An interventional study of Chewing Gum in Laryngeal Mask, Throat Pain and Anxiety, sponsored by Ankara Medipol University. Enrolling by invitation at 2 sites in Turkey. Open to female participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2023-12-26.

Why
  1. The registry often attaches Pharyngitis to studies about something else, and this study's title and listed conditions do not name it.
  2. The study's listed conditions name Pain.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

This study was planned to investigate the effect of chewing gum in the preoperative period on patients' sore throat and anxiety levels.

Read the detailed description

Postoperative sore throat is a common complaint (1,2). It is reported in the literature that there are various pharmacological methods to reduce this condition, such as the use of nebula, corticosteroids, nonsteroidal anti-inflammatory drugs, or lidocaine. However, these methods have various advantages and disadvantages (3,4). Chewing gum, one of the non-pharmacological methods may be safer for the patient. Chewing gum increases salivary gland secretion and provides lubrication of the oral cavity (5). For this reason, it was thought that chewing gum before surgery could reduce throat pain after using a laryngeal mask due to the effect it provides. It has been determined that there are few experimental studies on the subject in the literature (6,7).

The presence of preoperative anxiety may lead to an increase in the need for intraoperative anesthesia and analgesic consumption in the postoperative period (8,9). However, it may cause a decrease in patient satisfaction and prolong the recovery process in the postoperative period (8,9). Pharmacological approaches can be applied to address this concern. However, non-pharmacological approaches may be safer for patients. Chewing gum during this process can also reduce patients' anxiety levels. A sufficient number of studies on the subject could not be found (10).

The study will conduct as a prospective randomized controlled trial. After obtaining verbal and written consent from the patients before and after the surgery, the study will conduct with various data collection forms.

These forms are; patient Identification form, Amsterdam Preoperative Anxiety and Information Scale (APAIS), Visual Analogue Scale (VAS). Patients will randomize. The chewing gum group in group- I (n=46), and group II (n=46) will be the control group. We have two stage.In first stage; anxiety levels will be measured for both group. In second stage; throat pain will evaluated at 2.-4.-6. hours.

Inclusion criteria

  • Undergoing elective surgery
  • Being intubated with a laryngeal mask
  • Being ASA () I-II

Exclusion criteria

Exclusion Criteria:

  • Using cigarette

    • Having asthma
    • Having chronic laryngitis
    • Having gastroesophageal reflux
    • use in the preoperative or intraoperative period
    • Mallampati score greater than two
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Study arms

  • Experimental
    Chewing Gum

    Before the surgery, the patient will chew gum for 2 minutes and routine nursing care will be applied. Anxiety level will be evaluated before and after chewing gum.

    Other: Chewing Gum

  • No intervention
    Control Group

    Anxiety level will be evaluated before and after routine nursing care.

Interventions

  • OtherChewing Gum

    The patient will be asked to chew gum before the surgery during the 2 minutes. Anxiety level will evaluated before and after chewing gum.

What researchers measure

Primary outcomes

  1. Change from preoperative anxiety level in a 2 minutes

    In this section, the anxiety level will decrease or disappear. This status will evaluate with Amsterdam Preoperative Anxiety and Information Scale (APAIS). APAIS consists of two scales, including a four-item anxiety scale and two-items information requirement. Items are rated on a Likert scale from 1 ("not at all worried") to 5 ("very worried"). The score ranges for the anxiety subscale and the information need subscale are 4-20 and 2-10, respectively. High scores are associated with higher levels of anxiety and need for information. Cronbach's α coefficients for the anxiety subscale and the information need subscale were 0.86 and 0.68, respectively (Moerman et al.1996). Çetinkaya et al. The validity and reliability of the Turkish translation of APAIS was verified in 2019. Cronbach's α coefficients of the APAIS anxiety and information need subscales were 0.897 and 0.786, respectively

    Time frame: After chewing gum for 2 minutes

Secondary outcomes

  1. Change from postoperative throat pain level at 2., 4., 6. hours

    In this section, the degree of postoperative throat pain level will decrease or disappear. This status will evaluate with Visual Analogue Scale (VAS). VAS is a horizontal line with a length of 10 cm. According to VAS, 0 is the lowest level and 10 is the highest level.

    Time frame: Time frame: Postoperative time at 2., 4., 6., hours
