Parâmetros hemogasométricos e equilíbrio ácido-básico de cabritos nascidos de partos normais

Abstract

RESUMO.-A adaptação à vida extra-uterina é período críti-co para o recém-nascido. Inúmeras alterações ocorrem em diferentes sistemas e órgãos, incluindo a função respirató-ria e o equilíbrio ácido-básico. O presente trabalho objetivou constatar a ocorrência de acidose em cabritos recém--nascidos e obter parâmetros gasométricos e ácido-básicos dos mesmos, até as 24 horas de vida. Para tanto, foram utilizados 33 cabritos, sem distinção de sexo. Amostras san- The extra-uterine life adaptation is a critical period for the newborn. Several changes occur in different organ systems including respiratory function and acid-base balance. The aim of this study was to hypothesize the occurrence of acidosis in newborn kids and obtain blood gas and acid-base parameters of kids in the first 24 hours of life. For this, 33 goat kids of both sexes were used. The blood samples were collected by jugular venipuncture immediately after birth, 5, 10, 15 minutes and 24 hours of life. The blood pH, oxygen partial pressure (pO 2 ), carbon dioxide partial pressure (pCO 2 ), total carbon dioxide (TCO 2 ), bicarbonate concentration (HCO 3 ), base excess (BE) and oxygen saturation (SO 2 ) were determined with a portable blood gas analyzer. Significant differences were observed between the moments in all variables of the kids blood gas values. The newborn kids had respiratory acidosis during the immediate post-partum period, normalizing at 24 hours of life.INDEX TERMS: Blood gas, acid-base balance, acidosis, pH, newborn, goats. guíneas foram colhidas por venopunção jugular, imediatamente após o nascimento, aos cinco, dez e 15 minutos, e às 24 horas de vida, para determinação do pH, pressão parcial de oxigênio (pO 2 ), pressão parcial de dióxido de carbono (pCO 2 ), dióxido de carbono total (TCO 2 ), concentração de bicarbonato (HCO 3 ), excesso de bases (BE) e a saturação de oxigênio (sO 2 ) utilizando-se analisador portátil de gases sanguíneos. Observaram-se diferenças significativas entre os momentos nos valores gasométricos dos cabritos em todas as variáveis estudadas. Os cabritos recém-nascidos apresentaram acidose respiratória no período pós-parto imediato, normalizando-se às 24 horas de vida. TERMOS DE INDEXAÇÃO: Hemogasometria, equilíbrio ácido-bá-sico, acidose, pH, neonatos, caprinos. INTRODUÇÃOAs prevalências de mortalidade perinatal de caprinos são bastante variáveis. Estudos indicam perdas de 10-60% em sistemas extensivos de criação, e de 8-17% em criações intensivas. Os prejuízos decorrentes da mortalidade perinatal incluem a perda dos recursos investidos nas matrizes,

Evaluation of the effect of birth type on blood gas and Apgar scores in newborn kids

“…The level of hypoxia and acidosis may vary depending on the onset of spontaneous breathing and the time it takes for the mother to completely leave the fetal bloodstream (Reece, 2004). It has been reported that there is no significant difference in pH, pCO2, pO2 and HCO3 levels at 0 and 24 hours in calves with dystocia compared to calves with eutocia (Feitosa et al, 2012). In another study, it was found that foals and lambs born as a result of dystocia had low pH and HCO3 levels, and the improvements in blood gases were similar on the 1st day, according to those results, it was reported that in foals born as a result of dystocia there were negative effects on blood gases (Aydoğdu et al, 2018;Kimura et al, 2017).…”

“…Newborn lives are sensitive to adverse environmental conditions and perinatal diseases, and their metabolic status is highly variable (Piccione et al, 2007). During this period, numerous changes occur in different systems and organs, including respiratory function and acid-base balance (Camargo et al, 2012). Newborns may die due to trauma and prolonged hypoxia during delivery (Feitosa et al, 2012).…”

Newborns may die due to trauma and prolonged hypoxia during delivery (Feitosa et al, 2012). Intrapartum hypoxia is of great importance in terms of newborn losses due to dystocia (Scott, 2006).…”
