Ultrasound Guided Erectror Spinae Block Versus Intracavitary During Medical Thoracoscopy (ESPB)

May 7, 2026 updated by: Donia Hany Saad, Kafrelsheikh University

Ultrasound-Guided Erector Spinae Plane Block Versus Intracavitary Local Anaesthesia for Peri-procedural Analgesia During Medical Thoracoscopy: A Randomized Control Trial

The primary aim: is to compare the effect of US guided ESP block at two levels versus intracavitary blockade in medical thoracoscopy on total peri-procedural (intraoperative and post-operative 12 hours) nalbuphine consumption (mg) during medical thoracoscopy. Secondary aims: Time to first rescue analgesia, postoperative VAS, haemodynamics, recovery time (Aldert > 9), and adverse events

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

  • Phase 3

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • 100 patients belonging to American Society of Anesthesiologists (ASA) I-III scheduled for medical thoracoscopy under adequate sedation and analgesia.

Exclusion Criteria:

  • Patients will be excluded if; history of allergy or contraindication to any of the studied drugs, BMI more than 35 kg/m2 chronic opioid use or abuse, patients for whom ESPB block is contraindicated (patient refusal, coagulation disorder, skin infection at the injection site), history of post-thoracotomy, chest wall deformity, severe uncontrolled comorbidity, intubated patients, or if the interventional physician wants general anaesthesia from the start

Active Comparator: 50 patients will receive two levels of ultrasound-guided erector spinae plane block (ESPB) at T5 an
Procedure: ultrasound-guided erector spinae plane block in medical pleuroscopy
On the lateral decubitus position, under full aseptic technique; a high frequency (5-13 MHz) linear probe (or curvilinear in obese patients) of ultrasound covered sterilely will be placed in a parasagittal longitudinal orientation approximately 3 cm lateral to the spinous process to identify the trapezius, rhomboid major (if present), erector spinae muscle and thehyperechoic transverse process with its acoustic shadow, with the target being the fascial plane deep to the erector spinae muscle and superficial to the transverse process; the needle will be inserted in-plane in a cranial-to-caudal direction under real-time ultrasound guidance until it contacts the transverse process, after which 1-3 ml of normal saline is injected to confirm correct plane by lifting the erector spinae muscle off the transverse process, then following negative aspiration 20 ml of 0.25% bupivacaine at each level (10 ml 0.5% bupivacaine + 10 ml normal saline ) will be injected incrementally
Active Comparator: patients will receive intracavitary anaesthesia ICA with total volume 40 ml, 20 ml of 0.25% bu
Procedure: Intracavitary anaesthesia ICA
After skin infiltration with lidocaine 2%, at the entry point of the trocar, small (2-4 cm) skin incision in the chest wall will be done, A trocar will be introduced into the pleural cavity. If necessary, air is introduced to allow the lung to collapse, creating space to view the pleural surface. The thoracoscope will be inserted to visualize the pleura. The interventional pulmonologist will receive the pre-prepared syringe from the block anaesthetist and will administer the solution intracavitarily via the thoracoscope working channel, without knowledge of its contents. In both groups, a total volume of 40 mL of solution is administered: 20 mL is sprayed over the costal, diaphragmatic, and mediastinal pleura via the thoracoscope working channel, and an additional 20 mL is injected through the chest tube inserted at the end of the procedure , 10-mL normal saline flush, and the chest tube is then clamped for 5 minutes

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
