Analysis on factors affecting recovery time of older patients undergoing gastroscopy under sedation / 中华老年医学杂志

ABSTRACT

Objective:To investigate the factors affecting recovery time of older patients undergoing gastroscopy under sedation.Methods:A total of 266 older patients undergoing gastroscopy under sedation from August 2021 to September 2021 in Beijing Hospital were studied.Patients' basic information, combined disease, sedation depth, the operation time, sedation and analgesic drug dosage, Self-rating Anxiety scale(SAS)score, incidence of hypoxemia, vasoactive drug dosage and the total recovery time were recorded.The relationship between each variable and the total recovery time was studied by univariate linear regression analysis.The relevant factors of single-factor analysis result(all P<0.05)were analyzed by multilinear regression analysis to understand the influencing factors of the total recovery time. Results:The results of univariate linear regression analysis showed that the total recovery time after sedation was correlated with sex, depth of sedation, concomitant respiratory disease and SAS score( P<0.05).The results of multiple linear regression analysis showed a correlation of the total recovery time with depth of sedation( B=3.494, 95% CI 1.255-5.734, P=0.003), concomitant respiratory disease( B=5.925, 95% CI 1.563-10.286, P=0.008)and SAS score( B=0.322, 95% CI 0.114-0.530, P=0.002), but not with sex.Patients with deep sedation and concomitant respiratory disease had an extended overall recovery time, and the total recovery time was positively correlated with SAS score. Conclusions:Deep sedation, concomitant respiratory disease, and higher SAS score prolong the recovery time of older patients undergoing gastroscopy under sedation.
