Pain reduction interventions during neonatal circumcision.
The purpose of this study was to determine the effect of some noninvasive pain reduction interventions on pain in 121 neonates undergoing unanesthetized circumcision. Subjects were randomly assigned to one of six groups: classical music, intrauterine sounds, pacifier, music and pacifier, intrauterine sounds and pacifier, or control (no nurses present and no pain reduction interventions used). Physiological variables that were monitored were heart rate, rhythm, dysrhythmias, blood pressure, transcutaneous oxygen (tcpO2), rate pressure product, and behavioral state, measured during 14 circumcision steps. Over the 14 steps, 42% of the heart rates, 78% of the systolic blood pressures (SBP), 30% of the diastolic blood pressures (DBP), and 81% of the tcpO2 pressures were abnormal. Few significant differences were found among any of the steps. SBP and DBP differed significantly between groups during two of the noninvasive steps; and tcpO2 differed significantly during six steps.
Pain reduction during neonatal circumcision.
PURPOSE: To determine the effect of two comfort interventions during unanesthesized circumcision on neonatal pain. METHODOLOGY: Fifty-eight neonates were randomly assigned to one of three intervention groups. Eighteen control infants received routine care, 15 infants had music played, and 15 infants had a tape of intrauterine sounds played. During circumcision, monitors measured cardiac rate, rhythm, blood pressure, and transcutaneous oxygen. Pain was measured by analysis of videotaped facial expressions using Izard's Maximally Discriminative Facial Movement Coding System (1983). RESULTS: Mean heart rate was above normal limits during all steps of the circumcision for the control group and during some of the steps for the other two groups. Facial expressions analyzed showed all three groups had pain much more than any other emotion during the procedure. CONCLUSIONS: The two interventions were unable to offset the effects of circumcision pain.
