Inguinal hernia repair is one of the most common operations performed worldwide. Intractable pain following this operation is a potential debilitating complication. The exact etiology of this complex pain is unknown and the treatment of chronic pain after inguinal herniorrhaphy can be a difficult task for both the patient and the clinician. ⋯ This study is a retrospective assessment of a new technique that was applied to a limited number of cases. It remains to be determined whether this technique is superior to the classical open surgical technique in the future. Our findings warrant further studies on the utilization of peripheral nerve stimulation with chronic post herniorrhaphy pain.

Review Meta Analysis
Perineural dexamethasone added to local anesthesia for brachial plexus block improves pain but delays block onset and motor blockade recovery.
Multiple studies have shown that perineural dexamethasone improves postoperative analgesia. However, some studies have shown minimal benefit, and have raised concerns regarding adverse physio-chemical effects of perineural dexamethasone. Furthermore, there is a paucity of studies wherein control (IV) dexamethasone was considered. ⋯ Perineural dexamethasone addition to local anesthetic solutions significantly improved postoperative pain in brachial plexus block without increasing complications. However, perineural adjuvant dexamethasone delayed the onset of sensory and motor block, and prolonged the duration of motor block. Smaller doses of dexamethasone (4 - 5 mg) were as effective as higher doses (8 - 10 mg).
