Comparison of Different Cuff Pressure Use with the Supreme Laryngeal Mask Airway on Haemodynamic Response, Seal Pressure and Postoperative Adverse Events: A Prospective Randomized Study (original) (raw)

2018, Turkish journal of anaesthesiology and reanimation

The Supreme™ laryngeal mask airway (SLMA) is a supra glottic airway (SGA) device that is used as an alternative to endotracheal tubes. In the present study, we aimed to compare the use of the SLMA with normal cuff pressure and low cuff pressure, primarily for haemodynamic response. In the present study, 120 patients diagnosed with hypertension and scheduled for varicose vein or inguinal hernia operation were enrolled and 99 patients finished. Using randomization, patients were divided into two groups according to cuff pressure as a low-pressure group (Group L, 45 cm HO) and a normal-pressure group (Group N, 60 cm HO). Demographics, Mallampati score and the type and duration of surgery, heart rate (HR), mean arterial pressure (MAP), percentage of tidal volume leakage, Ppeak, Pmean, etCO, seal pressure, fibreoptic scores and postoperative adverse effects of all patients were recorded. MAP and HR values immediately and 2 minutes after SLMA insertion were significantly lower in Group L ...
