Abstract

BACKGROUND:

Laryngeal mask airway (LMA) is frequently used as a replacement method for endotracheal intubation. Few studies have investigated placement of laryngeal mask airway in pediatric surgical patients. In the present study, we aimed at comparing the success rate of 2 techniques, classic versus rotational, in the correct placement of laryngeal mask airway in pediatric patients.

METHODS:

After obtaining approval from the research committee of Faculty of Medicine, and receiving clearance from the ethics board of the University, this randomized controlled clinical trial (RCT) was administered on children of 2 months to 8 years with ASA class I & II undergoing lower abdominal surgical procedures in Motahari hospital in Urmia. General anesthesia using muscle relaxant was the preferred anesthesia technique for all the patients. Demographic data were recorded. Success rate, number of trials for correct placement, cuff leak pressure, and blood stain on the cuff of the laryngeal mask airway after its removal were all recorded.

RESULTS:

In the present study, 116 children were evaluated and placed into 2 groups. According to the results of the t test, no significant effect of age, weight, or average number of trials in mask placement was observed between the 2 groups (P > 0.05). According to the results of the Fisher's exact test, no significant difference was detected between the 2 groups in blood staining on the cuff (P > 0.05); no leak was recorded in any of the LMA placement methods (classic or rotational).

CONCLUSIONS:

Both insertion techniques work well in pediatric surgical patients. Success rate and complications were comparable between the 2 groups.
