BACKGROUND AND AIM: In this study, it was aimed to compare the effect of Transversus abdominis plane (TAP) block application on postoperative analgesia quality and patient satisfaction with intrathecal morphine application.
METHODS: Clinical Trials number (ClinicalTrials.gov ID: NCT02983383) was also taken before the study.The calculation of sample size was done with G-Power program The effect size-F ratio was estimated as 0.833 based on previous studies and the assumption of equal group numbers. For 90%, statistical power, 5% type I error rate and 90% confidence interval, required sample size was calculated as 32 patients for per group..70 patients were randomized by lottery method and divided into two groups as spinal anesthesia + TAP block (TAP block group, n = 34) and spinal anesthesia + intrathecal morphine group (ITM group, n = 36). Patients' age, BMI values, VAS values at 0,2,6,12,18 hours, and patient satisfaction scored by QUIPS at 24 hours were evaluated.
RESULTS: The mean age of the TAP group was 32.52 ± 6.50 and 30.11 ± 5.62 in ITM group. There was no statistically significant difference between groups. There was no statistically significant difference in terms of visual analogue scale values at 0, 2, 6, 12, 18 hours ( p> 0.05). The patients were evaluated for mean, maximum and minimum pain values at 24 hours postoperatively, which was no difference between the groups (respectively, p = 0.836, p = 0.309, P = 0.745,). There was a significant difference between the groups in terms of patient satisfaction scores (p=0.019). When the factors affecting patient satisfaction were evaluated postoperatively, feeling fatigue after the surgery (r:-0.811, p=0.001) and postoperative complications such as nausea, vomiting, and itching (r:-0.831, p=0.001) were found to affect patient satisfaction negatively.
CONCLUSIONS: Due to low complications rates, TAP block is an effective application for postoperative analgesia management in varicocele operations, which increases patient satisfaction postoperatively.
