Complications in Pediatric Regional Anesthesia: An Analysis of More than 100,000 Blocks from the Pediatric Regional Anesthesia Network.

WHAT WE ALREADY KNOW ABOUT THIS TOPIC: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Complications in pediatric regional anesthesia are rare, so a large sample size is necessary to quantify risk. The Pediatric Regional Anesthesia Network contains data on more than 100,000 blocks administered at more than 20 children's hospitals. This study analyzed the risk of major complications associated with regional anesthesia in children. METHODS: This is a prospective, observational study of routine clinical practice. Data were collected on every regional block placed by an anesthesiologist at participating institutions and were uploaded to a secure database. The data were audited at multiple points for accuracy. RESULTS: There were no permanent neurologic deficits reported (95% CI, 0 to 0.4:10,000). The risk of transient neurologic deficit was 2.4:10,000 (95% CI, 1.6 to 3.6:10,000) and was not different between peripheral and neuraxial blocks. The risk of severe local anesthetic systemic toxicity was 0.76:10,000 (95% CI, 0.3 to 1.6:10,000); the majority of cases occurred in infants. There was one epidural abscess reported (0.76:10,000, 95% CI, 0 to 4.8:10,000). The incidence of cutaneous infections was 0.5% (53:10,000, 95% CI, 43 to 64:10,000). There were no hematomas associated with neuraxial catheters (95% CI, 0 to 3.5:10,000), but one epidural hematoma occurred with a paravertebral catheter. No additional risk was observed with placing blocks under general anesthesia. The most common adverse events were benign catheter-related failures (4%). CONCLUSIONS: The data from this study demonstrate a level of safety in pediatric regional anesthesia that is comparable to adult practice and confirms the safety of placing blocks under general anesthesia in children.

Benefit of the minimal invasive ultrasound-guided single shot femoro-popliteal block for ankle surgery in comparison with spinal anesthesia.

BACKGROUND: Ultrasound-guided regional anesthesia has gained popularity for ankle and foot surgery. The aim of our study was to investigate the sufficiency of anesthesia for ankle surgery as well as duration of analgesia in postoperative period, using minimal invasive ultrasound-guided regional anesthesia, and to compare it with anesthesia and postoperative analgesia following spinal anesthesia. METHODS: This prospective study included 40 adult trauma patients with bimalleolar fracture who were scheduled for surgery. They were randomly assigned and divided in two groups. Patients from the first group underwent an Ultrasound-guided femoro-popliteal block (US-FPB), while a spinal anesthesia (SA) was performed for the second group. The local anesthetic 0.5% bupivacaine was used in both groups. RESULTS: Eighteen patients from the first and nineteen patients from the second group completed the study. Levels of anesthesia were sufficient in both groups without significant differences. Duration of postoperative analgesia was significantly higher in US-FPB group in comparison to SA group (12 ± 3 vs. 3 ± 1 h) (p < 0.001). At the same time, onset of complete sensory motor block was significantly faster in SA group in comparison to US-FPB group (5 ± 1 vs. 8 ± 3 min) (p < 0.001). CONCLUSION: Minimal invasive US-FPB provides sufficient anesthesia for ankle fracture. In comparison to the SA group, patients from the US-FPB group achieved significantly longer postoperative analgesia, while faster onset of anesthesia was noted in SA group.
