Observational Study
The TotaltrackTM video laryngeal mask: an evaluation in 300 patients.
The TotaltrackTM is a new video laryngeal mask, which combines a supraglottic airway with a videolaryngoscope. We evaluated the performance of this device in an observational study in 300 adult patients. The Totaltrack was inserted at the first attempt and the glottis seen in all cases. ⋯ The median time to visualisation of vocal cords, to confirmation of ventilation and to successful tracheal intubation was 5 s, 13 s and 24 s, respectively. Nineteen patients (6.3%; 95%CI 3.55-9.05%) suffered minor complications, such as mucosal lesion or blood staining. The Totaltrack appears effective for airway management.

Airway management research: what problem are we trying to solve?

Blood transfusion is given according to haemoglobin thresholds aimed at restoration of arterial oxygen-carrying capacity. Patient survival after severe haemorrhagic shock depends on restoration of microvascular perfusion, tissue oxygen delivery, endothelial function and organ integrity. We investigated a novel crystalloid fluid designed for tissue oxygen delivery, Oxsealife® , with components that generate microvascular nitric oxide and scavenge reactive oxygen species generated during ischaemia-reperfusion injury. ⋯ Serum markers of organ function, animal activity during recovery and histological analysis of tissue morphology and endothelial glycocalyx integrity confirmed functional recovery from haemorrhagic shock. We conclude that recovery of tissue oxygen delivery and organ function after haemorrhagic shock may not be dependent on treatments that increase haemoglobin levels. Oxsealife shows promise for treatment of severe haemorrhagic shock and may reduce the requirement for allogeneic blood products.
