Randomized Controlled TrialThe relative potencies for motor block after intrathecal ropivacaine, levobupivacaine, and bupivacaine.
In this study, we sought to determine the median effective dose (ED50) for motor block of intrathecal ropivacaine, levobupivacaine, and bupivacaine and to define their motor-blocking potency ratios. ⋯ There is a clinical profile of potency for motor block for the pipecolylxylidines when administered spinally: low, intermediate, and high for ropivacaine, levobupivacaine, and bupivacaine, respectively.

Randomized Controlled Trial Comparative Study
Comparison of peri- and intraarticular analgesia with femoral nerve block after total knee arthroplasty: a randomized clinical trial.
Postoperative pain after total knee arthroplasty (TKA) can be difficult to manage and may delay recovery. Recent studies have suggested that periarticular infiltration with local anesthetics may improve outcome. ⋯ Peri- and intraarticular application of analgesics by infiltration and bolus injections can improve early analgesia and mobilization for patients undergoing TKA. Further studies of optimal drugs, dosage, and duration of this treatment are warranted.

Randomized Controlled TrialFluid challenge in patients submitted to spinal block.
The practice of routinely prehydrating patients by infusing a colloid solution for prevention of spinal anesthesia-induced hypotension has been challenged recently. The aim of the study was to evaluate the influence of a 15 mL/kg pre-emptive bolus of colloids (6% hydroxyhethyl starch) on heart rate (HR), mean arterial blood pressure (MAP), cardiac index (CI) in patients submitted to subarachnoid block with hyperbaric bupivacaine 0.5%, 0.2 mg/kg for orthopedic surgery of the lower limb. ⋯ Our data show that despite to fluid challenge, we could not prevent MAP decrease in Group A, even if it is more marked in Group B.

For endoprosthetic knee surgery, intensive postoperative pain therapy is necessary. We therefore evaluated whether the combination of continuous psoas compartment and sciatic analgesia (PSC) is as effective as epidural analgesia (EPI) and whether it provides better analgesia than patient-controlled intravenous analgesia with piritramide (PCA). ⋯ Analgesia with PSC catheters or EPI catheter is superior to PCA regarding pain levels, analgesic requirements, and patient satisfaction. There was no difference in functional outcome between the 3 groups.

Comparative StudyPrevalence of facet joint pain in chronic low back pain in postsurgical patients by controlled comparative local anesthetic blocks.
To evaluate the prevalence of facet joint pain in patients with chronic low back pain (CLBP) after surgical intervention(s). ⋯ Facet joints are clinically important pain generators in a small but significant proportion of patients with recurrent CLBP after various surgical intervention(s).
