The effect of instructing mothers in attachment behaviors on short-term health outcomes of premature infants in NICU.

BACKGROUND: The birth of a pre-mature infant and subsequent hospitalization and separation from the family can impair maternal and neonatal attachment and quality of maternal care. This study aimed to assess the effect of instructing mothers in attachment behaviors on short-term health outcomes of pre-mature infants admitted to neonatal intensive care units (NICUs). MATERIAL AND METHODS: In this quasi experimental study, 80 mothers of pre-mature infants who were admitted to NICUs at two referral health centers in northern Iran were studied in two groups in 2018. Attachment behaviors were taught to mothers in the test group during four consecutive sessions. Mother-infant attachment behaviors were evaluated at both the beginning and the end of this study using a checklist derived from Avant's Maternal Attachment Assessment Strategy. Moreover, infants' short-term health consequences were investigated in two groups. SPSS 18 statistical software was used for data analysis. RESULTS: On average, it took respectively 34.90 ± 12/65 and 31/15 ± 14/35 days for the infants in the control and the intervention group to reach full oral feeding and 38/5 (38/4-42/11) and 37 (31/85-42/14) days to gain the minimum weight required for discharge. Moreover, the mean length of stay for the infants in the control and the intervention group was 41/80 ± 13/86 and 39/02 ± 16/01 days, respectively (P > 0/05). CONCLUSION: Instructing mothers in attachment behaviors clinically improved short-term health-related outcomes. Hence, this intervention is recommended to be incorporated in the care program for mothers with pre-mature infants.

Comparison of the effect of two methods of sucking on pacifier and mother's finger on oral feeding behavior in preterm infants: a randomized clinical trial.

BACKGROUND: Oral feeding problems will cause long-term hospitalization of the infant and increase the cost of hospitalization. This study aimed to compare the effect of two methods of sucking on pacifier and mother's finger on oral feeding behavior in preterm infants. METHODS: This single-blind randomized controlled clinical trial was performed in the neonatal intensive care unit of Babol Rouhani Hospital, Iran. 150 preterm infants with the gestational age of 31 to 33 weeks were selected and were divided into three groups of 50 samples using randomized block method, including non-nutritive sucking on mother's finger (A), pacifier (B) and control (C). Infants in groups A and B were stimulated with mother's finger or pacifier three times a day for five minutes before gavage, for ten days exactly. For data collection, demographic characteristics questionnaire and preterm infant breastfeeding behavior scale were used. RESULTS: The mean score of breastfeeding behavior in preterm infants in the three groups of A,B,C was 12.34 ± 3.37, 11.00 ± 3.55, 10.40 ± 4.29 respectively, which had a significant difference between the three groups (p = 0.03). The mean rooting score between three groups of A, B, and C was 1.76 ± 0.47, 1.64 ± 0.48, and 1.40 ± 0.90 (p < 0.001) respectively. Also, the mean sucking score in groups of A, B and C was 2.52 ± 0.76, 2.28 ± 0.64 and 2.02 ± 0.74 respectively, which had a significant difference (p = 0.003), but other scales had no significant difference between the three groups (P > 0.05). The mean time to achieve independent oral feeding between the three groups of A, B, C was 22.12 ± 8.15, 22.54 ± 7.54 and 25.86 ± 7.93 days respectively (p = 0.03), and duration of hospitalization was 25.98 ± 6.78, 27.28 ± 6.20, and 29.36 ± 5.97 days (p = 0.02), which had a significant difference. But there was no significant difference between the two groups of A and B in terms of rooting, sucking, the total score of breastfeeding behavior and time of achieving independent oral feeding (P > 0.05). CONCLUSION: Considering the positive effect of these two methods, especially non-nutritive sucking on mother's finger, on increasing oral feeding behaviors, it is recommended to implement these low-cost methods for preterm infants admitted to neonatal intensive care unit.

The effect of inhaling mother's breast milk odor on the behavioral responses to pain caused by hepatitis B vaccine in preterm infants: a randomized clinical trial.

BACKGROUND: Nowadays, it is generally assumed that non-pharmacologic pain relief in preterm infants is an important measure to consider. Research findings suggest that familiar odors have soothing effects for neonates. The aim of this study was to compare the effect of maternal breast milk odor (MBMO) with that of another mother's breast milk odor (BMO) on the behavioral responses to pain caused by hepatitis B (HB) vaccine injection in preterm infants. METHODS: This single-blind randomized clinical trial was performed over the period between February 2019 and March 2020 in the neonatal intensive care unit of Babol Rouhani Hospital, Iran. Ninety preterm infants, who were supposed to receive their HB vaccine, were randomly assigned into three groups: MBMO (A), another mother's BMO (B), and control with distilled water(C). Oxygen saturation (SaO2), blood pressure (BP) and heart rate (HR) were recorded for all participants through electronic monitoring. In addition, premature infant pain profiles (PIPP) were determined through video recording for all three groups during intervention. The chi-square, ANOVA and ANCOVA were used for analyzing the data, and P < 0.05 was considered significant in this study. RESULTS: No significant differences were found between the three groups in mean ± SD of HR, BP, and Sao2 before the intervention (P > 0.05). After the intervention, however, the means for heart rate in groups A, B, and C were 146 ± 14.3, 153 ± 17.5 and 155 ± 17.7, respectively (P = 0.012). Moreover, the means for PIPP scores in groups A, B and C were 6.6 ± 1.3, 10 ± 2, and 11.4 ± 1.9, respectively (P < 0.001). There was no significant difference found between groups in their means of SaO2, systolic and diastolic blood pressure after the intervention (P > 0.05). CONCLUSIONS: The results indicate that stimulation with MBMO is effective in reducing pain in preterm infants; therefore, it can be postulated that this technique can be considered in less invasive procedures such as needling.

Maternal recto vaginal colonization in term and preterm deliveries.

BACKGROUND AND AIM: Maternal recto-vaginal organisms are the main cause of early-onset sepsis in neonates. The aim of this study was to determine the most common organisms and compare maternal recto-vaginal colonization in term and preterm delivery. METHODS: This cross-sectional study was done from October 2014 through October 2016 among participants referred to Ayatollah Rouhani Hospital in Babol, Northern Iran. All pregnant women within gestational age (GA) ≥ 26 weeks and labor pain were included in this study. By a cotton applicator, culture from the lower third of the vagina and another one from the rectum were taken and transported by Stuart media to the laboratory, and were cultured on main Medias within 24 hours. Then microorganisms in preterm and term delivery were compared together. Data were analyzed using SPSS 16. The variables were compared between two groups by chi-squared test, Fisher's exact test and logistic regression. P<0.05 was statistically considered significant. RESULTS: Among 511 mothers with successful culturing, 417 delivered at term and 94 fewer than 37 weeks. Staphylococcus epidermidis and Escherichia coli (E. coli) were the most abundant organisms. The frequency of E. coli in term and preterm delivery was 52.5% and 68.1% respectively (p=0.006). Group B strep was more frequent in term delivery (13.7% vs. 3.2%, p=0.004). CONCLUSION: Based on our findings, the frequency E. coli and other gram-negative bacteria were higher in preterm delivery groups which indicates the need to assess the efficacy of chemoprophylaxis in situations such as prolonged rupture of membrane, and preterm delivery.
