(shown in Fig. 2). It shows that the four studies were almost
symmetrically distributed in the two sides of the middle line,
and the bias was acceptable. We also noted that not all the
authors were affiliated to the Burns Department; maybe this
is a reason that the effect size was not transformed and
aggregated correctly.
Furthermore, we analysed the other effect sizes againsuch as
mortality and Gram-negative bacteraemia; the result is consis-
tent with Lin et al. [1]. However, there were only two studies
which had the same outcome as the size effect among the four;
so, the bias is inevitably increased sharply. Hence, more high-

To summarise, we conclude that glutamine supplementa-
tion significantly decreases LOS compared to controls in
critically ill patients with burns.

Letter to the Editor
Response to Letter to the Editor: Ameta-analysis of trials using the in-tention to treat principle for glutaminesupplementation in critically illpatients with burn
There are three questions in Ren et al.’s letter.
Question 1:
Ren et al. claimed that ‘‘the length of hospital stay (LOS) was described
as (mean W SD) days in the three included studies, while different as
(mean W SD) days/1%TBSA in only another included study [1]. Lin et al.
aggregated them together directly, so the result is misleading.’’
Our opinion:
We think Ren et al. held misconceptions. In Garrel’s study [1], length
of care was defined that the time from admission to the complete
healing of grafted and ungrafted wounds, including donor sites, as
determined by the surgical team. And, Garrel et al. claimed the
number of LOS day (mean W SD) was 29 W 17 and 33 W 17 for Control
and Glutamine in Table 3. These messages were self-explanatory.
Question 2:
Ren et al. claimed that the number of patients was 42 and 19 for
Control and Glutamine in Fig. 1.
Our opinion:
The clinical outcomes of the 41 patients who participated in the
study are shown in Garrel’s article.
Question 3:
Ren et al. claimed that they transformed the data to the same unit
(days) and did the analysis of this part again (the number of LOS day
was 41.16 W 37.38 and 36 W 14.18 for Control and Glutamine in Fig. 1).
Our opinion:
We don’t know how to transform those data. Would they mind giving
us any hints as to how they believe these data were transformed?

Letter to the Editor
Re: Burn Care Centres are lacking atmajor trauma centres in the UnitedKingdom
Dear Editor,
We read with interest the letter written by Mr Sammy Al-Benna
regarding burn care facilities at Major Trauma Centres in the
United Kingdom [1]. We suspect that he is rather tardy in his
comments as the burns services around the country are moving
forward significantly in ensuring the best possible burn care
provision within the Trauma Service within the NHS. We note
that in 2001 the National Burn Care Review described a structure
of Burn Care Networks ranging from burn care facilities which
provided burn services to small burn injuries provided by plastic
surgery departments to the provision of more complex burn
injuries provided by burn units and the most complex being
provided by burn centres. As every Major Trauma Centre needs
to have a Plastic Surgery Department to be compliant with its
terms of trauma provision it should be expected that every
Trauma Centre can provide appropriate burn care facilities and
treatment to the vast majority of burn injuries. A recent review
of burn cases in the South East Burns Network showed that up to
80% of burn injuries admitted to hospital could be catered for in
a burns facility rather than the more complex Burns Unit and
Burns Centre environments.
This has been taken further in the South East Burns
Network where burns facility designation has been formally
introduced to the plastic surgery services at the Major Trauma
Centres in the South East. We feel that such a process ensures
equity of access at both Major Trauma Centres and other
hospitals where plastic surgery services or burns services are
based. It also ensures that burns providers of all levels work
together and ensure that patients get treated in the right place
at the right time by the right people.
We are also keen to point out that the vast majority of burns
injuries only involve burn injury and rarely involve poly-
trauma. However, we do acknowledge the fact that appropri-
ate provision of burn care should be available and is indeed
being made available at all Major Trauma Centres.
Yours sincerely
Mr D Nikkhah
Mr B S Dheansa

Letter to the Editor
Adequate specialised burn care ser-vices are essential at major traumacentres
Sir,
It is an honour that the article entitled ‘‘Burn care facilities are
lacking at major trauma centres in England’’ [1] has aroused
the interest of Nikkah and Dheansa. It is gratifying to see their
statement of unqualified agreement that adequate burn care
and surgery services must be a key feature of all major trauma
centres. It is the obligation of clinicians to make careful,
thoughtful appraisals, and to provide balanced advice to
patients regarding the most effective treatment [2–4]. The
development of trauma networks is to be welcomed as
providing a structure of emergency care delivery within
which to offer the best chance of an optimal outcome for
most people who have a burn injury [1].
