“…Although endotracheal intubation using a plastic guide wire seems to be time-consuming, it was found that its use shortened the duration of the procedure, improved the ease of the procedure and reduced the risks of the procedure.

“…Successful endotracheal intubation at the first attempt is very important, because it reduces the risk of injury to the laryngeal mucosa [ 4 ]. Even when the intubation is properly performed and successful at the first attempt using the standard orotracheal method, it has been reported that laryngotracheal damage, such as ulceration of the respiratory mucosa that is in contact with the tube, perichondritis, proliferation of granulation tissue and, eventually, formation of scar tissue and stenosis may still occur [ 3 , 6 ].…”

“…The successful endotracheal intubation of pigs using the standard orotracheal method is challenging and technically difficult in comparison to human and other experimental animals [ 1 , 4 ], because of the pig’s oral anatomy and the presence of excess tissue in the oropharyngeal region. Specifically, visibility of the laryngeal opening is impeded, because of its long snout, the thick fleshy base of its tongue, the angle of the elevation of the soft palate and the descent of the epiglottis [ 9 ].…”

The successful endotracheal intubation of pigs using the standard orotracheal method is challenging and technically difficult, because of the pig’s oral anatomy and the presence of excess tissue in the oropharyngeal region. Hence, the operator, who is usually an anesthetist, requires extensive training in order to successfully perform the procedure in pigs. In this report, we describe a safe and quick method of successful endotracheal intubation in the pig using an 80-cm blunt-tipped plastic vascular catheter, when the pig is placed in ventral recumbency. Specifically, the use of this plastic guide wire shortened the duration of the procedure and reduced the risks of the procedure. Since the use of the guide wire also improves the ease of the procedure, its use will also enable inexperienced operators to perform successful first-time endotracheal intubation of pigs without causing injury.

“…Pigs have a small larynx diameter compared to other animals of similar weight. Endotracheal intubation is hampered by poor visualization of the larynx due to the narrow mouth opening, long distance from the snout to the larynx, its anatomical features and protective reflexes (Hartmann et al, 1971, Murison, 2011. For safe anaesthesia, it is important that the intubation of a pig be successful at the first attempt, as subsequent attempts can cause very serious respiratory damage and may be lethal (Oshodi et al, 2011, Steinbacher et al, 2012.…”

Background: Animal intubation is necessary in painful surgery procedures in order to maintain general anaesthesia and analgesia. In swine, orotracheal intubation is difficult or impossible; all possible measures to improve it need to be explored. Methods: Two groups of a total of 20 clinically healthy local mixed breed (Sus scrofa domesticus) premedicated swine underwent intubation. The animals were randomly divided into two groups, one using atropine sulphate (A) and one using saline solution (N), prior to endotracheal intubation. Premedication started with intramuscular injection of xylazine, ketamine and fentanyl. Intubation was performed after induction with thiopental sodium administered intravenously with atropine sulphate or saline solution. Larynxes were photographed and filmed and coded images and videos were sent to investigators for evaluation. Result: In this study, a negative effect of atropine sulphate on the laryngeal visibility, opening and accessibility in local mixed breed anesthetized pigs was identified.

Ventral recumbency is crucial for fast and safe orotracheal intubation in laboratory swine

et al. 2009

The aim of this study was to find the fastest, easiest and safest method of achieving orotracheal intubation for general anaesthesia in laboratory pigs. Twenty-one Yorkshire Â Landrace crossbreed male castrated pigs (32.9 + 4.8 kg) were investigated. Dorsal and ventral recumbency are the alternatives most frequently described for animal positioning during intubation procedures. Based on standardized induction of general anaesthesia using pentobarbital and remifentanil, the dorsoventral and ventrodorsal positions were compared with regard to the time needed, changes in oxygenation and circulatory response. Positioning was found to be crucial for fast orotracheal intubation. The time required for safe intubation is significantly shorter with the ventrodorsal position (17.3 s) in comparison with the dorsoventral position (58.4 s; P , 0.001). Hypoxia did not occur in either group. A significant drop in systolic blood pressure was observed in both groups. Diastolic and mean arterial pressures were not influenced by intubation. A significant increase in heart rate was observed in pigs intubated in ventral recumbency, but not after intubation in the dorsal position. Preoxygenation before intubation is vitally important for preventing hypoxia. With regard to clinical practice, the haemodynamic changes observed in this investigation do not appear to be relevant, as the mean arterial pressure was not altered and heart rates only increased moderately. It may be concluded that the ventrodorsal position can be recommended for orotracheal intubation in pigs as the first choice for providing a smooth and fast airway.
