Abstract
Purpose :
This follow-up study was designed to confirm that music as adjuvant method can relieve subjects’ anxiety and pain during LASIK, and how influence of music is affected by subjects’ anxiety and attitude towards pain.
Methods :
Fifty naïve subjects planning for LASIK were randomized into three sequence groups according to three different ordering with music-listening (M), news-listening (N) and no sound (control, C), to minimize bias. First, subjects filled in coping strategy questionnaire to measure anxiety and catastrophized of pain state. We measured pain tolerance time (PT), pain attention (PA) in each three treatments (Music, News, Control) through cold-pressor pain task. Ice water was maintained at 2~3 degrees Celsius, two researchers recorded subjects’ PT using stopwatch, subjects recorded their PA using visual analog scale with range of 0 to 10. The high degree of focus pain means closer to 10. Subjects were divided into two groups: high score and normal group depending on coping strategy questionnaire score. Sample size was calculated with 5% significance level and 80% power.
Results :
Statistical analysis was performed with SPSS v 23. Subjects’ average age was 25.7 (SD=±2.9, Range= 20~34) of which 48% were male and 52% female. Average PT for C, N, M were 14.87, 16.33, 20.45 secs and PA were 7.01, 6.46, 5.90 respectively. Result of F-test showing the difference in average PT and PA among 3 sequence groups was significant (p= 0.0001, p= 0.0019 respectively). Bonferoni post hoc confirmed that M was most effective compared to C or N on PT (p<0.001). Bonferoni post hoc confirmed that M was more effective than C (p=0.012), and not significant between M and N (p=0.20). Especially, there were different tendencies between catastrophized high score and normal group, PA would be actively distracted under music-listening compared to news and control in high score group (p= 0.01). However, differences were not discovered of PA in music compared with news and control in the normal group.
Conclusions :
Anxiety and attitude towards pain level should be considered in LASIK as well as ophthalmic surgery which accompany pain. Although it was also confirmed that music has the most efficacy to control pain, the usage of music as adjuvant method should depend on subjects’ traits.
