Thoracic Paravertebral Block for Postoperative Pain Management in Percutaneous Nephrolithotomy Patients: A Randomized Controlled Clinical Trial
نویسندگان
چکیده
OBJECTIVE To investigate the effect of thoracic paravertebral block (PVB) on pain control and morphine consumption in percutaneous nephrolithotomy operations. SUBJECTS AND METHODS This randomized controlled clinical study was performed on 60 American Society of Anesthesiologists (ASA) I-II patients between the ages of 18 and 60 years who underwent percutaneous nephrolithotomy with approval of the ethical committee and written consent of the patients. Patients were randomly allocated into two groups: group P had 4 ml of 0.5% levobupivacaine injected at each of the T10, T11, and T12 paravertebral spaces and a standard PVB, and group C received 4 ml of 0.9% NaCl solution. All patients were given standard general anesthesia. The follow-up of saturation, heart rate, peripheral oxygen, and blood pressure values was recorded before induction, intraoperatively, and postoperatively. At postoperative 1, 2, 6, 12, and 24 h, the visual analog scale (VAS), Ramsey sedation score, respiratory rate, and 24-hour total morphine consumption were recorded. In addition, side effects and satisfaction of patients were recorded. RESULTS VAS scores and total morphine consumption were lower in group P than in group C: 2.3 vs. 4.3 and 22.3 vs. 43.2 mg, respectively (p < 0.05). The level of satisfaction was higher in group P than group C. Differences between groups in other parameters were not significant. CONCLUSIONS Thoracic PVB with levobupivacaine provided a good postoperative analgesia and increased patient satisfaction for those who underwent percutaneous nephrolithotomy.

Paravertebral block for surgical anesthesia of percutaneous nephrolithotomy
BACKGROUND Paravertebral block is often used to provide postoperative analgesia after renal surgery. In this case-series report, we present our experience with 3 patients in whom percutaneous nephrolithotomy was performed successfully under ultrasound-guided 3-segment lumbar-thoracic paravertebral block. CASE SUMMARY Three patients were scheduled for percutaneous nephrolithotomy. All 3 patien...

BACKGROUND Thoracic paravertebral block (TPVB) is a regional block technique increasingly used for the early management of post-thoracotomy pain. We compare three different postoperative analgesic approaches based on TPVB: anesthetist, anesthetist plus surgeon, and surgeon. MATERIALS AND METHODS We randomized 54 patients undergoing elective thoracotomy to three different postoperative analges...

BACKGROUND Percutaneous nephrolithotomy (PCNL) is a minimally invasive surgical procedure for renal calculi, and nephrostomy tubes lead to postoperative pain after PCNL. Regional techniques (e.g., epidural analgesia and peripheral blocks) and opioids are applied for postoperative pain treatment. The aim of this study was to compare effectiveness of ultrasound-guided paravertebral block (PVB) an...

Comparison of continuous epidural block and continuous paravertebral block in postoperative analgaesia after video-assisted thoracoscopic surgery lobectomy: a randomised, non-inferiority trial.
BACKGROUND Video-assisted (VATS) lung lobectomy can be associated with stronger postoperative pain than is commonly believed. It is generally accepted to introduce multimodal analgaesic strategies based on regional blockade, opioids and non-steroidal anti-inflammatory drugs. However, there is still no consensus regarding the optimal regional technique. The aim of this study was to compare the a...
