ReviewAligning difficult airway guidelines with the anesthetic COVID-19 guidelines to develop a COVID-19 difficult airway strategy: a narrative review.
The coronavirus disease 2019 (COVID-19) pandemic is caused by a coronavirus that is transmitted primarily via aerosol, droplets or direct contact. This may place anesthetists at higher risk of infection due to their frequent involvement in aerosol-generating airway interventions. Many anesthethetic COVID-19 guidelines have emerged, whose underlying management principles include minimizing aerosol contamination and protecting healthcare workers. ⋯ Our article identifies and compares pre-pandemic difficult airway guidelines with the recent anesthetic COVID-19 guidelines. We combine the principles from both sets of guidelines and explain the necessary modifications to the airway guidelines, to form a failed tracheal intubation airway strategy in the COVID-19 patient. Valuing, and a greater understanding of, these differences and modifications may lead to greater adherence to the new COVID-19 guidelines.

Randomized Controlled TrialEffects of spinal anesthesia and sedation with dexmedetomidine or propofol on cerebral regional oxygen saturation and systemic oxygenation a period after spinal injection.
To evaluate changes in cerebral regional oxygen saturation (rSO2) after spinal anesthesia and compare the changes in rSO2 and systemic oxygenation between dexmedetomidine sedation and propofol sedation. ⋯ Spinal anesthesia decreased rSO2; however, the decline was not severe. Dexmedetomidine and propofol did not compromise cerebral oxygenation under spinal anesthesia. Nevertheless, MAP and SpO2 were more stable in dexmedetomidine sedation than in propofol sedation. Dexmedetomidine may be suitable for spinal anesthesia.

Meta AnalysisComparison of colloid and crystalloid using goal-directed fluid therapy protocol in non-cardiac surgery: a meta-analysis of randomized controlled trials.
A few randomized controlled trials (RCTs) have compared crystalloid-based goal-directed fluid therapy (GDFT) with starch-based GDFT in patients undergoing major surgical procedures with conflicting results. In this meta-analysis, colloid-based GDFT was compared with crystalloid-based GDFT. ⋯ Colloids in goal-directed fluid therapy protocol does not offer any benefit over crystalloid-based goal-directed fluid therapy protocol in patients undergoing major non-cardiac surgical procedure.

Randomized Controlled TrialOpen randomized trial of the effects of 6% hydroxyethyl starch 130/0.4/9 and 5% albumin on safety profile, volume efficacy, and glycocalyx degradation in hepatic and pancreatic surgery.
The aim of this study was to evaluate the effects of hydroxyethyl starch (HES) 130/0.4/9 compared to 5% albumin on renal and coagulation safety profiles, volume efficacy and glycocalyx degradation in major abdominal surgery. ⋯ HES 130/0.4/9 can be used as safely and effectively as 5% albumin. Glycocalyx degradation did not differ between use of these solutions in major abdominal surgery.

Evaluation of a new face mask concept for oxygen administration: a crossover study in healthy volunteers.
We developed a new face mask concept for oxygen administration using non-woven textiles. The aim of this study was to evaluate whether the new mask improves acceptability without compromising O2 delivery and CO2 elimination. 10 healthy adult volunteers were randomized to either the conventional plastic face mask-first group or the new face mask-first group. Participants were asked to wear the assigned mask with O2 at 3 L/min for 10 min while seated. ⋯ Median et-O2 with the new mask was 33%, compared with 30% with the conventional mask (P = 0.008). There were no significant differences in et-CO2 by mask type (new, 32 mmHg; conventional, 30 mmHg). In conclusion, the new mask was more comfortable and provided higher et-O2 than the conventional mask.
