Randomized Controlled Trial Comparative Study Clinical TrialContinuous infusion is superior to bolus doses with thoracic paravertebral blocks after thoracotomies.
This study was designed to determine whether a continuous thoracic paravertebral infusion of bupivacaine (continuous TPVI) offers a higher quality of analgesia than a bolus regimen after thoracotomy. ⋯ Results suggest that continuous TPVI provides better pain control than the bolus regimen after this kind of surgery.

Randomized Controlled Trial Clinical TrialEffects of positive end-expiratory pressure ventilation on splanchnic oxygenation in humans.
To examine the influence of positive end-expiratory pressure (PEEP) ventilation on splanchnic oxygenation and lactate production in humans without pulmonary disorders. ⋯ Ventilation with PEEP causes reductions in CO and MAP, resulting in a comparable impairment of systemic and splanchnic oxygen. The absence of changes in lactate concentrations indicates that a critical reduction in systemic and splanchnic oxygenation is unlikely during ventilation with low or high PEEP levels.
