Clinical Application of Propofol Remifentanial Anesthesis with Laryngeal Mask Airway Ventilation in Old Operative Patients

Objective: To investigate the clinical application effect of target-controlled infusion with propofol remifentanil anesthesia with laryngeal mask airway ventilation in old operative patients. Methods: 127 old operative patients were chosen as research objects. They were randomly divided into A, B and C group. A group: propofol remifentanial anesthesia with laryngeal mask airway ventilation(n=43). B group: propofol anesthesia with laryngeal mask airway(n=42). C group: propofol remifentanial anesthesia with face mask airway ventilation(n=42). Anesthesia was induced by target controlled infusion. Anesthesia induction time, intraoperative reaction,anesthetic effect, sedative effect score, recovery time, recovery quality and incidence of side effect were observed. Results: The dosage of propofol:(335.2±56.4)mg in A group,(466.5±64.8)mg in B group(,334.8±59.7)mg in C group. The difference was statistically significant by analysis of variance(F=6.513, P0.05). Ramsay score: The cases of 6 points were respectively 37 cases(86.0%), 30 cases(71.4%) and 32 cases(81.0%) in A, B and C group. There was significant difference by Chi square(X2=5.832, P0.05). Incidence of side effect: 5 cases(11.6%)in A group,15 cases(35.7%)in B group, 7 cases(16.7%)in C group. There was significant difference by Chi square(X2=7.546, P0.05). Conclusions: The effect of propofol remifentanil anesthesia with laryngeal mask airway ventilation in old operative patients is remarkable. It is safe and effective.
