ABSTRACT
Objective To observe the pregnancy outcome of perinatal in drugs abuse pregnant women.Methods The clinical data of 105 cases of newborn in pregnant women with drug abuse were analyzed retrospectively,including premature,neonatal asphyxia,low birth weight,neonatal respiratory distress syndrome (NRDS),intracranial hemorrhage,neonatal congenital malformation and death.Fifty cases of newborn of healthy pregnant women were selected as control group.The occurrence of neonatal withdrawal syndrome was observed.Results There were 80 cases of natural labor,25 cases of cesarean section in 105 cases of pregnant women with drug abuse.Among them,56 cases (53.3 ％) of premature delivery,the average birth weight was(2 534 ± 1 234) g,25 cases(23.8％) of neonatal asphyxia,18 cases(17.1％) of neonatal respiratory distress syndrome (NRDS),16 cases (15.2 ％) of intracranial hemorrhage,and 3 cases (2.9 ％) of congenital malformation.The gestational age and weight of newborn with maternal drug abusing were significantly lower than those of the control group,the incidence of premature infants,low birth weight infants,neonatal asphyxia,NRDS and intracranial hemorrhage were higher than those of the control group,and the differences were significant (P ＜ 0.05).Compared with drug abuse less than 2 years,the proportion of preterm infants,low birth weight,neonatal asphyxia and NRDS were higher than those of drug abuse more than 2 years(P ＜0.05).The proportion of preterm infants,low birth weight,neonatal asphyxia and NRDS of intravenous drug users were higher than those of oral drug users,the differences were significant (P ＜ 0.05).The red blood cellcount,aspartate amino transferase,white blood cellcount and alanine aminotransferase in the drug abusing group were higher than those in the control group,platelet and albumin were lower than those in the control group (P ＜0.05).A total of 30 neonates had the manifestations of neonatal withdrawal syndrome.In 105 cases of newborns,99 cases cured,6 cases died,the cure rate was 94.3％.The causes of death included 3 cases of NRDS complicated with pulmonary infection,1 case of severe intracranial hemorrhage,1 case of asphyxia,and 1 case of multiple organ failure.Conclusion Drug abuse can lead to the increase of premature birth rate,asphyxiation and NRDS.Late pregnant women with drug abuse can cause the incidence of neonatal withdrawal syndrome.
ABSTRACT
Objective To explore the advantages and disadvantages of helicopter emergency medical services of South China in the long-distance transport for critical patients.Methods A total of 30 patients who received helicopter emergency medical services by Guangdong Generral Hospital from August 2004 to December 2014 were selected as the observation group,and the other 30 patients with similar conditions who received ground emergency medical services were selected as the control group.To analyses the difference between the two groups in the disease,transport distance,transportation time,costs and compliction by χ2-test,t-test and nonparametric test according types of data.Results There were significantly difference between two groups in transport distances (km) [578.0 (313.0,707.5)vs.214.5 (101.5,313.5),P 0.05).Conclusions Helicopter emergency medical services could shorten the transportation time of critical patients on long distance transportation,and improve the efficiency of first-aid.However,there were many disadvantages that need to be improved in the helicopter emergency medical service of China.
ABSTRACT
Hypoglycemia is a common and early metabolic disease of neonate.Serious and persistent hypoglycemia could result in brain damage.So far the pathogenesis of the disease is on research,but the definition of hypoglycemia,the glucose threshold of intervention,and diagnostic criteria of brain damage are still unclear.The pathogenesis of hypoglycemia is complicated.Brain damage may be related to the specific excitory amino acids receptors,reduced blood flow in occipital lobe,and cerebral hypoxia and ischemia.Diffusion weighted imaging of brain MRI and magnetic resonance spectroscopy are strongly recommended for the diagnosis of brain damage.Besides,clinical manifestation and cerebral function monitor are also included in the diagnosis.The threshold of intervention is suggested as serum glucose concentration with 2.2 ～ 2.6 mmol/L.
