Randomized Controlled Trial Clinical TrialIntrathecal sufentanil for extracorporeal shock wave lithotripsy provides earlier discharge of the outpatient than intrathecal lidocaine.
Many anesthetic techniques are currently used for extracorporeal shock wave lithotripsy (ESWL). This randomized, prospective, double-blind study was designed to examine postoperative recovery with two anesthetic techniques for unilateral ESWL; i.e., intrathecal sufentanil versus intrathecal 5% lidocaine. The incidence of adverse effects was also assessed. ⋯ There were no differences in PONV between the two groups. Intrathecal sufentanil provided an enhanced recovery profile with significantly earlier home discharge when compared with intrathecal lidocaine. In conclusion, intrathecal sufentanil is a safe and effective method of anesthesia for outpatient unilateral ESWL.

Randomized Controlled Trial Clinical TrialIntraarticular morphine analgesia in chronic pain patients with osteoarthritis.
Controlled clinical studies have shown that local administration of morphine can significantly relieve acute postoperative pain. This analgesic effect is long-lasting (up to 48 h) and is mediated by peripheral opioid receptors. Experimental evidence shows that analgesic effects of peripheral opioids and the density of opioid receptors on peripheral sensory nerves increase with the duration of painful inflammatory processes. ⋯ The analgesic effect was surprisingly long-lasting and extended into Phase II, a carry-over effect that prevented the analysis of Phase II. No side effects were reported. The treatment of arthritic pain by peripherally acting opioids may be a promising alternative to currently available medications that have serious side effects.

Randomized Controlled Trial Clinical TrialSuprascapular nerve block for postoperative pain relief in arthroscopic shoulder surgery: a new modality?
Arthroscopic shoulder surgery has a 45% incidence of severe postoperative pain. Opiates and interscalene nerve blocks have a high incidence of side effects, and intraarticular local anesthetic has been shown to be ineffective when used for postoperative pain relief. The suprascapular nerve supplies 70% of the sensory nerve supply to the shoulder joint, and local anesthetic block of this nerve is effective in certain shoulder pain disorders. ⋯ A 24-h phone call interview revealed a 40% reduction in analgesic consumption and a reduction in verbal pain scores at rest and on abduction. There were no complications from the suprascapular nerve block. This study demonstrates that a suprascapular nerve block for pain relief in arthroscopic shoulder surgery is an effective and safe modality of postoperative pain relief.
