Objective To investigate the effect of nursing intervention on deep vein thrombosis after major bone trauma.Methods 59 cases of bone trauma surgery were selected as the research subjects,according to random number table method,they were randomly divided into the observation group and the control group.The patients of the control group received routine nursing care,and the patients of the observation group were given nursing intervention for postoperative deep vein thrombosis on the basis of the conventional nursing care.The pulmonary embolism,deep vein thrombosis and lower extremity swelling occurred rate before and after intervention of venous blood flow velocity, patients hospitalization time and quality of care scores were compared.Results The incidence rates of pulmonary embolism (0.0%),deep vein thrombosis (11.1%)and lower extremity swelling with postoperation (14.8%)of the observation group were significantly less than those in the control group(15.6%,53.1%,46.9%),there was signifi-cant differences (χ2 =4.61,11.54,6.89,all P <0.05).After intervention,the lower extremity venous blood flow velocity of two groups [(20.9 ±5.3)cm/s,(27.5 ±7.4)cm/s]was significantly higher than before intervention [(19.2 ±4.6)cm/s,(19.8 ±5.3)cm/s],there was statistically significant difference (t =1.37,4.40,all P <0.05).The stem prognosis of lower extremity venous blood flow velocity of the observation group [(27.5 ±7.4)cm/s]was significantly higher than (20.9 ±5.3)cm/s of the control group,there was significant difference (t =3.98, P <0.05).The hospitalization time in the observation group (45.2 ±5.4)d was less than (62.3 ±7.5)d in the con-trol group,and the nursing quality score (98.7 ±1.1)was higher than (91.8 ±1.7)in the control group,and the differences were statistically significant (t =9.88,18.12,all P <0.05).Conclusion Comprehensive nursing inter-vention can help improve venous blood flow velocity,reduce the incidence of deep vein thrombosis,shorten the hospital stay,and improve the quality of nursing.

Objective To explore the influence of self care interaction mode on the health behavior of the patients with thoracolumbar fracture.Methods 127 cases of thoracolumbar fracture were randomly divided into the observation group (62 cases)and the control group (65 cases)according to random digital table method.The patients of the observation group were given self nursing interactive nursing.The patients of the control group were given rou-tine nursing.The comparative study of the following indicators of the two groups of patients:(1)activities of daily liv-ing (ADL);(2)bedridden patient self -care skills of and self -care knowledge assessment;(3)satisfaction,compli-cations,the average length of days and discharged patient telephone visit the initiative.Results The discharge self nursing ability raise,health behavior change,self -care knowledge and self -care skills of the observation group were significantly better than the control group,there were statistically significant differences(P <0.05);after discharge from the hospital,bed incidence of complications (6.5%)of the observation group was significantly lower than the control group (18.1%),the difference was statistically significant (χ2 =4.16,P <0.05)and satisfaction degree (91.7 ±6.5)was higher than the control group (87.3 ±7.5),with statistically significant difference (t =3.59,P <0.05),and the average hospitalization day (16.11 ±7.61 )d was lower than that of the control group (19.95 ± 11.55)d,there was statistically significant difference (t =2.20,P <0.05).Conclusion Self care interactive mode is conducive to mining the self -care ability of patients,improve the self -care ability of patients,and has good social benefits.
