Application of LMA SupremeTM and SLIPATM laryngeal mask airway in female patients undergoing general anesthesia airway management and related postoperative complications: A retrospective study

Objective　To compare the usage of two kinds of laryngeal mask LMA SupremeTM and SLIPATM in airway management of general anesthesia in adult female patients and the related postoperative complications, so as to provide the basis evidence for guiding the usage of the laryngeal mask airway. Methods　The DoCare anesthesia information management system was used to retrieve the cases of female patients treated with LMA SupremeTM (group L) or SLIPATM (group S) to manage airway during general anesthesia during Oct. 2017 to Mar. 2018. The possibly associated complications occurred during or after operation were recorded after checking the anesthesia information management system. Results　A total of 924 adult female patients were undergone the LMA SupremeTM (379 cases, 41%) or SLIPATM (545 cases, 59%) during operation. The patients came from the department of breast specialist, gynecology, plastic surgery, tumor surgery and other departments. In group L, the size 3# and 4# laryngeal mask were used in proportions of 28.5% and 71.5%, respectively. And in group S, size 49# and 51# laryngeal airway were used in proportions of 86.4% and 13.6%, respectively. There were no details about the possible complications such as pharynx pain associated with the laryngeal mask application in the doctor's record 24 hours after the operation. However, there were 5 cases of hoarseness occurred 24h after operation in group L (1.3%) and 9 cases in group S (1.65%), and 12 cases of risen temperature over 38℃ occurred within 3 days after operation in group L (3.1%), and 19 cases in group S (3.5%). Conclusion　Adult female patients undergone general anesthesia using SLIPATM and LMA SupremeTM laryngeal mask airway can meet clinical needs wonderful without significant difference in postoperative complications between the two kinds of laryngeal mask airway.
