Preoperative continuation of aspirin administration in patients undergoing major abdominal malignancy surgery.

J Anesth 2019 Feb 27;33(1):90-95. Epub 2018 Nov 27.

Department of Anesthesiology and Intensive Care Medicine, Kawasaki Medical School, 577 Matsushima, Kurashiki, Okayama, 701-0192, Japan.

Purpose: In contrast to that in a nonoperative setting, it has been shown that perioperative administration of aspirin did not decrease the rate of death or myocardial infarction but increased major bleeding risk. Since these conflicting results might be due to concurrent use of anticoagulants and a lower thrombotic risk of patients, this cohort study was carried out for patients at a high thrombotic risk without concurrent use of anticoagulants.

Methods: Medical records for patients who underwent major abdominal malignancy surgery and who were on a preoperative antiplatelet regimen were reviewed. Read More

Postoperative thoracic and low back pain following endovascular aortic repair associated with stenting location.

J Anesth 2019 Feb 24;33(1):75-79. Epub 2018 Nov 24.

Department of Anesthesiology and Critical Care, Hiroshima University Hospital, Hiroshima, Japan.

Background: We have noted that patients frequently complain of thoracic or low back pain after undergoing an endovascular aortic repair, which we speculated was caused by the indwelling stent.

Methods: We investigated the patients who underwent an elective thoracic or abdominal endovascular aortic repair (TEVAR or EVAR) and noted the location of stent, and postoperative pain. The incidence of either thoracic or low back pain at individual vertebra levels was determined, after which we fitted the sigmoidal function to the discrete data to obtain a cut-off line. Read More

Roles of inflammation, neurogenic inflammation, and neuroinflammation in pain.

J Anesth 2019 Feb 17;33(1):131-139. Epub 2018 Nov 17.

Center for Translational Pain Medicine, Department of Anesthesiology, Duke University Medical Center, 3 Genome CT, MSRB3 Room 6148, Durham, NC, 27710, USA.

Inflammation is the body's response to injury and infection, involving a complex biological response of the somatosensory, immune, autonomic, and vascular systems. Inflammatory mediators such as prostaglandin, proinflammatory cytokines, and chemokines induce pain via direct activation of nociceptors, the primary sensory neurons that detect noxious stimuli. Neurogenic inflammation is triggered by nerve activation and results in neuropeptide release and rapid plasma extravasation and edema, contributing to pain conditions such as headache. Read More

Both Bupivacaine and Levobupivacaine inhibit colon cancer cell growth but not melanoma cells in vitro.

J Anesth 2019 Feb 13;33(1):17-25. Epub 2018 Nov 13.

Anaesthetics, Pain Medicine and Intensive Care, Department of Surgery and Cancer, Faculty of Medicine, Imperial College London, Chelsea and Westminster Hospital, London, SW10 9NH, UK.

Background: Retrospective studies indicate that the use of regional anaesthesia causes a reduction in cancer recurrence after oncological surgery, which could be due to anaesthetic's negating effect on immunosuppression related to the surgical stress response. Local anaesthetics may also exert direct suppressive effects on malignant cells, an area where further investigation is urgently needed.

Methods: Human colon cancer cells and human melanoma cells were cultured and then treated with 1 mM bupivacaine or levobupivacaine for up to 24 or 48 h. Read More

Peak airway pressure is lower during pressure-controlled than during manual facemask ventilation for induction of anesthesia in pediatric patients-a randomized, clinical crossover trial.

J Anesth 2019 Feb 12;33(1):33-39. Epub 2018 Nov 12.

Department of Anesthesiology and Critical Care, Medical Center, University of Freiburg, Freiburg, Germany.

Purpose: Facemask ventilation during the induction of general anesthesia in paediatric patients remains a challenge as it may result in hypoxic conditions and gastric insufflation with subsequent regurgitation and aspiration. So far, it is unclear if pressure-controlled or manual facemask ventilation is preferable in children. We hypothesized that pressure-controlled ventilation in apnoeic children results in lower peak airway pressure and flow rates compared to manual ventilation at comparable respiratory rates and tidal volumes.

Practical guide for the management of systemic toxicity caused by local anesthetics.

Authors:

J Anesth 2019 Feb 11;33(1):1-8. Epub 2018 Nov 11.

Systemic toxicity from local anesthetics can occur in any of the wide range of situations in which these agents are used. This practical guide is created to generate a shared awareness of the prevention, diagnosis, and treatment of local anesthetic systemic toxicity among all medical professionals who perform nerve blocks. Systemic toxicity of local anesthetic is induced by an increase of its protein-unbound plasma concentration. Read More

Local anesthetic spread into the paravertebral space with two types of quadratus lumborum blocks: a crossover volunteer study.

J Anesth 2019 Feb 9;33(1):26-32. Epub 2018 Nov 9.

Department of Anesthesiology, Nagoya University Graduate School of Medicine, 65 Tsurumai-cho, Showa-Ku, Nagoya, 466-8550, Japan.

Purpose: Previous work showed that 20 mL of local anesthetic (LA) did not spread into the paravertebral space (PVS) via the intramuscular quadratus lumborum block (QLBi). If spread of LA into the PVS can be achieved by increasing the total LA volume, QLBi can be more effective. We hypothesized that a larger volume of LA for the QLBi would spread into the PVS.

Association between intraoperative phenylephrine administration and umbilical artery pH in women with hypertensive disorders of pregnancy: a retrospective cohort study.

J Anesth 2018 Dec 30;32(6):893-900. Epub 2018 Oct 30.

Department of Anesthesiology and Pain Medicine, Hyogo College of Medicine, Mukogawa-cho 1-1, Nishinomiya, Hyogo, 663-8501, Japan.

Purpose: In healthy pregnant women undergoing Cesarean section, treatment of post-spinal hypotension (PSH) with phenylephrine is reportedly more efficacious than ephedrine in preventing a decline in umbilical artery pH (UApH), which is an indicator of fetal acidosis. However, phenylephrine has the potential to reduce placental blood flow and consequently decrease UApH in women who develop hypertensive disorders of pregnancy (HDP), due to decreased cardiac function and placental vascular abnormalities. We aimed to verify the association between decreased UApH and phenylephrine administered before delivery to treat PSH in women with HDP. Read More

High-dose intraoperative remifentanil infusion increases early postoperative analgesic consumption: a prospective, randomized, double-blind controlled study.

J Anesth 2018 Dec 29;32(6):886-892. Epub 2018 Oct 29.

Department of Anesthesiology and Pain Medicine, Chonbuk National University Hospital, Geonji-ro 20, Jeonju, 54907, Republic of Korea.

Purpose: The purpose of this study was to determine whether intraoperative infusion of remifentanil induces acute tolerance to opioids, and compare the postoperative pain and opioid consumption by the effect site concentrations of remifentanil.

Methods: One hundred and ninety-eight patients undergoing gastrectomy were randomly assigned to maintain target effect site concentrations of remifentanil at 0 (Group 1, n = 39), 2 (Group 2, n = 40), 4 (Group 3, n = 39), 8 (Group 4, n = 40), or 12 ng/ml (Group 5, n = 40) during operation. Postoperative pain intensities and fentanyl requirement were recorded at postoperative 2, 6, 24, and 48 h. Read More

Dexmedetomidine preserves the endothelial glycocalyx and improves survival in a rat heatstroke model.

J Anesth 2018 Dec 29;32(6):880-885. Epub 2018 Oct 29.

Department of Anesthesiology and Intensive Care, Hamamatsu University School of Medicine, 1-20-1 Handayama, Higashi-ku, Hamamatsu, Shizuoka, 431-3192, Japan.

Purpose: Heatstroke causes systemic inflammation, followed by vascular endothelial damage. The normal vascular endothelium is coated by endothelial glycocalyx (EGCX). Dexmedetomidine (DEX) has an anti-inflammatory effect, but there has been little investigation on the influence of heatstroke on EGCX and the effect of DEX on this condition. Read More

The relationship between seizure in electroconvulsive therapy and pupillary response using an automated pupilometer.

J Anesth 2018 Dec 16;32(6):866-871. Epub 2018 Oct 16.

Department of Anesthesiology and Critical Care Medicine, Kyushu University Graduate School of Medicine, Fukuoka, Japan.

Objectives: Seizure duration and morphology, postictal suppression, and sympathetic nervous system activation are all recommended as assessments of adequate seizure in electroconvulsive therapy (ECT). However, blood pressure and heart rate are not typically assessed as part of sympathetic nervous system activation because of the administration of anesthetic or cardiovascular agents during ECT. Although the pupils are known to reflect to the activity of autonomic nervous system and the degree of brain damage, previous studies have not examined the relationship between seizure of electroconvulsive therapy and pupillary response.

Heated humidified high-flow nasal oxygen prevents intraoperative body temperature decrease in non-intubated thoracoscopy.

J Anesth 2018 Dec 15;32(6):872-879. Epub 2018 Oct 15.

Department of Anesthesiology, National Taiwan University Hospital, National Taiwan University College of Medicine, Jen-Ai Road, Section 1, Taipei, 10051, Taiwan, Republic of China.

Purpose: In patients receiving non-intubated video-assisted thoracic surgery (NIVATS), transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) has been applied instead of oxygen mask for better oxygenation. However, the THRIVE effects on intraoperative temperature decrease have not been investigated.

Methods: Pre- and postoperative temperatures, measured by an infrared tympanic ear thermometer, taken before sending patients to the operation room and immediately upon their arrival in the postoperative anesthesia unit, were collected from medical records of patients who received NIVATS either with oxygen mask or THRIVE.

How neuraxial labor analgesia differs by approach: dural puncture epidural as a novel option.

J Anesth 2019 Feb 6;33(1):125-130. Epub 2018 Oct 6.

Department of Anesthesiology and Reanimation, Gazi University School of Medicine, Besevler, 06500, Ankara, Turkey.

Background And Aim: Neuraxial analgesia techniques are not limited to just standard epidural and CSE blocks. A novel approach called dural puncture epidural (DPE) which is a modification of CSE in terms of practice has gained popularity after its description and use in the obstetric population.  The aim of this review is to address the practice of DPE technique as a novel option by reviewing its benefits as well as side and/or adverse effects and to understand how neuraxial labor analgesia differs by approach based on the information available in the current literature DISCUSSION: Despite controversies and concerns, more rapid onset of analgesia, early bilateral sacral analgesia, lower incidence of asymmetric block and fewer maternal and fetal side effects are provided with DPE when compared to epidural.
