Case ReportsUneventful removal of an epidural catheter guided by impedance aggregometry in a patient with recent coronary stenting and treated with clopidogrel and acetylsalicylic acid.
This report suggests that impedance aggregometry can be helpful to assess optimum time for and minimize the risk of catheter removal during double antiplatelet therapy. ⋯ Balancing the risks of stent occlusion and epidural bleeding, bedside impedance aggregometry helped to identify the optimum time window for epidural catheter removal with the lowest bleeding risk in this patient.

Randomized Controlled Trial Comparative StudyDyloject, a novel injectable diclofenac formulation, offers greater safety and efficacy than voltarol for postoperative dental pain.
Voltarol for injection (a diclofenac sodium formulation employing polyethylene glycol and benzyl alcohol [PG-BA] as excipients) is marketed in Europe but not in North America. A suspension, PG-BA diclofenac sodium, requires preparation for each patient and slow IV infusion to minimize venous irritation. Dyloject, a novel diclofenac formulation, employs hydroxypropyl beta-cyclodextrin (HPbetaCD) to solubilize diclofenac in a small volume. We compared the efficacy and safety of an IV HPbetaCD diclofenac sodium bolus, a 30-minute PG-BA diclofenac sodium infusion, and placebo in post-molar extraction pain. ⋯ IV bolus HPbetaCD diclofenac sodium produced analgesia more quickly than, and with equal duration as, the 30-minute PG-BA diclofenac sodium infusion. Pooled data on thrombophlebitis from the present investigation and our prior studies of the novel formulation indicate this adverse effect is less frequent and less severe with HPbetaCD diclofenac sodium than with PG-BA diclofenac sodium.

Randomized Controlled TrialMotor blocking minimum local anesthetic concentrations of bupivacaine, levobupivacaine, and ropivacaine in labor.
Adequate comparison of blocking capabilities of local anesthetics should be done with some knowledge of their relative potencies. The objective of this clinical trial was to simultaneously determine the motor blocking minimum local anesthetic concentrations (MMLAC) and the relative potency ratios for racemic bupivacaine, levobupivacaine, and ropivacaine during labor. ⋯ This study confirms a motor blocking hierarchy for the three pipecoloxylidines.
