Post-thoracotomy pain in children and adolescence: a retrospective cross-sectional study.

Objective: We sought to determine the prevalence of chronic post-thoracotomy pain, defined as persistent or recurring incisional pain for at least 2 months after thoracotomy, in children.

Design: Retrospective cross-sectional study.

Setting: Quaternary pediatric teaching hospital.

Randomized controlled trial comparing pudendal nerve block under ultrasound and fluoroscopic guidance.

Background: Although fluoroscopy is an established imaging modality for pudendal nerve block, ultrasound (US) technique allows physicians better visualization of anatomic structures. This study aimed to compare the effectiveness and safety between the US- and fluoroscopy-guided techniques.

Methods: A randomized, single-blind, split-plot design was used to conduct the study.

Suprascapular nerve block: a narrative review.

Suprascapular nerve blockade (SSNB) is a simple and safe technique for providing relief from various types of shoulder pain, including rheumatologic disorders, cancer, and trauma pain, and postoperative pain due to shoulder arthroscopy. Posterior, superior, and anterior approaches may be used, the most common being the posterior. Recently, an ultrasound-guided approach has been described.

Failed back surgery syndrome.

Background: Failed back surgery syndrome (FBSS) is a chronic pain condition that has considerable impact on the patient and health care system. Despite advances in surgical technology, the rates of failed back surgery have not declined. The factors contributing to the development of this entity may occur in the preoperative, intraoperative, and postoperative periods.

A case of sympathetically mediated headache treated with stellate ganglion blockade.

Background: Chronic pain following trauma may be mediated in part by the sympathetic nervous system. There is evidence of sympathetic nervous system dysfunction in patients who suffer from posttraumatic headaches. Not all patients will obtain relief from conventional and antineuropathic medications.
