Comparison of Intra- and postoperative effectiveness of erector spinae plane block and patient controlled analgesia in patients undergoing coronary artery bypass grafting surgery.

The aim of our study was to compare bilateral erector spinae plane block (ESPB) efficacy on pain management with patient controlled analgesia (PCA) during the perioperative period in patients scheduled for coronary artery bypass grafting (CABG). After ethics committee approval (2019-7/31 dated 09.04.

The effects of the Trendelenburg position and the Valsalva manoeuvre on internal jugular vein diameter and placement in children.

Introduction: We compared the effects of various surgical positions, with and without the Valsalva manoeuvre, on the diameter of the right internal jugular vein (RIJV).

Methods: We recruited 100 American Society of Anesthesiologists physical status class I patients aged 2-12 years. The patients' heart rate, blood pressure, peripheral oxygen saturation and end-tidal CO2 pressure were monitored.

Do metoclopramide and ondansetrone alter mivacurium-induced neuromuscular blockade? - a randomised trial.

Background: We aimed to investigate the effects of metoclopramide and ondansetrone on mivacurium neuromuscular blockade.

Methods: Seventy five, ASA I-II patients, aged 18-65 and scheduled for elective surgery requiring tracheal intubation were included in the study. The patients received metoclopramide 10 mg, ondansetrone 4 mg or normal saline 5 mL; group M, group O, group NS (n=25), respectively.

Thoracic paravertebral block for video-assisted thoracoscopic surgery: single injection versus multiple injections.

Objective: Thoracic paravertebral blocks (PVBs) have been shown to be effective for analgesia after video-assisted thoracoscopic surgery (VATS) with single- and multiple-injection techniques. The efficacy of single-injection PVB was compared with multiple-injection PVB on postoperative analgesia in VATS was studied.

Design: Prospective, randomized study.

Comparison of two different doses of intrathecal levobupivacaine for transurethral endoscopic surgery.

Objective: To evaluate the effects of two different spinal isobaric levobupivacaine doses on spinal anesthesia characteristics and to find the minimum effective dose for surgery in patients undergoing transurethral resection (TUR) surgery.

Materials And Methods: Fifty male patients undergoing TUR surgery were included in the study and were randomized into two equal groups: Group LB10 (n=25): 10 mg 0.5% isobaric levobupivacaine (2 ml) and Group LB15 (n=25): 15 mg 0.

Induction of anesthesia in coronary artery bypass graft surgery: the hemodynamic and analgesic effects of ketamine.

Objective: The aim of this prospective, randomized study was to evaluate the hemodynamic and analgesic effects of ketamine by comparing it with propofol starting at the induction of anesthesia until the end of sternotomy in patients undergoing coronary artery bypass grafting surgery.

Introduction: Anesthetic induction and maintenance may induce myocardial ischemia in patients with coronary artery disease. A primary goal in the anesthesia of patients undergoing coronary artery bypass grafting surgery is both the attenuation of sympathetic responses to noxious stimuli and the prevention of hypotension.

Intravenous dexmedetomidine, but not midazolam, prolongs bupivacaine spinal anesthesia.

Purpose: Midazolam has only sedative properties. However, dexmedetomidine has both analgesic and sedative properties that may prolong the duration of sensory and motor block obtained with spinal anesthesia. This study was designed to compare intravenous dexmedetomidine with midazolam and placebo on spinal block duration, analgesia, and sedation in patients undergoing transurethral resection of the prostate.

Preoperative multiple-injection thoracic paravertebral blocks reduce postoperative pain and analgesic requirements after video-assisted thoracic surgery.

Objective: The hypothesis was tested that preoperative multiple-injection thoracic paravertebral blocks reduce opioid requirements and promote early ambulation after video-assisted thoracic surgery procedures.

Design: Prospective, randomized, controlled, blinded study.

Setting: Single-university hospital.

Intraoperative infusion of dexmedetomidine reduces perioperative analgesic requirements.

Purpose: This prospective, randomized, double-blind study was designed to assess whether intraoperative infusion of dexmedetomidine provides effective postoperative analgesia. Postoperative pain scores and morphine consumption were compared in a treated group and a placebo group, both of which received patient-controlled morphine after total abdominal hysterectomy.

Methods: Fifty women were randomly assigned to two groups.

A comparison of effects of alfentanil, fentanyl, and remifentanil on hemodynamic and respiratory parameters during stereotactic brain biopsy.

The aim of this study was to compare the effects of 3 different sedative-analgesic regimens in patients with intracranial mass lesions undergoing stereotactic brain biopsy. A 135 outpatients with American Society of Anesthesiologists I to II were divided into 3 groups: group A (n = 45) received a loading dose of IV alfentanil 7.5 microg/kg followed by infusion rate of 0.

Elevation of serum cerebral injury markers correlates with serum choline decline after coronary artery bypass grafting surgery.

The aims of this study were to determine circulating choline status and its relationship to circulating levels of S-100beta protein and neuron-specific enolase, biochemical markers of cerebral injury and cognitive decline, after coronary artery bypass grafting (CABG) surgery. Preoperatively, patients scheduled for off-pump or on-pump CABG surgery had serum concentrations of 12.0+/-0.

Spinal anesthesia in a patient with severe thoracolumbar kyphoscoliosis.

Patients with spine abnormalities, present unique challenges to the health care provider responsible for administrating sedation and anesthesia during surgical and technical procedures. Spinal deformities may cause difficulties with both tracheal intubation and regional anesthesia. This report describes the anesthetic management for two urological operations that were performed in a patient with extremely severe thoracolumbar kyphoscoliosis.

A new technique for superior hypogastric plexus block: the posteromedian transdiscal approach.

Superior hypogastric plexus block has been advocated for the treatment of cancer related pelvic pain. Neurolysis is usually established using the classical posterolateral approach in the prone position, in which correct placement of the needle is sometimes difficult due to vertebral anatomy and the patient's inability to lie prone. We describe an alternative posteromedian transdiscal approach under fluoroscopic guidance for the treatment of intractable pelvic pain in three patients, in whom the classical approach was not possible.

Effects of ketamine and thiopental on ischemia reoxygenation-induced LDH leakage and amino acid release from rat striatal slices.

Increased release of glutamate is thought to contribute to ischemia-induced neuronal damage. Since general anesthetics such as thiopental and ketamine are thought to provide some degree of cerebral protection, this study was intended to 1) compare the effectiveness of ketamine and thiopental on ischemia-induced tissue damage; and, if so, 2) determine whether attenuation of the increased amino acid release is the sole mechanism for the protective effects demonstrated. Striatal slices prepared from Wistar Albino rats were incubated in an ischemic medium for 1 hour followed by 5 hours in a reoxygenation (REO) medium.

[Blockade of ganglion impar through sacrococcygeal junction for cancer-related pelvic pain].

Impar ganglion block provides pain relief in patients who suffer from sympathetically mediated pain arising from disorders of viscera and somatic structures within the pelvis and perineum. We performed impar ganglion blockade through sacrococcygeal junction instead of anococcygeal ligament in 9 patients who had localized perineal pain of visceral origin. All the blocks which were performed through sacrococcygeal junction without bending the needle under fluoroscopic guidance were easy to perform without any complication.
