Cervical plexus block has been evaluated clinically for surgery of the anterior neck in 13 patients during the 10 months(from July 1981 to April 1982) at the Department of Anesthesiology in Capital Armed Forces General Hospital. We have assessed CPB for technique, onset, anesthetized area, duration, complication and supplimentary agents, and reviewed the anatomical aspects of cervical plexus. The distribution of injected local anesthetics was demonstrated under radiography using Urographin. We experienced incomplete block in 9 cases which needed substitution with Thalamonal. The incidence of complications was few and most significant complication seen in this study was respiratory difficulty. However, There was no evidence for phrenic nerve paralysis. Cervical plexus block was performed safely and effectively for surgery of the anterior neck.
Incidence

It was obtained following results on changes of various constitutions in the blood of eleven patient who had massive blood transfusion ( average 14. 6 pints of ACD stored blood) in Seoul Natioeal University Hospital. I. It revealed no definite change of hemoglobin and hematocrit value in two days after massive blood transfusion. 2. Counts in platelets in two days after transfusion decreased from normal value to about I00, 000/mm3 except one case who had transfused 35 pints of bleod. 3. No hypearpotasaemia obser ved in two days after massive transfusion with usage of the blood warmer. 4. Temporary increase of blood glueose revealed with tendency of decrease to normal values in two days after massive transfusion. 5. The pattern of respiratory alkalosis revealed in two days after massive blood transfusion. It implies that the alkalizing agent is not recommended to inject routinely for the transfused patients without checking acid-base status. 6. It is highly recommended to check body temperature, hematocrit, hemoglobin, platelets and values in arterial blood gas and apply the blood warmer for cares in massive transfused patients.
