A somewhat reassuring study on pediatric anesthesia regional anesthesia that included both peripheral nerve and neuraxial blocks finds: “In a prospective multicenter cohort of more than 100,000 blocks in children, there were no cases of permanent neurologic deficit associated with regional anesthesia. The rate of transient neurologic deficit was low at 2.4 per 10,000, and the incidence of local anesthesia toxicity was also low at 0.76 per 10,000”.
There was only one epidural abscess, and one epidural hematoma in a paravertebral block. Transient neurological deficits did not differ between peripheral and neuraxial blocks. Importantly, no additional risk was observed with placing blocks under general anesthesia.
The most common adverse events were benign catheter-related failures (4%).
