Epidural anatomy examined by cryomicrotome section. Influence of age, vertebral level, and disease.
Cryomicrotome section is a means of anatomic examination with minimal artifact ideally suited to delineating details of tissue relationships in the epidural space. In the past, healthy adult lumbar levels have been studied by this method. This report extends observations to other regions of the vertebral column, other age groups, and some abnormal conditions. ⋯ Variations in epidural anatomy due to vertebral level, age, and disease may alter the ease of epidural entry and passage of catheters and injected solution.

Comparative Study Clinical Trial Controlled Clinical TrialPostdural puncture headache and back pain after spinal anesthesia with 27-gauge Quincke and 26-gauge Atraucan needles.
The purpose of this study was to determine whether the 26-gauge Atraucan needle shows any benefit on the incidence of postdural puncture headache (PDPH) and back pain as compared with the 27-gauge Quincke needle. ⋯ Both needles are associated with very low incidences of PDPH and back pain, which are not affected by which needle is chosen.

Clinical TrialAnalgesic efficacy and side effects of subarachnoid sufentanil-bupivacaine administered to women in advanced labor.
Previous studies of labor analgesia using subarachnoid sufentanil (alone or with adjuvants) have focused on women in the early first stage of labor. This study prospectively evaluated analgesia and side effects of subarachnoid sufentanil (10 micrograms) plus bupivacaine (2.5 mg) in parturients with cervical dilation of 7 cm or more. ⋯ In parturients with cervical dilation of 7 cm or more, subarachnoid sufentanil-bupivacaine produces rapid analgesia with an effective duration of approximately 130 minutes.

Celiac plexus block. Retrocrural computed tomographic anatomy in patients with and without pancreatic cancer.
Neurolytic celiac plexus block is often performed for analgesia from pancreatic cancer, but it is not known if the cancer alters the anatomy relevant to the successful performance of retrocrural celiac plexus block. ⋯ The predicted success of stimulated retrocrural celiac plexus block differed between patients with and without pancreatic cancer. These findings have implications for the performance of celiac plexus block.

Safety of spinal and epidural anesthesia in parturients with chorioamnionitis.
The safety of spinal and epidural anesthesia in patients with chorioamnionitis was explored. ⋯ Conduction anesthesia may be safe in parturients with chorioamnionitis without prior antibiotic therapy.
