| Abstract | Background Painless gastrointestinal endoscopy is widely used for the diagnosis and treatment of digestive diseases. At present, propofol is commonly used to perform painless gastrointestinal endoscopy, but the high dose of propofol often leads to a higher incidence of cardiovascular and respiratory complications. Studies have shown that the application of propofol combined with ketamine in painless gastrointestinal endoscopy is beneficial to reduce the dosage of propofol and the incidence of related complications. Esketamine is dextrorotatory structure of ketamine with a twice as great anesthetic effect as normal ketamine but fewer side effects. We hypothesized that esketamine may reduce the consumption of propofol and to investigate the safety of coadministration during gastrointestinal endoscopy. Methods A total of 260 patients undergoing painless gastrointestinal endoscopy (gastroscope and colonoscopy) were randomly divided into P group (propofol + saline), PK1 group (propofol + esketamine 0.05 mg/kg), PK2 group (propofol + esketamine 0.1 mg/kg), and PK3 group (propofol + esketamine 0.2 mg/kg). Anesthesia was achieved by 1.5 mg/kg propofol with different doses of esketamine. Propofol consumption per minute was recorded. Hemodynamic index, pulse oxygen saturation, operative time, induction time, awakening status, orientation recovery time, adverse events, and Mini-Mental State Examination (MMSE) were also recorded during gastrointestinal endoscopy. Results Propofol consumption per minute was 11.78, 10.56, 10.14, and 9.57 (mg/min) in groups P, PK1, PK2, and PK3, respectively; compared with group P, groups PK2 and PK3 showed a decrease of 13.92% (P = 0.021) and 18.76% (P = 0.000), respectively. In all four groups, systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), but not pulse oxygen saturation (SpO2) significantly decreased (P = 0.000) immediately after administration of induction, but there were no significant differences between the groups. The induction time of groups P, PK1, PK2, and PK3 was 68.52 ± 18.394, 64.83 ± 13.543, 62.23 ± 15.197, and 61.35 ± 14.470 s, respectively (P = 0.041). Adverse events and psychotomimetic effects were observed but without significant differences between the groups. Conclusions The combination of 0.2 mg/kg esketamine and propofol was effective and safe in painless gastrointestinal endoscopy as evidenced by less propofol consumption per minute, shorter induction time, and lower incidence of cough and body movement relative to propofol alone. The lack of significant differences in hemodynamic results, anesthesia-related indices, adverse events, and MMSE results showed the safety to apply this combination for painless gastrointestinal endoscopy.

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
