    Notes: Abstract. Cyclooxygenase (COX)-2 is the predominant COX isoform present at sites of inflammation, and produces prostaglandins (PG) that cause swelling and pain. However, in situations where the release of protective PGs by COX-1 has been lost, the induction of COX-2 may compensate and reduce inflammatory responses. This is particularly likely in large blood vessels, where, under physiological conditions, the release of prostacyclin by COX-1, present in the endothelium, is an important component of cardiovascular homeostasis. We, and others, have recently shown that COX-2 can be induced by proinflammatory cytokines in human blood vessels, and also in human airway cells. Moreover, recent data from our group have suggested that in these structures, COX-2 is anti-inflammatory at the level of cellular proliferation, adhesion receptor expression, and cytokine release.

    Notes: Summary No measurement of myocardial performance currently available in the ICU can be regarded is ideal. Table 2 summarises the main features of the major monitoring techniques. As many of the indices of myocardial performance are interdependent, quantifying the contribution of each component to overall cardiac function is not possible currently, and the clinical utility of monitoring each individually is not therefore established. Bedside measurements of LV dimensions, volumes and ejection fraction, and the other indices of systolic and diastolic function can now be made, but the case for their routine use in influencing clinical practice remains unproven. Transoesophageal echocardiography has an important and established diagnostic role and has been used successfully for continuous monitoring during surgery, but practical considerations seriously limit its potential for routine use. Radionuclide techniques allow the measurement of many of the same parameters and have the potential for continuous use, but practical problems and the additional risk of radiation exposure may limit this application in the critical care environment. Doppler techniques are non-invasive, provide continuous data and are simple to operate, but the data provided has important limitations. Although the pulmonary artery catheter has been in use for over twenty years, questions regarding the information is provides concerning myocardial function remain and the extent to which it should influence therapeutic decisions is still controversial. However with the development of additional facilities, particularly the continuous measurement of cardiac output the pulmonary artery catheter seems likely to remain the mainstay of bedside monitoring of myocardial performance in the critically ill in the immediate future.

    Notes: Abstract Objective: To compare the effects of dopexamine and dopamine on the mucosal permeability of the gastrointestinal tract (GIT). Design: Prospective, randomised clinical trial. Setting: Intensive care unit of a postgraduate teaching hospital, London, England. Patients: Thirty patients undergoing elective surgery involving cardiopulmonary bypass, performed by a single surgeon. Interventions: Patients were randomly assigned to receive either dopexamine 2.0 μg/kg per min or dopamine 2.5 μg/kg per min for the duration of the study period. Measurements and main results: Hemodynamic parameters and gastric intramucosal pH (pHi) were measured at intervals throughout the study. GIT permeability was measured once, post-operatively, using the ratio of absorbed lactulose to L-rhamnose. The groups were similar with respect to demographics, pre- and post-operative risk factors. The lactulose/rhamnose ratio was (mean ± SEM) 0.44 ± 0.10 in the dopexamine group vs 0.65 ± 0.08 in that receiving dopamine (p 〈 0.05). The dopexamine group had a significantly higher oxygen delivery preoperatively (479.5 ± 32.0 ml/min per m2 vs 344.4 ± 23.9 ml/min per m2 for dopamine, p 〈 0.01), but no other significant differences emerged between the groups. Conclusions: Compared to dopamine, dopexamine reduces GIT permeability following surgery involving cardiopulmonary bypass. The mechanism of this effect remains unclear.

    Notes: Abstract Objective: To assess plasma iron status in critically ill patients with septic shock. Design: Observational, prospective study. Setting: Adult intensive care units in teaching and tertiary referral hospitals. Patients and participants: Fifteen adult patients with established septic shock. Normal control subjects (n = 10) were also investigated. Data from patients and controls were compared with previously published iron values in critical care patients. Measurements and results: The indices investigated and correlated with clinical scores of illness severity included bleomycin-detectable iron, non-haem iron; transferrin and its percentage iron saturation, and the iron binding (anti-oxidant) activity of transferrin. Bleomycin-detectable iron was not present in the plasma of patients with septic shock whilst the plasma transferrin remained unsaturated with iron. One patient in multi-organ failure displayed bleomycin-detectable iron in plasma (1.16 μmol/l) and had 100 % iron-saturation of transferrin. The plasma non-haem iron levels (7.84 ± 1.82 μmol/l) were the lowest of all critical care patient groups studied by us. The plasma transferrin levels were also low but resulted in a near normal percentage saturation of transferrin with iron (34.6 ± 6.5 %). The scores of clinical severity correlated with changes in plasma iron chemistry. Conclusions: Patients with septic shock rarely have iron saturated transferrin in their plasma leading to the presence of bleomycin-detectable iron.
