Role of pulseoximetry monitoring during gastrointestinal endoscopy with sedoanalgesic premedication
Recent guidelines recommend routine pulseoximetry monitoring during endoscopy, however this has not been the common practice yet in the majority of the local endoscopic units. Aims: to draw the attention to the importance of the routine use of pulseoximetry monitoring during endoscopy. Method: A prospective multicenter study was performed with the participation of 11 gastrointestinal endoscopic units. Data of pulseoximetry monitoring of 1249 endoscopic investigations were evaluated, out of them 1183 were carried out in sedation and 66 without sedation. Results: Oxigen desaturation was observed in 19,1% of the cases. It occurred most often during ERCP (31,2%) and proximal enteroscopy (20%). Procedure-related risk factors proved to be long duration of the investigation and premedication with pethidine or combined sedoanalgesia with pethidine and midazolam (34,38%). The age over 60, obesity, consumption of hypnotics or sedatives, severe cardiopulmonary state, or rather ASA score III and IV were found as patient-related risk factors. Conclusion: Increasing the safety of the patients undergoing endoscopic investigation pulse oximeter and oxigen supplementation should be the standard in all of the endoscopic investigation rooms. Pulseoximetry monitoring is advised routinely during endoscopy with special regard to the risk factors of hypoxemia.
