Abstract
To investigate the effect of cold and room temperature tumescence anesthesia solution (TAS) on the treatment of lower limb varicose veins via endovenous laser ablation. On the basis of the TAS temperature, patients were divided into two groups: group A (n = 26) received room temperature (24°C) TAS, and group B (n = 25) received cold (4°C) TAS. A numerical rating scale was used to evaluate pain. Perioperative and intraoperative nursing care and clinical observations were performed following a generalized standard. Percentages of patients who felt pain in groups A and B were 69.2% and 36.0%. Average numerical rating scale scores of patients in the two groups (A and B) on the day of surgery and on postoperative days 1, 2, and 3 were 4.3 versus 2.1, 3.5 versus 1.0, 3.0 versus 0.8, and 1.6 versus 0.3, respectively. Cold TAS reduces intraoperative and postoperative pain more effectively than room temperature.
