Abstract


Background: The obstetric airway is a signicant cause of maternal morbidity and mortality. A video laryngeal mask airway (VLMA) new
production. In this randomized controlled trial, we compared the Supreme LMA (SLMA) with OPLAC and VLMA in managing the obstetric
airway during cesarean section.
Methods: It was a randomized, single-blinded, study involving 60 pregnant women who underwent elective cesarean section under general
anesthesia were randomized in three groups a) SLMA b) OPLAC and c) Video LMA. The success rate, insertion time, beroptic view, peak airway
pressure, sealing pressure, incidence of gastric insufations, trace of blood on the device, and incidence of postoperative sore throat were
evaluated.
Results: The success rate of placement on the rst attempt was high for all the three devices. The insertion time was signicantly shorter and
engagement was better noted on beroptic view with the OPLAC and Video LMA than with the Supreme LMA. The sealing pressure was
signicantly higher and the incidence of gastric insufations was signicantly lower with the OPLAC and Video LMA than SLMA.
Conclusions: OPLAC and VLMA could be an alternative airway management technique for a carefully selected low-risk obstetric population,
with similar insertion success rates, reduced time to ventilation and less gastric insufations compared with SLMA.
