What happens if you stop breathing during anesthesia?

If you stop breathing during anesthesia (apnea), your anesthesiologist immediately intervenes with a breathing tube (endotracheal tube) or mask to manually ventilate you with oxygen, preventing serious brain damage (hypoxia/anoxia) from oxygen deprivation, which can cause cognitive issues, memory loss, or worse; this is usually managed quickly with monitoring and interventions like ventilators or reversal agents, but serious outcomes can happen if it's not handled fast enough, especially in high-risk patients like those with sleep apnea.

Is it normal to stop breathing under anesthesia?

Apnea during anesthesia has several etiologies, including anesthetic agents themselves, as well as opiates, barbiturates, or benzodiazepines, and hypocarbia-induced respiratory depression.

What are the chances of not waking up from anesthesia?

The chance of not waking up from anesthesia (meaning death or severe harm) is extremely low, often cited as less than 1 in 100,000 for healthy individuals, but it's more common to experience a slow or "delayed" awakening, where you wake up but take longer than expected, due to factors like drug effects, surgery length, age, or health conditions. While true "anesthesia awareness" (waking up during surgery) is also rare (1-2 in 1,000 cases), it's a different phenomenon from not waking up at all, and it usually involves awareness without pain, but can be distressing. Modern anesthesia and monitoring make it very safe, but your overall health and the surgery's complexity play a big role. 

Why can't you breathe during general anesthesia?

During a general anaesthetic, the muscles in your body relax, including those around your throat and chest. This can lead to your airway becoming blocked or your breathing becoming restricted.

What is the most common complication of general anesthesia?

The most common complication of general anesthesia is postoperative nausea and vomiting (PONV), often accompanied by a sore throat, especially from the breathing tube (endotracheal tube) used during surgery, with other mild issues like sleepiness, dizziness, or muscle aches also frequent. While severe issues like malignant hyperthermia or major organ damage are very rare, common discomforts are usually temporary and manageable.
 

3 things you DON'T KNOW happen to YOUR BODY under anesthesia (and HACKS TO FIX in 2023!)

Who should not go under general anesthesia?

In addition to the elderly, people who have conditions such as heart disease (especially congestive heart failure), Parkinson's disease, or Alzheimer's disease, or who have had a stroke before are also more at risk. It's important to tell the anesthesiologist if you have any of these conditions.

What are the big 5 anesthesia complications?

Five complications that commonly occur during anesthesia include hypotension, hypothermia, abnormal heart rate (eg, bradyarrhythmias, tachyarrhythmias), hypoventilation, and difficult recovery (eg, prolonged duration, dysphoria, pain).

Do they stop you breathing when putting you under for operation?

During the procedure

Sometimes you may be given a gas that you breathe from a mask. Children may prefer to go to sleep with a mask. Once you're asleep, the anesthesiologist or CRNA may insert a flexible, plastic breathing tube into your mouth and down your windpipe. The tube ensures that you get enough oxygen.

Can I breathe on my own with general anesthesia?

No, under general anesthesia, your muscles, including those for breathing, are relaxed or temporarily paralyzed, so you generally cannot breathe effectively on your own; an anesthesiologist assists or controls your breathing with devices like breathing tubes and ventilators to ensure oxygenation. While some situations allow for spontaneous breathing support, the primary goal is airway control, usually via an endotracheal tube or laryngeal mask airway (LMA) connected to a ventilator. 

What is the 2 4 6 rule for anesthesia?

The 2-4-6 rule for anesthesia is a guideline for preoperative fasting, indicating how long patients should abstain from food and drink before surgery to prevent aspiration (inhaling stomach contents): 2 hours for clear liquids, 4 hours for breast milk, and 6 hours for formula or light meals, with heavier meals requiring longer (often 8+). This evidence-based rule, established by the American Society of Anesthesiologists (ASA), replaces older "NPO after midnight" mandates, allowing for shorter, safer fasting times for most healthy patients. 

Is dying under anesthesia rare?

The risk of dying in the operating theatre under anaesthetic is extremely small. For a healthy person having planned surgery, around 1 person may die for every 100,000 general anaesthetics given. Brain damage as a result of having an anaesthetic is so rare that the risk has not been put into numbers.

How do anesthesiologists know you're asleep?

Anesthesiologists know you're "asleep" (unconscious) by combining continuous monitoring of vital signs (heart rate, blood pressure, oxygen) with specialized brain activity monitors (like EEG/BIS monitors) that track electrical signals, ensuring brain activity aligns with unconsciousness, and checking for lack of movement or response, especially when muscle relaxants are used, as general anesthesia isn't natural sleep but a drug-induced coma. They use these tools to confirm you're not experiencing awareness during surgery. 

Does your heart stop during general anesthesia?

No, your heart doesn't normally stop under general anesthesia; anesthesiologists work to keep it stable, but cardiac arrest is a rare complication, usually due to underlying conditions, blood loss, or surgical stress, requiring immediate intervention like CPR and medications to restart it. Anesthesia slows metabolism and can affect heart rate, but the goal is stable heart function, not stopping it, with serious events like cardiac arrest happening in a small fraction of cases, often linked to other factors.
 

Does anesthesia shut down your lungs?

General anesthesia and mechanical ventilation impair pulmonary function, even in normal individuals, and result in decreased oxygenation in the postanesthesia period. They also cause a reduction in functional residual capacity of up to 50% of the preanesthesia value.

What is anesthesia where you breathe on your own?

What Is Monitored Anesthesia Care (MAC)? MAC anesthesia is accomplished by giving you medications that help you relax during a minor procedure. This is different from general anesthesia because you remain breathing on your own during the procedure and do not have a breathing tube.

What does going under anesthesia feel like?

Going under general anesthesia feels like drifting into a deep sleep, where you quickly become unconscious, feel no pain, and have no memory of the surgery, often feeling like only a moment passed before waking up groggy in recovery. You might feel dizzy or hear sounds differently as you drift off, while waking up can bring grogginess, disorientation, chills, or emotional confusion, all normal parts of the recovery process.
 

How many times is it safe to go under anesthesia?

In general, anesthesia is considered safe, and most people can undergo multiple procedures with anesthesia without any long-term adverse effects. However, each time you undergo anesthesia, there is a small risk of side effects or complications such as nausea, vomiting, sore throat, headache, or confusion.

What type of anesthesia is safest?

The safest type of anesthesia is generally local anesthesia, which numbs a small, specific area and lets you stay awake, having the fewest side effects and fastest recovery. Regional anesthesia (like spinal/epidural) is also very safe, blocking larger areas. While general anesthesia (total unconsciousness) carries more risks, it's often necessary for complex surgeries and is extremely safe due to modern monitoring and an expert team, with risks more tied to procedure/health than the anesthetic itself.
 

What is the most serious complication of anesthesia?

Other serious complications, such as nerve injury, awareness, malignant hyperthermia, or death can even occur. Fortunately, the above complications are relatively or exceedingly rare. Aspiration pneumonia (inhaling vomit into the lungs) can represent a most serious complication of anesthesia.

How do they wake you up from general anesthesia?

They wake you up from general anesthesia by gradually reducing or stopping the anesthetic medications as surgery ends, allowing your body to clear them, while the anesthesiologist monitors your vital signs and breathing, potentially giving reversal drugs for muscle relaxants, and removing the breathing tube (if used) once you're stable, leading to a slow recovery of consciousness in the recovery room.
 

Can a patient breathe during general anesthesia?

No, you cannot breathe on your own under general anesthesia because the medications paralyze your breathing muscles, so an anesthesiologist uses a breathing tube (endotracheal tube) or another device, like an LMA, to control your breathing and deliver oxygen and anesthetic gases via a ventilator. A dedicated anesthesia team member constantly monitors your vitals and breathing throughout the entire surgery to ensure safety.
 

What is the most common critical incident in anesthesia?

Spinal anesthesia was involved in 50% of the cases, and most incidents (77.3%) occurred during the anesthetic procedure. Cardiovascular issues (18.2%) such as bradycardia and hypotension, airway complications (13.6%), and drug-related errors (13.6%) were among the common types of incidents.

How long does general anesthesia stay in your system?

General anesthesia generally leaves your system within 24 hours, but grogginess and lingering effects can last longer, often 24-48 hours, with some drugs taking up to a week to fully clear, depending on the type, dosage, your health, and surgery length, so you must arrange a ride and rest for at least a day. 

How risky is general anesthesia?

General anesthesia is very safe for most people, with severe complications being rare, but risks exist, ranging from common minor side effects (nausea, sore throat) to rare serious ones (allergic reaction, heart/lung issues, awareness during surgery, stroke). Risks increase with age or underlying health conditions (heart, lung, brain disease), but advanced monitoring and protocols make it much safer now, with most danger coming from the surgery or patient health, not the anesthesia itself.
