Filter by:After undergoing hernia surgery, hydrocelectomy or lower abdominal surgery, a child may experience some amount of pain in the post-operative period. As part of the anesthesia technique, the investigators routinely provide a nerve block done on the abdominal wall that will provide pain relief for at least 10 hours postoperatively. This is referred to as a TAP block. The purpose of this study is to determine if the nerve block performed with local anesthetic solution using a regular concentration solution vs. a diluted solution may offer different durations of pain relief.
The purpose of this study is to evaluate the analgesic effects of dexketoprofen trometamol, tramadol hydrochloride, pethidine hydrochloride and their combinations in laparoscopic Nissen fundoplication.
This study is being done to try to learn more about how a child's body breaks down bupivacaine, a local anesthetic medication that is being used for pain control. This study will provide information about how much medication gets into the bloodstream and how long it remains in the blood. Newborns and young infants often process drugs in their body in a different way than older children. This study will help the investigators determine how bupivacaine is broken down in the body of infants.
In preparation for future large-scale genome wide association studies, reliable methods must be developed for measuring perceived pain and for estimating the effects of potentially confounding factors such as appropriate covariates. The major objectives of our pilot investigation are to develop optimal methods to characterize the primary endpoint of the study-knee pain, and to gather preliminary data on genetic markers in the human genome that are associated with a certain pain phenotype. The specific issues for this study will be to carry out a preliminary gene association analysis of acute perioperative pain in individuals undergoing total knee replacement and to define a pain phenotype that is composed of multidimensional domains such as opioid consumption, inflammatory markers, anxiety level, degree of catastrophizing, etc. This pain phenotype has to be sensitive enough to pick up changes in pain experience that can be attributed to single nucleotide polymorphisms.
Peripheral nerve blocks are the standard of care for pain management after hip replacement surgery at UPMC Shadyside. This prospective, randomized study is intended to assess the effect of 0.1 versus 0.2% ropivacaine in lumbar plexus nerve catheter infusions after total hip arthroplasty. Ropivacaine peripheral nerve block infusions have been utilized as the standard of care at UPMC Shadyside for many years. Ropivacaine, a less potent left-isomer of bupivacaine, is often used in place of bupivacaine due to less motor blockade and less severe cardiovascular and central nervous system potential toxicity. The primary goal of this study to examine the effect of a low concentration infusion of ropivacaine (0.1%) on postoperative analgesia (evaluated by opioid consumption after 36 hours) compared with the standard accepted concentration of 0.2% ropivacaine in lumbar plexus catheters after primary total hip arthroplasty. Secondary goals are to examine motor function, VAS scores and patient satisfaction with pain control in low concentration 0.1% ropivacaine compared with 0.2% ropivacaine lumbar plexus infusions upto 36 hours after primary total hip arthroplasty.
Chronic Pain is a wellknown complication after cholecystectomy. Intensity of the pain in the first week after the operation is a predictive factor for the development of chronic pain, but it is unknown whether the risk is more related to one of the different components of acute pain (ie somatic, visceral, referred). Furthermore the chronic pain has not been systematically described in terms of type of pain or sensory abnormalities etc. (allodynia, hyperalgesia etc.). The purpose of the study is to examine whether intensity of components of acute pain is predictive for development of chronic pain after cholecystectomy and to characterize the chronic pain by quantitative sensory testing. DNA-samples are collected to examine genetical factors, important for perception of pain, and the development of chronic pain.
The investigators postulate that the use of pre-incisional peritonsillar infiltration of tramadol or lidocaine reduces both the inflammatory response and postoperative analgesic consumption, without harmful effects. Therefore, the present study is designed to evaluate the effects of infiltration of tramadol or lidocaine on the postoperative acute-phase serum protein, C-reactive protein, and analgesic consumption after tonsillectomy.
This study aims to test validity, reliability and practicality of translated NCS, CNPI and FLACC in unconscious patients in 48 hour following craniotomy.
The primary aim of this randomized, double-blind study is to examine the effect of a single intraoperative dose of methadone on analgesic requirements during the first three days after hepatobiliary or foregut surgery. These patients will be compared to subjects receiving a standard dose of the "traditional" intraoperative opioid (hydromorphone). Secondary outcome measures to be assessed will include postoperative pain scores and standard recovery variables such as hospital length of stay.
This study is being done to determine if a drug called gabapentin helps in the postoperative management of patients undergoing hip and knee operations. The investigators wish to determine the effect of gabapentin on pain and sleep following surgery. If we can lessen a patient's pain and improve sleep, the patient will be better able to participate in their physical therapy. Gabapentin has already been shown to lessen postoperative pain when given before surgery. In healthy patients, it has also been shown to improve certain aspects of sleep. We hope to identify the effect of the drug, when given after surgery, on patients' pain and sleep.
