Effects of different lifting angles of lower limb on lower limb swelling and hemodynamics in patients with great saphenous varicose vein surgery
Objective To investigate the effect of different lifting angles of lower limb on lower limb swelling and hemodynamics in patients with great saphenous varicose veins.Methods Totally 90 patients with great saphenous varicose veins admitted to our hospital from January 2021 to December 2022 were enrolled in the study.They were randomly assigned in a 1∶1∶1 ratio to group A,group B and group C according to a method of random number.The lower limbs of patients in the three groups were raised by 15°,30° and 45° respectively.All patients in the three groups were treated with great saphenous varicose vein surgery.The lower limb circumference,hemodynamic indicators,treatment effectiveness,sleep quality,comfort,and postoperative complications were included as comparisons among three groups.Results The lower limb circumferences of the three groups were significantly longer at hour 1 of surgery than those before surgery,and which of the three groups were significantly shorter at hours 8,12,and 24 of surgery than before surgery(P＜0.05).The lower limb circumference of group B and group C was significantly shorter than that of group A at hours 4,8,12,and 24 of surgery(P＜0.05).The intraoperative average arterial pressure and heart rate in the three groups were significantly lower than those before surgery,which in group A and group C were significantly higher than those in group B(P＜0.05).The skin color improvement in group B and group C on month 3 of surgery was significantly higher than that of group A(86.67％vs 60.00％,90.00％vs 60.00％,respectively;P＜0.05).The residual venous mass scores of group B and group C on month 3 of surgery were significantly lower than those of group A([0.40±0.09]points vs[0.66±0.12]points,[0.41±0.10]points vs[0.66±0.12]points,respectively;P＜0.05).The Pittsburgh Sleep Quality Index(PSQI)scores of the three groups at hour 24 were significantly higher than those before surgery,which of group A and group B at hour 24 were significantly lower than those of Group C(P＜0.05).The General Comfort Questionnaire(GCQ)scores of the three groups at hour 24 were significantly lower than those before surgery,which of group A and group B at hour 24 were significantly higher than those of group C(P＜0.05).The incidence of postoperative complications in group B and group C was significantly lower than that of group A(6.67％vs 33.33％,3.33％vs 33.33％,respectively;P＜0.05).Conclusion The lower limb elevation of 30° during the perioperative period of great saphenous varicose vein surgery can improve the sleep quality and comfort of patients with lower limb varicose veins,reduce the swelling of lower limbs,improve the stability of intraoperative hemodynamics and therapeutic effect,and reduce the incidence of postoperative complications.The effect is significant.
