Abstract

Background: The aim of this study was to assess the practicality of the ProSeal laryngeal mask (PS-LMA) airway during laparoscopic surgery with capnoperitoneum compared to endotracheal intubation (ET).

Methods: Prospective, randomized study. 104 patients undergoing gynaecologic, laparoscopic surgery were allocated randomly to two groups: 1. ET-group (n = 50). 2. PS-LMA-group (n = 54). Total intravenous anaesthesia was performed by the same anaesthesiologist.

Measurements: Mean arterial pressure, heart rate, at 4 and circuit pressure at 2 measurement points, and the incidences of coughing and sore throat. Insertion of the ET and the PS-LMA was scored by using a four-point scale. Ease of placing the gastric tube was judged by measuring the number of attempts at insertion and the insertion times. A p-value of < 0.05 was considered as significant.

Results: There were no differences between PS-LMA and ET concerning circuit pressure at any measurement point. At the end of anaesthesia, mean arterial pressure (92 +/- 13 vs. 100 +/- 14 mmHg; p < 0.01) and heart rate (66 +/- 13 vs. 76 +/- 14 beats/min; p < 0.01) were lower in the PS-LMA-group compared to the ET-group. At the end of anaesthesia 25 patients of the ET-group coughed but nobody in the PS-LMA-group (p < 0.00001). There was no difference with regard to postoperative sore throat. The insertion of the PS-LMA was easier compared to ET (p < 0.05), but we found no significant difference concerning insertion times. Fewer attempts at insertion of the gastric tube were necessary in the PS-LMA-group than in the ET-group (p < 0.01), whereas insertion times did not differ.

Conclusion: The PS-LMA is a convenient and practicable approach for anaesthesia in patients undergoing laparoscopic surgery.
