Consideraciones anestésicas en emergencias quirúrgicas neonatales
Anaesthetic consideration for neonatal surgical emergencies.
Pani N, Panda CK.
Indian J Anaesth [serial online] 2012 [cited 2013 Mar 9];56:463-9.
A newborn requires constant vigilance, rapid recognition of the events and swift intervention during anaesthesia. The anaesthetic considerations in neonatal surgical emergencies are based on the physiological immaturity of various body systems, poor tolerance of the anaesthetic drugs, associated congenital disorders and considerations regarding the use of high concentration of oxygen. The main goal is for titration of anaesthetics to desired effects, while carefully monitoring of the cardiorespiratory status. The use of regional anaesthesia has shown to be safe and effective. Advancements in neonatology have resulted in the improvement of the survival of the premature and critically ill newborn babies. Most of the disorders previously considered as neonatal surgical emergencies in the past no longer require immediate surgery due to new technology and new methods of treating sick neonates. This article describes the common neonatal surgical emergencies and focuses on factors that affect the anaesthetic management of patients with these disorders.

Abstract
Arthrogryposis multiplex congenita is a rare disease, characterized by non-progressive, multiple joint contractures since birth. Anesthetic issues include difficult intravenous access, difficult airway management and regional anesthesia. We report the anesthetic management of a six-day-old neonate presenting to the emergency with features of intestinal obstruction, who was detected for the first time to have arthrogryposis multiplex congenita. General anesthesia along with caudal analgesia for peroperative and postoperative pain relief was used. There was an episode of intraoperative hyperthermia, which was tackled successfully. The child had an uneventful post-anesthesia recovery.

Estan descritos algunos factores determinantes del PC, como tambien la neuroproteccion proporcionada por los agentes anestésicos y no anestesicos. Contenido: Se hizo la revision con base en los principales articulos de la literatura que engloban la fi siopatologia de la isquemia-reperfusion y la lesion neuronal, y los factores no farmacológicos (infl amacion, glucemia y temperatura), y farmacologicos relacionados con el cambio de la respuesta a la isquemia-reperfusion, ademas de la neuroproteccion inducida por el uso de los anestesicos. Conclusiones: El cerebro tiene la capacidad de protegerse contra la isquemia cuando se le estimula. La elucidación de ese mecanismo posibilita la aplicacion de sustancias inductoras del precondicionamiento cerebral, como algunos anestesicos, otros farmacos y medidas no farmacologicas, como la hipotermia, con el fi n de inducir la tolerancia a las lesiones isquemicas. http://www.scielo.br/pdf/rba/v63n1/es_v63n1a11.pdf  Atentamente Anestesiología y Medicina del Dolor www.anestesia-dolor.org

Diclofenaco prolonga la repolarización del músculo ventricular con daño en la repolarización de reserva  Diclofenac prolongs repolarization in ventricular muscle with impaired repolarization reserve. Kristóf A, Husti Z, Koncz I, Kohajda Z, Szél T, Juhász V, Biliczki P, Jost N, Baczkó I, Papp JG, Varró A, Virág L. Division of Cardiovascular Pharmacology, Hungarian Academy of Sciences, Szeged, Hungary. PLoS One. 2012;7(12):e53255. doi: 10.1371/journal.pone.0053255. Epub 2012 Dec 31. Abstract BACKGROUND: The aim of the present work was to characterize the electrophysiological effects of the non-steroidal anti-inflammatory drug diclofenac and to study the possible proarrhythmic potency of the drug in ventricular muscle. METHODS: Ion currents were recorded using voltage clamp technique in canine single ventricular cells and action potentials were obtained from canine ventricular preparations using microelectrodes. The proarrhythmic potency of the drug was investigated in an anaesthetized rabbit proarrhythmia model. RESULTS: Action potentials were slightly lengthened in ventricular muscle but were shortened in Purkinje fibers by diclofenac (20 µM). The maximum upstroke velocity was decreased in both preparations. Larger repolarization prolongation was observed when repolarization reserve was impaired by previous BaCl(2) application. Diclofenac (3 mg/kg) did not prolong while dofetilide (25 µg/kg) significantly lengthened the QT(c) interval in anaesthetized rabbits. The addition of diclofenac following reduction of repolarization reserve by dofetilide further prolonged QT(c). Diclofenac alone did not induce Torsades de Pointes ventricular tachycardia (TdP) while TdP incidence following dofetilide was 20%. However, the combination of diclofenac and dofetilide significantly increased TdP incidence (62%). In single ventricular cells diclofenac (30 µM) decreased the amplitude of rapid (I(Kr)) and slow (I(Ks)) delayed rectifier currents thereby attenuating repolarization reserve. L-type calcium current (I(Ca)) was slightly diminished, but the transient outward (I(to)) and inward rectifier (I(K1)) potassium currents were not influenced. CONCLUSIONS: Diclofenac at therapeutic concentrations and even at high dose does not prolong repolarization markedly and does not increase the risk of arrhythmia in normal heart. However, high dose diclofenac treatment may lengthen repolarization and enhance proarrhythmic risk in hearts with reduced repolarization reserve. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3534043/pdf/pone.0053255.pdf     Nuevas acciones de los AINES sobre los canales iónicos vasculares: La contabilización de los efectos secundarios cardiovasculares e identificación de nuevas aplicaciones terapéuticas.  Novel Actions of Nonsteroidal Anti-Inflammatory Drugs on Vascular Ion Channels: Accounting for Cardiovascular Side Effects and Identifying New Therapeutic Applications. Brueggemann LI, Mani BK, Mackie AR, Cribbs LL, Byron KL. Department of Molecular Pharmacology and Therapeutics, Loyola University Chicago, Maywood, Illinois. Mol Cell Pharmacol. 2010;2(1):15-19. Abstract Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used medications for the treatment of both acute and chronic pain. Selective cyclooxygenase-2 (COX-2) inhibitors, such as celecoxib (Celebrex(®)), rofecoxib (Vioxx(®)), and diclofenac, have been among the most widely prescribed NSAIDs because they prevent the generation of prostaglandins involved in inflammation and pain, but avoid some of the gastrointestinal complications associated with less selective COX-1/COX-2 inhibitors. In 2004, rofecoxib (Vioxx(®)) was voluntarily withdrawn from the market because of adverse cardiovascular side effects. This led to an explosion of research into the cardiovascular effects of the 'coxibs', which revealed differential cardiovascular risk profiles among the members of this drug class. The differential risk profiles may relate to the tendency of some of the drugs to elevate blood pressure (BP). An important component of BP regulation is dependent on the contractile state of vascular smooth muscle cells (VSMCs), which is controlled to a large extent by the activities of KCNQ (Kv7 family) potassium channels and L-type calcium channels. Our recently published data indicate that celecoxib, but not rofecoxib or diclofenac, at therapeutically relevant concentrations, acts as a Kv7 potassium channel activator and a calcium channel blocker, causing relaxation of VSMCs and decreasing vascular tone. These vasorelaxant ion channel effects may account for the differential cardiovascular risk profiles among the different COX-2 inhibitors. We further speculate that these properties may be exploited for therapeutic benefit in the treatment of cardiovascular diseases or other medical conditions. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2915785/pdf/nihms-184534.pdf  Atentamente Anestesiología y Medicina del Dolor www.anestesia-dolor.org

AINES y riesgo CV/Nonsteroidal anti-inflammatory drugs and CV risk

Riesgo cardiovascular causa-específico asociado con los AINES entre los pacientes con infarto del miocardio. Un estudio a nivel nacional  Cause-specific cardiovascular risk associated with nonsteroidal anti-inflammatory drugs among myocardial infarction patients--a nationwide study. Olsen AM, Fosbøl EL, Lindhardsen J, Andersson C, Folke F, Nielsen MB, Køber L, Hansen PR, Torp-Pedersen C, Gislason GH. Department of Cardiology, Copenhagen University Hospital, Hellerup, Denmark. amschjerning@gmail.com PLoS One. 2013;8(1):e54309. doi: 10.1371/journal.pone.0054309. Epub 2013 Jan 30. Abstract BACKGROUND: Non steroidal anti-inflammatory drugs (NSAIDs) increase mortality and morbidity after myocardial infarction (MI). We examined cause-specific mortality and morbidity associated with NSAIDs in a nationwide cohort of MI patients. METHODS AND RESULTS: By individual-level linkage of nationwide registries of hospitalization and drug dispensing from pharmacies in Denmark, patients aged >30 years admitted with first-time MI during 1997-2009 and their subsequent NSAID use were identified. The risk of three cardiovascular specific endpoints: cardiovascular death, the composite of coronary death and nonfatal MI, and the composite of fatal and nonfatal stroke, associated with NSAID use was analyzed by Cox proportional hazard analyses. Of 97,698 patients included 44.0% received NSAIDs during follow-up. Overall use of NSAIDs was associated with an increased risk of cardiovascular death (hazard ratio [HR] 1.42, 95% confidence interval [CI] 1.36-1.49). In particular use of the nonselective NSAID diclofenac and the selective cyclooxygenase-2 inhibitor rofecoxib was associated with increased risk of cardiovascular death (HR 1.96 [1.79-2.15] and HR1.66 [1.44-1.91], respectively) with a dose dependent increase in risk. Use of ibuprofen was associated with increased risk of cardiovascular death (HR 1.34[1.26-1.44]), whereas naproxen was associated with the lowest risk of (e.g., HR 1.27[1.01-1.59].CONCLUSION: Use of individual NSAIDs is associated with different cause-specific cardiovascular risk and in particular rofecoxib and diclofenac were associated with increased cardiovascular morbidity and mortality. These results support caution with use of all NSAIDs in patients with prior MI. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3559685/pdf/pone. 0054309.pdf     Riesgo cardiovascular con AINES: Revisión sistemática de estudios poblacionales observacionales controlados  Cardiovascular risk with non-steroidal anti-inflammatory drugs: systematic review of population-based controlled observational studies. McGettigan P, Henry D. Hull York Medical School, Hull, United Kingdom. PLoS Med. 2011 Sep;8(9):e1001098. doi: 10.1371/journal.pmed.1001098. Epub 2011 Sep 27. Abstract BACKGROUND: Randomised trials have highlighted the cardiovascular risks of non-steroidal anti-inflammatory drugs (NSAIDs) in high doses and sometimes atypical settings. Here, we provide estimates of the comparative risks with individual NSAIDs at typical doses in community settings. METHODS AND FINDINGS: We performed a systematic review of community-based controlled observational studies. We conducted comprehensive literature searches, extracted adjusted relative risk (RR) estimates, and pooled the estimates for major cardiovascular events associated with use of individual NSAIDs, in different doses, and in populations with low and high background risks of cardiovascular events. We also compared individual drugs in pair-wise (within study) analyses, generating ratios of RRs (RRRs). Thirty case-control studies included 184,946 cardiovascular events, and 21 cohort studies described outcomes in >2.7 million exposed individuals. . CONCLUSIONS: This review suggests that among widely used NSAIDs, naproxen and low-dose ibuprofen are least likely to increase cardiovascular risk. Diclofenac in doses available without prescription elevates risk. The data for etoricoxib were sparse, but in pair-wise comparisons this drug had a significantly higher RR than naproxen or ibuprofen. Indomethacin is an older, rather toxic drug, and the evidence on cardiovascular risk casts doubt on its continued clinical use.

Abstract BACKGROUND: Despite the fact that nonsteroidal anti-inflammatory drugs (NSAIDs) are contraindicated among patients with established cardiovascular disease, many receive NSAID treatment for a short period of time. However, little is known about the association between NSAID treatment duration and risk of cardiovascular disease. We therefore studied the duration of NSAID treatment and cardiovascular risk in a nationwide cohort of patients with prior myocardial infarction (MI). METHODS AND RESULTS: Patients ≥30 years of age who were admitted with first-time MI during 1997 to 2006 and their subsequent NSAID use were identified by individual-level linkage of nationwide registries of hospitalization and drug dispensing from pharmacies in Denmark. Risk of death and recurrent MI according to duration of NSAID treatment was analyzed by multivariable time-stratified Cox proportional-hazard models and by incidence rates per 1000 person-years. Of the 83 677 patients included, 42.3% received NSAIDs during follow-up. There were 35 257 deaths/recurrent MIs. Overall, NSAID treatment was significantly associated with an increased risk of death/recurrent MI (hazard ratio, 1.45; 95% confidence interval, 1.29 to 1.62) at the beginning of the treatment, and the risk persisted throughout the treatment course (hazard ratio, 1.55; 95% confidence interval, 1.46 to 1.64 after 90 days). Analyses of individual NSAIDs showed that the traditional NSAID diclofenac was associated with the highest risk (hazard ratio, 3.26; 95% confidence interval, 2.57 to 3.86 for death/MI at day 1 to 7 of treatment). CONCLUSIONS: Even short-term treatment with most NSAIDs was associated with increased risk of death and recurrent MI in patients with prior MI. Neither short- nor long-term treatment with NSAIDs is advised in this population, and any NSAID use should be limited from a cardiovascular safety point of view. http://circ.ahajournals.org/content/123/20/2226.full.pdf  Atentamente Anestesiología y Medicina del Dolor www.anestesia-dolor.org

Núcleo ceruleus/Locus coeruleus

Las neuronas noradrenérgicas en el núcleo ceruleus contribuyen al dolor neuropático  Noradrenergic neurons in the locus coeruleus contribute to neuropathic pain. Brightwell JJ, Taylor BK. Department of Pharmacology, School of Medicine, Tulane University, New Orleans, LA 70112, USA. Neuroscience. 2009 Apr 21;160(1):174-85. doi: 10.1016/j.neuroscience.2009.02.023. Epub 2009 Feb 14. Abstract Current theories of neuropathic hypersensitivity include an imbalance of supraspinal inhibition and facilitation. Our overall hypothesis is that the locus coeruleus (LC), classically interpreted as a source of pain inhibition, may paradoxically result in facilitation after tibial and common peroneal nerve transection (spared sural nerve injury--SNI). We first tested the hypothesis that non-noxious tactile hind paw stimulation of the spared sural innervation territory increases neuronal activity in the LC in male rats. We observed a bilateral increase in the stimulus-evoked expression of transcription factors Fos and phosphorylated CREB (pCREB) in LC after SNI but not sham surgery; these markers of neuronal activity correlated with the intensity of tactile allodynia. We next tested the hypothesis that noradrenergic neurons contribute to the development of neuropathic pain. To selectively destroy these neurons, we delivered antidopamine-beta-hydroxylase saporin (anti-DbetaH-saporin) into the i.c.v. space 2 weeks before SNI. We found that anti-DbetaH-saporin, but not an IgG-saporin control, reduced behavioral signs of tactile allodynia, mechanical hyperalgesia, and cold allodynia from 3 to 28 days. after SNI. Our final experiment tested the hypothesis that the LC contributes to the maintenance of neuropathic pain. We performed SNI, waited 2 weeks for maximal allodynia and hyperalgesia to develop, and then administered the local anesthetic lidocaine (4%) directly into the LC parenchyma. Lidocaine reduced all behavioral signs of neuropathic pain in a reversible manner, suggesting that the LC contributes to pain facilitation. We conclude that, in addition to its well-known inhibition of acute and inflammatory pain, the LC facilitates the development and maintenance of neuropathic pain in the SNI model. Further studies are needed to determine the facilitatory pathways emanating from the LC. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2677992/pdf/nihms98071.pdf   Plasticidad molecular y celular inducida por opioides en las neuronas catecolaminérgicas del área tegmentaria ventral y el locus ceruleus   Opiate-induced molecular and cellular plasticity of ventral tegmental area and locus coeruleus catecholamine neurons.

Cold Spring Harb Perspect Med. 2012 Jul;2(7):a012070 . doi: 10.1101/cshperspect.a012070. Abstract The study of neuronal adaptations induced by opiate drugs is particularly relevant today given their widespread prescription and nonprescription use. Although much is known about the acute actions of such drugs on the nervous system, a great deal of work remains to fully understand their chronic effects. Here, we focus on longer-lasting adaptations that occur in two catecholaminergic brain regions that mediate distinct behavioral actions of opiates: ventral tegmental area (VTA) dopaminergic neurons, important for drug reward, and locus coeruleus (LC) noradrenergic neurons, important for physical dependence and withdrawal. We focus on changes in cellular, synaptic, and structural plasticity in these brain regions that contribute to opiate dependence and addiction. Understanding the molecular determinants of this opiate-induced plasticity will be critical for the development of better treatments for opiate addiction and perhaps safer opiate drugs for medicinal use. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3385942/pdf/cshperspectmed-ADD-a012070.pdf     Núcleo Coeruleus.

Abstract Tapia's syndrome is the palsy of the 10th and 12th cranial nerves, resulting in ipsilateral paralysis of the vocal cord and tongue. It is a rare complication which is related to the anesthetic airway management and positioning of the patient's head during the surgery. We describe a patient with a postoperative unilateral Tapia's syndrome, after general anesthesia, with uncomplicated endotracheal intubation. The patient's symptoms improved gradually for three months. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3581789/pdf/kjae-64-172.pdf    Megaesófago: Un reto para los anestesiólogos  Megaesophagus: A challenge for anesthesiologists. Tewari P, Gupta D. Ann Card Anaesth [serial online] 2013 [cited 2013 Jan 2];16:61-2.  A fifty-nine-year male farmer presented with a history of low grade dysphagia, both for solids and liquids for twenty-five years that progressively increased in severity. He had lost weight significantly in recent years and developed spontaneous regurgitation of liquids and food content, heart burn, chest pain after eating and cough. Chest X-ray (PA-view) showed a large curvilinear, radio-opaque density lesion occupying medial 2/3 rd of right hemi thorax with Ryle's tube within the shadow suggesting a large dilated esophagus. This was not silhouetting the right cardiac border suggesting posterior mediastinal mass; moreover, there was no mediastinal shift. Barium swallow confirmed achalasia-cardia with huge, more than 10 cm in diameter, pouch of esophagus with lower constricted part. The patient did not show any cardiac compromise but lung function tests showed reduced inspiratory and forced vital capacity (60%) and borderline Peak Expiratory Flow Rate (70%). The laboratory investigations were within normal limits. He was planned for transhiatal esophagectomy (THO) with cervical esophago-gastrotomy (OG) and feeding jejunostomy (FJ). He was given one week of rigorous chest physiotherapy under guidance of professional therapists http://www.annals.in/text.asp?2013/16/1/61/105374    Síndrome de Sturge-Weber con manifestaciones oculares extremas y asociación rara con agioma de la vía aérea superior con dificultad anticipada para el manejo de la vía aérea              Sturge-Weber-Syndrome with extreme ocular manifestation and rare association of upper airway angioma with anticipated difficult airway.

Abstract We report a rare case of an 18 year old girl with Sturge-Weber syndrome, she had extensive facial port wine stains, right bupthalmos and advanced glaucoma involving both eyes. She underwent right eye glaucoma drainage device surgery under general anaesthesia, and had a difficult intubation due to extensive angiomatous like soft tissue swelling at her upper airway. This report highlights the importance of being aware of the need for continuous follow-up in Sturge-Weber syndrome patients as this syndrome can lead to blindness due to advance glaucoma and the awareness of possible difficult intubation for this group of patients http://www.e-mjm.org/2012/v67n4/Sturge-Weber-Syndrome.pdf  Atentamente Anestesiología y Medicina del Dolor www.anestesia-dolor.org

Comparación de los efectos maternos y neonatales de bupivacaína más fentanil y ropivacaína más fentanil durante operación cesárea  Comparison of the maternal and neonatal effects of bupivacaine plus fentanyl and ropivacaine plus fentanyl during cesarean delivery. Canan U, Örnek D, Kilci O, Dönmez F, Gamli M, Dikmen B. Niger J Clin Pract [serial online] 2013 [cited 2013 Apr 6];16:195-200. Abstract Purpose: The aim of the present study was to compare the anesthetic efficacy, and fetal and maternal effects of 7.5 mg (1 ml) intrathecal 0.75% hyperbaric ropivacaine + 25 μg (0.5 ml) fentanyl versus 5 mg (l ml) intrathecal 0.5% hyperbaric bupivacaine + 25 μg (0.5 ml) fentanyl in elective cesarean delivery. Materials and Methods: The study included 40 ASA I-II cases scheduled for cesarean delivery that were randomized into two groups of 20 cases each. Cases in the RF group were administered 0.75% hyperbaric ropivacaine + 25 μg (0.5 ml) fentanyl and those in the BF group were administered 5 mg (l ml) hyperbaric bupivacaine + 25 μg (0.5 ml) fentanyl into the spinal space. The time until spinal anesthesia in the T4 dermatome, overall duration of analgesia, hemodynamic parameters, Apgar score of newborns at 1-5 min, fetal blood gas values (pH, PO2, PCO2, HCO3−, and BE), maternal side effects, the degree of motor block, maternal need for ephedrine, objective pain scale score, and patient satisfaction were recorded in each group. Results: There were no significant differences between the groups in terms of the parameters evaluated (P > 0.05). Conclusion: In elective cesarean delivery, the combinations of bupivacaine + fentanyl or ropivacaine + fentanyl exhibited similar anesthetic efficacy, and fetal and maternal effects. Keywords: Bupivacaine, cesarean, opioid, ropivacaine. http://www.njcponline.com/text.asp?2013/16/2/195/110154 Atentamente Dr. Benito Cortes-Blanco Anestesiología y Medicina del Dolor www.anestesia-dolor.org
