Effect of classical music on light-plane anaesthesia and analgesia in dogs subjected to surgical nociceptive stimuli.

The objectives of this prospective, randomized, blinded, crossover, experimental study were to detect the potential anaesthetic- and analgesic-sparing effects of classical music provided to dogs undergoing skin surgery, and to investigate the role of substance P as an intraoperative pain indicator. Twenty dogs were included, each subjected to three different treatments: Chopin music, Mozart music and no music. They were premedicated with acepromazine, butorphanol and meloxicam and anaesthetized with propofol and isoflurane. Fentanyl was used as rescue analgesia. The anaesthetic depth was monitored by using the bispectral index along with standard anaesthetic monitoring, and autonomic nervous system responses were used to monitor the adequacy of analgesia. Furthermore, measurements of substance P serum concentration were carried out. Dogs exposed to music required less isoflurane and fentanyl. Furthermore, a statistically significant effect of time on substance P concentration was observed regardless of exposure to music, and there was a significant interaction effect between different timepoints and the type of acoustic stimulus. Classical music seems to have an isoflurane and fentanyl sparing effect on dogs undergoing minor surgery. Following surgical stimulation, the serum substance P concentration increases rapidly, and thus appears to be a potentially useful pain indicator.

Complete surgical excision versus Penrose drainage for the treatment of elbow hygroma in 19 dogs (1997 to 2014).

OBJECTIVES: To report results of surgical excision and Penrose drainage for the treatment of elbow hygromas in dogs. MATERIALS AND METHODS: Retrospective review of the clinical records of 19 dogs with elbow hygromas treated with Penrose drainage or surgical excision between 1997 and 2014. The data retrieved from the records included breed, gender, age, duration of clinical signs, weight, historical data, complete blood count and serum biochemistry, physical examination findings, diameter of the hygroma, cytology of needle aspirates, method of treatment, histological findings, postsurgical complications and their management and outcome. RESULTS: Twenty-one hygromas were treated in 19 dogs. Eleven were right-sided, six were left-sided and four were bilateral. First-line treatment was Penrose drain placement in 12 and complete surgical excision in nine. Bilateral hygromas were addressed simultaneously. Four of the 12 hygromas managed with Penrose drain recurred and one developed ulceration over the olecranon. Recurrent hygromas were treated by surgical excision. The ulceration was surgically excised and reconstructed with a thoracodorsal axial pattern flap. No further complications developed. All the dogs were clinically healthy after a median follow-up of 16 months. CLINICAL SIGNIFICANCE: Surgical excision of canine elbow hygroma is an effective technique that appears to have fewer postoperative complications than Penrose drain placement.

Dopamine-induced bradycardia in two dogs under isoflurane anaesthesia.

Dopamine is a commonly used positive inotropic agent for the treatment of hypotension in small animals. Two dogs that had undergone surgery, under isoflurane anaesthesia, developed a sudden and profound bradycardia when a dopamine infusion was administered. Bradycardia was attributed to the activation of the Bezold-Jarisch reflex, an inhibitory reflex, characterised by bradycardia and hypotension.

Postradical prostatectomy TRUS-guided anastomotic biopsy. Where do we stand today?

The issue of performing tissue sampling from the vesicourethral anastomotic area postradical prostatectomy (transrectal ultrasound-guided biopsy) after radical surgical treatment of local disease has failed, still remains controversial. We review a selection of articles that evaluate this procedure as well as newer diagnostic modalities and we discuss how this technique may have a position in our treatment dilemmas in cases with biochemical failure of undetermined origin.

The authors present their experience in the treatment of the Pierre Robin Syndrome in 32 cases. The purpose of this anatomical and clinical study is to guide and codify the surgical treatment of this malformation.

[Diagnosis of congenital tracheo-bronchial malformations in the newborn and infant]. / Le diagnostic des malformations congénitales trachéo-bronchiques du nouveau-né et du nourrisson.

Diagnosis endoscopy in congenital tracheo-bronchial abnormalities. High quality of anesthesia and efficiency of light sources and optical systems, now allow safe examination of upper respiratory tract and ability to give very precise informations in neonates and infants. Endoscopy now is then an essential procedure for diagnostic of congenital anomalies of respiratory tract. The necessary conditions for a safe examination and the necessity of complete exploration are exposed as well as endoscopic aspects of various congenital anomalies.
