Objective: We produced a special needle for stellate ganglion block (SGB needle) to lessen tissue damage caused by puncture. The tip of the SGB needle is in the shape of a pyramid with sharp edges, and there is a hole for injection 1.5mm from the tip. The aim of this study was to investigate the special properties and clinical usefulness of the SGB needle. Methods: We experimentally compared damage at the puncture site and pressure needed for puncture of the SGB needle to those of a standard disposable needle. In addition, we examined the effect of SGB, complications, impressions of surgeons and complaints of patients, using this needle for 89 blocks in 19 patients. Results: The tissue damage caused by the SGB needle was smaller than, and the pressure needed for puncture was equivalent to that of a standard disposable needle. Clinical use of the SGB needle caused no problems with puncture or injection, and the nerve block was completely effective. There were neither major complications nor any subcutaneous bleeding or induration. Patients had no complaints about the SGB needle. Conclusion: This study indicates that the SGB needle is useful in clinical work.
