A trial project by the Montreal Children’s Hospital suggested that the use of medical hypnosis (催眠) can reduce pain and anxiety in patients. The project also resulted in a reduction in the amount of medicines used to perform medical-imaging imaging (医学影像) procedures.

“During the examination children don’t move. It works perfectly. It’s amazing,” said Johanne L’Ecuyer, a medical-imaging technologist at the hospital.

The project was inspired by a French team from Rouen University Hospital Centre where examinations are done under hypnosis instead of general anesthesia (麻醉).

A French medical-imaging technologist-also a hypnotist-was invited to train a few members in the medical-imaging department of the children’s hospital. In all, 80 examinations were conducted for the project between January and September, 2019, focusing on the imaging procedures that would cause anxiety.

Hypnosis is not a state of sleep: It is rather a modified (改变) state of consciousness. The technologist will guide the patient to this modified state-an imaginary world that will disassociate itself more and more from the procedure that follows.

“The technologist must build up a story with the patient,” Ms. L’Ecuyer said. “The patient is left with the power to choose what he wants to talk about. Do you play sports? Do you like going to the beach? We establish a subject that we will discuss throughout the procedure”.

Everything that happens next during the procedure must be related to this story-an injection (注射) becomes the bite of an insect: the heat on the skin becomes the sensation of the sun and a machine that rings becomes a police car passing nearby.

“The important thing is that the technologist associates what is happening outside the patient’s body with what the patient sees in his head.” Ms. L’Ecuyer said. “It requires creativity on the part of the technologist, imagination, a lot of patience and kindness.”

“The procedure appealed to the staff a lot when it was introduced in January. It spread like wildfire that someone from France was here to train the technologists,” Ms. L’Ecuyer said. She added that she had a line of staff at her door wanting to take the training.

Muscle tissue also tends to keep vaccine reactions localized at the injection site. If certain vaccines are injected into fat tissue, the chance of irritation and side effect increases because fat tissue has poor blood supply, leading to poor absorption of some vaccine components. Vaccines must be given in a muscle to avoid widespread side effect.

Yet another deciding factor in vaccine administration location is the size of the muscle as well as convenience.
