The current study aimed to monitor how blood acid-base status and vital parameters, including rectal temperature (RT), heart rate (HR), respiratory rate (RR), change in lambs and goat kids over the first week of life. Ten female Comisana lambs and 10 female Maltese goat kids were enrolled in the study. For each animal, RT, RR, HR measurement and blood sampling were daily performed from birth for a 7 day period (Day1–Day7). RR and HR decreased throughout study period (P < 0.05) in both species; pH showed lower values at Day1, Day2 and Day3 compared to Day6 and Day7 in lambs. Increased pO2 values were found in lambs and goat kids during the first 5 days after birth (P < 0.05). Lambs and goat kids showed higher pCO2 values during the first hours of life than the rest of study period (P < 0.05). Higher HCO3 values were found at Day1 and at Day4 compared to the rest of study period in lambs (P < 0.05). RT, RR, HR and pCO2 displayed a significant negative correlation with time in both lambs and goat kids, whereas, the pH values resulted positively correlated with time. In both species RT values were negatively correlated with pH and pO2, and positively correlated with pCO2; RR and HR resulted negatively correlated with pH and pO2, and positively correlated with pCO2. The observed changes reflect the physiological adjustments likely to occur in a newborn animal following transition from the controlled uterine environment to the free-living state and emphasize the importance of a deep knowledge on these physiologic parameters for an early diagnosis of risk factors or any situations that involve an high-risk newborn.

出生后前7天内羔羊和山羊羔儿童血酸碱状态和重要参数的每日动态变化

当前的研究旨在监测出生后第一周的血液酸碱状态和生命参数,包括直肠温度(RT),心率(HR),呼吸频率(RR),羔羊和山羊羔的变化。这项研究招募了十只科米萨纳(Comisana)羔羊羔羊和十只马耳他山羊(Maltese)孩子。对于每只动物,从出生开始每天进行为期7天(第1天至第7天)的RT,RR,HR测量和血液采样。在整个研究期间,两种物种的RR和HR均降低(P <0.05)。与羔羊的第6天和第7天相比,第1天,第2天和第3天的pH值较低。在出生后的前5天,羔羊和山羊羔的pO 2值升高(P <0.05)。羔羊和山羊羔的pCO 2更高出生后头几个小时的学习值高于其余时间(P <0.05)。更高HCO 3 -在第一天,并在第4天,发现值相比研究期间的羔羊中的其余部分(P <0.05)。在羔羊和山羊羔羊中,RT,RR,HR和pCO 2与时间呈显着负相关,而pH值与时间呈正相关。在两种物种中,RT值与pH和pO 2呈负相关,与pCO 2呈正相关; RR和HR与pH和pO 2呈负相关,与pCO 2呈正相关。观察到的变化反映了从受控子宫环境过渡到自由生活状态后新生动物可能发生的生理调节,并强调了对这些生理参数的深入了解对于早期诊断危险因素或任何情况的重要性。涉及高危新生儿。
