Hemodynamic effects of thoracic epidural analgesia in ovine hyperdynamic endotoxemia.
Thoracic epidural analgesia (TEA) is increasingly used for perioperative analgesia. If patients with TEA develop sepsis or systemic inflammatory response subsequent to extended surgery the question arises if it would be safe to continue TEA with its beneficial effects of improving gastrointestinal perfusion and augmenting tissue oxygenation. A major concern in this regard is hemodynamic instability that might ensue from TEA-induced vasodilation. The objective of the present study was to assess the effects of TEA on systemic and pulmonary hemodynamics in a sepsis model of hyperdynamic endotoxemia. ⋯ From a hemodynamic point of view, TEA presents as a safe treatment option in sepsis or systemic inflammatory response syndrome.

Anatomical location of the bifurcation of the sciatic nerve in the posterior thigh in infants and children: a formula derived from MRI imaging for nerve localization.
Sciatic nerve block is performed at the popliteal fossa for various surgical procedures in infants and children. The aim of this study is to review magnetic resonance imaging scans in children of various ages to assess the location of the division of the nerve in the posterior thigh. ⋯ We speculate that this knowledge will assist practitioners who use nerve stimulation techniques for sciatic nerve blocks in children of all ages.

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.
