Abstract
OBJECTIVES: Different sedo-analgesia and monitoring methods are used during endoscopic procedures. And yet, there is no consensus on optimal sedating agents. In this study, the main aim is to compare ketamine-propofol and remifentanil propofol sedo-analgesia protocols by monitoring integrated pulmonary index (IPI). METHODS: The study population is divided into two groups: Group ketamine received 0.25 mg/kg ketamine and 0.75 mg/kg propofol at the beginning of anesthesia. 1 mcg/kg of remifentanil and 0.75 mg/kg propofol were administered to group remifentanil patients at the induction of anesthesia. Anesthesia maintenance was provided by titration of drug doses according to the Ramsey sedation scale. Measurements were taken at four different points in time: just before anesthesia was induced, five minutes after sedation was induced, ten minutes later, and five minutes after the treatment was finished. RESULTS: There was no significant difference in respiratory parameters such as respiratory rate, SPO2, and EtCO(2) measured in the T1 time period between the groups. In the T2 time period, a significant difference was found between the groups in the integrated pulmonary index (IPI), sPO2, respiratory rate, and systolic pressure parameters were found to be significantly higher in group ketamine. T3 time period results were higher in these three parameters: IPI, sPO2, and respiration rate. In the T2, T3, T4 time periods, there was a difference between the groups in the respiration count parameter and it was found to be higher in group ketamine. CONCLUSION: Although it causes slight prolongation in recovery, ketamine is a safe and effective drug that can be used during endoscopic procedures.
