The burden of chronic headache disorders in the United States is substantial. Some patients are treatment refractory. Ketamine, an N-methyl-D-aspartate antagonist, provides potent analgesia in subanesthetic doses in chronic pain, and limited data suggest it may alleviate headache in some patients. ⋯ Ketamine was associated with short-term analgesia in many refractory headache patients with tolerable adverse events. A prospective study is warranted to confirm this and elucidate responder characteristics.

Thirty-Day Acute Health Care Resource Utilization Following Outpatient Anterior Cruciate Ligament Surgery.
The need for hospital-based acute care following outpatient surgical procedures is expensive and measured as marker for quality. However, little information is available about events leading to emergency department visit or inpatient admission after ambulatory anterior cruciate ligament (ACL) surgery. ⋯ The rate of hospital-based acute care following outpatient ACL surgery was 3.90%. Many of the events were expected complications related to surgery, such as infection and deep venous thrombosis. However, musculoskeletal pain, drug abuse, and psychotic events featured more prominently than expected. Our findings may direct efforts to address these reasons for seeking acute care after ACL surgery, reduce cost, and improve quality of care.

Pectoral Block Failure May Be Due to Incomplete Coverage of Anatomical Targets: A Dissection Study.
The popularization of ultrasound-guided nerve blocks in cosmetic and reconstructive breast surgery calls for better anatomical understanding of chest wall innervation. When inserting subpectoral implants, pain from pocket dissection, stretching of muscle, and release of costal attachments may be relieved by blocking the pectoral nerves in the interpectoral (IP) space.We describe the variable anatomy of the pectoral nerves in the IP space in order to define the area to be covered for sufficient blockade, based on cadaver dissections. ⋯ The MPN branches that innervate the lower part of the pectoralis major muscle are asymmetrical and variable in location and length; all located in a triangular area easily defined by sonographic landmarks, lateral to the TAA.
