Outcome for client-owned domestic rabbits undergoing limb amputation: 34 cases (2000-2009).

OBJECTIVE: To describe morbidity, function, outcome, and owner satisfaction associated with limb amputation in domestic rabbits. DESIGN: Retrospective case series. ANIMALS: 34 client-owned domestic rabbits. PROCEDURES: Medical records of domestic rabbits undergoing limb amputation for any cause between 2000 and 2009 were reviewed. The Kaplan-Meier method was used to estimate survival rate and median survival time, and variables were analyzed for relationship to risk of morbidity resulting in euthanasia and to outcome (survival vs nonsurvival [death or euthanasia]). Owners were interviewed to determine satisfaction with outcome of the procedure. RESULTS: 28 rabbits underwent pelvic limb amputation, and 6 underwent thoracic limb amputation. At the last follow-up, 18 rabbits were dead, 9 were alive, and 7 were lost to follow-up. Median overall survival time was 720 days (range, 4 to 3,250 days). Acute and delayed or chronic complications were observed in 22 of 34 and 19 of 32 rabbits, respectively, most commonly difficulty ambulating, hygiene issues, and pododermatitis (cutaneous ulcers at the hock). Six rabbits were euthanized because of complications at a median of 104 days (range, 4 to 399 days) after surgery. Risk of morbidity resulting in euthanasia increased with heavier body weight and concurrent disease affecting ambulation at the time of amputation. Weight, age, and pododermatitis at the time of amputation were significantly negatively associated with survival time. Thirty-one (91%) owners were satisfied with the outcome. CONCLUSIONS AND CLINICAL RELEVANCE: Although limb amputation was tolerated by most rabbits and most owners were satisfied, complications resulted in death in 6 of 34 (18%) rabbits, and 19 of 32 (59%) developed chronic complications. Amputation in heavy rabbits or those with concurrent pododermatitis, musculoskeletal disease, or neurologic disease should be considered carefully. Because of the small sample size and retrospective nature of this study, results should be interpreted as exploratory and hypothesis generating.

Cardiac arrests in schools: assessing use of automated external defibrillators (AED) on school campuses.

BACKGROUND: Sudden cardiac arrest in schools are infrequent, but emotionally charged events. The purpose of our study was to: (1) describe characteristics and outcomes of school cardiac arrests; and (2) assess the feasibility of conducting school bystander interviews to describe the events surrounding cardiac arrests, assess AED availability and use, and identify barriers to AED use. METHODS: We performed a telephone survey of bystanders to cardiac arrests occurring in K-12 schools in communities participating in the Cardiac Arrest Registry to Enhance Survival (CARES) database and a local cardiac arrest database. The study period was from 8/2005 to 8/2011 and continued in one community through 2011. Utstein style descriptive data and outcomes were collected. A structured telephone interview of a bystander or administrative personnel was conducted for each cardiac arrest event. We collected a descriptive event summary, including provision of bystander CPR, presence of an AED and information regarding AED deployment, training, and use and perceived barriers to AED use. Descriptive data are reported. RESULTS: During the study period there were 30,603 cardiac arrests identified at study communities, of which 47 (0.15%) events were at K-12 schools. Of these, 21 (45.7%) were at high schools, a minority (16, 34.0%) were children (

Post-traumatic stress disorder symptomology associated with witnessing unsuccessful out-of-hospital cardiopulmonary resuscitation.

OBJECTIVES: The objective was to assess symptoms of post-traumatic stress disorder (PTSD) associated with witnessing unsuccessful out-of-hospital cardiopulmonary resuscitation (CPR) on a family member. METHODS: Adult family members of deceased, adult, nontraumatic out-of-hospital cardiac arrest victims who were transported to a large, Midwestern hospital were contacted by telephone beginning 1 month after the event. Subjects were dichotomized as to whether or not they were physically present during the patient's resuscitation. A structured interview obtained the patient's prearrest functioning, whether the family member witnessed or performed CPR, patient and family demographic data, key cardiac arrest events, and a measure of subject PTSD symptoms (PTSD Symptom Scale-Interview [PSS-I]). RESULTS: There were 34 witnesses and 20 nonwitnesses. Each group was similar in race, religion, age, gender, and relationship to the patient. Patients in each group were similar in prearrest functioning. Witnesses' total PTSD symptom scores were nearly two times higher than nonwitnesses (14.47 vs. 7.60, respectively; mean difference = 6.87, 95% confidence interval [CI] = 0.57 to 13.17). Two PSS-I subscales were higher for witnesses than nonwitnesses: Avoidance (5.41 vs. 2.25; mean difference = 3.16, 95% CI = 0.74 to 5.58) and Increased Arousal (4.26 vs. 2.20; mean difference = 2.06, 95% CI = 0.08 to 4.05), while Reexperiencing was not (4.79 vs. 3.15; mean difference = 1.64, 95% CI = -0.62 to 3.91). Linear regression analysis indicated that witnessing CPR of a loved one was associated with a mean increase of nearly 12 points on the PSS-I after controlling for the possibility of other potentially influential events and characteristics. Results were similar when CPR providers (n = 6) were removed from the witness group. CONCLUSIONS: Witnessing a failed CPR attempt of a loved one in an out-of-hospital location may be associated with displaying symptoms of PTSD in the early term of the bereavement period. While preliminary, these data suggest that the relationship exists even after controlling for other potential factors that may also affect the propensity for displaying such symptoms, such as the suddenness and location of the patient's cardiac arrest.
