On the basis of these observations, we conclude that tracheotomized mechanically ventilated ICU patients required less intravenous sedative administration, spent less time heavily sedated, and achieved more autonomy earlier.
Our objective was to characterize both epidemiologically and clinically manifestations after severe scorpion envenomation and to define simple factors indicative of poor prognosis in children. We performed a retrospective study over 13 years (1990–2002) in the medical intensive care unit (ICU) of a university hospital (Sfax-Tunisia). The diagnosis of scorpion envenomation was based on a history of scorpion sting. The medical records of 685 children aged less than 16 years who were admitted for a scorpion sting were analyzed. There were 558 patients (81.5%) in the grade III group (with cardiogenic shock and/or pulmonary edema or severe neurological manifestation [coma and/or convulsion]) and 127 patients (18.5%) in the grade II group (with systemic manifestations). In this study, 434 patients (63.4%) had a pulmonary edema, and 80 patients had a cardiogenic shock; neurological manifestations were observed in 580 patients (84.7%), 555 patients (81%) developed systemic inflammatory response syndrome (SIRS), and 552 patients (80.6%) developed multi-organ failure. By the end of the stay in the ICU, evolution was marked by the death in 61 patients (8.9%). A multivariate analysis found the following factors to be correlated with a poor outcome: coma with Glasgow coma score ≤ 8/15 (odds ratio [OR] = 1.3), pulmonary edema (OR = 2.3), and cardiogenic shock (OR = 1.7). In addition, a significant association was found between the development of SIRS and heart failure. Moreover, a temperature > 39°C was associated with the presence of pulmonary edema, with a sensitivity at 20.6%, a specificity at 94.4%, and a positive predictive value at 91.7%. Finally, blood sugar levels above 15 mmol/L were significantly associated with a heart failure. In children admitted for severe scorpion envenomation, coma with Glasgow coma score ≤ 8/15, pulmonary edema, and cardiogenic shock were associated with a poor outcome. The presence of SIRS, a temperature > 39°C, and blood sugar levels above 15 mmol/L were associated with heart failure.
Critical care clinicians no longer consider family members as visitors in the intensive care unit. Family-centered care has emerged from the results of qualitative and quantitative studies evaluating the specific needs of families of patients dying in the intensive care unit. In addition, interventional studies have established that intensive and proactive communication empowers family members of dying patients, helping them to share in discussions and decisions, if they so wish. In addition to intensive communication, interventional studies have highlighted the role of nurses, social workers, and palliative care teams in reducing family burden, avoiding futile life-sustaining therapies, and providing effective comfort care. End-of-life family conferences are formal, structured meetings between intensivists and family members. Guidelines for organizing these conferences take into account the specific needs of families, including reassurance that the patient's symptoms will be adequately managed; honest clear information about the patient's condition and treatment; a willingness on the part of physicians to listen and respond to family members and to address their emotions; attention to patient preferences; clear explanations about surrogate decision making; and continuous, compassionate, and technically proficient attention to the patient's needs until death occurs. Means of improving end-of-life care have been identified in epidemiologic and interventional studies. End-of-life family conferences constitute the keystone around which excellent end-of-life care can be built.
In Tunisia, head injury is a frequent cause of hospitalization, comprising 14.4% of all adult admissions. It is observed most often among young patients involved in traffic accidents. The short-term prognosis is poor, with a high (29%) mortality rate, and determined by demographic, clinical, radiologic, and biologic factors. Prevention is highly advised.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
