The frequency of anesthesia awareness has been found to range between 1 and 2 per 1,000 patients undergoing general anesthesia.
1Carol Weiher: experienced it during an eye removal surgery
She desperately wanted to scream or even move a finger to signal doctors that she was awake, but the muscle relaxant she'd received prevented her from controlling her movements.
"I was doing a combination of praying and pleading and cursing and screaming, and trying anything I could do but I knew that there was nothing that was working," said Weiher, of Reston, Virginia.
The surgical tools didn't cause Weiher pain -- only pressure -- but the injections of a paralytic drug during the operation "felt like ignited fuel," she said. "I thought, well, maybe I've been wrong about my life, and I'm in hell," she said. The entire surgery lasted five-and-a-half hours. Sometime during it she either passed out or fell unconscious under the anesthetic. When she awoke, she began to scream.
"All I could say to anyone was, 'I was awake! I was awake!'” she said.
Weiher is one of few people who have experienced anesthesia awareness. Although normally a patient does not remember anything about surgery that involves general anesthesia, about one or two people in every 1,000 may wake up during general anesthesia, according to the Mayo Clinic.
2June Carson: suffered a cardiac arrest during surgery
The anaesthetist had miscalculated the dose and, while June could not move or make a sound, she could feel every torturous second of her operation. The surgeon and his staff had no idea of her suffering until it was over.
“That day I was wheeled into the anaesthetic room, where a drip was inserted in my hand and a mask over my face. I lay back, closed my eyes and expected to fall asleep slowly as I always had before. But, after a few minutes, I could still hear the doctors talking and realised something was wrong.”
“I knew they would have to make several deep cuts in my stomach. My mind was racing. Feeling the knife cutting into my stomach, I thought I would die immediately. It's impossible to describe the pain but I felt as if I was being tortured.”
After 15 minutes enduring the agony of keyhole surgery, her heart stopped from the shock.
Fortunately, with an injection of adrenaline, June's heart started to beat again.
June woke up two hours later in intensive care, remembering every nightmarish second.
3Experienced Anesthesia Awareness twice
And the other time, was at 16 years old. She was having surgery to correct some breathing problems. She could hear and feel everything. The doctors had no idea of what she was going through.
“I felt the surgeon cut through me and work to repair the problem. The pain was so excruciating that I was falling in and out of consciousness. It was terrifying.”
After it was all over, she didn't remember a thing until a few hours later. "When I asked about it, they decided to test me by showing me "partial-words" and asking me to say whatever sounded familiar (any terms I may have heard the doctors talk about.) They asked me to describe any pain I had felt, and the only thing I could remember was any time I felt a knife/blade cut me in any way. "
Then, they verified that she had experienced anesthesia awareness.
4Experienced anesthesia awareness during gallbladder surgery
Then, the surgeon began his incisions for the laparoscopic procedure. She felt the first incision near her belly button.
“At that point, I was aware, I could not scream because of the breathing tube, all I could think of is I have got to move some way; I was fighting for all I had in my mind to move as they proceeded with the second incision up by the rib cage, there is no words to describe the pain.”
Then, they placed a tube in each incision, and all this time, she was fighting for a move. The anesthesiologist said that her blood pressure went way out of control.
“The surgeon then started to do the third incision, with me still fighting to move. I remember the sticking in of the scalpel for that incision but, at that point they realized something was wrong and gave me the max amount of drugs without killing me to put me under.”
At the end of the surgery, the doctors were unable to move her to recovery for 4 hours because of her high heart rate.
When she was moved to second recovery, the nurse's first question was what her pain level was, and she answered: “it would be much lower if I had not been awake during that surgery.”
5Diane Parr: experienced it during a tooth extraction
Minutes before, the anaesthetist had administered something into a tube in the back of her hand and she felt a woozy, relaxed feeling wash over her.
She began to count backwards from ten, as instructed, but as she was wheeled into theatre, she realised she could feel the trolley judder beneath her and hear the voices of the theatre staff.
"I could feel the surgeon leaning over me and push down on my body before pulling up. It felt as if my tooth was coming out of my foot, not my mouth. A searing pain shot up my body."
"'It's a toughie', I heard him exclaim. I thought I was going to die, not because of the pain, but the fear. I thought I was going to have a heart attack."
Diane, who lives in St Teath, Cornwall, with her husband, Tim, and daughter, Dawn, 22, says the experience "ruined" her life.
6Experienced anesthesia awareness during leg surgery
7Had an out-of-body experience during a nose job
Her blood pressure, blood oxygen concentration, and blood carbon dioxide concentration remained normal throughout the operation. No-one in the operating theatre observed anything unusual during the operation. Nobody saw her soul standing next to the operating table. Her body remained on the operating table during the operation. She could not move, breathe, or speak during the operation, because she had received a drug that almost totally paralyzed all the muscles of her body, and was being mechanically ventilated through a tube placed between her vocal cords. But shortly before the end of the operation, when the effects of all the drugs she received were partly worn off, she made slight movements of her arms and legs. So, just in case she was awake, the anesthetic assistant promptly administered an extra dose of a powerful sleep-inducing drug. Otherwise, there was no reason to think she was conscious at any time during the operation. She was only capable of speaking after she awoke from the general anesthetic.
