Background: A variety of sedatives like ketamine, propofol, opioids, and benzodiazepines are used during Fibroptic bronchoscopy. The effectiveness of ketamine-dexmedetomidine and ketamine-midazolam on pain level and sedation after Fibroptic bronchoscopy was examined.
Methods: A double-blind, randomized clinical trial was carried out from October 2020 to April 2021 at educational hospitals affiliated with Isfahan University of Medical Sciences. The participants were 60 candidates for fibroptic bronchoscopy who were allocated randomly into two groups of 30 people. Group one (Ketodex) received 1mg/kg ketamine and 1 µg/kg dexmedetomidine for 10 min followed by an infusion of 0.5 µg/kg of dexmedetomidine and 0.5mg/min ketamine. Group two (Ketomed) received 2.5mg of midazolam and 1mg/kg of ketamine for 10min along with infusion of 1 µg/kg/min midazolam and 0.5mg/min of ketamine. The variables under the study were systolic blood pressure (SBP), mean arterial pressure (MAP), diastolic blood pressure (DBP), percentage of arterial oxygen saturation (SpO2), heart rate (HR), and level of pain. Furthermore, the sedation score of patients were recorded on the basis
of sedation score is a 5-point scale from 1 to 5. The obtained data were analyzed in SPSS (v.26). To compare the data collected at different occasions and different groups, repeated measure tests and independent t-test were used (P<0.05).

Results: Compared to the Ketomed group, the sedation term in patients in the Ketodex group was longer significantly (P<0.001) with a significantly shorter recovery term (P<0.001). In addition, the differences between the groups were insignificant in terms of diastolic blood pressure, systolic blood pressure, mean arterial pressure, heart rate, and percentage of arterial oxygen saturation (P>0.05). The pain levels were notably lower in patients who received Ketomed compared to Ketomed during 20 min (P=0.04) and 30 min (P=0.001) following the procedure.
Conclusion: The use of Ketodex was associated with a longer sedation duration and significantly shorter stay in the recovery room and lower pain intensity compared to Ketomed, therefore it may be more preferable in bronchoscopy. |
