Objective To investigate the influencing factors of
pain and the changes of
vital signs in
newborn infants.
Methods Forty two
newborn infants were rated by the behavioral scale of
acute pain in
newborn infants. The scores of
pain were compared among
infants with different
gender,
gestational age,
birth weight,
birth age,type of
puncture and whether by vaginal
birth or not. At the same
time,the
respiration rate,
heart rate,
blood pressure and
oxygen saturation (SO2)were dynami-cally recorded by the multi-function monitor in the process of
puncture. Results The average score of
pain was 7.6. There was no significant difference among
newborn infants with different
gender,
gestational age,
birth weight and type of
puncture(P> 0.05),while significant differences among
infants with different
birth age and whether by vaginal
birth or not (P=0.015 and 0.043 respectively). In the process of
puncture,the SO2 was significantly decreased,while the
respiration rate,
heart rate,sys-tolic and diastolic
blood pressure were significantly increased. Conclusions
Pain is prevalent in
newborn infants and accom-panied by obvious changes of
vital signs. The means of
childbirth and
birth age have significant influence on the neonatal
pain. It is suggested to pay close
attention to the neonatal
pain and take effective interventions.
