Role of LMA \u2013 Proseal in anesthesia for laparoscopic surgery

ABSTRACT

Background: Is Laryngeal Mask Airway (LMA) Proseal superior over Endo Tracheal Tube (ETT) in anesthesia for laparoscopic surgery? Objective: (1) To evaluate the effect of LMA Proseal on blood pressure, heart rate and respiration in laparoscopic surgery. (2) To evaluate the surgical condition and side effects of LMA Proseal. Subject and Method: A single blind control study was done for 60 patients at Viet Duc Hospital. Patients were divided into 2 groups LMA Proseal group (30 patients) and control group (30 patients). Blood pressure, heart rate, SpO2, PetCO2, Pmax and Vh were monitored after laparoscopic surgery. Results: Compared with ETT, LMA Proseal attenuates the increase in blood pressure and heart rate; SpO2, PetCO2, Pmax and Vh are stable within safe limits like ETT. Conclusions: LMA Proseal provides stability for blood pressure, heart rate and respiration while facilitating surgical conditions and reducing postoperative side effects.
