Tumescence Anesthesia Solution-Assisted Laser Ablation Treatment of Lower Limb Varicose Veins: The Effect of Temperature of the Tumescence Anesthesia Solution on Intraoperative and Postoperative Pain, Clinical Observations, and Comprehensive Nursing Care.

PURPOSE: 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. DESIGN: 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. METHODS: A numerical rating scale was used to evaluate pain. Perioperative and intraoperative nursing care and clinical observations were performed following a generalized standard. FINDINGS: 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. CONCLUSIONS: Cold TAS reduces intraoperative and postoperative pain more effectively than room temperature.
