A method to estimate the depth of the sciatic nerve during subgluteal block by using thigh diameter as a guide.
The subgluteal approach is common for sciatic nerve block. Although the surface landmarks are clear, the depth of this nerve at this level is difficult to judge. The purpose of this study is to establish a method of estimating the sciatic nerve depth using the anteroposterior (AP) diameter of the thigh as a marker. ⋯ Comparing phase 1 and phase 2 datasets shows the slopes of linear regression lines are nearly parallel. The clinical data from phase 2 verify the anatomical data collected in phase 1 and show that the sciatic nerve depth to AP diameter ratio is 0.43 or the depth of the sciatic nerve is approximately 43% of thigh diameter if the patient is positioned in the lateral decubitus position.

Acute post-surgical pain management: a critical appraisal of current practice, December 2-4, 2005.
The Acute Pain Summit 2005 was convened to critically examine the perceptions of physicians about current methods used to control postoperative pain and to compare those perceptions with the available scientific evidence. Clinicians with expertise in treatment of postsurgical pain were asked to evaluate 10 practice-based statements. The statements were written to reflect areas within the field of acute-pain management, where significant questions remain regarding everyday practice. ⋯ The assigned panel member presented the available evidence, and workshop participants then assigned a category for the level of evidence and recommendation for each statement. All participants then voted about each statement by use of the same accept/reject scale used earlier by ASRA members. This manuscript details those opinions and presents a critical analysis of the existing evidence supporting new and emerging techniques used to control postsurgical pain.
