Objective A new blind intubation device (BID) has been developed for endotracheal intubation. This study aimed to test the usability of the BID in comparison to direct laryngoscopy (DL) and video laryngoscopy (VL) with inexperienced healthcare providers for endotracheal intubation.
Methods This was a randomized crossover simulation study. Participants who had conducted fewer than five live intubation sessions were included in the study. The manikin simulation was conducted using a Laerdal trainer airway manikin. Participants performed intubation using all three devices, DL, VL, and BID. The primary outcome was intubation success rate in the first pass the secondary outcome was intubation time to first ventilation, and the tertiary outcome was dental injury.
Results A total of 45 healthcare workers who were novices in intubation participated in this study, including 13 physicians (interns), 14 emergency medical technicians, and 18 nurses. The intubation success rates in the first pass with BID, DL, and VL were 93.3%, 91.1%, and 97.8%, respectively (P=0.53). The intubation times to first ventilation with BID, DL, and VL were 13.15±6.16, 19.07±7.71, and 17.31±6.57 seconds, respectively (P<0.01). The proportions of dental injuries associated with BID, DL, and VL were 0% for physicians; 28.6%, 14.3%, and 0%, respectively for emergency medical technicians; and 27.8%, 11.1%, and 16.7%, respectively for nurses.
Conclusion We performed a pilot study to test the usability of the new BID. There was no significant difference in intubation success rate in the first pass among BID, DL, and VL. The intubation time to first ventilation was shorter with the BID compared to DL and VL.

Objective To examine the features of powered mobility device-related injuries and identify the predictors of injury severity in such settings.
Methods Emergency Department-based Injury In-depth Surveillance data from 2011 to 2018 were used in this retrospective study. Participants were assigned to the mild/moderate and severe groups based on their excess mortality ratio–adjusted injury severity score and their general injury-related factors and injury outcome-related factors were compared.
Results Of 407 patients, 298 (79.2%) were assigned to the mild/moderate group and 109 (26.8%) to the severe group. The severe group included a higher percentage of patients aged 70 years or older (43.0% vs. 59.6%, P=0.003), injuries incurred in the daytime (72.6% vs. 82.4%, P=0.044), injuries from traffic accidents and falls (P=0.042), head injuries (38.6% vs. 80.7%, P<0.001), torso injuries (16.8% vs. 32.1%, P=0.001), overall hospital admission (28.5% vs. 82.6%, P<0.001), intensive care unit admission (1.7% vs. 37.6%, P<0.001), death after admission (1.4% vs. 10.3%, P=0.034), and total mortality (0.7% vs. 9.2%, P<0.001). The odds ratios (ORs) for injury severity were as follows: age 70 years or older (OR, 2.124; 95% confidence interval [CI], 1.239–3.642), head injury (OR, 10.441; 95% CI, 5.465–19.950), and torso injury (OR, 4.858; 95% CI, 2.495–9.458).
Conclusion The proportions of patients aged 70 years or older, head and torso injuries, injuries from traffic accidents and falls, and injuries in the daytime were higher in the severe group. Our results highlight the need for measures to address these factors to lower the incidence of severe injuries.

Objective Critically ill patients sometimes require transport to another location. Longer intra-hospital transport time increases the risk of hemodynamic instability and associated complications. Therefore, reducing intra-hospital transport time is critical. Our objective was to evaluate whether or not a new device the easy tube arrange device (ETAD) has the potential to reduce intra-hospital transport time of critically ill patients.
Methods We enrolled volunteers for this prospective randomized controlled study. Each participant arranged four, five, and six fluid tubings, monitoring lines, and therapeutic equipment on a cardiopulmonary resuscitation training mannequin (Resusci Anne). The time required to arrange the fluid tubings for intra-hospital transport using two different methods was evaluated.
Results The median time to arrange four, five, and six fluid tubings was 86.00 (76.50 to 98.50), 96.00 (86.00 to 113.00), and 115.50 (93.00 to 130.75) seconds, respectively, using the conventional method and 60.50 (52.50 to 72.75), 69.00 (57.75 to 80.80), and 72.50 (64.75 to 90.50) seconds using the ETAD (all P<0.001). The total duration (for preparing the basic setting and organizing before and after the transport) was 280.00 (268.75 to 293.00), 315.50 (304.75 to 330.75), and 338.00 (319.50 to 360.25) seconds for four, five, and six fluid tubings, respectively, using the conventional method and 274.50 (261.75 to 289.25), 288.00 (271.75 to 298.25), and 301.00 (284.50 to 310.75) seconds, respectively, using the new method (P=0.024, P<0.001, and P<0.001, respectively).
Conclusion The ETAD was convenient to use, reduced the time to arrange medical tubings, and is expected to assist medical staff during intra-hospital transport.

Objective The purpose of this study was to evaluate the effectiveness of a compressive device in controlling hemorrhage following radial artery catheterization.
Methods A prospective randomized trial was conducted on subjects receiving the standard taping method (group S) compared to a compressive device method (group C) after removal of the cannula in radial artery catheterization. Primary outcomes were the success rate of hemostasis and complication rate after cannula removal. Secondary outcomes were the cost of compression and the level of convenience.
Results A total of 250 subjects were enrolled in this study. Hemostasis after removal was successful in 122 of 125 (97.6%) subjects in group S and 116 of 125 (92.8%) subjects in group C (P=0.18). Complication rates in group S and group C were 55.2% (69/125) and 48% (60/125), respectively (P=0.35). The cost of compression for group C (approximately 6,740 Korean won) was approximately two times cheaper than for group S (approximately 14,140 Korean won). The level of convenience was significantly higher in group C than in group S (7.4±2.1 vs. 3.7±1.9,
p < 0.001).
Conclusion These findings suggest that hemostasis using a compressive device may be a suitable alternative method to the standard taping method in controlling hemorrhage following radial artery cannulation.
