Combining Stellate ganglion block and intravenous regional anesthesia to treat complex regional pain syndrome: A 19-years' experience in a tertiary center.

Objectives: To study reduction in pain score after treatment with intravenous regional anesthesia (IVRA) and Stellate ganglion block (SGB) combination on complex regional pain syndrome (CPRS) patients and to quantify patients' satisfaction with treatment and occurrence of complications.

Methods: This is a record-based retrospective review carried out in 2020, targeting patients treated in the University of Jordan Hospital, Amman, Jordan, over the years 2002-2020.

Results: Among 99 patients, a significant drop in pain scores occurred in 88% of the patients' sample.

Remifentanil consumption in septoplasty surgery under general anesthesia. Association with humane mu-opioid receptor gene variants.

To evaluate the influence of the ORM1 variants in codon 118 on the intra-operative remifentanil consumption under general anesthesia. Methods: A prospective gene association study, performed at the Jordan University Jordan, Amman, Jordan from September 2013 to August 2014. It includes patients who underwent septoplasty surgery under general anesthesia.

Comparison of caudal bupivacaine alone with bupivacaine plus two doses of dexmedetomidine for postoperative analgesia in pediatric patients undergoing infra-umbilical surgery: a randomized controlled double-blinded study.

Background: Data are still insufficient about the effects of different concentrations of caudal dexmedetomidine when used to prolong postoperative analgesia in children. The aim of this study was to assess the analgesic efficacy and side effects of two doses of caudal dexmedetomidine (1 and 2 μg·kg(-1)) co-administered with bupivacaine in terms of postoperative pain scores and requirement of postoperative analgesia over 24 h in children undergoing infra-umbilical surgery.

Methods: Ninety-one children, aged 1-6 years, undergoing infra-umbilical surgery were included and randomly allocated into three groups of caudal block.

Horner's syndrome after lumbar epidural analgesia during labor.

Horner's syndrome is rarely reported after epidural analgesia during labor. The use of Top-Up local anesthetic for controlling labor pain in the first stage of labor, or to dense the block in caesarean deliveries can result in this complication. We reported a cases of Horner's syndrome during epidural analgesia in labor in spite of not giving any Top-Up dose.

The impact of long-lasting preemptive epidural analgesia before total hip replacement on the hormonal stress response. A prospective, randomized, double-blind study.

Unlabelled: Recent studies suggest that preemptive analgesia may be effective in reducing postoperative pain. One physiologic explanation may be interference with the endogenous opioid response. We investigated whether long-lasting preoperative preemptive analgesia may have an effect on the hormonal stress response after total hip replacement.

The effect of low serum bicarbonate values on the onset of action of local anesthesia with vertical infraclavicular brachial plexus block in patients with end-stage renal failure.

Vertical infraclavicular brachial plexus block is utilized in patients with chronic renal failure at the time of creation of an arterio-venous fistula (AVF). The aim of this study is to test the effect of impaired renal function, with the resulting deranged serum electrolytes and blood gases, on the success rate and the onset of action of the local anesthetics used. In this prospective clinical study, we investigated the effect of the serum levels of sodium, potassium, urea, creatinine, pH, and bicarbonate on the onset of action of a mixture of lidocaine and bupivacaine administered to create infraclavicular brachial plexus block.

Intraoperative administration of dexmedetomidine reduces the analgesic requirements for children undergoing hypospadius surgery.

Background: The present study was designed to assess whether an intraoperative administration of dexmedetomidine would decrease the intraoperative and postoperative analgesic requirements for paediatric patients undergoing hypospadius surgery.

Methods: Forty-eight children (American Society of Anesthesiologists-1) aged 1-12 years undergoing hypospadius repair under general anaesthesia were randomly assigned into dexmedetomidine or placebo groups, D and P, respectively. Group D received a loading dose of dexmedetomidine 1 microg kg(-1) after induction of anaesthesia, followed by a continuous infusion at a rate of 0.

A balanced anesthesia with dexmedetomidine decreases postoperative nausea and vomiting after laparoscopic surgery.

Objective: To evaluate the effect of adding dexmedetomidine to a balanced anesthetic technique on postoperative nausea and vomiting after laparoscopic gynecological surgeries.

Methods: A prospective double-blind randomized study was designed at Jordan University Hospital, Amman, Jordan between December 2008 and February 2009. Eighty-one female patients in their child-bearing age (17-48 years); American Society of Anesthesiologists (ASA) clinical status I, who were scheduled for elective diagnostic laparoscopic surgeries under general anesthesia were divided into 2 groups.

Intravenous dexmedetomidine prolongs bupivacaine spinal analgesia.

Background: The prolongation of spinal anesthesia by using clonidine through the oral, intravenous and spinal route has been known. The new alpha 2 agonist, dexmedetomidine has been proved to prolong the spinal anesthesia through the intrathecal route. We hypothesized that dexmedetomidine when administered intravenously following spinal block, also prolongs spinal analgesia.

Effect of dexmedetomidine added to spinal bupivacaine for urological procedures.

Objectives: To determine the effect of adding dexmedetomidine to bupivacaine for neuraxial anesthesia.

Methods: Sixty-six patients were studied between April and May 2008 in the University of Jordan, Amman Jordan. They were randomly assigned into 3 groups, each receiving spinal bupivacaine 12.
