[Effect of preoperative preoperative visualization therapy on postoperative outcome after inguinal hernia surgery and thyroid resection].
This randomized controlled trial aims to evaluate the influence of preoperative relaxation techniques on postoperative outcomes. From January 1997 to June 1998 208 patients were operated on for primary inguinal hernia or goiter. The patients were randomized into two groups: Group A (n = 103) underwent the surgical treatment with a preoperative visualization therapy. Group B (n = 105) underwent the surgical treatment without a preoperative therapy. Patients with age under 18 years, ASA-status IV-V, recurrent inguinal hernia or recurrent goiter and malignant neoplasms were excluded from the study. There were no differences in age, sex, duration of the operation, training of the surgeon, and preoperative blood parameters between the two groups.


RESULTS
During the postoperative follow-up we observed more hematomas (group A with visualization therapy: 30.3%, group B without visualization therapy: 44.4%) as well as more pain (group A: 4.2, group B: 5.2) and analgesic consumption (group A: 59.7 mg Tramadol HCL, group B: 72.5 mg Tramadol HCL) in group B (p < 0.05). There were no significant differences in infections, nausea, hypocalcemia, tetania, recurrent nerve palsy, fever.


CONCLUSIONS
Preoperative visualization therapy reduces significantly the number of postoperative hematomas after inguinal hernia repair. Furthermore a decrease of analgesic requirements after surgical treatment was observed.
