Randomized Controlled Trial Comparative StudyEffect of Topical Morphine on Acute and Chronic Postmastectomy Pain: What Is the Optimum Dose?
Poorly controlled postoperative pain is strongly associated with the development of chronic pain. We aimed to investigate the effect of topical morphine (in 1 of 3 doses: 5, 10, or 15 mg) on acute and chronic neuropathic pain after modified radical mastectomy for cancer breast. ⋯ Topical morphine controlled acute postmastectomy pain in a dose-dependent manner and reduced the incidence and severity of chronic postmastectomy pain syndrome.

Randomized Controlled Trial Comparative StudyDetermining the Learning Curve for Acquiring Core Sonographic Skills for Ultrasound-Guided Axillary Brachial Plexus Block.
The objectives of this study were to determine the learning curve for capturing sonograms and identifying anatomical structures relevant to ultrasound-guided axillary brachial plexus block and to determine if massed was superior to distributed practice for this core sonographic skill. ⋯ The proficiency of participants in capturing sonograms and identifying anatomical structures improved significantly over 8 to 10 learning sessions. Because of sample size issues, we cannot make a firm conclusion regarding massed versus distributed practice for this core sonographic skill.

Randomized Controlled Trial Comparative StudyAnalgesic Effects of Ultrasound-Guided Serratus-Intercostal Plane Block and Ultrasound-Guided Intermediate Cervical Plexus Block After Single-Incision Transaxillary Robotic Thyroidectomy: A Prospective, Randomized, Controlled Trial.
Single-incision transaxillary robotic thyroidectomy (START) requires substantial tissue disruption, which produces moderate-to-severe pain in the axilla and neck areas during the early postoperative period. This study aimed to investigate the analgesic effects of ultrasound-guided serratus-intercostal plane blocks and intermediate cervical plexus blocks (CPBs) on the early postoperative pain after START. ⋯ After START, a serratus-intercostal plane block performed at the level of the third rib was an effective analgesic technique for axillary pain; however, the clinical effectiveness of intermediate CPB for neck pain may be limited.

Randomized Controlled Trial Comparative StudyPudendal Versus Caudal Block in Children Undergoing Hypospadias Surgery: A Randomized Controlled Trial.
Postoperative pain management after hypospadias surgery is often challenging. Caudal block is used for analgesia but has limitations. This study compares the analgesic efficiency of pudendal block with that of caudal block in pediatric patients undergoing hypospadias repair surgery. ⋯ For the pudendal group, the pain scores for the first 24 hours after the surgery were significantly lower and the duration of analgesia was longer.

Randomized Controlled Trial Comparative StudyA Comparison of Combined Suprascapular and Axillary Nerve Blocks to Interscalene Nerve Block for Analgesia in Arthroscopic Shoulder Surgery: An Equivalence Study.
The primary objective of this study was to compare the analgesic efficacy of combined suprascapular and axillary nerve block (SSAX) with interscalene block (ISB) after arthroscopic shoulder surgery. Our hypothesis was that ultrasound-guided SSAX would provide postoperative analgesia equivalent to ISB. ⋯ Combined suprascapular and axillary nerve block provides nonequivalent analgesia compared with ISB after arthroscopic shoulder surgery. While SSAX provides better quality pain relief at rest and fewer adverse effects at 24 hours, ISB provides better analgesia in the immediate postoperative period. For arthroscopic shoulder surgery, SSAX can be a clinically acceptable analgesic option with different analgesic profile compared with ISB.
