Filter by:Thoracotomy is one of the most painful operations known. Therefore, it causes severe acute pain. If pain is not controlled, it increases the frequency of postoperative pulmonary complications and postoperative morbidity. It can even cause chronic pain in the future. Thoracic epidural analgesia (TEA) is the gold standard method in the treatment of pain after thoracotomy. Thoracic paravertebral block (TPVB) is known as the most effective method after TEA. The fact that TPVB has fewer side effects than TEA increases the use of TPVB. There is no consensus on the dose of analgesia in studies. In the literature, volumes between 20 ml and 30 ml are frequently used for TPVB in recent years. This study, it was aimed to compare the efficacy of 20 ml, 25 ml, and 30 ml volumes of TPVB with local anesthetic at the same concentration (0.25% bupivacaine) on postoperative analgesia in patients undergoing thoracotomy.
The aim of this research is to study and compare the efficacy and safety of single injection erector spinae plane block and thoracic paravertebral block in prevention of post herpetic neuralgia in patients with acute thoracic herpes zoster.
Pain after hepatectomy can interfere with the patients' recovery and may contribute to developing long term pain. Opioids, e.g. morphine, fentanyl, sufentanil, works well for postoperative analgesia, but have several side effects such as nausea, vomiting and itching which may be severe enough to affect patients' recovery. In some cases, opioids may cause constipation and urinary retention within the first 24 hours after surgery. Thus, several ultrasound-guided nerve block procedures have been applied to provide postoperative analgesia. Ultrasound-guided thoracic paravertebral block (TPVB) is one of the most used nerve block methods using for post-hepatectomy analgesia. However, in some cases, ultrasound-guided TPVB can cause pneumothorax, hemopneumothorax, and higher block level. The quadratus lumborum block (QLB) is a new developed nerve block which can provide a widespread analgesic effect from T7 to L1. Therefore, this study is to determine whether QLB or TPVB have a better pain control with fewer side effects and complications after laparoscopic and open hepatectomy. The adequate pain control will be assessed by their visual analogue score (VAS) and the postoperative quality of recovery scale (QoR-15, Chinese Version). Additionally, the side effect and complications profile of these two nerve block techniques will also be recorded and compared.
