Active clinical trials for "Pain, Postoperative"

The purpose of this study is to determine the analgesic efficacy and safety of Meloxicam Injection in subjects undergoing abdominal surgery.

It reduces pain scores in patients with block and improves the quality of recovery in the postoperative period. In patients who will undergo spinal anesthesia, it will be questioned whether the application of the block before or after surgery makes a difference in the quality of recovery.

The purpose of this project is to determine if a change in patient reported pain, nausea and vomiting after total knee arthroplasty can be observed with the substitution of a post operative adductor canal block for a preoperative adductor canal block in the current established peri-operative pain protocol and if these changes lead to a decrease in opioid consumption (in morphine equivalents).

The investigators aimed to demonstrate that dexamethasone added as an adjuvant to local anaesthetic agent in suprainguinal fascia iliaca block for effective postoperative analgesia after knee arthroplasty would prolong the duration of sensory block and reduce postoperative pain intensity and analgesic consumption.

As the opioid epidemic shows no sign of abating, this national crisis deserves careful attention from all medical subspecialties. This includes reproductive endocrinology and infertility (REI), where opioids are primarily utilized for intraoperative and postoperative pain management for outpatient procedures such as oocyte retrievals, operative hysteroscopy, and laparoscopic myomectomy. The primary aim of this study is to evaluate whether or not the administration of rectal acetaminophen as an alternative analgesic at the completion of oocyte retrieval would reduce postoperative utilization of opioids (Tylenol with oxycodone) in fertility patients. This trial has the potential to provide practice-changing clinical information to the field of REI. The information gained can even translate to other ambulatory procedures and guide clinical practice. Primary objective of the study will be to identify the proportion of prescribed Acetaminophen and Narcotics utilized 3 days following oocyte retrieval.

The aim of this study is to perform a randomized trial to investigate if intraoperative surgeon administered TAP block reduces pain and use of oral and parenteral pain medications after repeat cesarean delivery. The investigators aim to compare surgeon administered TAP block with liposomal bupivacaine compared to standard treatment (i.e. no TAP block) with regard to the primary outcome of post-operative narcotic use.

A prospective cohort study comparing PENG block versus iliac fascia block with the aim of evaluating its effectiveness in the peri-surgical analgesia of intracapsular femoral fracture.

This is an observational clinical study aiming to further the wider understanding of patients who develop persistent pain after Thoracoabdominal Aorta surgery, a surgical cohort who are disproportionately affected. This will be undertaken through a prospective biospychosocial characterisation of the phenotype of patients undergoing this operation. Increasing numbers of patients are undergoing surgery on the chest for treatment of heart or lung cancer disease. Over the last twenty years, the medical community has become increasingly aware of the long-term effect of this surgery in producing persistent pain, approximately half of all survivors are still in pain around their surgical incision at three months postoperatively and beyond. There is currently no accepted method for preventing this phenomenon. The nervous system mechanisms for the development of persistent pain after surgery are unclear. Some studies suggest it may involve the patient's ability to dampen down pain signals travelling from the incision site to the brain. Humans have an in-built system that produces opiates as well as other pain-relieving molecules in response to injury, e.g. surgery. However, this response varies hugely from person to person and may even be impacted by the psychological state of the individual at the time of surgery. Some of these pain modulating mechanisms can be measured before and after surgery in patients using sensory testing, a robust and established objective method to assess patients'. Identifying patients who are most at risk of a persistent pain state will allow both academics and clinicians to investigate and better target appropriate treatments. Undertaking these longitudinal observational assessments will facilitate an improved mechanistic insight of the transition from acute to pathological pain, with the ultimate goal of improving outcomes for patients'.

The aim of the current study is to compare the analgesic effects of both drugs in patients with obesity undergoing bariatric surgery.

Patients who undergoing total knee arthroplasty under spinal analgesia will be recruited and randomly assigned to the following two groups according to the regimen of PCA: (A) opioid group who receive only fentanyl citrate 1200mcg for continuous infusion drug, (B) non-opioid group who receive ketorolac tromethamine 150mg with nefopam hydrochloride 100mg for continuous infusion drug. All the patients will receive additional fentanyl citrate as bolus injection drug if they need more analgesics postoperatively.
