Abstract

Background
The aim of this prospective multicenter observational study was to measure the incidence of postoperative pediatric emergence delirium and to investigate the occurrence of early postoperative negative behavior within two weeks after outpatient adenoidectomy in preschool children.

Methods
The study comprised 222 patients (1–7 years of age). All children received a multimodal anesthesia based on total intravenous anesthesia with propofol and remifentanil in combination with piritramid (0.1 mg.kg-1), ibuprofen (10 mg.kg-1), dexamethason (0.15 mg.kg-1) and ketanest S (0.1 mg.kg-1). We evaluated emergence delirium using the Pediatric Anesthesia Emergence Delirium Scale (PAED) at different predefined time points during the recovery period. Emergence delirium was defined as a PAED score ≥ 9 for the first three criteria. Additionally, we defined early postoperative negative behavior to be present when at least 5 of 27 criteria of the post hospitalization behavior questionnaire were positive.

Results
The incidence of emergence delirium following our anesthetic regime was 23%. The incidence of early postoperative negative behavior was significantly higher among patients with emergence delirium (24% vs. 11%,p =  0.04). The two categories, “sleep disturbance” and “separation anxiety”, tested within the questionnaire for early postoperative negative behavior were identified as the most common postoperative negative behavioral changes.

Conclusion
Emergence delirium not only plays a role immediately after surgery but is also linked to early postoperative negative behavior within two weeks after outpatient adenoidectomy. Parents should be informed that early postoperative negative behavior may occur in 1 out of 4 patients if emergence delirium was present postoperatively.

Resumo

Introdução

O objetivo deste estudo observacional multicêntrico prospectivo foi medir a incidência de delírio do despertar pediátrico pós-operatório e investigar a ocorrência de comportamento negativo pós-operatório precoce dentro de duas semanas após adenoidectomia ambulatorial em crianças pré-escolares.

Métodos

O estudo incluiu 222 pacientes (1 a 7 anos de idade). Todas as crianças receberam anestesia multimodal baseada em anestesia venosa total com propofol e remifentanil em combinação com piritramida (0,1 mg.kg-1), ibuprofeno (10 mg.kg-1), dexametasona (0,15 mg.kg-1) e cetaneste S. (0,1 mg.kg-1). Avaliamos o delirium ao despertar usando a Escala de Delirium de Emergência em Anestesia Pediátrica (PAED) em diferentes momentos predefinidos durante o período de recuperação. Delirium do despertar foi definido como pontuação PAED ≥ 9 para os três primeiros critérios. Além disso, definimos que o comportamento negativo pós-operatório precoce estava presente quando pelo menos 5 dos 27 critérios do questionário de comportamento pós-hospitalização eram positivos.

Resultados

A incidência de delirium do despertar após nosso regime anestésico foi de 23%. A incidência de comportamento negativo pós-operatório precoce foi significativamente maior entre pacientes com delirium do despertar (24% vs. 11%, p =  0,04). As duas categorias, “distúrbios do sono” e “ansiedade de separação”, testadas no questionário para comportamento negativo no pós-operatório imediato, foram identificadas como as alterações comportamentais negativas no pós-operatório mais comuns.

Conclusão

O delirium do despertar não apenas desempenha um papel imediatamente após a cirurgia, mas também está ligado ao comportamento negativo no pós-operatório precoce dentro de duas semanas após a adenoidectomia ambulatorial. Os pais devem ser informados de que um comportamento negativo no pós-operatório precoce pode ocorrer em 1 em cada 4 pacientes se o delirium do despertar estiver presente no pós-operatório.
