AbstractPrior to the removal of spinal microcatheters from the market in 1992, these catheters were used extensively in the Obstetric Anesthesia Service at the Medical Center of Louisiana. We report on a prospective survey of the clinical application of single-injection versus continuous-catheter spinal anesthesia. Two hundred sixteen patients had single-injection anesthesia, and 218 had continuous-catheter anesthesia. No neurologic complications other than postdural puncture headache (PDPH) were encountered in either group. Five patients had PDPH after single-injection technique, and 8 patients had PDPH from continuous spinal anesthesia. Patients with diabetes were at higher risk for PDPH, and blacks were at lower risk (relative risks 4.35 and 0.31, respectively). Additionally, PDPH was associated with lower intraoperative urine output. No increased risk of complications was found after continuous spinal anesthesia with microcatheters.
