... [8] Although the existing literature favors removal of LMA at a deeper plane of anesthesia, [4,7,8] the instruction manual of the LMA suggests that LMA may be removed in awake patients with intact upper airway reflexes. [9] Moreover, many clinicians prefer to remove LMA in awake patients to avoid airway obstruction. A Cochrane database systematic review that included 15 RCTs was unable to comment upon the superiority of the either technique. ...

Such large tidal volumes required inspiratory pressures up to 33 cm water that far exceeds the manufacturer's recommendation of 20 cm water. 12,14 Our study differed in several important respects from those of previous investigators. [8][9][10][11] They used LMA size #3 and size #4 respectively for women and men, whereas we used the larger sizes #4 and #5. ...

... The first of the SADs was the laryngeal mask airway (LMA), which was introduced into clinical use in 1988. 1 The success of LMA triggered the design of several new variations of the device. 2 Second generation SADs include the air-Q® laryngeal mask airway and the Ambu® Aura-i™. ...

... The supraglottis airway management like as the laryngeal mask airway (LMA) is used in order to increase the efficiency of gas exchange (7). The laryngeal mask airway (LMA) has many types such as classic LMA, ProSeal LMA, cobra LMA and other with different uses (8, 9, 10, 11 and 12).Many complications may be result from LMA insertion like as ProSeal LMA including laryngeal edema, airway obstruction, malposition (13,14,15,16), gastric distention, gastroesophageal reflux may be without aspiration (17,18,19). ...

... Así en 1981 el Dr. Brain en el London Hospital, describió el uso de la máscara laríngea (ML) para la cirugía dental ( 2 ), a partir de lo cual en 1983 se realizan una serie de correcciones y perfeccionamientos ( 3 ). Recién en 1988 es introducida en el mercado luego de múltiples ensayos clínicos controlados ( [3][4][5]8,9 ). En nuestro servicio se usa en forma permanente recién desde mayo de 1995 ( 6 ), constituyéndose en un elemento muy importante para el control y manejo de la vía aérea en pacientes ambulatorios, al ser mucho más eficaz que la máscara facial, y menos invasiva y más fácil de usar que el tubo endotraqueal. ...

... The reason is speculated that the placement of the laryngeal mask requires more physiological bending structures, and there is a certain pressure when inflating and sealing the laryngeal cavity. Due to individual differences in patients and inflating pressure, it is easy to cause mucosal damage [23]. In summary, general anesthesia under nasopharyngeal airway or laryngeal mask ventilation modes can meet the requirements of sedation and analgesia for this surgery, with comparable anesthesia effects, which is beneficial for patient hemodynamic stability and reducing stress reactions. ...

... I nsertion of laryngeal mask airway (LMA) is a non-invasive method in short-term procedures and difficult tracheal intubation [1,2]. LMA placement requires a sufficient depth of anesthesia, relaxation of the jaw muscles, and suppression of airway reflexes to tolerate it inside the hypopharynx [3]. ...
