A Comparison Between the PLA Cobra™ and the Laryngeal Mask Airway Unique™ During Spontaneous Ventilation: A Randomized Prospective Study

Cobra perilaryngeal airway for thyroid surgery in a hypertensive patient

“…The fi beroptic view of the vocal cords is better with the CobraPLA than with the LMA-Classic [5,8]. In our patient also, the vocal cords were easily visualized on fi beroptic bronchoscopy via the CobraPLA.…”

“…The use of a supraglottic airway device was the other option available to us, as these devices prevent the stress response of laryngoscopy and intubation. Higher oropharyngeal sealing pressures have been reported with the CobraPLA compared with the LMA-Classic during controlled ventilation [4,5]. But a concern for securing the airway with a tracheal tube in case of diffi culty in ventilation during the course of surgery in our patient was present.…”

Brief review: The Cobra Perilaryngeal Airway (CobraPLA®) and the Streamlined Liner of Pharyngeal Airway (SLIPA™) supraglottic airways

“…While insertion times were similar with the three devices, first time insertion success rates with the CobraPLA® were lower, as compared with the Laryngeal Tube LT and the Intubating LMA™. 18 Gaitini et al 19 compared the CobraPLA® and the LMA Unique™ in 80 healthy adults undergoing minor surgeries. Insertion times for the CobraPLA® were longer than for the LMA Unique™.…”

“…Three of the studies show that airway sealing pressures are higher for the CobraPLA® than for the PAX™, the LMA Unique™, and the LMA Classic™. 19,21,22 Case reports and case series evaluating the CobraPLA® Hemodynamic and respiratory variables were reported to remain stable during insertion of the CobraPLA®, in two preliminary studies and cohort studies involving 34 cases. [23][24][25] The success of the CobraPLA®, in achieving effective ventilation, was reported in two cases of the LMA Classic™ failure in patients with head and neck burns, contractures, limited neck extension, and limited mouth opening.…”

A randomised, crossover comparison between the CobraPLA® and the LMA Classic™ in paralysed patients*

“…One of these devices, the CobraPLA Ò (Engineered Medical Systems, Inc., Indianapolis, IN, USA) is a relatively new supraglottic airway device that has been proven safe and effective in several clinical settings [1][2][3][4][5][6][7]. However, to the best of our knowledge, there is only one study that compares the performance of the CobraPLA with that of other supraglottic airways in paralysed patients and it did not examine the airway leak pressure.…”
