Key result
Cryoballoon ablation for AF is linked to lower fentanyl and midazolam doses versus radiofrequency ablation.
Why the study?
It was unknown whether the demand for analgesic and sedative medication differs according to the type of catheter ablation for AF.
Does the type of catheter ablation for atrial fibrillation affect the demand for analgesic and sedative medication?
Observational (n=869)
No
Does the type of catheter ablation for atrial fibrillation affect the demand for analgesic and sedative medication?
Cryoballoon ablation was associated with lower sedation needs; hypothesis-generating and requires randomized confirmation before practice change.
Background: Our aim was to determine if there is a difference in demand for analgesic and sedative medication according to the type of catheter ablation for atrial fibrillation (AF). Material and methods: We collected data from protocols of 1144pts, who underwent ablation of AF. We excluded 275pts, at most due to electrocardioversion during the procedure. We divided them into 4 groups: cryoballoon ablation group (CB, n = 101), single-point radiofrequency ablation group (RFth-, n = 541), single-point radiofrequency ablation group with thermocool catheter (RFth+, n = 156) and Multielectrode Pulmonary Vein Ablation Catheter group (PVAC, n = 71). We used fentanyl and midazolam for pain control. The dose was adjusted by the operator, accord-ing to patients' request.

Koźluk et al. (2021) conducted an observational in Atrial fibrillation (n=869). Cryoballoon ablation vs. Radiofrequency ablation (single-point, thermocool, or multielectrode) was evaluated on Median dose of fentanyl (mg) (p=<0.001). Cryoballoon ablation for atrial fibrillation significantly reduced the median required dose of fentanyl (0.04 mg) and midazolam (1.00 mg) compared to radiofrequency ablation techniques (p < 0.001).
