Medical Lab Techniques - Stethoscope

Medical Lab Techniques

In medical therapeutics both diagnosis and treatment are the two
important vital aspects. Diagnosis involves identifying or determining the
nature of disease while treatment involves the curative aspects in order to
eliminate the disease causing agent. The clinical laboratory tests help a
physician in correct diagnosis and treatment.

Stethoscope

A stethoscope is used to hear the heart beat sounds, sound due to
inhalation and exhalation of air in the lungs and the respiratory pathways and also the stomach movement. It is a very useful diagnostic tool to help localize
problems and to diagnose disease.

Stethoscopes are also used along with the sphygmomanometer. The first usable binaural stethoscope was invented in 1855. The modern electronic stethoscopes are high precisioned instruments.

These can be used to hear a patient’s heart and lung clearly even in high noisy environments and even through layers of clothing. The electronic stethoscopes also make it possible to hear the foetal sounds in mother’s womb.

Uses

1. Stethoscope helps to find normal (lub-dub) versus abnormal heart sounds
(heart murmurs) and also to diagnose valve functions.
2. Stethoscopes can indicate fluid in lungs in case of pneumonia and
pulmonary edema. It can diagnose airway diseases like bronchitis and
pleuritis.
3. Stethoscopes are also used to compare the movements in the normal
versus overactive or underactive intestinal tract.

Root Canal Treatment

Image
Root Canal Treatment Root Canal Treatment is a modern dental procedure to save a tooth in which the pulp (the living tissue within a tooth) has died or become untreatably diseased, usually as a result of extensive dental caries. Steps involved in Root Canal Treatment (1) A hole is drilled into the crown to remove all material from the pulp chamber. The root canals are then cleaned with fine-tipped instruments. The procedure is usually monitored by X-rays. (2) The cavity is washed out, and antibiotic paste and a temporary filling are packed into it. Some days later, the filling is removed and the canals are checked for sterlity. (3) When no infection can be detected, the cavity is filled with a sealing paste and/or tapering solid “point” made of gutta – percha resin mixed with zinc and bismuth oxides. The mouth of cavity is then sealed with cement. Related Topics in Zoology: Bio Zoology All Important Topics Human Physiology Introduction Nutrition Carbohydrates Poly hydroxyaldehydes...

Eye Infections and Eye Care

Image
Eye Infections and Eye Care Eye Infections 1. Stye A stye is an acute infection of the glands located at the eyelid margin. There is swelling, pain, itching and redness in a small area at the lid margin. Treatment consists of using frequent warm compresses on the eye. (Eye Infections) 2. Conjunctivitis: Infection in the conjuctiva is called conjunctivitis. Due to the infection the invisible blood vessels within the conjunctiva become engorged. Inflammation of the conjuctiva causes redness, discomfort and a discharge from the affected eye. The most common causes for conjunctivitis are infections (in children) and allergy (in adults). (Eye Infections) 2a. Infective conjunctivitis : Most conjunctival infection are caused by bacteria (e.g staphylococci) and are spread by hand-to-eye contact or by viruses associated with a cold, sore throat, or illness such as measles, viral conjunctivitis sometimes occurs in epidemics, spreading rapidly through schools and other groups. (Eye Infections) 2b...
