Positive-pressure Ventilation with the Laryngeal Mask Airway in Children

Size 2 ProSeal™ laryngeal mask airway: a randomized, crossover investigation with the standard laryngeal mask airway in paediatric patients

“…Twenty-eight male and two female patients were included in the study; no patient had to be excluded from data analysis. The mean age, height and weight were 46 (18-81) months, 103 (75-120) cm and 16 (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21) All devices were placed at the first attempt. Ease of insertion and initial quality of airway was similar for both devices (Table 1).…”

“…Although first only used as a replacement for the face mask, it is now used in areas where the endotracheal tube was formerly used. [15][16][17][18][19] Although its safety and efficacy has been shown in several large studies there are limitations of its use in paediatric patients, in particular with the size 1 and 2 SLMA. [4][5][6] A principal concern is that its low-pressure seal might be inadequate for positive pressure ventilation so that there is a risk of gas leakage into the stomach with the subsequent risk of gastric distension and regurgitation.…”

Intraoperative pulmonary oedema in a child following systemic absorption of phenylephrine eyedrops

“…Airway integrity, gas leak and abdominal distension should be closely monitored. 6 In our case, gastric insuf¯ation would probably not have arisen had a tracheal tube been used. A tracheal tube would also have allowed us to ventilate at higher airway pressures during resuscitation, thereby potentially reducing the degree of pulmonary oedema (albeit at the risk of barotrauma).…”

LMA Extubation in Pediatric Patients: A Comparison of Inflated and Deflated LMA Cuff Methods

“…Use of LMA requires careful insertion and removal. It has been mentioned in many resources that the laryngeal mask should be removed if the patient is fully awake to prevent the possible complications that may occur (11,12). In other literatures, due to differences in physiology between adults and children such as children do not respond well to call, and the judge for the depth of anesthesia in children is difficult, its recommended to extubate LMA in anesthetic state in children (12)(13)(14).…”
