The treatment for varicose veins with EVL is safe in patients with active ulcers. Wounds healed faster than in patients undergoing clinical treatment alone during a 1-year period. There was no ulcer recurrence in patients treated with EVL.

Propofol (3.0 mg kg(-1)) preceded by fentanyl (3.0 microg kg(-1)) was adequate for the induction of anaesthesia in children and provided adequate tracheal intubating conditions without significant haemodynamic changes. This method represents a useful alternative technique for tracheal intubation when neuromuscular blocking drugs are contraindicated or should be avoided.

The addition of sufentanil 5.0 and 7.5 microg to hyperbaric bupivacaine provided adequate anaesthesia for Caesarean section and good postoperative analgesia. Pruritus was the most common side-effect and had a significantly higher incidence when a dose of sufentanil 7.5 microg was used.

It is common belief that the use of high-heeled shoes is deleterious to venous return, by impairing the efficiency of the muscular calf pump. Ambulatory venous pressure obtained with dorsal foot venipuncture is the gold standard in the evaluation of venous pressure during walking, but it is not routinely used in clinical practice. The objective of the present study was to determine the variations in leg venous pressure obtained with a new noninvasive method, in individuals without venous disease, walking without shoes and wearing high-heeled shoes. A new method of evaluation of the venous pressure by means of air plethysmography was applied to 10 volunteers (20 limbs). The patients were evaluated while standing, with orthostatic flexion and extension foot movements, and while walking on a treadmill barefooted and wearing high-heeled shoes. It was found that the variation on the cuff pressure during walking with high-heeled shoes was higher than the variation on the cuff pressure walking barefooted (52.2 +/- 8.89 X 26.65 +/- 6.7 mm Hg, p < 0.0001), and the final hydrostatic venous pressure was lower (51.5 +/- 12.78 X 61.5 +/- 8.44 mm Hg). The use of high-heeled shoes increases muscular effort during walking and diminishes the leg venous pressure compared with barefooted.
