ABSTRACTObjective: To assess the impact of age, gender, type of lesion, surgical time and technique on the intensity of pain immediately after inguinal repair surgery.
Design: Prospective, longitudinal, descriptive.
Statistical analysis: Student t test and Kolmogorov-Smirnov test.
Material and Method: Studied variables were: age, gender, type of injury, repair technique used, and surgical time. An analogic verbal scale, with values from 0 to 10 was used to measure pain, where 0 is no pain and 10 is the maximal tolerable pain. We performed two measurements, the first at 3 h after surgery, once the effect of the epidural block had waned and the second was performed on the next day of surgery, at 07:00 hours, that is, between 14 and 21 hours after surgery.
Results: We evaluated 210 cases in 21 months, men:women ratio was 4 to 1, most lesions corresponded to Nyhus III B (35%) and Nyhus II (32%), 180 patients were operated with a tension-free technique using prosthetic material; no prosthetic material was used in the remainder 30 patients. Pain in the first measurement was distributed along the whole scale, concentrating at intensities of 3 to 5 in 74.8% of the patients, decreasing markedly in the second measurement, comprising 82.8% of the patients in the 1 to 4 pain intensity range. We found intensity variations between the techniques (with and without tension) used, and among age, gender, and type of injury; however, these variations had no statistical significance.
Conclusion: Inguinal repair is a procedure in which a high degree of pain tolerance is reported by patients. According to the results of the present work, average pain intensity reaches the mid or lower values of the scale used to measure pain, independently from the repair, the type of injury, age, or gender.
