morphine and Urinary-Tract-Infections

Prophylactic cefazolin was evaluated in high-risk obstetric patients who had invasive fetal monitoring and subsequent cesarean section. A three-dose regimen of either cefazolin or placebo was administered randomly in a double-blind manner to 93 patients, 48 receiving cefazolin and 45 placebo, with the first dose given when the cord was clamped. In the placebo group, 51% of the patients were treated for endomyometritis compared to 29% in the cefazolin group. The incidence of urinary tract and wound infections was similar in the 2 groups. One patient in the active drug group was diagnosed as having septic pelvic thrombophlebitis and received multiple antibiotics and heparin before she recovered. One patient in the placebo group required triple antibiotic therapy. Operation to control infection was not required in any patients and there were no maternal deaths. The cefazolin patients had fewer degree-hours of morbidity as calculated by the quantitative fever index (P less than 0.002). The perioperative use of cefazolin was efficacious in reducing the incidence of endomyometritis, but did not prevent serious postoperative pelvic infection.

To study the association between meconium and maternal infection.. This was a retrospective cohort study of 678 pregnant women. All term deliveries during a 31-month period with meconium passage were included. Each meconium delivery was matched with a consecutive delivery without meconium at the same gestational age.. The overall infection rate was 16%, with 13% of the infections directly related to the pregnancy, labor, and delivery. The endometritis rate was 5%, with 7.1% and 3% in the meconium and no-meconium group, respectively. The chorioamnionitis rate was 8.3%, with 9.5% in the meconium and 7.1% in the no-meconium group. Factors found to be associated with overall obstetric infections had the following odds ratios (ORs) and 95% confidence intervals (CIs): meconium (OR 1.8, 95% CI 1.1, 2.8), internal monitoring (OR 3.4, 95% CI 1.9, 5.9), amnioinfusion (OR 2.0, 95% CI 1.3, 3.3), number of vaginal exams (OR 4.5, 95% CI 2.8, 7.1), length of labor (OR 2.8, 95% CI 1.8, 4.4), and cesarean (OR 3.1, 95% CI 1.9, 5.1). Logistic regression analyses revealed the following ORs and 95% CIs: 1) for endometritis-cesarean (OR 4.2, 95% CI 1.9, 8.9), internal monitoring (OR 2.5, 95% CI 1.1, 5.9), and meconium (OR 2.5, 95% CI 1.1, 5.5), and 2) for chorioamnionitis-length of labor greater than 10 hours (OR 2.7, 95% CI 1.4, 5.6), number of vaginal exams greater than seven (OR 3.4, 95% CI 1.7, 6.6), and use of internal monitors (OR 2.5, 95% CI 1.2, 5.3).. Meconium passage increases the risk of postpartum endometritis but not chorioamnionitis. Length of labor, internal monitoring, and number of vaginal exams are risk factors for chorioamnionitis.

To evaluate the obstetric antecedents of cystic periventricular leukomalacia and transient echodense periventricular lesions among preterm infants.. A cohort study of preterm singleton infants born between 25 and 33 weeks gestation.. Pavia, Italy.. Three hundred and forty-nine infants admitted to a Division of Neonatal Intensive Care who were screened for periventricular leukomalacia.. The obstetric factors in infants with either cystic periventricular leukomalacia or transient echodense periventricular lesions were compared to those in infants with negative cranial ultrasonographic findings. Stepwise multiple logistic regression analysis was used to evaluate the association between risk factors and outcomes adjusting for confounders.. The prevalence of cystic periventricular leukomalacia and transient echodense lesions was 5.7% (20/349) and 14% (49/349), respectively. The main risk factors for cystic leukomalacia were first trimester haemorrhage (OR 4.49; 95% CI 1.63-12.39), maternal urinary tract infection on admission (OR 5.71; 95% CI 1.91-17.07), and neonatal acidosis (pH < 7.2) at birth (OR 5.97; 95% CI 1.93-18.52). Meconium-stained amniotic fluid (OR 3.95; 95% CI 1.42-10.98) and long term (> 72 hours) ritodrine tocolysis (OR 2.54; 95% CI 1.28-5.05) were associated with an increased risk of echodense lesions. The likelihood of overall leukomalacia (cystic plus echodense periventricular lesions) was increased among cases with meconium-stained amniotic fluid (OR 4.06; 95% CI 1.65-10.0), long-term ritodrine tocolysis (OR 2.56; 95% CI 1.38-4.72), maternal infection (OR 1.73; 95% CI 1.0-3.0), and acidosis at birth (OR 1.98; 95% CI 1.0-3.98).. This study confirms that maternal infection, acidosis at birth, and meconium-stained amniotic fluid increase the risk of periventricular leukomalacia in preterm infants. Long-term ritodrine use seems to increase the risk for transient echodense lesions.

Azlocillin, an acylureido penicillin with bactericidal activity, is particularly effective against Pseudomonas, enterococci and Haemophilus influenzae. It is also very active against E. coli, various Proteus species and Bacteroides. Pharmacokinetic studies were carried out in 138 children of various ages (prematures, newborns, infants, schoolchildren) after administering 50-75-100 mg/kg/ body weight azlocillin via the i.v. or i.m. routes; The constant of elimination and the distribution volumes were calculated besides the serum levels. In prematures and newborns, therapeutically effective serum levels were obtained on administering 50 or 100 mg/kg body weight twice daily. Infants and older children required 100 or 75 mg/kg body weight t.i.d. Determination of azlocillin in the bronchial secretion after i.v. doses of 75 mg/kg body weight showed good elimination. Azlocillin was always identified up to the 5th hour post injectionem. Inspite of parenteral administration, azlocillin was identified in different concentrations in the meconium as well. 39 children were treated with azlocillin, 35 of whom had Pseudomonas infection. Very good results were obtained in infections of the urinary tract, wound infections, conjunctivitis, dacryocystitis and in one case of meningitis. Bronchopulmonary diseases did not take an equally good course, but in these cases the conditions had not been favourable. No serious side effects were revealed by testing several laboratory parameters.
