Facemask wearing does not impact neuro-electrical brain activity.

Given the massive use of facemasks (FMs) during the covid-19 pandemic, concerns have been raised regarding the effect of FMs wearing on overall health. This study aimed at evaluating the effect of surgical FM on brain neuro-electrical activity. Electroencephalography (EEG) background frequency (BGF) and background amplitude (BGA) was performed on 30 volunteers before (baseline), during and after wearing a FM for 60 min.

A Co-Induction Technique Utilizing 4% Sevoflurane Followed by 0.75 mg/kg Propofol in Elderly Patients Undergoing Minimally Invasive Procedures: A Prospective Randomized Control Study.

Elderly patients constitute a large segment of healthcare receivers. Considering the functional deterioration of multiple organ systems with aging, achieving a safe perioperative approach is challenging. Our aim is to study the safety and effectiveness of a genuinely regimented co-induction technique in order to minimize anesthesia-related complications.

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.

Short thyromental distance is a surrogate for inadequate head extension, rather than small submandibular space, when indicating possible difficult direct laryngoscopy.

Context: Airway research in anaesthesia shows that the thyromental distance (TMD) as a predictor of difficult intubation is subject to variable sensitivity and specificity. Recently, its value in this regard has been questioned with calls for a redefinition of its role.

Objective(s): To define the role of TMD as a predictor of possible difficult laryngoscopy.

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.

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.

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.

Effects of sevoflurane on postoperative liver functions in morbidly obese as compared to the non-obese patients.

Objective: To assess the effect of sevoflurane anesthesia on hepatic function in morbidly obese versus non-obese patients undergoing abdominal surgeries.

Methods: We prospectively evaluated the levels of the serum concentration of liver enzymes aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), gamma glutamyl transferase (GGT), alkaline phosphatase (ALP), and total bilirubin (TBil), in 42 morbidly obese and 40 non obese patients who were scheduled for elective abdominal surgery under sevoflurane anesthesia at the Jordan University Hospital, Amman, Jordan. Measurement of liver enzymes was done in the recovery room, and on the first, 3 and 7 days after sevoflurane anesthesia, and the results were compared between the morbidly obese and non obese patients.

Anesthesia and electrocorticography for epilepsy surgery: a Jordanian experience.

Objective: Electrocorticography (ECoG) may be used to guide epilepsy surgery. However, anesthetics can suppress epileptiform activity or induce confounding burst-suppression patterns and the relationship between ECoG results and seizure outcome is controversial. In this study, we evaluated the ECoG activity under several different anesthetics and examined the relationship between ECoG and outcome.

Duration of venous occlusion with lidocaine for preventing propofol induced pain.

Objective: To study the effect of the venous occlusion duration using lidocaine on the incidence and severity of propofol induced pain.

Methods: A prospective double-blind randomized study was designed at Jordan University Hospital, Amman, Jordan between October 2007 and November 2007. One hundred and fifty patients aged 14-70 years, American Society of Anesthesiologists (ASA) clinical status I and II who underwent elective surgeries under general anesthesia, were divided into 3 groups.
