Comparative Study of “Haemodynamic Changes between Endotracheal Intubations and LMA Insertion”

Abstract

To compare the haemodynamic changes between LMA insertion & endotracheal intubation, 60 patients were assigned randomly to one of the two groups of thirty each. They were grouped randomly by card sampling. Every patient included in the study was allowed a card preoperatively. According to the card number patients were grouped.

Group A. Airway was maintained by LMA.
Group B: Airway was maintained by ETT.

Haemodynamic parameter i.e. pulse rate, systolic blood pressure, diastolic blood pressure and presence of any dysrhythmia were monitored after 1,3,5 & 10 minutes after LMA insertion or ETT intubations. There was statistically significant changes (P<0.05) in pulse rate, systolic blood pressure, diastolic blood pressure and (appearance of dysrhythmia in some patients) in group ti patients whereas there was less changes in pulse rate, systolic blood pressure, diastolic blood pressure whose airway was maintained by LMA insertion (Group-A).

We conclude that LMA insertion causes less Haemodynamic changes than that of endotracheal intubation. So LMA insertion is safer than ETT intubations in some selected patients.
