Active clinical trials for "Pain, Postoperative"

This research project intends to look at the effect that a certain type of freezing injection, called a paravertebral block, has on the pain after an operation for breast cancer, the amount of pain relief that is needed and the side effects from this pain relief. The hypothesis is that the paravertebral block, in combination with a general anesthetic will reduce both pain scores and the amount of strong pain killers (opioids) that is needed. This will reduce the side effects of the pain killers such as nausea and vomiting. This will be assessed by comparing it a general anesthetic with pain killers given through the intravenous (IV) as is routine practice. Patients requiring breast cancer surgery, who agree to be involved in the trial, will be randomly allocated into two groups: both groups will receive a block, then a standardised and optimised general anesthetic. In one group however the block is simply a small injection under the skin (a sham block), whereas the other group will receive a proper paravertebral block prior to this. Both groups will receive opioids as necessary, depending on both their bodies reaction during the surgery and their pain scores when they wake up. The paravertebral block is a very safe procedure with a very low side effect profile, and many studies have shown a benefit in breast cancer surgery. The investigators would like to assess this in our own practice. The block is normally inserted under some light sedation, with freezing into the skin initially. It is normally very well tolerated. The sham block will also be performed under light sedation and freezing into the skin. The patients will not be able to tell whether they are having the sham block or the paravertebral block, because both are very well tolerated. There are no potential complications from the sham block.

This randomized controlled trial will evaluate the effects of perioperative intravenous (IV) acetaminophen on postoperative narcotic consumption and pain scores in subjects undergoing vaginal reconstructive surgery. One hundred subjects will be randomly assigned to receive either IV acetaminophen or IV placebo. Those in the IV acetaminophen group will receive 1000mg IV every 6 hours for 24 hours beginning prior to anesthesia induction. The control group will receive placebo saline infusions at the same time intervals. All subjects will receive as needed (prn) IV narcotic for additional pain relief. Visual analog scales (VAS) regarding pain will be evaluated at 18 and 24 hours postoperative and immediately prior to discharge. We will also collect total IV narcotic consumption. We hypothesize that subjects receiving IV acetaminophen will have lower VAS scores and decreased total narcotic consumption in comparison to the control group.

Postoperative hyperalgesia has been reported after intraoperative administration of small or high-dose remifentanil. Cyclooxygenase inhibitor exhibit preventive effects on the development of opioid-induced hyperalgesia. The aim of this study is to evaluate the preventive effect of intravenous ibuprofen (Caldolor®) on remifentanil-induced hyperalgesia

The primary objective is to demonstrate that SKY0402 is superior when compared to bupivacaine HCl in the management of postoperative pain for patients undergoing total knee arthroplasty.

Exaggerated pain and hyperalgesia are major issues after surgery and can lead to chronic pain. Opioid are parts of pain sensitization processes but remain absolutely necessary in the intraoperative period. NMDA receptor antagonists succeed in reducing this pain sensitization process. Recent studies show that in pain and opioid-experienced rats (POER) fentanyl ultra low doses do not induce analgesia, as observed in naive rats, but hyperalgesia. This is the first demonstration that a drug can induce opposite effect depending on individual history. We also observed a strong correlation between this hyperalgesic response in POER and the intensity of hyperalgesia they develop later, after inflammatory or surgical pain. The main aim of this study is to measure the dose effect response to fentanyl "ultra low doses" on human volunteer's nociceptive threshold, to determine if such an opposite response profile can be revealed.

In this study,the investigators aimed to examine the effect of electroacupuncture application on the amount of pain felt by patients after periodontal surgery. The main question it aims to answer is there any efficiacy of electroacupuncture application on postoperative pain reduction. Participants will get periodontal flap surgery treatment with/without electroacupuncture Researchers will compare EA and control groups to see if there is any relationship between acupuncture application and postoperative pain

Aim is to assess the postoperative analgesic efficacy of SPSIPB and its effect on opioid consumption in patients undergoing shoulder surgery.

Pain can be quite severe after thoracic surgery and effective pain control is highly effective in preventing secretion accumulation, atelectasis, infection and hypoxemia. The objective was evaluate the effect of a connective tissue massage on pain, applied analgesic amounts and length of hospitalization of the patients.The study was conducted at a thoracic surgery department of university hospital in Turkey. Fifty-four patients with operated by the posterolateral thoracotomy method participated.The patients were randomly allocated to 1 of 2 groups: a control group (n27) and the experimental group (n27). Standard medical treatment, care and pulmonary rehabilitation program were applied to both groups. In addition, a total of 5 sessions of connective tissue massage were applied to the experimental group. Pain level of the patients was evaluated at every 24 hours as of the zeroth postoperative day. VAS was used as a one-dimensional scale for pain assessment. Totally applied analgesic amounts and length of hospitalization of the patients were recorded.

Objective: To compare the effect of dry heat versus moist heat application on episiotomy wound healing and pain among postnatal mothers. Research hypothesis H0: Postnatal mothers who apply dry heat on their episiotomy wound experience the same wound healing and pain as those who apply moist heat. H1: Postnatal mothers who apply dry heat on their episiotomy wound experience faster wound healing and less pain than those who apply moist heat. H2: Postnatal mothers who apply moist heat on their episiotomy wound experience faster wound healing and less pain than those who apply dry heat.

The aim of study is to investigate the effects of active external warming of patient concurrently with application of ice to incision site on thoracotomy pain and analgesic consumption. The research is a quasi-experimental design with control and study groups.
