The goal of this study is to compare how well these two medications work in terms of safety and effectiveness when patients have hip replacement surgery that allows them to go home the same day. The study will look at how long it takes for feeling and movement to return after the numbing medication wears off, how many patients can go home on the same day as their surgery, and how long patients need to stay in the recovery area and hospital. Other things that will be measured include how much pain patients feel after surgery using a number scale, whether patients have difficulty urinating, if they experience nausea or vomiting, how much pain medication they need after surgery, how satisfied patients are with their care, blood pressure and heart rate during the procedure, how quickly the numbing effect starts, and whether the numbing medication works well enough during the surgery.

Patients in this study will receive one of the two numbing medications as a single injection before their hip replacement surgery. The study is designed so that neither the patients nor the doctors know which medication is being given until after the study is complete, which helps ensure fair results. The medications will be given at specific doses, with ropivacaine given at up to sixteen milligrams and bupivacaine given at up to thirteen and a half milligrams, both administered once on the day of surgery.

The group receiving General Anaesthesia will be given remifentanil hydrochloride and propofol through an intravenous infusion, which is a method of delivering medication directly into a vein. The group receiving Spinal Anaesthesia will receive medications through intrathecal use, which means the medicine is injected into the fluid surrounding the spinal cord. The medications used for this method include bupivacaine hydrochloride, epinephrine, sufentanil citrate, or fentanyl citrate.

During the course of the study, researchers will observe the time it takes for patients to move from the start of anesthesia through different stages of recovery. Information will be gathered regarding the use of analgesics, which are pain-relieving medicines, and the levels of pain experienced after surgery. The study will also track the ability of patients to move around, such as walking, and will monitor any unwanted side effects or the need for blood transfusions to ensure patient safety and recovery quality.

The purpose of this study is to find out how different doses of dexamethasone affect quality of life for patients in the three months after hip replacement surgery. Quality of life refers to how well a person feels in their daily activities, including their physical comfort, ability to move around, and overall well-being. The study will compare the effects of the lower dose against the higher dose to see which one works better for helping patients recover and feel better after their surgery.

During the study, patients will receive one of the two doses of dexamethasone during their hip replacement operation. After the surgery, patients will be asked to complete questionnaires at different time points to measure how they are feeling and recovering. These questionnaires will ask about their quality of life, recovery progress, hip function, pain levels, and tiredness at various times following the surgery, including on days 1, 3, and 5, as well as at 30, 60, and 90 days after the operation. The study will help doctors understand which dose of dexamethasone might be more helpful for patients recovering from hip replacement surgery.

The purpose of the study is to determine if injecting these medications directly into the hip joint before surgery can reduce the need for additional pain medication after the operation. This is compared to a placebo injection, which does not contain active medication. The study will involve patients receiving their hip replacement surgery and will monitor their need for extra pain relief in the hours and days following the procedure.

Participants in the study will receive either the medication or a placebo before their surgery. The study will track how many patients require additional pain medication after the operation, as well as other factors like pain levels, side effects, and overall satisfaction with the pain management. The goal is to see if this approach can improve pain control and recovery for patients undergoing hip replacement surgery.

Participants in the study will receive one of the two anesthesia techniques. The medications used in these techniques include Levobupivacaine, a local anesthetic, and Sodium Chloride, which is often used as a solvent. The study will also include a placebo group to help compare the effectiveness of the treatments. The trial will monitor various outcomes, such as pain levels, muscle strength, and any side effects like nausea or sedation. Additionally, the study will track the need for extra pain relief, the use of opioids, and the length of hospital stay.

The purpose of this study is to improve postoperative care for patients undergoing hip replacement by identifying the most effective pain management technique. By comparing the PENG block and lumbar plexus block, researchers hope to enhance recovery and mobility after surgery, ultimately leading to better patient outcomes. The study is expected to run until early 2025, with recruitment starting in early 2024.

Participants in the study will be asked to stop taking their SSRI or SNRI medication for a short period before their surgery. The study will monitor how well patients manage without their medication and whether they experience any symptoms of withdrawal or a return of their mental health conditions. The study will also look at how many patients are able to reduce their medication dose if they cannot stop completely. Patients will be assessed at different times: at the start of the study, two weeks later, the day before surgery, and two months after surgery.

The study aims to understand the effects of stopping these medications temporarily and to gather information on how many patients can successfully do so. This information could help improve care for patients undergoing hip or knee replacement surgery who are taking SSRIs or SNRIs. The study will run until 2026, with recruitment starting in 2024.

Participants in the study will receive either the pain medication or a placebo. The study will monitor pain levels using a simple scale from 0 to 10, where 0 means no pain and 10 means the worst pain imaginable. This will be checked 8 hours after the surgery and at various times over the next two days. The study will also look at how much additional pain medication is needed during the first 48 hours after surgery and will track any side effects or complications that might occur, such as nausea or dizziness.

The study aims to provide valuable information on how to manage pain effectively after hip replacement surgery, potentially leading to better recovery experiences for patients. Participants will be asked about their pain experiences and overall recovery at different points in time, including the first and second days after surgery, as well as one week and one month later. This information will help assess the overall quality of recovery and the effectiveness of the pain management strategies being tested.

The purpose of the study is to assess both the helpful and potentially harmful effects of taking ibuprofen for eight days after surgery. Participants will be randomly assigned to receive either ibuprofen or an identical capsule that does not contain the active medication, known as a placebo. The study will monitor for any serious health issues, such as heart problems or bleeding, within 90 days after surgery. It will also track any side effects related to ibuprofen, like stomach discomfort or diarrhea, and compare them to side effects from other pain medications, such as nausea or constipation.

Throughout the study, participants will keep a diary of their symptoms and complete a health-related quality of life questionnaire. This will help researchers understand how ibuprofen affects recovery and overall well-being after surgery. The study aims to provide valuable information on the safe use of ibuprofen in managing pain after hip and knee surgeries.

Participants in the study will receive tranexamic acid through an infusion, which is a method of delivering medication directly into the bloodstream. The study will also involve the use of sodium chloride solution, commonly known as saline, which is often used in medical settings to provide hydration and as a vehicle for other medications. Additionally, some participants may receive apixaban, a medication that helps prevent blood clots, taken orally in the form of a tablet.

The study will monitor the participants’ hemoglobin levels before the surgery and on the eighth day after the surgery to measure any changes. It will also look at the concentration of tranexamic acid in the blood and other factors like the need for blood transfusions and the occurrence of any blood clots or other serious events. The study aims to provide valuable information on how to best use tranexamic acid to improve outcomes for patients undergoing hip replacement surgery.

Participants in the study will receive either nefopam or a placebo after their hip replacement surgery. The study will monitor the amount of morphine used for pain relief, as well as other factors like pain levels at rest and during movement, recovery of physical function, and any side effects from the medications. The study will also look at the long-term effects on pain and recovery, including how quickly participants can stop using walking aids like canes or crutches.

The safety of nefopam will be closely monitored, with attention to any serious side effects such as seizures, confusion, or allergic reactions. The study will also track any common side effects of morphine, such as nausea, itching, or urinary retention. Additionally, the study will assess the economic impact of using nefopam as part of a pain management strategy over a five-year period. The trial is expected to run until 2026, with recruitment having started in 2023.
