Maternal antepartum antibiotic administration and patterns of bacterial resistance in early preterm neonates.

OBJECTIVE: The objective of this study was to determine the relationship between maternal antepartum antibiotic administration and antibiotic resistance patterns in preterm neonates admitted to the neonatal intensive care unit (NICU). METHODS: This was a retrospective cohort study of women and their preterm neonates delivered at a single tertiary care center over a 5-year period. Women and neonates were included if they delivered between 23 weeks 0 days and 28 weeks 6 days of gestation and neonates were admitted to the NICU. Subjects were excluded if there was incomplete antibiotic administration data or incomplete laboratory or bacterial culture data for either mothers or neonates. Data collected from maternal and neonatal charts included the type, duration, and total number of antibiotics administered to subjects, neonatal culture results within the first 7 days of life, and bacterial antibiotic resistance information. Women with neonates that cultured positive for bacteria demonstrating antibiotic resistance were compared to those whose neonates did not have antibiotic-resistant bacteria. RESULTS: 79 women with 90 neonates met inclusion criteria. Of the 79 women, 71 (89.9%) received at least 1 antibiotic antepartum. 14 neonatal bacterial isolates were resistant to at least 1 antibiotic. Antibiotic-resistant bacteria were present in 11 neonates; 3 neonates had more than 1 resistant bacteria cultured. The most common resistant bacteria cultured were Coagulase-negative Staphylococcus (6/14, 42.9%), S. aureus (3/14, 21.4%), and E. coli (2/14, 14.3%). Enterobacter spp (2) and Klebsiella pneumoniae (1) made up the remainder. Of the 11 neonates with resistant bacteria isolated, 10 of their mothers received antibiotics antepartum. Neonates with antibiotic-resistant bacterial isolates were more likely to be born at lower gestational ages (24.6 vs 25.9 weeks, p = .013) and have lower mean birth weights (679.5 vs 849.3 g, p = .009) than those without resistant bacteria. In 8 of 11 (73%) neonates with resistant bacteria, the mother received an antibiotic to which the bacteria cultured were resistant: 6 coagulase-negative Staphylococcus, 1 MRSA, and 1 S. aureus. CONCLUSIONS: Although preterm neonates are often treated for presumed sepsis, they infrequently have positive bacterial cultures. In this study, those that had positive bacterial cultures for resistant bacteria were born at earlier gestational ages and had lower birth weights. These bacteria cultured in neonates are likely to be resistant to antibiotics received by mothers in the antepartum period. Careful selection of maternal and neonatal antibiotics in the preterm setting with consideration for local antibiotic resistance patterns is suggested.

Resident Perspectives on Palliative Care at an Urban Teaching Hospital.

Background: There has been an increasing need to address end of life (EOL) care and palliative care in an era when measures to extend life for terminal illnesses are often initiated without consideration of quality of life. Addressing the barriers for resident physicians to initiate EOL conversations with patients is an important step towards eliminating the disconnect between patient wishes and provider goals. Objective: To assess resident physician perspectives on initiating palliative care conversations with terminally ill patients at an urban teaching hospital. Methods: This paper solicited the experiences of pediatric, general surgery, and internal medicine residents through an anonymous survey to assess exposure to palliative care during training, comfort with providing palliative care, and barriers to implementing effective palliative care. Results: 45% of residents reported exposure to palliative care prior to medical training. Ninety-three percent of these residents reported being formally introduced to palliative care during medical training through formal lecture, although the majority reported also being exposed through either small group discussions or informal teaching sessions. Time constraints and lack of knowledge on how to initiate and continue conversations surrounding EOL care were the greatest barriers to effectively caring for patients with terminal illnesses. Residents concurred that either attending physicians or hospital-designated palliative care providers should initiate palliative care discussions, with care managed by an interdisciplinary palliative care team; this consensus demonstrates a potential assumption that another provider will initiate EOL discussions. Conclusions: This study evaluated the current state of physician training in EOL care and provided support for the use of experience-based training as an important adjunct to traditional didactic lectures in physician education.

Percutaneous Route of Life: Chylothorax or Total Parenteral Nutrition-Related Bilateral Pleural Effusion in a Neonate?

OBJECTIVE: Peripherally Inserted Central Catheter (PICC) lines are an essential tool in the management of premature neonates. Pleural effusion (PLE) secondary to the leakage of alimentation into the pleural cavity is an encountered complication of central-line total parenteral nutrition (TPN) administration. Methods: We review a case of a premature neonate who suffered large, bilateral PLE after insertion of an upper extremity PICC line for TPN. Results: Pleural fluid biochemical analysis confirmed PICC line infiltration, predominantly with monocytes, low protein, high triglycerides and high glucose. These results favored TPN leakage over chylothorax. Conclusions: To our knowledge, this is the first case of bilateral PLE due to PICC complication in a neonate, which highlights the importance of chylothorax differential diagnosis, the role of autopsy, and the need for clinical precautions when providing premature neonates with high osmolarity TPN.

Maternal morbidity after early preterm delivery (23-28 weeks).

BACKGROUND: Previous research has focused mainly on neonatal outcomes associated with preterm and periviable delivery, but maternal outcomes with preterm delivery are less well described. OBJECTIVE: This study aimed to determine if early preterm delivery results in an increase in maternal morbidity. STUDY DESIGN: This is a retrospective cohort study conducted at a tertiary care center over a 5-year time period. Subjects were women identified by review of neonatal intensive care unit admission logs. Women were included if they delivered between 23 0/7 and 28 6/7 weeks' gestation and their neonate was admitted to the neonatal intensive care unit. The prevalence of maternal morbidities was assessed, including blood transfusion, maternal infection, placental abruption, postpartum depression or positive depression screen, hemorrhage, and prolonged maternal postpartum hospitalization. A composite outcome comprising blood transfusion, maternal infectious morbidity, placental abruption, and postpartum depression was developed. Outcomes for women who delivered between 23 0/7 and 25 6/7 weeks' gestation (early group) and 26 0/7 and 28 6/7 weeks' gestation (late group) were compared. Multivariate logistic regression analysis was performed to evaluate contributors to the composite morbidity, controlling for confounding. RESULTS: A total of 82 women met the inclusion criteria: 38 in the early group and 44 in the late group. Maternal demographics were similar between the groups. The early group was significantly more likely to experience composite maternal morbidity (60.5% vs 27.3%; P=.004) and infection (42.1% vs 13.6%; P=.006). Regression analysis determined that delivery at a later gestational age was associated with lower rates of composite morbidity (odds ratio, 0.6; 95% confidence interval, 0.41-0.83). CONCLUSION: In this study, data suggest that maternal morbidity is higher with delivery at periviable gestational ages. Composite morbidity and maternal infection were more frequent in women who delivered at less than 26 weeks' gestation. The management of women at risk for delivery at early gestational ages should include a discussion of increased maternal complications.
