Patients undergoing ambulatory surgery under general anesthesia experience considerable levels of postoperative nausea and vomiting (N/V) after their discharge. However, those complications have not been thoroughly investigated in hand surgery patients yet. We investigated factors associated with postoperative N/V in patients undergoing an ambulatory hand surgery under general anesthesia and determined whether patients' satisfaction with this setting is associated with postoperative N/V levels. ⋯ Although most of the patients were satisfied with the ambulatory surgery setting, moderate to high levels of N/V were associated with dissatisfaction of patients with this setting, suggesting a need for better identifying and managing those patients at risk. The information regarding risk factors for N/V could help in preoperative patient consultation regarding an ambulatory hand surgery under general anesthesia.

To determine relative fixation strengths of a single lateral locking plate, a double construct of a locking plate, and a tibial nail used in treatment of proximal tibial extra-articular fractures. ⋯ During biomechanical testing of a simulated comminuted proximal tibial fracture model, the DP proved to be stronger than the LP in terms of ultimate strength. IN proved to be the strongest; however, for minimally invasive osteosynthesis, which may be technically difficult to perform using a nail, the performance of the DP construct may lend credence to the additional use of a medial locking plate.

Distal radius fracture is the most common fracture of the upper extremity, and approximately 60,000 distal radius fractures occur annually in Korea. Internal fixation with an anatomical volar locking plate is widely used in the treatment of unstable distal radius fractures. However, most of the currently used distal radius anatomical plate systems were designed based on the anatomical characteristics of Western populations. Recently, the Korean-type distal radius anatomical volar plate (K-DRAVP) system was designed and developed based on the anatomical characteristics of the distal radius of Koreans. The purpose of this study was to evaluate the preliminary results of the new K-DRAVP system, and to compare its radiologic and functional results with those of the other systems. ⋯ The newly developed K-DRAVP system could be used to restore and maintain good anatomical parameters, and provide good clinical outcomes with low complication rates. This system is a promising surgical option for the treatment of distal radius fractures in the Korean population.

The purpose of this study was to evaluate the clinical feasibility of an electric nerve stimulator in a lumbar transforaminal epidural block. ⋯ A nerve stimulator can help to predict the accuracy of needle positioning as a supplemental aid for a successful lumbar transforaminal epidural block. It is sufficient to initiate a proper stimulation amplitude of the nerve at 2 mAh.

Hemiarthroplasty is a common operation to treat femoral neck fracture in elderly patients. The choice of whether to use cemented stem or cementless stem in hemiarthroplasty has been controversial in clinical practice. However, recent trends regarding stem choice in South Korea are not known or documented. In this study, we assessed the trends of stem fixation in hemiarthroplasty for femoral neck fractures in South Korea. ⋯ There was a current trends towards using cementless stems in hemiarthroplasty for femoral neck fractures in South Korea.
