Effect of early combined functional exercise on lower limb rehabilitation of vessel bridge taken in coronary artery bypass surgery

Abstract

Objective To investigate the effect of early combined functional exercise on lower limb rehabilitation of vessel bridge taken in coronary artery bypass surgery. Methods From January to October 2017, 90 patients undergoing coronary artery bypass surgery were randomly divided into control group and experimental group by coin toss, with 45 patients in each group. The control group was given routine nursing care, and the experimental group was given early combined functional exercise (foot dorsiflexion, ring rotation exercise and straight leg raising exercise) on the basis of routine nursing care. The difference of correlation index between two groups was compared. Results In the experimental group, the number of swelling in the thigh, crus and ankle were 20, 25 and 35 respectively; the control group was 32, 35, 43, the difference was statistically significant(χ2=6.55, 5.00, 8.38, P<0.05). The remission of limb swelling in the experimental group was also better than that in the control group(P<0.01). The incidence of limb wound complications: 6 cases in the experimental group, 18 cases in the control group (χ2=11.79, P<0.01)); limb muscle strength grade Lovett: experimental group 0 case with grade 3, 19 cases with grade 4, 26 cases with grade 5, control group 9 cases with grade 3, 26 cases with grade 4, 10 cases with grade 5, there were significant differences between two groups (χ2=17.20, P<0.05). The limb comfort score, postoperative bed time, postoperative hospital stay was (7.11±1.15) points, (5.28±1.07) d, (11.04±2.01) d in the experimental group and (5.18±1.13) points, (6.97±1.21) d, (12.67±1.59) d in the control group, the differences were significant(t=-8.02, 6.97, 4.23, P<0.01). Conclusions To carry out early functional exercise can not only take angiogenesis effectively reduce limb swelling rate after coronary artery bypass grafting, relieve the severity of limb swelling, but also can reduce the incidence of incision complications, promote the recovery of limb muscle strength, shorten the postoperative recovery time and postoperative hospitalization time, is worthy of promotion and use in clinical nursing work Key words: Functional exercise; Early rehabilitation; Vascular bridge; Lower limb; Coronary artery bypass grafting
