Hypotensive anesthesia is utilized to reduce bleeding during orthopedic surgery. One of the various drugs that have been used to reduce blood pressure is remifentanil. This study was an attempt to compare the effect of remifentanil with that of electroacupuncture (EA) at DU20 on reducing blood pressure. In this randomized controlled clinical trial, 54 patients undergoing lumbar laminectomy were allocated to two groups. Hypotensive anesthesia was performed through infusion of remifentanil 100 μg/kg/min for the control group, and EA at DU20 acupoint with a frequency of 2-10 Hz and intensity of 1-5 mA for the intervention group...

Hypotension commonly occurs in parturients undergoing cesarean delivery under spinal anesthesia. This leads to maternal and neonatal adverse outcomes, including maternal nausea and vomiting and fetal acidosis, and might even lead to cardiovascular collapse if not treated. Arterial dilatation and reduction in systemic vascular resistance are the major contributors to spinal-induced hypotension. Therefore, strategies aimed at expanding the intravascular volume with fluid loading or increasing venous return with lower extremities mechanical compression and lateral tilt have had limited effectiveness in the management of spinal-induced hypotension...

The 21st century has been billed as the era of "precision/personalized medicine." Genetic investigation of clinical syndromes may guide therapy as well as reveal previously unknown biological or pharmacological pathways that may result in novel drug therapies. Several clinical issues in obstetrics and obstetric anesthesiology have been targets for genetic investigations. These include evaluation of the genetic effects on preterm labor and the progression of labor, spinal anesthesia-induced hypotension and the response to medications used to treat hypotension, and the effect of gene variants on pain and analgesic responses...

OBJECTIVE: Some patients experience severe chronic pain after intramedullary spinal cord tumor (IMSCT) resection, but the underlying mechanisms have yet to be fully elucidated. We aimed to investigate perioperative factors associated with chronic pain after IMSCT resection. MATERIALS AND METHODS: We analyzed data from a postal survey and the medical records of patients who had undergone IMSCT resection in our institution between 2000 and 2008. Chronic pain was assessed using the Neuropathic Pain Symptom Inventory score, and its associations with factors related to tumor pathology, patient demographics, neurological findings, surgery, anesthesia, and perioperative management were determined...

BACKGROUND: True IgE-mediated hypersensitivity to opioids is rare and many reactions are due to direct mast cell degranulation. Opioid drug provocation testing (DPT) is the gold standard for diagnosis but is underutilized. OBJECTIVE: The objective of this study was to evaluate the clinical characteristics and predictors of opioid hypersensitivity, as well as outcomes of opioid DPT. METHODS: Patients referred for opioid DPT over the past 9 years were studied...

BACKGROUND AND OBJECTIVES: The quadratus lumborum block was initially described in 2007 and aims at blocking the same nerves as the ones involved on the Transverse Abdominis Plane block, while accomplishing some visceral enervation as well due to closer proximity with the neuroaxis and sympathetic trunk. Given its versatility, we have successfully used it in a wide range of procedures. We report two cases where we believe the dispersion of local anesthetic is likely to have led to a previously undescribed complication...

INTRODUCTION: Shivering, a common intraoperative problem under spinal anesthesia increases the oxygen consumption considerably and is uncomfortable and distressing to the patient, anesthesiologist as well as surgeon. The present study was designed to explore the effectiveness of tramadol, clonidine and dexmedetomidine in the treatment of post spinal anesthesia shivering and to look for their adverse effects. METHODS: This prospective, randomized, double blinded control study was done on 90 patients who developed shivering under spinal anesthesia...

INTRODUCTION: During general anesthesia, arterial hypotension is frequent and may be an important contributor to perioperative morbidity. We assessed the effect of a 5 μg bolus of Norepinephrine (NA) when compared with 50 μg bolus of Phenylephrine (PE) administered to treat hypotension during maintenance anesthesia, on MAP, derived cardiac output and arterial stiffness parameters. METHODS: Patients scheduled for a neurosurgical procedure under general anesthesia were prospectively included...

BACKGROUND: Various types of lumbar dural punctures may contribute to neurological injury. The etiologies of dural injury include; inadvertent dural punctures due to epidurals placed for labor anesthesia, epidural steroid injections (ESI/transforaminal TESI; approximately 9 million ESI performed in the US per year), deliberate placement of intradural pain devices, and spontaneous cerebrospinal fluid (CSF) fistulas. Resulting neurological complications may include; spinal headaches/intracranial hypotension, subdural hematomas, and 6(th) nerve cranial palsies...

BACKGROUND: Thoracic epidural analgesia (TEA) combined with general anesthesia decreases anesthetic requirements by half when hemodynamic criteria are used for the titration of analgesia. We therefore determined the impact of TEA on anesthetic requirements, when a closed-loop controller was used allowing the automated coadministration of propofol-remifentanil guided solely by the Bispectral index. METHODS: This single-center double-blind study enrolled patients scheduled for elective posterolateral thoracotomy using TEA...

BACKGROUND: To meet the need for essential surgery across rural Nepal, anesthesia at district level is delivered by nondoctor anesthetists. They require support to maintain confidence and competence, and upgraded professional registration to secure their status. To meet these needs, a distance-blended learning course was pioneered and delivered. A core course requirement was to log all clinical cases; these were logged on a new e-logbook. METHODS: Fourteen nondoctor anesthesia providers working in 12 different districts across Nepal were enrolled in the 1-year course...

BACKGROUND: The General Anesthesia compared to Spinal anesthesia (GAS) study is a prospective randomized, controlled, multisite, trial designed to assess the influence of general anesthesia (GA) on neurodevelopment at 5 years of age. A secondary aim obtained from the blood pressure data of the GAS trial is to compare rates of intraoperative hypotension after anesthesia and to identify risk factors for intraoperative hypotension. METHODS: A total of 722 infants ≤60 weeks postmenstrual age undergoing inguinal herniorrhaphy were randomized to either bupivacaine regional anesthesia (RA) or sevoflurane GA...

Anesthesiologists work to prevent or minimize secondary injury of the nervous system and improve the outcome of medical procedures. To this end, anesthesiologists must have a thorough understanding of pathophysiology and optimize their skills and equipment to make an anesthesia plan. Anesthesiologists should conduct careful physical examinations of patients and consider neuroprotection at preoperative interviews, consider cervical spinal cord movement and compression during airway management, and suggest awake fiberoptic bronchoscope intubation for stable patients and direct laryngoscopy with manual in-line immobilization in emergency situations...

The aim of this study is to determine the range of S-100β levels during functional endoscopic sinus surgery (FESS) when the mean arterial pressure (MAP) was controlled within 60-70 mmHg. After anesthesia induction with propofol and remifentanil, the patient was positioned in the reverse Trendelenburg position and MAP was controlled within 60-70 mmHg during surgery. For the S-100β assay, blood was taken from a radial arterial catheter before (baseline) and at 20 (T 20) and 60 (T 60) min after setting the reverse Trendelenburg position and controlled hypotension, and at 60 (T post60) min after the end of the operation...

The aim of the study was to investigate the effects of ephedrine intrathecal injection on maternal thermodynamics and spinal nerve block in cesarean section. A total of 107 patients undergoing elective cesarean section under combined spinal epidural anesthesia were randomly divided into two groups: group E: Bupivacaine (6 mg) combined with ephedrine (15 mg) and group C: Bupivacaine (6 mg). Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), the incidence of hypotension, hypertension, tachycardia, nausea and vomiting were all recorded...
