2941. Risk of deep-venous thrombosis after hospital discharge in patients having undergone total hip replacement: double-blind randomised comparison of enoxaparin versus placebo.
The risk of deep-vein thrombosis (DVT) and pulmonary embolism after total hip replacement (THR) surgery may persist after hospital discharge, but the extent of the risk is not known. We carried out a single-centre, prospective, randomised, double-blind trial with the aims of quantifying this risk and assessing the efficacy of continued prophylactic treatment.
2942. The effects of dopamine and adrenaline infusions on acid-base balance and systemic haemodynamics in severe infection.

Adrenaline is used increasingly in the management of septic shock, but its efficacy and safety are uncertain.
2943. Randomised, controlled trial of efficacy of midwife-managed care.

Midwife-managed programmes of care are being widely implemented although there has been little investigation of their efficacy. We have compared midwife-managed care with shared care (ie, care divided among midwives, hospital doctors, and general practitioners) in terms of clinical efficacy and women's satisfaction.
2948. Double-blind placebo-controlled study of the hyperventilation provocation test and the validity of the hyperventilation syndrome.

Hyperventilation syndrome (HVS) describes a set of somatic and psychological symptoms thought to result from episodic or chronic hyperventilation. Recognition of symptoms during the hyperventilation provocation test (HVPT) is the most widely used criterion for diagnosis of HVS. We have investigated the validity of the HVPT and of the concept of HVS.
2949. UK collaborative randomised trial of neonatal extracorporeal membrane oxygenation. UK Collaborative ECMO Trail Group.
来源: Lancet. 1996年348卷9020期75-82页
Extracorporeal membrane oxygenation (ECMO) is a complex and expensive technology that can be used to provide temporary support during respiratory failure. Its value for mature newborn infants is controversial because of varying interpretation of the available evidence. We undertook a collaborative trial throughout the UK to assess whether a policy of referral for ECMO has a beneficial effect on survival to 1 year without severe disability in comparison with conventional management.
2951. Effect of d-sotalol on mortality in patients with left ventricular dysfunction after recent and remote myocardial infarction. The SWORD Investigators. Survival With Oral d-Sotalol.

Left ventricular dysfunction after myocardial infarction is associated with an increased risk of death. Other studies have suggested that a potassium-channel blocker might reduce this risk with minimal adverse effects. We investigated whether d-sotalol, a pure potassium-channel blocker with no clinically significant beta-blocking activity, could reduce all-cause mortality in these high-risk patients.
2952. Randomised controlled trial of single BCG, repeated BCG, or combined BCG and killed Mycobacterium leprae vaccine for prevention of leprosy and tuberculosis in Malawi. Karonga Prevention Trial Group.
来源: Lancet. 1996年348卷9019期17-24页
Repeat BCG vaccination is standard practice in many countries for prevention of tuberculosis and leprosy, but its effectiveness has not been evaluated. The addition of Mycobacterium leprae antigens to BCG might improve its effectiveness against leprosy. A double-blind, randomised, controlled trial to evaluate both these procedures was carried out in Karonga District, northern Malawi, where a single BCG vaccine administered by routine health services had previously been found to afford greater than 50% protection against leprosy, but no protection against tuberculosis.
2953. Final height of short normal children treated with growth hormone.
Short-term studies have demonstrated acceleration of growth rate following administration of biosynthetic human growth hormone (r-hGH) to short normal children. We describe the effect of such treatment on final height.
2955. Effects of artemisinin derivatives on malaria transmissibility.

On the western border of Thailand the efficacy of mefloquine in the treatment of falciparum malaria has declined while gametocyte carriage rates have increased, which suggests increased transmissibility of these resistant infections. We compared the following antimalarial drugs in relation to subsequent Plasmodium falciparum gametocyte carriage: mefloquine, halofantrine, quinine, and the artemisinin derivatives.
