BACKGROUND: We evaluated the effect of magnesium sulphate on increased pain in 44 patients undergoing staged bilateral total knee arthroplasty (TKA). METHODS: The magnesium group (n=22) and the control group (n=22) received magnesium sulphate and isotonic saline, respectively, throughout the surgery. Postoperative pain (visual analogue scale, VAS) at rest and the amounts of patient-controlled analgesia (PCA, fentanyl) and rescue analgesia (ketoprofen) administered during the first 48 h were compared between the two groups and within each group between the first and second TKA...

Opioids are increasingly used in alleviating pain, including cancer-related pain and postoperative pain. Unfortunately, the development of tolerance, the resistance of neuropathic pain on opioid analgesia or other undesirable effects may limit their utility. In order to reduce opioid doses, and thereby to avoid the risk of side effects and sudden deaths due to overdosing, attempts have been made to introduce co-analgesics. Due to an increasing amount of data concerning a potential enhance of opioid analgesia by the physiological antagonist of N-methyl-d-aspartate receptors, magnesium ions (Mg(2+)), a concomitant use of such a combination seems to be interesting from a clinical point of view...

PURPOSE: As previously reported, magnesium sulphate administered parenterally significantly increased an opioid antinociception in different kinds of pain. Since the typical form of magnesium salts are poorly and slowly absorbed from the gastrointestinal tract we examined whether their micronized form could increase opioids induced antinociception. METHODS: In behavioural studies on rats morphine, tramadol and oxycodone together with magnesium (lactate dihydrate, hydroaspartate, chloride) in micronized (particles of size D90 < 50 μm) and conventional forms were used...

BACKGROUND: Optimal control of acute postoperative pain and prevention of chronic persistent pain in total knee arthroplasty (TKA) remain a challenge. The main hypothesis was that nerve blocks improve postoperative analgesia especially if perineural adjuvants are added. METHODS: Immediate postoperative pain (24 h) was evaluated every hour in 639 patients using a verbal rating 11-point scale for patient self-reporting of pain (VRS-11). All patients received subarachnoid anesthesia and were randomly allocated in 8 groups: control group, epidural (EA) and single shots femoral (FNB) or adductor canal blocks (ACB), both with and without adjuvants: dexamethasone (+Dexa) or dexmedetomidine (+Dexm)...
