more

I am scheduled for a colonoscopy. Is a facility able to enforce anesthesia if I do not want to take it. They use propofol and i don't want it.

I am scheduled for a colonoscopy. Is a facility able to enforce anesthesia if I do not want to take it.  They use propofol and i don't want it.

Informed consent: Nothing should be done before explaining pros and cons and obtaining your permission. Propofol is not the only choice, although it is probably best drug for it today. One can undergo colonoscopy without any anesthesia, the experience is likely to be quite unpleasant and stressful and conditions for the doctor performing it suboptimal, so i would invite you to address all your concerns beforehand. ...Read more

Doc could not complete colonoscopy due to severe angulation in sigmoid and thickened colon  had anesthesia.  Any future problem?What next?

Sounds complicated: Given your history, it sounds very complicated! recovering from a perforated colon, a colonoscopy is good to help get answers. There are very advanced docs who do colonoscopies with special equipment. It might be worth getting a referral to someone with more specialized training and tools who can try to navigate. ...Read more

My doctor wants to use general anesthesia for an endoscopy. Why would I need to be completely out? He just did sedation for my colonoscopy.

My doctor wants to use general anesthesia for an endoscopy. Why would I need to be completely out? He just did sedation for my colonoscopy.

This is a good: question for you to ask him. Typically, upper/lower endoscopy is performed with conscious sedation, presumably what you had previously. Perhaps he observed you to have responses to stimuli indicating you might be experiencing pain during the colonoscopy procedure. Maybe he is concerned about your breathing or cardiac function..typical issues suggesting general anesthesia. Only he can answer. ...Read more

I have a lot of ptsd/anxiety issues and I have asperger's syndrome. I need a colonoscopy. Is that something that can be done in the or and under general anesthesia?

Talk with drs: Have a pre procedural visit with your doctor explaining your conditions. All medical procedures presume healthy mental status and mood. If you are at all unsure or uncertain, most doctors will make time to talk with you in detail about the procedure or collaborate with other doctors (psychologists and psychiatrists) to make the procedure clear and less anxiety provoking to the patient. ...Read more

They are both safe: These drugs can be used as sedation OR general anesthesia. It is determined by the amounts given and the patient's physiologic response. Both general anesthesia and conscious sedation are safe in the hands of a competent anesthesia provider who takes in account the patient's medical history, medications and physical condition. ...Read more
