IMPORTANCE Continuous morphine infusion as standard postoperative analgesic therapy in young infants is associated with unwanted adverse effects such as respiratory depression. OBJECTIVE To determine whether intravenous paracetamol (acetaminophen) would significantly (>30%) reduce morphine requirements in neonates and infants after major surgery. DESIGN, SETTING, AND PATIENTS Single-center,...

Cholinergic circuitry and muscarinic receptors within the spinal cord have been proposed to contribute to the analgesic effects of systemic morphine. In this study, we determined whether the descending pathways are involved in the inhibitory effect of systemic morphine on dorsal horn projection neurons mediated by activation of the spinal cholinergic system. Single-unit activity of dorsal horn ...

Background: Ultra-fast track anesthesia (UFTA) aims at immediate extubation of cardiac surgical patients at the end of the operation. It has not been found to increase postoperative cardiorespiratory morbidity, sympathoadrenal stress, or mortality. On the other hand, it significantly reduces costs and improves resource utilization. Methods: Fifty two consecutive patients underwent open heart su...

BACKGROUND Most patients undergoing outpatient surgeries have the unpleasant experience of high level pain after surgery. Compared with open surgeries, arthroscopic procedures are less painful; however, inadequate pain management could be associated with significant concerns. Opioids alone or in combination with local anesthetics are frequently used for diminishing postoperative pain using intr...

backround: we aimed to evaluate analgesic efficacy, opioid-sparing, and opioid-related adverse effects of intravenous paracetamol and intravenous dexketoprofen trometamol in combination with iv morphine after total abdominal hysterectomy. materials and methods: sixty american society of anesthesiologist physical status classification i-ii patients scheduled for total abdominal hysterectomy were...

Objective. This pilot study clinically tests whether a conversion factor of 2 to 1 is appropriate when changing from oral to parenteral morphine administration in the treatment of cancer-related nociceptive pain and calculates the size of an adequately powered future study. Methods. Eleven outpatients with incurable cancer and well-controlled nociceptive pain were randomly assigned to either in...

introduction: ghrelin increases growth hormone secretion and food intake. growth hormone (gh), steroid hormones and opioids are involved in the regulation of food intake. so, they may have a role in the regulation of ghrelin secretion. we determined the effect of intravenous injections of progesterone, gh and morphine or co-administration of these hormones on ghrelin concentration and body weig...

BACKGROUND AND OBJECTIVES Patients undergoing thoracotomy experience severe postoperative pain. This study aimed at evaluating postoperative analgesia with the association of intravenous and epidural morphine as compared to a single route. METHODS Participated in this study 20 patients of both genders, physical status ASA I, II or III, scheduled for thoracotomy. Patients were premedicated wit...
