[Drainage time in patients submitted to radical neck dissection. Influence of peri-operative intravenous liquid perfusion]. / Tiempo de drenaje en pacientes sometidos a disección radical de cuello. La influencia de la perfusión de líquidos en el periodo perioperatorio.

INTRODUCTION: Drainage after radical neck dissection (RND) is routine and several factors impact the postoperative drainage number of days (PODND). OBJECTIVE: to determine the impact of trans-operative intravenous fluid management (TOFM) in in PODND. METHODS: Retrospective analysis of patients subjected to some type of radical neck dissection. Variables analyzed: blood loss volume, radical neck dissection type, surgical time, anesthesia time, and trans-operative intravenous fluid management volume. RESULTS: 120 patients included: average age 58.3 years; 60 males and 60 females. Radical neck dissection most frequent indications: thyroid cancer (36.6%), laryngeal cancer (15.8%) and tongue cancer (7.5%). Radical neck dissection most frequent types: 47 modified radical (39.2%), 22 lateral (18.3%) and 16 supra-omohyoid (13.3%). Median surgical time 3.55 hours, median anesthesia time 4.3 hours, median blood loss 278 ml, related to transoperative intravenous fluid management. Classical radical neck dissection was performed in 13 patients in whom postoperative drainage number of days was greater than in the other types (p = 0.08). No difference in postoperative drainage number of days among the different types of radical neck dissection. An apparent association was found between trans-operative intravenous fluid management volume and postoperative drainage number of days: the greater the quantity of fluids, the greater the number of days (p = 0.001). Patients who had drain removed during the first seven days had an average of 1,500 ml infused. Patients who had an average of 3,000 ml of fluid had drainage of 10 days. Perfusion > 3,500 ml = postoperative drainage number of days ≥ 10 días. CONCLUSIONS: In the present series a statistically significant relationship was found between the TOFM and PODND. A meticulous surgical technique and an anesthesia procedure that carefully assesses fluid balance could decrease PODND.

[Transoperative tamponade due to perforation with a catheter for central blood pressure: report and case analysis]. / Tamponade transoperatorio debido a perforación con catéter venoso central. Informe y análisis de un caso.

Pericardial tamponade due to myocardial perforation from central venous catheter is rather unusual, especially if it happens during a trans-operative period. When it comes up, it has a high mortality risk if the pericardial fluid is not drained at the proper time. At the Oncology Hospital of the National Medical Center, IMSS, Mexico City (Hospital de Oncología del Centro Médico Nacional, Siglo XXI), at the Anesthesia Service, a case of tamponade in transoperative period came up, after a surgical procedure that lasted more than 6 hours, and that manifested itself with signs of cardiogenic shock that did not improve with treatment. The etiology was not diagnosed until a postmortem study. If it had been diagnosed on time, its clinical evolution would have been different with an opportune and correct treatment.

Manejo anestésico en cirugía hepática, vía biliar y de páncreas

RESUMEN El paciente oncológico representa un reto intelectual y físico para el médico anestesiólogo. Dentro de la complejidad del tratamiento de cáncer, la cirugía hepática, de vía biliar y páncreas requieren consideraciones especiales. La epidemiología y el tipo de neoplasias específicas de esta zona del cuerpo hacen que los tratamientos quirúrgicos sean extensos y radicales para lograr ampliar la sobrevida de los pacientes. El manejo anestésico va encaminado a corregir y optimizar las comorbilidades del paciente previo a la cirugía. El transanestésico involucra un monitoreo invasivo para estabilizar hemodinámicamente al paciente y lograr mantener en adecuado plano anestésico a lo largo del procedimiento. La revisión que a continuación se expone es una actualización sobre la epidemiología y tipo de neoplasias que se involucran en esta zona. Se recuerdan los puntos importantes del manejo anestésico desde la valoración preoperatoria hasta el postoperatorio inmediato. Por último se sugiere un manejo anestésico óptimo basado en la literatura y en consensos de expertos en pacientes con estas condiciones.

SUMMARY Cancer patients are an intellectual and physical challenge for the anesthesiologist. Within the complexity of cancer treatment, surgery of liver, bile duct and pancreas requiere special attention. The specific types of neoplasmas in this area of the body along with their unique epidemiology, make surgical treatments to be radical with the objective of achieving a longer expectation of life. The anesthetic management is aimed to correct and optimize the patient´s comorbidities prior and during surgery. This involves invasive hemodynamic monitoring to keep the patient in an adequate level of anesthesia and stable in their neurologic, renal and cardiovascular variables. The review that is set out below is an update of the types of tumoral diseases that involve this area. Key points are being highlighted regarding the anesthetic management from the preoperative assessment until the inmmediate postoperative period.Finally we suggest an optimal anesthetic procedure based on literature and expert consensus in patients with these conditions.http://jaf.com.uy/2012/07/16/parador-al-aire-libre-en-pueblo-centenario/.

RESUMO O paciente oncológico apresenta um desafio intelectual e físico para o médico anestesiologista. Dentro da complexidade do tratamento, a cirurgia hepática, de via biliar, e pâncreas, requer considerações especiais. A epidemiologia, e o tipo de neoplasia especifica desta região do corpo, fazem com que os tratamentos cirúrgicos sejam extensos e radicais para conseguir uma maior sobrevida. O manejo anestésico visa a corrigir e diminuir as co-morbilidades do paciente previamente à cirurgia. O trans-anestésico obriga a um monitoramento invasivo para estabilizar hemodinamicamente o paciente e conseguir manter um adequado plano anestésico durante o procedimento. Nesta revisão continuada se expõe, uma atualizaçao da epidemiologia e o tipo de neoplasias que se envolvem nesta região. Recordam-se os pontos importantes do manejo anestésico desde a avaliação pré-operatório até o pós-operatório imediato. Por último se sugere um manejo anestésico ótimo fundamentado na literatura e no consenso de expertos em pacientes com estas condições.
