Randomized Controlled Trial[Chronic postoperative pain after general anesthesia with or without a single-dose preincisional paravertebral nerve block in radical breast cancer surgery].
Over 50% of patients still experience pain a year after mastectomy with or without lymphadenectomy. We aimed to determine the association between anesthetic technique, acute postoperative pain intensity, and the development of chronic postoperative pain. ⋯ Four to 5 months after mastectomy, fewer cases of chronic pain developed in the group operated under general anesthesia with a preincisional paravertebral block than in the group that received only general anesthesia, with postoperative morphine chloride for analgesia.

Comparative Study[Agreement between verbal numerical scale and visual analog scale assessments in monitoring acute postoperative pain].
To determine the agreement between verbal numerical and visual analog scale assessments of acute postoperative pain on 3 consecutive days. ⋯ Agreement between pain assessments on the visual analog and verbal numerical scales can be considered good or very good on all 3 days, with stronger agreement when the scales are used in patients over the age of 65 years. Cooperation was better for the numerical scale than for the visual analog scale. Scores on the verbal numerical scale were consistently higher than scores on the visual analog scale.
