Abstract

Introduction

Thrombocytopenia is a
common haematological finding in critically ill patients. Studies have shown
that decreased platelet counts are associated with prolonged hospitalisation,
increased costs, and mortality in adult populations.
However,
not enough studies have investigated the incidence of thrombocytopenia and the
relationship between thrombocytopenia and the prognoses of paediatric patients
who require treatment in the intensive care unit.
We evaluated the
effects of initial platelet counts on the outcomes of.pediatric intensive care
unit patients.

Material and Methods

We performed a retrospective analysis
of the records of all patients admitted to the pediatric intensive care unit
between October 2016 and December 2017. The relationship between the initial
thrombocyte counts and the need of invasive mechanical ventilation and
non-invasive mechanical ventilation,inotropic drug use, continuous renal
replacement need, duration of hospitalization and mortality rate were
investigated.

Results

Totally 387 patients were included in
the study. Age distributions ranged from 1 month to 17 years, and the mean
patient age was 3.95±4.80 years. The most frequent diagnoses of patients were
respiratory disorders (144 patients; 37.2%). There was a statistically
significant relationship between thrombocyte levels of the first complete blood
count performed during admission and invasive mechanical ventilation, non-invasive mechanical ventilation, inotropic drug
use, mortality, acute kidney injury, and continuous renal replacement therapy.
Analyses of receiver-operator characteristic (ROC) curves for the thrombocyte
counts showed that with a cutoff value of 102,000, mortality had 92.7%
sensitivity and 53.1% specificity. The odds ratios (ORs) and relationship
between prognostic factors and thrombocytopenia were calculated using logistic
regression models. ORs were 4.616 for continuous renal replasman therapy, 6.682
for inotropic drug use, and 3.649 for mortality.

Conclusion















A low platelet count at the time of
admission to the pediatric intensive care unit should be considered an independent risk factor that
increases mortality and morbidity and prolongs hospitalisation. Extensive care
should be provided to this group of patients.

Çocuk Yoğun Bakım Ünitesinde Başvuru Trombosit Değerinin Hasta Sağkalımına Etkisi

Abstract

Giriş

Trombositopeni,
kritik hastalardaki ortak bir hematolojik bulgudur. Araştırmalar, trombosit
sayısındaki azalmanın, hastanede yatış süresinin uzaması, artan maliyetler ve
yetişkin popülasyonunda mortalite ile ilişkili olduğunu göstermiştir. Ancak,
trombositopeninin görülme sıklığını ve trombositopeni ile yoğun bakım
ünitesinde tedavi gerektiren pediatrik hastaların prognozları arasındaki
ilişkiyi araştıran yeterli çalışma yoktur. Başvuru trombosit sayısının çocuk
yoğun bakım ünitesi hastalarındaki sonuçlarını değerlendirdik.

Gereç ve yöntemler

Çocuk
yoğun bakım ünitesine Ekim 2016 - Aralık 2017 tarihleri ​​arasında başvuran tüm
hastaların kayıtlarının geriye dönük olarak inceledik. Başvuru trombosit
sayıları ile invaziv mekanik ventilasyon ihtiyacı ve non-invaziv mekanik
ventilasyon ihtiyacı, inotropik ilaç kullanımı arasındaki ilişki, sürekli renal
replasman ihtiyacı, hastanede yatış süresi ve mortalite oranları araştırıldı.

Sonuçlar

Çalışmaya
toplam 387 hasta dahil edildi. Yaş dağılımları 1 ay ile 17 yıl arasında
değişmekte olup, ortalama hasta yaşı 3,95 ± 4,80 idi. Hastaların en sık başvuru
tanısı solunum sıkıntısı idi (144 hasta;% 37.2). Başvuru sırasındaki ilk tam
kan sayımı trombosit seviyeleri ile invaziv mekanik ventilasyon, invaziv olmayan
mekanik ventilasyon, inotropik ilaç kullanımı, mortalite, akut böbrek hasarı ve
sürekli böbrek replasman tedavisi arasında istatistiksel olarak anlamlı bir
ilişki vardı. Trombosit sayısı için receiver-operator characteristic (ROC)
eğrilerinin analizi, 102.000'lik bir kesim değerinde ölüm oranının% 92.7
duyarlılığa ve% 53.1 özgüllüğe sahip olduğunu göstermiştir. Odds oranları
(OR'ler), prognostik faktörler ve trombositopeni ile arasındaki ilişki lojistik
regresyon modelleri kullanılarak hesaplandı. ORs sürekli renal replasman
tedavisi için 4.616, inotropik ilaç kullanımı için 6.682 ve mortalite için
3.649 idi.

Sonuç















Çocuk
yoğun bakıma yatış sırasındaki düşük trombosit sayısı, mortalite ve morbiditeyi
artıran ve hastanede yatış süresini uzatan bağımsız bir risk faktörü olarak
düşünülmelidir. Bu hasta grubuna daha yakın izlem yapılmalıdır.

The publication language of Turkish Journal of Pediatric Disease is English.


Manuscripts submitted to the Turkish Journal of Pediatric Disease will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in the field, in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions. Articles accepted for publication in the Turkish Journal of Pediatrics are put in the order of publication, with at least 6 original articles in each issue, taking into account the acceptance dates. If the articles sent to the reviewers for evaluation are assessed as a senior for publication by the reviewers, the section editor and the editor considering all aspects (originality, high scientific quality and citation potential), it receives publication priority in addition to the articles assigned for the next issue.


The aim of the Turkish Journal of Pediatrics is to publish high-quality original research articles that will contribute to the international literature in the field of general pediatric health and diseases and its sub-branches. It also publishes editorial opinions, letters to the editor, reviews, case reports, book reviews, comments on previously published articles, meeting and conference proceedings, announcements, and biography. In addition to the field of child health and diseases, the journal also includes articles prepared in fields such as surgery, dentistry, public health, nutrition and dietetics, social services, human genetics, basic sciences, psychology, psychiatry, educational sciences, sociology and nursing, provided that they are related to this field. can be published.
