ABSTRACT
Goal: Thoracic surgery usually used for anesthesia double lumen endotracheal tubes, then ventilatedone lung.Methods: The clinical records of the 160 cases patients who had double-lumen endotracheal tubes toplace in National Cancer Center of Mongolia (this structure starts from the inferior part of the larynxin the neck, opposite the 6th cervical vertebra, to the intervertebral disc between Th4-5 vertebrae inthe thorax, where it divides at the carina into the right and left bronchi). Inpatients during one lunganesthesia done 2012- and 2014 were reviewed. All cases were performed high Level thoracic epiduralcatheterization and put double lumen tube for jugularinternal vena. Double-lumen endotracheal tubesare not meant for postoperative ventilation. In addition, because of their significantly larger size andstiffness, they have a higher propensity for trauma after insertion, which may result in postoperativehoarseness or vocal cord lesions.Results: We are reporting 2012- 2014 anesthesia department at National Cancer Center. In our studyinvolved all 160 open thoracic surgery cases with DLT. In study had anesthesia tidal volume7.77+1.07ml/kg, one lung volume 5.87+0.46 ml/kg, the women DLT size 33.43+7.25Fr, deep 27.68+2.47 cm, manDLT size 37.09+7.69cm, deep 28.43+2.6 cm. During anesthesia monitored averageSaO2-95%+1.07,in analyzed arterial blood average SpO2- 92.605 %+5.69 (p<0.032).Conclusion: One lung anesthesia separating two lungs by double lumen tube (DLT) – the advantagesof the method are allowing surgeons to operate safely in collapsed side of lung; there are a few reportsof airway damages. The bronchoscopy procedure is in need to use during the alloperations. Other typesof separation tube are required to be (especially in children) introduced.
ABSTRACT
Aims and Objectives: The risk assessment of epidural hematoma due to catheter placement in patients undergoing cardiac surgery is essential since its benefits have to be weighed against risks, such as the risk of paraplegia. We determined the risk of the catheter-related epidural hematoma in cardiac surgery based on the cases reported in the literature up to September 2012. Materials and Methods: We included all reported cases of epidural catheter placement for cardiac surgery in web and in literature from 1966 to September 2012. Risks of other medical and non-medical activities were retrieved from recent reviews or national statistical reports. Results: Based on our analysis the risk of catheter-related epidural hematoma is 1 in 5493 with a 95% confidence interval (CI) of 1/970-1/31114. The risk of catheter-related epidural hematoma in cardiac surgery is similar to the risk in the general surgery population at 1 in 6,628 (95% CI 1/1,170-1/37,552). Conclusions: The present risk calculation does not justify not offering epidural analgesia as part of a multimodal analgesia protocol in cardiac surgery.

Objetivo . Describir nuestra experiencia en el manejo anestesiológico de las pleuroscopías. Pacientes y métodos. Se consultó nuestra base de datos en un período comprendido entre julio de 2000 y julio de 2002. Revisamos 70 procedimientos de pleuroscopías con cirugía videoasistida (CVA), realizados con anestesia general e intubación con sonda de doble luz para ventilación unipulmonar. Resultados. Las indicaciones más frecuentes fueron derrames pleurales y neumotórax , los procedimientos más frecuentes fueron pleurodesis y biopsias. El porcentaje de reconversión de la técnica fue de 5.7%, en su mayoría por dificultades técnicas. No hubo hemorragias importantes ni muertes atribuibles a la técnica. De las complicaciones no quirúrgicas 4 pacientes presentaron broncoespasmo que retrocedió con tratamiento habitual y 5 presentaron hipoxemia que obligó a suspender transitoriamente la ventilación unipulmonar. En el postoperatorio un paciente presentó un cuadro de edema pulmonar con buena evolución en 24 horas. Los pacientes coordinados para aerostasis presentaron menos enfermedades asociadas y menor ASA, a diferencias de los que presentaban masas y tumores pulmonares. En 69 pacientes se logró una adecuada ventilación unipulmonar. La complicación más frecuente fue el desplazamiento distal de la sonda. El número de otras complicaciones fue bajo, fácilmente controlable y atribuible al terreno del paciente y al tipo de sonda utilizado. Conclusión. Las pleuroscopías realizadas con anestesia general y ventilación unipulmonar son procedimientos seguros, con complicaciones esperables y con buena respuesta al tratamiento. El diagnóstico quirúrgico y el tipo de procedimiento indicado, son datos importantes para evaluar el riesgo de enfermedades asociadas y de complicaciones.
This article describes the authors´experience in the anesthetic management of pleuroscopies in a General Hospital in Montevideo, Uruguay. Patients and Methods Data were collected from Anesthesia Departament Database corresponding to a period of two years from july 2000 to july 2002. Seventy pleuroscopies were reviewed. All patients underwent general anesthesia and in all cases double lumen tubes were used for unipulmonar ventilation. Results Empyema and neumothorax were the most frequent preoperative diagnoses. Pleurodesis and pleural biopsies were the most frequently used procedures. Surgical technique was converted in 5.7% of all cases due to technical difficulties. No significant bleeding or deaths occurred during surgery or in the postoperative period in these serie of patients. Other incidents related to anesthesia were bronchospasm (4 patients, all of them fully recovered after usual treatment) and hypoxia (5 patients who required discontinuation of unipulmonar ventilation). In the postoperative period one patient suffered from pulmonar edema requiring admission in an intensive care unit. After 24 hours the patient fully recovered and was succesfully discharged from that Unit. All patients who underwent aerostatic procedures were in the preoperative period, in better physical conditions (lower ASA score) than those with lung tumors. Unipulmonar ventilation was succesfully performed in 60 of 70 total patients. Distal double lumen tube malposition was the most frequent complication. Other incidents were rare and in all cases easily solved. In most cases they were related to patients´ previous physical status or to characteristics or quality of double lumen tubes utilized. Conclusions In our experience Pleuroscopies under General Anesthesia and unipulmonar ventilation are safe procedures with well known complications and good response to usual treatment. Preoperative diagnose and procedure performed, are important data in order to assess the risk of associated illnesses and postoperative complications.
ABSTRACT
Among patients scheduled for elective surgery at the Kyung Hee University Hospital, 15 patients undergoing open thoracotomy were selected. Two different ventilatory modes were employed and compared to the one-lung ventilation(control). First, 10 cmH2O of continuous positive airway pressure was applied to the unventilated lung while patients were under one lung ventilation with 50% oxygen(CPAP 10 cmH2O). Second, 10 cmH2O of positive end expiratory pressure to the ventilated lung and 10 cmH2O of continuous positive airway pressure to the unventilated lung were applied while patients were under one lung ventilation with 50% oxygen(CPAP/PEEP). Arterial oxygen tension, alveolar-arterial oxygen difference (A-aDO2) and intrapulmonary shunt fraction of two different ventilatory modes were observed and compared to control group, and CPAP/PEEP group to CPAP 10 cmHO group. The RESULTs were as followed: 1) Mean PaO2 in CPAP 10 cmH2O and CPAP/PEEP were 138+/-42 mmHg and 177+/-44 mmHg, respectively, and were significantly increased as compared to 100+/-29 mmHg of control group(P<0.05). Comparing the PaO2 of CPAP 10 cmH2O and CPAP/PEEP, there was statistically significant increase in CPAP/PEEP(P<0.05). 2) A-aDO2 in CPAP 10 cmH2O and CPAP/PEEP were 175+/-43 mmHg and 131+42 mmHg, respectively, and were significantly decreased as compared to 213+/-32 mmHg of control group(P<0.05). Shunt percentages(Qsp/QT) were measured as 23.7+/-5.8% in control group, 18.3+/-6.0% in CPAP 10 cmH2O, 13.0+/-4.3% in CPAP/PEEP. Shunt percentages of CPAP 10 cmH2O and CPAP/PEEP were decreased significantly as compared to the control group(P<0.05). Comparing the A-a DO2 and the shunt percentages of CPAP 10 cmH2O and CPAP/PEEP, there was statistically significant decrease in CPAP/PEEP(P<0.05). Based on the above RESULTs, the application of appropriate continuous positive airway pressure to the unventilated lung and 10 cmH2O of positive end expiratory pressure to the ventilated lung during one lung ventilation is thought to be more effective than only continuous positive airway pressure to the unventilated lung in preventing hypoxemia.

Among patients scheduled for elective thoracic surgery at the Medical Center of Kyung Hee University, 15 patients undergoing lobectomy or pneumonectomy were selected. Three different ventilatory modes were employed and compared to the two-lung ventilation with 50% oxygen (control). First, patients were ventilated with 50% oxygen and left the unventilated lung to deflate during one lung ventilation (test 1). Second, continuous positive airway pressure (CPAP) of 10 cmH2O was applied to the ventilated lung while patients were under one lung ventilation with 50% oxygen (test 2). Lastly, patients were ventilated with 100% oxygen and unventilated lung was left to deflate during one lung ventilation (test 3). PaO2, A-aDO2 and Qsp/QT of three different ventilatory modes were observed and compared to that of control, and that of test 2 to test 1. The results were as followed: 1) Mean PaO2 in test 1 and test 2 were 98+/-24.0 mmHg and 126+/-34.8 mmHg, respectively and were significantly decresed as compared to the PaO2 of control, 234+/-21.4 mmHg. Comparing the PaO2 of test 1 and test 2, there was statistically significant increase in test 2 (P<0.01). 2) Comparing with A-aDO2 of control (68+/-22.5 mmHg), A-aDO2 in both test 1 and test 2 were significantly increased to 210+/-24.3 mmHg and 184+/-33.4 mmHg, respectively. there was significantly decreased in test 2 as compared to test 1 (P<0.01). 3) Shunt percentages (Qsp/QT) were measured as 8.3+/-2.3% in control, 25.4+/- 6.7% in test 1, 19.8+/-3.2% in test 2. Shunt percentages of test 1 and test 2 were increased significantly as compared to the control. Comparing the shunt percentages of test 1 and test 2, there was decreased in test 2 (P<0.01). Based on the above results, the application of appropriate CPAP to the unventilated lung during one lung ventilation is thought to be very effective in preventing hypoxemia. But, vigorous and meticulous monitoring, surveilance of patients and one lung ventilation with 100% oxygen are essential depending on the conditions of ventilated lung and long duration of one lung ventilation.
