Transcutaneous carbon dioxide monitoring to avoid hypercapnia during complex catheter ablations: a feasibility study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe aim of this study was to determine if transcutaneous CO(2) monitoring (TCO(2)) is feasible to avoid hypercapnia during complex catheter ablation. Cumulative analgesic and anxiolytic effects during complex catheter ablation can rarely provoke hypoventilation and respiratory complications. End tidal CO(2) monitors have limitations in non-ventilated patients, and frequent arterial blood gas sampling is impractical.
methodsConsecutive patients undergoing catheter ablation for atrial fibrillation (AF) or ventricular tachycardia (VT) received continuous TCO(2) monitoring. Procedural evaluation of TCO(2) was performed concomitantly with point-of-care arterial blood gas testing. Endpoints included PCO(2) protocol feasibility, TCO(2)/PCO(2) agreement, and avoidance of hypercapnia-related procedural complications.
resultsFifty patients [AF n = 36 (72 %), VT n = 14 (28 %)] underwent catheter ablation (mean 221.7 ± 57.0 min duration, median 41.4 ± 21.1 min fluoroscopy) in which 6.0 ± 2.6 mg midazolam and 449 ± 225.5 mcg of fentanyl were administered. Monitoring protocol implementation was feasible in 50/50 (100 %) cases. Protocol-driven anesthesia consultation avoided an unplanned intubation in 1 case (2 %) and there was only 1 unplanned intubation (2 %) for oxygen desaturation due to heart failure without hypercapnia during a VT ablation (TCO(2)/PCO(2) agreement <5 mmHg). There were no respiratory or pulseless electrical arrests (0 %) in the study. TCO(2) and PCO(2) correlated well (baseline: r = 0.75, p < 0.001; 1 h:r= 0.72, p < 0.001; 2 h: r = 0.55, p = 0.003; 3 h: r = 0.79, p = 0.02). However, desired agreement was lower than expected [baseline: 33/50 (66 %) < 5 mmHg, 48/50 (96 %) <10 mmHg; 1 h: 29/45 (64 %) < 5 mmHg, 39/45 (87 %) < 10 mmHg; 2 h: 14/26 (54 %) < 5 mmHg, 22/26 (85 %) < 10 mmHg; 3 h: 7/11 (64 %) < 5 mmHg, 10/11 (91 %) < 10 mmHg; >3 h: 1/3 (33 %) < 5 mmHg, 2/3 (66 %) < 10 mmHg].
conclusionTranscutaneous CO2 monitoring is feasible during complex catheter ablation and correlates with invasively obtained data. However, further development is needed to achieve the desired level of agreement.
