| Abstract | ||||
| The present study was performed to compare safety , efficacy of Proseal Laryngeal Mask Airway (PLMA), classic Laryngeal mask airway (LMA) and cuffed Endo Tracheal Tube (ETT) as a ventilatory device during controlled positive pressure ventilation and airway management , Haemodynamic response to insertion and removal, gastric tube insertion through either device, air leak detection and assessment of position by fiberoptic bronchoscope . Forty five ASA I or II patients aged between 18-55 years old , were divided equally into three groups of fifteen patients each , and airway management either through PLMA(groupI),classic LMA (groupII)and ETT (group III) . All patients were premedicated by zantac hydrochloride 150 mg orally at mid night and two hours before the operation – Anaesthesia was induced with fentanyl 2 ug/kg and propofol 2.5 mg /kg and maintenance was with a mixture of 50% N2O , 50% O2 and isoflurane 1 - 1.5 % and rocuronium 0.5 mg /kg followed by continous infusion of rocuronium 0.3-0.6 mg/kg/hr A proper size PLMA , classic LMA or ETT was selected oxygenation and ventilation were optimal in 100% in group I and III while in group II 80% optimal and suboptimal in 13.3% and failed in 6.7 % . Haemodynamic parameters showed that significantly increase in HR and MAP in the three studied groups especially at insertion and removal of the airway device with statisticaly significant difference between group I,II in comparison to group III, comparison of gastric tube insertion showed that positive insertion was 86.7% in group I and in 46.7% in group II, while in group III positive insertion was 100% air leak was detected by epigastric auscultation which signified lower leakage in PLMA group than LMA group . Position assessment by fiberoptic bronchoscope in PLMA group was grade 4 in 5 patients , grade 3 in 5 patients , grade2 in 4 patients and grade 1 in 1 patient while in LMA group it was grade 4 in 7 patients , grade 3 in 6 patients , grade 2 in 2 patients and grade 1 in no patient In conclusion :- PLMA and classic LMA could be better choices as ventilatory device in hypertensive and coronary artery disease patients . | ||||
