Medial olivary complex reflex in term newborns with hyperbilirubinemia.

OBJECTIVE: This study aimed to compare the integrity of the efferent auditory pathways of newborns that had high hyperbilirubinemia levels and required treatment due to these and healthy newborns. METHODS: Term-born (37 weeks or later) infants that were brought to the Newborn Polyclinic of the Baskent University Hospital were included in the study. The study included a total of 84 infants including healthy newborns (n = 42) and those that had jaundice and were receiving phototherapy (n = 42). After conducting a general otorhinolaryngology examination on all newborns included in the study, Transient Otoacoustic Emission (TEOAE) test was carried out in the absence and presence of contralateral noise. The obtained contralateral suppression values were compared between the two groups. RESULTS: In the TEOAE test, the responses obtained at 1 kHz in the newborns receiving phototherapy were found to be lower. The difference between the groups was significant (p = 0.038). The rates of suppression presence at 2 kHz, 2.8 kHz and total OAE were found significantly higher (p < 0.05) in the group not receiving phototherapy. Among the phototherapy-receiving infants, the hyperbilirubinemia levels of the infants in whom suppression was obtained in the contralateral suppression test did not show a statistically significant difference in comparison to those in whom suppression was not obtained (p > 0.05). CONCLUSION: Based on the obtained data, hyperbilirubinemia may have a disruptive effect on the efferent auditory system in newborns. Consequently, we are of the opinion that, in addition to hearing screening in risky newborn infants, a MOC suppression test would be useful.

Hemolytic anemia caused by non-D minor blood incompatibilities in a newborn.

Hyperbilirubinemia is one of the most widely seen cause of neonatal morbidity. Besides ABO and Rh isoimmunization, minor blood incompatibilities have been also been identified as the other causes of severe newborn jaundice. We report a newborn with indirect hyperbilirubinemia caused by minor blood group incompatibilities (P1, M, N, s and Duffy) whose hemolysis was successfully managed with intravenous immunoglobulin therapy. A thirty-two gestational weeks of preterm male baby became severely icteric on postnatal day 11, with a total bilirubin level of 14.66 mg/dl. Antibody screening tests revealed incompatibility on different minor groups (P1, M, N, s and Duffy (Fya ve Fyb)). On postnatal day thirteen, the level of bilirubin increased to 20.66 mg/dl although baby was under intensive phototherapy. After the administration of intravenous immunoglobulin and red blood cell transfusion, hemoglobin and total bilirubin levels became stabilised. Minor blood incompatibilities should be kept in mind during differential diagnosis of hemolytic anemia of the newborn. They share the same treatment algorithm with the other types hemolytic anemia. New studies revealed that intravenous immunoglobulin treatment in hemolytic anemia have some attractive and glamorous results. It should be seriously taken into consideration for treatment of minor blood incompatibilities.

Acupressure at BL60 and K3 Points Before Heel Lancing in Preterm Infants.

CONTEXT: Acupressure is an ancient Chinese healing art. In this pain-relieving method, the fingers are used to press key acupuncture points on the skin surface that stimulates the body׳s regulatory processes. OBJECTIVE: The aim of this study was to investigate the effect of acupressure at Kun Lun (UB60) and Taixi (K3) points for pain management in preterm infants prior to heel lancing for blood collection. DESIGN: This was a prospective, randomized controlled study. SETTING: The study setting was the neonatal intensive care unit at Baskent University Hospital in Turkey. PATIENTS: A total of 32 preterm infants between 28 and 36 weeks׳ gestational age were randomly assigned to one of two groups: an acupressure group (n = 16) or a control group (n = 16). INTERVENTION: In the acupressure group, immediately before the heel prick, acupressure was applied for three minutes at UB60 and K3 points. MAIN OUTCOME MEASURES: A behavioral pain score was determined using the Premature Infant Pain Profile (PIPP) scale. RESULTS: There were no significant differences between the groups with respect to gestational age, birth weight, sex, mode of delivery, age at time of procedure, weight at time of procedure, or PIPP score. Mean duration of procedure and mean duration of crying were both shorter in the acupressure group (both P = .001). CONCLUSIONS: Applying acupressure at the BL60 and K3 points before heel lancing was associated with shorter procedural time and shorter duration of crying in preterm infants.

Evaluation of peripheral perfusion in term newborns before and after Yintang (EX-HN 3) massage.

OBJECTIVE: To identify how acupressure on the acupoint Yintang (EX-HN 3) impacts oxygen saturation, pulse rate, and peripheral perfusion in term-born infants without underlying disease. METHODS: Infants born between weeks 37 and 42 of gestation were included in this study. The polyclinic's neonatology room was noise-controlled and made half-dark to prevent the perfusion index from being confounded. A pulse oximeter was linked to the baby's left lower extremity. Acupressure was applied on Yintang (EX-HN 3) for 30 s clockwise, held for 30 s, and then acupressure was applied for another 30 s counterclockwise. The baby's SaO2, pulse rate, and perfusion index were recorded for each minute before and after acupressure. RESULTS: When pre- and post-acupressure pulse rate values were compared, a significant decrease in pulse rate values after acupressure application was observed. When pre- and post-acupressure oxygen saturation values were compared, a significant increase in post-acupressure oxygen saturation was observed. In addition, peripheral perfusion increased significantly after acupressure. CONCLUSION: Acupressure application has been used in traditional medicine for many years. However, it is not yet widely used in modern medicine. This study shows the impact of acupressure on neonatal skin perfusion, oxygen saturation, and pulse rate.

Comparison of cervical vestibular evoked myogenic potentials between late preterm and term infants.

Recent investigations have shown that late preterm infants have increased risk for attention deficit hyperactivity disorder, neurosensory impairment, and emotional, behavior and learning problems. Vestibular evoked myogenic potential (VEMP) abnormality may partly contribute to these problems. Our aim was to measure VEMP in late preterm infants and to compare the findings between late preterm and term infants. Seventeen late preterm infants (mean gestational age: 35.11 weeks +/- 0.78) postnatal aged 8 weeks and 17 full-term (mean gestational age: 38.05 weeks +/- 0.96) infants postnatal aged 4 weeks underwent cervical (c)VEMP test without sedation. Mean latencies of p13 were calculated in all study subjects. cVEMPs were elicited in all late preterm and term infants. Mean latencies of p13 in late preterm and term infants were 14.53 and 13.34 ms, respectively. Mean latencies of n23 were determined as 23.18 ms and 19.92 ms for late preterm and term infants, respectively. There were statistically significant differences between late preterm and term infants for latency of p13 (p < 0.001) and latency of n23 (p < 0.000). Abnormal VEMP results might be related to a delay in the maturation of the sacculocollic pathways in late preterm infants.

Acupuncture in preterm babies during minor painful procedures.

OBJECTIVE: To evaluate analgesic effects of acupuncture in preterm neonates during minor painful procedures. METHODS: Ten preterm neonates requiring heel prick for blood gas analysis were enrolled in the study, which had a crossover design. Oxygen saturation, systolic and diastolic blood pressure, respiratory rate, heart rate, and crying duration were recorded before and after heel prick. Babies were given expressed breast milk before each procedure. Patients were randomly assigned to receive acupuncture or not, and the groups were crossed over on the following day, so that patients who had received acupuncture received only breast milk, and the previous breast milk only group received both acupuncture and breast milk. The neonatal infant pain scale (NIPS) was used for pain evaluation. RESULTS: Crying duration and NIPS pain scores during heel prick were lower in the neonates who had received acupuncture. CONCLUSION: Acupuncture is an effective method for the treatment of pain in neonates.
