Insights
Severe acute postoperative pain is common in children after hospital discharge. Preoperative anxiety, severe pain before surgery, and undergoing multiple procedures increase this risk.
Area of Science:
- Pediatric Anesthesiology
- Pain Management
- Surgical Outcomes
Background:
- Postoperative pain is a significant concern in pediatric ambulatory surgery.
- Assessing pain after hospital discharge is crucial for patient recovery.
- Risk factors for severe pain require further investigation.
Purpose of the Study:
- To determine the incidence of severe acute postoperative pain in children on the first day after hospital discharge.
- To identify risk factors associated with severe postoperative pain in this population.
Main Methods:
- A cohort study involving 279 children (5-12 years) undergoing ambulatory surgery in Brazil.
- Pain assessment using the Faces Pain Scale-Revised at pre-surgery, immediate postoperative, and first postoperative day.
- Cox regression analysis to identify risk factors for severe postoperative pain (defined as score ≥6).
Main Results:
- The incidence of severe postoperative pain on the first day after discharge was 15.8%.
- Preoperative anxiety (HR=2.23), severe preoperative pain (HR=2.78), and undergoing two surgical procedures (HR=2.91) were significantly associated with severe postoperative pain.
Conclusions:
- A high incidence of severe acute postoperative pain was observed in children post-discharge.
- Preoperative anxiety, severe preoperative pain, and multiple surgical procedures are confirmed risk factors for severe postoperative pain.
Objectives:
to estimate the incidence and the risk factors for severe acute postoperative pain self-reported on the first day after hospital discharge.
Methods:
cohort study with 279 children from both sexes (5-12 years old), indicated for ambulatory surgery in two Brazilian hospitals. Children were assessed at the pre-surgery, immediate postoperative and first postoperative day. Faces Pain Scale-Revised and Yale Preoperative Anxiety Scale Modified were used. Severe postoperative pain was defined as score ≥6. Cox regression analyses were used.
Results:
the incidence of severe postoperative pain was 15.8% (95%CI:10.7%-20.4%) on the first postoperative day. Preoperative anxiety (HR=2.23; p=0.049), severe preoperative pain (HR=2.78; p=0.031) and having undergone two surgical procedures (HR=2.91; p=0.002) were associated with severe postoperative pain.
Conclusions:
the incidence of severe postoperative pain self-reported after hospital discharge was high. Anxiety and severe preoperative pain, in addition to performing two surgical procedures at the same time were confirmed as risk factors.
