RESUMO

Aim: The aim of the present study is to investigate the neuroprotective effects of l-Arginine (l-arg) in the seven-day-old rat hypoxia-ischemia model. Materials and methods: L-Arginine (n = 10) or saline (n = 8) was administered intraperitoneally to seven-day-old rats before hypoxia-ischemia. In addition, 18 seven-day-old rats were given l-Arginine (n = 10) or saline (n = 8) after hypoxic-ischemic insult. Neuronal apoptosis was investigated by terminal dUDP-biotin nick end-labeling (TUNEL) following three days of recovery. The ratios of right side numerical density to the sum of right and left sides' numerical densities (right apoptosis index) were calculated for every brain region in rats receiving l-arginine and they were compared with the vehicle groups. Results: Right side apoptosis indexes of the hippocampus (mean ± SD; 35.0 ± 16.1) and striatum (41.9 ± 16.0) were significantly decreased in the l-Arginine post-treatment groups when compared to vehicles (61.0 ± 17.0 and 62.4 ± 27.0 respectively) (p < 0.05). There was no significant difference in the right apoptosis indexes of the cortex between l-Arginine post-treated group and the vehicle group. There were also no significant differences between the right side apoptosis indexes of the l-Arginine pretreatment groups and those of the vehicle group in any of the three regions (p > 0.05). Conclusions: It is concluded that neuronal apoptosis due to hypoxic-ischemic injury may likely to be reduced by post-treatment of l-Arginine in the neonatal rat model and l-Arginine provides a new possibility for neuroprotective strategies based on NO production.

RESUMO

AIM: Most of the preterm infants are transfused at least once during their stay in the neonatal intensive care unit (NICU). The aims of this study were to demonstrate if packed red blood cell (pRBC) transfusion modulates regional (cerebral, abdominal, renal) tissue oxygen saturation measured by near-infrared spectroscopy (NIRS) and to demonstrate if we can use NIRS to guide transfusion decisions in neonates. METHODS: A multi-probe NIRS device was applied to anaemic preterm infants of gestational age <33 weeks for 30-60 min before and 24 h after pRBC transfusion. We evaluated the results separately in the subgroup with a pre-transfusion haemoglobin (Hb) < 8 g/dL. Cerebral, abdominal and renal tissue oxygen saturation (rSO2 ) and abdominal/cerebral, abdominal/renal and renal/cerebral rSO2 ratios before and 24 h after transfusion were compared. RESULTS: There was no significant difference in cerebral rSO2 and abdominal/renal rSO2 ratios before and 24 h after transfusion, but abdominal and renal rSO2 and abdominal/cerebral and renal/cerebral rSO2 ratios at the 24th h following transfusion increased significantly. This increase was observed in the subgroup with pre-transfusion Hb < 8 g/dL. Although statistically significant, the increase in renal oxygenation was within the limits of variability. CONCLUSIONS: The increase in tissue oxygenation in abdominal region after pRBC transfusion suggests decreased tissue oxygenation of intestines during severe anaemia despite cerebral oxygenation being maintained at that particular Hb level. The impact of the increase on renal oxygenation with pRBC transfusion is unclear and might need further investigation. Increase in abdominal rSO2 may cause reperfusion injury, oxidative damage and trigger necrotising enterocolitis.

RESUMO

OBJECTIVE: The objective of this study is to evaluate if echocardiographic examination causes any pain response in term and preterm infants. METHODS: Term and preterm neonates who admitted to Neonatal Intensive Care Unit at Gazi University Hospital and Etlik Zubeyde Hanim Training and Research Hospital and were performed echocardiography for any reason were included into the study. Neonates were evaluated before, during and 10 minutes after the examination. Vital signs (heart rate, respiratory rate, blood pressure, transcutaneous oxygen saturation) were recorded. All subjects were also evaluated with Neonatal Infant Pain Scale during the examination. RESULTS: In this study, we evaluated 99 newborn infants. Five infants who received fentanyl treatment were excluded. The heart rate (p = 0.000), respiratory rate (p = 0.000), diastolic blood pressure (p = 0.001) and oxygen saturation (p = 0.000) during the examination were significantly different than the values before and 10 minutes after the examination. Infants whose gestational age ≤32 weeks (n:20) have significantly higher NIPS scores (mean ± SEM = 3.3 ± 0.4) than the infants whose gestational age is greater than 32 weeks (n:71) (mean ± SEM = 2.4 ± 0.2). CONCLUSIONS: Echocardiographic examination which is known as noninvasive and painless causes significant pain in preterm infants.

RESUMO

OBJECTIVE: The aim of this study is to investigate the effects of family centered physiotherapy according to the neurodevelopmental treatment (NDT) principles on mental and motor performance in premature infants. METHODS: A total of 156 infant, ≥24/36 week+6days gestational age included in the study. All the infants were diagnosed by a child neurologist and referred to psychology and physiotherapy department for their neurodevelopmental assessment and treatment. Bayley Scale of Infant II (BSI-II) was used for neurodevelopmental assessment and Alberta Infant Motor Scale (AIMS) was used for assessing their motor performance. Seventy-eight of the infants were in the study group and 76 were recruited as age matched controls according to the classification of their gestational age. Family centered physiotherapy according to the neurodevelopmental treatment principles was used as an intervention and all the mothers are trained accordingly. RESULTS: Cognitive Development Scores and Motor Development Scores of Bayley II were recorded for the 3., 6., 9., and 12 months respectively. Between the 3. and 12. month of gestational age, within-groups measurements in both Cognitive Development Scores (p<0.001) and Motor Development Scores (p<0.001) were significantly increased. However, the improvements in both Cognitive Development Scores (p=0.059) and Motor Development Scores (p=0.334) between the groups was not different. CONCLUSION: Family centered physiotherapy with NDT principles may not be enough to improve motor and cognitive performance in preterm infants at the first year of age. For supporting the motor and cognitive development of the preterm infants other intervention modalities also should be considered.

RESUMO

BACKGROUND: Volume-controlled ventilation modes have been shown to reduce duration of mechanical ventilation, incidence of chronic lung disease, failure of primary mode of ventilation, hypocarbia, severe intraventricular hemorrhage, pneumothorax, and periventricular leukomalacia in preterm infants when compared with pressure limited ventilation modes. Volume-guarantee (VG) ventilation is the most commonly used mode for volume-controlled ventilation. Assist control, pressure-support ventilation (PSV), and synchronized intermittent mandatory ventilation (SIMV) can be combined with VG; however, there is a lack of knowledge on the superiority of each regarding clinical outcomes. Therefore, we investigated the effects of SIMV+VG and PSV+VG on ventilatory parameters, pulmonary inflammation, morbidity, and mortality in preterm infants. METHODS: Preterm infants who were born in our hospital between 24-32 weeks gestation and needed mechanical ventilation for respiratory distress syndrome were considered eligible. Patients requiring high-frequency oscillatory ventilation for primary treatment were excluded. Subjects were randomized to either SIMV+VG or PSV+VG. Continuously recorded ventilatory parameters, clinical data, blood gas values, and tracheal aspirate cytokine levels were analyzed. RESULTS: The study enrolled 42 subjects. Clinical data were similar between groups. PSV+VG delivered closer tidal volumes to set tidal volumes (60% vs 49%, P = .02). Clinical data, including days on ventilation, morbidity, and mortality, were similar between groups. Chronic lung disease occurred less often and heart rate was lower in subjects who were ventilated with PSV+VG. The incidence of hypocarbia and hypercarbia were similar. Interleukin-1ß in the tracheal aspirates increased during both modes. CONCLUSION: PSV+VG provided closer tidal volumes to the set value in ventilated preterm infants with respiratory distress syndrome and was not associated with overventilation or a difference in mortality or morbidity when compared to SIMV+VG. Therefore, PSV+VG is a safe mode of mechanical ventilation to be used for respiratory distress syndrome.

RESUMO

BACKGROUND/AIM: Increased airway resistance reduces the effectiveness of ventilation treatment. Endotracheal tubes (ETTs) and connectors contribute to resistance. However, the effect of a closed system suction (CSS) connector is not well known. We compared the in vivo resistance occurring with a CSS connector with that of the standard connector. MATERIALS AND METHODS: This prospective study was conducted at Gazi University Hospital's neonatal intensive care unit. Intubated neonates were studied for two cycles; each cycle contained two periods of ETT + connector pairs (15 min/period) as follows: cycle 1 [A: long ETT + standard connector; B: long ETT + CSS connector] and cycle 2 [C: shortened ETT + standard connector; D: shortened ETT + CSS connector]. Resistance of 40 breaths/period was averaged for each case, and the means were analyzed by Wilcoxon test for pairwise comparisons between standard and CSS connectors. As each case provided two cycle data, 16 cycle data were compared. RESULTS: The CSS connector increased resistance by 13.8% (range: 3.0%-22.1%) compared to the standard connector; P < 0.001. The resistance increase was similar between long [17.3% (range: 3.0%-17.7%)] and shortened ETTs [15.3% (range: 5.0%-29.6%)]; P = 0.834. CONCLUSION: CSS connectors were found to increase airway resistance in ventilated neonates. The contribution of CSS should be considered during ventilation, particularly in the presence of difficulty in providing sufficient tidal volume.

RESUMO

OBJECTIVE: More information is needed on "low-risk" preterm infants' neurological outcome so that they can be included in follow-up programs. A prospective study was performed to examine the regional brain volume changes compared to term children and to assess the relationship between the regional brain volumes to cognitive outcome of the low-risk preterm children at 9 years of age. PATIENTS: Subjects comprised 22 preterm children who were determined to be at low risk for neurodevelopmental deficits with a gestational age between 28 and 33 weeks without a major neonatal morbidity in the neonatal period and 24 age-matched term control children term and matched for age, sex, and parental educational and occupational status. METHODS: Regional volumetric analysis was performed for cerebellum, hippocampus, and corpus callosum area. Cognitive outcomes of both preterm and control subjects were assessed by Weschler Intelligence Scale for Children Revised (Turkish version), and attention and executive functions were assessed by Wisconsin Card Sorting Test and Stroop Test TBAG version. RESULTS: Low-risk preterm children showed regional brain volume reduction in cerebellum, hippocampus, and corpus callosum area and achieved statistical significance when compared with term control. When the groups were compared for all WISC-R subscale scores, preterm children at low risk had significantly lower scores on information, vocabulary, similarities, arithmetics, picture completion, block design, object assembly, and coding compared to children born at term. Preterm and term groups were compared on the Stroop Test for mistakes and corrections made on each card, the time spent for completing each card, and total mistakes and corrections. In the preterm group, we found a positive correlation between regional volumes with IQ, attention, and executive function scores. Additionally, a significant correlation was found between cerebellar volume and attention and executive function scores in the preterm group. CONCLUSION: Low-risk preterm children achieve lower scores in neurophysiological tests than children born at term. Preterm birth itself has a significant impact on regional brain volumes and cognitive outcome of children at 9 years of age. It is a risk factor for regional brain volume reductions in preterm children with low risk for neurodevelopmental deficits. The significant interaction between cerebellar volume reduction and executive function and attention may suggest that even in preterm children at low risk can have different trajectories in the growth and development of overall brain structure.

RESUMO

Pulmonary hypertension may coexist with certain diseases in neonates. Iloprost inhalation is one of the treatments which cause selective pulmonary vasodilatation. Inhalation is not an easy way of drug administration in mechanically ventilated infants; as some exhibit desaturations during inhalation. Moreover, inhalation of drug requires cessation of mechanical ventilation, if patient is on high frequency oscillatory ventilation. We presented two patients with pulmonary hypertension; term baby with congenital diaphragmatic hernia and preterm baby with respiratory distress syndrome; who had iloprost instillation during mechanical ventilation treatment. Iloprost instillation was well tolerated with no side effects in the term patient with diaphragmatic hernia; whereas severe blood pressure fluctuations were observed in the preterm infant. This report may courage administration of iloprost in term neonates with resistant pulmonary hypertension.

RESUMO

BACKGROUND: Microcirculation is an important component of hemodynamic physiology. It can be assessed simply by clinical scores or by a variety of techniques including sidestream dark field (SDF) imaging and peripheral perfusion index (PI) measurements. Mode of delivery may have affects on microcirculation during transitional period. The aim of this study was to compare skin microcirculation in newborns born via vaginal delivery (VD) or cesarian section (C/S). METHODS: Term healthy newborns not requiring NICU admission were included. Vital signs were recorded. Skin microcirculation was determined by clinical scoring including capillary refill time, skin color, warmth of extremities, by SDF imaging where capillary density and microvascular flow is determined and by PI measurements where pulsatile and nonpulsatile capillary flow is measured. Assessments were done at 30 min and 24 h of life. Results were compared between VD and C/S groups and overtime. RESULTS: There were 12 newborns in VD group and 25 newborns in C/S group. No difference was observed in microcirculation assessments between groups. However VD group had increased hyperdynamic flow overtime. CONCLUSION: In healthy term newborns microcirculation does not seem to be affected by mode of delivery, however results may differ in sick or preterm newborns.

RESUMO

Aktas S, Ergenekon E, Ünal S, Türkyilmaz C, Hirfanoglu IM, Atalay Y. Different presentations of Cow's milk protein allergy during neonatal period. Turk J Pediatr 2017; 59: 322-328. Cow`s milk protein allergy (CMPA) is the most common cause of allergy occurring in the first year of life due to infant formula or breast-milk of mothers who are drinking cow`s milk or eating cow's milk products. Most children with allergic colitis are symptomatic in the first months, usually by 4 weeks. There are rare cases whom were sensitized prenatally and demonstrated symptoms in the first week, even in the first 2 days of life. The most common clinical sign of CMPA is bloody stool in a well-appearing infant. Gross bloody stool or fecal occult blood are also the common signs of necrotizing enterocolitis (NEC), especially in preterm infants with systemic instability. The treatment options are totally different so the clinician has to be very careful evaluating the patient. We report 5 preterm cases of CMPA, two of whom were siblings. Two of them presented with massive bloody stools and 3 of them presented with abdominal distension and fecal occult blood all of which were initially considered as NEC. Literature review of 20 cases with similar history is summarized as well.

RESUMO

BACKGROUND: Perfusion index (PI) is becoming a part of clinical practice in neonatology to monitor peripheral perfusion noninvasively. Hemodynamic and respiratory changes occur in newborns during the transition period after birth in which peripheral perfusion may be affected. Tachypnea is a frequent symptom during this period. While some tachypneic newborns get well in less than 6 h and diagnosed as "delayed transition", others get admitted to intensive care unit which transient tachypnea of newborn (TTN) being the most common diagnosis among them. We aimed to compare PI of neonates with TTN and delayed transition with controls, and assess its value on discrimination of delayed transition and TTN. METHODS: Neonates with gestational age between 37 and 40 weeks who were born with elective caesarian section were included. Eligible neonates were monitored with Masimo Set Radical7 pulse-oximeter (Masimo Corp., Irvine, CA, USA). Postductal PI, oxygen saturation and heart rate were manually recorded every 10 s for 3 min for two defined time periods as 10th minute and 1st hour. Axillary temperature were also recorded. Newborn infants were grouped as control, delayed transition, and TTN. RESULTS: Forty-nine tachypneic (TTN; 21, delayed transition; 28) and 30 healthy neonates completed the study. PI values were similar between three groups at both periods. There were no correlation between PI and respiratory rate, heart rate, and temperature. CONCLUSION: PI assessment in maternity unit does not discriminate TTN from delayed transitional period in newborns which may indicate that peripheral perfusion is not severely affected in either condition.

RESUMO

Pulmonary sequestration (PS) and pneumomediastinum are two rare clinical diseases. Pneumomediastinum was generally observed in infants either with diseased lungs or who were performed assisted ventilation or resuscitation following birth. It was reported in patients with existing ectopic thoracic kidney and laryngeal cysts however, no coexisting congenital lung anomalies were reported. Here, we report the pneumomediastinum occurred due the extralobar PS because of the mass effect of the lesion.

RESUMO

In this study, the authors report the results of a three-stage newborn hearing screening (NHS) program for well babies at the Gazi University Hospital (GUH) in Ankara between 2003 and 2013. GUH-NHS was performed by automated transient evoked otoacoustic emission (a-TEOAE) at the first and second steps and by automated brainstem audiometry (a-ABR) at the third step. The data were analysed to assess not only rate of congenital permanent hearing loss (CPHL), but also the effectiveness of the program during the years. A total of 18,470 well babies were tested. The data showed that coverage ratio for the GUH-born babies was increased and more outside-born babies (OBB) were admitted by time (means 84.31 and 11.28 %, respectively). Mean CPHL was found to be 0.26 %. Mean referral rate was decreased to 0.81 % by a-ABR from 2.16 % by a-TEOAE. Mean of missed cases in any stage of GUH-NHS was 4.88 %. It was seen that neither CPHL nor referral rate, but only ratio of missed ones presented increase in parallel to increment in OBB. This paper first presents that clinically acceptable screening procedures developed in GUH by time, and secondly higher rate of CPHL in Turkey than in the Western countries, and benefits of third stage screening by a-ABR because it prevented referral of 251 children (1.29 %) to the clinical tests. We think that this number is reasonably important regarding not only economical point of view, but also waiting lists in the audiology departments in a developing country, in which audiological service is still limited.

RESUMO

Non-invasive ventilation has been used increasingly in recent years to reduce the duration of endotracheal ventilation and its complications, especially bronchopulmonary dysplasia. Nasal continuous positive airway pressure and nasal intermittent positive pressure ventilation are the most common non-invasive modalities, and nasal high-frequency oscillatory ventilation (n-HFOV) is relatively new but it seems effective and feasible. We present three premature cases who were ventilated with n-HFOV with Neotech RAM Cannula as interphase. In two cases, we used n-HFOV with good results to prevent extubation failure, and in one case, we used it to avoid intubation with success. n-HFOV may be useful both in early times of respiratory failure and also to facilitate extubation particularly in patients with prolonged intubation.

RESUMO

BACKGROUND: Nutrition of very low-birth-weight newborns is important for a good physical and neurologic outcome. Body composition assessment, together with anthropometric measurements, is considered necessary to monitor adequate nutrition and growth. Objectives of this study were to assess body fat changes in newborns ≤32 weeks gestation by weekly skinfold thickness (SFT) measurements and to compare them with those of late preterm infants born at 34, 35, and 36 weeks once they reached 34, 35, and 36 weeks corrected age (CA). MATERIALS AND METHODS: Preterm infants ≤32 weeks gestation had SFT measured from 4 body sites, including biceps, triceps, and subscapulary and suprailiac regions, by a Holtain caliper starting from 48 hours of age at weekly intervals until 34, 35, and 36 weeks CA. The measurements were compared with those of late preterm controls born at 34, 35, and 36 weeks gestation. RESULTS: There were 37 preterm infants in the patient group. When reaching 34, 35, and 36 weeks CA, preterm infants had higher SFT values compared with controls in all body sites. Median and range of total SFT were 14.6 mm (9.6-18.9 mm) in patients and 11 mm (7.8-16.4 mm) in controls at 34 weeks CA, 15.5 mm (10.7-21.8 mm) in patients and 12.3 mm (7-17 mm) in controls at 35 weeks CA, and 16.4 mm (11.8-23.7 mm) in patients and 12.9 mm (7-17.8 mm) in controls at 36 weeks CA (P = .001 in all). No sex difference was observed at 34 and 35 weeks. CONCLUSION: These results show that preterm infants start accumulating excess fat even from early weeks of life. Careful assessment of growth by tools other than simple anthropometric measurements is essential to avoid future complications.

RESUMO

OBJECTIVE: To compare interleukine-10 (IL-10) and total antioxidant capacity (TAC) levels after breast milk storage by studying premature and term mothers' colostrum and mature milk and by analyzing those levels relative to gestational week. METHODS: Fifty-four colostrum and mature breast milk samples were collected from both premature and term mothers. The samples were divided into three groups based on the time of analysis: fresh milk, at +4 °C for 72 h, and at -20 °C for 14 d. The IL-10 and TAC levels were measured quantitatively. RESULTS: Fresh colostrum and mature milk had similar IL-10 levels. Term mothers' fresh-colostrum TAC levels were higher than their mature milk. The mature milk of the premature mothers' had higher TAC levels than that of term mothers. Storage did not affect the IL-10 levels of breast milk, but fresh milk antioxidant capacity halved after 72 h and 14 d. Colostrum IL-10 and TAC levels did not correlate with gestational week. Mature milk IL-10 levels did not correlate with gestational week, but TAC levels negatively correlated with gestational week (r: -0.61: p < 0.01). CONCLUSIONS: The milk stored for 72 h at +4 °C and for 14 d at -20 °C did not maintain the same TAC levels as the fresh samples. This should be considered especially for sick infants who need more antioxidant capability in neonatal units.

RESUMO

AIM: We aimed to evaluate the validity and reliability of the Infant Breastfeeding Assessment Tool (IBFAT), the Mother Baby Assessment (MBA) Tool, and the LATCH scoring system. SUBJECTS AND METHODS: Mothers who delivered healthy, full-term infants in the Obstetrics & Gynecology Service of Gazi University, Ankara, Turkey, between December 2013 and January 2014 and their infants were included in the study. Forty-six randomly selected breastfeeding sessions were monitored and scored simultaneously by three researchers (Raters 1, 2, and 3) using LATCH, IBFAT, and the MBA Tool. Researchers put the score sheets in an envelope in order to hide them from each other. The compatibility of the scores given by three researchers was assessed by statistical methods. RESULTS: We found positive and significant correlation coefficients between 0.81 to 0.88 for the total MBA score, between 0.90 to 0.95 for the total IBFAT score, and between 0.85 to 0.91 for the total LATCH score. Correlation coefficients testing these three tools ranged from 0.71 to 0.88, with the minimum value being noted for the correlation between LATCH and IBFAT scores and the maximum value being noted for the correlation between LATCH and MBA scores. CONCLUSIONS: We found positive and significant correlations between researchers' scores for 46 observations using the three assessment tools. This study showed that these above-mentioned tools were compatible for the assessment of the efficiency of breastfeeding.

RESUMO

The aim of this study was to see whether the scores of the Bayley Infant Neurodevelopmental Screener of 45 high-risk preterm infants (gestational age 26-37 wk) between the ages of 3 and 24 months predicted neurodevelopmental status at 7 to 10 years of age. Neurodevelopmental status of 45/122 preterm infants, grouped according to their gestational ages of 26 to 29, 30 to 32, and 33 to 37 weeks, were previously evaluated by Bayley Infant Neurodevelopmental Screener. The scores were categorized as low or high-moderate. Verbal and performance scores of Wechsler Intelligence Scale for Children-Revised (WISC-R) of those patients were assessed between 7 and 10 years. The patients with high-moderate-risk scores of Bayley Infant Neurodevelopmental Screener at all times, regardless of their gestational age, had lower performance, verbal, and total scores of WISC-R than those of who had low Bayley Infant Neurodevelopmental Screener risk scores. High-moderate risk score of Bayley Infant Neurodevelopmental Screener at 7 to 10, and 16 to 20 months, of all patients especially showed good prediction for identifying lower verbal and performance scales. For 7 to 10 months, verbal scale: positive predictive value = 92.3%, negative predictive value = 44.4%, sensitivity = 70.58%, and specificity = 80%; performance scale: positive predictive value = 100%, negative predictive value = 30%, sensitivity = 68.18%, and specificity = 100%. For 16 to 20 months, verbal scale: positive predictive value = 90%, negative predictive value = 37.5%, sensitivity = 64.3%, and specificity = 80%; performance scale: positive predictive value = 90%, negative predictive value = 12.5%, sensitivity = 56.3%, and specificity = 50%. Bayley Infant Neurodevelopmental Screener shows good prediction of later verbal and performance scores of Wechsler Intelligence Scale-Revised for Children as early as 7 to 10 months, which gives us the opportunity to start early intervention.

RESUMO

Intravenous Immunoglobulin G (IVIG) therapy has been used as a component of the treatment of hemolytic disease of the newborn. There is still no consensus on its use in ABO hemolytic disease of the newborn routinely. The aim of this study is to determine whether administration of IVIG to newborns with ABO incompatibility is necessary. One hundred and seventeen patients with ABO hemolytic disease and positive Coombs test were enrolled into the study. The subjects were healthy except jaundice. Infants were divided into two groups: Group I (n = 71) received one dose of IVIG (1 g/kg) and LED phototherapy whereas Group II (n = 46) received only LED phototherapy. One patient received erythrocyte transfusion in Group I, no exchange transfusion was performed in both groups. Mean duration of phototherapy was 3.1 ± 1.3 days in Group I and 2.27 ± 0.7 days in Group II (p < 0.05). Mean duration of hospital stay was 5.34 ± 2.2 days in Group I and 3.53 ± 1.3 days in Group II (p < 0.05). Mean duration of phototherapy was 4.0 ± 1.5 days and 2.73 ± 1.1 days in double and single doses of IVIG respectively, and this was statistically significant (p < 0.05). IVIG therapy didn't decrease neither phototherapy nor hospitalization duration in infants with ABO hemolytic disease. Meticulus follow-up of infants with ABO hemolytic disease and LED phototherapy decreases morbidity. IVIG failed to show preventing hemolysis in ABO hemolytic disease.

RESUMO

Newborns are exposed to a considerable number of painful stimuli. This study is aimed to investigate the effects of 30% glucose solution and nonnutritive sucking on pain perception during venipuncture. Twenty-five term infants were randomized as receiving 30% dextrose (group 1) or sterile water (group 2). Neonatal Infant Pain Scale scores, skin conductance algesimeter recordings, and near-infrared spectroscopy measurements were recorded during the procedure. Neonatal Infant Pain Scale and skin conductance algesimeter results were decreased in both groups from that during venipuncture to after the procedure. Group 1 had lower Neonatal Infant Pain Scale scores compared with group 2 after venipuncture, different from the skin conductance algesimeter, where no difference was observed between groups. In group 1, cerebral blood volume increased after venipuncture. Glucose does not attenuate the Neonatal Infant Pain Scale score and skin conductance algesimeter index during venipuncture, but it leads to a lower Neonatal Infant Pain Scale score after venipuncture unlike the skin conductance algesimeter index, which was not lowered.
