I-gel® as airways management in a challenging adult tracheobronchial foreign body aspiration.

Tracheobronchial foreign body (TFB) aspiration is an uncommon but potentially life-threatening event. This case report discusses the successful extraction of a metallic screw aspirated by a 48-year-old woman with intellectual disability, using flexible bronchoscopy through the i-gel® laryngeal mask under general anesthesia. The i-gel® device proved effective in maintaining airway access and facilitating bronchoscopy, emphasizing its utility in challenging cases. The report underscores the significance of careful assessment, skillful intervention, and multidisciplinary teamwork in managing TFB aspirations, especially in uncooperative patients with comorbidities.

Type B aortic dissection residual after proximal aortic repair: an innovative open surgical approach in patients not eligible for endovascular treatment.

BACKGROUND: Residual type B aortic dissection (R-TBAD) is a challenging kind of disease affecting an increasing number of patients. Management of R-TBAD has not been specifically addressed in current literature and many of those patients are not eligible for endovascular treatment. Aim of the study was to evaluate the efficacy and feasibility of a specifically conceived procedure the "saguaro branched graft technique" to treat R-TBAD distal to a proximal stent-graft. METHODS: Data of patients treated between 2015 and 2019 were prospectively collected and retrospectively analyzed. Indication for surgery was R-TBAD with chronic malperfusion, aortic enlargement >55 mm or rapid growth, and symptomatic aortic enlargement. A Dacron graft with four branches has been tailored on the back table by implanting two bifurcated grafts to a tube or bifurcated graft. After left thoracoabdominal incision the proximal endograft has been used as a solid starting point for the distal branched graft. Sequential revascularization of the visceral vessels was performed step by step by suturing each artery outside the aneurysm before opening the distal aorta, while a continued retrograde aortic and visceral perfusion was maintained by a left pump atrio-femoral bypass. After that all visceral branches had been regularly perfused from above, the thoraco-abdominal aorta was open and repaired. Outcome measures were 30-day mortality and 30-day major complications as were long-term all-cause mortality, aorta-related mortality, reintervention and patency rates of the branches. RESULTS: Thirteen patients with R-TBAD were treated during the study period. Indication for surgery was chronic malperfusion in one patient (7.7%), aortic enlargement >55 mm or rapid growth in 9 patients (69.2%), persistent pain with aortic enlargement ≥50 mm in 3 patients (23.1%). All patients were considered not eligible for endovascular repair. At 30-days no deaths or re-interventions occurred and major complications including acute cardiovascular events and renal function impairment were not reported; one patient (7.7%) developed postoperative paraplegia. At a mean follow-up period of 19.6±10.2 (range, 8-48) months, reintervention and mortality rates were null. Visceral malperfusion and late-onset renal failure were not reported, and all visceral branches were still patent. CONCLUSIONS: Despite the potential high risk of open surgery, the "saguaro branched graft technique" appears to be a safe surgical solution for R-TBAD.

Propofol or sevoflurane anesthesia without muscle relaxants allow the early extubation of myasthenic patients.

PURPOSE: To compare two non-muscle relaxant anesthetic techniques in myasthenic patients undergoing trans-sternal thymectomy, evaluating the intra- and postoperative conditions including the early extubation in the operating room. METHODS: Sixty-eight consecutive myasthenic patients undergoing trans-sternal thymectomy were prospectively randomized in two groups: propofol and sevoflurane. In both groups anesthesia was induced with propofol (1-2 mg x kg(-1)) and intubation performed after topical anesthesia of the airway with lidocaine. Anesthesia was maintained in the propofol group (36 patients) with a continuous propofol infusion (3-6 mg x kg(-1) x hr(-1)) and nitrous oxide and, in the sevoflurane group (32 patients), with sevoflurane (end-tidal 1-1.5%) in O2:N2O. Intubating conditions, hemodynamic changes, neuromuscular transmission, postoperative intensive care unit and hospital length of stay and complications were evaluated. Data were analyzed with repeated measure two-way analysis of variance (ANOVA), Chi square test and Student's t test. RESULTS: Intubating conditions were good in all patients. There were no hemodynamic changes. All patients were extubated in the operating room and none had to be re-intubated for postoperative respiratory depression. Neuromuscular transmission showed minimal changes, more important in the sevoflurane group, and at the end of the procedure the recovery was complete in all patients. We did not observe any other significant differences between the two groups studied. CONCLUSION: Our data show that these two anesthetic techniques allow the early extubation of myasthenic patients in the operating room.
