BACKGROUND: This study aimed to evaluate the applicability of Cobra perilaryngeal
airway (Cobra PLA?) for obese patients under general anesthesia and also to
compare the results with those of classic laryngeal mask airway (LMA?). MATERIALS
AND METHODS: Seventy-three overweight and obese patients were included in this
study. The patients were randomly assigned to LMA? or Cobra PLA? groups. Time
required for intubation, successful intubation attempt, airway sealing pressure
and incidence of complications including blood staining, sore throat and
dysphagia were assessed and noted. RESULTS: Thirty-six and 37 patients were
randomly allocated to LMA? and Cobra PLA? groups, respectively. Most patients
were males and had Mallampati Class II airway in both groups. The first attempt
and overall insertion success for Cobra PLA? was significantly higher compared to
LMA (P<0.05). Airway insertion was more successful (P = 0.027; 94% vs. 77%) with
Cobra PLA?. Insertion times were similar with Cobra PLA? and LMA? (Cobra PLA?,
29.94±16.35s; LMA?, 27.00±7.88s). The oropharyngeal leak pressure in the Cobra
PLA? group (24.80±0.90 H2O) was significantly higher than that in LMA? group
(19±1 H2O, p<0.001). Sore throat was more frequent in the LMA? group although it
did not reach statistical significance (Fisher's exact test, P = 0.33). Blood
staining on airway tube was seen in both groups with a higher incidence in the
Cobra PLA? group (Fisher's Exact test, P = 0.02). Incidence of dysphagia was not
different between the two groups. CONCLUSION: CobraPLA? was found to be safe with
low complications. It provided better airway sealing with high rate of the first
insertion success for use in obese and overweight patients. This study recommends
the use of CobraPLA? as a rescue device in emergency situations for obese and
overweight patients.
