Silver negative pressure dressing with vacuum-assisted closure of massive pelvic and extremity wounds.

BACKGROUND: Massive soft tissue loss involving the pelvis and extremities from trauma, infections, and tumors remains a challenging and debilitating problem. Although vacuum-assisted closure (VAC) technology is effective in the management of soft tissue loss, the adjunct of a silver dressing in the setting of massive wounds has not been as well tested. QUESTIONS/PURPOSES: Does a silver negative pressure dressing used in conjunction with a wound VAC decrease (1) the length of acute hospital stay and overall length of treatment; (2) the number of surgical débridements the patients underwent as part of their care; and (3) the likelihood of wound closure without soft tissue transposition? METHODS: We evaluated 42 patients with massive (> 200 cm(2)) pelvic and extremity wounds from trauma, infection, or tumor who were treated with the wound VAC with or without a silver negative pressure dressing between January 2003 and January 2010; the first 26 patients were treated with the wound VAC alone, and in the final 16 consecutively treated patients, the silver dressing was added to the regimen. We reviewed medical records to determine length of treatment as well as the number and type of surgical interventions these patients underwent. We compared the group treated with the wound VAC alone with those patients treated with the wound VAC and silver negative pressure dressing. RESULTS: Hospital stay averaged 19 days in the VAC only group and 7.5 days in the VAC with silver dressing group (p < 0.041), length of overall treatment averaged 33 days in the VAC only group and 14.3 days in the VAC with silver dressing group (p < 0.022), number of operative débridements averaged 7.9 in the VAC alone group and 4.1 in the VAC with silver dressing group (p < 0.001), and success of wound closure without soft tissue transposition was 16 of 26 patients in the VAC alone group and three of 16 patients in the VAC with silver dressing group (p < 0.033). CONCLUSIONS: Based on the reduced length of care and the number of surgical procedures these patients with massive wounds of the pelvis and extremities underwent, we now use the silver negative pressure dressing in combination with the wound VAC as part of routine care of such patients. These results may be used as hypothesis-generating data for future randomized studies. LEVEL OF EVIDENCE: Level III, therapeutic study.

Management of snakebite and systemic envenomation in rural Ecuador using the 20-minute whole blood clotting test.

OBJECTIVES: In low-income countries, snakebites are frequently managed in rural areas in health centers with severely constrained resources. Many healthcare providers in these settings have limited access to the numerous and relatively expensive laboratory studies used to diagnose envenomation. The relatively simple and inexpensive 20-minute whole blood clotting test (WBCT) has been recommended by several international organizations for the diagnosis of certain venomous snakebites. This study proposes to confirm the utility of the WBCT as the sole laboratory diagnostic tool to determine systemic envenomation in hematotoxic snakebite management in severely resource-constrained areas of the world. METHODS: The authors reviewed all 110 cases of snakebite during a 6-year period in a small hospital in rural Ecuador using the WBCT. RESULTS: All cases presented within 24 hours of snakebite. Twenty cases revealed normal coagulation with no clinical evidence of systemic envenomation. Ninety cases had no evidence of clot formation (positive WBCT) at 20 minutes, suggesting systemic envenomation. Of these 90 cases, according to a classification scale, 54 were mild, 26 were moderate, and 10 were severe envenomations requiring transfer to tertiary care. All mild and moderate systemic envenomations were successfully treated at the rural hospital. All severe envenomations were treated initially with antivenom before transfer to tertiary care. One patient with severe envenomation died in tertiary care. CONCLUSIONS: The WBCT was predictive of the presence or absence of systemic envenomation from snakebite in our region. The WBCT guided the successful management of mild and moderate systemic envenomation, and spared patients with no evidence of systemic envenomation from potential side effects of antivenom.

Quantifying the reduction in nonmedical costs after the introduction of a rural county hospital in Ecuador.

OBJECTIVE: This study attempts to quantify the impact of the introduction of local second-level health services on nonmedical costs (NMCs) for residents of the rural Ecuadorian county of La Maná. METHODS: NMCs for patients accessing second-level health care were assessed by using a quasi-experimental pre- and postintervention study design. In 2007, before local second-level health care services existed, and then in 2008, after the introduction of second-level health care services in the form of a county hospital, 508 patients from the county who sought second-level health care were interviewed. RESULTS: Mean NMCs per patient per illness episode were US$ 93.58 before the county hospital opened and US$ 12.62 after it opened. This difference was largely due to reductions in transport costs (US$ 50.01 vs. US$ 4.28) and food costs (US$ 25.38 vs. US$ 7.28) (P < 0.001 for each category). CONCLUSIONS: NMCs can be decreased sevenfold with the introduction of a county hospital in a rural province previously lacking second-level health care. Introduction of rural second-level health care reduces financial barriers and thus may increase access to these health services for poorer patients in rural communities.

OBJETIVO: Este estudio tiene por objeto cuantificar la repercusión de la introducción de servicios de salud locales de segundo nivel sobre los costos no médicos para los residentes del cantón rural ecuatoriano de La Maná. MÉTODOS: Se evaluaron los costos no médicos de los pacientes que tuvieron acceso a atención médica de segundo nivel mediante un estudio cuasiexperimental de análisis previo y posterior a la intervención. En el 2007 (antes de que existieran servicios locales de este tipo) y en el 2008 (después de la introducción de atención médica de segundo nivel representada por el hospital del cantón) se entrevistaron a 508 pacientes del cantón que requirieron atención médica de segundo nivel. RESULTADOS: Los costos no médicos medios por paciente y por episodio de enfermedad fueron de US$ 93,58 antes de la apertura del hospital local y de US$ 12,62 después de la inauguración del establecimiento. Esta diferencia se debió en gran parte a la reducción de los costos de transporte (US$ 50,01 frente a US$ 4,28) y de los costos de alimentación (US$ 25,38 frente a US$ 7,28) (P < 0,001 para cada categoría). CONCLUSIONES: Es posible reducir los costos no médicos a una séptima parte mediante la apertura de un hospital local en una zona rural que anteriormente carecía de atención médica de segundo nivel. La introducción de atención médica de segundo nivel en una zona rural reduce los obstáculos financieros y, por lo tanto, podría aumentar el acceso a estos servicios de salud para los pacientes más pobres en las comunidades rurales.
