To the Editor:
We report a case of epidural blood patch in a Jehovahs Witness (JW) parturient by using a continuous circuit technique.1
A young healthy primigravida was scheduled for an elective Cesarean delivery under epidural anesthesia. Accidental dural puncture occurred and the catheter was inserted into the subarachnoid space. 12.5 mg of 0.5% bupivacaine and 25 µg of fentanyl were injected and the Cesarean section was completed uneventfully under a spinal anesthetic.
The subarachnoid catheter was left in place and was removed on postoperative day (POD)1. Subsequently she developed a postural, occipital headache consistent with post-dural puncture headache. Initially, hydration, analgesics and iv caffeine were tried, but failed to achieve relief. The possibility of a blood patch was discussed on POD 2, but the patient refused this treatment option and opted for epidural saline. On POD 3, the patients headache was severe and prevented discharge from the hospital. She accepted the blood patch with the condition that the blood used remain in a continuous circuit. Utilizing this principle, a continuous circuit was established (Figure
). After placement of an 18-gauge Tuohy needle in the L2L3 epidural space, a four-way stopcock was connected to the needle along with a 20-mL syringe. Using an aseptic technique, an 18 -gauge iv catheter was placed in the left antecubital fossa and connected to a sterile iv extension tubing. Subsequently a 36-inch pressure tubing with male luer locks on both ends was connected to the iv extension tubing. The other end was connected to the four-way stopcock completing the circuit. Twenty millilitres of blood were aspirated and injected into the epidural space, providing complete relief within two hours. The patient was discharged home on POD 4 and remained free of complications.
