Abstract
This study was carried out after approval of ethical committee, in Sohag university hospital, fifty pediatric patients aged 3 months-10years with ASA grade I-II scheduled to undergoing congenital glaucoma surgery under general anaesthesia were enrolled in the study after obtaining informed written consent from patient’s parents.
This study aimed to compare both endotracheal (ET) tube and laryngeal mask airway (LMA) as a conduit for continuous ventilation during general anaesthesia as regard their effect on the hemodynamic responses and intraocular pressure (IOP) after their insertion in pediatric patients undergoing congenital glaucoma corrective surgery.
Patients were divided into two groups of 25 patients each. (group I) patients who were subjected to LMA insertion (group II )patients who were subjected to conventional laryngoscopy and endotracheal intubation.
The result of our study demonstrated that there was high significant differences between LMA insertion and endotracheal intubation as regard hemodynamic responses; Heart rate increased after insertion of ETT in (group II), HR at the base line was (125.72±8.31) and became (141.52±9.798) after tube insertion when compared with LMA in (group I), HR at the base line was (128.36±10.44) and became (132.00±10.336) after LMA insertion, (p value <0.05) and continued until 2 min after insertion. Also, there was a significant difference in the mean blood pressure after insertion in ETT group, BP at the base line was (55.32±5.113) and became (76.36±5.353) when compared with LMA group, BP at the base line was (55.28±5.192) and became (65.48±6.049) , (p value <0.05), BP continued to be elevated until 3 min after insertion.
As regard IOP in our study, we noted that there was no difference between two group at base line but there was a significant increase in the intraocular pressure after insertion in ETT group when compared with LMA group (p value<0.05), and continued until 3 min after insertion then regressing without significant difference between both groups all over the procedure, after removal of both devices ,there was increase in IOP measurement in both groups but the increase was insignificantly different between both groups (p value >0.05) .
As regard complications, in our study fewer complications occurred after removal of both devices ; as coughing in two cases (8%) in LMA group compared with six cases (28%) in ETT group, two cases (2%) had straining in LMA group compared with seven cases (28%) in ETT group ,one case (4%) had laryngospasm in ETT group with no significant difference between the two groups (p. value>0.05), also we noticed that complications as airways trauma, aspiration and gas leakage didn’t occur.

Laryngeal Mask Airway was better than endotracheal intubation when used as a conduit for airway management; it had less hemodynamic responses and changes in the IOP.
