January 30, 2019 updated by: Celaleddin Soyalp, Yuzuncu Yıl University

Effect of Two Different Volumes of Bupivacaine 0.25% Used in Ultrasound-guided Erector Spinae Plane (ESP) Block on Dermatome Spread: A Volume Study

To investigate the effect of two different volumes of bupivacaine 0.25% used in ultrasound-guided erector spinae plane (ESP) block on dermatome spread and postoperative analgesia in patients undergoing unilateral thoracotomy

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.

Detailed Description

The study will have a double-blind design and will be conducted after obtaining an approval from the local ethics committee. The study will include 50 patients planned for thoracotomy, aged 18-65 years with an ASA score of I-II. The patients will be randomized by sealed tender and will be divided into 2 groups with 25 patients each. Patients that will be transferred to the intensive care unit (ICU) intubated after the surgery, patients with a body mass index of 35 or over, patients detected with infection in the intervention site, patients with hematological diseases, patients with a known allergy to local anesthetics, patients that will not provide a written or verbal consent, pregnant patients, and patients with an ASA score of III or IV will be excluded from the study. All the patients will undergo physical examination and their laboratory parameters will be evaluated one day prior to the procedure. Moreover, on the same day, each patient will be informed about dermatome testing (hot/cold), pain prick test (pain test), and pain pump set. Age, body height and weight, duration of block, and duration of surgery will be recorded for each patient

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.

Primary Completion (Anticipated)

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. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
