Hemodynamic effects of an intravenous infusion of medetomidine at six different dose regimens in isoflurane-anesthetized dogs.

This study investigated the dose dependency of the hemodynamic effects of IV medetomidine (MED) constant-rate infusion (CRI) during isoflurane anesthesia. Twenty-four healthy beagles randomly received one of six MED CRI regimens. A loading dose of MED was administered IV at 0.

Post-anesthetic pulmonary edema in two horses.

CASE 1: A two-year old, 462 kg Standard bred horse was anesthetized for arthroscopy and castration. During anesthesia, hyperemia of the mucosal membranes and urticaria were noticed. During 5 hours of anesthesia subcutaneous edema of the eyelids and neck region developed.

The use of lingual venous blood to determine the acid-base and blood-gas status of dogs under anesthesia.

Objective: To assess the suitability of lingual venous blood (LBG) as an alternative to arterial blood (ABG) samples in determining acid-base balance and blood-gas status in dogs anesthetized for elective procedures and with medetomidine and isoflurane administration under experimental conditions.

Study Design: Prospective, randomized clinical and experimental study.

Animals: Clinical population of 18 ASA I/II dogs for elective surgery and five healthy Beagles (3 females and 2 males) for the experimental study.

Survey of utilization of medetomidine and atipamezole in private veterinary practice in Quebec in 2002.

This survey evaluates early perceptions about the use of medetomidine and atipamezole among veterinary practitioners in Quebec in 2002. Response rate was 23.5%; 71.

Evaluation of epidural administration of morphine or morphine and bupivacaine for postoperative analgesia after premedication with an opioid analgesic and orthopedic surgery in dogs.

Objective: To evaluate the analgesic efficacy of epidural administration of morphine or a morphine-bupivacaine combination administered before orthopedic surgery in dogs that received opioid premedication.

Design: Prospective, randomized, blinded, clinical study.

Animals: 36 healthy adult dogs that underwent elective orthopedic surgery on a pelvic limb.

Sudden cardiac death associated with occult hypertrophic cardiomyopathy in a dog under anesthesia.

A 6-year-old, 3.0 kg, neutered female, Yorkshire terrier was referred for orthopedic surgery. Cardiac arrest followed unsuccessful treatment of bradycardia and systemic arterial hypotension under general anesthesia.

Results of preemptive epidural administration of morphine with or without bupivacaine in dogs and cats undergoing surgery: 265 cases (1997-1999).

Objective: To determine prevalence of adverse effects associated with epidural administration of morphine with or without bupivacaine in dogs and cats undergoing surgery and evaluate effects of epidural administration of morphine on postoperative pain severity.

Design: Retrospective study.

Animals: 242 dogs and 23 cats.
