Purpose: Gagging may be a challenge in daily otorhinolaryngology (ORL) routine. This cross-sectional study aimed to examine conditions of gagging as limitation to ORL examination and the efficacy of acupressure as tool to reduce exaggerated gagging.
Methods: The study was conducted on a total of 360 study subjects. There was a survey part and a routine ORL examination with observation of gagging behaviour. Through binomial univariate logistic regression, predictors of clinically relevant exaggerated gagging were identified. Wilcoxon signed rank test was used to evaluate efficacy of acupressure point CV-24 to reduce gagging while examination.
Results: First gagging's relevance was indicated by over 40% of study subjects showing clinically relevant exaggerated gagging. Furthermore, we found that more psychogenic than somatogenic features proved to be predictors of exaggerated gagging. Third acupressure point CV-24 showed statistical significant reduction of gagging intensity and improved examination feasibility.
Conclusion: Awareness of exaggerated gagging's predictors are the first step to deal with gagging in daily practice. Acupressure might be an effective tool to overcome gagging in the affected patients.
Level of evidence: We suggest at least Level IV according to Oxford (UK) CEBM Levels of Evidence.
