Confirmation of Epidural Catheter Location by Epidural Pressure Waveform Recordings by the Compuflo<sup>® </sup> Cath-Checker System

Abstract: Background: Pulsatile waveforms originating from the spinal cord and transmitted through the dura in synchrony with heart rate have been used to confirm the epidural location of the catheter. Lumbar epidural space identification using the CompuFlo ® instrument has been reported and validated. The aim of this preliminary study was to evaluate the new CompuFlo instrument which allows the identification of pulsatile waveform recordings. Methods: We tested 30 epidural catheters previously successfully used for pos… Show more

“…This result was similar to that previously obtained in a completely different setting, such as with epidural catheters previously used for post-cesarean analgesia and about to be removed. 6 Concerning laboring women, using a commercially available transducer for invasive pressure, Sebbag et al 7 observed no epidural pressure waveforms without priming, and they attributed their findings to anatomical and physiological differences in the lumbar epidural space of parturients. On the contrary, Al-Aamri et al 8 who used an invasive blood pressure transducer reported a pulsatile waveform in 96% of cases in laboring women, after priming the epidural space with 5 mL of saline, as suggested by de Medicis et al 9 However, unlike us, these previous studies in laboring women to date observed epidural waveforms through the epidural needle and not through the epidural catheter.…”
