RESUMO

Hypertonic saline solution (HSS) has been investigated in the treatment of intracranial hypertension (ICH) in a limited number of studies, usually after failure of conventional treatment. HSS, used in concentrations that vary from 3% to 23.4%, seems to be effective in reducing refractory ICH and to be devoid of adverse effects. We treated a patient with refractory ICH with a small-volume infusion of 18% HSS, and performed magnetic resonance imaging (MRI) before and after HSS infusion. MRI showed a marked reduction in cerebral water content 1 h after the infusion. To our knowledge, this is the first MRI study in a patient with brain injury to evaluate the effect of HSS on brain water content. Further studies are necessary to test HSS efficacy and to identify, through MRI or computed tomography (CT) scan imaging, a subgroup of patients with brain injury who would be best treated with HSS.

RESUMO

The objective of this prospective, randomized, double-blind study was to evaluate the effect of the addition of mupirocin to the 'classical' topical SDD regimen (tobramycin 80 mg, polymyxin E 100 mg, amphotericin B 500 mg) on the development of ICU-acquired infections due to gram-positive bacteria. The study was carried out in an intensive care unit (ICU) of a 1400-bed community hospital. All patients admitted to the ICU during a 16-month period, who were expected to require mechanical ventilation for more than 24 hours, were randomized to receive either the 'classical' SDD regimen (Group A) or a modified regimen with mupirocin (Group B). Data from 223 patients requiring mechanical ventilation for at least 48 hours, who were neither infected nor receiving antibiotics on ICU admission, was analysed. A 2% paste containing tobramycin, polymyxin E and amphotericin B was applied every 6 hours in the oropharynx to the patients in Group A, while in Group B this formula was modified with the addition of 2% mupirocin. In Group B 0.2 ml of a 2% mupirocin ointment was also applied four times daily in both nostrils. Patients in Group A received a soft paraffin ointment as a placebo indistinguishable from mupirocin. Patients in both groups received the classic SDD regimen through the nasogastric tube. Systemic antibiotic prophylaxis was not used. Data on lower airway infection, and blood infection, infections of intravascular catheters, antibiotic consumption and expenditures for antibiotics were analysed. The diagnosis of ventilator-associated pneumonia (VAP) was based on quantitative cultures of protected specimen brush samples (PSB) or on the results of distal broncho-alveolar lavage (BAL). One hundred and four patients received the 'classical' SDD and 119 the modified regimen. Overall 29 patients, 20 in Group A and nine in Group B (p < 0.02) had a total of 33 cases of pneumonia. There were 23 episodes of pneumonia in Group A and 10 in Group B (p < 0.02). Gram-positive bacteria were isolated from samples in 17 episodes in Group A and six in Group B (p < 0.02). Staphylococcus aureus was isolated in nine cases of pneumonia in Group A and once in the 'mupirocin' group (p < 0.05). MRSA were isolated in seven out of nine cases in Group A and in the only case in Group B. There were no differences in the isolation of gram-negative bacilli. Antibiotic consumption and cost were lower in Group B. In conclusion, our data show that the topical use of a modified formula of SDD, with the addition of mupirocin to the oral paste and in the anterior nares, is associated with a reduction in lung infections caused by gram-positives and in a reduction in antibiotic consumption and in the overall expenditure for antibiotics.

RESUMO

The hypothesis that high level on-the-field ATLS could influence mortality in severe trauma patients was tested by means of a prospective study. During a 7 month period, data of all the victims of severe involuntary trauma (road traffic accidents, work and sport accidents) in 3 Provinces of north-east Italy were entered in a database and analysed. The whole area is covered by a single emergency service which has direct control over all the ambulances and the Emergency Helicopter Service (EMHS). The area concerned by the study has a surface of 7,300 kmq with a population of 1 million inhabitants and is served by 12 first level hospitals and 4 second level institutions (trauma centres). All the patients who were still alive at the time of arrival of the first rescuers were considered, but only severe trauma patients with ISS > 15 were enclosed into the study. All the patients were followed up to their discharge from the ICUs (end point). There were three different rescue approaches: 82 Patients (GROUP A) were rescued by EMTs with BLS training, transported to the nearest level 1 hospital for stabilisation and subsequently transferred to a trauma center; 98 Patients (GROUP B) were rescued by EMTs and directly transported to a trauma centre which was the nearest institution; 42 Patients were rescued on the scene by the EMHS team including an anaesthesiologist with 10 years experience in trauma care and directly transported to a trauma centre after full on-the-field stabilisation (GROUP C) RESULTS: 222 severe trauma patients (ISS > 15) were considered. Mean ISS was 35.1 +/- 18.2 in group A, 33.4 +/- 19.6 in group B and 36.0 +/- 17.8 in group C. 67 patients died previous to ICU discharge (31%). 31 over the 82 pts in Group A (38%) died. 23 of them died even before reaching the trauma centre. The mean time elapsed between the first emergency call and the arrival at the trauma centre was 162 min (90'-300'). Mean ICU stay for patients who survived was 15 days. In Group B 31 over 98 patients (32%) died before ICU discharge. The mean time between the emergency call and hospital admission was 27'. Mean ICU stay for patients who were discharged, was 13 days. 5 over 42 patients rescued by the EMHS (Group C) died, none of them in the pre-hospital setting. Stabilisation included tracheal intubation in 34 cases (81%) and thoracic drainage in 6 (14%). All the patients arrived at the hospital with 2 i.v. line. The average amount of infused fluids were 600 mls of colloids and 810 mls of crystalloid. 13 patients with hypotension received and average of 1000 mls of colloids and 1200 mls of crystalloid. The average time elapsed between the emergency call and the final admission to the definitive care institution was 55'. Mean ICU stay was 11 days. Mortality rate in this group was 12%, significantly lower than in group A (p < 0.005) and group B (p < 0.05).
