SummarySixteen cases of feline, non‐traumatic hemoperitoneum were evaluated retrospectively. The median age was 5.75 years (range 1.5 ‐ 16 years). There were eight male and eight female cats. Common presenting complaints (n=13) were anorexia (37%), lethargy (31%), and recumbency (31%). Physical examination findings (n=11) included depressed mentation (100%), hypothermia (89%), pale mucous membranes (82%), and poor quality pulses (80%). The median initial peripheral packed cell volume (n=11) was 24% (range 17‐55%). In four out of six cases where abdominocentesis was performed, the packed cell volume of the abdominal fluid ranged from 18% to 24%, and matched the peripheral packed cell volume (range 15 ‐ 26%). Some common abnormalities in the serum chemistry screens 9n=6) were elevated alanine aminotransferase in 83% (5/6) of the cats (range 55‐5828 U/l) and elevated alkaline phosphatase in 50% (3/6) of the cats (range 18‐402 U/l). Ten cats (63%) were euthanized, three (19%) were presented dead on arrival, two (12%) are still alive, and one (6%) were euthanized, three (19%) were presented dead on arrival, two 912%) are still alive, and one (6%) died. The causes of hemoperitoneum were hepatic neoplasia (31%), hepatic necrosis (19%), hepatic amyloidosis (13%), non hepatic neoplasia (13%), hepatopathy (6%), hepatic rupture (6%), necrotic/hemorrhagic cystitis (6%), and ruptured b

摘要:

SummaryAs the management of critically ill and emergency patients intensifies and veterinary surgical procedures become more complex, more sophisticated methods of support are becoming necessary. Emergency and critical care patients are excellent candidates for the use of neuromuscular blocking drugs. The main advantage of the current generation of neuromuscular blocking drugs compared to earlier agents is that they provide muscle relaxation with little or no cardiovascular effects. The pharmacology and physiology of neuromuscular blocking drugs are discussed, and their use is described with specific references to critical care patients. Monitoring techniques are described and reversal of neuromuscular blockade as well as potential side effects and adverse reactions arediscussed.

摘要:

SummaryReadings from 2 veterinary pulse oximeters (SDI Vet‐Ox #4402 and Nellcor N‐20V) were compared in 6 isoflurane‐anesthetized dogs. Simultaneous readings Of Sp02were recorded from 2 sites (toe and ear) over a range of inspired oxygen concentrations (15‐100%), and compared to directly measured SaO2readings. Greater variability of readings was obtained from the Vet‐Ox, which failed to give readings 25% of the time. The bias (mean SaO2‐Sp02) and precision (SD of bias) were calculated from the data for each oximeter. For the Vet‐Ox, bias (precision) from the toe was +4.O (5.2) and from the ear +1.7 (2.2). The bias (precision) for N‐20V readings from the toe was +1.6 (1.5) and from the ear +0.7 (1.5). Generally, both oximeters tended to underestimate SaO2; however, both overestimated at the lowest Pa02values. Pearscn cowelation coeefficients were 0.81 for the Vet‐Ox and 0.94 for the N‐20V for the combined data, including value from probes placed on the toe and ear at all inspired oxygen concentrations. In the two locatiom from which readings were obtained, the 2 units performe

摘要:

SummaryThe caudla vena cava (CVA) was evaluated as an laternative site for the measurement of central venous pressure (CPV) in six healthy, sedated (ketamine 10 mg/km, midazolam 0.1 mg/kg, and atropine 0.04 mg/kg IM) cats. The CVC was cathererized via medial saphenous puncture, and estimates of CPV from this site compared to those obtained via a jugular catheter. Simulataneous CPV values were recorded electronically (mmgh), via calibrated pressure transducer positioned at the level of the manubrium in cats in lateral recumbency. Five readings, performed at 1 minute intervals, were collected from the jugular and CVC catheters at rest (baseline) and following a rapid fluid bolus. Twenty‐four hours later, cats were resedated, baseline measurements repeated, and CVPs recorded following a rapid, 25% whole‐blood volume bleed. CVP measurements from the jugular and CVC were statistically compared using repeated measures ANOVA (p<0.05). There were no significant differences between the two sites in the baseline and bleed trials. Significant defferences between jugular and CVC CVPs were noted at 1 and 2 minutes following the fluid bolus. It was concluded that CVC is an alternative site for measurement of CPV in sedated c
