Evaluation of Adding Dexmedetomidine to Ropivacaine in Pediatric Caudal Epidural Block: A Randomized, Double-blinded Clinical Trial
Abstract
Background Caudal block is one of the methods of pain management performed following lower abdominal surgery, though having its own limitations. Objectives In the present study, the effects and side effects of adding dexmedetomidine to ropivacaine in the caudal epidural block were investigated in children after lower abdominal surgery. Methods In this randomized, double-blinded clinical trial, 46 children aged three to six years were divided into two groups to perform a caudal block following lower abdominal surgery under general anesthesia. The injectable solution contained ropivacaine in the R group (1 mL/kg ropivacaine 0.2%), as the control group, and dexmedetomidine (2 µg/kg) and ropivacaine 0.2% (1 mL/kg) in the DR group. The pain score (modified CHEOPS score), duration of analgesia, amount of analgesia consumed (i.v. paracetamol), hemodynamic changes, and possible adverse effects were assessed at one, two, and six hours in both groups. Results The pain score at one and two hours showed no significant difference between the two study groups (P > 0.05). In the DR group, however, the pain score at the sixth hour was significantly lower, and the duration of analgesia was longer (P = 0.001). The amount of analgesic consumption was also lower in the DR group (P = 0.001). However, there was no significant difference in systolic blood pressure and heart rate (P < 0.05), in the case of diastolic blood pressure, a significant difference (P < 0.05) was seen (DR group lower than…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 46 participants or records.
