Abstract
Background and objective
Procedural
pain in neonates has been a concern in the last two decades. The
purpose of this review was to provide a critical appraisal and a
synthesis of the published epidemiological studies about procedural pain
in neonates admitted to intensive care units. The aims were to
determine the frequency of painful procedures and pain management
interventions as well as to identify their predictors.
Databases and data treatment
Academic
Search, CINAHL, LILACS, Medic Latina, MEDLINE and SciELO databases were
searched for observational studies on procedural pain in neonates
admitted to intensive care units. Studies in which neonatal data could
not be extracted from the paediatric population were excluded.
Results
Eighteen
studies were included in the review. Six studies with the same study
duration, the first 14 days of the neonate life or admission in the
unit of care, identified 6832 to 42,413 invasive procedures, with an
average of 7.5–17.3 per neonate per day. The most frequent procedures
were heel lance, suctioning, venepuncture and insertion of peripheral
venous catheter. Pharmacological and nonpharmacological approaches were
inconsistently applied. Predictors of the frequency of procedures and
analgesic use included the neonate's clinical condition, day of unit
stay, type of procedure, parental presence and pain assessment. The
existence of pain protocols was not a predictor of analgesia.
Conclusions
Painful
procedures were performed frequently and often with inadequate pain
management. Unlike neonate clinical factors, organizational factors may
be modified to promote a context of care more favourable to pain
management.
