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.

Objective? To explore the status quo of thirst in patients receiving cardiopulmonary bypass (CPB) during fasting and water deprivation after extubation and to analyze its influencing factors. Methods? Totally 120 patients undergoing CPB in a Class Ⅲ Grade A hospital in Nanjing from December 2017 to May 2018 were selected in this prospective study. The general information questionnaire was used to collect the data, and the patients' thirst score and unstimulated salivary flow rate (USF) were measured. SPSS 22.0 was used to analyze the factors affecting postoperative thirst in the patients. Results? The incidence rate of thirst in the CPB patients 6 h post extubation was 100%, and their thirst score was (6.20±1.90); and the patients' thirst intensified over time. Univariate analysis showed that the patients' postoperative thirst was positively correlated with postoperative body temperature, respiratory rate, serum sodium concentration and urinary volume (r=0.172, 0.105, 0.209, 0.258; P＜ 0.05), and negatively correlated with postoperative fluid balance volume and USF (r=-0.222, -0.565; P＜ 0.05). Multivariate analysis showed that USF and fluid balance volume were the main influencing factors to thirst in the patients (P＜0.05). Conclusions? The incidence rate of thirst in CPB patients is relatively high and it is associated with multiple factors. Nurses should pay attention to the patients' thirst and take targeted measures to ameliorate their thirst to improve their comfort in nursing practice.
