Randomized Controlled Trial Comparative Study
Transdermal diclofenac patch vs eutectic mixture of local anesthetics for venous cannulation pain.
To compare the efficacy and side effects of transdermal diclofenac patch with eutectic mixture of local anesthetic (EMLA) cream in attenuating venous cannulation pain. ⋯ Transdermal diclofenac patch and EMLA are equally effective in reducing venous cannulation pain, but signs of erythema, induration and edema are less frequently observed with the transdermal diclofenac patch.

Randomized Controlled Trial Comparative Study
Ultrasound guidance improves success rate of axillary brachial plexus block.
The purpose of this study is to determine if real time ultrasound guidance improves the success rate of axillary brachial plexus blockade. ⋯ This study demonstrates that ultrasound guidance, with or without concomitant nerve stimulation, significantly improves the success rate of axillary brachial plexus block.

Randomized Controlled Trial
The effect of colloid and crystalloid preloading on thromboelastography prior to Cesarean delivery.
Fluid preloading with colloids reduces hypotension after spinal anesthesia for Cesarean delivery more effectively than crystalloids. However, the effects of fluid preloading regimens on coagulation in pregnant patients remain unresolved. The aim of this study was to compare the effects on coagulation of fluid preloading with 6% hydroxyethyl starch (HES) and lactated Ringer's (LR) solution using thromboelastography (TEG) with kaolin-activated whole blood in healthy pregnant patients prior to spinal anesthesia for Cesarean delivery. ⋯ Fluid preloading with 500 mL 6% HES in healthy parturients produced mild coagulation effects, as measured with TEG, prior to spinal anesthesia for Cesarean delivery. No significant effects on coagulation with TEG were observed following preloading with 1500 mL LR.
