| Popis: | Neonatal physiology has peculiarities inherent to the age group. The objective of this study was to monitor the systemic arterial pressure in lambs during neonatal period. We used 20 Ile de France lambs, from birth and at 7, 14, 21, 28 and 35 days of life. The following parameters were analyzed: heart rate (HR), systolic (SBP), diastolic (DBP), and average blood pressure (ABP) by oscillometric method petMAP™, and SBP with Doppler. Invasive pressure validated indirect methods with the average 101.52 ± 12.04 mmHg. The averages with petMAP™ were as follows: HR (156.38 ± 37.46 bpm); DBP (63.80 ± 11.14 mmHg); ABP (81.58 ± 11.83 mmHg); SBP (112.48 ± 15.68 mmHg) and SBP by Dobler (90.27 ± 12.11 mmHg). There was significant difference in HR and blood pressure among the moments. Indirect methods differ between each other in 12.30 mmHg (overestimation of 11%). Comparing with the invasive methods, both overestimated values of 4% and 16% in PAS, respectively, for Doppler and petMAP™. The results showed that the Doppler method has established a good relationship with the invasive one being useful for gauging the SBP. The oscillometric method requires larger studies to be used in small ruminants. Keywords: Doppler; lamb; neonatal period; oscillometric; systemic blood pressure. |
