Background: Supraglottic airway devices are currently available.
We compared the efficacy of the Cobra perilaryngeal airway
(CobraPLATM) and the ProSealTM laryngeal mask airway (PLMA)
during anesthesia with controlled ventilation for the insertion success
rate, hemodynamic stability after insertion, intraoperative ventilatory
parameters, and postoperative laryngeal discomfort.
Methods: Forty-three patients received either a CobraPLATM or a
PLMA after induction with thiopental 5 mg/kg, fentanyl 1μg/kg and
rocuronium 0.6 mg/kg, and manual controlled ventilation with N2O：
O2 (1：1) and sevoflurane 5 6 vol% for 2 minutes. Unblinded
observers collected the intraoperative data, and blinded observers
collected the postoperative data.
Results: The two devices were similar for hemodynamic stability
after insertion, and for the intraoperative ventilatory parameters.
The success rates of first-attempts were similar, but the insertion
time was longer for the CobraPLATM. The cuff volume and pressure
changes were significantly higher for the PLMA than the
CobraPLATM. The cuff pressure was significantly higher for the
CobraPLATM than the PLMA from insertion to 10 minutes after
insertion, but at 30, 60 and 90 minutes after the insertion, there
was no significant difference for the two devices. There were no
differences with respect to the incidence of adverse events.
Conclusions: During anesthesia with controlled ventilation, these
two devices can be used successfully and effectively. We suggest
that the CobraPLATM could be used an alternative device for airway
management and further investigation is required.
