ABSTRACT
Objective To evaluate the clinical significance of high frequency ultrasonography in the diagnosis of annular pancreas in neonates.Methods Ultrasound results,clinical data,operation results and complicating deformity of 19 neonates were reviewed retrospectively.The digestive tracts of 19 neonates,including stomach,duodenum,jejunoileum and colon,were examined with 8-12 MHz linear transducer before surgery.Results Of 19 neonates with annular pancreas,17 cases were diagnosed with ultrasound,the diagnostic rate was 89％.The pancreas tissue encircling the descending duodenum was directly displayed as a direct sign of ultrasonography and the expansion of the proximal end of the duodenum was presented as an indirect sign of ultrasonography in 17 neonates.There were 3 neonates with annular pancreas complicating intestine malrotation and 2 neonates with annular pancreas complicating duodenal membraneous stenosis.One neonate was misdiagnosised and the other was missed.Conclusions High frequency ultrasonography plays an important role in diagnosing annular pancreas and other digestive deformity in neonates.It can be used as the first choice for the neonatal annular pancreas.
ABSTRACT
Objective To observe pre-eclampsia,maternal impact on neonatal morbidity.Methods 120 cases of preeclampsia and maternal were selected as observation group,and selected the normal maternal production of the same gestational age newborns in the control group,the occurrence of neonatal asphyxia and hyaline membrane disease,hypoxic-ischemic encephalopathy,etc.were compared.Results The incidence of small for gestational age children of the observation group was significantly higher than that of the control group(x2=65.24,18.73,all P＜0.05);There was no significant difference between the two groups of hypoxic-ischemic encephalopathy and neonatal asphyxia(P＞0.05).Mild brain injury,cerebral dysplasia incidence of the observation group were 35.0％(42/120),29.2％(35/120),which in the control group were 25.0％(30/120),17.5％(21/120).The differences between the two groups were statistically significant(x2=2.86,4.57,P＜0.05);There was no statistically significant difference between the two groups of moderate brain injury incidence(P＞0.05).There were 20 cases of fetal distress and 7 perinatal child death cases in the observation group which,in the control group were six cases and two cases,the difference was statistically significant(x2=8.45,1.85,all P＜0.05).Conclusion Preeclampsia can affect neonatal development,who have premature birth tendency and higher neonatal morbidity.
