Publication Metadata only A new technique at insertion of laryngeal mask airway(2013-06-04) Esen A.; Bakan M.; Topuz U.; Ertaş Dursun Z.; Karaaslan K.; ESEN, ASIM; KARAASLAN, KAZıMA new technique at insertion of laryngeal mask airway Esen A., Bakan M., Topuz U., Ertas Z., Karaaslan K. (Bezmialem Vakif University, Dept of Anaesthesiology & Intensive Care, Istanbul, Turkey) Background and Goal of Study: Laryngeal mask airway (LMA) have been frequently used for airway management. The satisfaction of the insertion and trauma at insertion are problems. We present a new in insertion technique for LMA with partially inflated cuff. Materials and Methods: Consecutive 157 patients undergoing general anesthesia with LMA were randomized to two groups by coin toss. Induction and maintenance of anesthesia were standart in two groups. There were 85 patients in study group (group S) and 72 patients in control group (group C). LMA insertions were made by same physician. LMA was inserted with standart technique -which was described by Brain- at group C. Laryngeal mask airway was inserted with new techinque at group S. In new technique the head was positioned with extension by nondominant hand, mouth was opened with dominant hand, LMA was held with dominant hand from the tube part and inserted until the tip touches to the oropharynx. The index finger of nondominant hand was inserted to mouth to pass by the LMA and reach the tip of it and the tip of LMA was directed to caudal by index finger. Then LMA was inserted by the guidance of the index finger towards it reaches to the trianguler base of the orophariynx. Results and Discussion: There were no difference between the groups for the demographic details, ASA scores, insertion success and duration of anesthesia. The mean age was 47 ,4 for group S and 51,7 for group C. Count of attempt was better in study group. Mean count number was 1,11 at group S and 1,28 at group C (p=0.02). Also blood on LMA were seen more common at group C (p=0.04). There were no statistical difference at sore throat but it was less seen at group S. Also airway satisfaction was not statistical different between groups but while all airways were succesfull in group S we can not inserted LMA by standart method at 1 patient and inserted it at first attempt by new technique. Conclusion: New technique is less traumatic and easy to use at daily practice. References: 1. Brain AIJ : The laryngeal mask. A new consept in airway management. Br J Anaesth 55:801,1983. 2.
