Purpose The aim of this study is to compare the effects of preoperatively administered erector spinae plane (ESP) block, applied either before or after anesthesia induction, on recovery quality, anxiety, and patient satisfaction in patients undergoing elective lumbar disk hernioplasty. Design Prospective, randomized, controlled, single blind study. Methods This study involved 100 patients aged 18 to 65 years with American Society of Anesthesiologists physical status I to III who underwent elective single-level lumbar disk hernioplasty. Participants were allocated into two groups: the group receiving the block after anesthesia induction (intraoperative) was named group I, and the group receiving the block before anesthesia induction (preoperative) was named group P. Preoperative demographic data were gathered for all patients, and State-Trait Anxiety Inventory (STAI-I and STAI-II) questionnaires for evaluating anxiety, as well as Quality of Recovery-40 (QoR-40) questionnaires for assessing postoperative recovery, were administered. Findings Postoperative QoR-40 data were significantly higher in group I compared with group P (P = .02). However, the minimal clinically important difference was determined to be minimally clinically significant. One of the subparameters of the QoR-40 score, emotional status scores, was found to be statistically significantly higher in group I. However, no significant differences were found between preoperative and postoperative physical comfort, physical independence, patient support, and pain subdimensions (P > .05). No difference was observed between the groups in postoperative STAI-1 scores and in the change in STAI-1 scores from preoperative to postoperative (P > .05). Conclusions Although the recovery quality of patients who received ESP block after anesthesia induction was statistically significant compared with those who received ESP block before anesthesia induction, it was not clinically significant. Our findings showed that differences in the timing of ESP block application did not change the results.
