The association between incentive spirometry performance and pain in postoperative thoracic epidural analgesia.
Effective use of postoperative incentive spirometry improves patient outcomes but is limited by pain after thoracic and upper abdominal surgery. Thoracic epidurals are frequently used to provide analgesia and attenuate postoperative pulmonary dysfunction. We hypothesized that, in patients with thoracic epidurals for thoracic and abdominal surgery, high pain scores would be associated with poorer incentive spirometry performance, even when accounting for other variables. ⋯ The present study suggests that pain with deep breathing is more indicative of thoracic epidural efficacy than is pain at rest. Furthermore, incentive spirometry performance could be used as another indicator of thoracic epidural efficacy. This may be particularly useful in patients reporting high pain scores postoperatively.

Epinephrine Administration in Lipid-Based Resuscitation in a Rat Model of Bupivacaine-Induced Cardiac Arrest: Optimal Timing.
The medical community commonly uses lipid emulsion combined with epinephrine in local anesthetic-induced cardiac arrest, but the optimal timing of epinephrine administration relative to lipid emulsion is currently unknown and needs to be determined. ⋯ In the rat model of bupivacaine-induced cardiac arrest, the optimal timing for the administration of epinephrine to produce best outcomes of successful cardiopulmonary resuscitation is immediately after the completion of the lipid emulsion bolus. This optimal timing/therapeutic window is of paramount importance.
