PHYSIOLOGICAL AND ANESTHETIC EFFECTS OF HAND INJECTION VERSUS DARTING TO INDUCE ANESTHESIA IN CHIMPANZEES ().

Great ape anesthesia is reported to carry a significant risk. Therefore, techniques aiming to reduce stress and increase welfare, such as hand injection of anesthesia induction agents, have received considerable attention in zoo, laboratory, and captive wildlife environments. However, there is little evidence to support the superiority of such techniques.

Canine and feline blood transfusions: controversies and recent advances in administration practices.

Objectives: To discuss and review blood transfusion practices in dogs and cats including collection and storage of blood and administration of products. To report new developments, controversial practices, less conventional blood product administration techniques and where applicable, describe the relevance to anaesthetists and anaesthesia.

Databases Used: PubMed and Google Scholar using dog, cat, blood transfusion, packed red blood cells and whole blood as keywords.

Assessment of clinical and laboratory variables as a guide to packed red blood cell transfusion of euvolemic anemic dogs.

Background: There are no standardized guidelines for determining the likelihood that euvolemic anemic dogs will benefit from transfusion of packed red blood cells (pRBC).

Objectives: To report clinical and laboratory variables of dogs receiving pRBC transfusion, which could guide transfusion of other anemic dogs.

Animals: Twenty-four client-owned anemic dogs receiving pRBC transfusion.

Use of arterial blood gas analysis as a superior method for evaluating respiratory function in pet rabbits (Oryctolagus cuniculus).

A retrospective study compared invasive (arterial blood gas analysis) and non-invasive (capnography and pulse oximetry) methods of monitoring respiratory function in conscious rabbits. Arterial samples from 50 healthy dwarf lop rabbits, presenting for routine surgical neutering, were analysed on a point-of-care blood gas analysis machine. Reference intervals were obtained for pH (7.

An unusual morphology of patent ductus arteriosus in a dog.

A 12-week old, entire female Border terrier weighing 3·5 kg was presented for investigation of a continuous left heart base murmur. The clinical presentation and preoperative echocardiogram were consistent with a standard morphology of patent ductus arteriosus (PDA) but a discrete ductal vessel was not identified during surgical dissection. Surgery had to be abandoned due to deterioration of the patient's condition under general anaesthesia which led to cardiorespiratory arrest and death despite attempts at resuscitation.
