Application of i-gel laryngeal mask combined with T-seal adapter in painless bronchoscopy / 实用医学杂志

ABSTRACT

Objective To observe the clinical effect of controlled ventilation with i-gel laryngeal mask airway in painless bronchoscopy. Methods 80 patients were randomly divided into control group (group A, n =40) and surface anesthesia group (group B, n = 40). Fent-anyl, ruifentanyl, propofol, succinylcholine anesthesia and controlled ventilation was adopted by i-gel laryngeal mask combined with T-seal adapter in control group.Surface of lidocaine anesthesia, spontaneous breathing, nasal cannula oxygen were applied in surface anesthesia group. Patients vital signs change in bronchoscopy , endoscopic related adverse reactions such as body movement, cough, laryngospasm. anesthesia related adverse reactions such as postoperative bucking, choking hoarseness, examination time and patient satisfaction were recorded. Results Controlled ventilation with i- gel laryngeal mask shows airway changes are small (P < 0.05), and less adverse reaction (P < 0.05). Patients showed higher satisfaction (P < 0.05). Conclusion controlled ventilation with i-gel laryngeal mask in painless bronchoscopy is safe , controls the airwayeffectively , and solve the problem of respiratory depression , which proves to be a feasible method.
