A Randomized Comparison of LMA (Laryngeal Mask Airway) Supreme and LMA Proseal in Infants Below 10kg

A Randomized Comparison of LMA Supreme and LMA Proseal in Infants Below 10kg

The investigators conduct this study to evaluate the clinical efficacy of size 1 and 1.5 supreme LMA compared to proseal LMA for infants weighing <10kg.

This is a randomized prospective study to compare the clinical efficacy and safety for size 1 and 1.5 LMA supreme and LMA Proseal. The airway leak pressure of these 2 devices will be compared and other parameters such as time to insertion, insertion success rate, fibreoptic glottic view and intraoperative complications will be recorded.

Inclusion Criteria:

• Weight of < 10kg
• ASA (American Society of Anesthesiologists) I-II
• Infants undergoing elective surgery under general anaesthesia using supraglottic airway device.
• Informed consent obtained from parents.

Exclusion Criteria:

• ASA III-IV and emergency surgery
• Neonates and ex-premature babies with post conceptual age <55 weeks.
• Infants with history of difficult airway.
• Infants with features of difficult intubation.
• Active upper respiratory tract infection
• Infants with pulmonary disease
• Infants with history of gastroesophageal reflux disease
• Infants with risks of regurgitation and aspiration.
