About this study

Official title: Comparison of the Effects of Superior Hypogastric Plexus Block and Erector Spinae Plane Block on Postoperative Analgesia in Total Laparoscopic Hysterectomy Surgery

Total laparoscopic hysterectomy (TLH) is one of the most commonly performed gynecological surgeries today. Various analgesic techniques are used for the management of postoperative pain. The aim of this study is to compare the postoperative analgesic efficacy of superior hypogastric plexus block (SHPB) and erector spinae plane block (ESPB) in patients undergoing TLH procedures.

Read the detailed description

This prospective, randomized, double-blind, single-center clinical trial aims to compare the postoperative analgesic efficacy of Superior Hypogastric Plexus Block (SHPB) and Erector Spinae Plane Block (ESPB) in patients undergoing total laparoscopic hysterectomy (TLH).

Following ethics committee approval (2022/514/220/10), the study was conducted between March 2022 and March 2023. Patients aged 18 to 65 years, classified as ASA physical status I-II and scheduled for elective TLH, were enrolled. Participants were randomly assigned into three groups using computer-generated randomization (n=30 per group): SHPB, ESPB, and Control. Both the anesthesiologist performing postoperative evaluations and the patients were blinded to group allocation.

All patients received general anesthesia in accordance with a standardized protocol.

ESPB was performed bilaterally at the T10 level under ultrasound guidance. SHPB was performed laparoscopically at the L5-S1 level after uterine removal. No regional block was applied in the control group.

Postoperative pain management was provided to all patients via patient-controlled analgesia (PCA). Pain levels were evaluated using the Visual Analog Scale (VAS) at postoperative 0, 30, 60, 90, and 120 minutes, and at 6, 12, and 24 hours.

This study aims to investigate whether SHPB provides more effective visceral analgesia compared to ESPB and whether this leads to reduced opioid requirements and improved patient satisfaction following TLH.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Superior Hypogastric Plexus Block (SHPB)Procedure or surgery

    Laparoscopic superior hypogastric plexus block with bupivacaine and lidocaine injection near sacral promontory.

  • Erector Spinae Plane Block (ESPB)Procedure or surgery

    Erector spinae plane block with ultrasound-guided injection of bupivacaine and lidocaine at T10 level.

Study groups in NCT07078643
Study groupRoleWhat they receive
Superior Hypogastric Plexus Block (SHPB) GroupActive comparatorSHPB Group: In this group, patients received a superior hypogastric plexus block (SHPB) following total laparoscopic hysterectomy. After uterus removal and vaginal cuff closure, and before trocar removal, the injection site was identified laparoscopically. The block was performed in all patients by a single surgeon experienced in SHPB.
Receives: Procedure: Superior Hypogastric Plexus Block (SHPB)
Erector Spinae Plane Block GroupActive comparatorESPB Group: Patients in this group received erector spinae plane block (ESPB) during anesthesia maintenance after surgery. Patients were positioned in the lateral decubitus position. At the T10 level, the ultrasound probe was placed in the midline to identify spinous processes, then moved 2-3 cm laterally to visualize the transverse process, trapezius, and erector spinae muscles. The same procedure was performed on the opposite side. All blocks were performed by a single anesthesiologist experienced in ESPB.
Receives: Procedure: Erector Spinae Plane Block (ESPB)
Control GroupNo interventionControl Group: Patients in this group did not receive any block and were managed with standard postoperative care only. This group served as the comparison group to evaluate the effects of the block interventions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Total Tramadol Consumption

    The total amount of tramadol administered via a patient-controlled analgesia (PCA) device within the first 24 hours after total laparoscopic hysterectomy. This measurement is used to compare the postoperative analgesic efficacy of superior hypogastric plexus block (SHPB) and erector spinae plane block (ESPB) with the control group receiving no block. Tramadol consumption is recorded in milligrams (mg) and extracted directly from PCA device logs.

    Measured: Postoperative 0-24 hours

Secondary outcomes (3)
  1. Postoperative Pain Intensity (VAS Scores)

    Pain levels will be measured using the Visual Analog Scale (VAS), a 10 cm horizontal line labeled "no pain" at 0 cm and "worst imaginable pain" at 10 cm. Patients will indicate their pain intensity at postoperative time points (e.g., 1h, 6h, 12h, 24h). The score is determined by measuring the distance in centimeters from the "no pain" anchor to the patient's mark. Higher scores indicate greater pain intensity.

    Measured: Postoperative 0-24 hours

  2. Time to First Rescue Analgesia

    Duration from the end of surgery to the time the patient first requests additional analgesia beyond the standard postoperative regimen.

    Measured: Postoperative 0-24 hours

  3. Incidence of Postoperative Nausea and Vomiting (PONV)

    The proportion of patients experiencing nausea and/or vomiting within the first 24 hours after surgery.

    Measured: Postoperative 0-24 hours

Questions about this trial

What is this clinical trial studying?

A study testing Superior Hypogastric Plexus Block (SHPB) and Erector Spinae Plane Block (ESPB) in people with Total Laparoscopic Hysterectomy, run by Dr. Lutfi Kirdar Kartal Training and Research Hospital at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Total Tramadol Consumption (time frame: Postoperative 0-24 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jul 2025.
