Outcome Measures

Primary Outcomes (1)

  • the incidence of POST scores>3

    POST was evaluated by the Numerical Rating Scale(NRS),which ranges from 0 to 10 points,with 0 indicating completely painless,1\~3 indicating mild discomfort,4\~6 indicating moderate pain,and 7\~10 indicating severe pain .

    within 24 hours after surgery.

Secondary Outcomes (1)

  • the POST scores

    2 hours,6 hours and 24 hours after surgery.

Other Outcomes (1)

  • subgroup analysis with patient subdivided based on whether the laryngeal mask had blood on it.

    Immediately after removal of laryngeal mask

Study Arms (2)

the Mouthwash group

ACTIVE COMPARATOR

Patients in the mouthwash group received 15 ml of honeysuckle antibacterial mouthwash and vomited it out after 2 minutes

Other: Mouthwash

the gum group

ACTIVE COMPARATOR

patients in group gum chewed one piece of herbal sugar-free gum for 2 minutes and then spat it out.

Other: chewed mint gum
