Paracervical Versus Intracervical Lidocaine for Suction Curettage: A Randomized Controlled Trial
In Brief
A clinical study evaluating Paracervical block, Intracervical, and 1 other intervention for Abortion, Induced and Pain. Completed, enrolled 89 participants across 1 site.
Detailed Summary
The aim of this study is to estimate the efficacy of intracervical versus paracervical block on pain experienced during first trimester suction curettage without the use of preoperative cervical ripening. Because of the theoretical improved reliability of stromal block, the investigators hypothesize that intracervical block would produce lower pain scores than paracervical block at the time of cervical dilation.
Study Details
Timeline
Interventions
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.
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.
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.
