Methods. 50 consecutive AF patients referred to our centre for transcatheter ablation, underwent hypnotic communication for periprocedural analgesia (Group A). A matched group of 50 patients undergone conventional analgesia approach was selected as control (Group B). Patients signed written informed consent for video recordings and reproduction. Procedural data, anxiety, perceived pain, perceived procedural duration and administered analgesic drugs dosages were compared using validated score scales.
Results. Hypnotic communication resulted in a significant procedural-related anxiety reduction (5.1±2.8 Vs 0.9±1.0, P<0,001) and perceived procedural duration (103±37 min Vs 78±41 min, P<0,001). Group A patient reported a painless procedure in 78.2% (Pain scale = 2). As regard analgesic drug Group A used only Fentanest and Paracetamol. Fentanest dosage did not differ between Group A and B (0.143 Vs 0.147 mg, P NS). Group A reported higher Paracetamol dosage (843 Vs 347 mg, P<0,001). Group B used also Midazolam (2.2 mg), Propofol (43.8 mg) and narcosis and intubation was required in 2 patients. Total radiofrequency (RF) delivered time did not differ between Group A-B (27.2 Vs 26.9 min, P NS) as well as mean RF power (35.6 Vs 35.8 W). No periprocedural complication occurred in both groups.
Conclusion. Hypnotic communication during AF ablation was related with significantly reduced procedural analgesic drugs dosage, perceived pain, perceived procedural duration and anxiety without affecting total radiofrequency delivered time and procedural safety.
