Measure
Paracervical Block
Paracervical block: The paracervical block was administered using 20 ml of buffered lidocaine and a 5/8 inch, 25-gauge needle. A small amount was injected at the tenaculum site, and the remainder equally distributed around the cervicovaginal junction at 3, 5, 7, and 9 o'clock. The depth was standardized at 5/8 inch by inserting the needle to the hub. Buffered Lidocaine, vasopressin, sodium bicarbonate: The buffered lidocaine preparation for both block techniques consisted of 50 mL of 1% lidocaine, 5 units of vasopressin, and 5 mL 8% sodium bicarbonate.
Intracervical Block
Intracervical: The intracervical block was administered using 20 ml of buffered lidocaine and a 1-1/2 inch, 20 gauge needle in order to overcome the increased resistance to injection caused by the cervical stroma. A small amount was injected at the tenaculum site, and the remainder into the cervical stroma at 12, 3, 6, and 9 o'clock, at a depth of 1-1/2 inch by inserting the needle to the hub. Buffered Lidocaine, vasopressin, sodium bicarbonate: The buffered lidocaine preparation for both block techniques consisted of 50 mL of 1% lidocaine, 5 units of vasopressin, and 5 mL 8% sodium bicarbonate.
