Comparing the behavioral and physiological signs of pain between the first and the second tries of the aggressive procedures in neonates admitted to Ramhormoz hospital in 2017

Pain monitoring of newborns during aggressive interventions and painful procedures has often been limited to the first time of the invasive procedures, and pain monitoring during the repetition of procedures has been neglected. This research aims to determine and compare the behavioral and physiological signs of pain in newborns during the first and the second consecutive invasive procedures. In this quantitative and descriptive study, 100 infants were selected conveniently from Mother Hospital of Ramhormoz city based on the inclusion criteria. Data was collected by demographic questionnaire, standard infant-infant pain assessment tool, and objective measurement tools during five months. Data analysis was done with descriptive statistics and t-test at the error level of 0.05. The results showed that in the first round of diagnostic and therapeutic measures, the most reactions to the painful procedure were frowning (97%), leg flexion/extension (96%) and arm flexion/extension (94%) and in the second round the most reaction was in the form of no change in face (99%), normal breathing pattern change (96%), and flexion/extension of legs and arms (96%). The average number of heart rate and breathing during the procedure was increased in both the first and the second time compared to before the procedure. The average score of pain behavior symptoms in the second round was significantly higher than the first round. It is necessary for all nurses to evaluate the symptoms of pain during repeated interventions in order plan for controlling and reducing the pains in both times of performing consecutive procedures
