Paravertebral Block

This single-center, prospective, randomized controlled trial aims to compare the effects of paravertebral block (PVB), external oblique intercostal (EOI) block, and intravenous patient-controlled analgesia (PCA) with tramadol on postoperative pain and opioid consumption in patients undergoing elective laparoscopic cholecystectomy. The primary endpoint is total tramadol consumption within 24 hours postoperatively. Secondary outcomes include pain scores, additional analgesic use, incidence of nausea/vomiting, mobilization time, and length of hospital stay.

Chronic pain after Mastectomy is frequent and an important healthcare priority because of its effect on quality of life. Although the association between the severity of acute pain after surgery and the likelihood of chronic pain is known, their causal relationship has not been clarified. Mastectomy, frequently done for the management of breast cancer, is associated with significant acute postoperative pain and limited shoulder movement.

Video-assisted thoracoscopic lung resection (VATS) is a minimally invasive surgical approach frequently used in the treatment of lung cancers. The most commonly used analgesic technique for this surgery is the paravertebral block with a single peroperative injection of local anesthetic. However, a recent study conducted at our institution revealed that this approach provided less relief than expected in some patients. In light of these results, it becomes crucial to distinguish between technical failures (absence of sensitive anesthesia) and the intrinsic limits of the chosen regional analgesia technique (pain originating from an unanesthetized area or pain despite the presence of sensitive anesthesia) in order to better relieve patients. This study aims to objectively assess the areas of anesthesia obtained through three methods of paravertebral block to evaluate their respective performance and optimize post-VATS analgesic management.

The primary aim of this study was to compare the postoperative analgesic efficacy of thoracic paravertebral block with erector spinae plane block, which we use in thoracotomy surgeries. Secondary aims were to compare these groups in terms of Riker Agitation-Sedation Scale (RASS) scores, postoperative complications, postoperative opioid consumption, and patient satisfaction.

This study aims to compare paravertebral block and thoracic epidural in awake thoracotomy.

The study aims to evaluate the analgesic efficacy of paravertebral block, mobilization speed, respiratory functions, and complication rates in patients who have undergone cardiac surgery and are monitored in the intensive care unit during the postoperative period.

The goal of this clinical trial is to compare the analgesic efficacy of thoracal paravertebral block (TPVB) and serratus posterior superior intercostal plane block (SPSIPB) in patients undergoing video-assisted thoracoscopic surgery (VATS). The main questions it aims to answer are: How will the total perioperative opioid consumption of the patients receiving two different blocks change? How will TPVB and SPSIPB effect the patients' numeric rating scores for pain in the postoperative 24-hour period? How will TPVB and SPSIPB effect the incidence of opioid related side effects? Participants will be divided in two groups: TPVB group will receive a TPVB before the surgery. SPSIPB group will receive a SPSIPB nerve block before the surgery. Researchers will compare the results between the groups to see the postoperative effects concerning opioid consumption as well as the pain scores, respiratory parameters and opioid associated side effects. The hypothesis of this study is that participants receiving SPSIPB for VATS will have a less total opioid consumption 24 hours postoperatively.
