Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialComparative evaluation of four different infusion rates of ropivacaine (2 mg/mL) for epidural labor analgesia.
Previous studies have reported comparable efficacy for ropivacaine and bupivacaine when used for labor analgesia at concentrations of 2.5 mg/mL. In this multicenter study, we assessed ropivacaine at the commercially available concentration of 2 mg/mL (0.2%) for labor pain management. ⋯ The 2 mg/mL of ropivacaine produces satisfactory labor analgesia at epidural infusion rates of 4, 6, 8, and 10 mL/hour, provided supplemental bolus dosages are available. Clinically, a rate of 6 mL/hour may be the lowest effective rate that provides the best combination of pain relief, motor block, and rebolusing, although rates of 8 and 10 mL/hour produced similar results.

Randomized Controlled Trial Comparative Study Clinical TrialUltrasonographic guidance reduces the amount of local anesthetic for 3-in-1 blocks.
Recently it has been demonstrated that the use of ultrasound (US) improves the onset time and the quality of sensory block for 3-in-1 blocks compared with conventional nerve stimulator (NS) techniques. The present study was designed to evaluate if US guidance for 3-in-1 blocks reduces the amount of local anesthetic compared to NS guidance. ⋯ The amount of local anesthetic for 3-in-1 blocks can be reduced by using US guidance compared with the conventional NS-guided technique.

Randomized Controlled Trial Clinical TrialPre-incision infiltration with lidocaine reduces pain and opioid consumption after reduction mammoplasty.
To determine the analgesic efficacy of preoperative tumescent infiltration with lidocaine for reduction mammoplasty. ⋯ Preoperative tumescent infiltration with lidocaine results in reduced pain and lower postoperative opioid requirements in the initial hours after reduction mammoplasty.

Randomized Controlled Trial Clinical TrialLocal anesthetic effect of tramadol, metoclopramide, and lidocaine following intradermal injection.
We observed clinically that tramadol and metoclopramide appear to have local anesthetic action. Tramadol is a central-acting analgesic. Metoclopramide is a commonly used antiemetic. The local anesthetic effect of tramadol in reducing propofol injection pain has never been mentioned, although it was speculated with metoclopramide. ⋯ Intradermal tramadol or metoclopramide can produce local anesthetic effect.
