ay) laryngeal mask airway and PLMA (laryngeal mask airway ProSeal) laryngeal mask anesthesia in the short airway management in effect. Methods 60 patients, male or female, age 20 to 61 years old, weighing 47 ~ 78kg, ASA Ⅰ or Ⅱ short elective surgery under general anesthesia patients. Body mass index (BMI) <30, no contraindications LMA, were randomly divided into two groups: namely, SLIPA ventilation group (S group) and PLMA ventilation group (P group). Records were nausea, vomiting, cough, hoarseness, regurgitation and aspiration, laryngeal mask ventilation surface sticky blood, 24 hours of surgery and postoperative sore throat and other follow-up whether the incidence of adverse reactions. Ease of LMA insertion (easy: 15s in a one-time placement success; a little difficult: ≥ 15S success of a placement; difficulty: 2 times into a successful model placement or replacement; failed: 2 times after the implantation or replacement models without success.) and intraoperative ventilation situation. Results. Two LMA insertion success rates were similar. Airway inserted, S group 2 patients, P 6 patients need to be conducted to further adjust the position of intermittent positive pressure ventilation (internittent positive pressure ventilation, IPPV); patients in P group only 5 patients need to re-adjust to maintain IPPV, S group were successfully operated throughout the IPPV (P <0.05). The two groups after adjustment SpO2, PETCO2 were in the normal range, normal preoperative gastric tube placement, aspiration and regurgitation did not occur bloating situation. Compared with the P group, S group after laryngeal mask sore throat sticky blood and the incidence of surgery was statistically significant P <0.05). 24 hours after the incidence of sore throat was no significant (P> 0.05). Conclusion. SLIPA PLMA airway Airway and simple insertion, airway sealing, and can effectively guarantee ventilation, adverse reactions. SLIPA airway insertion operation easier, but also does not cover inflation, not because of hyperinflation, or diffusion of carbon monoxide and carbon dioxide pressure caused by increased cover to maintain IPPV is more stable than the PLMA. SLIPA laryngeal mask anesthesia for short surgical airway management of patients better.
