Comparative StudyHigh thoracic epidural block relieves acute herpetic pain involving the trigeminal and cervical regions: comparison with effects of stellate ganglion block.
Stellate ganglion block can promptly relieve acute herpetic pain (AHP) involving the trigeminal and cervical regions. However, repeated blocks are needed to maintain pain relief in most patients with severe AHP. Because continuous epidural block is easily performed using an indwelling catheter, we compared the effect of high thoracic epidural block with that of stellate ganglion block to relieve moderate-to-severe AHP involving these regions. ⋯ High thoracic epidural block was as effective as stellate ganglion block in relieving moderate-to-severe AHP involving the trigeminal and cervical regions.

Epidural pressures and spread of 2% lidocaine in the epidural space: influence of volume and speed of injection of the local anesthetic solution.
The impact of epidural pressures on the spread of epidural block is controversial. This study examined the effect of volume and speed of injection of local anesthetics on epidural pressures and the spread of anesthesia. ⋯ The peak epidural pressures correlated with the speed of injection of the lidocaine solution and not with its volume, whereas the remaining epidural pressures correlated with its volume and not with the speed of injection. The extent and duration of the thermal block exhibited a more consistent correlation (inverse and direct, respectively) with the epidural pressures than those of the sensory block.

Intrathecal addition of morphine to bupivacaine is not the cause of postoperative nausea and vomiting.
Postoperative nausea and vomiting after anesthesia is an distressing side effect. This study was undertaken to determine to what extent spinal opioids contribute to postoperative nausea and vomiting (PONV) and secondly to how effectively metoclopramide can reduce the incidence of PONV after intrathecal administration of morphine. ⋯ Administration of metoclopramide did not reduce the overall incidence of PONV. Our study shows no relationship between the use of intrathecal morphine and the incidence of PONV during the first 24 hours postoperative.
