Abstract
ObjectiveTo describe the anaesthesia/sedation complications during gastrointestinal endoscopy, as well as comparing scheduled procedures versus urgent procedures. MethodsA protocol was developed to define the anaesthesia/sedation in gastrointestinal endoscopy, where the anaesthetist should always be present. These include ASA 3 and 4 patients, complex tests such as polypectomies, endoscopic retrograde cholangiopancreatography (ERCP) or endoscopic ultrasound, deep sedation, or patients with probable difficult airway management. An analysis was made of the safety based on the complications recorded from the data directly collected automatically from the monitors, both during the sedation and in the recovery unit. An analysis was also performed on the risk factors associated with cardiorespiratory complications, the effectiveness based on the completed tests and the overall level of satisfaction through an interview using a satisfaction scale. ResultsThe study included a total of 3746 patients over a 7 year-period. The incidence of major complications was low, especially haemodynamic and respiratory complications. An incidence of hypoxaemia of 3% was found in scheduled endoscopy versus 5.7% in urgent endoscopy (P<.05). The rate of hypotension was also low, with significant differences between scheduled and urgent endoscopy (6.4% vs. 18.8%, P<.001). In present study, no test had to be suspended due to poor patient tolerance, and the satisfaction was high in more than 99% of cases. ConclusionThe participation of the anaesthetist in sedation for gastrointestinal endoscopy has shown excellent results in this study, in terms of safety and efficacy, mainly in the most serious patients and complex tests, as well as a high level of satisfaction.
