Active clinical trials for "Pain, Postoperative"

The aim of the study is to evaluate the analgesic properties of dexamethasone and to quantify the possible associated postoperative complications, such as wound infections and hyperglycaemia, in patients who underwent lobectomy, segmentectomy or atypical resection surgery with a mini-thoracotomy approach or video-assisted thoracoscopic surgery (VATS).

Cleft palate repair is a common surgery in children.. As such children with cleft palate tend to have a compromised airway due to associated congenital anomalies like Pierre Robin syndrome, Treacher Collins syndrome etc. After surgical correction of cleft palate, they are more prone to develop post-operative respiratory difficulty due to narrowed airway, increased secretion, pain and sedation caused by opioids. Hence, regional block, using local anesthetics, becomes a good option in this surgery. The supremacy of bilateral infraorital block using levo bupivacaine over intravenous fentanyl as well as over peri-incisional infiltration in has been shown .Levobupivacaine was developed after Ropivaciane was noted to be associated with less no of adverse events.. Ropivacaine has been used for peripheral block in children for surgical pain. Though the use of Levobupivacaine in regional blocks in facial surgeries has been well established, studies are still needed to establish its supremacy over Ropivacaine in cleft palate surgeries

The investigators designed a multi-center prospective randomized controlled trial to study the influence of the type of anesthesia on postoperative pain after laparoscopic colorectal cancer surgery. Half of the participants will be anesthetized with propofol and remifentanil, while the other half will be anesthetized with sevoflurane and remifentanil during the surgery. The investigators will measure opioid consumption and pain score in the acute postoperative phase.

Arthroscopic shoulder surgery is often associated with moderate to severe postoperative pain that may interfere with patients' early mobilization, recovery and quality of life. In addition, by using an effective analgesic technique, a patient may experience less nausea, vomiting and drowsiness after surgery that are associated with the use of opioids to manage postoperative pain. Erector spinae plane block (ESPB) has been used in many different indications for acute pain treatment at different thoracic and lumbar levels. Recently, staining the roots of the brachial plexus has been reported in a cadaveric study of the cervical ESPB (1). However, there are only few case reports related to efficiency and safety of this newly defined cervical ESPB technique (2) . The primary objective of this randomized controlled is investigate the post-operative analgesic effectiveness of ultrasound guided single-shot cervical ESPB for patients undergoing arthroscopic shoulder surgery in comparison to those receiving conventional parentheral opioid analgesia alone. Secondary objective is testing the safety of this newly defined block in terms of incidence of complications.

Transcranial direct current stimulation (tDCS) is a technique of noninvasive cortical stimulation allowing significant modification of brain function used. Clinical application of this technique could be helpful for pain, Parkinson's disease, dystonia, cerebral palsy and dementia etc. And tDCS is safe with only mild, transient adverse effects. But there is few studies focused to postoperative states. The aim of this project is to reveal the effect of tDCS for postoperative pain after total knee replacement surgery,

Breast cancer is the most frequent in women. Early diagnosis and recent treatments have improved overall mortality. However, chronic pain (pain lasting more than 3 months after surgery) remains a public health problem with impact on quality of life for these patients. The incidence of pain has been reported up to 25 to 60% of patients in the literature, even many years after a radical mastectomy. The neuropathic component of the pain is usually underestimated. In a prospective cohort study we have demonstrated that 43% of patient needed on average 5mg of morphine intravenously in the recovery room after a conservative breast cancer surgery, despite a multimodal regimen of analgesic drugs. In the same study, 40% of patients reported persistent pain 3 months after the surgery. To improve the analgesia in such a population, we decided to introduce regional analgesia technique (serratus block) systematically. This became our gold standard in our daily practice. We would like to assess the efficacy of such regional analgesia techniques on opioids consumption in the recovery room and the incidence of pain 3 months after conservative breast cancer surgery.

Acupuncture research in regards to PONV has been fairly well established, however, studies about perioperative pain control and acupuncture are a little more murky. In 2008, a meta analysis looked at randomized controlled studies and found that while acupuncture was shown to decrease pain, there were limitations including credible placebo or sham intervention, and thus, blinding. The main purpose of this feasibility trial is to determine whether or not adequate blinding is possible in the intraoperative setting with the patient sedated.

The investigators will compare whether patients will have better pain control if they were to receive (PEC I/II block) before surgery or after mastectomy.

Effective pain control following surgical procedures is a goal for both the patient as well as the medical staff caring for them. There have been numerous studies evaluating differing treatment pathways, but most studies have relied on the Visual Analog Scale (VAS) or Numerical Rating Scale (NRS) to evaluate outcomes. These scales are subjective score given by the patient with no objective data input, therefore making comparisons subject to possible bias. There are no known studies comparing the pain scores provided by the patient to the surgical team compared to the nursing staff caring for the patient. The aim will be to compare these values to see if patients are consistent in their pain rating.

During the current pain monitoring system the patient is awake and he/she is asked to give a numerical scale rating from 0 (no pain) to 10 (extreme pain). The purpose is to correlate the non-invasive measurements of the prototype device ANSPEC-PRO with these numbers to develop later a method/algorithm for automatic evaluation of pain (objective measurement of pain). The measurement is done using standard ECG electrodes placed in the hand palm of the patient. The patient feels nothing during the observations, perhaps irritation of skin may occur as result of long time measurement. As a comparison to the investigators prototype, a commercial device is also used in (randomly selected) patients, i.e. the MedStorm device. The study will try to answer the following questions: Are the measurements with the ANSPEC-PRO correlated with the NRS values? What is the (mathematical) relationship between the measured values and the NRS? Is there difference between the two devices in measuring pain levels? And what is this difference if pain alleviation medication is given to the patient? A number of 26 patients is envisaged for this study, equally distributed to be evaluated with the two devices.
