[Health Column] How is a Sedation Endoscopy Proceeding? Fasting Before the Examination and Post-Examination Precautions

 

hello, Director Jo Hwan-jun of Eunpyeong Central Internal Medicine It is. 🩺
As a subspecialist in gastrointestinal endoscopy, I primarily perform upper and lower gastrointestinal endoscopy and provide consultations on health checkup results.

 

When facing an endoscopy, concerns such as "Will it be too difficult?" or "If I undergo sedation, will I really be completely unaware of anything?" may arise before the examination itself. If it is your first time, you may also wonder when you need to start fasting, what to do with your usual medications, and whether you can drive or work immediately after the procedure.

 

Due to the commonly used term 'sedation endoscopy,' it is easy to assume that the examination is performed while completely asleep, but the actual level of sedation varies from person to person. The preparation process and recovery time may also differ depending on the type of examination, the medications used, and the individual's health condition.

 

In this article, we take a detailed look at the meaning of sedation endoscopy and the preparations before and after the examination.

1️⃣ What kind of examination is a sedation endoscopy?

Sleep endoscopy A method of conducting an endoscopy while using sedatives to reduce anxiety and discomfort. no see.

 

While the term 'sedation endoscopy' is familiar in everyday life, medically, Sedation endoscopy or Conscious sedation endoscopy The term is used. It is conceptually different from general anesthesia, which completely eliminates consciousness, and the degree of sedation may vary depending on the drugs used, the dosage, and the individual's response.

 

Therefore, not everyone falls asleep completely during the examination. Some people remember parts of the process, and the degree of sedation can vary even when using the same medication.

 

The Korean Society of Gastrointestinal Endoscopy's guidebook also treats sedation endoscopy as a single process, ranging from pre-examination patient evaluation to monitoring during sedation and post-examination recovery.

 

💡 core
Sleep endoscopy is not simply an 'examination received comfortably while asleep,' but rather, as sedatives are used A method that considers pre-examination preparation, observation during the examination, and post-examination recovery together. It is best to understand it as such.

 

2️⃣ Is a sedated endoscopy really performed while the patient is asleep?

Even if you undergo a sleep endoscopy, not everyone falls asleep to the same depth, and Individual differences exist in the degree of sedation and memory of the examination process. There is.

 

While the use of sedatives can reduce tension and induce drowsiness, patients may still react to medical staff during the examination. Conversely, individuals sensitive to sedatives may experience a deeper level of sedation than expected.

 

Age, health condition, medications being taken, and previous experience with sedatives can also affect the degree of sedation.

 

Therefore, when choosing a sedated endoscopy, it is important to consider your current health condition as well as the benefits and precautions associated with the use of sedatives, rather than simply viewing it as a "comfortable method to fall asleep."

 

3️⃣ Why is fasting necessary before a sedated endoscopy?

📌 It is a good idea to check your fasting time, any medications you are taking, your health condition, and your return home route the day before the examination.

 

Fasting before a sleep endoscopy To facilitate endoscopic observation and reduce the risk of gastric contents refluxing into the airway while sedated It is important.

 

In particular, during a gastroscopy, it can be difficult to observe the mucosa if food remains in the stomach. Since protective responses such as swallowing or coughing may be reduced compared to normal when sedatives are used, it is also important to check whether food or beverages have been consumed before the examination.

 

However, it is not appropriate to strictly apply a single fasting time guideline found online to all examinations. This is because instructions may vary depending on the examination time, type of examination, and individual health condition. If you are scheduled for a gastroscopy... Check the purpose of the examination and fasting method separately. You need to do it.

 

4️⃣ How do preparations for a gastroscopy and a colonoscopy differ?

📌 Fasting is the key to preparation for a gastroscopy, while dietary control and bowel cleansing are key to preparation for a colonoscopy.

 

While fasting is primarily important for a gastroscopy, for a colonoscopy, dietary control and thoroughly emptying the bowels Bowel cleansing There is a difference in the preparation method in that the process is also required.

 

Since a gastroscopy examines the esophagus, stomach, and part of the duodenum, it is important to prepare by ensuring that no food remains in the stomach. You must check the instructions regarding how long you are allowed to consume food and water depending on the examination time.

 

On the other hand, a colonoscopy requires the removal of any remaining stool from the intestines to adequately observe the colon mucosa. This may require adjusting your diet for a certain period prior to the examination and taking prescribed bowel cleansing agents.

 

The Korea Disease Control and Prevention Agency's guidelines for colonoscopy also explain that the state of bowel preparation is a crucial factor in adequately observing the colon mucosa. However, the type of bowel cleansing agent, the timing of administration, and the method of restricting food intake prior to the examination may vary depending on the examination schedule and the medication used.

 

5️⃣ Is a sedated endoscopy more accurate than a regular endoscopy?

Just because sedatives are used The accuracy of endoscopic examinations does not automatically increase.

 

The primary purpose of sedation endoscopy is to reduce tension and discomfort experienced during the examination process. It is difficult to simply compare lesion detection rates or examination accuracy based solely on whether sedation is applied.

 

Various factors, such as pre-examination preparation, the examination site, the condition of the mucosa, and the examination process, can influence the actual endoscopic observation. In particular, fasting is a crucial preparatory factor for sufficient observation during gastroscopy, while bowel cleansing is an important factor during colonoscopy.

 

Therefore, rather than viewing sedated endoscopy and non-sedated endoscopy as always being superior Considering the purpose of the examination, the individual's condition, concerns about discomfort, and the benefits and risks associated with the use of sedatives together. This is important.

 

6️⃣ What should I do if I am taking any medication?

Before the endoscopy, check the medications you are currently taking, Do not stop taking the medication or change the dosage without guidance from a medical professional. This is important.

 

In particular, if you are taking medications related to bleeding, such as antiplatelet agents or anticoagulants, it is necessary to check how to take them before the examination, considering the possibility of a biopsy or polyp removal. The Korea Disease Control and Prevention Agency's guidelines for colonoscopy also advise against arbitrarily stopping antiplatelet or anticoagulant medications and recommend consulting with medical staff regarding their use before the examination.

 

Even when using diabetes medication or insulin, a different dosage regimen than usual may be required due to fasting. Instructions for high blood pressure medication may also vary depending on the type of drug and your health condition.

 

 

7️⃣ Can I drive immediately after a sedated endoscopy?

📌 Please prepare your way home in advance so that you do not drive yourself on the day of the examination.

 

Even if you feel fully awake on the outside after an endoscopy using sedatives It is recommended to avoid driving on the day of the examination, as judgment and reaction speed may not fully recover.

 

Once the examination is complete, you will wait in the recovery room for the effects of the sedative to wear off while monitoring your condition, including consciousness, breathing, and blood pressure. The time required for recovery may vary depending on the medication used and the individual's response.

 

It is advisable to arrange your return home in advance so that you do not have to drive yourself on the day of the examination. It is also recommended to avoid schedules that require concentration and quick judgment, such as important contracts, decision-making, or operating dangerous machinery.

 

The timing for resuming meals or usual medications may vary depending on whether a gastroscopy or colonoscopy was performed, and whether procedures such as a biopsy or polyp removal were carried out. It is important to review the instructions provided after the examination.

 

8️⃣ What should I check before and after a sedated endoscopy?

The following is not a criterion for you to decide for yourself whether or not you are eligible for a sedated endoscopy, Reference items for organizing necessary information before and after the examination no see.

 

 

Just because various criteria have been checked does not mean that a sedated endoscopy is suitable for everyone. The examination method can be determined by considering the purpose of the examination, current health status, and the benefits and risks associated with the use of sedatives.
