Fig. 2From: Selective spinal anesthesia with hyperbaric prilocaine provides better perioperative pain control than local anesthesia for ambulatory inguinal hernia repair without affecting discharging time: a randomized controlled trialPerioperative Pain. The box plot shows pain scores during and after surgery performed by unilateral spinal anesthesia with hyperbaric prilocaine (Group A) vs. local anesthesia performed by surgeon (Group B). Data include maximum pain reported in a 0-10 Numeric Rating Sale, measured both intra and postoperatively. Postoperative values were recorded in PACU at 60 minutes after the end of surgery. Values are expressed as mean (horizontal bars) with 25th–75th (box) and 10th–90th (whiskers); *denotes statistical significance (p < 0.05); NRS: Numeric Rating ScaleBack to article page
