Biography Historical ArticleTribute to Dr. Takuo Aoyagi, inventor of pulse oximetry.
Dr. Takuo Aoyagi invented pulse oximetry in 1974. Pulse oximeters are widely used worldwide, most recently making headlines during the COVID-19 pandemic. Dr. Aoyagi passed away on April 18, 2020, aware of the significance of his invention, but still actively searching for the theory that would take his invention to new heights. ⋯ Dr. Aoyagi's final wish was to find a theory of pulse oximetry. We hope this tribute to him and his invention will inspire a new generation of scientists, clinicians, and related organizations to secure the foundation of the theory.

Case ReportsUnique strategy using a standard double lumen tube during one lung ventilation for successful intraoperative airway management in patients with a giant bulla on the ventilated side: case series.
Giant lung bullae are usually seen in patients with severe chronic obstructive pulmonary disease. Over time, air trapping leads to severe dyspnea and CO2 accumulation. In severe cases, overinflation and rupture of the bulla can cause secondary life-threatening tension pneumothorax. ⋯ Through this experience, to avoid further overinflation, we devised an original, unique and simple airway management strategy using a standard double lumen tube (DLT), which only requires slightly deeper advancement of the DLT to achieve selective lobar blockade during one lung ventilation (OLV). Following the first case, we used this strategy in a 48-year-old male patient who underwent left giant bullectomy, resulting in successful airway management without overinflation during OLV. We recommend our strategy as an option for successful intraoperative airway management during OLV in select bullectomy patients with bilateral giant bullae.

Review Meta AnalysisComparison of PECS II and erector spinae plane block for postoperative analgesia following modified radical mastectomy: Bayesian network meta-analysis using a control group.
The present study compared the effects of pectoral nerve block II (PECS II) and erector spinae plane (ESP) block for postoperative analgesia in patients who underwent modified radical mastectomy by performing a network meta-analysis (NMA) using indirect comparison with systemic analgesia. Studies comparing the analgesic effects of PECS II and ESP block were searched on MEDLINE, PubMed, EMBASE and the Cochrane Library. The primary outcome of this study was cumulative opioid consumption for 24 h postoperatively. ⋯ Relative to systemic analgesia, PECS II block showed lower pain scores over the first postoperative 24 h, whereas ESP block did not. PECS II block showed the highest surface under the cumulative ranking curves for both opioid consumption and pain score. Both PECS II and ESP blocks were shown to be more effective than systemic analgesia regarding postoperative analgesia following modified radical mastectomy, and between the two blocks, PECS II appeared to have favorable analgesic effects compared to ESP block.

Observational StudyOpioid prescription-use after cesarean delivery: an observational cohort study.
To evaluate current opioid prescription practices following a cesarean delivery. ⋯ Women were prescribed excess opioids. Excess opioids accounted for 63.3% of all pills filled, a total of 1670 pills leftover, most of which were stored in an unlocked location (75.6%). Our data showed a discrepancy of pills prescribed (24) compared to those used (10), which was also perceived as enough or too many by our participants. Our study demonstrates that women would benefit from fewer opioid pills and a discussion based on their pain perception.
