    Notes: Herbage characteristics were studied over years 4–6 (1988–90) in three perennial ryegrass (Lolium perenne L.) varieties as grass-only (200 kg N ha-1) and grass/clover (Trifolium repens L.) swards which received 75kg N ha-1 in 1988 and 0kg N ha-1 in 1989 and 1990 when continuously stocked with sheep. Mean total annual herbage production of Aurora, a very early flowering variety, was 11% more than that of late-flowering Aberystwyth S23 due to 21% higher growth as grass/clover pasture. The grass/clover sward of Meltra, a tetraploid late-flowering variety, out-yielded S23/clover by 17%. Herbage production of grass/clover was 86% of that of grass only in 1988 but only 54% of the grass-only swards averaged for 1989 and 1990. In vitro organic matter digestibility (OMD) of Meltra was 38g kg-1 OM and 27g kg-1 OM higher than that of S23 and Aurora respectively. OMD of grass/clover was 15g kg-1 OM higher than that of grass only during the post-weaning period. Herbage intake was positively correlated with OMD of herbage.The herbage attributes were related to lamb performance reported previously. Lamb output was positively correlated with intake of digestible organic matter.Differences between the three varieties in herbage characteristics were greater as grass/clover than as grass-only swards, reflecting their compatibility with white clover. In this respect Meltra was the best and S23 the poorest variety.

    Notes: Relative sheep production from Aurora (very early flowering), Mellra (late-flowering tetraploid) and Aberystwyth S23 (late flowering) perennial ryegrass (Lolium perenne L.) varieties was compared during harvest years 4-6 (1988-90) as grass only (200 kg N ha−1) and grass/clover (75 kg N ha −1 in 1988, 0 kg N ha−1 in 1989 and 1990) at Bronydd Mawr Research Centre (310-363 m) in mid-Wales. The pastures were continuously stocked with Beulah Speckled Face ewes and their Suffolk cross lambs from spring to mid-July. From late July to early November only the weaned lambs grazed the swards.Mean (1988-90) total annual lamb production per hectare from Aurora and Meltra was 70% and 16% more than that from S23. However, the difference between both varieties and S23 was much greater as grass/clover (Aberystwyth S184 small-leaved type) than as grass-only swards. Differences between the grasses in individual lamb growth rates were most pronounced during the post-weaning period, when that on Meltra was 38% and 23% more than on Aurora and S23 respectively.Mean annual lamb output from grass/clover swards was only 70% of that from grass-only swards during the 2 years when the former swards received no fertilizer N. Averaged over the 3 years (1988-90) individual lamb liveweight gain post weaning was 38% higher on grass/clover than on grass-only swards.The results are discussed in relation to those for the first 3 harvest years (1985-87). It is concluded that, although Aurora was less persistent than both late-flowering varieties, its superiority in providing an average of 29% more lamb output than S23 during the critical spring period (up to early June) would be of considerable practical significance in upland sheep systems, as would be the overall superiority of the tetraploid Meltra over S23.

    Notes: In a scientific discussion of the processes which we (or some of us) designate “vital,” attention is concentrated on an interpretation of that which happens within a relational system of physical influence. In a scientific discussion of the processes which we reflectively distinguish as “mental,” attention is directed to what occurs in a relational system of psychological reference. We should seek to distinguish each from the other in any given context where both are in evidence.

    Notes: The outcome of adult respiratory distress syndrome complicating cardiopulmonary bypass has changed little in recent years. A retrospective, case-controlled study was designed to assess the incidence of the adult respiratory distress syndrome in these circumstances and the extent to which it could be linked with pre and peri-operative predictive factors. Eleven patients who developed the syndrome out of 840 who underwent cardiopulmonary bypass over a 9 month period were compared with 53 controls matched for sex, operation and surgeon. The incidence of adult respiratory distress syndrome and its mortality were 1.3% and 53% respectively. Significant predictors were a high intra and postoperative intervention score, the total volume of blood pumped during bypass (〉300 l) and age (〉60 years). These risk factors should alert the clinician to the possibility of severe postoperative pulmonary complications.

    Blood lactate and mixed venous-arterial PCO2 gradient as indices of poor peripheral perfusion following cardiopulmonary bypass surgry (1991)

    Notes: Abstract Conventional indices of tissue perfusion after surgery involving cardiopulmonary bypass (CPB) may not accurately reflect disordered cell metabolism. Venous hypercarbia leading to an increased veno-arterial difference in CO2 tensions (V-aCO2 gradient) has been shown to reflect critical reductions in systemic and pulmonary blood flow that occur during cardiorespiratory arrest and septic shock. We therefore measured plasma lactate levels and V-aCO2 gradients in 10 patients (mean age 57.2 years) following CPB and compared them with conventional indices of tissue perfusion. Plasma lactate levels, cardiac index (CI) and oxygen uptake $$(\dot VO_2 )$$ all increased significantly (p〈0.05 vs baseline levels) up to 3h following surgery. Oxygen delivery $$(\dot DO_2 )$$ did not change. Plasma lactate levels correlated significantly with CI (r=0.47,p〈0.01). V-aCO2 fell significantly with time (p〈0.01 vs baseline). There was an inverse relationship between V-aCO2 and cardiac index and V-aCO2 and lactate (r=−0.37,p〈0.05;r=−0.3,p〈0.05 respectively). We conclude that blood lactate, CI and $$\dot VO_2 $$ increase progressively following CPB. An increase in lactate was associated with a decrease in V-aCO2. An increase in V-aCO2 was not therefore associated with evidence of inadequate tissue perfusion as indicated by an increased blood lactate concentration.

    The use of radionuclide techniques in the assessment of alveolar-capillary membrane permeability on the intensive care unit (1990)

    Notes: Conclusion Three isotopic methods of estimating alveolar-capillary membrane permeability have been described. The first, radiolabelled HSA, is crude, and appears to have no clinical applications. Pulmonary99mTc-DTPA clearance studies are relatively easy to perform, but suffer from their high sensitivity and variations in technique from centre to centre. The double isotopic measurement of PAI has only been adopted by a few centres, but may offer reliable assessment of the pulmonary endothelial permeability which is probably an early marker of acute lung injury. None of these techniques has proved predictive of outcome in ARDS. However, trials where alveolar-capillary membrane permeability is assessed before clinical evidence of lung injury is apparent have yet to be conducted. Thus at present, methods of assessing alveolar-capillary membrane permeability, particularly capillary endothelial integrity, may prove to be more useful in monitoring new therapeutic interventions in lung injury, rather predicting outcome.

    Continuous veno-venous haemofiltration following cardio-pulmonary bypass (1993)

    Notes: Abstract Objective To study the impact of continuous veno-venous haemofiltration on survival in patients with acute renal failure (ARF) following cardio-pulmonary bypass (CPB) surgery. Design A retrospective study of all patients requiring haemofiltration after CPB over a 2 year period. Setting A 20 bedded, adult cardothoracic intensive care unit in a postgraduate teaching hospital. Patients 35 patients (26 male, age range 24–74 years) required haemofiltration (2.7% of the total number of patients undergoing CPB). Main results Cardiovascular failure post CPB was the commonest causes of ARF (n=16). Indications for haemofiltration were ureamia (21), oligo-anuria (11), volume overload (2) and hyperkalaemia (1). Mean time from CPB to the initiation of haemofiltration was 8 days (range 0–15 days). Mean urea was 30 mmol/l and creatinine 362 μmol/l immediately prior to treatment. Urea was well-controlled in all patients, although 2 needed haemodiafiltration. Twenty-six patients died during their admission to the ICU (74% mortality). A further 3 patients died during their hospital admission, following discharge from ICU. Outcome was particularly poor in patients with cardiovascular failure following CPB (16 cases, 0 survivors). Survivors tended to commence filtration earlier (mean of 4 vs 7 days for non-survivors) and required treatment for a mean period of 8 days (range 1–26 days). Survival was determined by the number of failed organ systems at the start of haemofiltration. Thus, 100% of patients with single system failure survived, compared to only 10% with 3 or more system failure. Conclusions Despite the theoretical advantages of haemofiltration and the effective control of uraemia the mortality associated with ARF following CPB remains high and is probably determined by the number of failed organs systems.
