Can EMS providers and emergency department nurses work together to identify home risk factors for falls in older people?

Taiwan is an aging society and the ratio of falls among the older persons is high. Most falls occur at home, and multiple risk factors including home safety are involved. We propose a novel model of emergency medical technicians (EMTs) to assess home safety using scalable checklists. This study was conducted to evaluate its feasibility. This study was conducted between April 1, 2020 and March 31, 2021. The development of the risk factor assessment scale for falls in the home environment was divided into 2 stages. In stage 1, 2 researchers reviewed the extant literature. In stage 2, 6 experts judged the content validity index. According to EMT findings, emergency department (ED) nurses checked the items in the Checklist of Risk Factors for Falls in the Home Environment. The checklists were provided to the geriatric care manager (GCM) in the ED, who then discussed potential solutions with the patients or primary caregivers. A total of 235 participants were enrolled, and EMTs carried out environment assessment for 93.2% (219/235) of them. A total of 207 participants were at risk of falls at home and 79.7% (165/207) of them received intervention measures from the GCM according to the risk items. Education was the main intervention method, with 158 subjects. Moreover, seven subjects (4.2%, 7/165) were provided long-term care resources by the GCM with occupational therapists to help improve the environment at home. Our study provides an efficient method for EMTs to assess home fall hazards.

Non-invasive ventilation for preoxygenation before general anesthesia: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND AND OBJECTIVES: Preoxygenation is crucial for providing sufficient oxygen reservoir to a patient before intubation and enables the extension of the period between breathing termination and critical desaturation (safe apnoea time). Conventionally, face mask ventilation is used for preoxygenation. Non-invasive ventilation is a new preoxygenation method. The study objective was to compare the outcomes of non-invasive ventilation and face mask ventilation for preoxygenation. METHOD: PubMed, Embase, Cochrane Library, and the ClinicalTrials.gov registry were searched for eligible studies published from database inception to September 2021. Individual effect sizes were standardized, and a meta-analysis was conducted using random effects models to calculate the pooled effect size. Inclusion criteria were randomised controlled trials of comparing the outcomes of non-invasive ventilation or face mask ventilation for preoxygenation in patients scheduled for surgeries. The primary outcome was safe apnea time, and the secondary outcomes were post-operative complications, number of patients who achieved the expired O2 fraction (FeO2) after 3 min of preoxygenation, minimal SpO2 during tracheal intubation, partial pressure of oxygen in the arterial blood (PaO2) and partial pressure of carbon dioxide (PaCO2) after preoxygenation, and PaO2 and PaCO2 after tracheal intubation. RESULTS: 13 trials were eligible for inclusion in this study. Significant differences were observed in safe apnoea time, number of patients who achieved FeO2 90% after preoxygenation for 3 min, and PaO2 and PaCO2 after preoxygenation and tracheal intubation. Only in the non-obese subgroup, no significant difference was observed in safe apnoea time (mean difference: 125.38, 95% confidence interval: - 12.26 to 263.03). CONCLUSION: Non-invasive ventilation appeared to be more effective than conventional methods for preoxygenation. We recommend non-invasive ventilation based on our results.

Postpartum ovarian vein thrombophlebitis presenting as vaginal bleeding: A case report.

RATIONALE: Postpartum ovarian vein thrombophlebitis (POVT) is a rare condition, and it can lead to severe complications and mortality. Here we report a patient who presented with vaginal bleeding and the diagnosis of POVT was confirmed by imaging. PATIENT CONCERNS: A 38-year-old postpartum woman without remarkable medical history presented with vaginal bleeding and lower abdominal pain. DIAGNOSES: The diagnosis was confirmed by computed tomography scan marked by a thrombus mass involving the right ovarian vein and inferior vena cava. INTERVENTIONS: The patient was treated with intravenous antibiotics and low-molecular-weight heparin. OUTCOMES: The patient recovered smoothly without complications. LESSONS: We should pay high attention to the recognition and management of POVT to prevent morbidity and mortality.
