These days, blood is in very short supply. There is in great demand of blood for the
transfusion be-cause of the technical development in operation, increased life span and
increased traumatic accident. For solving this problem, we should avoid unnecessary
transfusion and we need blood component the-rapy and autotransfusion as well.
Up to now, whole blood has been used during operation sinre there is little
recognition of the importance in the blood component therapy.
For the comparative study of the effects of packed cell therapy on the numerical value
of hemoglobin, hematocrit, potassium, calcium, arterial blood tension and artierial oxygen
saturation, we used the 3 dirt-ferent groups : whole blood group, packed cell group and
mixed group.
The conclusions are summarized as following.
1) There is no statistically significant change in the value of hemoglobin and
hematocrit in all the patient who got the transfusion before and after operation.
pre op. 12.5±0.3 gm%, 38.3±1.0%
Post op. 12.9± 0.4 gm%, 38.3±1.3% (P>0.05)
pre op. results in men, 13.8±0.4 gm%, 41.2±1.2% in woes, 11.3%±0.7 gm%, 33.4±
1.0%
2) There is a statistically significant increase in the value of hemoglobin and
hematocrit after giving whole blood during operation.
pre op.11.410.7% ,35.41: 2.4%
point op.13.6±0.8% ,40.6±2.2% (P<0.05)
average transfusion amount 11.8±0.2 unit
3) There is no statistically sioificant change in the value of hemoglobin, hematocrit
after giving packed cell during operation.
pre op 12.9±0.4 gm%, 39.6±1.3%
post op 12.7±0.7 gm%, 37.6± 2.3%
4) There is no statistically significant change in the value of hemoglobin and
hematocrit during opera-tion in mixed group.
pre op. 12.4±0.5 gm%, 38.1±1.8%
post op.12.9: 0.6 gm%, 39.1±2.0%
5) The value of potassium and calcium in everts soup is within normal limit before
and after operation, There is no statistically significant change in pre-op. and post-op.
Nup and also in the comparision of 3 groups.
6) There is no stHtistidly sigiificant difference among 3 groups in the arterial oxygen
tension and arterial oxygen saturation.
Therefore, we reached the conclusion that there is no impact of giving 1 to 5 unit
packed cell during operation on the numerical value of hemoglin, hematocrit, potassium,
calcium and oxygen carrying capacity.
