ABSTRACT
Background: Hemodynamic stability is an important aspect to the anesthesiologist for patients. Laryngoscopy and endotracheal intubation can cause striking changes in Hemodynamics as result of intense stimulation of sympathetic nervous system. ProSeal LMA (PLMA)minimizes this response without compromising the airway. The aim of this study was to compare PLMA and Endotracheal tube with respect to intra-operative hemodynamic responses in patients undergoing general anaesthesia. Material and Methods: This prospective observational study was conducted on 30 patients of either sex, age group of 18-60 years, ASA (I or II), Mallam Pati (I or II) posted for elective surgery under general anaesthesia. They were randomly divided into two group 15 each. For group A, airway was secured with laryngoscopy and intubation with appropriate size endotracheal tube and for group B, appropriate size PLMA was inserted to secure airway. The hemodynamic responses like Heart rate and Blood pressure were recorded at base line, at insertion, after 1st min, 3rd min, 5th min and after extubation. Mean increase was statistically more after endotra Results: cheal intubation than PLMA insertion. The elevation in these hemodynamic parameters significantly persisted for a longer period of time in the ETT group, where it returned to the baseline value by 5 minutes as compared to the PLMA group where it returned by 3 minutes. The hemodynamic res Conclusion: ponse produced when PLMA was used for securing airway was less than the laryngoscopy and endotracheal intubation. Thus, PLMA proved to be a suitable alternative to endotracheal tube for airway management with stable hemodynamic.
