| Abstract | Background Gastrointestinal endoscopy with sedation is frequently complicated by hypoxemia. Nasal cannulas have limitations in eliminating hypoxemia. We hypothesized that the combination of nasal clips and nasal cannulas would improve the inspired oxygen concentrations and prevent hypoxemia compared with the use of nasal cannulas alone. Methods A total of 600 adult patients were randomly assigned to receive supplemental oxygen through single-lumen nasal cannulas or through the combination of nasal clips and nasal cannulas. The primary outcome was the incidence of hypoxemia. Additionally, subclinical respiratory depression and severe hypoxemia, duration of hypoxemia, lowest SpO2 level, measures to increase oxygen saturation level, and adverse events such as cough and hiccups were compared as secondary outcomes. Results Three hundred patients in the nasal clip group and 296 patients in the nasal cannula group were included in the intention-to-treat analysis. Nasal clips significantly decreased the incidence of hypoxemia from 25.0–17.7%(RR = 0.707, 95% CI = 0.516 to 0.967, P = 0.029). The median and interquartile range of lowest SpO2 in the nasal clip group (96 [92 to 98]) was significantly greater than that in the nasal cannula group (95 [89 to 97]; median difference = 1.000, 95% CI = 0.000 to 2.000, P = 0.004). No significant differences were found between the two groups in subclinical respiratory depression or severe hypoxemia, duration of hypoxemia, adverse events or measures taken to increase oxygen saturation. Conclusions The combination of nasal clips and cannulas reduces hypoxemia during gastrointestinal endoscopy with sedation, demonstrating a significant advantage over the sole use of nasal cannulas, with tolerable adverse events.

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
