Abstract:
Thoracoscopy was conducted to evaluate the port placement approaches for thoracoscopic examination in cattle. Twelve animals were randomly divided into two equal groups for thoracoscopy based on the placement of port, in group I animals dorsal port was created at 15 cm ventral to transverse process of thoracic vertebra in 9^th and 10^th ICS of right and left hemithorax and in group II placement of ventral port was created at 30-35 cm ventral to transverse process of thoracic vertebra ventrally in 7^th and 8^th intercostal space of right and left hemithorax. In all the animals. Standing sedation was achieved with Inj. butorphanol @ 0.05 mg/kg and port site anesthetized with Inj. 2% lignocaine HCl. Passive lung collapse was achieved by using teat cannula. A 57 cm, 0⁰ rigid telescopes with 10 mm diameter was used for thoracoscopy and all visible structures were identified and noted. At the end of the thoracoscopy the cranial port site wound was sutured by cruciate technique and suction was applied in caudal port to resolve the pneumothorax. The mean HR, SpO₂, AST, ALT, ALKP and serum creatinine were showed non-significant change between the groups. Whereas, the mean RR was highly significant and mean BUN showed significant increase between the groups. Postoperatively, animals were treated with broad spectrum antibiotic and analgesic for five days. Thoracoscopic examinations of the intrathoracic structures were visible and best achieved through the dorsal port at 9^th ICS and ventral port at 7^th ICS. Ventral port allowed closer examination of thoracic structures than achieved through dorsal port whereas, more discomfort to animal was observed at ventral port.
