Postoperative Pain
Pulsed Electromagnetic Fields for Postsurgical Pain Management in Women Undergoing Cesarean Section: A Randomized, Double-Blind, Placebo-controlled Trial Results: Postoperative pain VAS scores were significantly lower in
the active-PEMF group in all the measured periods within the early
and the late postoperative periods. Fewer women in the active-
PEMF group experienced severe postoperative pain within 24
hours postoperatively (36% vs. 72%, P=0.002). Analgesic use
during the first 24 hours after C-section was 1.9-times lower in the
active-PEMF group (1.6±0.7 vs. 3.1±1.2, P<0.001). The total
analgesic use during the seventh postoperative days was 2.1-times
lower in the active-PEMF group than in the sham group (1.7±0.7
vs. 3.7±1.1, P<0.001). Seven days postoperatively, patients in
the active-PEMF group had better wound healing with no exudate,
erythema, or edema (P=0.02).
