ABSTRACT
The serious problem faced by the world now is the pandemic caused by Covid-19. Currently, body temperature and olfactory screening are still important, especially for safety in closed rooms. This study aims to design and build a simple prototype of an automatic door integrated with contactless temperature and olfactory detection devices. This device consists of an MLX 90614 sensor as a temperature detector, an IR FC-51 sensor as a fragrance object detector, an Arduino UNO as a processor, and an LED display that displays instructions and screening results. The door automatically opens if the temperature and smell are normal and vice versa. The implementation results of this prototype provide the best detection distance of up to 2.5 centimeters with 5% error. While the FC-51 sensor is able to detect up to a distance of 5 centimeters. The performance of the MLX 90614 sensor in detecting temperatures is not significantly different from the detection results of the GXGOI thermogun, which is only around 0.17 degrees Celsius. In general, the entire device part works as expected with 100% accuracy. This simple prototype is expected to inspire screening techniques to prevent the spread of Covid19 in closed rooms. © 2022 IEEE.
ABSTRACT
Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-also known as 2019 novel coronavirus or COVID-19-first emerged on December 31, 2019 in China, and has since rapidly spread to become a world-wide pandemic. Orthopaedic trauma services, have maintained a significant portion of their previous volume throughout the pandemic, specifically, hip fractures in the elderly population.Intertrochanteric fracture is one of the most common injuries among the elderly and is associated with a high mortality rate within 30 days after the injury event.Treatment of Intertrochanteric fractures during the coronavirus disease 2019 (COVID-19) pandemic has posed unique challenges for the management of COVID-19infected patients and the maintenance of standards of care. PFNA2 provide stability, compression as well as rotational control of the fracture and allows early post operative mobilization, weight bearing and thereby early fracture union. This study aims to assess the functional outcome of intertrochanteric fracture treated by PFNA2 in COVID-19-positive patients. Objectives: To evaluate the functional outcome of intertrochanteric fracture treated by PFNA2 in COVID-19-positive patients: a retrospective study Methodology: This was a retrospective study of 30 patients,18 females and 12 males ≥55 years of age with intertrochanteric fracture and COVID-19 who underwent operative management with PFNA2. Clinical characteristics and early postoperative outcomes were reported. Results: A total of 30 patients, 21 patients (70%) had fever, cough, and fatigue at the time of presentation. 9 patients (30%) had sore throat and dyspnea, headache and dizziness (23%) (7 patients), abdominal pain and vomiting (16%) (5 patient), chest pain and nasal congestion (10%) (3 patient).18 patients (60%) had comorbidities. Postoperatively all 30 patients (100%) required non-invasive mechanical ventilation. All patients (100%) were given antibiotic therapy,18 patients underwent anti thromboembolic prophylaxis. 20 patients were treated with corticosteroids. Blood transfusion was done in 14 patients. Average HARRIS HIP SCORE was 83.6 at the end of six months graded as good outcome. The length of hospital stay in our study was 10 days (7-14 days). The complications in our study included bed sores, superficial and (which settled subsequently with Intravenous antibiotics and debridement respectively). Conclusions: Our study shows that intertrochanteric fracture patients who present with a mild to moderate COVID-19 symptoms who underwent Intertrochanteric fracture surgeries with PFNA2 had a good functional outcome with few post op complications.
ABSTRACT
OBJECTIVE: The coronavirus disease 2019 pandemic poses major risks to health care workers in neurocritical care. Recommendations are in place to limit medical personnel attending to the neurosurgical patient as a protective measure and to conserve personal protective equipment. However, the complexity of the neurosurgical patient proves to be a challenge and an opportunity for innovation. The goal of our study was to determine if telemedicine delivered through smart glasses was feasible and effective in an alternative method of conducting ward round on neurocritical care patients during the pandemic. METHODS: A random pair of neurosurgery resident and specialist conducted consecutive virtual and physical ward rounds on neurocritical patients. A virtual ward round was first conducted remotely by a specialist who received real-time audiovisual information from a resident wearing smart glasses integrated with telemedicine. Subsequently, a physical ward round was performed together by the resident and specialist on the same patient. The management plans of both ward rounds were compared, and the intrarater reliability was measured. On study completion a qualitative survey was performed. RESULTS: Ten paired ward rounds were performed on 103 neurocritical care patients with excellent overall intrarater reliability. Nine out of 10 showed good to excellent internal consistency, and 1 showed acceptable internal consistency. Qualitative analysis indicated wide user acceptance and high satisfaction rate with the alternative method. CONCLUSIONS: Virtual ward rounds using telemedicine via smart glasses on neurosurgical patients in critical care were feasible, effective, and widely accepted as an alternative to physical ward rounds during the coronavirus disease 2019 pandemic.
