It is not easy to ensure optimal prevention of hospital‐acquired pressure ulcer (HAPU) in crowded emergency departments (EDs). We hypothesised that a prolonged ED length of stay (LOS) is associated with an increased risk of HAPU. This is a single‐centre observational study. Prospectively collected HAPU surveillance data were analysed. Adult (aged ≥20 years) patients admitted through the ED from April 1, 2013 to December 31, 2016 were included. The primary outcome was the development of HAPU within a month. Covariates included demographics, comorbidities, conditions at triage, initial laboratory results, primary ED diagnosis, critical ED interventions, and ED dispositions. The association between ED LOS and HAPU was modelled using logistic and extended Cox regression. A total of 48 641 admissions were analysed. The crude odds ratio (OR) and hazard ratio (HR) for HAPU were increased to 1.44 (95% CI, 1.20‐1.72) and 1.21 (95% CI, 1.02‐1.45), respectively, in ED LOS ≥24 hours relative to ED LOS <6 hours. In multivariable logistic regression, ED LOS ≥12 and ≥24 hours were associated with higher risk of HAPU, with ORs of 1.30 (95% CI, 1.05‐1.60) and 1.80 (95% CI, 1.45‐2.23) relative to ED LOS <6 hours, respectively. The extended Cox regression showed that the risk lasted up to a week, with HRs of 1.42 (95% CI, 1.07‐1.88) and 1.92 (95% CI, 1.44‐2.57) relative to ED LOS <6 hours, respectively. In conclusion, Prolonged ED LOS is independently associated with HAPU. Shorter ED LOS should be pursued as a goal in a multifaceted solution for HAPU.

ObjectiveThe Valsalva maneuver is recognized as an effective method to dilate the internal jugular vein (IJV). However, this maneuver cannot be performed in many cases, such as children and unconscious patients. The aim of this study was to evaluate the effectiveness of proximal IJV compression, which can easily be performed, regardless of patient cooperation.MethodsHealthy adult volunteers were recruited from tertiary hospital employees. Basic anatomic and physiologic data were collected. The subjects lay down as if they were undergoing IJV catheter insertion, in the supine position with their necks turned 30 degrees to the left. The main outcome was the cross-sectional area (CSA) of the distal IJV as measured by ultrasound in four stages. The first stage was sham without any maneuver. The second was Valsalva maneuver, the third was digital IJV compression, and the fourth was digital compression accompanied by simultaneous Valsalva maneuver.ResultsA total of 41 volunteers were enrolled. Twenty-six (63.41%) were male with an average age of 28.15±2.85 years. Mean height was 170.74±8.66 cm and mean neck circumference was 35.28±3.87 cm. The mean CSA-IJV was 1.06±0.36 cm2 without any maneuver. It increased to 1.34±0.45 cm2 with Valsalva maneuver (P<0.001), to 1.26±0.41 cm2 with digital compression (P<0.001), and to 1.41±0.47 cm2 with the two maneuvers combined (P=0.01).ConclusionDigital proximal IJV compression effectively dilates the distal IJV. When performed simultaneously with the Valsalva maneuver, the effect was enhanced.

Maxillofacial trauma occasionally presents a serious challenge for physicians, and an orofacial injury can be considered life-threatening. It is difficult to control the bleeding and prevent airway obstruction simultaneously with conventional treatment. Herein, we share two cases in which we managed massive orofacial bleeding using a King laryngeal tube, a supraglottic airway device equipped with an inflatable balloon. Both patients had uncontrolled orofacial bleeding. In one of the patients, endotracheal intubation was possible; however, bleeding continued, and vital signs became unstable. The second patient had failed endotracheal intubation due to uncontrolled bleeding. We deployed the King laryngeal tube in both patients and achieved bleeding control and airway maintenance. Both patients were discharged without complications after 3 to 4 weeks. The King laryngeal tube method can be considered a useful management option for addressing massive orofacial bleeding that is uncontrollable with conventional treatment.
