Developed in China, with the belief that a life-force is essential for good health, acupuncture is an ancient therapeutic technique .The Chinese believe that the life energy (chi) flows through the body along pathways called meridians. Disrupted body functions or disease is considered the result of interrupted flow. The needles restore the flow to resolve health. Needles of length 0.5 to 5 inch (12 to127 mm) are placed in specific parts of the body to relieve a number of conditions from back pain to toothache, neuralgia, headaches and even stopping smoking. Alternative methods to acupuncture include pressure or heat being used in the place of needles.Western medicine is increasingly accepting acupuncture as a treatment and it is thought that a form of Anaesthesia may be induced by stimulation of sensory nerves. This would stimulate the pituitary gland and hypothalamus to release endorphins (the body's natural painkiller). If the patient has a strong psychological belief that it will work, this could be contributory.
Also known as a bag valve mask or BVM. It is a hand-held device which is used to provide ventilation to a patient who is not breathing or who is breathing inadequately. After it is squeezed, the bag is self-inflating. A BVM is a normal part of a resuscitation kit for trained professionals.

It is also extensively used in the operating room to ventilate an anesthetised patient in the period of time before a mechanical ventilator is attached.

Loss of feeling or awareness. General anesthetic puts a patient to sleep. Local anesthetic causes loss of feeling in a part of the body such as a tooth or an area of skin without affecting consciousness. Regional anesthetic numbs a larger part of the body without affecting consciousness. Conduction anesthetic (often used in procedures such as a C-Section) encompasses both local and regional anesthetic techniques, allowing surgical procedures to be done without significant pain.

Physician administration of anaesthetics to alleviate pain and suppress consciousness, as well as monitor and support life functions during surgery. Anaesthetists can also provide diagnosis and treatment of chronic pain.
An aneurism is a medical term for a blood vessel abnormality characterised by a weakening of the wall of an artery. This abnormality leads to a progressive 'ballooning' of the vessel wall, which forms a sac filled with blood. An aneurism can occur in many arteries in the body. Those which occur in the blood vessels of the head which supply blood to the brain are known as cerebral aneurisms.

A cataract is a clouding or opacity in the lens of the eye. A cataract obstructs the passage of light to the eye, and can vary in degree ranging from slight to complete opacity. Early development of a cataract can result in myopia (near-sightedness), while the gradual yellowing and opacification of the lens can reduce the eye’s ability to perceive blue colours. While a cataract can typically be removed by surgery, an untreated cataract can cause vision loss and blindness.

This can be achieved through the use of heat, freezing, chemical scarring, electricity, light and ultrasonic or microwave energy.
Commonly known as a 'brain aneurism', a cerebral aneurism is a blood vessel abnormality characterised by a bulging of the walls of a blood vessel which supply blood to the brain. Over time, the blood pressure inside the aneurism can lead to the expansion and eventual rupture of the aneurism.
Often confused with styes, a chalazion is a small sebaceous cyst on the eyelid which appears as a bump on the eyelid. It is caused by the inflammation of a blocked meibomian gland, which is a fat-secreting gland of the eyes. A chalazion differs from a stye (hordeolums) in that a chalazion is usually larger than a style, and it is generally painless except for the tenderness which is caused as it swells. A chalazion may eventually disappear on its own after a few months, but usually requires some treatment.
The thin, transparent mucous membrane which covers the sclera (white part of the eye), lines the inside surface of the eyelid, and extends from the edge of the eye lids to the cornea.
An alternative to general anaesthesia in patients for whom general anaesthesia is refused or considered inadvisable.

Personnel toss the used sponges into the buckets placed about the operating room. At the end of the procedure, an operating room nurse or technician can count the sponges in the bucket to ensure that all sponges used during the procedure have been accounted for.
