ABSTRACT

OBJECTIVE: To compare the incidence of transient tachypnea of the newborn (TTN) in infants of asthmatic vs nonasthmatic mothers. RESEARCH DESIGN: Case-control analysis. SETTING: Group model health maintenance organization. PATIENTS: A volunteer sample of 294 pregnant asthmatic women and 294 pregnant nonasthmatic women with normal pulmonary function test results, matched on the basis of age and smoking status. All subjects entered the study before their third trimester of pregnancy. Subjects with multiple gestations and abortions (less than 20 weeks' gestation) were excluded. INTERVENTION: Asthma was treated in the allergy department. Routine obstetric, neonatal, and pediatric care was provided to all patients by staff physicians. MEASUREMENTS/RESULTS: Transient tachypnea occurred in 11 infants (3.7%) of asthmatic women and in one control infant (0.3%). There were no significant differences between asthmatic and matched control subjects in previously defined TTN risk factors, such as the occurrence of longer labors, failure to progress, cesarean sections, premature births, male sex, Apgar scores of less than 7 at 1 minute, or birth weight greater than 4 kg. Although infants of asthmatic mothers were more likely to exhibit wheezing by age 15 months compared with control infants (12.0% vs 3.2%), none of the infants with TTN manifested wheezing by age 15 months. No relationships could be identified in the asthmatic cohort between the occurrence of TTN and asthma severity or medication use (during the pregnancy in general or during labor and delivery in particular). CONCLUSION: Although the mechanism is uncertain, maternal asthma appears to increase the risk of infant TTN.

ABSTRACT

To assess the safety of inhaled beta-agonist bronchodilators during pregnancy, perinatal outcomes in 259 prospectively managed women with asthma using these medications during pregnancy were compared to perinatal outcomes in 101 concurrently followed pregnant subjects with asthma not using inhaled bronchodilators and to perinatal outcomes in 295 concurrently followed pregnant control subjects without asthma. No significant differences between women with asthma using inhaled bronchodilators and subjects not receiving inhaled bronchodilators were found in the following parameters: perinatal mortality, congenital malformations, preterm births, low birth weight infants, mean birth weight, small for gestational age or low ponderal index infants, Apgar scores, labor/delivery complications, or postpartum bleeding. Increased incidences of maternal chronic and pregnancy-induced hypertension and transient tachypnea of the neonate were observed in the pregnancies of subjects with asthma using regular inhaled bronchodilators compared to control subjects, but a logistic regression analysis within the sample of subjects with asthma did not significantly associate the use of inhaled bronchodilators with these outcomes. In the light of the known substantial perinatal risks of severe, uncontrolled asthma and the relatively sparse evidence of human gestational safety for alternative asthma medications, these data support the use of inhaled beta-agonist bronchodilators as part of the management of asthma during pregnancy.

ABSTRACT

Evaluation of four patients with unilateral transverse limb reduction defects indicates that some instances of this structural defect may be the result of an in utero vascular accident. Three of the four patients had microscopic evidence of fetal vascular occlusive disease on multiple sections of the placenta, suggesting that occlusion of the brachial artery was secondary to embolization from the placental vascular thrombi. The fourth, a 116 mm crown-rump long fetus, had a massive thrombus occluding the brachial artery, which was felt secondary to hypovolemia and hypoperfusion associated with fetal blood loss during placental abruption. Recognition of the disruptive vascular pathogenesis of some cases of unilateral transverse limb reduction defects explains their negligible recurrence risk. In such cases attention should be focused on careful gross and, microscopic evaluation of the placenta.

ABSTRACT

Airway obstruction secondary to acute epiglottitis is a dramatic, life-threatening emergency. Early diagnosis and provision of an adequate artificial airway are critical in the management of these patients. Tracheostomy has been the traditional method of securing the airway in acute epiglottitis, but more recently, endotracheal intubation has been advocated. Whichever method of airway management is preferred, it is imperative that every hospital have a protocol for the management of acute epiglottitis so that immediate action can be taken.

ABSTRACT

The authors describe three cases of neonatal depressed skull fracture that were elevated by means of an obstetrical vacuum extractor. In one case, a transparent breast pump shield replaced the metal vacuum extractor cup, permitting direct observation as the depression was elevated. Neonatal depressed skull fractures not associated with neurological signs may be safely elevated without surgery using the obstetrical vacuum extractor.
