Abstract

Obese patients are more prone to a life-threatening disease such as hypertension, diabetes mellitus, arteriosclerosis and et cet-e-ra. They also have a mortality rate 2-3 times of normal patients even for relative minor surgery, for example, appendicitis. Therefore the obese patients who are going to operate under general anesthesia have always exposured to certain hazards which anesthesiologists look upon with great concern.
Because the exact causes of obesity are uncertain yet and there are many problems associated with anesthetic technics, the patients with morbid obesity should be careful managed in the perioperative periods.
1864 elective surgical cases were retrospectively studied in order to determine the body mass index (BMI), ponderal index (PI) and %´ weight from data which is actually measured heights and weights and to know the correlation of them with height. Also we reviewed the problems in the anesthetic management of obesity patients.
The following results were obtained;
1. The average value of height in Korean adult man and woman was 167.87±7.07 and 159.94±4.24 cm respectively. And the weight was 61.03±8.58 and 52.91±7, 77 kg respectively.
2. A given increase in weight with constant height produced exactly the same percentage increase in the values of BMI and °o weight, but a much smaller relative increase in the ponderal index (PI).
3. The results of analyzing, with data from the 1864 surgical elective patients, the correlation of height with the BMI, PI and , % weight show the BMI and % weight satisfy the requirement of a very low correlation with height, but there is a highly significant correlation of the PI with height.
