Active clinical trials for "Pain, Postoperative"

The aim of this study is to determine the postoperative course including effects on the quality of life following soft palate surgery with radiofrequency knife (RAUP).

Intrathecal morphine causes intense itching which is very bothersome. Nalbuphine antagonizes this effect when given intravenously. This trial is to find out if nalbuphine added to intrathecal morphine has an effect on morphine related pruritus while still maintaining adequate analgesia.

This study was to evaluate the efficacy and safety of intravenously administered ibuprofen 400mg and 800 mg q6h for the management of moderate to severe postoperative pain in Chinese population.

Erector spinae plane block(ESPB), which is firstly used for thoracic neuropathic pain, is newly developed and highly promising fascial plane block for providing postoperative analgesia for a great deal of surgeries including breast surgery. The investigators aim to study efficacy of ESPB for patients who undergone breast cancer surgery and is expected to benefit from opioid-sparing effect of this technique.

To investigate if the level of preoperative lower back pain has the effect on the acute postoperative pain after gynecological laparoscopy

a comparison shall be conducted between dexamethasone accompanied by bupivacaine, on one hand, and dexmedetomedine accompanied by bupivacaine, on the other hand for pain-free knee arthroscopic surgeries.

Mandibular 3rd molars are the most commonly impacted teeth in oral cavity followed by maxillary 3rd molars and maxillary canines respectively. Impaction is a condition where a tooth fails to erupt in its final functional position, theoretically owing to inadequate space distal to the second mandibular molar and the anterior border of the ascending ramus of the mandible . Surgical removal of the third molar is the most common procedure carried out by a maxillofacial surgeon in the dental office. Surgical extractions are time consuming, expensive and cause morbidities such as pain, swelling, dry socket, trismus, and nerve injury when compared to non-surgical extractions. Various classifications have been proposed for mandibular 3rd molars, most common of which, is based on angulation of impacted tooth to the long axis of 2nd molar. Distoangular impacted 3rd molars are very difficult to remove because of lack of space distal to the tooth and lack of interdental space available for the application of elevator. Cowhorn forcep engages between the bifurcation of the mandibular molars and below the bone crest and causes displacement of tooth by upward movement or by splitting mesial and distal root. In our study cowhorn forcep are fist placed between 2nd and 3rd molar below the cementoenamel junction after its placement an apical pressure in applied and this rotation results an upward and distal movement and displacement of impacted tooth from the socket which then can easily be removed with cow horn forcep or molar crown forcep. The aim of our study is to present the minimal invasive technique for the extraction of distoangular and vertical impacted mandibular 3rd molars using cow horn forcep in comparison to conventional surgical techniques to avoid complications associated with open surgical techniques . METHOD: Total 128 patients will be recruited and divided into 64 patients in each group (two groups) attending in Dr. inshrat ul ebad institute of oral health sciences, Ojha, fulfilling inclusion criteria and undergoing extraction of 3rd molars will be included in this study. The participant will be briefed about the nature and purpose of the study. They will be ensured that their information will be used for the study purpose only. Informed consent from the participants will be obtained. Complete history from the patients will be taken and pre-operative evaluation will be done by clinical (pain and swelling) and radiographical (angulation of the tooth) examination. All the patients would undergo extraction of 3rd molars via both either conventional surgical technique or the proposed technique in the study. Followup will be done after 3 days to evaluate the same post-operative variables (pain and swelling) after extraction of 3rd molar and both techniques will then be compared in terms of variables measured.

General anesthesia is a combination of hypnotic drugs and opioid analgesics. Modern general anesthesia aims to treat nociception induced by surgical stimulation while avoiding an overdose of opioid analgesics and reducing side-effects of opioid administration. Quality and safety of general anesthesia are of major clinical importance and can be improved by adjusting the opioid analgesics to the optimal individual dose needed. In the current clinical practice, the opioid dosage is usually chosen by clinical judgment, though recently different monitoring devices estimating the effect of nociception during unconsciousness have become commercially available. Nevertheless, the impact of nociception-monitor-guided opioid administration on the administered amount of opioid, postoperative short-term recovery, and long-term outcome is inconclusive. This study aims to investigate the predictive power of different nociception monitoring systems for the prediction of moderate to severe immediate postoperative pain from nociception indices measured before awakening from general anesthesia.

Observational study that evaluate the cardiovascular and neuropsychiatric side effects of ketamine analgesic infusions for acute pain

Pain is common for the first 2 days after major craniotomy. Inadequate analgesia induced sympathetically mediated hypertension may lead to an increased risk for post-operative complications, such as arterial hypertension, intracranial hemorrhage, prolonged hospital stay, and mortality.Pain after craniotomy derives from the scalp and pericranial muscles.Scalp block with local anesthesia seems to provide effective and safe anesthetic management.Scalp block can be performed by directly blocking the six different nerves that provide the sensory innervation of the scalp in neurological surgery.Even if adrenaline as an additive agent, scalp block using 0.5% or 0.75% bupivacaine with adrenaline could only improve postoperative analgesic for up to six hours after craniotomy.However, pain is common for the first 2 days after major elective intracranial surgery, and the relatively short analgesic time of scalp nerve blocks does not seem to meet the requirements of craniotomy. Therefore, how to improve the quality and duration of scalp nerve blocks with local anesthetics is of great significance.Parecoxib is a NSAIDs that specifically inhibits the enzyme COX-2.Liu et al firstly applied parecoxib as an adjuvant to local anesthetics on peripheral nerve blocks and reported 20 mg parecoxib added to ropivacaine injected locally on the brachial plexus nerve prolonged the motor and sensory block times of the nerve blockade and ameliorated postoperative pain intensity for patients receiving forearm orthopaedic surgery. However, there has not been reported about local application of parecoxib on scalp nerve blocks. The investigators postulate that parecoxib may be also ideal for scalp nerve blocks for relief of post-craniotomy pain, and further research is needed. The APONIA trial aims to establish whether scalp blocks with a mixture of ropivacaine plus parecoxib is able to relieve patients' postoperative pain compared with local anesthetics alone, thereby potentially changing medical practice.
