RESUMO

PURPOSE: To evaluate the applicability and airway management capacity of v-gel(r) and Cobra PLA in rabbit anaesthesia during assisted (AV) or controlled ventilation (CV). METHODS: This study was carried out in 44 adult New Zealand white rabbit. Baseline arterial pH, PaCO2 and PaO2 values were recorded. Anaesthesia was induced with 5 mg/kg xylasine and 35 mg/kg ketamine HCI combination. AV rabbits were assigned as; control (CG-AV; n=5), LMA (LMA-AV; n=5), cobra PLA (PLA-AV; n=5) and v-gel (v-gelAV; n=5). Rabbits have CV were also assigned as; ET (ET-CV; n=6), LMA (LMA-CV; n=6), cobraPLA (PLA-CV; n=6) and v-gel (v-gelCV; n=6). All measurements were repeated 1st, 5th, 15th and 30th mins during anaesthesia. RESULTS: The less insertion time, number of attempt and complications are recorded in v-gel applied rabbits compared to other apparatus. For arterial pH values significant differences are recorded in especially at 15th and 30th min between groups of CV (p<0.005 or p<0.001). All groups had similar results with each other during anaesthesia for PaCO2 except for LMA-CV group. CONCLUSION: The v-gel may be used as airway device in rabbit anaesthesia undergoing AV or CV and also can be a suitable alternative to endotracheal tubes and laryngeal mask airway. .

RESUMO

BACKGROUND: The Cobra Perilaryngeal Airway (CobraPLA) and the Laryngeal Mask Airway (LMA) Classic are supraglottic airway devices. We compared the performance of the CobraPLA and the LMA Classic devices during volume-controlled ventilation in children. METHODS: Eighty children, ASA physical status I-II, aged 1-10 years were randomly assigned with either the CobraPLA or the LMA Classic for airway management. Anesthesia was induced with 1 mg/kg ketamine and 2.0 mg/kg propofol, and muscle relaxation was obtained with the use of 0.5 mg/kg rocuronium. All patients were mechanically ventilated with a tidal volume of 10 m/kg in 1-3% sevoflurane, oxygen and air. The number of insertions, oropharyngeal leak pressure, and fiberoptic airway position were measured. Measurements of blood pressure, heart rate, oxygen saturation, end-tidal carbon dioxide, and peak inspiratory pressure were recorded every 5 minutes. Postoperative adverse events were assessed. RESULTS: There was no significant difference between the use of the two devices with respect to the number of insertions, time of insertion, and fiberoptic score. The oropharyngeal leak pressure was significantly higher for the CobraPLA than the LMA Classic (25.4 +/- 4.9 cmH2O versus 20.3 +/- 5.4 cmH2O; P < 0.001). Hemodynamic and respiratory variables were similar with the use of both devices. The incidence of adverse events was not different with the use of both devices. CONCLUSIONS: Both airway devices provided an adequate airway and effective ventilation during volume-controlled ventilation in children. The CobraPLA had a higher sealing pressure than the LMA Classic.
