General anaesthetic for anal surgery

What this experience covers

Having a general anaesthetic for any procedure creates anxiety, and anal surgery adds its own layer of concern. This experience covers what people describe about the general anaesthesia aspect — the preparation, the experience of going under and waking up, and the first hours afterwards.

The pattern

Before the anaesthetic

People describe the hours before going under as dominated by a specific anxiety: not about the procedure itself (which they will not experience), but about the anaesthetic and waking up afterwards.

Common pre-anaesthetic experiences:

  • Fasting from the night before — typically no food for six hours, no water for two hours
  • Changing into a hospital gown
  • Meeting the anaesthetist for a pre-assessment — discussing medical history, allergies, and any concerns
  • Having a cannula (IV line) placed in the hand or arm
  • Waiting — often the hardest part

Going under

People describe the actual process as quick and uneventful:

  • Walking or being wheeled into the operating theatre
  • The anaesthetist connecting medications through the IV
  • Being asked to count backwards or take deep breaths through a mask
  • A brief sensation of lightheadedness or warmth
  • Then nothing — people describe it as “blinking” and waking up in recovery

Waking up

The most commonly described experience of waking from general anaesthesia:

  • Gradual awareness — voices, lights, a sense of time having passed
  • Confusion about where they are — this passes quickly
  • A nurse nearby monitoring and reassuring
  • Feeling groggy, sleepy, and slightly disoriented
  • Sometimes nausea — this is common and manageable with medication
  • Gradually becoming more alert over 30 to 60 minutes

The first hours

  • Pain at the surgical site is often managed proactively — pain relief given before full wakefulness
  • Throat may be slightly sore if a breathing tube was used
  • Some people feel cold and are given warmed blankets
  • Drinking water is usually offered once alert enough
  • Being monitored until the anaesthetic effects have worn off sufficiently for discharge

What people wish they had known

That the anaesthetic is usually the easiest part of the whole process. People describe spending more time worrying about it than it warranted. The procedure itself passes without awareness, and the recovery from anaesthesia is typically straightforward.

See all the signs

For this topic, get medical advice if you notice:

  • Severe or worsening pain
  • Heavy bleeding
  • Fever
  • Black stools
  • Fainting or dizziness
  • Pus or unusual discharge
  • Inability to pass stool or gas
  • Unexplained weight loss

Recording how you feel is not the same as being checked. These are the signs that need a doctor’s attention.

Call 911 or go to the emergency room now if you have:

  • bleeding that will not stop, a lot of blood (the toilet water turns red, or you pass large clots), or any bleeding with feeling faint or dizzy
  • fainting, a racing heart or trouble breathing
  • confusion or slurred speech, extreme shivering, no urine in a day, or blotchy skin
  • sudden severe belly pain, or a swollen, hard belly with vomiting or not passing stool or gas
  • you cannot pass urine at all, or your bladder feels full and painful and you can’t empty it
  • redness, swelling or severe pain spreading quickly around your anus, genitals or groin, especially with a fever or feeling very ill
  • a fever with a painful swelling near your anus if you have diabetes or a weakened immune system (for example, from chemotherapy or transplant medicines)
  • black, tarry stools

Call your doctor or go to urgent care today (or the ER if you can’t be seen today) if you have:

  • a temperature of 100.4°F (38°C) or higher, chills, vomiting, or feeling generally unwell
  • pain that is getting worse over days, or severe pain that stops you sitting or sleeping
  • a hot, swollen or very tender lump near your anus or at the top of the crease between your buttocks, or foul-smelling discharge
  • trouble urinating
  • bleeding that is getting heavier or more frequent, or blood mixed into your stool
  • feeling much more tired than usual, looking pale, or getting out of breath more easily than you used to
  • not passing stool for several days, or new belly pain

Make an appointment with your doctor if:

  • you have never had these symptoms checked by a doctor or nurse — whatever your age
  • you have had rectal bleeding for more than 3 weeks
  • your bowel movements have been looser, thinner or more frequent than usual for 3 weeks or more, or you have lost weight without trying
  • symptoms have not settled after a week or so, or keep coming back
  • you notice a new lump near your anus, between your buttocks or in your belly, or an itch or discharge that does not clear
  • you have new leakage or trouble controlling your bowels
  • you are 45 or over, or have a family history of bowel cancer or inflammatory bowel disease, and any of these symptoms are new for you

If you are unsure, it is always reasonable to ask. If things feel overwhelming, call or text 988 (Suicide & Crisis Lifeline) or chat at 988lifeline.org, any time. If you don’t feel safe, call 911.
