The Self-Inflicted Burns - Typology and its Prognostic Relevance in a 14-Year Review of Self-Inflicted Burns in a Tertiary Referral Centre

Self-inflicted burns (SIB) are responsible for 2-6% of admissions to Burn Units in Europe and North America, and for as many as 25% of admissions in developing nations. Recently, a promising new tool was proposed to stratify SIB patients in the following subgroups: "typical", "delirious", and "reactive". However, as far as the authors know, the clinical usefulness of this instrument has not yet been validated by others. We retrospectively reviewed the clinical records of 56 patients admitted to our Burn Unit with the diagnosis of SIB injury in the past 14 years. The following parameters were evaluated: demographic features; psychiatric illness; substance abuse; mechanism of injury; burn depth, total body surface area (TBSA) involved, Abbreviated Burn Severity Index (ABSI); length of hospital stay, and mortality. All patients were followed up by a psychologist and a psychiatrist, and were classified according to the SIB-Typology Tool, into three classes: "typical", "delirious" and "reactive". There was a slight predominance of the "typical" type (44.6%), followed by the "delirious" type (30.4%), and, finally the "reactive" type (25.0%). Mortality was significantly higher in the "typical" subgroup. In conclusion, the SIB-Typology Tool appears to be a valuable instrument in the clinical management of SIB patients.

Expansão Tissular Seriada e Múltipla nas Sequelas de Queimaduras

The authors present the case of a 16 year old female with 3rd degree burn sequelae. They describe the surgical steps during the three years of treatment with serial and multiple tissue expansion. From the 9 tissue expanders used with reference capacities of 3350cc, 10350 were achieved. The conclusions point out the utility of this technique, using re-expansion and supraexpansion as one, should be associated with careful surgical planning and constant rapport with the patient.

Lesões Inalatórias no Doente Queimado

Inhalation injuries are currently the factor most responsible for mortality in thermally injured patients. Inhalation injuries may occur independently, but generally occur together with skin burn. Smoke inhalation affects all levels of the respiratory system and the extent of the inhalation injury depends on the duration, exposure, amount and toxicity of the fume temperature, concentration and solubility of toxic gases, the occurrence of the accident in a closed space and pre-existing diseases. Smoke inhalation also induces changes in the systemic organs with the need for more fluid for resuscitation. Systemic vasoconstriction, with an elevation in systemic vascular resistance, a fall in myocardial contractility and a great increase in lymphatic flow in soft tissue are the most important changes in systemic organs. On admission of a burn patient there is a high suspicion of inhalation injury when there are signs and symptoms such as hoarseness, strides, dyspnea, carbonaceous sputum, anxiety or disorientation, with or without face burns. The patient with these findings has partial airway obstruction and there is substantial risk complete airway obstruction occurring of secondary to the edema. Patients with suspected inhalation injury should be intubated so as to maintain airway patency and avoid a total obstruction. This group of patients frequently develop respiratory failure with the need for mechanical ventilatory support. Nosocomial infections, sepsis and multiple organ system failure may occur. Late complications of inhalation injury are tracheitis, tracheal stenosis or tracheomalacia and chronic airway disease, which is relatively rare. Early diagnosis of inhalation injury and treatment in a Burn Unit by a group of highly motivated clinicians and a good team of nurses is essential in order to decrease the morbidity and mortality related to inhalation injury.

Grande Queimado em Cuidados Intensivos Pediátricos

O grande queimado é um doente de grande labilidade hidroelectrolítica, que justifica internamento numa unidade de cuidados intensivos até à sua estabilização. Efectuou-se um estudo retrospectivo dos doentes queimados internados na UCIP do HDE, num período de oito anos e meio compreendido entre Abril de 1991 e Setembro de 1999. Foram internadas 33 crianças, 8 das quais tiveram mais do que um internamento. Os agentes causais foram o fogo em 12 crianças, a corrente eléctrica também em 12 crianças e os líquidos quentes em 9. Os doentes queimados por fogo apresentaram área mais extensa de queimadura (46.9 ± 22.6%), e consequentemente maior duração de internamento (462.1 ± 884.1 horas), maior grau de instabilidade fisiológica (pRISM 11.3 ± 4.9) e maior intervenção terapêutica (TISS 31.2 ± 9.0). Nao se observaram reinternamentos no grupo das queimaduras electricas, que globalmente apresentaram menor gravidade nas variáveis estudadas. Dos 8 reinternamentos, 6 ocorreram no grupo dos queimados pelo fogo. Observaram-se 6 óbitos, cinco dos quais no grupo dos reinternamentos. Todos os óbitos foram causados por sépsis e choque séptico.

The Support Role in Clinical Supervision of Nursing Students: Determinant in the Development of Emotional Skills

The problematic situation faced by clients, associated to the processes of health and disease, is expressed through emotions that nursing students have to deal with in the course of care and their formative experiences in clinical teaching. Students have learning needs not only to manage emotions in the context of customer care, but also in terms of their own internal world, emotional conflicts, emotional stress and burn-out. With the present literature review, we intend to explore existing evidence regarding the ways in which the nurse supervisor's support towards nursing students potentiates the development of their competences for the performance of emotional labour. These skills prove to be the key in the ability to manage the emotionally intense situations of care practice and the support function of the nursing supervisor contributes to the development of such competences.
