“…Development of hypoxaemia is therefore more likely. Applying CPAP with 100 per cent oxygen may help reduce the magnitude of hypoxaemia in those animals and this has been described in a dog with a DLT (Adami and others 2011). However, to the authors’ knowledge, the use of CPAP through an EZ-blocker has not been described in dogs though it was described as successful in a human case report (Calenda and others 2016).…”

“…Double-lumen tubes have been described to achieve lung separation and OLV in canine patients undergoing thoracoscopy in previous studies. Good control of ventilation to both lungs and easy access to the non-ventilated lung for CPAP administration are possible (Mayhew and others 2009, Adami and others 2011). However, there are a limited number of available sizes and they are designed for the human tracheobronchial tree.…”

This report documents the practical introduction of an EZ-blocker to achieve one-lung ventilation in two medium-sized dogs for video-assisted thoracoscopic pericardiectomy and right caudal lung lobectomy. Bronchoscopy was performed after blind introduction of the device through the endotracheal tube at the level of the tracheobronchial bifurcation. The EZ-blocker was successfully placed on the first attempt in the first case but initially remained trapped in the Murphy eye of the endotracheal tube in the second case, requiring repositioning. Surgical visibility was considered satisfactory when the left lung lobes were collapsed but not optimal when the right lung lobes had to be collapsed because the right cranial lung lobe could not be isolated for anatomical reasons. Both dogs recovered from anaesthesia uneventfully. Anaesthetic management with particular emphasis on the practical use of the EZ-blocker is reported. Placement of the EZ-blocker and challenges associated with right lung isolation are described.

Tension pneumothorax secondary to a grass awn in a dog

A 15-month-old female mixed breed dog was referred with a 3-day history of progressive dyspnoea and change in bark. Thoracic radiography showed pneumothorax, pneumomediastinum and atelectatic caudal lung lobes. Despite repeated thoracentesis and thoracostomy tube drainage, dyspnoea and cyanosis relapsed leading to the diagnosis of tension pneumothorax. An emergency exploratory thoracotomy showed a perforation on the ventral aspect of the right caudal lung lobe associated with a grass awn. Partial lobectomy was performed, followed by routine thoracotomy closure. The dog had an uneventful recovery and, on re-examination 2 and 6 months later, was normal.

“…Following CT the ETT was removed and the dog was bronchoscopically (OEV26IH 3.2mm flexible endoscope, Olympus, Australia) intubated with a left-DLT (Mallinckrodt 41F Left Broncho-Cath, Medtronic, Australia) as shown in Figure 1. The bronchial port was placed into the right mainstem bronchus, as previously described by Adami et al (2011). To check bronchial placement of the tube the bronchoscope was withdrawn from the bronchial tube lumen and placed into the tracheal tube lumen.…”

“…As a consequence, OLV induces substantial ventilation perfusion mismatching with a significant risk of hypoxemia (Karzai and Schwarzkopf, 2009). There are three techniques that can be used to perform OLV including selective intubation of a mainstem bronchus (endobronchial intubation), use of a doublelumen tube (DLT) (Mayhew and Friedberg, 2008;Adami et al, 2011) or use of a bronchial blocker (Cantwell et al, 2000;Lansdowne et al, 2005). Double lumen tubes consist of two tubes of different lengths connected longitudinally together (Fig.…”

One-lung ventilation with use of a double lumen tube in two dogs; when right might be wrong

One-lung ventilation (OLV) is an anaesthetic technique utilised for improved visualisation and access of the surgical field during thoracoscopy. The authors present two cases that underwent OLV with use of a double lumen tube (DLT). The first case was intubated with endoscopic guidance for bronchial port intubation of the right mainstem bronchus. This dog experienced prolonged periods of intraoperative hypoxemia. Upon case review, it was suspected intubation of the mainstem bronchus resulted in occlusion of the right cranial lung lobe. In the second case, the DLT was placed bronchoscopically into the left mainstem bronchus with the aid of computed tomography (CT). Excellent intraoperative oxygenation was achieved. When DLTs are used in dogs, their anatomical differences from humans make them susceptible to additional lung occlusion and pulmonary shunting. Computed tomography is recommended as a fundamental addition to bronchoscopy for correct tube placement.
