Holy consent--a dilemma for medical staff when maternal consent is withheld for emergency caesarean section.

A parturient (grand multipara) developed arrested labour complicated by severe fetal heart rate decelerations. Senior physicians explained the need for a caesarean section, but she chose to deliver vaginally since rabbinical blessing could not be obtained. Forcing the mother to have a cesarean section without consent is considered "civil battery." The dilemma faced by medical staff and the implications of her refusal for the treating medical staff are described.

The impact of regional culture on intensive care end of life decision making: an Israeli perspective from the ETHICUS study.

BACKGROUND: Decisions of patients, families, and health care providers about medical care at the end of life depend on many factors, including the societal culture. A pan-European study was conducted to determine the frequency and types of end of life practices in European intensive care units (ICUs), including those in Israel. Several results of the Israeli subsample were different to those of the overall sample. OBJECTIVE: The objective of this article was to explore these differences and provide a possible explanation based on the impact of culture on end of life decision making. METHOD: All adult patients admitted consecutively to three Israeli ICUs (n = 2778) who died or underwent any limitation of life saving interventions between 1 January 1999 and 30 June 2000 were studied prospectively (n = 363). These patients were compared with a similar sample taken from the larger study (ethics in European intensive care units: ETHICUS) carried out in 37 European ICUs. Patients were followed until discharge, death, or 2 months from the decision to limit therapy. End of life decisions were prospectively organised into one of five mutually exclusive categories: cardiopulmonary resuscitation (CPR), brain death, withholding treatment, withdrawing treatment, and active shortening of the dying process (SDP). The data also included patient characteristics (gender, age, ICU admission diagnosis, chronic disorders, date of hospital admission, date and time of decision to limit therapy, date of hospital discharge, date and time of death in hospital), specific therapies limited, and the method of SDP. RESULTS: The majority of patients (n = 252, 69%) had treatment withheld, none underwent SDP, 62 received CPR (17%), 31 had brain death (9%), and 18 underwent withdrawal of treatment (5%). The primary reason given for limiting treatment was that the patient was unresponsive to therapy (n = 187). End of life discussions were held with 132 families (36%), the vast majority of which revolved around withholding treatment (91% of the discussions) and the remainder concerned withdrawing treatment (n = 11, 9%). There was a statistically significant association (chi2 = 830.93, df = 12, p < 0.0001) between the type of end of life decision and region-that is, the northern region of Europe, the central region, the southern region, and Israel. CONCLUSIONS: Regional culture plays an important part in end of life decision making. Differences relating to end of life decision making exist between regions and these differences can often be attributed to cultural factors. Such cultures not only affect patients and their families but also the health care workers who make and carry out such decisions.

Increased risk of bloodstream and urinary infections in intensive care unit (ICU) patients compared with patients fitting ICU admission criteria treated in regular wards.

Critically ill patients, eligible for admission into intensive care units (ICUs), are often hospitalized in other wards due to a lack of ICU beds. Differences in morbidity between patients managed in ICUs and elsewhere are unknown, specifically the morbidity related to hospital-acquired infection. Patients fitting ICU admission criteria were identified by screening five entire hospitals on four separate days. Hospital infections within a 30-day follow-up period were compared in ICU patients and in patients on other wards using Kaplan-Meier curves. Residual differences in the patients' case mix between ICUs and other wards were adjusted for utilizing multivariate Cox models. Of 13415 patients screened, 668 were critically ill. The overall infection rates (per 100 patient-days) were 1.2 for bloodstream infection (BSI) and 1.9 for urinary tract infection (UTI). The adjusted hazard ratios in ICU patients compared with patients on regular wards were 3.1 (P<0.001) for BSI and 2.5 (P<0.001) for UTI. This increased risk persisted even after adjusting for the disparity in the number of cultures sent from ICUs compared with ordinary wards. No interdepartmental differences were found in the rates of pneumonia, surgical wound infections and other infections. Minimizing the differences between characteristics of patients hospitalized in ICUs and in other wards, and controlling for the higher frequency of cultures sent from ICUs did not eliminate the increased risk of BSI and UTI associated with admission into ICUs.

High rate of candidemia in patients sustaining injuries in a bomb blast at a marketplace: a possible environmental source.

In this study, a cluster of candidemia among patients sustaining injuries in a bomb blast at a marketplace was investigated by means of a multivariate analysis, a case-control study, and quantitative air sampling. Candidemia occurred in 7 (30%) of 21 patients (58% of those admitted to the intensive care unit [ICU]) between 4 and 16 days (mean, 12 days) after the injury and was the single most frequent cause of bloodstream infections. Inhalation injury was the strongest predictor for candidemia by multivariate analysis. Candidemia among the case patients occurred at a significantly higher rate than among comparable trauma patients injured in different urban settings, including a pedestrian mall (2 of 29; P=. 02), and among contemporary ICU control patients (1 of 40; P=.001). Air sampling revealed exclusive detection of Candida species and increased mold concentration in the market in comparison with the mall environment. These findings suggest a role for an exogenous, environmental source in the development of candidemia in some trauma patients.

End-of-life decision making in the intensive care unit.

Physicians are increasingly involved in how their critically ill patients die [72]. The more this happens, the more physicians will have to understand not only how their own backgrounds and biases influence their medical management, but also the cultural and religious backgrounds of the patient and surrogate [72, 73]. The medical profession must realise that, despite tremendous advances in medical knowledge and technology, not everyone can be saved all the time, even in the area of intensive care. Physicians must understand that "doing everything" that is best for the patient may not mean starting epinephrine or performing CPR, but rather may imply moving from a process of curing to caring with palliative care [10]. This process should be initiated by discussions with the patient or surrogate, and should include knowledge of the patients' wishes as demonstrated by advance directives and durable power of attorney. The patient's code status and the intention of forgoing life-sustaining treatment should be discussed with other members of staff together with the patient and/or family in a compassionate and humane manner. The wishes of the patient and family should be taken into consideration and the physician must try to make an impartial decision by doing what is medically and ethically correct and best for this specific patient. Hopefully, in this way, a more ethical and compassionate approach to end-of-life decisions in the ICU will be obtained.

Spontaneous intracerebral hemorrhage in critically ill patients: incidence over six years and associated factors.

OBJECTIVE: Intracerebral hemorrhage (ICH) is associated with a high mortality. The present study sought to determine the incidence of spontaneous ICH in an intensive care unit (ICU) and associated factors. DESIGN: A 6 year retrospective study. SETTING: A general ICU in a university hospital. PATIENTS: All ICU patients developing ICH were included in the study. All trauma and neurosurgical patients were excluded, as well as patients who were admitted to the ICU because of ICH. MEASUREMENTS AND RESULTS: During the study period 3032 patients were hospitalized in the ICU, and 834 were excluded. The remaining 2198 patients comprised the study population. Computed tomography of the head was performed in a total of 227 patients, and the 9 patients found to have new onset ICH comprise the group of interest. None of these patients were hypertensive. Seven of the patients had either a primary hematologic malignancy or bone marrow transplantation. Eight had thrombocytopenia of <100x10(9)/l (median 10x10(9)/l, range 3-150x10(9)/l), and in 6 it preceded ICH by 5 days or more. Only in one patient were both PTT and PT prolonged. All were mechanically ventilated with high peak inspiratory pressure (PIP) (median 37 cm H2O, range 20-43 cm H2O). Arterial carbon dioxide tension (PaCO2) was considerably elevated (median 65 mm Hg, range 41-87 mm Hg). All of the patients had impaired renal and hepatic function (urea: median 14 mmol/l, range 9.9-52 mmol/l; bilirubin: median 94 micromol/l, range 20-360 micromol/l), and five had septicemia. Eight of the patients bled to other sites before they developed ICH. All patients died shortly after the diagnosis of ICH. CONCLUSIONS: Spontaneous nonhypertensive ICH is a rare, fatal event in the ICU. Associated factors include thrombocytopenia, the need for mechanical ventilation, elevated PIP and PaCO2, sepsis, and impaired hepatic and renal function.

Application of SOFA score to trauma patients. Sequential Organ Failure Assessment.

OBJECTIVE: To assess the ability of the SOFA score (Sequential Organ Failure Assessment) to describe the evolution of organ dysfunction/failure in trauma patients over time in intensive care units (ICU). DESIGN: Retrospective analysis of a prospectively collected database. SETTING: 40 ICUs in 16 countries. PATIENTS: All trauma patients admitted to the ICU in May 1995. MAIN OUTCOME MEASURES AND RESULTS: Incidence of dysfunction/failure of different organs during the first 10 days of stay and the relation between the dysfunction, outcome, and length of stay. Included in the SOFA study were 181 trauma patients (140 males and 41 females). The non-survivors were significantly older than the survivors (51 years+/-20 vs 38+/-16 years, p < 0.05) and had a higher global SOFA score on admission (8+/-4 vs 4+/-3, p < 0.05) and throughout the 10-day stay. On admission, the non-survivors had higher scores for respiratory ( > 3 in 47% of non-survivors vs 17% of survivors), cardiovascular ( > 3 in 24% of non-survivors vs 5.7% of survivors), and neurological systems ( > 4 in 41% of non-survivors vs 16% of survivors); although the trend was maintained over the whole study period, the differences were greater during the first 4-5 days. After the first 4 days, only respiratory dysfunction was significantly related to outcome. A higher SOFA score, admission to the ICU from the same hospital, and the presence of infection on admission were the three major variables associated with a longer length of stay in the ICU (additive regression coefficients: 0.85 days for each SOFA point, 4.4 for admission from the same hospital, 7.26 for infection on admission). CONCLUSIONS: The SOFA score can reliably describe organ dysfunction/ failure in trauma patients. Regular and repeated scoring may be helpful for identifying categories of patients at major risk of prolonged ICU stay or death.

Effect of haemofiltration on pathological fibrinolysis due to severe sepsis: a case report.

Bleeding due to coagulopathy is a frequent complication of severe sepsis, especially in burn patients. The primary treatment is aimed at the underlying cause but additional supportive measures, consisting mainly of coagulation factor replacement, are frequently necessary. We describe the salutary effect of continuous veno-venous haemofiltration (CVVH) with predilution on diffuse haemorrhage in a patient with severe septic shock and renal failure. The diffuse haemorrhage was initially treated with replacement of coagulation factors. Prothrombin time and partial thromboplastin time became normal while diffuse bleeding continued and the thrombelastogram showed evidence of fibrinolysis. A short period of CVVH lead to the cessation of bleeding which was reflected by a normal thrombelastogram.

Systolic pressure variation in hemodynamic monitoring after severe blast injury.

Fluid management in patients following blast injury is a major challenge. Fluid overload can exacerbate pulmonary dysfunction, whereas suboptimal resuscitation may exacerbate tissue damage. In three patients, we compared three methods of assessing volume status: central venous (CVP) and pulmonary artery occlusion (PAOP) pressures, left ventricular end-diastolic area (LVEDA) as measured by transesophageal echocardiography, and systolic pressure variation (SPV) of arterial blood pressure. All three patients were mechanically ventilated with high airway pressures (positive end-expiratory pressure 13 to 15 cm H2O, pressure control ventilation of 25 to 34 cm H2O, and I:E 2:1). Central venous pressure and PAOP were elevated in two of the patients (CVP 14 and 18 mmHg, PAOP 25 and 17 mmHg), and were within normal limits in the third (CVP 5 mmHg, PAOP 6 mmHg). Transesophageal echocardiography was performed in two patients and suggested a diagnosis of hypovolemia (LVEDA 2.3 and 2.7 cm2, shortening fraction 52% and 40%). Systolic pressure variation was elevated in all three patients (15 mmHg, 15 mmHg, and 20 mmHg), with very prominent dDown (23, 40, and 30 mmHg) and negative dUp components, thus corroborating the diagnosis of hypovolemia. Thus, in patients who are mechanically ventilated with high airway pressures, SPV may be a helpful tool in the diagnosis of hypovolemia.

Evaluation of triage decisions for intensive care admission.

OBJECTIVE: To assess physician decision-making in triage for intensive care and how judgments impact on patient survival. DESIGN: Prospective, descriptive study. SETTING: General intensive care unit, university medical center. INTERVENTIONS: All patients triaged for admission to a general intensive care unit were studied. Information was collected for the patient's age, diagnoses, surgical status, admission purpose, Acute Physiology and Chronic Health Evaluation (APACHE) II score, and mortality. The number of available beds at the time of triage and reasons for refused admission were obtained. MEASUREMENTS AND MAIN RESULTS: Of 382 patients, 290 were admitted, 92 (24%) were refused admission, and 31 were admitted at a later time. Differences between admission diagnoses were found between patients admitted or not admitted (p < .001). Patients refused admission had higher APACHE II scores (15.6+/-1.5 admitted later and 15.8+/-1.4 never admitted) than did admitted patients (12.1+/-.4; p < .001). The frequency of admitting patients decreased when the intensive care unit was full (p < .001). Multivariate analysis revealed that triage to intensive care correlated with age, a full unit, surgical status, and diagnoses. Hospital mortality was lower in admitted (14%) than in refused patients (36% admitted later and 46% never admitted; p < .01) and in admitted patients with APACHE II scores of 11 to 20 (p = .02). The 28-day survival of patients was greater for admitted patients compared with patients never admitted (p = .01). CONCLUSIONS: Physicians triage patients to intensive care based on the number of beds available, the admission diagnosis, severity of disease, age, and operative status. Admitting patients to intensive care is associated with a lower mortality rate, especially in patients with APACHE scores of 11 to 20.

Traumatic macroglossia: a life-threatening complication.

OBJECTIVE: To describe the use of muscle relaxants and a bite raiser to avoid continued tongue trauma. DESIGN: Case report. SETTING: A tertiary general intensive care unit (ICU). INTERVENTIONS: Muscle relaxation and bite raiser. MAIN RESULTS: Muscle relaxation and a bite raiser were used in a 17-yr-old male with traumatic macroglossia, which allowed for rapid resolution of edema and prevented additional trauma to the tongue. CONCLUSION: Early use of a bite raiser together with muscle relaxants allows for more rapid solution of edema and prevention of additional trauma to the tongue in patients with traumatic macroglossia.
