Conductance catheter measurement and effect of different anesthetics in a rat model of postresuscitation myocardial dysfunction.

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
We demonstrate the usefulness of left ventricular pressure-volume (PV) loops generated by the use of conductance catheter measurements and investigate the influence of the type of general anesthesia on postresuscitation myocardial dysfunction in a rat model of cardiac arrest (CA) and subsequent cardiopulmonary resuscitation. A total of 42 Wistar-Han rats were randomized to receive general anesthesia with sevoflurane and resuscitation after CA, general anesthesia with pentobarbital intraperitoneally and resuscitation after CA, or general anesthesia with pentobarbital without CA (sham group). Myocardial function, assessed by analysis of PV loops, was measured continuously and in real-time by using a PV-conductance catheter. Rats were monitored for 3 h after restoration of spontaneous circulation (ROSC). The use of PV-conductance catheters supported objective and reliable evaluation of myocardial function and proved feasible in this rat model of CA. End-diastolic volume increased in rats anesthetized with pentobarbital after ROSC (before CA, 237 ± 45 μL; after ROSC, 402 ± 64 μL). Preloadadjusted maximal power before CA was the same in all groups but decreased in both resuscitated groups. The decrease was less pronounced in rats anesthetized with sevoflurane compared with pentobarbital (11.8 ± 4.9 mW/μL(2) compared with 4.8 ± 1.9 mW/μL(2) at 3 h after ROSC). This finding indicates that the type of general anesthesia influences postresuscitation myocardial dysfunction in this rat model of experimentally induced CA and cardiopulmonary resuscitation. Rats that were anesthetized with sevoflurane exhibited less postresuscitation myocardial dysfunction than did those anesthetized with pentobarbital.
