Review Meta Analysis Comparative Study
An estimation for an appropriate end time for an intraoperative intravenous lidocaine infusion in bowel surgery: a comparative meta-analysis.
There exists no commonly accepted regimen for an intravenous lidocaine infusion (IVLI). This study aims to determine an appropriate end time for an IVLI during bowel surgery. ⋯ Continuing an IVLI beyond 60 minutes after surgery has no added analgesic or gastrointestinal benefit. Further research is needed to clarify an optimal IVLI regimen and end time.

Randomized Controlled Trial Comparative Study
Ultrasound-guided transversus abdominis plane block in patients undergoing open inguinal hernia repair: 0.125% bupivacaine provides similar analgesic effect compared to 0.25% bupivacaine.
To evaluate the effectiveness of 0.125% bupivacaine compared to 0.25% bupivacaine for ultrasound-guided transversus abdominis plane (TAP) block in patients undergoing open inguinal hernia repair. ⋯ 0.125% Bupivacaine provides similar analgesic effect compared to 0.25% bupivacaine for ultrasound-guided TAP block in patients undergoing open inguinal hernia repair.

Simulation-based learning is emerging as an alternative educational tool in this era of a relative shortfall of teaching anesthesiologists. The objective of the study is to assess whether screen-based (interactive computer simulated) case scenarios are more effective than problem-based learning discussions (PBLDs) in improving test scores 4 and 8 weeks after these interventions in anesthesia residents during their first neuroanesthesia rotation. ⋯ Screen-based simulators were not more effective than PBLD for education during the neuroanesthesia rotation in anesthesia residency.

To investigate the isolated and combined effects of vacuum suctioning and strategic drape tenting on oxygen concentration in an experimental setting. ⋯ Use of a vacuum suction device during surgery will lower local oxygen concentration, and this in turn may decrease the risk of operating room fires. Although strategic tenting of surgical drapes has a theoretical benefit to decreasing the pooling of oxygen around the surgical site, further investigation is necessary before its routine use is recommended.
