Abstract
Objective. To determine whether pain associated with second trimester genetic amniocentesis is decreased by using subfreezing rather than room temperature needles.
Methods. Subjects were randomized to a - 14°C or room temperature (20-22°C) 22-gauge spinal needle. Patients, blinded to allocation, recorded anticipated and actual pain before and after the procedure, respectively, using a 0-10 visual analog scale with 0 = no pain and 10 = excruciating pain.
Results. Thirty-three subjects were randomized to room temperature and 29 subjects to subfreezing needles. Anticipated pain was similar in room temperature, 5.1 ± 1.7, and subfreezing groups, 4.9 ± 2.0, respectively (p = 0.6). ...
