Randomized Controlled Trial
The effect of preoperative pentoxifylline on postoperative pain and development of secondary hyperalgesia in patients undergoing laparoscopic appendectomy; a randomized, double-blind, placebo-controlled trial study.
After surgery and loss of anesthetic effect, postoperative pain can annoy the patient and affect patient satisfaction with treatment. This study was aimed at evaluating the effect of preoperative pentoxifylline (PTX) on postoperative pain and development of secondary hyperalgesia in patients undergoing laparoscopic appendectomy (LA). ⋯ Findings suggest that oral administration of PTX 1 hour before surgery in patients undergoing LA can reduce postoperative pain in patients and prevent secondary hyperalgesia at a surgical site.

Randomized Controlled Trial
Radiofrequency thoracic sympathectomy for sympathetically maintained chronic post-mastectomy pain, a preliminary report: six months results.
Evaluation of the analgesic efficacy of radiofrequency thoracic sympathectomy for sympathetically maintained post-mastectomy pain syndrome (PMPS). ⋯ Radiofrequency thoracic sympathectomy for sympathetically maintained PMPS decreased VAS pain scores and reduced the need for anti-neuropathic drugs, particularly opioid medications, and provided better patient satisfaction.
