Randomized Controlled Trial Comparative Study Clinical TrialIntravenous lidocaine versus thoracic epidural analgesia: a randomized controlled trial in patients undergoing laparoscopic colorectal surgery using an enhanced recovery program.
Laparoscopy, thoracic epidural analgesia, and enhanced recovery program (ERP) have been shown to be the major elements to facilitate the postoperative recovery strategy in open colorectal surgery. This study compared the effect of intraoperative and postoperative intravenous (IV) lidocaine infusion with thoracic epidural analgesia on postoperative restoration of bowel function in patients undergoing laparoscopic colorectal resection using an ERP. ⋯ Intraoperative and postoperative IV infusion of lidocaine in patients undergoing laparoscopic colorectal resection using an ERP had a similar impact on bowel function compared with thoracic epidural analgesia.

Randomized Controlled Trial Comparative StudyIs circumferential injection advantageous for ultrasound-guided popliteal sciatic nerve block?: A proof-of-concept study.
Ultrasound (US) guidance, in some instances, can increase the success rate and reduce the onset and procedure times for peripheral nerve blockade compared with traditional nerve localization techniques. The presumptive mechanism for these benefits is the ability to accurately inject local anesthetic circumferentially around the target nerve. We aimed to determine whether ensuring circumferential spread of local anesthetic is advantageous for US-guided popliteal sciatic nerve block. ⋯ Ultrasound-guided circumferential injection of local anesthetic around the sciatic nerve at the popliteal fossa can improve the rate of sensory block without an increase in block procedure time or block-related complications compared with a single-location injection technique.

GuidelineGuidelines for fellowship training in Regional Anesthesiology and Acute Pain Medicine: Second Edition, 2010.
The Regional Anesthesiology and Acute Pain Medicine Fellowship Directors Group develops and maintains guidelines for fellowship training in the subspecialty. These guidelines update the original guidelines that were published in 2005. The guidelines address 3 major topic areas: organization and resources, the educational program, and the evaluation process.

Comparative StudyMorphologic study of nerve root and types of needle used in transforaminal injections.
The bevel type and location of the distal orifice of the needle may have relevance for potential complications occurring during transforaminal epidural injection. ⋯ The layer of fat around nerve roots may prevent the contact of the needle tip with axons. The sharp needle tip entered the nerve root cuff more easily than the blunt tip in the cadaveric nerve root samples, measured in a qualitative manner. There is a need for clinical studies to ascertain if blunt needles may be safer than sharp needles for transforaminal injections.

ReviewNeedle to nerve proximity: what do the animal studies tell us?
Recent animal studies have provided insight and understanding, as well as promising clinical tools, to help identify needle-to-nerve contact and potentially hazardous intraneural injection. This narrative review describes and summarizes the contemporary animal studies primarily relating to indicators of needle-to-nerve contact and intraneural injection. Resultant nerve injury, whenever sought, is discussed.
