Abstract:

Objective To evaluate clinical effects of laryngeal mask airway (LMA) on impacted tooth extraction in the anterior maxillary region of children. Methods A total of 116 children were randomly divided into laryngeal mask group (L group, n=58) and endotracheal intubation group (T group, n=58). Blood pressure and heart rates were recorded before induction of anesthesia(T0), before laryngeal mask/tracheal intubation(T1), and after laryngeal mask/endotracheal intubation inserting(T2). We also recorded the time of extubation, the incidence of coughing and agitation during extubation and the incidence of sore throat and fever after surgery. Results At T2, systolic pressure(SP)、diastolic pressure(DP)and heart rate(HR)increased significantly in the T group (P<0.05). In L group, SP, HR at T2 increased significantly compared to T1 (P<0.05), but no significant difference was shown for DP (P>0.05). In T group, SP, DP, HR were all increased at T2 compared to T1 in L group (P<0.05). The blood pressure and heart rate of T2 in T group increased significantly compared with T1; at the same time, it also increased significantly compared with T2 in L group(P<0.05). The extubation time, the incidence of coughing and agitation during extubation in L group was significantly reduced compared with those in T group(P<0.05). Also, the incidence of postoperative sore throat decreased significantly compared with the T group(P<0.05). Conclusion Using LMA in the extraction of impacted teeth in the maxillary anterior region of children, is more conducive to maintaining hemodynamic stability during anesthesia and can significantly reduce the occurrence of adverse reactions during extubation and after surgery in children.
