Abstract :

 Background :  Proseal Laryngeal mask airway (ProSealâ„¢ LMA) is an advanced supraglottic airway device which has an additional port for gastric suctioning. We conducted a Comparative study of two techniques of insertion of ProSealâ„¢ LMA in children. Digital technique of insertion comparedwith Bougie Guided Technique of insertion.

Method  Eighty children (ASA I–II, aged 1–16 yr) were randomly allocated for ProSealâ„¢ LMA insertion using the digital or bougie–guided technique. The digital technique was performed according to the manufacturer‘s instructions. The bougie–guided technique involved priming the drain tube with a bougie, placing the bougie in the oesophagus under direct vision and railroading the ProSealâ„¢ LMA into position. Data were collected about the ease of insertion (number of attempts and time taken to provide an effective airway), ease of gastric tube placement, haemodynamic responses, blood staining and post operative airway morbidity.

Results : In bougie guided insertion technique changes in heart rate was more ( 12 vs 5 ,  P<0.0001), changes in blood pressure was more ( 11 mg vs 6 mmHg P<0.0001) and effective airway time was longer ( 48vs 32 s , P<0.0001) . There were no differences between groupsregarding success rate of insertion, ease of gastric tube placement,bloodstaining,and postoperative airway morbidity.

CONCLUSION:To conclude, the digital technique of  ProSealâ„¢ LMA insertion has similar characteristics compared with the bougie guided insertion in children, but the digital technique has more stable hemodynamics compared with the bougie guided technique. The effective airway time is more in bougie guided technique compared with digital technique.The success rate of LMA insertion, success rate of gastric tube placement, incidence of trauma and postoperative airway morbidity are similar in both digital technique group and bougie guided group.
