Effect of Different Water Injection Temperatures on the Safety and Comfort of Patients Undergoing Ultrasound Endoscopy of Small Probes Under Intravenous Anesthesia
Small probe endoscopy is currently the best way to diagnose submucosal lesions of the digestive tract. Ultrasonic endoscopy of small probes requires filling the probe and the air in the lumen with water to eliminate gas. Water injection may cause patients with nausea and vomiting, choking cough, abdominal pain, bloating and other uncomfortable symptoms, and in severe cases, it may cause adverse consequences such as breath holding, arrhythmia, and increased blood pressure. At present, some studies have improved patient discomfort by changing the water injection method and developing new acoustic media during the ultrasonic endoscopy of small probes. At present, there are no studies on the impact of different water injection temperatures on the safety and comfort of patients undergoing small probe ultrasound endoscopy under intravenous anesthesia.
In order to improve patient comfort and cooperation, the vast majority of patients currently undergo ultrasound endoscopy under intravenous anesthesia. Under the action of anesthesia and sedative drugs, the patient's thermoregulation center is inhibited, and the change of external temperature is often more obvious to the patient's hemodynamics. Previous studies have found that the temperature of ingested water has an effect on human hemodynamics, digestive tract peristalsis, and visceral body temperature receptors. Injection of relatively low temperature water may reduce the patient's cardiopulmonary load, delay gastrointestinal motility, and shorten the duration of examination; Injecting room or center temperature water may reduce patient coldness and improve patient comfort. Therefore, it is interesting to explore the effects of different water injection temperatures on the safety and comfort of patients with small probe ultrasound endoscopy under intravenous anesthesia, and aim to identify an optimal water injection temperature that can ensure the safety of patient examination and improve patient comfort.
