Objective: Adequate control of postoperative pain continues
to pose a challenge for the surgeon. Music therapy with guided imagery (MT/GI)
has been shown to ameliorate symptoms and perception of pain. The objective of
this study was to evaluate the effect of MT/GI on postoperative pain, anxiety
and analgesic use.
Methods: Prospective randomized study of 81 patients with
major gynecologic procedures. Study participants were randomized to two
intervention groups: MT/GI plus analgesic (MT/GI group, n = 44) vs. analgesic
only (control group, n= 37). Information was recorded before surgery and at pre
and post intervention on days 1, 2 and 3 post surgery. It included: pain and
anxiety (assessed by using the Visual Analogue Scale, VAS); medication use in
equivalent morphine dosages; pulse and mean arterial blood pressure (MAP).
Statistical analyses included within and between group comparisons of the above
parameters and also of the pre and post intervention differences in those
parameters. Statistical techniques included chi-square analysis, paired and
independent sample t-tests, Wilcoxon signed rank tests and Mann-Whitney tests.
Results: There were no significant differences between
intervention and control groups with respect to potential confounders such as
age, marital status, procedure performed, and smoking; past history of surgery
or medical conditions; and pre-operative pain, anxiety, pulse and MAP. Within
the MT/GI group, at each assessment day, there was a significant decrease
(p-value < 0.05) from pre to post intervention with respect to pain, anxiety,
medication use, pulse and MAP. Mean decreases in these parameters were
significantly higher in the MT/GI group when compared to the control group at
each assessment day. In addition, 100% of the patients in the MT/GI group said
they would recommend music therapy to other patients and would use it again for
control of their postoperative pain.
Conclusion: Music therapy and guided imagery play a
significant role in decreasing pain and anxiety in patients undergoing
gynecological surgery. It also decreases analgesic intake for control of pain.
This may translate into decreased side effects from narcotic use with a better
quality of life for patients in the immediate postoperative period.
