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.

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.

Change in staff anesthesiologists' opinions of an Anesthesia Information Management System (AIMS).
Following introduction of an Anesthesia Information Management System (AIMS) at a tertiary care, academic health sciences centre, a quality assurance initiative was conducted to assess staff opinions of the AIMS using a previously published, anonymous survey tool at 1 and 5 years following AIMS introduction. At 5 years compared to 1 year after implementation of AIMS, the majority (18 of 24, 75%) of responses to the survey questions had a statistically significant change (P < 0.05) in the proportion of respondents favoring AIMS compared to the 1 year survey. Domains noted to be more favorable 5 years compared to 1 year after AIMS introduction included patient safety in the Operating Rooms and Post-Anesthesia Care Unit, quality of handover and overall documentation, and communication amongst healthcare workers. The ideal time period at which to assess AIMS after introduction is not clear.

Randomized Controlled TrialValidation of a mobile app for reducing errors of administration of medications in an emergency.
Medication errors occur frequently and are a risk to patient safety. To reduce mistakes in the medication process in emergencies, a mobile app has been developed supporting the calculation of doses and administration of drugs. A simulation study was performed to validate the app as a tool to reduce medication errors. ⋯ The probability of giving an "accurate" dosage was increased from 77.7 (70.9-84.5%) in control scenarios to 93.9 (90-97.8%) in app scenarios. Calculation errors were the main cause for wrong dosing. The app is an appropriate and feasible tool to reduce calculation and handling errors and may increase patient safety.
