title: [Experimental study of the effects of transesophageal oxygen saturation monitoring on the safety of esophageal mucosa].
abstract: The present paper was aimed to study the security of burning during the continuous monitoring of transesophageal arterial oxygen saturation. 20 rabbits were randomly divided into two groups: control group and high-frequency electrotome group. All rabbits were implanted with the oxygen saturation detection probes into the lower esophageal after anesthesia. The probes were made up with two light-emitting diode (LED) and then connected with oxygen saturation sensor to monitoring for 2h and 6h, respectively. We then intercepted two luminous points as esophageal specimens and dist the esophageal tissue detection device headend 1cm gastric side esophageal specimens (self-contr01) after monitoring, and carried out pathological examination. The pathological results of the LED-1, LED-2 esophageal biopsy and self-control section were mucous integrity, submucosal mildedema, hyperemia, a small number of lymphocytes and mononuclear cell infiltration. All the score of the esophageal tissue histologic was 2. The results showed that montioring the SteO2 not more than 6h was safe with montiored using a matching of oxygen saturation sensor and monitoring esophageal arterial oxygen saturation.
