Cardiac transplantation in severely ill patients requiring intensive support in hospital

Sixty four patients were referred for cardiac transplantation from a single cardiac team at this hospital between October 1984 and December 1986. Of these patients, 33 were referred for urgent transplantation, all of whom required intensive treatment in hospital with intravenous infusions of cardiac drugs, intra-aortic balloon counterpulsation, peritoneal dialysis, ventilation, or any combination of these to sustain life. Of these 33 patients, six died while awaiting transplantation, one was removed from the waiting list for a transplant, and 26 received cardiac transplants. There were five deaths within 24 hours of operation and one death 10 days after the operation. Twenty of those who had surgery had a successful outcome of transplantation, but there was one late death 10 weeks postoperatively and a further death 31 months after surgery. Eighteen patients were alive and well 10 to 33 months (mean 19·4 months) after transplantation, with an overall survival rate after surgery of 69%.Provided that surgery can be performed before renal failure has progressed such that renal transplantation is necessary, the results are excellent (surgical survival 85·5%) and, we believe, justify the expenditure and staffing requirements necessary to treat these terminally ill patients.     

A psychotherapeutic approach to task-oriented groups of severely ill patients

This paper presents a conceptual approach for leading various types of groups of chronically mentally ill patients. Although these groups may have a concrete, task-oriented purpose, with skillful leadership they also function as psychotherapy groups. The developmental deficits in ego functions, object relations, and social skills that severely impair such groups can be compensated by non-interpretative actions of the therapists. The group leader must actively work to provide for the structure, stability, and safety of the group when group members are unable to provide these for themselves.     

Long term follow up of severely ill patients who underwent urgent cardiac transplantation.

OBJECTIVE--To assess long term survival (> 5 years) and quality of life in severely ill patients referred for urgent cardiac transplantation. SETTING--Tertiary referral centres: before transplantation at the National Heart Hospital (late 1984 to end 1986); after transplantation at Harefield Hospital. SUBJECTS--Eighteen patients (15 men; three women) who had required intensive support in hospital before cardiac transplantation and were alive at short term follow up. INTERVENTIONS--Intravenous infusions of cardiac drugs (mean 2.2 infusions), intravenous diuretics (17 patients), and many other drugs before transplantation. Intra-aortic balloon counterpulsation (four patients), temporary pacing (two), and resuscitation from cardiac arrest (three). Patients had specialised nursing care on a medical intensive care unit in almost every case. MAIN OUTCOME MEASURES--Long term survival in patients after urgent cardiac transplantation and perceived quality of life. RESULTS--Of 18 patients who were alive at short term follow up (mean (range) 19.4 (10-33) months), 14 were still alive in 1992 (69 (61-83) months). Ten still worked full time, and 11 reported no restrictions in their daily activities. Three of four patients who died in the intervening period survived > 5 years after transplantation. Overall, 17 of 18 patients survived at least 5 years. CONCLUSIONS--In severely ill patients who undergo urgent cardiac transplantation and survive in the short term, long term (5-7 year) survival and quality of life seem good.     

Human albumin administration in critically ill patients: systematic review of randomised controlled trials

Objective: To quantify effect on mortality of administering human albumin or plasma protein fraction during management of critically ill patients. Design: Systematic review of randomised controlled trials comparing administration of albumin or plasma protein fraction with no administration or with administration of crystalloid solution in critically ill patients with hypovolaemia, burns, or hypoalbuminaemia. Subjects: 30 randomised controlled trials including 1419 randomised patients. Main outcome measure: Mortality from all causes at end of follow up for each trial. Results: For each patient category the risk of death in the albumin treated group was higher than in the comparison group. For hypovolaemia the relative risk of death after albumin administration was 1.46 (95% confidence interval 0.97 to 2.22), for burns the relative risk was 2.40 (1.11 to 5.19), and for hypoalbuminaemia it was 1.69 (1.07 to 2.67). Pooled relative risk of death with albumin administration was 1.68 (1.26 to 2.23). Pooled difference in the risk of death with albumin was 6% (95% confidence interval 3% to 9%) with a fixed effects model. These data suggest that for every 17 critically ill patients treated with albumin there is one additional death. Conclusions: There is no evidence that albumin administration reduces mortality in critically ill patients with hypovolaemia, burns, or hypoalbuminaemia and a strong suggestion that it may increase mortality. These data suggest that use of human albumin in critically ill patients should be urgently reviewed and that it should not be used outside the context of rigorously conducted, randomised controlled trials.

Key messages

• Human albumin solution has been used in the treatment of critically ill patients for over 50 years
• Currently, the licensed indications for use of albumin are emergency treatment of shock, acute management of burns, and clinical situations associated with hypoproteinaemia
• Our systematic review of randomised controlled trials showed that, for each of these patient categories, the risk of death in the albumin treated group was higher than in the comparison group
• The pooled relative risk of death with albumin was 1.68 (95% confidence interval 1.26 to 2.23) and the pooled difference in the risk of death was 6% (3% to 9%) or six additional deaths for every 100 patients treated
• We consider that use of human albumin solution in critically ill patients should be urgently reviewed

     

Hypersecretion of glucagon and gastrin in severely burnt patients.

Hyperglucagonaemia and hypergastrinaemia were observed in some severely burnt patients during their illness. Hyperglucagonaemia seemed to be related to the severity of illness rather than to the burn itself, and the close correlation of glucagon concentrations with glucose and urea and its inverse correlation with bicarbonate concentrations suggest that glucagon might contribute to the hypercatabolic state. One patient developed high levels of gastrin and massive bleeding from a stress ulcer of the duodenum. Possibly gastrin hypersecretion may have a role in the pathogenesis of Curling''s ulcer.     

Effects of ambulance transport in critically ill patients.

Two groups of critically ill patients were transferred by ambulance from other hospitals to a central intensive therapy unit. The effect of transport was reviewed retrospectively in 46 patients and prospectively in 20 patients. Of the 46 patients reviewed retrospectively six became hypotensive, six became hypertensive, and seven developed delayed hypotension. One patient developed fits and six out of 13 patients had a rise in arterial PCO-2 of 1-6-4-1 kPa (12-31 mm Hg). Of the 20 patients reviewed prospectively, one patient became hypertensive due to overtransfusion, one had a fit, but none became hypotensive. Three out of four cases of delayed hypotension were related to starting intermittent positive pressure ventilation. Arterial PCO-2 fell in one patient and arterial PCO-2 rose in two, each change being related to changed oxygen therapy or narcotics. There were no changes in other cardiovascular or respiratory indices, body temperature, or urine production. Earlier transfer, resuscitation before transfer, continuing medical care during the journey, and hence a slower smoother journey seemed to be important factors in the management of these patients. Our findings, may have important implications in the future regional organization of the care of critically ill patients.     

Monitoring aminoglycoside use in patients with severely impaired renal function.

Twenty patients with severely impaired renal function, 17 of wnom had recently transplanted kidneys, were treated with aminoglycosides for severe infections acquired in hospital. Serum aminoglycoside concentrations were closely monitored and dosages adjusted individually to obtain peak and trough concentrations that ensured adequate treatment while avoiding toxicity. Causative organisms were susceptible to treatment in 21 out of 26 episodes of infection (81%), and 12 of the 17 patients (71%) in whom organisms were isolated were cured. Nephrotoxicity attributable to aminoglycosides alone was not observed during the 35 courses of treatment. Ototoxicity occurred in only one patient, who had excessively high serum concentrations of amikacin. Serum aminoglycoside concentrations were directly affected by carbenicillin and flucytosine. The concurrent administration of cephradine and cephalexin with gentamicin may have produced nephrotoxicity. We conclude that aminoglycosides, when carefully monitored, are effective and safe in patients with severely impaired renal function.     

Use of charcoal haemoperfusion in the management of severely poisoned patients.

The clinical use of uncoated charcoal haemoperfusion systems, despite their efficacy, has hitherto been prevented by the occurrence of a number of adverse effects including charcoal embolism and marked thrombocytopenia. Charcoal coated with a synthetic hydrogel overcomes many of the disadvantages associated with the use of uncoated material in that there is a much reduced thrombocytopenia and no evidence of charcoal embolism. Six patients, severely poisoned as a result of overdoses of either a barbiturate or glutethimide, were haemoperfused using such a system. Four made complete recoveries, and the two patients who died had both suffered cardiorespiratory arrests before perfusion. In contrast to haemodialysis charcoal haemoperfusion is simple to initiate, less expensive in terms of manpower and equipment, and gives superior clearance data for all barbiturates and glutethimide. We believe that this technique may have a significant role to play in the management of the severely poisoned patient.
