OBJECTIVE: To evaluate the effectiveness of a forced-air warming blanket (FAWB) in minimizing anesthetic-induced hypothermia in cats, and to examine the relationship between esophageal and other estimates of body temperature during skin surface warming. STUDY DESIGN: Prospective, randomized cross-over trial. ANIMALS: Eight adult domestic shorthair cats (four males and four females) weighing 2.3 to 4.5 kg. METHODS: Each cat was anesthetized with halothane in oxygen on four occasions and covered with a modified FAWB. Air delivered to the cats by the FAWB was warmed to approximately 43 degrees C. Each trial lasted 90 minutes and was divided into two consecutive 45-minute periods, during which the FAWB was activated or inactivated thus creating four treatment trials: off/off, on/off, on/on, off/on. Measurements of body temperature from the caudal esophagus, deep rectum, toe-web, and tympanic membrane were recorded at regular intervals throughout each trial and compared. RESULTS: A steady decline in body temperature was observed throughout each trial. Mean body temperature in the cats receiving continual skin surface warming (on/on) was significantly higher than in those receiving no active warming (off/off) and those receiving delayed warming (off/on), from 45 minutes onwards. By 90 minutes, the mean body temperature of cats warmed continuously was 0.9 degrees C higher than in those with no active warming. Notable differences in body temperature were detected between all measurement sites, with the exception of esophagus versus rectum. Rectal and esophageal temperatures did not differ at any time point. Tympanic membrane temperatures measured with either device were lower than esophageal temperatures. CONCLUSIONS: The modified FAWB was effective in minimizing the degree of hypothermia experienced in cats anesthetized with halothane for 90 minutes. Deep rectal temperature was an accurate reflection of esophageal temperature in these cats. CLINICAL RELEVANCE: Forced air warming blankets may prove successful in minimizing anesthetic-induced hypothermia in cats. 相似文献

Objective To compare the fresh gas flow requirements of the ‘Maxima’ and Jackson‐Rees modified Ayre's T‐piece (JRMATP) in spontaneously breathing anaesthetized in cats. Study design Prospective randomized clinical study. Animals or sample population Fifteen adult cats (6 male, 9 female, 3.1 ± 0.4 kg [x? ± SD]). Materials & methods After pre‐anaesthetic medication with acepromazine and pethidine, anaesthesia was induced using thiopentone and the trachea was intubated with a cuffed endotracheal tube. This was attached to either a ‘Maxima’ or a JRMATP breathing system; allocation was randomized. Anaesthesia was maintained with halothane delivered in a 1 : 1 oxygen : nitrous oxide mixture. Initial total fresh gas flow (FGF) was set at 600 mL kg?1 min?1. After 20 minutes, FGF was reduced in increments of 200 mL min?1 until rebreathing (inspired CO2 concentration >0.2%) occurred. At this point, FGF was increased to 600 mL kg?1 and the process was repeated with the other breathing system. The respiratory rate and airway pressure at the endotracheal tube connector were monitored throughout anaesthesia. Results The mean fresh gas flow that prevented rebreathing with the Maxima system (164 ± 39 mL kg?1) was significantly less (p < 0.0001) than that required in the modified T‐piece (455 ± 0.77 mL kg?1). Respiratory rates and airway pressures at the endotracheal tube connector were not significantly affected by breathing system employed. Conclusions In terms of the gas flow requirements that prevent rebreathing, the ‘Maxima’ breathing system is more efficient than the modified Ayre's T‐piece in spontaneously breathing cats anaesthetised with halothane. 相似文献

Two dogs had right divisional intrahepatic portacaval shunts within the right lateral lobe of the liver. In both dogs, an extrahepatic portacaval vascular anastomosis was created, using an autologous right external jugular vein graft. The intrahepatic shunts were completely attenuated using a prehepatic intravascular caval approach. The creation of the vascular graft allowed postattenuation rises in portal pressure to be controlled, preventing the development of life threatening portal hypertension. Both dogs recovered from the procedure. One dog is clinically normal and does not require medication (8 months postoperatively); the other dog was euthanatized 5 months after surgery because of renal failure. Scintigraphy studies, performed before surgery, showed significant shunting of portal blood away from the liver (shunt indices 65% and 59%), whereas, similar studies done 4 weeks afterwards showed almost normal portal blood flow (shunt indices 16% and 18%, respectively). 相似文献
