Abstract:
Objective:To study the trends and ranges of blood pressure in extremely premature infants (EPIs) during the first 7 days after birth.Methods:From January 2016 to December 2020, EPIs born in our hospital were retrospectively analyzed. Their blood pressure were monitored using umbilical arterial catheters and no patients needed anti-hypotension treatment. The clinical data of the infants and their mothers, blood pressure data during the first 7 days after birth, clinical outcomes and complications were collected. The trends of blood pressure in untreated EPIs were analyzed and the blood pressure ranges of EPIs of different gestational ages (GA) were established.Results:A total of 145 cases of EPIs were included and their systolic pressure, diastolic pressure and mean blood pressure showed upward trends during 2~168 h after birth ( P<0.001). The diastolic pressure increased significantly within 24 h after birth ( P<0.05), systolic pressure and mean blood pressure increased significantly within 72 h after birth ( P<0.05). Blood pressure increased with age and GA. Conclusions:The blood pressure of EPIs will increase spontaneously during 7 days after birth. The ranges of blood pressure are measured for infants with different GA to provide clinical evidence for blood pressure management of EPIs during early postnatal period.
