Active clinical trials for "Pain, Postoperative"

This study will explore nurses' pediatric postoperative pain management knowledge and clinical practices. The aim is to evaluate if a tailored educational intervention will improve nurses' knowledge and attitudes of pain management and pain management practices. The intervention offered is education and skills training. The study has a pre-post design and a comparison group. Data is collected before the intervention is started (baseline T1) and again one month (T2) and six months (T3) after the intervention. Nurses working in six postoperative units are participating. The units are the largest pediatric postoperative units of each of the six university hospitals covering all health regions in Norway. Three different approaches will be used to collect data (survey with questionnaire, observations of clinical practice, and interviews with children).

Postoperative pain (POP) is frequently underestimated in general and little data are available particularly for POP after vitreoretinal surgery (VRS). The investigators will conduct a 1-year retrospective study on patients undergoing VRS at "Careggi Hospital" . The aim of the study will be to observe the amount of POP, its time course, factors associated with its appearance and finally the efficacy of the pain protocol that is in use.

The aim of this study was to evaluate the effect of simultaneous length control during root canal preparation on postoperative pain compared with separate working length determination and root canal preparation using electronic apex locator. During preparation of root canals, loss of working length (WL) can lead to instrumentation beyond the predefined apical limit of the preparation. This effect is mainly attributed to straightening of the root canal during instrumentation. Some studies showed, that this kind of over instrumentation as well as under instrumentation can adversely affect the outcome of the endodontic treatment, while it remains uncertain what exactly is the most favorable extent of the apical limit of root canal preparation. Furthermore, all endodontic instruments produce apical extrusion of debris, even when the preparation is kept within the confines of the root canal. Consequently, preparations ending in the periapical tissue will produce a greater amount of debris extrusion that could elicit a neurogenic inflammatory response resulting from an irritation of the periodontal ligament with subsequent postoperative symptomatic apical periodontitis. Therefore, it seems favorable to control the determined WL during root canal preparation to avoid preparations ending in the periapical tissue.

To investigate the efficacy of preemptive pudendal nerve blockade on postoperative pain, after posterior vaginal repair, below the level of ischial spine, excluding uterine suspension procedures that are higher than the coverage of the block. Primary outcome: The primary outcome measures of the study visual analogue pain scores and postoperative analgesic consumption.

For patients who underwent two-stage replacement of both knee joints (one knee surgery - one week term- the other knee surgery), postoperative pain and analgesic usage with patient-controlled analgesia (PCA) increased at the second stage, which suggests that central sensitization occurs within a short period (one week) in patients who undergo total knee arthroplasty (TKA). Neurosteroids act on NMDA and AMPA receptors, GABAa receptors, and voltage-dependent Ca2+ or K+ channels of sensory neurons to increase invasive or neuropathic pain and, conversely, to exhibit analgesic and anticonvulsant effects. These actions mean that the neurosteroid acts as an endogenous regulator of pain control and central sensitization. The purpose of this study is to confirm that the hypothalamus-pituitary-adrenal (HPA) axis, which is the main body of endocrine neurosteroid, is associated with increased pain sensitivity after TKA. The concentrations of cortisol and dehydroepiandrosterone (DHEA) in the saliva of patients who undergo two-staged bilateral knee replacement surgery (one knee surgery - one week term- the other knee surgery) will be measured at each stage and analyzed for correlation between concentration-related changes of HPA and postoperative knee pain variations.

Total knee arthroplasty (knee replacement) is a common orthopedic procedure for osteoarthritis. This procedure is performed either under general anesthesia or spinal anesthesia; after the procedure in the recovery room, these patients undergo adductor canal block, which is a nerve block to provide 8-14 hours of postoperative pain control. For this nerve block, 15-20 ml of local anesthetic is combined with adjuvant medications to improve the quality of pain control as well as the duration of pain relief. The primary local anesthetic used for adductor canal block is ropivacaine, and the commonly used adjuvants are epinephrine and dexamethasone. There is conflicting data available in the literature regarding efficacy of addition of clonidine to the local anesthetic injection in peripheral nerve blocks, and there is no data assessing the efficacy of this medication in adductor canal blocks. Once the consent process is completed, patients are enrolled in two arms. Upon conclusion of surgery, a sealed and coded envelope with either clonidine or the placebo syringe will be given to the acute pain service staff performing the nerve block. This will be mixed with local anesthetic solution and injected in the adductor canal under ultrasound guidance. The primary outcome measure will be the duration of analgesia, which will be assessed as the time interval between placement of adductor canal block to the first request of opioid analgesic by patients (which will be obtained from hospital electronic medical records). Secondary outcomes will include: Duration of sensory block, which will be assessed as the time interval between injection of local anesthetic and report of postoperative pain of 3 or more on an 11 point scale (0=no pain; 10= worst pain imaginable) by the patient (this will be assessed every 4 hours). Duration of motor block, which will be assessed as the time interval between the onset of motor block to complete recovery of motor block by assessing straight leg raise strength (this will be assessed every 4 hours). Cumulative 24 and 48 hour opioid analgesic use. Post-block pain scores, evaluated by an 11 point pain score (0-10), which will be done every 15 minutes for the first hour after surgery and every 4 hours thereafter for 24 hours.

Purpose: Recent advances showed that ultrasonic implant site osteotomy is related with a decreased trauma and a better post operative healing of the surgical site if compared to the traditional drilling techniques. The micrometric bone cutting control and the operative advantages related to the piezoelectric approach is also characterized by a learning curve for the clinician in surgical practice and an increased operative duration of the procedure. The aim of this investigation was to compare the operative time, the post operative pain and the patients frequency of intake of painkillers in the healing period. Methods: A total of 75 patients were treated at the Unit of Oral Surgery (Department of Medical Sciences, Surgery and Health, University of Trieste, Italy) in a split mouth model: 75 drill-inserted implants (G1) and 75 piezoelectric device- inserted implants (G2). The Visual Analogue Scale (VAS) was performed to evaluate the post-operative pain at 15 days from the surgery. The operative time and frequency of intake of painkillers was measured.

The aim of study is to assess the effect of intraoperative use of magnesium sulfate in liver donating patients in reducing post-operative morphine requirements in early postoperative 24 hour in adult living liver donor.The authors hypothesize that magnesium sulfate can be used to efficiently reduce postoperative morphine consumption in the early 24 hours postoperatively as evident in other surgery types.

the investigators use usually a plane block for postoperative analgesia; if it suitable. İn laparoscopic patients; investigators used oblique subcostal transversus abdominis plane block; formerly. But in the last few months, the investigators have performed serratus intercostal (BRILMA) block with bilateral rectus sheath block. in this retrospective evaluation, the aim of the retrospective evaluation is to determine the effects of two block on postoperative opioid consumption.
