Active clinical trials for "Pain, Postoperative"

Postoperative analgesia after corrective surgery of paediatric craniosynostosis is crucial in term of short and long-term outcomes. The objective of this observational case- control study was to evaluate the effectiveness of an analgesic technique based on the scalp block versus traditional pharmacological approach.

The purpose of this study is to evaluate the effect of perioperative opioid counseling within a specific group of patient population who are undergoing bilateral reduction mammoplasty.

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.

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.

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,

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.

Ultrasound guided interscalene nerve blockade with local anesthesia is a standard regional anesthetic technique for providing postoperative analgesia during shoulder arthroscopy and wide variety of shoulder procedures. There is a paucity of data regarding the effects of shoulder arthroscopy on ultrasound image quality, including the effects of muscle mobilization and the use of large volume irrigation and subsequent tissue absorption, though increased neck circumference and airway edema are known complications of arthroscopic shoulder procedures. The objective of the study is to determine if there is a difference in ultrasound image quality of the interscalene block anatomy, by Likert scale, pre- versus post-operatively in a cohort of patients undergoing shoulder arthroscopy who routinely receive blockade of the brachial plexus for postoperative analgesia. Further, if there are differences in imaging quality, correlations with surgical and patient factors will be studied.

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.

The purpose of this study is to compare sharp and blunt fascial entry during caesarean section.
