Effects of Sodium Bisulfite With or Without Procaine Derivatives on Axons of Cultured Mouse Dorsal Root Ganglion Neurons

Conclusions: NaHSO3 resulted in a dose-dependent damage to the cell membrane and axonal transport, especially when used in combination with procaine or chloroprocaine.

In this study, we randomly assigned 42 patients with severe ZAP beyond the acute phase, as determined by a numeric rating scale (NRS) score ≥7, to receive continuous epidural infusion of local anesthetics with either a one-time 5-mg dose or intermittent repeated doses (15 mg total) of dexamethasone. We found that intermittent repeated epidural dexamethasone bolus resulted in reduced NRS scores and an increased likelihood of complete remission in ZAP patients without any adverse effects. Thus, our results suggest that intermittent repeated epidural dexamethasone administration is safe and effective for treatment of ZAP b...

Background Dorsal root ganglion field stimulation is an analgesic neuromodulation approach in use clinically, but its mechanism is unknown as there is no validated animal model for this purpose. The authors hypothesized that ganglion stimulation is effective in reducing pain-like behaviors in preclinical chronic pain models.Methods The authors provided ganglion stimulation or spinal cord stimulation to rats with traumatic neuropathy (tibial nerve injury), or osteoarthritis induced by intraarticular knee monosodium iodoacetate, or without injury (na ïve). Analgesia was evaluated by testing a battery of pain-related ref...

We report four cases of effective analgesia for intractable secondary headache resistant to medical management with high thoracic ESP blocks. In each case, the ESP block provided instant pain relief. We suggest that the findings of this case series indicate that the ESP block may be a useful intervention in patients with severe secondary headache or posterior cervical pain where conventional therapies have limited success, though more studies are necessary.

Conclusions: Concomitant use of bilateral SPG block with general anesthesia is an effective and safe alternative technique to scalp blockade for obtundation of hemodynamic responses due to noxious stimulus during craniotomy surgeries.

Abstract Here, we report a case in which acupuncture combined with trigger point injection was effective in a patient with chronic myofascial pain with referred pain in the masticatory muscles. The patient was a 46-year-old woman with the chief complaint of chronic persistent pain in the region of the left mandibular first molar, which had been extracted 5 months earlier. Stellate ganglion block was performed and amitriptyline administered at another hospital, but were ineffective. At her initial visit to our hospital, her primary complaint was chronic persistent pain in the region of the bilateral mandibular firs...

Authors: Rahimzadeh P, Mahmoudi K, Khodaverdi M, Faiz SHR Abstract Introduction: Laparoscopic gynecologic surgery is one of the most well-known procedures. Pneumoperitoneum with carbon dioxide insufflation can cause unfavorable hemodynamic effects due to catecholamine and vasopressin release. Aim: To examine the effects of stellate ganglion block on hemodynamic response and postoperative pain. Material and methods: In a prospective double blinded randomized parallel study we included 40 patients with ASA physical status I and II, aged between 18 and 50 years with a gynecologic problem candidate for laparosc...

AbstractPurpose of ReviewThe purpose of this manuscript is to provide a comprehensive review of postdural puncture headache (PDPH) with a focus on epidemiology, pathophysiology, treatment, and prophylaxis.Recent FindingsPDPH is an adverse iatrogenic complication of neuraxial anesthesia that occurs following inadvertent puncture of the dura after epidural or spinal anesthesia. The overall incidence of PDPH after neuraxial procedures varies from 6 to 36%. The occurrence of PDPH can lead to increased patient morbidity, delayed discharge, and increased readmission. PDPH is a self-limiting postural headache that most often will...
