Randomized Controlled Trial Comparative Study Clinical TrialTotal knee replacement: a comparison of ropivacaine and bupivacaine in combined femoral and sciatic block.
Femoral and sciatic nerve block may improve post-operative analgesia following total knee replacement. ⋯ Femoral and sciatic blockade following intrathecal bupivacaine/diamorphine provided superior analgesia when compared with intrathecal bupivacaine/diamorphine alone. There were no significant clinical differences between the group receiving bupivacaine 7.5 mg x ml(-1) and the group receiving ropivacaine 7.5 mg x ml(-1).

Randomized Controlled Trial Clinical Trial[Control of postoperative pain in heart surgery. Comparison of analgesics].
Evaluation of the efficacy of three analgesic drugs (tramadol, ketorolac, and morphine) for the control of postoperative pain in cardiac surgery. ⋯ Tramadol in continuous infusion (dose 12 mg/h) proved to be effective for the control of postoperative pain after cardiac surgery. The proposed dose represents a good compromise between analgesic efficacy and interference with the vital functions of operated patients.

Randomized Controlled Trial Clinical TrialA dose-response study of adrenaline combined with lignocaine 2%: effect on acute postoperative pain after oral soft tissue surgery.
The combination of lignocaine and adrenaline may cause more postoperative pain than other types of local anaesthetic agents with comparable clinical efficacy. This study investigates the dose-response effect of adrenaline added to lignocaine on postoperative pain, when used as local anaesthetic for oral soft tissue surgery. ⋯ High adrenaline concentrations (1 : 80 000) combined with lignocaine local anaesthetic solution offers no advantage with respect to pain alleviation during the immediate postoperative pain period. High exogenous adrenaline concentrations may play a significant role in enhancing acute postoperative intensity.

Randomized Controlled Trial Clinical TrialThe preemptive analgesic effect of intraarticular bupivacaine and morphine after ambulatory arthroscopic knee surgery.
Intraarticular (IA) morphine provides effective postoperative analgesia after arthroscopic knee surgery. Some investigators have suggested that the preemptive administration of opioids may reduce postoperative analgesic requirements and hypersensitivity. We evaluated the analgesic effect of administering IA morphine either before or after surgical incision in patients undergoing arthroscopic knee surgery under local anesthesia. Forty patients undergoing arthroscopic meniscectomy were randomized into two groups. All patients received IA bupivacaine 0.25% before and after surgery together with IV sedation using midazolam and propofol. The Preemptive IA Morphine group received a single 3-mg dose of morphine with their preoperative bupivacaine. The Post-IA Morphine group received 3 mg of morphine at the completion of surgery with the postoperative bupivacaine. After surgery, pain scores, the time to first opioid use, and 24-h analgesic use were recorded. Analgesic duration, defined as the time from completion of surgery until first opioid use, was significantly longer in those patients receiving preoperative (953 +/- 209 min) versus postoperative (556 +/- 121 min) IA morphine. The 24-h acetaminophen and oxycodone use was less in the Preemptive group (2.2 +/- 1.2 pills) versus the Postoperative group (3.0 +/- 1.2 pills). We conclude that IA morphine provides a longer duration of postoperative analgesia with less 24-h opioid use when administered before surgery. ⋯ The administration of intraarticular morphine 3 mg before arthroscopic knee surgery provides a longer duration of analgesia with less 24-h opioid use compared with the administration of the drug at the completion of surgery.

Clinical Trial Controlled Clinical TrialMusic and the PACU environment.
Pain is a common problem in the PACU, resulting in negative respiratory, cardiovascular, gastrointestinal, renal, neuroendocrine, and autonomic nervous system consequences for patients. Pain relief contributes to improved patient outcomes and is also an important component of patient satisfaction, particularly in light of today's environment of high competition among hospitals for patients. Music and quiet conversation by staff, contributing to low noise levels in the PACU environment, have the potential to provide pain relief and improve patient satisfaction with the PACU experience. ⋯ A total of 99% of the participants remembered their PACU stay. When asked to remember aspects of comfort during the PACU stay, the experimental group reported (1) significantly less noise caused by staff voices and equipment, (2) greater perception of availability of nurses, and (3) significantly more positive perception of their PACU stay. The study findings support the potential for music played throughout the PACU stay to positively affect the pain experience and improve comfort among patients having surgery.
