ABSTRACT
Objective To explore the effect of different states of the environment to the rehabilitation process and complications of preterm infants in the different environment in neonatal intensive care unit (NICU). Methods 120 premature infants were divided into observation group and control group with 60 cases in each group by random digital table method. The control group was treated with routine nursing model, while observation group was treated with bird nest nursing, lower noise and using cyclic lights. Oxygen time and hospitalization time, increasing about body weight, sleeping time on the twenty-eighth days and the incidence of complications between the two groups were compared. Results The hospitalization and oxygen time were (41.79±2.51)days and (11.45±5.22)days respectively in the observation group, those were shorter obviously than that in the control group [(45.32±3.85)days and(15.52±5.89)days, t=5.95, 4.01, P<0.01].The growth of body weight was (17.36±2.94) g/d, the sleeping time on the twenty-eighth day was (21.18 ±0.39)hours in the observation group. It was increased than that in the control group [(13.48±4.63)g/d and(19.56±0.45)hours], and the difference was significant(t=5.48, 21.07, P<0.01). The incidences of nosocomial infection and feeding intolerance in the observation group were reduced significantly, the difference was significant ( X2=7.06, 8.71, P<0.01). Conclusions Improving the environment in NICU can prevent the adverse factors on premature infants, promote the recovery and growth of premature infants.
ABSTRACT
A method for the determination of 9 phenoxy acid herbicides in soil by solid phase extraction and LC/MS/MS with matrix correction was developed. The sample was treated by ultrasonic extraction twice with 1. 5% formic acid in acetonitrile. The extract was cleaned up with NH2 solid phase extraction column. A C18 column with formic acid in pure water/methanol mixture as the mobile phase was used under gradient elution. Mass spectral acquisition was done in negative ion mode by multiple reactions monitoring ( MRM ) . Two transitions per compound were used to provide qualitative and quantitative analysis. There were good linear relationships in the range of 2-250 μg/L for 9 phenoxy acid herbicides. The correlation coefficients were in the range of 0 . 9927-0 . 9972 . The method detection limits were in the range of 1 . 66-3 . 82 μg/kg . The average recoveries at three spiked levels ( 10 , 40 , 200 μg/kg ) ranged from 85 . 3% to 110 . 0% with the relative standard deviations (RSD) of 3. 2%-12%.
ABSTRACT
Objective To investigate the effects of environmental intervention on growth hormone (GH) and insulin-like growth factor 1(IGF-1) in very low birth weight infants in NICU.Methods 60 cases of very low birth weight infants were randomly divided into the experimental group and control group (30 cases in each group) in NICU from June 2012 to June 2013.By adjusting the light,reducing the noise,focusing the nursing time,the levels of growth hormone and insulin-like growth factor-1 were detected and the growth indexes were measured including body weight,length,and head circumference on the 7th day and 14th day.Results The indicators of growth and development in the experimental group on the 7th day and 14th day after birth were significantly better than those of the control group.The IGF-1 level in the experimental group on the 7th day was significantly higher than that of the control group.The GH and IGF-1 level in the experimental group was significantly higher than that of the control group.Conclusions Effective environmental intervention in NICU can improve the GH and IGF-1 lev-el of very low birth weight infants and improve their quality of life.
