Abstract
Endotracheal intubation is a procedure in the care of critically ill patients. Conventional intubation tools have limitations when used in patients who are anticipated to be difficult intubation. The Video-light Intubating Stylet is a device developed to serving as an alternative for patients with predicted difficult airways or limited mouth opening. Objective: To evaluate the success rate of endotracheal intubation using the Video-light Intubating Stylet and to study the hemodynamic changes during intubation. Methods: Case series study, seventy patients aged 18 years and older who underwent elective surgery under general anesthesia with endotracheal intubation at maharat nakhon ratchasima hospital. General anesthesia was induced by intravenous agents and muscle relaxants for intubation, using the Video-light Intubating Stylet. Data recorded included intubation outcomes (success rate, number of attempts, and duration of intubation), blood pressure and heart rate. Results: The majority of the patients were female (58.6%), with a mean age of 50.4 years, mean body weight of 60.7 kg, mean height of 160.2 cm, and mean BMI of 23.6 kg/m². Patients were classified as ASA physical status I, II, and III in proportions of 31.4%, 28.6%, and 40.0%. The overall success rate of intubation was 98.6%, with first, second, and third attempt success rates of 91.4%, 7.1%, and 1.4%. After induction of anesthesia, both blood pressure and heart rate initially decreased, followed by a peak increase immediately after intubation. Subsequently, these values gradually declined and returned to near baseline levels within three minutes after intubation. Conclusion: Endotracheal intubation using the Video-light Intubating Stylet demonstrates a high success rate. The transient increase in blood pressure and heart rate post-intubation remained within acceptable limits and returned to near baseline within three minutes.
