ABSTRACT

ABSTRACT

BACKGROUND AND OBJECTIVES: Laryngoscopy and endotracheal intubation (ETT) is the commonest method of securing a definitive airway but, is associated with significant hemodynamic stress response. Use of Laryngeal Mask Airway (LMA) in place of ETT is shown to have less hemodynamic response as it avoids laryngoscopy and penetration of larynx, thus less stimulating the sympathetic response. The study was carried out to compare the haemodynamics, insertion characteristics and complications where airway was secured by ETT and PLMA in elective surgical procedures requiring General Anesthesia. METHODS: A prospective, randomized study in 100 female patients, aged 20-40 yrs of ASA I and II posted for elective surgery under GA. Patients randomized to two groups. Group A – ETT (7 or 7.5 mm ID) and Group B - PLMA (size 3 or 3.5) was inserted. RESULTS: The increase in the HR from baseline was more during ETT intubation than PLMA insertion (94.24 ± 13.47 Vs 88.72 ± 10.27). (P<0.05)  Increase in MAP from baseline was more during ETT intubation than PLMA insertion (98.06 ± 7.51 Vs 93.88 ± 4.42). (P<0.05)  The duration of device insertion was comparable in two groups. (20.02 ± 2.45 Vs 20.60 ± 2.35 sec).  Postoperatively, sore throat and coughing was noted in two and four cases and minor trauma in one and two cases of ETT and PLMA respectively (P>0.05). CONCLUSION: PLMA insertion evokes significantly less hemodynamic stress response than ETT with comparable safety profile.
