Background: Although sedation during gastrointestinal endoscopy is widely used in China, the characteristics of sedation use, including regional distribution, personnel composition, equipment used, and drug selection, remain unclear. The present study aimed to provide insights into the current practice and regional distribution of sedation for gastrointestinal endoscopy in China. Methods: A questionnaire consisting of 19 items was distributed to directors of anaesthesiology departments and anaesthesiologists in charge of endoscopic sedation units in mainland China through WeChat. Results: The results from 2758 participating hospitals (36.7% of the total) showed that 9 808 182 gastroscopies (69.3%) and 4 353 950 colonoscopies (30.7%), with a gastroscopy-to-colonoscopy ratio of 2.3, were conducted from January to December 2016. Sedation was used with 4 696 648 gastroscopies (47.9%) and 2 148 316 colonoscopies (49.3%), for a ratio of 2.2. The most commonly used sedative was propofol (61.0% for gastroscopies and 60.4% for colonoscopies). Haemoglobin oxygen saturation (SpO 2 ) was monitored in most patients (96.1%). Supplemental oxygen was routinely administered, but the availability of other equipment was variable (anaesthesia machine in 64.9%, physiological monitor in 84.4%, suction device in 72.3%, airway equipment in 75.5%, defibrillator in 32.7%, emergency kit in 57.0%, and difficult airway kit in 20.8% of centres responding). Conclusions: The sedation rate for gastrointestinal endoscopy is much lower in China than in the USA and in Europe. The most commonly used combination of sedatives was propofol plus an opioid (either fentanyl or sufentanil). Emergency support devices, such as difficult airway devices and defibrillators, were not usually available.

Purpose of review The present review provides an overview of the different fields of procedural sedation and analgesia (PSA), describing the evidence from recently published studies concerning anxiety and moderate pain, cardiac interventions, gastrointestinal interventions, and PSA use in infants. It also provides guidance for practitioners of both unscheduled and scheduled procedural sedation, and a summary of the current guideline for PSA. Recent findings Safety always has to be first priority. Recently published literature is focusing on the combination of different well established drugs such as dexmedetomidine, remifentanil, propofol, and ketamine. These traditional and well known drugs are commonly used for PSA. The combinational use of multiple drugs seems to have benefits for both the provider and patient. Furthermore, there is growing interest into specific protocols and adaption for special circumstances. The preferred medications used for PSA should be both effective and well tolerated. Summary Procedural sedation deserves to have high degree of attention for potential adverse events. New combinations of well established drugs provide a better pharmacokinetic profile, fit to different indications and offer multiple benefits for both provider and patient.
