Letter Case ReportsPatent ductus arteriosus closure and somatic regional oxyhemoglobin saturation.
The authors report a case of a 14-day-old infant patient with patent ductus arteriosus (PDA) with pulmonary hypertension. Accidental clipping of the left pulmonary artery (LPA) during intended PDA closure was revealed, and subsequent urgent PDA closure and releasing a clip of the LPA were conducted. During surgeries we measured somatic regional oxyhemoglobin saturation (rSO2) values and change in those might be a key for early diagnosis of accidental clipping of the LPA. These findings suggest that we should understand the risk of accidental closure of the LPA during PDA surgery and somatic rSO2 values will provide information for early diagnosis of critical complication.

Endotracheal catheter equipped with functional cuff produces clinically relevant positive end expiratory pressure: a bench study.
Recently, we developed a novel endotracheal catheter with functional cuff (ECFC). Using such an ECFC and a regular ICU ventilator, we were able to generate clinically relevant tidal volume in a lung model and adult human sized animal. This ECFC allows co-axial ventilation without using a jet ventilator. ⋯ With 14 Fr catheter at respiratory rate 20 bpm, PEEP was 0, 3.9, 9.6, 14.6 cmH2O at preset PEEP 0, 5, 10, 15 cmH2O respectively and tidal volume was up to 188.8 ml. With 19 Fr catheter, PEEP was 0, 3.6, 8.9, 13 cmH2O, at preset PEEP 0, 5, 10, 15 cmH2O respectively and tidal volume was up to 345.3 ml. ECFC enables clinicians to generate not only adequate tidal volume but also clinically relevant PEEP via co-axial ventilation using an ordinary ICU ventilator.

ReviewJournal of Clinical Monitoring and Computing 2017/2018 end of year summary: monitoring-and provocation-of the microcirculation and tissue oxygenation.
The microcirculation is the ultimate goal of hemodynamic optimization in the perioperative and critical care setting. In this fourth end-of-year summary of the Journal of Clinical Monitoring and Computing on this topic, we take a closer look at papers published in the last 2 years that focus on this important aspect. ⋯ Additionally, studies on technical differences between NIRS monitors are summarized, as well as studies investigating the feasibility of NIRS monitoring, mainly in the pediatric patient population. Last but not least, novel monitoring tools allow assessing oxygenation at a (sub)cellular level, and those papers incorporating these techniques are also reviewed here.

Practice GuidelinePractice guidelines for the supervising professional: intraoperative neurophysiological monitoring.
The American Society of Neurophysiological Monitoring (ASNM) was founded in 1989 as the American Society of Evoked Potential Monitoring. From the beginning, the Society has been made up of physicians, doctoral degree holders, Technologists, and all those interested in furthering the profession. The Society changed its name to the ASNM and held its first Annual Meeting in 1990. ⋯ Adherence to a literature-based, formalized process characterizes the construction of all ASNM guidelines. The guidelines covering the Professional Practice of intraoperative neurophysiological monitoring were initially published January 24th, 2013, and subsequently that document has undergone review and revision to accommodate broad inter- and intra-societal feedback. This current version of the ASNM Professional Practice Guideline was fully approved for publication according to ASNM bylaws on February 22nd, 2018, and thus overwrites and supersedes the initial guideline.
