- Abstract: Objective To explore the optimal body position of patients during rigid laryngoscopy.Methods 120 outpatients who underwent rigid laryngoscopy from December 2023 to March 2024 were divided into the conventional body position group(58 cases)and the anterior tilted position group(62 cases)by the random number table method.Patients in the conventional body position group were examined in the conventional body position(upright lower head position)and patients in the anterior tilted position group were examined in the anterior tilted position(body tilted forward by 60° and jaw lifted).The vocal folds were scored on the Friedman scale,the visual analogue scale(VAS)score was used to evaluate the comfortable degree of patients during the examination,the incidence of gag reflex sensitivity and the rate of complete pharyngeal exposure were compared between the two groups of patients.Results In the conventional body position group,there were 26 cases of Friedman's difficult exposure and 32 cases of easy exposure.The VAS scores of difficult exposure and easy exposure patients were 2.5(1.0,5.8)and 1.0(1.0,3.0),respectively;The incidence of gag reflex sensitivity was 42.3%and 34.4%,respectively;and the rates of complete pharyngeal exposure were 76.9%and 100.0%,respectively.In the anterior tilted position group,there were 28 cases of Friedman difficult exposure and 34 cases of easy exposure.The VAS scores of patients with difficult and easy exposure were 1.5(1.0,7.0)and 2.0(1.0,4.0),respectively;The incidence of gag reflex sensitivity was 46.4%and 29.4%,respectively;And the rates of complete pharyngeal exposure were 82.1%and 91.2%,respectively;The differences were not statistically significant(P>0.05).Conclusion When rigid laryngoscopy is performed in the upright lower head position or anteriorly tilted position,there is no significant difference in the comfortable degree scores,incidence of gag reflex sensitivity,and the rate of complete pharyngeal exposure in the patients in the two positions,and the examiners can choose the appropriate position according to their own examination habits.
