[Postoperative modifications of blood aminoacidemic concentration].

Post-operative plasmatic aminoacid concentrations in 2 groups of patients given surgical treatment for various pathologies have been calculated. In both groups, post-traumatic protein catabolism was expressed in significant changes to the aminoacidemic pattern. It is concluded that aminoacidograms could be used as a guide to rational parenteral post-operative treatment.

Intravenous feeding in hepatectomized patients.

Ten patients, undergone major hepatic resections, treated with parenteral hyperalimentation in the postoperative period, were studied. Considered parameters were: free plasma amino acid levels and daily nitrogen balance. By comparing the trends of parameters under study with a group of patients, also hepatectomized but not treated with T.

[Popliteal aneurysm (therapeutic considerations)].

The authors show a case of popliteal artery aneurysm they had the opportunity to observe. In consideration of the high percentage of surgical failures; recorded in the treatment of the complicate forms, they point out the importance of precocious diagnosis. The Authors think the termino-terminal arterial anastomosis after aneurysmectomy has very limited indications.

[Blood amino acid pattern in thyreopathic patients. (pre- and post-operative analysis)].

On the basis of the effects, demonstrated in vitro, of the thyroid hormones on the amino-acidic metabolism at cellular level, the Authors analysed the aminoacidogram of 15 thyreopathic patients. They remarked significant preoperative modifications of some amino-acids, coming back to standard values after operation. The authors think the preoperative modifications are to be ascribed to thyreopathy, whereas the postoperative ones depend on the surgical trauma.
