Placement of an endotracheal tube is a fundamental procedure in airway management, but novice providers face an increased risk of failure and complications. While using a video laryngoscope (VL) has been shown to enhance success rates, limited evidence exists on whether training with a VL improves success when the procedure is performed with a direct laryngoscope (DL). Objectives This prospective randomized controlled trial aimed to compare the success rates of novice medical students in endotracheal intubation using a DL after training with either VL or traditional training with DL Methods One hundred and thirty novice medical students were randomly assigned to two groups: the VL group (n=65) and the DL group (n=65). After a single training session with their assigned equipment, all students performed one intubation attempt on a manikin using a DL. Results The study found no significant difference in the first-attempt success rate between the VL and DL groups (98.0% vs. 97.7%, p=1.000) However, the VL group demonstrated better full laryngeal visibility (Grade 1 view: 29.4% vs. 27.3%, p=0.030) and higher satisfaction levels (88.2% vs. 72.7%, p=0.039). There were no significant differences in intubation time or dental click events. Conclusions In conclusion, training with a VL provides a clearer visualization of laryngeal structures and enhances satisfaction among medical students when compared to traditional DL training.

Hematocrit (Hct) measurement is a commonly used method for assessing preoperative anemia and guiding blood transfusion decisions. This measurement is primarily performed using standard laboratory instruments. In routine practice, however, centrifugation methods are also used because they are convenient and provide rapid results. Objective: To compare the red blood cell concentration relative to total blood volume (Hematocrit) obtained using a centrifugation method with that obtained using an automated laboratory analyzer. Methods: This was a comparative cross-sectional study with prospective data collection conducted in adult patients aged 18 years and older who underwent surgery at Maharaj Nakhon Ratchasima Hospital. A total of 268 patients were enrolled. Blood samples from each patient were analyzed to determine red blood cell concentration relative to total blood volume using both a centrifugation method and an automated analyzer at the central laboratory. The results from the two methods were compared and statistically analyzed. Results: Hematocrit obtained from the two methods differed; however, the values demonstrated a strong positive linear correlation. The Pearson correlation coefficient was 0.96. The hematocrit measured by the centrifuge had a mean of 34.8 ± 7%, and the hematocrit obtained from the automated analyzer had a mean of 33.1 ± 7%. The mean difference between the two measurement methods was 1.67%. Data with an acceptable level of discrepancy (error less than 4%) accounted for 95.15% of all measurements. Conclusion: Hematocrit obtained from the two measurement methods demonstrated similar trends, with values derived from the centrifugation method tending to be higher than those obtained from the automated analyzer. The observed discrepancy was within an acceptable range.
