Medical errors are a leading cause of mortality in human medicine. In contrast, veterinary medicine rarely discussed, and there is little known about their nature frequency. This study aimed to evaluate the type severity medical reported three hospitals. The voluntary online incident reporting systems small animal teaching hospital, large multi-specialty practice were reviewed. Reports included if they entered between February 2015 March 2018, involved an pertaining patient safety....

The minimal anesthetic concentration (MAC) for isoflurane was determined during spontaneous ventilation in nine male Peking ducks (7 to 12 weeks of age; 3.0 ± 0.4 kg). While each bird awake, arterial blood collected analysis pH, PaCO 2 , and PaO . After anesthesia induced with oxygen, MAC a manner similar determinations mammals. Pulmonary dose‐response data were at 1 1.5 MAC. Anesthetic index (Al; an anesthetic‐induced apnea) calculated from that became apneic. 1.30 0.23% (mean SD). There...

Information on species differences in responses to inhalation anesthetics has been established a variety of mammalian and non-mammalian species, but comparable studies have not reported birds. The purpose this study was determine minimal anesthetic concentration cardiopulmonary concentration-response effects isoflurane Sandhill cranes. Six cranes were anesthetized with oxygen. Gases sampled through polyethylene tube inserted the distal end an endotracheal used for measurements concentrations...

The purpose of this study was to evaluate perioperative risk factors affecting neonatal survival after cesarean section. Data from 807 cesarean-derived litters (3,908 puppies) submitted by 109 practices in the United States and Canada. Survival rates immediately, two hours, seven days delivery were 92% (n=3,127), 87% (n=2,951), 80% (n=2,641), respectively, for puppies delivered section (n=3,410) 86% (n=409), 83% (n=366), 75% (n=283), born naturally (n=498). Maternal mortality rate 1% (n=9)....

Objective— To determine whether preoperative epidural administration of morphine and detomidine would decrease postoperative lameness after bilateral stifle arthroscopy in horses. Study design— Prospective clinical controlled study. Animals— Eight adult horses that had arthroscopic procedures, including drilling cartilage subchondral bone within the femoropatellar joints. Methods— Horses were randomly separated into 2 groups. Preoperatively, 4 administered a combination (0.2 mg/kg) (30...

Objective To describe dogs undergoing cesarean section in the United States and Canada, to determine perioperative management, calculate survival proportions. Design Multicenter prospective case series. Animals 3,908 puppies from 808 dams. Results Survival rates immediately, 2 hours, 7 days after delivery were 92, 87, 80%, respectively, for delivered by (n = 3,410) 86, 83, 75%, born naturally (498). For 614 of 807 (76%) litters, all alive. Maternal mortality rate was 1 % 9). Of 776...

SUMMARY To quantitate acetylpromazine-induced α-adrenergic receptor blockade, phenylephrine was infused into dogs. The amount of necessary to increase the mean arterial blood pressure ( map ) 50% above base line, with or without prior administration acetylpromazine, served quantify degree blockade. Seven dogs were anesthetized thiopental, maintained on halothane in oxygen, and mechanically ventilated. All infusions made through a catheter cephalic vein. Continuous recordings lead II ecg ....

Fentanyl is used in anesthetic protocols for swine, but there are no reports on its potency this species. This study measured the extent to which fentanyl reduces minimum alveolar concentration of isoflurane (MACISO) swine.Sixteen swine were randomly assigned four groups. For each group, baseline MACISO was determined, and three groups received two infusions as follows: 50 micrograms.kg-1.h-1 intravenously followed by 100 micrograms.kg-1.h-1, 200 or (n = 8 dosage). A loading dose preceded...

The objective of this prospective observational cohort study in free-ranging female white-tailed deer (Odocoileus virginianus) was to compare the physiologic effects two methods anesthetic drug administration: hand-injection Clover traps and remote injection by dart after ground-stalking. Six trapped 14 darted were injected with a median (minimum, maximum) 590 µg/kg butorphanol (401, 1070 µg/kg), plus 235 medetomidine (160, 429 µg/kg) intramuscularly. In trap, struggled when approached...
