Comparison of Midpoint Transverse Process to Pleura Block and Thoracic Paravertebral Block
Comparison of Midpoint Transverse Process to Pleura Block and Thoracic Paravertebral Block for Postoperative Analgesia in Video-Assisted Thoracoscopic Surgery (VATS)"

Detailed Description
Patients between the ages of 18 to 80, scheduled for Video-Assisted Thoracoscopic Surgery (VATS) and classified under the American Society of Anesthesiologists (ASA) class I and II, will be included in the study. Patients with known or suspected local anesthetic allergies, coagulopathy, site injection infections, a history of thoracic surgery, severe neurological or psychiatric disorders, severe cardiovascular diseases, liver failure, kidney failure (glomerular filtration rate <15 ml/min/1.73 m2), and chronic opioid use will be excluded from the study.
Demographic information of the patients (name, protocol number, weight, height, age, body mass index, comorbidities, ASA score) will be recorded. Subsequently, after necessary information is provided, and written and verbal consent is obtained, patients will be randomized into three groups:
Group MTPB: After the induction of general anesthesia and intubation in the operating room, the patient will be placed in the lateral decubitus position. Using ultrasound guidance, a linear probe will be used to perform a MTPB at the midpoint of the superior costotransverse ligament at the level of the 5th intercostal space. A 0.5 ml/kg solution of 0.25% bupivacaine will be administered in-plane.
Group PVB: After the induction of general anesthesia and intubation in the operating room, the patient will be placed in the lateral decubitus position. Using ultrasound guidance, a linear probe will be used to perform a paravertebral block (PVB) at the level of the 5th intercostal space. A 0.5 ml/kg solution of 0.25% bupivacaine will be administered in-plane.
Group P: No peripheral block will be performed in this group.
All patients' hemodynamic data (mean arterial pressure, heart rate, oxygen saturation) will be recorded at 30-minute intervals during the intraoperative period, as well as the amount of opioids used during the surgery. Fifteen minutes before awakening, an intravenous patient-controlled analgesia (PCA) device will be connected, delivering a bolus dose of 2 ml of 1 mg/ml morphine solution with a lockout time of 15 minutes.
During the postoperative period, visual analog pain scores (VAS) will be assessed at 0, 30 minutes, 1, 2, 4, 8, 12, 24, 36, and 48 hours, both at rest and during coughing. Additionally, the time to first analgesic requirement, total analgesic consumption, need for rescue analgesia (contramal 100 mg/2 ml), amount required, possible opioid side effects (nausea, vomiting, respiratory depression, sedation), and time to awakening will be recorded.
The time to first mobilization, postoperative complications, time to discharge, and satisfaction of both patients and the surgical team will be recorded using a 5-point Likert scale.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Placebo Comparator: Control group
group receiving general anesthesia only
|
Only general anesthesia was applied to the patients.
|
Active Comparator: paravertebral block group
received single-shot paravertebral block after induction of anesthesia.
|
Paravertebral block was applied to the patients after induction of general anesthesia; Intraoperative opioid requirement and postoperative pain scores and analgesic requirement were evaluated.
|
Active Comparator: mid transverse process block group
received a mid-transverse process -to- pleura block after induction of anesthesia.
|
Mid point transverse process block was applied to the patients after induction of general anesthesia; Intraoperative opioid requirement and postoperative pain scores and analgesic requirement were evaluated.

What is the study measuring?
Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Intraoperative analgesic effects of peripheral blocks
Time Frame: First day
|
Investigators will compare the intraoperative analgesic effects by opioid consumption in intraoperative phase.
|
First day
|
Postoperative analgesic effects of peripheral blocks
Time Frame: First day
|
Visual Analogue Scale (VAS) will be used for postoperative analgesic effects.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
opioid consumed through PCA (patient controlled analgesia)
Time Frame: first day
|
PCA was used for pain control.
An iv solution was prepared to all participants with 100 mg morphine hydrochloride at a concentration of 1 mg/ml in 90 ml saline and the bolus dose was set as 2 ml and the locked time as 15 min.
From the recovery unit, a bolus dose of morphine was administered with the PCA device if VAS≥4 by questioning or upon the request of the participants.
Participants who had VAS≥4 despite PCA were administered 50 mg dexketoprofen iv as rescue analgesic and 50 mg tramadol intramuscularly as the second rescue analgesic if VAS≥4 continued.

Side effects
Time Frame: First day
|
The necessity for supplementary analgesics, any complications associated with the puncture procedure such as infection, hematoma, and pneumothorax (confirmed via direct thoracoscopic visualization), the incidence of postoperative nausea and vomiting.
