Anesthesia can you feel pain

Muscle aches — The medications used to relax your muscles so a breathing tube can be inserted can cause soreness. Itching — This is a common side effect of narcotics, one type of pain medication sometimes used with general anesthesia. Chills and shivering hypothermia — This occurs in up to half of patients as they regain consciousness after surgery, and it might be related to body temperature. Rarely, general anesthesia can cause more serious complications, including: Postoperative delirium or cognitive dysfunction — In some cases, confusion and memory loss can last longer than a few hours or days.

A condition called postoperative cognitive dysfunction can result in long-term memory and learning problems in certain patients. People who have had a stroke in the past are also more at risk. Malignant hyperthermia — Some people inherit this serious, potentially deadly reaction to anesthesia that can occur during surgery, causing a quick fever and muscle contractions.

If you or a family member has ever had heat stroke or suffered from malignant hyperthermia during a previous surgery, be sure to tell the physician anesthesiologist. Headache — This can occur a few days after the procedure if some spinal fluid leaks out when regional anesthetic is delivered through the spine, as in an epidural or spinal block for childbirth.

Minor back pain — Soreness can happen at the site where the needle was inserted into the back. Difficulty urinating — If you were numbed from the waist down, it may be difficult to urinate for a little while after the procedure. Hematoma — Bleeding beneath the skin can occur where the anesthesia was injected.

It did not occur to her to ask. Things can go wrong. Equipment can fail — a faulty monitor, a leaking tube. Certain operations — caesareans, heart and trauma surgery — require relatively light anaesthetics, and there the risk is increased as much as tenfold.

One study in the s found that close to half of those interviewed after trauma surgery remembered parts of the operation, although these days, with better drugs and monitoring, the figure for high-risk surgery is generally estimated at closer to one in Certain types of anaesthetics those delivered into your bloodstream, rather than those you inhale raise the risk if used alone. Some people may simply have a genetic predisposition to awareness.

Human error plays a part. But even without all this, anaesthesia remains an inexact science. An amount that will put one robust young man out cold will leave another still chatting to surgeons. Last time I searched, the paper had been adjusted slightly to acknowledge recent advances in brain monitoring, but the message remained the same: just because a person appears to be unconscious, it does not mean they are.

It really is art more than science … We try to give the right doses of the right drugs and hope the patient is unconscious. The death rate from general anaesthesia has dropped in the past 30 years, from about one in 20, to one or two in ,; and the incidence of awareness from one or two cases per to one or two per 1, I t is perhaps the most brilliant and baffling gift of modern medicine: the disappearing act that enables doctors and dentists to carry out surgery and other procedures that would otherwise be impossibly, often fatally, painful.

The term anaesthesia was appropriated from the Greek by New England physician and poet Oliver Wendell Holmes in , to describe the effect of the drug ether following its first successful public demonstration in surgery. Anaesthetise: to render insensible. These days there are other sorts of anaesthetics that can numb a tooth or a torso, simply or unsimply by switching off the nerves in the relevant part of the body.

But the most widespread and intriguing application of this skill is what is now known as general anaesthesia. In general anaesthesia, it is not the nerve endings that are switched off, but your brain — or, at least, parts of it.

These, it seems, include the connections that somehow enable the operation of our sense of self, or loosely consciousness, as well as the parts of the brain responsible for processing messages from the nerves telling us we are in pain: the neurological equivalent of shooting the messenger. Which is, of course, a good thing. I am one of the hundreds of millions of humans alive today who have undergone a general anaesthetic.

It is an experience now so common as to be mundane. Anaesthesia has become a remarkably safe endeavour: less an event than a short and unremarkable hiatus. The fact that this hiatus has been possible for fewer than two of the 2, or so centuries of human history; the fact that only since then have we been able to routinely undergo such violent bodily assaults and survive; the fact that anaesthetics themselves are potent and sometimes unpredictable drugs — all this seems to have been largely forgotten.

Anaesthesia has freed surgeons to saw like carpenters through the bony fortress of the ribs. It has made it possible for a doctor to hold in her hand a steadily beating heart. It is a powerful gift. But what exactly is it? Part of the difficulty in talking about anaesthesia is that any discussion veers almost immediately on to the mystery of consciousness. And despite a renewed focus in recent decades, scientists cannot yet even agree on the terms of that debate, let alone settle it.

Is consciousness one state or many? Can it be wholly explained in terms of specific brain regions and processes, or is it something more? Is it even a mystery?

Or just an unsolved puzzle? And in either case, can any single explanation account for a spectrum of experience that includes both sentience what it feels like to experience sound, sensation, colour and self-awareness what it feels like to be me — the subjective certainty of my own existence? But stray off the bitumen, and it is surprising how quickly pharmacology and neurology give way to philosophy: if a scalpel cuts into an unconscious body, can it still cause pain?

And then ethics: if, under anaesthesia, you feel pain but forget it almost in the moment, does it matter? Greg Deacon, a former head of the Australian Society of Anaesthetists, told me about a patient who was waiting to have open heart surgery. Deacon had been preparing to anaesthetise him, he said, when the man went into cardiac arrest. If it should happen to you, be sure to describe your experience to your physician anesthesiologist after your surgery. Some patients benefit from counseling after surgery to help cope with feelings of confusion and stress.

Before your surgery, your physician anesthesiologist will meet with you to learn about any health conditions you may have as well as your previous experiences with anesthesia.

To reduce your risk of experiencing awareness during general anesthesia, it is important to tell your physician anesthesiologist as much information about your health as possible, including the following:. Physician anesthesiologists are the most highly skilled medical experts in anesthesia care, pain management, and critical care medicine with the education and training that can mean the difference between life and death.

Anesthesia today is safer than it has ever been due to advances in technology and pharmacology, as well as more stringent practice standards and educational requirements for anesthesia providers. A report by the Institute of Medicine titled "To Err is Human" indicated that anesthesia is nearly 50 times safer than it was in the early s.

These advanced practice nurses are anesthesia professionals who safely administer approximately 43 million anesthetics each year. CRNAs provide anesthesia care for all types of surgeries and other procedures, including open heart and transplants.

CRNAs are hands-on caregivers who take pride in advocating for their patients. They stay with their patients throughout their surgeries, diligently monitoring their vital signs and adjusting their anesthetics as needed. Common causes of anesthesia awareness are inadequate anesthesia and equipment failure or misuse. In some high-risk surgeries such as cardiac, trauma, and emergency cesarean deliveries, using a deep anesthetic may not be in the best interest of the patient.

In these and other critical or emergency situations, awareness might not be completely avoidable. A minority of patients who experience anesthesia awareness may develop posttraumatic stress disorder PTSD , which is associated with repetitive nightmares, anxiety, irritability, and preoccupation with death. Research into the causes and prevention of anesthesia awareness is ongoing.
