Machine learning approaches in predicting ambulatory same day discharge patients after total hip arthroplasty.
With continuing financial and regulatory pressures, practice of ambulatory total hip arthroplasty is increasing. However, studies focusing on selection of optimal candidates are burdened by limitations related to traditional statistical approaches. Hereby we aimed to apply machine learning algorithm to identify characteristics associated with optimal candidates. ⋯ Machine learning algorithm exhibited acceptable model quality and accuracy. Machine learning algorithms highlighted the as yet unrecognized impact of laboratory testing on future patient ambulatory pathway assignment.

Cadaveric investigation of the minimum effective volume for ultrasound-guided suprainguinal fascia iliaca block.
This cadaveric dose-finding study investigated the minimum effective volume of dye in 90% of cases (MEV90), required to stain the femoral, lateral femoral cutaneous and obturator nerves for ultrasound-guided suprainguinal fascia iliaca block (SIFIB). ⋯ For ultrasound-guided SIFIB, the MEV90 of dye required to stain the femoral, lateral femoral cutaneous and obturator nerves is 62.5 mL. Further studies are required to correlate this finding with the MEV90 of local anesthetic in human subjects.

Ultrasound-guided regional anesthesia in the emergency department: an argument for multidisciplinary collaboration to increase access while maintaining quality and standards.
The practice of ultrasound-guided regional anesthesia (UGRA) by emergency medicine physicians in the emergency department (ED) is increasing. The need for effective alternatives to opioid analgesia in the acute care setting likely exceeds the current capacity of UGRA-trained anesthesia teams. ⋯ The sustained interest in UGRA shown by many emergency medicine physicians should be viewed open-mindedly by anesthesiologists. Failure to collaborate on local and national scales could lead to delays in the development and implementation of patient-centered, safe procedural care, and limit patient access to the benefits of regional anesthesia.

Cadaveric study investigating the phrenic-sparing volume for anterior suprascapular nerve block.
This cadaveric study investigated the maximum effective volume of dye in 90% of cases (MEV90), required to stain the suprascapular nerve while sparing the phrenic nerve during the performance of an anterior suprascapular nerve block. ⋯ For ultrasound-guided anterior suprascapular nerve block, the MEV90 of dye required to spare the phrenic nerve is 4.2 mL. Further studies are required to correlate this finding with the MEV90 of local anesthetic in live subjects.
