RESUMO
Objective To evaluate the efficacy and safety of low-dose erythromycin for the prevention of feeding intolerance in preterm infants. Methods Fifty-two preterm infants (30-31 weeks' GA group) and 68 preterm infants (32-34 weeks' GA group) were randomly subdivided into prevention groups and control groups. From the second day the prevention groups received intravenously erythromycin [3 mg /(kg·d)] for 10 days,the control groups received placebo of glucose. Results In 30-31 weeks' GA group,days to achieve full enteral feeding (DAFEF) ,days to regain birth weight (DRBW) and duration of hospitalization (DH) were shorter in the prevention group as compared to those in the control group, the incidence of feeding intolerance was lower too,but there was no significant difference (P >0.05). In 32-34 weeks' GA group, DAFEF [(13.8±4.5) d],DRBW [(10.5±1.6) d],DH [(28.5±6.8) d] were significantly shorter in the prevention group than those in the control group [(17.2±4.2), (13.8±1.5), (35.5±7.2) d],the incidence of feeding intolerance in the prevention group was lower too[ 17.6%(6/34) vs 35.3%( 12/34) ], there was significant difference (P < 0.05 ). Conclusion In 32-34 weeks' GA, low-dose erythromycin can be a safe and effective method to promote food tolerance in preterm infants, but not sure in 30-31 weeks' GA.
RESUMO
Objective To study whether early treatment of aminophylline can protect renal function in neonates with perinatal asphyxia.Methods 60 neonates with perinatal asphyxia were randomly divided into 2 groups.Within the first hour after birth,the treatment group(30 cases)received intravenously a single dose of aminophylline(5mg/kg),and the control group(30 cases)received placebo of water.Urinary Nacety-?-D-Amino-Glucosidase(NAG)activity was recorded everyday during the first 3 days of life.Heart rate,respiratory rate and blood pressure were recorded per 4h.Results Urinary NAG activity of treatment group at 48h and 72h after birth were significantly lower than that of control group(P
RESUMO
Objective To study the significance of artery blood gas(ABG)of neonate cord blood on the diagnosis of asphyxia neonatorum.Methods Neonates were divided into two groups:asphyxia group and control groups.ABG were measured by AVL blood gas analysis instrument.Results pH and PO2 in the asphyxial group were lower and PCO2 was higher than those in control group(P
