Superior Hypogastric Plexus Block Clinical Trial
Official title:
Intraoperative Superior Hypogastric Plexus Block For Pain Relief During Cesarean-Section: A Prospective Case-Control Study
PURPOSE: to evaluate the efficacy of superior hypogastric plexus block for pain relief after cesarean section
Superior hypogastric plexus block(SHPB) for pain relief is routinely implemented in cesarean
section operations at H.S.U Kocaeli Derince Education and Research Hospital. The
implementation of this procedure depends on the clinical situation of the patient, the
preference of the surgeon and the anesthesiologist, the course of the operation, and whether
the patient wishes or not. Superior hypogastric plexus block is performed with 0.25 %
bupivacaine 30 ml injected under peritoneum above promontorium.
This is a prospective case-control study. The sample consisted of 60 women having
cesarean-section with general anesthesia at H.S.U Kocaeli Derince Education and Research
Hospital divided into two groups: the first group having superior hypogastric plexus block
for pain relief and the control group not having superior hypogastric plexus block. All
participants signed an informed consent and the study was approved by the Ethics Committee of
Kocaeli University ( KUGOKAEK 2017/270). The sample size was calculated with G Power 3.1
program. With ki-square Goodness-of-fit test α:0.05 ,power 95% ,effect size 0.5 total sample
size was calculated 52, including 26 in case group and 26 in control group. Women having
cesarean-section with spinal anesthesia, women with known bupivacaine allergy, women with
anxiety-depression disorder, women with known fibromyalgia were not enrolled to the study.
Age, BMI(body mass index), education status, VAS (visual analog scale) scores ,the amount of
analgesic used and the hour of gas extraction and bowel movement will be recorded.
