Abstract:
Objective:To explore the clinical effect of forced-air-warming blanket covering the macroangiopathy of lower limb on hypothemia of patients with radical breast cancer.Methods:A total of 106 radical breast cancer patients from May 2018 to May 2019 in the Central Hospital of Xiangyang City, Hugei Province, were divided into experiment group and control group with 53 cases each, in accordance with the random number table. Forced-air-warming blanket rely on the lower half body, cover a wide range from biliateral iliac spines to feet in the control group, while those cover range from biliateral iliac spines to knee in the experiment group. The nasopharyngeal temperature, heart rate, mean arterial pressure was recorded after the patients into the operation room (T 0), 30 min (T 1), 60 min (T 2), 90 min (T 3), 120 min (T 4) and at when operation was over (T 5). Meanwhile, the changes of coagulation index were compared between groups before and after operation. Results:There was no significant difference in nasopharynx temperature between groups at T 0 and T 1 ( P>0.05). From T 2 to T 5, the nasopharynx temperature was (36.41±0.61), (36.37±0.76), (36.20±0.94), (36.15±1.05) ℃ in the experiment group, and (36.05±0.73), (35.84±0.76), (35.60±0.59), (35.57±0.53) ℃ in the control group, the differences were statistically significant ( t values were 2.762-3.970, P<0.01). However, the level of heart rate, mean arterial pressure was no significant difference between groups at different operation time ( P>0.05). After operation, the thrombin time, activated partial thromboplastin time, prothrombin time, fibrinogen, platelet count was (9.43±1.51) s, (32.49±3.69) s, (13.33±2.23) s, (3.58±0.83) g/L, (199.11±20.31)×10 9/L in the experiment group, and (10.48±1.81) s, (34.36±4.14) s, (15.38±2.43) s, (3.25±0.43) g/L, (176.45±16.41)×10 9/L in the control group, the differences were statistically significant ( t values were 2.445-6.319, P<0.05 or 0.01). Inaddition, blood loss in surgery, the incidence of hypothemia, shivering were (279.56±46.03) ml, 5.66%(3/53), 16.33%(8/53) in the experiment group, and (318.66±74.47) ml, 18.87%(10/53), 33.96%(18/53) in the control group, the differences were statistically significant ( t value was 3.251, χ2 values were 4.296, 4.169, P<0.01 or 0.05). Conclusions:Forced-air-warming blanket covering the macroangiopathy of lower limb can prevent hypothemia and reduce blood loss of patients with radical breast cancer.
