Abstract
ABSTRACT The selection of different examination sequences of painless gastroscopy in patients with difficult airway risk was explored in this study. A total of 45 patients undergoing painless gastroscopy with Mallampati airway score of III-IV were randomly assigned into two groups (A group and B group) according to the sequence of colonoscopy and gastroscopy. Group A was first examined by gastroscopy after anesthesia, and then by colonoscopy. Group B was examined in the opposite order, first by colonoscopy, and then by gastroscopy. Ramsay Sedation scores were evaluated every five minutes when gastroscopy was performed in the two groups. The dosage of propofol, blood pressure, heart rate, blood oxygen saturation, recovery time, hospital leaving time, and adverse reactions after induction and endoscopy were recorded. The dosage of propofol and change of vital signs in B group was less than that in A group. Operation time, recovery time, hospital leaving time and postoperative adverse reactions have no significant difference between two groups. For patients at risk of difficult airway, colonoscopy followed by gastroscopy has more stable intraoperative vital signs and less propofol consumption.
