Active clinical trials for "Pain, Postoperative"

The purpose of this research study is to find out if taking Acetaminophen with Ibuprofen (e.g. Tylenol + Advil), a non-opioid regimen, provides the same type of pain relief after hand surgery compared to Acetaminophen and codeine (e.g. Tylenol 3), an opioid regimen.

This is a single-blind randomized clinical trial. Patients undergoing abdominal tumor surgery were recruited to participate in the study. Apart from routine treatment in the surgical intensive care unit, the subjects were randomly divided into two groups: Propofol group (Group P) and Dexmedetomidine group (Group D) and received continuous intravenous infusion of Propofol (infusion dosage range: 0.3 ~ 1.6 mg/kg/h) or Dexmedetomidine (infusion dosage range: 0.1 ~ 0.7 mcg/kg/h) according to their assigned group. Patients' hemodynamic status was monitored using a chest Bioreactance technique, Continuous Non-Invasive Cardiac Output and Hemodynamic Monitor at preset time points (time of recruitment [0h], 2, 4, 6, 12h and 24h). Clinical data such as vital signs, hemodynamic parameters, laboratory results, fluid volume and drugs used were also recorded.

Spinal fusion is a painful surgery, and control of postoperative pain is difficult. Several studies have indicated that appropriate pain treatment protocols reduce postoperative morbidity, improve the results of the surgery, and decrease hospital costs

Single center double blind randomised controlled trial. 60 subjects. Giving lidocaine IV or saline to patients due to robot assisted colorectal surgery. Primary outcome is cumulative morphine consumption at 24 hours.

The purpose of our study is to evaluate whether utilizing ultrasound assessment during caudal epidural injection can reliably identify unrecognized and unsuccessful nerve blocks during the procedure, guide proper technique, and alter pain management outcome measurements for patients. Patients will be randomized to a group either undergoing caudal injection by a trainee using typical techniques or by using typical techniques in addition to ultrasound for confirmation of successful injection. The patients enrolled in this study will have the same intraoperative care, in line with the standard of care. Data will be collected intraoperatively and postoperatively on pain scores, time for performance of caudal block, and perceived success of the block. There will be no direct benefit to the patients enrolled in this study, but future patients may benefit from the use of ultrasound for the confirmation of a successful block.

The purpose of this study is: to document ketorolac disposition (concentration/time profile, protein binding, metabolism) and its covariates following intravenous (iv) administration of ketorolac right after caesarean section and to compare those observations (n=32) with non-pregnant state (n=8) (intra-subject PK comparison) to document biochemical tolerance of ketorolac to evaluate if optimalisation of ketorolac dose regimen during pregnancy and labor are appropriated and needed to quantify the neonatal exposure to ketorolac through excretion in the breast milk

The purpose of this study is to determine whether transdermal fentanyl patch

Abdominal surgery causes severe postoperative pain. Multi-modal pain therapy is usually applied but there is no perfect choice. It depends on physician's skill and situation. The best regimen is patient-controlled analgesia, but it requires an expensive equipment. Transdermal fentanyl patch, usually used in chronic pain relief, can steadily release fentanyl into blood stream for 72 hours, but it has slow onset of 12 hours. Hypothesis: If Transdermal fentanyl patch is applied 10-12 hours before surgery, it may provide good analgesia for 72 hours.

We hypothesize that preoperative saphenous nerve block (SNB) in combination with periarticular local infiltration provides better post operative pain relief (POPR) profile as compared to local infiltration alone

This study was designed to assess whether the injection of local anesthetic into the nerve (intraneural), as opposed to around it (perineural), leads to longer anesthesia and analgesia of the leg. Some reports of accidental intraneural injection mention an extremely long duration. When different drugs and doses were evaluated in a clinical trial of intraneural injection, a longer-than-expected duration was reported. The investigators will compare the two types of injection using the same drug, so as to determine if there is an actual difference in duration.
