Barium Esophagogram

Tracheoesophageal fistula (TEF) is a rare congenital developmental anomaly, affecting 1 in 2500–3000 live births. The H-type TEF, consisting of a fistula between the trachea and a patent esophagus, is one of the rare anatomic subtypes, accounting for 4% of all TEFs. The presentation and perioperative management of neonates with H-type TEFs and all other TEFs are very similar to each other. Patients present with congenital heart disease and other defects and are prone to recurrent aspirations. A barium esophagogram or computed tomography of the chest is a common means to the diagnosis, and surgical repair is carried out through either a cervical approach or a right thoracotomy. During operation, anesthetic management is focused on preventing positive pressure ventilation through the fistula in an attempt to minimize gastric distension. For patients with H-type TEFs, because of the patent esophagus, symptoms are often less severe and nonspecific, resulting in subtle yet important differences in their diagnostic workup and management. This review will cover the finer details in the diagnosis and perioperative anesthetic management of TEF patients and clarify how H-type TEF distinguishes itself from the other anatomic subtypes.

Common Manifestation

Type-III tracheoesophageal fistula is the commonest type of fistula where upper pouch is blind and distal oesophageal pouch communicates with trachea. In this condition, gastric distension is a common manifestation which can be worsened by positive pressure ventilation. Pulmonary pathology may necessitate ventilation with high peak airway pressures which may rarely lead to gastric perforation with serious consequences. We are reporting such a case of gastric perforation during ventilatory management for fistula repair which needed surgical repair.

Noninvasive positive pressure ventilation (NIPPV) modalities have been proven to be effective in the setting of exacerbations of chronic obstructive pulmonary disease (COPD). Reported complications include pneumothorax, increased work of breathing, gastric distension and air embolism. This case demonstrates that patients with severe COPD on anticoagulant therapy are potentially at risk for the serious complication of combined lung barotrauma and hemorrhage while on acute NIPPV therapy. This is the first reported case of hemopneumothorax complicating NIPPV therapy.

Emphysematous Bulla

Anesthetic management for patients with a giant emphysematous bulla (GEB) is challenging. This case report describes a patient who developed 95% pulmonary compression by a GEB. A 14-Ga indwelling catheter was placed in the GEB before surgery to allow for slow re-expansion of the collapsed lung tissue. This prevented rupture of the GEB during anesthesia. Additionally, positive-pressure ventilation was performed to reduce the risk of re-expansion pulmonary edema. This respiratory management strategy may be beneficial for patients with a GEB who develop pulmonary dysfunction during thoracic surgery.

Transient Relaxation

Non-invasive intermittent positive pressure ventilation can lead to esophageal insufflations and in turn to gastric distension. The fact that the latter induces transient relaxation of the lower esophageal sphincter implies that it may increase gastroesophageal refluxes. We previously reported that nasal Pressure Support Ventilation (nPSV), contrary to nasal Neurally-Adjusted Ventilatory Assist (nNAVA), triggers active inspiratory laryngeal closure. This suggests that esophageal insufflations are more frequent in nPSV than in nNAVA. The objectives of the present study were to test the hypotheses that: i) gastroesophageal refluxes are increased during nPSV compared to both control condition and nNAVA; ii) esophageal insufflations occur more frequently during nPSV than nNAVA. Polysomnographic recordings and esophageal multichannel intraluminal impedance pHmetry were performed in nine chronically instrumented newborn lambs to study gastroesophageal refluxes, esophageal insufflations, states of alertness, laryngeal closure and respiration. Recordings were repeated without sedation in control condition, nPSV (15/4 cmH2O) and nNAVA (~ 15/4 cmH2O). The number of gastroesophageal refluxes recorded over six hours, expressed as median (interquartile range), decreased during both nPSV (1 (0, 3)) and nNAVA [1 (0, 3)] compared to control condition (5 (3, 10)), (p < 0.05). Meanwhile, the esophageal insufflation index did not differ between nPSV (40 (11, 61) h-1) and nNAVA (10 (9, 56) h-1) (p = 0.8). In conclusion, nPSV and nNAVA similarly inhibit gastroesophageal refluxes in healthy newborn lambs at pressures that do not lead to gastric distension. In addition, the occurrence of esophageal insufflations is not significantly different between nPSV and nNAVA. The strong inhibitory effect of nIPPV on gastroesophageal refluxes appears identical to that reported with nasal continuous positive airway pressure.

Tracheoesophageal fistula (TEF) and esophageal atresia (EA) is a congenital malformation occurring in 1:3,000 to 4,500 births. The condition presents specific challenges to the anesthesiologist in the perioperative period. The presence of a fistula means that infants born with TEF/EA are at risk of aspiration and positive-pressure ventilation may be hazardous. These babies often have coexistent problems associated with prematurity and low birth weight, and 50% have associated abnormalities, most commonly congenital cardiac malformations.

Fistula Surgery

The multifarious anaesthetic challenges associated with tracheo-oesophageal fistula surgery are difficult tracheal intubation, continuous air leakage during positive pressure ventilation, gastric distension, sharing of the airway with surgeons, intraoperative desaturation due to surgical retractors and maintaining anesthetic depth. These challenges are managed properly only when pathophysiology of the fistula is well understood. In this case report we present an anaesthetic management with a near miss situation during repair of tracheo-oesophageal fistula in a neonate. Intraoperatively, the patient’s oxygen saturation decreased which did not improve despite correcting all possible reasons. Before the worst could have occurred, we identified endotracheal tube blockage as the cause and changing the tube on time saved the neonate.

ABSTRACT Modern spirometry, like no other monitoring technique, allows insight into breath-to-breath respiratory mechanics. Spirometers continuously measure volume, airway pressure, and flow while calculating and continuously displaying respiratory system compliance and resistance in the form of loops. The aim of this case series is to show how observation of spirometric loops, similar to electrocardiogram or CO2 curve monitoring, can improve safety of anesthetic management in small animals. Spirometric monitoring cases described in this case series are based on use of the anaesthesia monitor Capnomac Ultima with a side stream spirometry sensor. The cases illustrate how recognition and understanding of spirometric loops allows for easy diagnosis of iatrogenic pneumothorax, incorrect ventilator settings, leaks in the system, kinked or partially obstructed endotracheal tube, and spontaneous breathing interfering with intermittent positive-pressure ventilation. The case series demonstrates the potential of spirometry to improve the quality and safety of anesthetic management, and, hence, its use can be recommended during intermittent positive-pressure ventilation and procedures in which interference with ventilation can be expected.

Although left- or right-sided pneumonectomy is tolerated by normal dogs, complications impacting the respiratory, cardiovascular, and gastrointestinal systems are not uncommon. Pneumonectomy in dogs results in secondary changes in the remaining lung, which include: decreased compliance and vital capacity; and increased pulmonary vascular resistance potentially leading to right ventricular hypertrophy. Such alterations make the anesthetic management of an animal with one lung particularly challenging. This report describes a dog with a history of left pneumonectomy due to Aspergillus fumigatus pneumonia 3 yr before presentation. The dog presented with a vaginal wall prolapse, and surgical resection of the protruding vaginal wall, ovariectomy, and prophylactic gastropexy were performed. Anesthesia was induced with midazolam, fentanyl, and propofol and was maintained with isoflurane using intermittent positive pressure ventilation and a constant rate infusion of fentanyl. Epidural anesthesia was also used. Recovery and postoperative management were uncomplicated. Intensive hemodynamic and respiratory monitoring and appropriate response and treatment of any detected abnormalities, taking into consideration the pathophysiologic alterations occurring in a pneumonectomized animal, are required for successful perianesthetic management.
