Outcome Measures

Primary Outcomes (2)

  • Gender specific differences in sore throat 24 hours postoperative

    Comparing the incidence of postoperative sore throat between males and females within the first 24 hours after general anaesthesia with a second-generation Ambu® AuraGain™ Laryngeal Mask for elective, ophthalmological surgery

    24 hours after general anaesthesia (removal of laryngeal mask)

  • Differences in sore throat 24 hours postoperatively in correlation to cuff pressure

    Comparing the incidence of postoperative sore throat within the first 24 hours after general anaesthesia with a second-generation Ambu® AuraGain™ Laryngeal Mask for elective, ophthalmological surgery in correlation to cuff pressure (45 cmH2O and 60 cmH2O)

    24 hours after general anaesthesia (removal of laryngeal mask)

Secondary Outcomes (1)

  • Risk factors for postoperative sore throat in correlation to gender and cuff pressure

    From end of general anaesthesia (removal of laryngeal mask) until at minimum Day 3. If symptoms persist past Day 3 postoperatively, the maximum observation period is 100 days or until freedom of symptoms (whichever comes first)

Study Arms (4)

Women - low cuff pressure

OTHER

A cuff pressure of 45 cm H2O is used to block the laryngeal mask

Device: Ambu® AuraGain™ Laryngeal Mask (LM)

Men - low cuff pressure

OTHER

A cuff pressure of 45 cm H2O is used to block the laryngeal mask

Device: Ambu® AuraGain™ Laryngeal Mask (LM)

Women - normal cuff pressure

OTHER

A cuff pressure of 60 cm H2O is used to block the laryngeal mask

Device: Ambu® AuraGain™ Laryngeal Mask (LM)

Men - normal cuff pressure

OTHER

A cuff pressure of 60 cm H2O is used to block the laryngeal mask

Device: Ambu® AuraGain™ Laryngeal Mask (LM)

Interventions

Depending on the gender and randomization, the LM is either blocked with 45 cmH2O or with 60 cmH2O cuff pressure. Following general anaesthesia, patients are questioned for postop complications, with focus on postoperative sore throat and hoarseness.
