Clinical application of laryngeal mask airway in combination with propofol and remifentanil total intravenous anesthesia in anorectal operation

Objective To observe the clinical application of laryngeal mask airway (LMA) in spontaneously breathing: propofol and remifentanil total intravenous anesthesia in anorectal operation. Methods Fifty-seven cases of patients with anorectal operation, ASAⅠ-Ⅱ, propofol and remifentanil intravenous anesthesia in induced after insertion of standard laryngeal mask. anesthesia was maintained with Micro pump infusion of propofol 4-6 mg/(kg·h), remifentanil 0.1-0.2 μg/(kg·min). Patients breathed spontaneously during the operation, the change of life signs and adverse events was record. Results All cases were successful insertion of a LMA. No obvious changes could be found with HR, MAP that LMA insertion after 1 min, 1 min after operation, pull out the LMA after 1min, haemodynamic parameters keep stable after LMA. 23% cases of SpO295%, 14% cases of HR60/min. Without intraoperative or postoperative complications occurred. Conclusion With propofol and remifentanil total intravenous anesthesia laryngeal mask airway during general anesthesia with spontaneous breathing has the advantages as follows: haemodynamic is stable. Postoperative anesthesia recovery fast, less complications, but the need to pay attention to effect of remifentanil on heart, lung function inhibition.
