ABSTRACT
Introduction: In a CICO (cannot intubate, cannot oxygenate) situation, anesthesiologists and acute care physicians must be able to perform an emergency surgical cricothyrotomy (front-of-neck airway procedure). CICOs are high-acuity situations with rare opportunities for safe practice. In COVID-19 airway management guidelines, bougie-assisted surgical cricothyrotomy is the recommended emergency strategy for CICO situations. Methods: We designed a 4-hour procedural simulation workshop on surgical cricothyrotomy to train 16 medical residents. We provided prerequisite readings, a lecture, and a videotaped demonstration. Two clinical scenarios introduced deliberate practice on partial-task neck simulators and fresh human cadavers. We segmented an evidence-based procedure and asked participants to verbalize the five steps of the procedure on multiple occasions. Results: Thirty-two residents who participated in the workshops were surveyed, with a 97% response rate (16 of 16 from anesthesiology, 15 of 16 from emergency medicine). Participants commented positively on the workshop's authenticity, its structure, the quality of the feedback provided, and its perceived impact on improving skills in surgical cricothyrotomy. We analyzed narrative comments related to three domains: preparation for the procedure, performing the procedure, and maintaining the skills. Participants highlighted the importance of performing the procedure many times and mentioned the representativeness of fresh cadavers. Discussion: We developed a surgical cricothyrotomy simulation workshop for anesthesiology and emergency medicine residents. Residents in the two specialities uniformly appreciated its format and content. We identified common pitfalls when executing the procedure and provided practical tips and material to facilitate implementation, in particular to face the COVID-19 pandemic.

PURPOSE: During liver transplantation, excessive blood losses are correlated with increased morbidity and mortality. Blood losses are particularly high in the case of urgent liver transplantation for fulminant hepatic failure (FHF). Recombinant activated factor VII (rFVIIa) has shown promise in treating the coagulopathy of liver disease. We review our experience with the use of rFVIIa in treating the coagulopathy of FHF during urgent liver transplantation. CLINICAL FEATURES: We report four patients with FHF who met King's College criteria for liver transplantation and in whom rFVIIa was used after conventional means for treating the associated coagulopathy had failed. In all patients, the coagulation defect was corrected by rFVIIa. However, thrombotic complications occurred in two patients (myocardial ischemia and portal vein thrombosis) and the implication of rFVIIa cannot be excluded. CONCLUSION: We conclude that rFVIIa is effective in the correction of the coagulopathy associated with FHF. However, thrombotic events are of concern and therefore, further studies are warranted to define the safety of rFVIIa in that setting.
