STUDY OBJECTIVE To investigate the analgesic efficacy and safety of epidural infusion of clonidine in children undergoing major abdominal surgery. DESIGN Randomized open-label study. SETTING Postoperative anesthetic unit and pediatric ward of a metropolitan hospital. PATIENTS Forty children aged 0 to 3 years undergoing major abdominal surgery. (More)
BACKGROUND Hypotension following spinal anesthesia for Cesarean delivery is common. Fluid loading is recommended to prevent hypotension, but preload is often ineffective. In non-pregnant patients, coloading has been shown to better maintain cardiac output after spinal anesthesia. The purpose of this meta-analysis was to determine whether the timing of the(More)
BACKGROUND AND OBJECTIVES Paroxysmal nocturnal hemoglobinuria (PNH) is a form of acquired hemolytic anemia in which a defect of glycophosphatidylinositol anchor proteins in the cell membrane of bone marrow stem cells leads to activation of the complement system and consequent destruction of defective cells. The characteristics of this disease are an(More)
BACKGROUND AND OBJECTIVES Intrathecal sufentanil provides analgesia comparable to epidural bupivacaine for the first stage of labor. Both epidural local anesthetics and intrathecal opioid reduce some parameters of the neuroendocrine response to labor pain and the reflex release of oxytocin in animals. In humans, epidural local anesthetics only reduce the(More)
BACKGROUND AND OBJECTIVES The present study was developed to evaluate the analgesic effects of the epidural administration of a combination of morphine and clonidine, whose efficacy has been demonstrated in adults, on the consumption of isoflurane and postoperative consumption of analgesics in children. METHODS Twenty-six children scheduled for(More)
BACKGROUND Clinical identification of lumbar spinous processes is inaccurate in most patients. The purpose of this study was to determine the number of patients required to train anesthesiologists in the use of ultrasound imaging to accurately identify the lumbar spinous processes. METHODS In this pilot study, two anesthesiologists studied patients(More)
BACKGROUND AND OBJECTIVES Clonidine is an a2-agonist which decreases intravenous and inhalational anesthetics consumption. This study aimed at evaluating the cost-benefit ratio of preanesthetic medication with intravenous clonidine for general anesthesia with sevoflurane in outpatient procedures. METHODS Forty five patients aged 15 to 52 years were(More)
BACKGROUND AND OBJECTIVES Several anesthetic techniques have been proposed for different pediatric surgeries to promote postoperative analgesia, among other advantages. This study aimed at evaluating propofol infusion rate and postanesthetic recovery of children submitted to upper abdominal surgeries under epidural anesthesia with 0.2% ropivacaine(More)
BACKGROUND AND OBJECTIVES The risk of perioperative anaphylaxis should always be considered. The incidence of anesthetic allergic reactions is controversial, varying from 1/3,000 to 1/20,000, with mortality range between 3 and 9%. This report describes the use of methylene blue as coadjuvant drug to treat anaphylaxis refractory to conventional therapy. (More)
BACKGROUND AND OBJECTIVES Induced arterial hypotension is an effective technique to decrease surgical bleeding. Clonidine is an a2-agonist with central action which was proven to be safe in anesthesia. This study aimed at evaluating the efficacy of intravenous clonidine as the primary drug for induced arterial hypotension. METHODS Participated in this(More)
