Published Studies Related to Demerol (Meperidine)

Meperidine relieves pain during transrectal ultrasound-guided prostate biopsy. [2014]
ultrasound-guided prostate biopsy... CONCLUSION: Intramuscular meperidine injection is a safe and effective analgesic

Intra-articular bupivacaine reduces postoperative pain and meperidine use after total hip arthroplasty: a randomized, double-blind study. [2014]
One hundred patients receiving unilateral total hip arthroplasty (THA) were randomized to receive an intra-articular injection of 300mg bupivacaine or normal saline after completion of surgery. Pain scores of the bupivacaine group were significantly lower than those of the control group the first 12hours postoperatively (all, P<0.001).

Comparison of the analgesic efficacy of dexketoprofen trometamol and meperidine HCl in the relief of renal colic. [2014]
In this study, the analgesic effects of dexketoprofen trometamol and meperidine hydrochloride were compared in patients diagnosed with renal colic. This study was a prospective, randomized, double-blind study... With this study, we concluded that dexketoprofen trometamol, from the nonsteroidal anti-inflammatory drug group, can be within the primary treatment options for renal colic because of better analgesic efficacy, being well tolerated by patients compared with meperidine hydrochloride.

Antishivering effects of two different doses of intrathecal meperidine in caesarean section: a prospective randomised blinded study. [2011.03]
BACKGROUND AND OBJECTIVE: Shivering causes various adverse disturbances and interferes with monitoring. The optimal dose of intrathecal meperidine to prevent shivering without producing other side-effects remains unknown. This prospective randomised double-blinded study was conducted to compare the antishivering effects of two different doses of intrathecal meperidine... CONCLUSION: The use of intrathecal meperidine for caesarean section during spinal anaesthesia for the prevention of shivering cannot be recommended as its use is associated with increased incidence of nausea and vomiting.

Clinical Trials Related to Demerol (Meperidine)

Remifentanil Only vs. Midazolam and Meperidine During Elective Colonoscopy [Completed]

A Comparison of Meperidine for Post-Cesarean Analgesia: Bolus Versus Infusion and Bolus [Not yet recruiting]
The purpose of this study is to determine if epidural meperidine administered by patient-controlled bolus button is equivalent to a low dose infusion plus patient-controlled bolus.

Efficacy and Safety Profiles of Combination Sedation Propofol With Midazolam and Meperidine. [Completed]
The purpose of this study is to compare efficacy and safety of combination of propofol and midazolam with meperidine versus midazolam and meperidine for ambulatory ERCP

Neuraxial Pethidine After Lumbar Surgery Trial [Recruiting]
The hypothesis is that epidural pethidine is an effective form of pain relief following lumbar spinal surgery, resulting in significantly lower usage of concomitantly administered (intravenous) patient-controlled analgesia (PCA) pethidine.

Study of the Effectiveness of Administration of Meperidine on the Length of Active Phase of Labor in Women [Recruiting]
Labor pain is universal and occurs acutely. This is the most painful experience in a woman's life. Pain relief during labor is expected to have positive impact on the progress, outcome and cost of labor. However, it is controversial whether labor analgesia shortens the length of labor and influences progression to cesarean. Labor analgesia can be performed via spinal, epidural or systemic routes (intravenous or intramuscular). Opioid agonists (meperidine, fentanyl etc.) as well are the systemic agents frequently used for labor analgesia. Results of the studies concerning effect of meperidine on the length of labor are controversial. Many studies have expressed that meperidine has no effect or effect on the progress of labor. This study aims to evaluate the effect of meperidine on the length of active phase of labor in nulliparous or multiparous women, who will be randomized into case and control groups.
