While insertion of a double lumen tube (DLT) is the standard technique, the use of bronchial blockers (BB) is becoming more common.</p><p id="par0010" class="elsevierStylePara elsevierViewall">A common problem during one-lung ventilation (OLV) is hypoxaemia, particularly in patients with reduced pulmonary function reserve. Approximately 5–10% of patients who survive lobectomy or pneumonectomy due to lung cancer develop secondary lung cancer within 5 years that often requires reintervention, sometimes involving resection of the contralateral lung. These patients cannot usually tolerate OLV and develop hypoxaemia. Several techniques are available to address this situation.</p><p id="par0015" class="elsevierStylePara elsevierViewall">First, lobe-selective bronchial blockade can be achieved by inserting a BB through a DLT or single lumen tube.<a class="elsevierStyleCrossRefs" href="#bib0020"><span class="elsevierStyleSup">1,2</span></a> However, BBs can only be used when a fiberoptic bronchoscope wide enough to accommodate the device is available, and the technique requires extensive training and excellent knowledge of the anatomy of the bronchial tree. BBs are also more expensive than DLTs, take longer to collapse the lung, and sometimes need to be repositioned several times during surgery. For these reasons, they are not available in all hospitals.</p><p id="par0020" class="elsevierStylePara elsevierViewall">A second option is the administration of continuous positive airway pressure through the blocked branch of the DLT. This, however, can obstruct video-assisted thoracoscopy (VATS), and usually requires reconversion to thoracotomy.</p><p id="par0025" class="elsevierStylePara elsevierViewall">The third option is to ventilate the spared lobe of the operated lung in order to increase the surface area available for gas exchange while minimising interference with the surgical field. This allows lung resection to be performed using VATS. To achieve this, we have devised a novel technique that involves administering O<span class="elsevierStyleInf">2</span> in the target lobe via the working channel of a flexible fibreoptic bronchoscope connected to a source of O<span class="elsevierStyleInf">2</span>.

Before anaesthesia induction, the patient was preoxygenated for 5<span class="elsevierStyleHsp" style=""></span>min with FiO<span class="elsevierStyleInf">2</span> of 1, which increase SpO<span class="elsevierStyleInf">2</span> to 99%. After this, anaesthesia was induced with propofol (50<span class="elsevierStyleHsp" style=""></span>mg<span class="elsevierStyleHsp" style=""></span>+<span class="elsevierStyleHsp" style=""></span>125<span class="elsevierStyleHsp" style=""></span>mg), fentanyl (100<span class="elsevierStyleHsp" style=""></span>mcg), rocuronium (10<span class="elsevierStyleHsp" style=""></span>mg), and succinylcholine (100<span class="elsevierStyleHsp" style=""></span>mg). Face mask ventilation (Han grade III) was difficult, but intubation (Cormack–Lehane grade I) with a left 39 Fr DLT was easy. A dual catheter was placed in the right subclavian vein, the left radial artery, and a second 16G-gauge peripheral line was placed in the right arm. In addition, a right paravertebral catheter was placed at the level of T6. Anaesthesia was maintained with boluses of desflurane, remifentanil and rocuronium.</p><p id="par0055" class="elsevierStylePara elsevierViewall">OLV was started with SatO<span class="elsevierStyleInf">2</span> at 99% and EtCO<span class="elsevierStyleInf">2</span> at 35<span class="elsevierStyleHsp" style=""></span>mmHg in bipulmonary ventilation (BPV). Five minutes later, SatO<span class="elsevierStyleInf">2</span> fell to 84%, forcing us to return to BPV with FiO<span class="elsevierStyleInf">2</span> of 1. Pulmonary recruitment manoeuvres were performed, which brought SatO<span class="elsevierStyleInf">2</span> up to 100% with FiO<span class="elsevierStyleInf">2</span> of 0.8. After the third attempt of OLV with FiO<span class="elsevierStyleInf">2</span> of 1, it was clear that the patient would not tolerate OLV. Faced with this situation, we considered several options. On the one hand, a BB in the RML. This was ruled out, as there were no BBs available in our hospital. As a second option, we considered administering continuous positive airway pressure through the tracheal portion of the DLT. This is the most commonly used technique in our service in patients that do not tolerate OLV; however, it can obstruct VATS, and usually requires a thoracotomy. The third option, and the one we ultimately chose, was to use the right upper lobe (RUL) to increase the gas exchange surface area while minimising interference with the surgical field. This allowed us to continue with VATS lobectomy. To achieve this, we tested a novel technique that involves administering O<span class="elsevierStyleInf">2</span> in the RUL lobe via the working channel of a flexible fibreoptic bronchoscope inserted in the RUL bronchus and connected to a source of O<span class="elsevierStyleInf">2</span>. Gas was delivered at a flow rate of between 2 and 3<span class="elsevierStyleHsp" style=""></span>L (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). With the bronchoscope in place, the patient's SpO<span class="elsevierStyleInf">2</span> of 90%, increased to 92% after starting delivery of O<span class="elsevierStyleInf">2</span> through the working channel. During the rest of the intervention, while maintaining OLV, SpO<span class="elsevierStyleInf">2</span> ranged from 92% to 93% without interfering at any time with the VATS RML resection plus lymphadenectomy, and without the need to reposition the bronchoscope. The rest of the surgery was uneventful.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia></span><span id="sec0015" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0035">Discussion</span><p id="par0060" class="elsevierStylePara elsevierViewall">An increasing number of patients require further thoracic surgery after undergoing lobectomy. Considering that lung function is reduced by around 23.8% after left upper lobectomy,<a class="elsevierStyleCrossRef" href="#bib0030"><span class="elsevierStyleSup">3</span></a> it stands to reason that a patient requiring pulmonary resection in the contralateral lung will develope hypoxaemia during OLV. In addition, overloading the ventilated lung that already lost volume after the first surgery increases the risk of baro or volotrauma, and may trigger acute lung injury.</p><p id="par0065" class="elsevierStylePara elsevierViewall">There a several options available to prevent hypoxaemia in these patients or others with advanced lung disease that requires pulmonary resection surgery. However, the best strategy will depend on the availability of certain airway devices, or the experience of the anaesthesiologist.</p><p id="par0070" class="elsevierStylePara elsevierViewall">A useful technique is lobe-selective bronchial blockade using a BB, provided these devices are available, the operator is skilled in the use of a fibreoptic bronchoscope, and has a good understanding of bronchial anatomy. However, BBs often become dislodged, usually as a result of surgical manoeuvres, and lung deflation takes longer, since resistance to outflow/aspiration is much greater than with a DLT. If, for example, the operated lung needs to be ventilated to check the safety of the bronchial sutures and then re-blocked, it is sometimes necessary to reposition the BB and wait for lung deflation again. This manoeuvre is much faster and simpler with a DLT.</p><p id="par0075" class="elsevierStylePara elsevierViewall">To overcome these obstacles, we propose this novel one-lung oxygenation technique in which oxygen is delivered to one of the spared lobes of the operated lung. To achieve this, the fibreoptic bronchoscope is introduced into the spared lobe and low-flow oxygen is administered through the working channel.</p><p id="par0080" class="elsevierStylePara elsevierViewall">We believe that this technique has several advantages over BBs, including faster lung collapse, since a DLT is used; greater aspiration power and large calibre aspiration tubes, given the size of the DLT – a particular advantage in patients with secretions and in case of intrapulmonary bleeding; intralobar placement of the fibreoptic bronchoscope is technically easier than placement of the BB, especially in certain positions such as URL; the bronchoscope is less likely to migrate and need repositioning than the BB because it is not placed in the operated lobe; and finally, the flow of oxygen through the working channel of the fibreoptic bronchoscope can be varied according to the needs of the patient.</p><p id="par0085" class="elsevierStylePara elsevierViewall">However, there are several factors that need further investigation in order to optimise their benefits and detect potential risks. These include the potential for the bronchoscope to cause injury in the bronchial tree if left in place for a prolonged period of time; the factors that can lead to the clinical or technical failure of the procedure; the maximum oxygen flow that can be used without causing injury distal to gas administration; and determining which lobe is best to use in the case of right lobe resections.</p><p id="par0090" class="elsevierStylePara elsevierViewall">We believe this single-lobe oxygen therapy technique to be satisfactory, since it did not interfere with the surgical field, and allowed us to perform VATS lobectomy (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>). Furthermore, it was not necessary to interrupt surgery at any time to reposition the bronchoscope, and we did not observe any perioperative complications related to the technique. We believe, therefore, that this may be a simple alternative to traditional DLT lung isolation in patients with low functional reserve.</p><elsevierMultimedia ident="fig0010"></elsevierMultimedia></span><span id="sec0020" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0040">Conflicts of interest</span><p id="par0095" class="elsevierStylePara elsevierViewall">The authors declare that they have no conflicts of interest.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:9 [ 0 => array:3 [ "identificador" => "xres1092849" "titulo" => "Abstract" "secciones" => array:1 [ 0 => array:1 [ "identificador" => "abst0005" ] ] ] 1 => array:2 [ "identificador" => "xpalclavsec1035705" "titulo" => "Keywords" ] 2 => array:3 [ "identificador" => "xres1092850" "titulo" => "Resumen" "secciones" => array:1 [ 0 => array:1 [ "identificador" => "abst0010" ] ] ] 3 => array:2 [ "identificador" => "xpalclavsec1035706" "titulo" => "Palabras clave" ] 4 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 5 => array:2 [ "identificador" => "sec0010" "titulo" => "Case report" ] 6 => array:2 [ "identificador" => "sec0015" "titulo" => "Discussion" ] 7 => array:2 [ "identificador" => "sec0020" "titulo" => "Conflicts of interest" ] 8 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2017-11-26" "fechaAceptado" => "2018-02-05" "PalabrasClave" => array:2 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec1035705" "palabras" => array:4 [ 0 => "Unilobar oxygenation" 1 => "Oxygenation with bronchofibroscopy" 2 => "Lung resection surgery" 3 => "One lung ventilation" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec1035706" "palabras" => array:4 [ 0 => "Oxigenación unilobar" 1 => "Oxigenación con fibrobroncoscopio" 2 => "Cirugía de resección pulmonar" 3 => "Ventilación unipulmonar" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:2 [ "titulo" => "Abstract" "resumen" => "<span id="abst0005" class="elsevierStyleSection elsevierViewall"><p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">Lung isolation using one-lung ventilation is common during thoracic surgery procedures, as it allows proper visualisation and manipulation of the lung to be operated on. Selective lobar blockade has been described in patients that do not tolerate one-lung ventilation, and is usually achieved using endobronchial blockers.
