Radiographic evaluation of uterine enlargement is discussed and illustrated. Normal (pregnancy) and abnormal (pyometra, complications of pregnancy, neoplasma) causes of uterine enlargement are addressed. Special radiographic procedures for uterine evaluation are described. 相似文献

Objective To compare the cardiopulmonary effects and sensory blockade of epidural bupivacaine and ropivacaine. Study Design Prospective randomized study. Animals Six young adult medium‐sized crossbred dogs weighing 25.7 ± 7.1 kg. Method Dogs were chronically implanted with a lumbosacral epidural catheter. Acepromazine sedated dogs received all treatments: 0.5% bupivacaine at 0.14 mL kg?1 (LB5) or 0.22 mL kg?1 (HB5); 0.5% ropivacaine at 0.14 mL kg?1 (LR5) or 0.22 mL kg?1 (HR5); 0.75% bupivacaine at 0.22 mL kg?1 (HB7.5) or 0.75% ropivacaine at 0.22 mL kg?1 (HR7.5). Loss of sensation was tested at the level of the perineum, hind toe webs, flank, and caudodorsal rib areas before injection, and post‐injection (PI) up to 150 minutes PI. Systemic arterial blood pressure and heart rate were recorded before injection, and every 10 minutes PI until 150 minutes PI. Arterial blood gas analyses were performed prior to injection, and at 30, 60 and 150 minutes PI. Results No statistical differences existed between groups for the cardiopulmonary data or time to onset of block. Group HR7.5 had lower systolic (10–70 minutes PI) and diastolic (10–70 minutes PI) blood pressures and group HR5 had lower mean (10–90 minutes PI) and diastolic (10–90 minutes PI) blood pressures compared to baseline. Heart rate was lower compared to baseline in groups LR5 and HB7.5. A significant, but mild metabolic acidosis developed in groups LR5 and HB7.5 (150 minutes PI). No differences were present for the duration of block between groups, but duration of block in the dorsocaudal rib area was shorter in group HR5 compared to HR7.5. Conclusion Epidural ropivacaine and bupivacaine at the doses used have mild effects on the cardiopulmonary system, and extent of block are similar. Clinical Relevance The 0.75% concentration of bupivacaine and ropivacaine at 0.22 mL kg?1 appeared to contribute to greater success of block (>80%) at dermatomes L5–L7. 相似文献

The purpose of this retrospective study was to determine the feasibility of using the end-to-end anastomosis (EEA) stapling device transrectally for managing distal colonic disease in clinical veterinary cases. Ten animals met the criteria of having distal colonic or rectal resection and anastomosis with the EEA stapling device. The only complications seen after discharge from the hospital were colonic stricture at the anastomosis site in two animals and transient colitis in two animals. The stapled anastomosis has good success when properly applied, and the incidences of stricture formation, leakage, and other potential complications can be kept to a minimum. 相似文献
