Monitoring cerebral oxygen saturation in elderly patients undergoing general abdominal surgery: a prospective cohort study.

BACKGROUND AND OBJECTIVES: The aim of this prospective, observational study was to evaluate changes in regional cerebral oxygen saturation (rSO2) and incidence of intraoperative cerebral desaturation in a cohort of elderly patients undergoing major abdominal surgery. METHODS: rSO2 was continuously monitored on the left and right sides of the forehead in 60 patients older than 65 yr (35 males and 25 females; ASA II-III; age: 72 +/- 5 yr; without pre-existing cerebral pathology, and baseline Mini Mental State Examination (MMSE) score >23) undergoing sevoflurane anaesthesia for major abdominal, non-vascular surgery >2 h. RESULTS: Baseline rSO2 was 63 +/- 8%; cerebral desaturation (rSO2 decrease <75% of baseline or <80% in case of baseline rSO2 <50%) occurred in 16 patients (26%). The MMSE decreased from 28 +/- 1 before surgery to 27 +/- 2 on 7th postoperative day (P = 0.05). A decline in cognitive function (decrease in MMSE score > or = 2 points one week after surgery as compared to baseline value) was observed in six patients without intraoperative cerebral desaturation (13.6%) and six patients who had intraoperative cerebral desaturation (40%) (P = 0.057) (odds ratio: 4.22; CI95%: 1.1-16). Median (range) hospital stay was 14 (5-41) days in patients with an area under the curve of rSO2 <50% (AUCrSO2<50%) >10 min%, and 10 (4-30) days in those with an AUCrSO2<50% <10 min% (P = 0.0005). CONCLUSIONS: In a population of healthy elderly patients, undergoing non-vascular abdominal surgery cerebral desaturation can occur in up to one in every four patients, and the occurrence of cerebral desaturation is associated with a higher incidence of early postoperative cognitive decline and longer hospital stay.

Conscious analgosedation for radiofrequency ablation of lung neoplasm.

AIM: Radiofrequency ablation (RFA) is a minimally invasive therapy for pulmonary malignant cancers in patients with medical co-morbidities or refusal of surgery. The aim of this study was to evaluate a conscious analgosedation protocol for RFA of lung neoplasm. METHODS: Ten RFAs were performed. Following analgesic premedication patients underwent local anesthesia (lidocaine 2%) and propofol infusion. RESULTS: The procedures were always uneventful. Postoperative severe pain was not reported; a deep sedation was required to allow the quick and safe management of RFA. CONCLUSIONS: Spontaneous breathing sedation is safe in monitored and well-oxygenated patients and may limit the incidence of tension pneumothorax. Postoperative period needs a proper pain control for the first 24 h. Data on the long-term efficacy of lung tumor RFA are not yet available.

Sepsis and organ dysfunction: an ongoing challenge.

In recent years the problem of infection has become increasingly significant, especially in intensive care hospital wards such as Intensive Care Units (ICU), emergency medicine, surgery and critically ill patient care departments. Sepsis is a complex, multifactorial syndrome that can develop into conditions of different severity, described as severe sepsis or septic shock. In these conditions the triggering event may coincide with the functional impairment of one or more vital organs or systems, thus leading to poorer prognosis in patients with overt signs of sepsis or systemic inflammation syndromes. The available data are quite alarming, as most prevention and treatment is performed empirically and requires considerable human and technological resources. Clinical signs are often misleading and, in some circumstances, it may be difficult or even impossible to identify the source of the infection which might otherwise be removed relatively simply, using proper antimicrobial treatment or a less invasive surgical removal of the area from which the infection originates based on needle-guided radiology. In addition, the complex pathophysiological mechanisms involved can be an obstacle to gaining a full understanding of the various biohumoral interactions or mediators action mechanisms. It may not be easy to enroll patients belonging to homogeneous groups in terms of age, underlining disease, immune profile or genetic predisposition, although the use of specific severity indexes has proved helpful also to establish the prognosis. Although the interpretation of generalised inflammation as a warning sign also in the absence of clear signs of infection or a state of overt inflammation has to rely largely on simple intuition, it has helped to drive experimental and clinical research work towards the investigation of interaction between different factors such as infection and sepsis, or inflammation and coagulation. An additional useful tool is the possibility of modulating the endothelial response which may support the process of disseminated thrombosis typical of sepsis evolution. In this context the improvement of standards of care can shed light on the efficacy of different treatments.

S100B is a sensitive but not specific prognostic index in comatose patients after cardiac arrest.

AIM: The aim of this study was to compare serum S100B levels and EEG findings as prognostic indexes in comatose (GCS<8) patients after cardiac arrest. METHODS: S100B serum levels were assessed 12 h after the event and EEG findings were recorded within 24 h in comatose cardiac arrest survivors. At hospital discharge, patients were divided into groups according the Glasgow-outcome scale (GOS): group 1 with bad neurological outcome and group 2 with good neurological outcome (GOS 4-5). S100B levels and EEG findings were retrospectively tested about their predictive value. RESULTS: S100B has a very low specificity (37.5%) while S100B sensitivity is 100%. EEG findings specificity is 75% and sensitivity 50%. S100B was not significantly lower in patients who recovered consciousness (10 patients) and there was no significant difference in EEGs findings between group 1 and 2. CONCLUSIONS: The association of serum S100B levels with EEG might be helpful when used together to formulate outcome in comatose patients within 24 h after cardiac arrest. However, increased levels of S100B 12 h after a cardiac arrest might be expression of a still amendable brain damage.

Incidence of antimicrobial-resistant ventilator associated pneumonia: an eighteen-month survey.

AIM: Microbes commonly involved in ventilator associated pneumonia (VAP) are difficult to eradicate: Pseudomonas aeruginosa and Acinetobacter baumannii are often resistant to piperacillin, aztreonam and ceftazidim while Klebsiella pneumoniae and other Enterobacteriaceae are resistant to third generation cephalosporins. Physicians need to tailor their therapeutic approach depending on individual patients and clinical setting, firmly based on local epidemiology. The aim of this study was to assess the incidence of VAP caused by multidrug-resistant bacteria in our ICU. METHODS: We conducted a retrospective review of all patients mechanically ventilated for longer than 72 h, who developed pneumonia over an eighteen-month period for whom final culture data were available. One-hundred and forty-three patients admitted to a University Hospital medical surgical ICU were included in this survey. VAP was diagnosed by Centers for Disease Control and Prevention criteria and confirmed by mini- bronchoalveolar lavage. RESULTS: In this study, the incidence of VAP in the period January 1, 2002-June 31, 2003 was very high, accounting for about 20% of all at-risk cases. Multiresistant agents were involved in about 57% of VAP occurring within 7 days of mechanical ventilation, and in 80% of late VAP. CONCLUSIONS: This study revealed differences in VAP incidence and features among our ICU and literature data, indicating a need for caution when using hospital infection surveillance data for comparisons and choice of therapy. In our setting, with high levels of antibiotic resistance, combined approaches of non-antibiotic using strategies and education programs might be beneficial.

[Organ donor and health policy: the anaesthesia and reanimation].

The possibility of tissues and organs transplantation is nowadays an ordinary surgical procedure for patients that do not have other way of treatment. Today the principal objective of the National Health Care System is the improvement in the transplantation activities. To achieve this objective it is necessary to sustain and promote donation, which is still the principal resource that can be used to satisfy the needs of the patients in waiting list for transplantation. In Italy much has been done by Institutions and physicians with excellent results, both in terms of number of donations and quality of transplantations. But it is still not sufficient. A non homogeneity is still observed between different Provinces, not only in terms of donation, but also in terms of number of transplantation. This situation does not contribute to guarantee the same level of accessibility to health care assistance, which patients deserve. To solve these problems the National Health Care Plan 2003-2005 has indicated, among the strategic objectives, a better utilization of organs and a more deep campaign of information for all citizens. It is important that all the Institutions and all the operators involved would give more attention to the donation process problems and would always be active and efficient. Only keeping a high level of involvement of the local coordinators and of the anaesthetists and intensive, pivotal figures in the process of donation, and reminding to all citizens the possibility of a "love sign", fruit of a decision born by a personal analysis, it will be possible to offer a possibility of life to the patients for whom up today no other treatments exists.
