CommentCaudal analgesia versus abdominal wall blocks for pediatric genitourinary surgery: systematic review and meta-analysis.
Caudal block is a well-established technique for providing perioperative analgesia in pediatric genitourinary surgery, but abdominal wall blocks such as ilioinguinal-iliohypogastric (II-IH) and transversus abdominis plane (TAP) block are increasingly being used. ⋯ This meta-analysis was limited by unclear risk of selection and performance biases and significant heterogeneity. In summary, II-IH and TAP block are a non-invasive and reasonable alternative to caudal analgesia in pediatric genitourinary surgery.

The anatomical features of an ultrasound-guided Erector Spinae Fascial Plane block in a cadaveric neonatal sample.
Since its inception, the erector spinae plane block has been used for a variety of truncal surgeries with success in both adults and children. However, the anatomical features, route of spread, and dermatomal coverage are still not fully understood in a pediatric population. ⋯ Contrast material was found in the paravertebral, epidural, and intercostal spaces over an average of 5 vertebral levels when using 0.1 mL/kg.

Observational StudyDistribution of injectate administered through a catheter inserted by three different approaches to ultrasound-guided thoracic paravertebral block: a prospective observational study.
Despite the popularity of continuous thoracic paravertebral block (TPVB), there is a paucity of information on catheter tip position and distribution of injectate through the catheter. We observed, in real time, the spread of dye, the catheter tip position and sensory block levels produced with three different (intercostal (IC), transverse process sagittal (TS) and paralaminar (PL)) approaches to ultrasound-guided TPVB in patients undergoing video-assisted thoracoscopic surgery. ⋯ Although a bolus injection through a catheter for ultrasound-guided TPVB produced multiple levels of spread and sensory blockade in more than half the patients, considerable differences existed in the spread regardless of approach.
