Incendios en cirugía/Surgical fires
Fuego quirúrgico. Un reto intraoperatorio
Surgical fires: An ongoing intra-operative challenge.
Abdulrasheed I, Lawal AM, Eneye AM.
Arch Int Surg [serial online] 2013 [cited 2013 Aug 28];3:1-5.
Abstract
Background: A surgical fire is a rare but life-threatening event. They are always unexpected and commonly occur in head and neck surgeries resulting in severe burns, disfigurement, and in some cases death. Injuries are not limited to patients alone as they may also involve health-care personnel in the operating theater. There is a resurgence in the awareness of this intra-operative challenge as well as an understanding of the need for a team approach to prevention. Materials and Methods: The surgical fire triangle is a useful paradigm that describes the three elements necessary for initiation of a surgical fire i.e., ignition source, fuel, and an oxidizer. This review will identify operating theatre contents capable of acting as ignition/oxidizer/fuel sources and highlight the management and prevention of surgical fires. Results: Surgical fires can be prevented by education across all professional boundaries in the operating theater. This will entail information on how the elements of the fire triangle interact, recognizing how standard operating room equipment can initiate a fire, and vigilance for the circumstances that increase the likelihood of a surgical fire. Conclusion: Promoting a culture of fire safety in the theater is not optional. Education on the prevention of surgical fires should be included in the curriculum of undergraduate medical students. There is an urgent need to stimulate debate within National burn associations in this context, leading to the formation of proposals to be incorporated into existing National burn prevention plans.

Abstract
A fire on or within a surgical patient is a continuing risk in modern surgery. Unfortunately, the sensitivity of surgical and anaesthesia staff to this hazard has waned over the past 25 years with cessation of the use of flammable anaesthetic agents. Prevention of surgical fires requires understanding the risks and effective communication between surgical, anaesthesia, and operating nursing staffs. Preventive measures exist but have yet to diffuse sufficiently across professional boundaries. Based on a review of relevant databases, decades of experience from field investigations, and a review of the medical literature, this paper discusses the incidence of surgical fires, the responsibility for prevention in the perioperative setting, and the procedures for surgical fire prevention and extinguishment.

Abstract
The three surgical patient safety events, wrong site surgery, retained surgical items (RSI) and surgical fires are rare occurrences and thus their effects on the complex modern operating room (OR) are difficult to study. The likelihood of occurrence and the magnitude of risk for each of these surgicalsafety events are undefined. Many providers may never have a personal experience with one of these events and training and education on these topics are sparse. These circumstances lead to faulty thinking that a provider won't ever have an event or if one does occur the provider will intuitively know what to do. Surgeons are not preoccupied with failure and tend to usually consider good outcomes, which leads them to ignore or diminish the importance of implementing and following simple safety practices. These circumstances contribute to the persistent low level occurrence of these three events and to the difficulty in generating sufficient interest to resource solutions. Individual facilities rarely have the time or talent to understand these events and develop lasting solutions. More often than not, even the most well meaning internal review results in a new line to a policy and some rigorous enforcement mandate. This approach routinely fails and is another reason why these problems are so persistent. Vigilance actions alone have been unsuccessful so hospitals now have to take a systematic approach to implementing safer processes and providing the resources for surgeons and other stakeholders to optimize the OR environment. This article discusses standardized processes of care for mitigation of injury or outright prevention of wrong site surgery, RSI and surgical fires in an action-oriented framework illustrating the strategic elements important in each event and focusing on the responsibilities for each of the three major OR agents-anesthesiologists, surgeons and nurses. A Surgical Patient Safety Checklist is discussed that incorporates the necessary elements to bring these team members together and influence the emergence of a safer OR.

Abstract
A few cases of fire in the operating room are reported in the literature. The factors that may initiate these fires are many and include alcohol based surgical prep solutions, electrosurgical equipment, flammable drapes etc. We are reporting a case of fire in the operating room while operating on a patient with burst fracture C6 vertebra with quadriplegia. The cause of the fire was due to incomplete drying of the covering drapes with an alcohol based surgical prep solution. This paper discusses potential preventive measures to minimize the incidence of fire in the operating room.

Embarazo/Pregnancy
El ojo y el sistema visual durante el embarazo. ¿Que esperara? Una revisión profunda
The eye and visual system in pregnancy, what to expect? An in-depth review.
Samra KA.
Oman J Ophthalmol [serial online] 2013 [cited 2013 Aug 20];6:87-91.
Abstract
Pregnancy represents a real challenge to all body systems. Physiological changes can involve any of the body organs including the eye and visual system. The ocular effect of pregnancy involves a wide spectrum of physiologic and pathologic changes. The latter might be presenting for the first time during pregnancy such as corneal melting and corneal ectasia, or an already existing ocular pathologies that are modified by pregnancy such as diabetic retinopathy and glaucoma. In addition, pregnancy can affect vision through systemic disease that are either specific to the pregnant state itself such as the pre-eclampsia/eclampsia and Sheehan's syndrome, or systemic diseases that occur more frequently in relation to pregnancy such as Graves' disease, idiopathic intracranial hypertension, anti-phospholipid syndrome, and disseminated intravascular coagulation.

Apendicitis aguda en el embarazo
Acute appendicitis in pregnancy
Sanda RB, Garba SE.
Arch Int Surg [serial online] 2013 [cited 2013 Aug 28];3:6-10.
Abstract
Background: Frequently, a general surgeon is called upon to consider the diagnosis of appendicitis in a girl or woman who is pregnant or has recently delivered. The burden of clinical decision-making and execution of treatment would rest on the general surgeon, with other specialists playing peripheral, but important supportive roles. This condition is relatively rare in pregnancy. A delay in operative intervention is often incurred in view of the risk of general anesthesia and operation on the fate of the pregnancy. Promptly diagnosed in a patient who sought medical assistance early in the evolution of the disease, acute appendicitis in pregnancy (AAP) should not pose an operative challenge to the contemporary surgeon or risk to the woman and her unborn child. It is the aim of this review to appraise AAP in the light of contemporary evidence based medicine and to demystify it with a view to encouraging general surgeons to boldly confront a potentially lethal disease and not to add to the patient's suffering by hiding behind unnecessary laboratory and imaging investigations. Materials and Methods: Many search engines are used such as MedLine, PubMed and Google scholar to search out discussions related to AAP. All the acquired information was processed to arrive at the conclusions drawn here in this essay. Results: AAP can be promptly diagnosed and treated with high index of suspicion. Awareness of this condition in pregnant patients must be high. The condition if diagnosed early and treated promptly can have a good outcome. Conclusion: Acute appendicitis is a relatively rare condition in pregnancy; surgeons must have a high index of suspicion as early diagnosis and treatment are important factors in a safe outcome of this condition.

Resumen
Los cambios hemodinámicos que se producen durante el embarazo son máximos entre las 28.a y 34.a semanas. En una gestante con enfermedades asociadas o coincidentes, como cardiopatía hipertensiva y diabetes pregestacional estos cambios pueden dar lugar a una hipertensión pulmonar y edema agudo de pulmón de difícil control. Presentamos el caso de una gestante diabética tipo 1 de varios años de evolución, que presentó un cuadro de preeclampsia en un embarazo anterior y que desarrolló una miocardiopatía hipertensiva desde entonces. Había ingresado en la 30.a semana de gestación para control metabólico y de la presión arterial desarrollando una insuficiencia cardiaca congestiva tras la administración de betametasona para maduración pulmonar fetal. Se le realizó un ecocardiograma transtorácico que mostró un ventrículo izquierdo hipertrófico no dilatado con buena función sistólica, alteración diastólica restrictiva e hipertensión arterial pulmonar moderada. Cuando se consiguió mejorar su estado general se decidió realizar una cesárea con anestesia regional para evitar las complicaciones de la hipertensión arterial pulmonar y sistémica. Exponemos el tratamiento anestésico y la resolución de las complicaciones aparecidas tras la administración de oxitocina.

Abstract
Background: Obstetrical acute renal failure ARF is now a rare entity in the developed countries but still a common occurrence in developing countries. Delay in the diagnosis and late referral is associated with increased mortality. This study aimed to evaluate the contributing factors responsible for pregnancy-related acute kidney failure, its relation with mortality and morbidity and outcome measures in these patients. Materials and Methods: Total 520 patients of ARF of various aetiology were admitted, out of these 60 (11.5%) patients were pregnancy-related acute renal failure. Results: ARF Acute renal failure occurred in 32 (53.3%) cases in early part of their pregnancy, whereas in 28 (46.7%) cases in later of the pregnancy. Thirty-two (53.3%) patients had not received any antenatal visit, and had home delivery, 20 (33.4%) patients had delivered in hospitals but without antenatal care and eight (13.3%) patients received antenatal care and delivered in the hospitals. Anuria was observed in 23 (38.3%) cases, remaining 37 (61.7%) cases presented with oliguria. Septicemia was present in 25 (41.7%), hypertensive disorder of pregnancy in 20 (33.3%), haemorrhage in eight (13.3%), abortion in 5 (8.3%), haemolysis elevated liver enzymes low platelets counts (HELLP) syndrome in one (1.67%) and disseminated intravascular coagulation in one (1.67%). (61.7%) patients were not dialyzed, 33 (55%) recovered normal renal function with conservative treatment. Complete recovery was observed in 45 (75%) patients, five (8.4%) patients developed irreversible renal failure. Maternal mortality was nine (15%) and foetal loss was 25 (41.7%). Conclusion: Pregnancy-related ARF is usually a consequence of obstetric complications; it carries very high morbidity and mortality.

Más sobre anestesia peridural/More on peridural anesthesia
El Dr. Alberto Gutiérrez, de Argentina, realizó diversos cursos y trabajos sobre anestesia metamérica epidural y basándose en los estudios de Jansen sobre la presión negativa en el espacio epidural (EE). En 1933 publicó un artículo en el que llamó la atención sobre la importancia de la aspiración de líquidos hacia el EE. De ahí surge el signo conocido como "aspiración de la gota" o "gota pendiente" de Gutiérrez".

Resumen
Gran parte del éxito de una anestesia epidural se basa en la correcta identificación del espacio epidural. En los últimos 100 años se han descrito numerosas técnicas intentando localizar el espacio de la manera más simple, efectiva, segura y fiable. Para juzgar las técnicas empleadas para la identificación del espacio epidural, sus ventajas, inconvenientes y/o complicaciones se ha realizado una búsqueda en Medline entrecruzando las palabras clave "epidural analgesia", "epidural anesthesia", "epidural space", "identification" y "loss of resistance". Se analizan las técnicas clásicas de identificación del espacio epidural, así como los principales métodos complementarios o instrumentales. Se evalúan los resultados de los ensayos clínicos en los que se comparan las distintas técnicas de pérdida de resistencia (LOR). Las técnicas basadas en la LOR, mediante el uso de aire, solución salina isotónica o una combinación de ambos, han demostrado ser las más simples y efectivas. Con respecto a la seguridad, la técnica de LOR con aire es la que presenta más complicaciones (neumoencéfalo, embolismo aéreo, analgesia insuficiente, mayor incidencia de punciones durales accidentales, compresión de raíces nerviosas, enfisema subcutáneo). Si a la técnica de LOR con solución salina, se le agrega una pequeña burbuja de aire dentro de la jeringa, la técnica, además de efectiva y segura, resulta más fiable y su enseñanza más didáctica.

Abstract
BACKGROUND: Epidural Anesthesia (EA) is a well-established procedure. The aim of the present study was to evaluate the incidence of immediatecomplications following epidural puncture, such as sanguineous puncture, accidental dural perforation, unsuccessful catheter placement or insufficient analgesia and to identify patient and maneuver related risk factors. METHODS: A total of 7958 non-obstetrical EA were analyzed. The risk of each complication was calculated according to the preconditions and the level of puncture. For probabilistic evaluation we used a logistic regression model with forward selection. RESULTS:The risk of sanguineous puncture (n = 247, 3.1%) increases with both the patient's age (P = 0.013) and the more caudal the approach (P < 0.01). Dural perforation (n = 123, 1.6%) was found to be influenced only by advanced age (P = 0.019). Unsuccessful catheter placement (n = 68, 0.94%) occurred more often in smaller individuals (P < 0.001) and at lower lumbar sites (P < 0.01). Amongst all cases with successful catheter placement a (partial) insufficient analgesia was found in 692 cases (8.8%). This risk of insufficient analgesia decreased with patient's age (P <0 .01), being least likely for punctures of the lower thoracic spine (P < 0.001). CONCLUSIONS:Compared to more cranial levels, EA of the lower spine is associated with an increased risk of sanguineous and unsuccessful puncture. Insufficient analgesia more often accompanies high thoracic and low lumbar approaches. The risk of a sanguineous puncture increases in elderly patients. Gender, weight and body mass index seem to have no influence on the investigated complications.

Para juzgar las técnicas empleadas para la identificación del espacio epidural, sus ventajas, inconvenientes y/o complicaciones se ha realizado una búsqueda en Medline entrecruzando las palabras clave "epidural analgesia", "epidural anesthesia", "epidural space", "identification" y "loss of resistance". Se analizan las técnicas clásicas de identificación del espacio epidural, así como los principales métodos complementarios o instrumentales. Se evalúan los resultados de los ensayos clínicos en los que se comparan las distintas técnicas de pérdida de resistencia (LOR). Las técnicas basadas en la LOR, mediante el uso de aire, solución salina isotónica o una combinación de ambos, han demostrado ser las más simples y efectivas. Con respecto a la seguridad, la técnica de LOR con aire es la que presenta más complicaciones (neumoencéfalo, embolismo aéreo, analgesia insuficiente, mayor incidencia de punciones durales accidentales, compresión de raíces nerviosas, enfisema subcutáneo). Si a la técnica de LOR con solución salina, se le agrega una pequeña burbuja de aire dentro de la jeringa, la técnica, además de efectiva y segura, resulta más fiable y su enseñanza más didáctica.

Abstract
BACKGROUND: Epidural Anesthesia (EA) is a well-established procedure. The aim of the present study was to evaluate the incidence of immediatecomplications following epidural puncture, such as sanguineous puncture, accidental dural perforation, unsuccessful catheter placement or insufficient analgesia and to identify patient and maneuver related risk factors. METHODS: A total of 7958 non-obstetrical EA were analyzed. The risk of each complication was calculated according to the preconditions and the level of puncture. For probabilistic evaluation we used a logistic regression model with forward selection. RESULTS:The risk of sanguineous puncture (n = 247, 3.1%) increases with both the patient's age (P = 0.013) and the more caudal the approach (P < 0.01). Dural perforation (n = 123, 1.6%) was found to be influenced only by advanced age (P = 0.019). Unsuccessful catheter placement (n = 68, 0.94%) occurred more often in smaller individuals (P < 0.001) and at lower lumbar sites (P < 0.01). Amongst all cases with successful catheter placement a (partial) insufficient analgesia was found in 692 cases (8.8%). This risk of insufficient analgesia decreased with patient's age (P <0 .01), being least likely for punctures of the lower thoracic spine (P < 0.001). CONCLUSIONS:Compared to more cranial levels, EA of the lower spine is associated with an increased risk of sanguineous and unsuccessful puncture. Insufficient analgesia more often accompanies high thoracic and low lumbar approaches. The risk of a sanguineous puncture increases in elderly patients. Gender, weight and body mass index seem to have no influence on the investigated complications.

Abstract
BACKGROUND: The anatomical landmark which is used to identify the correct level for lumbar puncture is the line connecting both iliac crests. This crosses the vertebra column at the level of the L4-L5 intervertebral space or L4 vertebra. It can be difficult to determine in a group of orthopaedic patients due to chronic orthopaedic disorders, chronic pain, overweight, or difficulties with positioning for lumbar puncture. The objective of this study was to determine if identification of intervertebral space by a physical exam differs from that of an ultrasound assessment. METHODS:Adult patients scheduled for lower limb surgery under spinal block were enrolled in this study. The intervertebral space suitable for lumbarpuncture was determined by physical exam by an anaesthetist in the sitting or lateral position. This was followed by a lumbar ultrasound. Primarily, a transducer was placed in paramedian sagittal view followed by transverse interlaminar view to confirm the identification of the interlaminar spaces. The 'counting-up' approach starting with the L5-1 space was applied. RESULTS: One hundred and twenty two patients (122) were included in this study. Lumbar intervertebral spaces were identified by ultrasound in all cases. There was concordance of intervertebral space identification (between clinical and ultrasound examination) in 78 cases (64%). Mean deviation of inacuracy was one intervertebral space with no statistical difference among cephalad and caudal direction. There were no statistically significant differences fund in terms of demographic data (sex, age, height, weight, or BMI), positioning for lumbar puncture, or intervertebral space chosen for the puncture between the concordant and the nonconcordant identification groups. The only statistically significant difference found was the difference in the years of experience of the anaesthetist performing the clinical assessment and puncture. CONCLUSIONS:The concordance rate between clinical examination and using assessment of intervertebral space identification for lumbar puncture is 64% among patients undergoing lower limb surgery. No special parameters were found which could make an anaesthetist aware that a patient is at greater risk of inadequate intervertebral space level assessment. Spinal ultrasound can reduce the incidence of inappropriate lumbar puncture level in orthopaedic patients.

Abstract
BACKGROUND AND OBJECTIVES: An imaginary line connecting both iliac crests is used to determine the vertebral level for lumbar puncture. This line crosses the spine at the level of L4 or the L4-L5 space. This anatomical reference can be inaccurate in a large proportion of patients. The objective of the present study was to determine whether the identification of the L3-L4 space by the physical exam differs from that of the ultrasound in obese and non-obese pregnant women. METHODS:Adult patients undergoing elective cesarean sections under spinal block participated in this study. Patients were divided in two groups: obese and non-obese. The L3-L4 space was determined by physical exam with the patient in the sitting position. This was followed by a lumbarultrasound. After the sacrum was identified, the transducer was directed in the cephalad direction to identify the spinous processes of the lumbarvertebrae. The clinically estimated L3-L4 level was recorded. RESULTS: Ninety patients, 43 obese and 47 non-obese, were included in this study. Lumbar intervertebral spaces were identified by ultrasound in all patients. The L3-L4 space clinically identified corresponded to the ultrasound identification in 53% and 49% of the cases in the non-obese and obese groups, respectively. There was no significant difference between groups. CONCLUSIONS:The L3-L4 space is correctly identified in a low percentage of obese and non-obese pregnant women. Spinal ultrasound can reduce the incidence of mistaken identification of the L3-L4 space in obese and non-obese pregnant women.

Abstract
BACKGROUND: The intercristal line is known to most frequently cross the L4 spinous process or L4-5 interspace; however, it is speculated to be positioned higher during pregnancy because of the exaggerated lumbar lordosis. Clinical estimation of vertebral levels relying on the use of the intercristal line has been shown to often be inaccurate. We hypothesized that the vertebral level of the intercristal line determined by palpation would be higher than the level determined by ultrasound in pregnant women. METHODS: Fifty-one term pregnant patients were recruited. Two experienced anesthesiologists performed estimates of the position of the intercristal line by palpation. Using ultrasound, another anesthesiologist who was blinded to the clinical estimates, determined the position of the superior border of the iliac crest in the transverse and longitudinal planes and then identified the lumbar vertebral levels. The vertebral level at which the clinical estimates of the intercristal line crossed the spine was recorded and compared with the ultrasound-determined level of the superior border of the iliac crest. RESULTS: The clinical estimates of the spinal level of the intercristal line agreed with the ultrasound measurement 14% of the time (14 of 101; 95% confidence interval [CI]: 8%, 22%). The clinical estimates were 1 level higher than the ultrasound measurement 23% of the time (23 of 101; 95% CI: 16%, 32%) and >1 level higher 25% of the time (25 of 101; 1-tailed 95% CI: >18%). The distribution of the clinical estimates found clinicians locating the intercristal line at L3 or L3-4 54% of the time (54 of 101; 95% CI: 44%, 63%) and at L2-3 or higher 27% of the time (27 of 101; 1-tailed 95% CI: >20%). CONCLUSION: The anatomical position of the intercristal line was at L3 or higher in at least 6% of term pregnant patients using ultrasound. Clinical estimates were found to be ≥1 vertebral level higher than the anatomical position determined by ultrasound at least 40% of the time. This disparity may contribute to misidentification of lumbar interspaces and increased risk of neurologic injury during neuraxial anesthesia.

Abstract
PURPOSE: To examine the history of pediatric endotracheal intubation and the issues surrounding the change from uncuffed endotracheal tubes to cuffed endotracheal tubes, including pediatric airway anatomy, endotracheal tube design, complications, and safety concerns. METHOD:Review of the literature. CONCLUSIONS:Although the use of cuffed endotracheal tubes in infants and children remains a topic of debate, the literature supports this change in practice. Meticulous attention must be given to intracuff pressure. Cuffed endotracheal tubes designed especially for the pediatric patient may increase the margin of safety.

Influencias del proceso de envejecimiento sobre el dolor perioperatorio en el viejo y en pacientes con daño cognitivo
Influencias del proceso de envejecimiento sobre el dolor perioperatorio en el viejo y en pacientes con daño cognitivo
Influences of the aging process on acute perioperative pain management in elderly and cognitively impaired patients.
Halaszynski T.
Department of Anesthesiology, Yale University School of Medicine, New Haven, CT.
Ochsner J. 2013 Summer;13(2):228-47.
Abstract
BACKGROUND: The aging process results in physiological deterioration and compromise along with a reduction in the reserve capacity of the human body. Because of the reduced reserves of mammalian organ systems, perioperative stressors may result in compromise of physiologic function or clinical evidence of organ insult secondary to surgery and anesthesia. The purpose of this review is to present evidence-based indications and best practice techniques for perioperative pain management in elderly surgical patients. RESULTS: In addition to pain, cognitive dysfunction in elderly surgical patients is a common occurrence that can often be attenuated with appropriate drug therapy. Modalities for pain management must be synthesized with intraoperative anesthesia and the type of surgical intervention and not simply considered a separate entity. CONCLUSIONS: Pain in elderly surgical patients continues to challenge physicians and healthcare providers. Current studies show improved surgical outcomes for geriatric patients who receive multimodal therapy for pain control.

Abstract
BACKGROUND: The aging process results in physiological deterioration and compromise along with a reduction in the reserve capacity of the human body. Because of the reduced reserves of mammalian organ systems, perioperative stressors may result in compromise of physiologic function or clinical evidence of organ insult secondary to surgery and anesthesia. The purpose of this review is to present evidence-based indications and best practice techniques for perioperative pain management in elderly surgical patients. RESULTS: In addition to pain, cognitive dysfunction in elderly surgical patients is a common occurrence that can often be attenuated with appropriate drug therapy. Modalities for pain management must be synthesized with intraoperative anesthesia and the type of surgical intervention and not simply considered a separate entity. CONCLUSIONS: Pain in elderly surgical patients continues to challenge physicians and healthcare providers. Current studies show improved surgical outcomes for geriatric patients who receive multimodal therapy for pain control.
