Ultrasound guided tracheal intubation with a styleted tracheal tube in anticipated difficult airway.
Ultrasonography is a simple, reliable, non-invasive technique which helps in real-time assessment of airway anatomy and contributes to safer airway management in various settings like operating rooms, intensive care units and emergency departments. It also helps us to plan the appropriate anesthetic technique especially in difficult airway cases. Here, we discuss the importance of styleted tracheal tube in improving the accuracy of ultrasound guided tracheal intubation in anticipated difficult airway.

Regional cerebral oximetry is consistent across self-reported racial groups and predicts 30-day mortality in cardiac surgery: a retrospective analysis.
Darker skin pigmentation appears to cause underestimation of regional oxygen saturation (rSO2) for certain cerebral oximetry devices. This presents a risk of triggering unindicated interventions and may limit its utility for predicting adverse outcomes. Our goal was to quantify the impact of self-reported race on oximetry measurements during cardiac surgery and elucidate whether race has a mediating role in the association of rSO2 with mortality. ⋯ Mean pre-bypass rSO2 under 63% was an independent predictor of higher 30-day mortality risk (OR: 2.86, CI 1.39 to 5.53, p = 0.003), and the interaction variable between rSO2 and race was not statistically significant (p = 0.299). Cerebral oximetry measurements are more consistent across racial groups than previously reported, supporting its utility for intraoperative monitoring and risk stratification. Pre-intervention rSO2 is associated with increased 30-day mortality at a higher threshold than previously reported and was not significantly impacted by self-reported race.

Artifacts annotations in anesthesia blood pressure data by man and machine.
Physiologic data from anesthesia monitors are automatically captured. Yet erroneous data are stored in the process as well. While this is not interfering with clinical care, research can be affected. ⋯ Artifact detection in physiologic data collected during anesthesia could be automated, but the performance of the learning algorithms in the present study remained moderate. Future research should focus on optimization and finding ways to apply them with minimal manual work. The present study underlines the importance of an explicit definition for artifacts in database research.

Randomized Controlled TrialThe effect of audiovisual distraction on patient-controlled sedation under spinal anesthesia: a prospective, randomized trial.
Audiovisual distraction (AVD) has been used to augment or replace procedural sedation. We investigated whether AVD in patients having total hip (THA) or total knee arthroplasty (TKA) under spinal anesthesia would reduce self-administered propofol consumption during surgery. 50 participants were randomized equally into a patient-controlled sedation (PCS) group or AVD group. All participants were given a spinal block and a propofol PCS device prior to surgery. ⋯ Historical clinician-controlled usage of propofol demonstrated a median of 39.3 mcg/kg/min (29.2-51.2). There were few differences in the secondary outcome measures. The use of AVD did not reduce patient-controlled propofol consumption in patients having a THA or TKA surgery under spinal anesthesia.

Observational StudyPeripheral perfusion index as a predictor of failed weaning from mechanical ventilation.
We hypothesized that impairment of peripheral perfusion index (PPI) during spontaneous breathing trial (SBT) might be predictive of weaning failure. We included 44 consecutive, adult, patients, who were scheduled for weaning after at least 48 h of invasive mechanical ventilation in this prospective observational study. Weaning failure was defined as failed SBT or reintubation within 48 h of extubation. ⋯ Patients with successful weaning showed higher augmentation of PPI during the SBT compared to re-intubated patients. Failure of augmenting the PPI by 41% at the end of SBT could predict re-intubation with negative predictive value of 95%.
