Background Few data exist on high flow nasal cannula (HFNC) use in patients with acute respiratory failure (ARF) admitted to general wards. Rationale and objectives To retrospectively evaluate feasibility and safety of HFNC in general wards under the intensivist-supervision and after specific training. Methods Patients with ARF (dyspnea, respiratory rate-RR > 25/min, 150 < PaO2/FiO2 < 300 mmHg during oxygen therapy) admitted to nine wards of an academic hospital were included. Gas-exchange, RR, and comfort were assessed before HFNC and after 2 and 24 h of application. Results 150 patients (81 male, age 74 [60–80] years, SOFA 4 [2–4]), 123 with de-novo ARF underwent HFNC with flow 60 L/min [50–60], FiO2 50% [36–50] and temperature 34 °C [31–37]. HFNC was applied a total of 1399 days, with a median duration of 7 [3–11] days. No major adverse events or deaths were reported. HFNC did not affect gas exchange but reduced RR (25–22/min at 2–24 h, p < 0.001), and improved Dyspnea Borg Scale (3–1, p < 0.001) and comfort (3–4, p < 0.001) after 24 h. HFNC failed in 20 patients (19.2%): 3 (2.9%) for intolerance, 14 (13.4%) escalated to NIV/CPAP in the ward, 3 (2.9%) transferred to ICU. Among these, one continued HFNC, while the other 2 were intubated and they both died. Predictors of HFNC failure were higher Charlson’s Comorbidity Index (OR 1.29 [1.07–1.55]; p = 0.004), higher APACHE II Score (OR 1.59 [1.09–4.17]; p = 0.003), and cardiac failure as cause of ARF (OR 5.26 [1.36–20.46]; p = 0.02). Conclusion In patients with mild-moderate ARF admitted to general wards, the use of HFNC after an initial training and daily supervision by intensivists was feasible and seemed safe. HFNC was effective in improving comfort, dyspnea, and respiratory rate without effects on gas exchanges. Trial registration This is a single-centre, noninterventional, retrospective analysis of clinical data.
Background: Liver bleeding secondary to haemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome is uncommon, but a life-threatening peripartum condition that needs a prompt multidisciplinary approach.Case Presentation: In this study, we presented a case of 28-year-old pregnant woman, who was presented to the obstetrics department with signs of preeclampsia and foetal growth restriction. An emergency caesarean section was performed, and the patient developed a HELLP syndrome complicated by spontaneous liver rupture. After radiological and surgical procedures, liver failure became evident and liver transplantation was successfully performed. The patient and her daughter are now alive.Conclusions: Despite the rarity of this disease, liver complications due to HELLP syndrome must be properly diagnosed and treated given the gravity of the possible evolution in young women. After diagnosis, the patients must be treated in specialised centres with gynaecological, liver surgery, and transplant skills.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
