Abstract：With the rapid development of social economy,modern medicine and medical equipment,the level of national health awareness is increasing.Coupled with the implementation of national screening programs for major diseases,there is a growing number of patients undergoing various endoscopic examinations and treatments,leading to an increasing demand for precise and comfortable medical care.Various painless endoscopic diagnosis and treatment have emerged accordingly.Gastrointestinal endoscopy,bronchoscopy,cystoscopy,hysteroscopy,and other endoscopic diagnoses and treatments are invasive procedures,which can easily cause strong discomfort to patients and may lead to complications such as hypoxemia and arrhythmia,affecting the quality of examination and patient safety.The use of surface anesthesia,local nebulized anesthesia,and local infiltration anesthesia by endoscopists has not achieved satisfactory results.It is recommended to provide moderate sedation and analgesia for patients to enhance their comfort,reduce the occurrence of complications,and achieve precise diagnosis and treatment.Common intravenous drugs used in endoscopic diagnosis and treatment include sedatives,analgesics,anticholinergics,vasoactive drugs,and antiemetic drugs,among which sedatives and analgesics can be used in combination.Formulating individualized anesthesia plans for different patients and different endoscopic diagnoses and treatments is a challenge faced by every anesthesiologist,who must ensure patients'safety and comfort while minimizing the impact of drugs on patients and achieving high patients'satisfaction.This review aims to summarize and evaluate related drugs used in painless endoscopic diagnosis and treatment,providing guidance for clinical practice.
