- Background
Red blood cells (RBCs) are a limited resource, and the adverse effects of transfusion must be considered. Multiple randomized controlled trials on transfusion thresholds have been conducted, leading to the establishment of a restrictive transfusion strategy. This study aimed to investigate the status of RBC transfusions in critically ill patients.
Methods
This cohort study was conducted at five university hospitals in South Korea. From December 18, 2022, to November 30, 2023, 307 nontraumatic, anemic patients admitted to intensive care units through the emergency departments were enrolled. We determined whether patients received RBC transfusion, transfusion triggers, and the clinical results.
Results
Of the 154 patients who received RBC transfusions, 71 (46.1%) had a hemoglobin level of 7 or higher. Triggers other than hemoglobin level included increased lactate levels in 75 patients (48.7%), tachycardia in 47 patients (30.5%), and hypotension in 46 patients (29.9%). The 28-day mortality rate was not significantly reduced in the group that received transfusions compared to the non-transfusion group (21.4% vs. 26.8%, P=0.288). There was no difference in the intensive care unit and hospital length of stay or the proportion of survival to discharge between the two groups. The prognosis showed the same pattern in various subgroups.
Conclusions
Despite the large number of RBC transfusions used in contradiction to the restrictive strategy, there was no notable difference in the prognosis of critically ill patients. To minimize unnecessary RBC transfusions, the promotion of transfusion guidelines and research on transfusion criteria that reflect individual patient conditions are required.

- BACKGROUND
The glottis can be exposed by a Glidescope(R) during endotracheal intubation using either the epiglottis or valleculae elevation method. We compared the epiglottis and valleculae elevation methods for endotracheal intubations performed with a Glidescope(R) using differences in success rate, time spent for tracheal intubation and percent of glottic opening.
METHODS
Forty medical students without experience using a Glidescope(R) participated in this prospective, randomized study in which they intubated a tracheal tube into a manikin. All participants performed tracheal intubation using the 2 forementioned methods. Twenty students exposed the vocal cord by placing the blade tip in the valleculae (valleculae elevation method; VEM). The other 20 students directly elevated the epiglottis with the blade (epiglottis elevation method; EEM). We separated intubating time into 3 parts: turnaround time to exposing the vocal cord, tube passing time and first ventilating time.
RESULTS
The success rate of tracheal intubation using VEM (86.7%, 104/120) was higher than that using EEM (65.8%, 79/120) (p < 0.001). VEM resulted in a lower total intubation time (VEM vs. EEM, 23.5 +/- 5.3 vs. 29.0 +/- 8.7, p = 0.001). The key factor of this difference was the tube passing time (VEM vs. EEM, 7.4 +/- 2.5 vs. 12.8 +/- 7.4, p < 0.001).
CONCLUSIONS
Exposing the vocal cord by using VEM during tracheal intubation with a Glidescope(R) can increase the success rate of tracheal intubation and shorten the time of endotracheal intubation in novices.
