“…This finding was found to support the opinion that mechanical ventilation sustained lung function and encouraged return of function of atelectatic alveoli that had occurred due to general anaesthesia 3,6,7 . The authors also thought that the ventilation provided during anaesthesia, at the tidal volume determined according to the bodyweight of patients, was effective in this increase in pulse oximeter data.…”

SummarySpontaneous ventilation during general anaesthesia leads to respiratory depression and atelectasis. Mechanical ventilation increases tidal volume and eliminates atelectasis. The study material consisted of a total of 20 dogs of different breed, age and gender. Dogs were divided into two groups, consisted of 10 dogs. The first group was established as the spontaneous ventilation (SV) group, while the second group was the mechanical ventilation (MV) group. For induction of anaesthesia, propofol was administered to both groups via intravenous injection at a dose of 6 mg/kg. Blood samples were collected from all dogs in 5 minutes after propofol administration. This period was determined as Minute 0 (T 0 ). In both groups, inhalation anaesthesia was continued with isoflurane. Venous blood samples were collected from dogs in the SV and MV groups at 15 (T 15 ), 30 (T 30 ) and 60 (T 60 ) minutes. Heart rate, respiratory rate, SpO 2 , body temperature and blood gases were monitored. Statistical evaluation of the study was carried out using the Repeated Measures Analysis of Variance method. The results obtained showed that there was no statistically significant difference between the SV and MV groups regarding the examined parameters. However, in the assessments within the group, results obtained from the dogs in the MV group were more reliable from the point of view of the patients remaining stable throughout anaesthesia. Keywords: Spontaneous ventilation, Mechanical ventilation, Blood gases, Dog Köpeklerde Genel Anestezi Sürecinde Spontan ve Mekanik Ventilasyonun Kan Gazları Üzerine Etkilerinin Karşılaştırılması ÖzetGenel anestezide spontan ventilasyon, solunumun baskılanmasına ve atelektaziye yol açar. Mekanik ventilasyon tidal volümü artırır ve atelektaziyi giderir. Çalışma materyalini, farklı ırk, yaş ve cinsiyetteki toplam 20 köpek oluşturdu. Olgular, her grupta 10 köpek olacak şekilde 2'ye ayrıldı. İlk grup spontan ventilasyon (SV), ikinci grup mekanik ventilasyon (MV) grubu olarak belirlendi. Anestezi indüksiyonunda her iki gruba, propofol 6 mg/kg'dan intravenöz enjeksiyonla verildi. Tüm köpeklerden, propofol enjeksiyonunu takip eden 5. dakikada kan örnekleri alındı. Bu süre 0. dakika (T 0 ) olarak değerlendirildi. Her iki grubun inhalasyon anestezisi izofloranla sürdürüldü. SV ve MV grubundaki olgulardan 15. dakika (T 15 ), 30. dakika (T 30 ) ve 60. dakika (T 60 )'larda venöz kan örnekleri alındı. Kalp atım sayısı, solunum sayısı, SpO 2 , vücut ısısı ve kan gazları monitörize edildi. Çalışmanın istatistiki değerlendirmesi Tekrarlı Ölçüm Varyans Analizi metodu ile yapıldı. Elde edilen bulgular, incelenen parametreler yönünden SV ve MV grupları arasında istatistiki anlamda önemli bir fark olmadığını gösterdi. Ancak grup içi değerlendirmelerde, MV grubundaki köpeklerden elde edilen sonuçların, hastaların anestezi süresince stabil kalmaları açısından daha güvenilir olduğu sonucuna ulaşıldı.

“…57 In 14 other cases, the mean duration of ventilation was 4.5 days, and 9 dogs had a favorable outcome (ie, regained the ability to walk). 54 In this case series, the 2 dogs that lacked pain sensation did not recover. Hypoventilation will appear before loss of sensation; therefore, in any tetraplegic animal it is crucial to search for signs of respiratory dysfunction (poor quality of chest movements, hypo-/hyperventilation, measurements of carbon dioxide pressure and oxygen saturation).…”

“…54 These dogs were commonly affected by a lesion within the C2-C4 segments (which differs from the aforementioned experimental observations) and underwent a decompressive laminectomy. 54 It is possible that clinical lesions extend over several spinal cord segments, therefore involving segments below C5 when the lesion epicenter is around C2-C4. In dogs with cervical IVDH a similar occurrence of neurogenic hypoventilation was recently found to affect 2 of 35 tetraplegic cases.…”

“…This gives rise to the phrenic nerve through segments 5 to 7 of the cervical spinal cord. The reticulospinal tracts also give rise to the neurons that innervate the intercostal muscles via the segmental intercostal nerves [3]. The blood pH remained within almost normal levels prior to surgery, although the PaCO 2 was clearly increased.…”

Secondary Chronic Respiratory Acidosis in a Dog Following the Cervical Cord Compression by an Intradural Glioma.

ABSTRACT. An intradural tumor in the upper cervical region was found in a dog with quadriparesis and chronic respiratory acidosis. Surgical removal of the tumor in the atlas and intraoperative radiotherapy were attempted. The tumor was histologically diagnosed as a neural glioma. A preoperative acid-base disturbance was dramatically improved after surgery. The clinical changes appeared in this case suggest that compression of the spinal cord at this region may cause paralysis of the respiratory muscles and secondarily result in chronic respiratory acidosis following the respiratory insufficiency.

Ventilatory failure, ventilator management, and outcome in dogs with cervical spinal disorders: 14 cases (1991–1999)

Abstract: Results suggest that a small percentage of dogs with cervical spinal disorders may require perioperative ventilatory support. With prolonged PPV and aggressive management, a good outcome may be achieved in dogs similar to those described in the present study.
