Filter by:This will be a prospective study to determine the association between specific genotypes, epigenetics, behavioral, social and biological factors, with the phenotypes, defined by pain perception, postoperative pain, analgesic effects, side effects to perioperative analgesics, chronic postoperative pain, and gene expression in patients following pectus excavatum repair.
Tourniquet use during total knee replacement (TKR) improves visibility, significantly decreases intra-operative blood loss and reduce operative time. However, tourniquet use also has a negative effect on postoperative pain, postoperative range of motion(ROM), wound complication, deep vein thrombosis (DVT), pulmonary embolism (PE), thigh muscle strength, and functional recovery after TKR. Therefore, the investigators conducted a three-arm prospective, randomized, controlled trial study to compare the efficacy of different tourniquet pressure used between systolic blood pressure + 75 mmHg, systolic blood pressure + 100 mmHg, and systolic blood pressure + 150 mmHg.
The purpose of this study is to evaluate the efficacy of two methods of administering an adductor canal block (ACB) following total knee arthroplasty (TKA); intraoperative surgeon performed intra-articular adductor canal block (IACB) and anesthesiologist ultrasound guided ADC in the post-anesthesia recovery unit (PACU).
This is a prospective randomized clinical trial study to investigate two main aspects. The first aspect is to investigate the efficacy exposure to green light emitting diode (GLED) in reducing postoperative opioid medications requirements by 20% as the primary outcome amongst patients scheduled for elective total knee replacement surgery (knee arthroplasty). The second aspect is to reduce postoperative pain by 30%, improve preoperative anxiety by 30%, and improve the quality of sleep pre and postoperatively by 30%. Seventy participants scheduled for elective unilateral primary total knee arthroplasty (total knee replacement) will be recruited from the pain clinic or from the orthopedic surgery clinics at Banner-University Medical Center by the pain or orthopedic physicians who are key personnel of this study. Once a participant is identified, he/she will meet with one of the research team members to explain the nature of the clinical trial and undergo a standard of care medical history gathering and baseline physical examinations. If the participant meets all the inclusion and have no exclusion criteria, he/she will be presented with a written consent in English to explain all the risk and benefits of this clinical trial. Once a participant signs a consent, he or she will be randomized by the study statistician, in a 1:1 ratio to either a GLED group (treatment) or white light-emitting diode (WLED) group (control). The participant will be trained on how to use the light device by one of the research team members. All participants will be exposed to either GLED or WLED for 8 weeks prior to surgery and two additional weeks after surgery.
The aim of this study was to evaluate an effect of pre - incisional single injection of low-dose ketamine on postoperative pain after remifentanil infusion in patients undergoing laparoscopic gastric bypass and gastric plication surgery. Ketamine is an old general anaesthetic. Low doses of it might be used as a adjunct in postoperative analgesia.The investigators expect that the low-dose ketamine reduces postoperative pain after bariatric surgeries.
Bariatric surgical procedures are associated with low short-term mortality and may be associated with long-term reductions in all-cause, cardiovascular, and cancer-related mortality. This surgeries are major surgeries include risk of mortality still. Melatonin is a hormone secreted from the pineal gland. Melatonin is an antioxidant, antinociceptive, hypnotic, anticonvulsant, neuroprotective, anxiolytic, sedative and analgesic. Melatonin is neurohormone with the profile of a novel hypnotic-anesthetic agent. The purpose of this study is to investigate the preoperative, perioperative and postoperative melatonin levels in bariatric surgery under general anesthesia and to investigate the relationship between melatonin level and analgesia requirement.
The use of opioid during surgery can cause side effects and may delay hospital discharge. Some studies have shown balanced sparing opioid anesthesia can optimize the side effects and and the time of discharge. In this compared controlled randomized study the aim is to evaluate the intraoperative and postoperative pain, hemodynamic effects, nausea/vomiting, postoperative ileus, sedation, urinary retention, time of discharge PACU Post anesthesia care unit and hospital.
To evaluate the use of maternal opiates for pain control post cesarean delivery in those patients that received intravenous acetaminophen 1000 mg in 150 mL of normal saline, infused 30 minutes prior to incision compared to placebo. A comparison of post delivery length of stay in both study groups will be evaluated for cost effectiveness of the use of acetaminophen. a secondary purpose is to determine the levels of neonatal acetaminophen in cord blood at the time of delivery, since this has never been studied.
The purpose of this study is to determine whether liposomal bupivacaine (long acting injectable anesthetic) provides greater post operative pain relief compared to the standard post operative pain regiment for tonsillectomy patients.
Postoperative pain following tonsillectomy or adeno-tonsillectomy in children is severe and sometimes last for days. Sufentanil is used by epidural route for postoperative analgesia in children. There are few reports about its use for postoperative analgesia by continuous intravenous infusion. Its complications include , hypoxia, sedation, pruritus ,nausea and/or vomiting. The investigators design this protocol to test efficacy of analgesia of three different rates of continuous intravenous sufentanil infusion for postoperative pain management following coblation tonsillectomy or adeno-tonsillectomy in children. The investigators also compare incidence rate of complications for three groups.
