Active clinical trials for "Pain, Postoperative"

Although laparoscopic cholecystectomy is a minimally invasive surgery with many advantages, it is one of the operations with high postoperative pain scores. Opioids are frequently used to prevent postoperative pain. Due to the side effects of opioids, the amount of use is tried to be reduced. Regional anesthesia techniques can be used to minimize opioid consumption. Erector spina plane block was first described in 2016 by Forero et al. in the treatment of thoracic neuropathic pain. Since then, ESP block has been used as an anesthetic and analgesic technique. It is applied by injecting local anesthetic into the fascial plane located between the erector spina muscle and the transverse process of the vertebra. Several high-level studies have shown that the ESP block can be used to reduce postoperative pain after gastrointestinal surgery. Several studies have evaluated the effect of ESP block for pain relief after laparoscopic cholecystectomy. ESP block has been applied unilaterally or bilaterally in various studies. However, in the current studies in the literature, the advantages or disadvantages of the bilateral application of the ESP block compared to the unilateral application have not been evaluated. In this study, the investigators aimed to evaluate postoperative pain by applying ESP block to patients who underwent laparoscopic cholecystectomy and to evaluate the advantages of unilateral or bilateral application of ESP block over each other.

This study compares the efficacy of Dexmedetomidine as an adjuvant to Bupivacaine in Ultrasound Guided Transversus Abdominis Plane Block versus Caudal Block for post-operative analgesia in children undergoing congenital inguinal hernia repair especially to provide prolonged post-operative analgesia and decrease opioid consumption.

Osteopathy is an alternative healthcare that seems effective in relieving the pain of patients. The main purpose of this study is to evaluate the efficacy of preoperative osteopathic care in patients undergoing total knee arthroplasty (TKA) for osteoarthritis. The secondary objectives are to assess pain during the first postoperative month on a VAS and knee function and quality of life at 6 months and 1 year. Our hypothesis is that osteopathy will decrease postoperative pain and increase knee function.

Chronic Pain after Cholecystectomy is a well known problem. One theory is that it is due to persisting inflammation. The purpose of the study is to measure inflammatory factors in cerebrospinal fluid and blod at patients 12 months after the operation. DNA-samples are collected to examine genetical factors, important for perception of pain, and the development of chronic pain.

Previous studies have shown that chronic pain after hysterectomy is common. The aim of this study is to investigate the incidence of chronic pain after vaginal or laparoscopic hysterectomy for benign reasons. The aim of this prospective study is also to study the role of anesthetics, surgery and other possible predictors for pain 6 months after hysterectomy.

The purpose of this study is to find a more accurate postoperative pain assessment for teenager patients. This is important because a patient should not have a very strong pain medication such as morphine if the pain is just mild.

Postsurgical pain becomes chronic when it lasts more then two months after surgery. A neurogenic or neuropathic pathogenesis is hypothesized for this event that reaches high rates after urologic and gynecologic surgeries. Palmitoylethanolamide (PEA) binds to mast cells and regulates pro-inflammatory factors release, without adverse events. The investigators assume that perioperative administration of PEA can reduce chronic postsurgical pain incidence of patients undergoing to urologic and gynecologic elective surgery.

There is a large variability of postoperative pain intensity and of the drug doses necessary to alleviate this pain. The investigators hypothesis is that a measurement of nociception at the end of surgery, using either the RIII reflex threshold, measures of heart rate variability or the pupil dilatation reflex measured by pupillometry, in relation to the doses of opioids used intraoperatively will yield a prediction of postoperative pain.

Given as a single perioperative injection, SKY0402 could provide adequate, continuous, and extended pain relief that could greatly simplify postoperative pain management, reduce the need for repeated administration, and minimize episodes of breakthrough pain.

This is a chart review. The aim of this study is to investigate the effectiveness and side effects of very low dose morphine administered caudally to children that went to surgical procedures that used caudal anesthesia. The study compares caudal block with Bupivacaine (1 ml kg_1 of bupivacaine 0.25% and saline 0.02 ml kg_10) with very low dose morphine (a mix of 1 ml kg_-1 of ropivacaine 0.2% and preservative-free morphine: 10 µg kg-1).
