To assess the value of ProSeal-LMA (laryngeal mask airway) during hip replacement operation. Sixty patients undergoing hip replacement operation were randomly divided into two groups with 30 cases in each. ProSeal-LMA was applied in Group I and normal endotracheal tube in Group II. The parameters of heart rate (HR), mean arterial blood pressure (MAP), partial pressure of carbon dioxide in end expiratory gas (PetCO2) and airway pressure (Paw) were monitored and recorded in both groups at time points of before and after placing ProSeal-LMA or tracheal tube, body turning-over, skin incision and extubating of ProSeal-LMA or tracheal tube. And also the cases with airway complications were reported. There was no significant changes of HR and MAP in Group I at time points of placing and extracting ProSeal-LMA (P > 0.05). However, there was significant difference of HR and MAP in Group II at time points of placing and extracting tracheal tube (P < 0.05), And it was significantly higher than that in Group I at the same time point (P < 0.05). No significant difference of these parameters was observed at other time points (P > 0.05). And also PetCO2 and Paw were not changed significantly between two groups at time points of before and after body turning over (P > 0.05). ProSeal-LMA can be applied in hip replacement operation because of its simple handling, lesser effects upon respiration and circulation and fewer post-operative complications.
