The prevalence of pressure injuries in the intensive care unit (ICU) setting is high with rates ranging from 13.1% to 45.5%. Evaluation of interventions to prevent pressure injuries should be informed by preliminary research to identify factors that should be considered during the design of future trials. The study objectives were to evaluate the process of participant recruitment and monitoring in the ICU; measure the maintenance of body angle (in the side‐lying lateral tilt position) and head and neck alignment angle (in the supine position) among immobile critically ill patients when using a purpose‐designed positioning device and usual care equipment, and; ascertain the time required to position patients with the purpose‐designed positioning device and the usual care equipment. A prospective, observational, feasibility study was conducted in an ICU in Victoria, Australia. The sample was immobile critically ill adults at high‐risk of developing pressure injuries. The usual care interventions were pillows, foam wedges, and rolled towels, and the intervention device was the Z‐Flo Fluidized Positioner. The body angle and head and neck alignment were measured on six occasions (at baseline, 1 hour, and 2 hours). The time required for positioning was also measured. The sample was predominately male (n = 5, 62%) with a mean age of 59 years. The majority of patients (n = 106, 92.2%) were not immobile and therefore were ineligible to participate. A total of 48 turning and positioning interventions were observed. For the side‐lying lateral tilt position, the degree of difference from baseline to 2 hours was no more than three degrees for all the devices (the Fluidized Positioner 25°‐26°, the foam wedge 29°‐27°, and the pillow 23°‐21°). For the head and neck position, the degree of difference from baseline to 2 hours was the greatest for the pillow and rolled towel (78°‐71°, a difference of 7°) and the pillow alone (79°‐74°, a difference of 5°). The degree of difference was the lowest for the Fluidized Positioner (84°‐86°, a difference of 2°). Future research to evaluate positioning equipment in the ICU should consider patient eligibility characteristics, particularly immobility. The conduct of preliminary studies to inform the design of larger pressure injury prevention trials is recommended.
Pressure injuries affect 13.1% to 45.5% of patients in the intensive care unit and lead to pain and discomfort for patients, burden on healthcare providers, and unnecessary cost to the health system. Turning and positioning systems offer improvements on usual care devices, however the evidence of the effectiveness of such systems is still emerging. We conducted an investigator initiated, prospective, single centre, two group, non‐blinded, randomised controlled trial to determine the effectiveness of a system for turning and positioning intensive care unit patients, when compared to usual care turning and positioning devices, for preventing PIs. The trial was prematurely discontinued after enrolment of 78 participants due to COVID‐19 pandemic related challenges and lower than expected enrolment rate. The study groups were comparable on baseline characteristics and adherence to the interventions was high. Four participants developed a PI (in the sacral, ischial tuberosity or buttock region), n = 2 each in the intervention and control group. Each participant developed one PI. As the trial is underpowered, these findings do not provide an indication of the clinical effectiveness of the interventions. There was no participant drop‐out or withdrawal and there were no adverse events, device deficiencies, or adverse device effects identified or reported. The results of our study (in particular those pertaining to enrolment, intervention adherence and safety) provide considerations for future trials that seek to investigate how to prevent PIs among ICU patients.
Introduction: Foreign body aspiration (FBA) is a potentially fatal paediatric emergency. Our objective was to highlight the importance of a multidisciplinary approach to difficult/doubtful diagnosis.
Case Report: 34-month-old girl referred for urgent rigid bronchoscopy after suspected metallic blade ingestion (found chewing on it). She had a previous recurrent history of wheezing. The physical examination revealed face/lip wounds, traces of powder on her teeth but no breathing difficulty. The plain X-Ray revealed radiopaque images of the upper pulmonary field and gastric chamber. In the absence of FBA clinical signs but considering a previous history of bronchial hyperresponsiveness, a direct digital radiographic study was performed. There were no images compatible with foreign bodies: the results were interpreted as artefacts and no bronchoscopy was performed.
Conclusions: A careful pre-anaesthetic evaluation, a high level of suspicion and excellent multidisciplinary communication led to the recognition of false radiologic findings. A conservative approach was followed and invasive procedures in a remote location, with high anaesthetic risk for the paediatric population were avoided.
