STUDY OBJECTIVE: To compare a multiport, firm-tipped, close-ended, epidural catheter (Portex catheter) with a uniport, open-ended, soft-tipped, wire-reinforced catheter (Arrow catheter) in obstetric patients.
STUDY DESIGN: Prospective data collection for intradepartmental quality assurance.
SETTING: Obstetric unit in a tertiary care maternity hospital.
PATIENTS: 2612 patients requesting labor analgesia.
INTERVENTIONS: The Arrow catheter was used in 1,352 women and the Portex catheter in 1,260 women.
MEASUREMENTS AND MAIN RESULTS: The incidence of unsatisfactory block were 3.3% and 4.4% with the Arrow and Portex catheters, respectively (p = 0.2). The catheter perforated the dura matter in 0.4% of cases with both catheters. The incidence of epidural venipuncture was 1.1% with the Arrow catheter and 5.7% with the Portex catheter (p = 0.0001). Paresthesias occurred in 6% of cases with the Arrow catheter and 11. 2 % of cases with the Portex catheter (p = 0.0001). Epidural catheter reinsertion was required in fewer patients in the Arrow group than in the Portex group (4.8% vs. 7.1%; p = 0.01).
CONCLUSIONS: In obstetric patients, the softer uniport Arrow catheter produces paresthesias and venipunctures less frequently than the firm multiport Portex catheter.
