THE EFFECT OF RACE ON FUNCTIONAL RESIDUAL CAPACITY AND RESPIRATORY SYSTEM COMPLIANCE IN VERY LOW BIRTH WEIGHT (VLBW) INFANTS † 1358

Introduction: In very low birth weight (<1,500 g, VLBW) infants, morbidity and mortality have decreased substantially during the past decades, and both are known to be lower in girls than in boys. In this study, we assessed sex-specific changes over time in length of hospital stay (LOHS) and postmenstrual age at discharge (PAD), in addition to survival in VLBW infants. Methods: This is a single-center retrospective cohort analysis based on quality assurance data of VLBW infants born from 1978 to 2018. Estimation of sex-specific LOHS over time was based on infants discharged home from neonatal care or deceased. Estimation of sex-specific PAD over time was based on infants discharged home exclusively. Analysis of in-hospital survival was performed for all VLBW infants. Results: In 4,336 of 4,499 VLBW infants admitted from 1978 to 2018 with complete data (96.4%), survival rates improved between 1978–1982 and 1993–1997 (70.8 vs. 88.3%; hazard ratio (HR) 0.20, 95% confidence interval 0.14, 0.30) and remained stable thereafter. Boys had consistently higher mortality rates than girls (15 vs. 12%, HR 1.23 [1.05, 1.45]). Nonsurviving boys died later compared to nonsurviving girls (adjusted mean survival time 23.0 [18.0, 27.9] vs. 20.7 [15.0, 26.3] days). LOHS and PAD assessed in 3,166 survivors displayed a continuous decrease over time (1978–1982 vs. 2013–2018: LOHS days 82.9 [79.3, 86.5] vs. 60.3 [58.4, 62.1] days); PAD 40.4 (39.9, 40.9) vs. 37.4 [37.1, 37.6] weeks). Girls had shorter LOHS than boys (69.4 [68.0, 70.8] vs. 73.0 [71.6, 74.4] days) and were discharged with lower PAD (38.6 [38.4, 38.8] vs. 39.2 [39.0, 39.4] weeks). Discussion/Conclusions: LOHS and PAD decreased over the last 40 years, while survival rates improved. Male sex was associated with longer LOHS, higher PAD, and higher mortality rates.

Background Gastrointestinal (GI) perforation is a risk factor for mortality in very low birth weight (VLBW) infants. Little data exist regarding pretreatment factors and patient characteristics known to independently correlate with risk of death. Materials and Methods A retrospective review of all VLBW infants who sustained GI perforation between 2011 and 2018 was conducted. Birth, laboratory, and disease-related factors of infants who died were compared to those who survived. Results 42 VLBW infants who sustained GI perforations were identified. Eleven (26.19%) died. There were no significant differences in birth-related factors, hematological lab levels at diagnosis, presence of pneumatosis, or bacteremia. Portal venous gas ( P = .03), severe metabolic acidosis ( P < .01), and elevated lactate at diagnosis ( P < .01) were statistically more likely to occur among infants who died. Discussion Portal venous gas, severe metabolic acidosis, and elevated lactate were associated with an increased risk of mortality among VLBW infants who develop a GI perforation. Further research is required to better identify risk factors.

Focal Intestinal Perforation

Introduction We present a single-center experience with very low birth weight (VLBW) infants with focal intestinal perforation (FIP), comparing the results of primary anastomosis (PA) and stoma opening (SO). Materials and Methods Clinical records of VLBW infants with FIP who underwent surgery between 2006 and 2015 were reviewed. Patients were divided into two groups according to the procedure performed: limited bowel resection and PA or SO. Patients with gastric perforation or patients who underwent clip and drop were excluded. Information regarding birth weight (BW), gestational age (GA), weight at surgery (WS), number of abdominal reoperations, duration of parenteral nutrition (PN), and demise was recorded. Results In this study, 40 patients were included: 22 in PA group and 18 in SO group. BW was 865 g in PA and 778 in SO (p-value: 0.2). GA was 26.1 weeks in PA and 25.6 in SO (p-value: 0.3). WS was 1,014 g in PA and 842 in SO (p-value: 0.09). Duration of surgery was 115 minutes in PA and 122 in SO (p-value: 0.67). Five patients (23%) belonging to PA group developed complications and required SO. Five patients (23%) demised in PA group and six (33%) in SO (p-value: 0.2). Seventeen abdominal reoperations were performed in PA group and 22 in SO group (p-value: 0.08). Conclusion Both procedures appear to be safe. When possible, PA should be performed as it reduces the number of abdominal reinterventions.

Rbc Transfusion

Background: Red blood cell (RBC) transfusion improves cardiorespiratory status of preterm infants by increasing circulating hemoglobin, improving tissue oxygenation, and reducing cardiac output. However, RBC transfusion itself has also been suggested to negatively affect short-term outcomes such as intraventricular hemorrhage (IVH), bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), and necrotizing enterocolitis (NEC) in premature infants.Purpose: This study aimed to analyze the relationship between RBC transfusion and short-term outcomes in very low birth weight (VLBW) infants (birth weight, <1,500 g).Methods: We retrospectively reviewed the medical records of VLBW infants admitted to the Soonchunhyang University Bucheon Hospital between October 2010 and December 2017. Infants who died during hospitalization were excluded. The infants were divided into 2 groups according to RBC transfusion status. We investigated the relationship between RBC transfusion and short-term outcomes including BPD, ROP, NEC, and IVH.Results: Of the 250 enrolled VLBW infants, 109 (43.6%) underwent transfusion. Univariate analysis revealed that all shortterm outcomes except early-onset sepsis and patent ductus arteriosus were associated with RBC transfusion. In multivariate analysis adjusted for gestational age, birth weight and Apgar score at 1 minute, RBC transfusion was significantly correlated with BPD (odds ratio [OR], 5.42; P<0.001) and NEC (OR, 3.40; P= 0.009).Conclusion: RBC transfusion is significantly associated with adverse clinical outcomes such as NEC and BPD in VLBW infants. Careful consideration of the patient’s clinical condition and appropriate guidelines is required before administration of RBC transfusions.
