Abstract
ABSTRACT Objective To explore the effects of intraoral pressure on colostrum intake. Methods Healthy women with full-term infants were admitted in the study after birth. Intraoral pressure was detected before and after the mothers’ onset of lactation by a pressure sensor during a breastfeeding session. Colostrum intake was measured by weighting the infant before and after breastfeeding. The onset of lactation was confirmed by the mothers’ perceptions of sudden breast fullness. Results The newborns’ peak sucking pressure was 19.89±7.67kPa before the onset of lactation, dropping to 11.54±4.49kPa after mothers’ onset of lactation (p<0.01). The colostrum intake was 4.02±4.26g before the onset of lactation, and 11.09±9.43g after the onset of lactation. Sucking pressure was correlated with the amount of colostrum intake before and after the onset of lactation after adjusting the confounding factors. Conclusions The newborns’ intraoral pressure at early stage played a predominant role in colostrum intake. It is recommended to initiate breastfeeding immediately after the birth to take advantages of the active and robust sucking response. It is valuable to understand the importance that the sucking pressure plays in the colostrum intake and active immunity achievement during the first several days after birth.
Highlights
MethodsHealthy women with full-term infants were admitted in the study after birth. Intraoral pressure was detected before and after the mothers’ onset of lactation by a pressure sensor during a breastfeeding session
Women presenting the following conditions were excluded: (1) breastfeeding contraindication; (2) infant was transferred to newborn intensive care unit; (3) breast surgery/injury history; (4) flat nipple; (5) maternal smoking; (6) pregestational Body Mass Index (BMI)>27kg/m2; (7) cesarean section or vaginal delivery by obstetric forceps or vacuum extractor; or (8) other conditions impeded the normal onset of lactation, such as diabetes, hypertension, hypothyroidism, hypopituitarism, and postpartum haemorrhage
Maternal pre-gestational Body Mass Index (BMI), BMI gain during pregnancy, duration of labor, oxytocin administration, episiotomy, newborn birth weight, gender, gestational age, first breastfeed, sucking frequency, sucking duration, infant breastfeeding performance (Infant Breastfeeding Assessment Tool, IBAT), formula supplement, pacifier usage, time from birth to first intraoral pressure measurement, maternal pain, fatigue, and EPDS scores were collected through medical records or face-to-face interviews carried out by our trained nursing staff [17,18]
Summary
Healthy women with full-term infants were admitted in the study after birth. Intraoral pressure was detected before and after the mothers’ onset of lactation by a pressure sensor during a breastfeeding session. A pressão de sucção foi correlacionada com a quantidade de ingestão de colostro antes e após o início da lactação depois de terem sido feitos ajustes dos fatores de confusão. Negative intraoral pressure is the main driving force in drawing milk out of the breast during breastfeeding in the infant with maturation. Early initiation of breastfeeding has been proven to decrease neonatal death [8,9,10] It is not clear if negative intraoral pressure plays a role in colostrum. This study compared infant negative intraoral pressures before and after the onset of lactation, and further explored the role of intraoral pressures in colostrum intake in early breastfeeding
