Randomized Controlled Trial Comparative Study Clinical TrialEpidural infusions for labor analgesia: a comparison of 0.2% ropivacaine, 0.1% ropivacaine, and 0.1% ropivacaine with fentanyl.
Epidural infusion of 0.2% ropivacaine is recommended by the manufacturer for labor analgesia, but lower concentrations may be effective. The objective of this study was to compare 0.1% ropivacaine with 0.2% ropivacaine and to examine the effect of addition of fentanyl. ⋯ We conclude that epidural infusion of 0.1% ropivacaine alone at 10 mL/h provided adequate analgesia in the first stage of labor, and that the addition of 2 microg/mL fentanyl to that concentration improved analgesia to a quality similar to 0.2% ropivacaine alone.

Randomized Controlled Trial Comparative Study Clinical TrialSuprascapular nerve block for ipsilateral shoulder pain after thoracotomy with thoracic epidural analgesia: a double-blind comparison of 0.5% bupivacaine and 0.9% saline.
Despite receiving thoracic epidural analgesia, severe ipsilateral shoulder pain is common in patients after thoracotomy. We recruited 44 patients into a double-blinded randomized placebo-controlled study to investigate whether suprascapular nerve block would treat postthoracotomy shoulder pain effectively. All patients received a standard anesthetic with a midthoracic epidural. Thirty patients who experienced shoulder pain within 2 h of surgery were randomly assigned to receive a suprascapular nerve block with either 10 mL of 0.5% bupivacaine or 10 mL of 0.9% saline. Shoulder pain was assessed before nerve blockade, at 30 min, and then hourly for 6 h after the block using a visual analog scale (VAS) and a 5-point verbal ranking score (VRS). The incidence of shoulder pain before nerve block was 78%. There was no significant decrease in either VAS or VRS in the Bupivacaine group. These results suggest that this pain is unlikely to originate in the shoulder and lead us to question the role of a somatic afferent in referred visceral pain. We conclude that suprascapular nerve block does not treat ipsilateral shoulder pain after thoracotomy in patients with an effective thoracic epidural. ⋯ This randomized, double-blinded, placebo-controlled trial showed that suprascapular nerve block does not treat the severe ipsilateral shoulder pain that patients experience after thoracotomy. This has implications for established theories of referred pain and indicates that this pain is unlikely to originate in the shoulder.

ReviewThe role of epidural analgesia and anesthesia in surgical outcomes.
Recent clinical evidence suggests that EAA used in combination with general anesthesia has a beneficial effect on surgical outcome compared with general anesthesia and systemic analgesia. Those complications with clear evidence of a reduced incidence in prospective, randomized studies are shown in Table 2. The benefits are greatest in high-risk patients who receive thoracic epidural blockade with local anesthetic agents. Besides reducing the incidence of certain major complications, the adjunctive use of EAA reduces ICU care, hastens recovery, and has cost savings.

Randomized Controlled Trial Comparative Study Clinical TrialSkin disinfection before epidural catheterization: comparative study of povidone-iodine versus chlorhexidine ethanol.
Chlorhexidine is better than povidone-iodine for skin preparation before intravascular device insertion or blood culture collection, but it is not known whether chlorhexidine is superior in reducing the colonization of continuous epidural catheters. ⋯ The effect of 0.5% chlorhexidine ethanol is not different from that of 10% povidone-iodine in reducing catheter colonization associated with short-term epidural catheter placement.

Randomized Controlled Trial Comparative Study Clinical Trial
Lidocaine with fentanyl, compared to morphine, marginally improves postoperative epidural analgesia in children.
To compare the epidural administration of fentanyl (1 microg/mL) combined with lidocaine 0.4% to preservative-free morphine for postoperative analgesia and side effects in children undergoing major orthopedic surgery. ⋯ Postoperative epidural fentanyl with lidocaine infusion provides slightly better analgesia than conventional bolus administration of epidural morphine. Side-effects or risk of systemic toxicity were not augmented by the addition of lidocaine to epidural opioids.
