Light Source

Hi friends.
I wish to write today on selecting a good light source.
Basically there two kinds of it
Halogen
Xenon

A. Halogen:
This is cheaper compared to Xenon.
It gives a yellow light. Some manufacturers also make a white light Halogen light source.

Advantage:
Cheaper
The bulp lasts long
Bulb change is cheaper too.

Disadvange:
The main disadvantage of halogen light source is that, in case of bleeding, red color of blood absorbs light and thus visibility due to decreased light to a great extent. For this particular reason, it can be used for basic laparoscopic procedure only.


B. Xenon:
This Light source gives white light.
Advantage:
Gives almost natural vision.
Must for advanced surgical procedures.
.
Disadvantages
Apart from initial Costs, bulb is costly too.
The life of bulp is shorter compared to halogen bulbs

Maharastra Medical Council CME Guidelines

Medical Science is dynamic and there is no end of learning for a doctor. This is in essence the concept of continuing medical education (CME). Tremendous advances are taking place in the field of medical sciences, which are continuously changing the concept, approach to management and the outcome of several diseases. The rapid pace of these advances makes it mandatory for doctors to keep themselves updated so that they may apply this information to their patient’s well being and improve the quality of care rendered to them. A doctor must never be satisfied with his/her current level of proficiency and must always strive to enhance his/her competence and knowledge by keeping abreast with the latest developments in the field.
