Eyeworms of wild birds and new record of () (Nematoda: Spirurida).

The eyeworms of the subgenus infect orbital cavities, conjunctival sacs and lachrymal ducts of many wild birds, being able to cause conjunctivitis. In Brazil, at least 10 species of have been described. Here we present a brief review of cases of () and describe the infection of this parasite in , as a new host record.

Pulmonary hemodynamics and alveolar oxygenation in healthy dogs anesthetized with propofol or isoflurane during one-lung ventilation in a closed-thoracic experimental model.

OBJECTIVE To assess pulmonary hemodynamics and alveolar oxygenation in dogs anesthetized with propofol or isoflurane during one-lung ventilation (OLV) in a closed-thoracic experimental model. ANIMALS 6 healthy Beagles. PROCEDURES Dogs were anesthetized with each of 3 protocols (constant rate IV infusion of propofol [0.

Cardiopulmonary effects of reverse Trendelenburg position at 5° and 10° in sevoflurane-anesthetized steers.

Objective: To assess the cardiopulmonary effects caused by reverse Trendelenburg position (RTP) at 5° and 10° in sevoflurane-anesthetized yearling steers.

Study Design: Prospective, experimental study.

Animals: Eight Holstein steers aged (mean ± standard deviation) 12 ± 2 months and weighing 145 ± 26 kg.

Effects of dexmedetomidine combined with ropivacaine on sciatic and femoral nerve blockade in dogs.

Objective: To evaluate motor and sensory blockade of combining dexmedetomidine with ropivacaine, administered perineurally or systemically, for femoral and sciatic nerve blocks in conscious dogs.

Study Design: Randomized, controlled, experimental study.

Animals: Seven healthy Beagle dogs, aged 3.

Effects on indicators of tissue perfusion in dogs anesthetized with isoflurane at two multiples of the minimum alveolar concentration.

Objective: To investigate the effects of isoflurane anesthesia administered at 2 multiples of the minimum alveolar concentration (MAC) on tissue perfusion in dogs.

Animals: 8 healthy young adult Beagles.

Procedures: A randomized crossover design was used.

Continuous infusion of propofol in calves: bispectral index and hemodynamic effects.

Objective: To assess the bispectral index (BIS) and the hemodynamic effects of propofol administered by continuous infusion at different rates in calves.

Study Design: Experimental crossover study.

Animals: Eight intact male Dutch calves, aged 6-12 months and weighing 84-124 kg.

Comparison of anesthetic efficacy and adverse effects associated with peribulbar injection of ropivacaine performed with and without ultrasound guidance in dogs.

Objective: To compare the anesthetic efficacy and adverse effects associated with peribulbar injection of ropivacaine (1% solution) performed with and without ultrasound guidance (UG) in dogs.

Animals: 15 dogs without ophthalmologic abnormalities.

Procedures: Each dog was sedated and anesthetized.

Tumescent local anesthesia with ropivacaine in different concentrations in bitches undergoing mastectomy: plasma concentration and post-operative analgesia.

Objective: To compare two concentrations of ropivacaine administered for tumescent local anesthesia (TLA) in dogs undergoing mastectomy.

Study Design: Prospective randomized clinical study.

Animals: Seventeen bitches of various breeds, aged 12 ± 2 years and weighing 10 ± 6.

Electrocardiographic evaluation and degree of sedation with three doses of methadone in healthy dogs [corrected].

Objective: The present study aimed to investigate the influence of methadone on cardiorespiratory parameters, electrocardiogram and clinical sedation in dogs. Further possible side effects are reported.

Study Design: Prospective experimental cross-over study.
