[Anesthesia in patients with varicose syndrome].

Pain in the muscles and the feeling of tension in the lower legs along the varicose veins brings many patients, especially women to an operation, usually after previous attempts of conservative treatment. The aim of the work was to present the choice of analgesia for the operation of the veins of the lower limbs with the control of the post-operative analgesia. The methods included two groups of patients. One group received halothane inhalation anaesthesia in combination with nitrous oxide and oxygen, and the other ketamine hydrochloride anaesthesia applied intravenously. Postoperative pain was graded as strong, medium, mild, and painfree state. The pain intensity was assessed for each patient by the hours, and by multiplying the obtained score by the number of patients, we got the total pain scores. The pain relief 1, 2, 3, and 4 hours after the administration of propoxiphen napsilate with paracetamol was calculated according to the formula: Br = Bo-B1 (2,3,4). As compared to the placebo, we got p.o.05 in favour of the active substance after ketamine hydrochloride anaesthesia. The results have shown that postoperative pain was much lower in the group of patients who had ketamine hydrochloride anaesthesia, what together with increased oxygen saturation during anaesthesia leads to the conclusion that this anaesthesia is appropriate for operations on the veins of the lower limbs because it ensures postoperative analgesia and oxygenation without oxygen inhalation. This is important because in the region attacked by varicosity the tissue metabolism is disturbed, oxygenation decreased and the values of pCO2 increased, frequently followed by skin atrophy, lower limb edema and lymphostasis.
