The LMA ProSeal Laryngeal Mask is a re-usable second generation, gastric access device which forms an effective First Seal with the oropharynx (oropharyngeal seal) and an innovative Second Seal with the upper oesophageal sphincter (oesophageal seal)
This laryngeal mask enables the regurgitated fluid to pass up the drainage tube without leaking into the glottis
These laryngeal masks are latex free and reduces the likelihood of throat irritation and stimulation, and reduces post-operative nausea and vomiting by as much as 40% compared to an ETT
The mask achieves a high seal pressure, with a median seal pressure of 32 cm H2O
This laryngeal mask from Teleflex also features a built-in drain tube that allows expelled gastric content to bypass the pharynx. This specific feature is designed to decrease the risk of aspiration
LMA ProSeal includes all the benefits associated with an LMA airway: ◦ Fewer drugs ◦ Fewer sore throats in adults ◦ Reduced coughing and bucking ◦ Improved haemodynamic stability
The mask is available in 7 sizes: ◦ 1, Neonates/Infants (5 kg), 8FR ◦ 1.5, Infants (5-10 kg), 10FR ◦ 2, Infants/Child (10-20 kg), 10FR ◦ 2.5, Child (20-30 kg), 14FR ◦ 3, Child (30-50 kg), 16FR ◦ 4, Medium Adults (50-70 kg), 16FR ◦ 5, Large Adults (70-100 kg), 18FR
Supraglottic airway devices (SADs) are devices that keep the upper airway clear for unobstructed ventilation. Laryngeal masks are a type of supraglottic airway which keep a patient’s airway open during the state of unconsciousness and when the patient is under anesthesia. When the laryngeal mask is correctly placed, it sits above the glottis in the hypopharynx region.
Supraglottic Airway Devices (SADs) comprise a vast group of tools designed to provide a means for ventilation, oxygenation and administration of anaesthetic gases during situations of respiratory arrest or in a patient who is submitted to a surgical procedure under general anaesthesia.The laryngeal mask airway (LMA) is an acceptable alternative to mask anesthesia in the operating room. It is often used for short procedures when endotracheal intubation is not necessary.
How to insert a Laryngeal Mask Airway: ◦ First, Deflate The Cuff Properly ◦ Lubricate the Posterior LMA Surface ◦ Slight Flexion of the Head on the Neck Can Help ◦ How You Hold the LMA Matters ◦ Open The Mouth As Wide As You Can ◦ Insert As Far Back as Possible Until It Seats ◦ Be careful With the Tongue
