Summary
Tissue coring during pediatric caudal blocks is uncommon with both hollow and specialized caudal needles. This study found no significant difference in cell transport between the two needle types, suggesting low risk for this procedure.
Area of Science:
- Pediatric Anesthesiology
- Pain Management
- Surgical Techniques
Background:
- Caudal injections are common in pediatric pain management.
- Concerns exist regarding potential tissue coring with needles during these procedures.
- Evaluating needle types for safety and efficacy is crucial.
Purpose of the Study:
- To investigate tissue coring during caudal injections in children using 22-gauge (G) hollow needles versus 22-G caudal block needles.
- To analyze the cellular composition of any potential coring material.
Main Methods:
- Seventy children undergoing caudal block anesthesia were randomized into two groups.
- Group I received a 22-G hollow needle; Group II received a 22-G caudal block needle.
- Needles were flushed, and material analyzed by a pathologist for cell types and mitotic activity.
Main Results:
- Nucleated cells without mitotic activity were found in 8.5% of both groups.
- Bloody material was present in 8.5% (Group I) and 2.8% (Group II).
- Non-nucleated epidermal cells were detected in over 94% of patients in both groups; no cells with mitotic activity were observed.
Conclusions:
- The incidence of transporting nucleated epidermal cells without mitotic activity during caudal puncture is low.
- There is no significant difference in cell transport between 22-G hollow and 22-G caudal block needles.
- While rare, the potential for transporting nucleated cells with mitotic activity from the stratum basale cannot be entirely ruled out.
