    ChatGPT and pediatric advanced life support: A performance evaluation
    (Elsevier Ireland Ltd, 2024) Kokulu, Kamil; Demirtaş, Mehmet Semih; Sert, Ekrem T.; Mutlu, Hüseyin
    The development of artificial intelligence (AI) tools, such as large language models (LLMs), holds significant promise for enhancing patient care and medical education. ChatGPT (Chat Generative Pre-trained Transformer), an LLM developed by OpenAI utilizing the GPT-4 architecture, currently demonstrates the highest level of medical domain knowledge among its peers.1 While ChatGPT’s performance has been assessed in various medical examinations,2,3 its capabilities in pediatric resuscitation and advanced life support remain unexplored. This study aimed to evaluate the clinical reasoning ability of ChatGPT by testing its performance on the American Heart Association (AHA) Pediatric Advanced Life Support (PALS) exam.

    Determination of the Cricothyroid Membrane Height by Age and Sex and Optimal Tracheal Tube Size
    (John Wiley and Sons Inc, 2024) Kokulu, Kamil; Alkan, Ender; Sert, Ekrem T.; Mutlu, Hüseyin; Türkücü, Çağrı; Akar, Emin H.
    The primary aim of this study was to determine the average cricothyroid membrane (CTM) height in healthy volunteers, and the secondary aim was to determine the hypothetical success rate for emergency cricothyrotomy with a tracheal tube with an 8.0 mm outer diameter. Methods: This study included healthy volunteers aged 18 years and older. The participants' clinical characteristics were recorded, and their CTM height was measured using ultrasound, with their necks placed sequentially in the neutral and extension positions. The relationship between the CTM height and sex, age, height, weight, body mass index, and sternomental distance was evaluated using linear regression analysis. An equation that could estimate the height of the CTM was obtained with the parameters found significant in this analysis. Results: Of the 340 participants, 208 (61.2%) were male. The mean (SD) height of the CTM in the extension position was 9.60 (1.54) mm, and it was significantly shorter in the women than in the men (8.72 [1.19] mm vs. 10.16 [1.48] mm, p < 0.001). Among the participants of short stature, the CTM was significantly shorter, regardless of sex. The hypothetical success rate for emergency cricothyrotomy was 93.3% for the males and 73.5% for the females. The equation for estimating the height of the CTM in the extension position was determined as ?4.36 + 5.27 × height (m) + 0.32 × sternomental distance (cm). Conclusions: Since the CTM height may differ according to age, sex, and height, cricothyrotomy sets should be available in various outer diameters.
