Dexmedetomidina en el manejo de la vía aérea difícil con fibrobroncoscopio en paciente despierto afecto de síndrome de Klippel-Feil

Klippel-Feil Syndrome is a disease characterised by congenital fusion of cervical vertebra, which leads to cervical limitation and instability. In these cases, the best option is the orotracheal intubation with the fibre-optic bronchoscope with the patient awake. The advantage is that cervical movements that could lead to neurological damage are minimised. In these patients, adequate sedation, together with instillation of local anaesthetic in the pharynx and hypopharynx, is the key to reducing patient discomfort and achieving successful orotracheal intubation. Dexmedetomidine is a selective α2- adrenergic receptor agonist that produces sedation and analgesia at the locus coeruleus without producing respiratory depression, as well as maintaining patient collaboration. The case is presented of a patient with Klippel-Feil Syndrome and difficult airway management, who was given a dexmedetomidine infusion at 0.6 μg/kg/h as sedation for an awake fibre-optic endotracheal intubation.     

Estudio poblacional de casuística y morbimortalidad de la prostatectomía radical en España

IntroductionThere is no population-based study that accounts for the number of radical prostatectomies (RP) carried out in Spain, nor regarding the morbidity and mortality of this intervention.Our objective is to study the morbidity and mortality of RP in Spain from 2011 to 2015 and to evaluate the geographic variation.Material and methodsWe designed a retrospective observational study of all patients submitted to RP in Spain during five consecutive years (2011-2015). The data was extracted from the «Conjunto Mínimo Básico de Datos» (CMBD).We have evaluated geographic variations in terms of morbidity and hospital stay, and the impact of the mean annual surgical volume for each center on these variables.ResultsBetween 2011-2015, a total of 37,725 RPs were performed in 221 Spanish public hospitals. The mean age of the series was 63.9 ± 3.23 years. Of all RPs, 50% were performed through an open approach, and 43.4% have been operated on in hospitals with < 500 beds. We observed an important variability in the distribution of the cases operated on in the different regions. The regions that perform more RPs are Andalusia, Catalonia, Galicia, and Madrid. Our study shows a complication rate of 8.6%, with hemorrhage and the need for transfusion being the most frequent (5.3 and 4%, respectively). There are significant differences in bleeding rates and hospital stay among regions, which are maintained after adjusting for patient characteristics and type of hospital. When studying the annual surgical volume of each hospital, we find that the impact on the rate of hemorrhage or transfusion is linear; however, hospital stay remains stable at around 5 days from 60 RPs/year.ConclusionsIn national terms, morbidity and mortality rates after RP are comparable to those described in the literature. This study reveals a clear dispersion in the hospitals that carry out this intervention, showing clear differences in terms of morbidity and hospital stay between the different regions.     

Experiencia de traumatismo renal abierto en un Servicio de Urología

IntroductionOpened renal trauma in urban areas reaches 15 to 20% of all renal traumas. It is mainly caused by gunshot wounds or knifes. Gunshot wounds are classified as high energy trauma and are usually associated to other organ injuries. We present our experience in opened renal trauma in the last 24 months.Material and methodsRetrospective study: patients with thoracic, abdominal and thoraco-abdominal trauma admitted to the emergency room between July 2009 and June 2011 were studied. Fourteen patients were identified with opened renal trauma, with diagnostic confirmation by imaging study or during surgery.ResultsAges ranged from 16 to 37 years, with a mean age of 24.5 years. Thirteen patients were males. The mechanism of injury was produced by gunshot in 71% (10/14) and by knife in 29% (4/14). The opened renal traumas were classified according to the American Association for the Surgery of Trauma. Of these, 3/14 (21%) belonged to grade II, 4/14 (29%) to grade III, 4/14 (29%) to grade IV and 3/14 to grade V (21%). Fall in hematocrit ranged from 1% to 27%, with an average of 13.9%. Expectant management was done in six patients, however, this management did not take into account those surgeries performed due to non-urologic organ injuries. Six patients (42%) required nephrectomy. Thoraco-abdominal injuries were associated in 11 patients (79%).ConclusionsDespite the low incidence of opened renal trauma, many patients are observed when other national reports are considered, probably due to the socio-cultural characteristics of this hospital.     

Factibilidad y morbimortalidad en doscientos casos consecutivos de pancreaticogastrostomía después de duodenopancreatectomía

BackgroundPostoperative mortality associated with pancreaticoduodenectomy (PD) in high-volume hospitals is below 5%, yet morbidity rates range between 45% and 60%. Recent studies show a lower incidence of complications and postoperative pancreatic fistula (POPF) in pancreaticogastrostomy (PG). The primary objective was to assess the incidence and predictive factors for complications: POPF, post-pancreatectomy hemorrhage (PPH) and delayed gastric emptying (DGE) following the criteria of the ISGPS and Clavien-Dindo classifications.MethodsA prospective observational study that included all patients who underwent PD between 2008 and 2016. PG was the surgical procedure of choice for PD reconstruction.ResultsTwo hundred forty-nine patients underwent surgery with intention of performing a PD. The feasibility of PG was 90.5%. One hundred and six (53%) patients had complications, 36 (18%) were severe (Clavien-Dindo grade ≥III). Death within 90 postoperative days was 4%. DGE was the most frequent complication (22.5%), followed by PPH (21%). The clinical POPF rate was 15% (6% Clavien-Dindo grade ≥III). The primary risk factors associated with complications were age >70 years (1.9 [1-3.55]), being male (1.89 [1; 3.6]) and soft pancreatic texture (3.38 [1.5; 7.37]).ConclusionsIn this paper, we report a feasibility study for PG (90.5%). The primary risk factors associated with complications were age >70 years, being male and soft pancreatic texture. Soft pancreatic texture is also associated with the development and severity of POPF.     

Clevidipino como antihipertensivo en la cirugía de feocromocitoma

Pheochromocytoma is a catecholamine-producing tumour and laparoscopic adrenalectomy is its treatment of choice. During pneumoperitoneum insufflation and tumour handling there is a high risk of massive catecholamine release and hypertensive crisis. After tumour excision, severe arterial hypotension is a common effect, due to relative vasodilation and the residual effect of antihypertensive drugs. We report the case of a patient with pheochromocytoma who was treated with laparoscopic adrenalectomy. During surgical manipulation there was a sudden hypertensive peak that could be controlled quickly with clevidipine infusion. After tumour resection, clevidipine perfusion was stopped and there were no arterial hypotension episodes. Clevidipine is a new intravenous calcium antagonist with rapid onset of action and short half-life that has no residual effect and does not produce arterial hypotension after tumour resection. For these reasons, it can be a first-choice drug for this kind of surgery.

Cirugía en directo: estudio de seguridad tras 17 ediciones de cirugía retroperitoneoscópica

IntroductionLive surgery has become an excellent tool for medical training. Despite this, there is controversy about the safety of the patients involved.ObjectiveTo analyze the results of live surgeries performed in 17 consecutive retroperitoneoscopy courses organized in our center. Procedures performed were partial nephrectomy (PN), radical nephrectomy (RN) and nephroureterectomy (NU).Material and methodsReview from January 2010 to October 2017 of all live surgeries carried out by an expert surgical team in the retroperitoneoscopy courses, compared with a control group of surgeries performed in standard conditions. A matching (1:1 for each RN and 1:2 for each PN and NU) according to age, body mass index and comorbidities was performed.ResultsTwenty-one live surgeries were analyzed (eight PN, seven RN and six NU) with a global median follow-up of 38 months. No significant differences were observed between both groups in terms of perioperative variables (operative time, operative bleeding and intraoperative complications) or of postoperative complications and length of hospital stay. Likewise, there were no differences between recurrence rates (PN: 0% vs. 6.3%, p = 0.47, NU: 33.3% vs. 66.7%, p = 0.180, RN: 0% vs. 28.6%, p = 0,127).ConclusionsLive surgery in the hands of expert surgeons in a suitable environment and with well-selected patients does not increase the risk of complications and allows maintaining the same oncological outcomes.

Diagnóstico intraoperatorio de red de Chiari basado en ecocardiografía

We report a case of a Chiari network as a possible cause of intraoperative supraventricular tachycardia with potential cardiac flow obstruction and hemodynamic collapse. The intraoperative diagnostic analysis considered detects cardiac abnormalities associated to this congenital remnant and discard common intraoperative causes of hemodynamic alterations.     

Manejo anestésico en la cirugía de epilepsia con electrocorticografía intraoperatoria

Epilepsy surgery is a well-established treatment for patients with drug-resistant epilepsy. The success of surgery depends on precise presurgical localisation of the epileptogenic zone. There are different techniques to determine its location and extension. Despite the improvements in non-invasive diagnostic tests, in patients for whom these tests are inconclusive, invasive techniques such intraoperative electrocorticography will be needed.Intraoperative electrocorticography is used to guide surgical resection of the epileptogenic lesion and to verify that the resection has been completed. However, it can be affected by some of the anaesthetic drugs used by the anaesthesiologist. Our objective with this case is to review which drugs can be used in epilepsy surgery with intraoperative electrocorticography.     

Manejo de la vía aérea en una paciente con síndrome de Treacher Collins en 2 tiempos quirúrgicos

Treacher Collins syndrome (TCS), Franceschetti-Zwahlen-Klein, or mandibulofacial dysostosis, is a rare disorder of craniofacial development (incidence of approximately 1:50.000 live births). TCS is relevant to the anaesthetist because it can cause difficulties in airway management.A case report is presented of a 24 year-old woman who was referred to our institution for facial reconstruction surgery in two stages. In both surgeries Airtraq? was essential for airway management.By presenting this case, it is intended to show that planning, communication and teamwork are indispensable for patient safety.     

Duodenopancreatectomía en ancianos. Evaluación de resultados

IntroductionWith the increase in life expectancy, more and more resectable periampullary tumours are being diagnosed in the geriatric population. Despite the decrease in post-operative mortality, there continues to be a debate on the risk-benefit of cephalic duodenopancreatectomy (CPD) in the elderly.ObjectiveTo analyse the morbidity and mortality of CPD in patients over 70 years-old.DesignProspective observational study.PatientsA total of 54 duodenopancreatectomies were performed between January 2005 and December 2010. Two groups of patients were compared: Group 1 (patients > 70 years-old, n: 24), and Group 2 (patients < 70 years-old, n: 30). The morbidity and mortality, transfusion, reinterventions, mean hospital stay, and survival were analysed.ResultsThe > 70 years group included more ASA 2 and 3 patients (P=.010), and had a higher number of previous medical problems per patient (P=.037). The post-operative mortality was higher in the older age group, although the difference was not significant (8.3 vs 3.3%). There were also no significant differences in post-operative morbidity (45.8 v. 46.6%), reintervention rate (16.6 vs 13.3%), length of hospital stay (18 vs 13%), and survival at 6 and 12 months (84 and 72% vs 90 and 86%).ConclusionsAge, in itself, does not seem to be a contraindication for CPD, but the elderly do have a higher risk of complications due to the physiological changes associated with ageing. The disparity of results demonstrates the need for more population studies at national level that may give an overall view of morbidity and mortality in CPD.

Terapia de presión negativa en cirugía de la pared abdominal

Negative pressure wound therapy (NPWT) is widely known in surgical practice. The initial indications for NPWT were chronic wounds, especially diabetic foot, vascular and decubitus ulcers, and infected traumatic wounds. Nowadays, the use has been widely increased. Although in the field of abdominal wall surgery, it has mainly been used in the treatment of surgical wound complications after hernia repair, other indications have been added after years of experience in the management of NPWT.Therefore, the aim of this article is to analyze and review the main indications of NPWT in abdominal wall surgery, as well as the advantages obtained with its application.     

Encuesta multicéntrica sobre el empleo de la ecocardiografía intraoperatoria en cirugía cardiovascular en España. Artículo breve

Transesophageal echocardiography (TEE) is an essential tool in the intraoperative and postoperative period of cardiac surgery with recently wide diffusion. We aimed to know the current situation of TEE in the field of cardiovascular anesthesiology in Spain through a national survey that explores the availability of equipment, indication and use of this technique as well as the training and accreditation of professionals involved. The findings show that in Spain intraoperative TEE is an integral part of cardiovascular procedures today and in most centers it is performed by anesthesiologists highly involved in this type of surgery. Despite the absence of structured training in the curriculum of our specialty, anesthesiologists acquire the skills through specific short-term rotations and a high percentage of them have obtained official accreditation.
