Methods:Ninety eight patients were selected in 2012 July~2013 year in July in our hospital, were treated with mechanical ventilation, were randomly divided into observation group and control group, 49 cases in each group, the control group using ICU routine care, the observation group in the control group on the basis of comprehensive nursing intervention, observation and nursing effect of the two groups. Results:The group of patients with mechanical ventilation time, hospitalization time was shorter than the control group, comparing the data between the groups, the difference was statistically significant(t=8.3678, t=5.9103; P<0.05). The observation group patients with unplanned estuation, ventilator-associated pneumonia was lower than the control group, the mortality rate was lower than the control group, comparing the data between the groups, the difference was statistically significant (x2=5.0178, x2=10.2424, x2=5.9905;P<0.05). Conclusion:in critically ill patients were given comprehensive nursing intervention can shorten the duration of mechanical ventilation and hospitalization in patients with mechanical ventilation, to reduce the unplanned extubation and ventilator-associated pneumonia, reduce mortality, it is worth promoting in clinical use.

Objective To study the effect of maternal hypertensive disorders complicating pregnancy on brain development of the neonates. Methods Insular area,circle and cerebral gyri width of lobus frontals were measured in 56 neonates of the mothers with hypertensive disorder complicating pregnancy(HDCP)by ultrasound and were compared with those of 53 neonates of the mothers without HDCP(control group). Results In the control group,the cerebral gyri width of term neonates was narrower than that of preterm neonates,while the insular circle was longer and the insular area was larger in the term neonates(P<0.01).Insular circle was significantly shorter and the insular area was significantly smaller in neonates of HDCP mothers [term:(87.43±10.21)mm,(413.60±90.05)mm2;preterm:(72.59±7.50)mm,(285.71±48.62)mm2]than those of the corresponding neonates in the control group[term:(102.14±9.97)mm,(557.08±98.89)mm2:preterm:(78.42±10.14)mm,(356.01±93.07)mm2].Cerebral gyri width were significantly wider only in the full term neonates.The incidence of small gestational age neonates was 30.36%(17/56)in hypertensive disorder complicating pregnancy group.The neonatal behavioral neurological score of hypertensive disorder complicating pregnancy group was significantly lower than that of control group (P<0.01). ConclusionsMaternal hypertensive disorder complicating pregnancy may result in poor development of brain of their neonates,which could be evaluated by cerebral ultrasound.
