ABSTRACT
Objective To observe the preventive effect of the new nursing mode on the formation of deep venous thrombosis(DVT)in pregnant women with high risk factors.Methods 186 pregnant women who had high risk factors were selected,by using digital table method they were randomly divided into control group(93 cases)and observation group(93 cases).The control group was treated with routine nursing,the observation group was given the new nursing mode on the basis of routine nursing.The postpartum 2 weeks of lower limb swelling,pain,lower extremity deep vein thrombosis formation of incidence,and the nursing satisfaction were compared between the two groups. Results 2 weeks postpartum,the incidence rates of lower limb pain occurrence,lower extremity deep vein thrombosis in the observation group were 8.6%,2.1%,which in the control group were 20.4%,9.7%,there were statistically significant differences between the two groups(χ2 =4.56,4.82,all P <0.05).The satisfaction of the observation group was 95.6%,which of the control group was 81.7%,the difference between the two groups was statistically sig-nificant(χ2 =5.27,P <0.01).Conclusion The new nursing model used in pregnant women with high risk factors can effectively prevent the occurrence of DVT,reduce the incidence of DVT,improve the satisfaction of nursing.
ABSTRACT
Objective To investigate the influence of esmolol infusion on QT dispersity(QTd)in elderly patients with coronary heart disease during perioperafive period.Methods Fifty ASA Ⅱ or Ⅲ patients with coronary heart disease aged 65-80 yr undegoing non-cardiac surgery under general anesthesia were randomly divided into 2 groups(n=25 each):control group(group C)and esmolol group(group E).Anesthesia was induced with midazolam,fentanyl and vecuronium and maintained with continuous iv infusion of propofol andvecuronium and intermittent iv boluses of fentanyl.The patients were intubated and mechanically ventilated.PETCO2 was maintained at 25-35 mm Hg.In group E a loading dose of esmolol 0.5 mg/kg was given iv over 1 min at 2 min before skin incision and was followed by esmolol infusion at 25 μg·kg-1·min-1 maintained until the end of operation.Radial artery was caunulated.MAP,HR,SpO2 and PETCO2 were continuously momtored.ECG composed of 12 leads was momtored before operation,at 30 min after skin incision,immediately after operation,and at postsurgery days 1 and 2.The longest and shortest QT intervals were measured and detected by a cardiologist not involved in the study.The QTd was calculated.The ventricular arrhythmia was also recorded.Results QTd,the incidences of QTd abnormality and ventricular arrbythmia were significantly lower in group E than in group C.Conclusion The use ofesmolol during operation may decrease QTd and prevent the occurrence ofventricular arrhythmia.
