Evaluation of Vaso-occlusive Crisis Management With Patient-Controlled Analgesia in Children With Sickle Cell Disease
Insights
Early patient-controlled analgesia (PCA) for pediatric sickle cell disease (SCD) patients with vaso-occlusive crisis (VOC) significantly reduced pain management time and hospital length of stay (LOS). These findings suggest earlier PCA initiation improves outcomes for children with severe VOC.
Area of Science:
- Pediatric Hematology
- Pain Management
- Pharmacology
Background:
- Sickle cell disease (SCD) frequently causes vaso-occlusive crises (VOCs) in children, necessitating effective pain management.
- Patient-controlled analgesia (PCA) is a common method for managing severe pain in pediatric VOC.
- The optimal timing for initiating PCA in pediatric SCD patients with VOC remains an area for investigation.
Purpose of the Study:
- To review the utilization of PCA for pediatric patients experiencing VOC at the institution.
- To compare the impact of early versus late PCA initiation on pain relief and length of stay (LOS).
Main Methods:
- Retrospective analysis of pediatric patients treated with PCA for severe VOC between 2010 and 2016.
- Defined 'Early-PCA' as initiation within 48 hours of hospital arrival.
- Assessed time to adequate analgesia (2 consecutive pain scores <5/10 at 4-hour intervals) and LOS.
Main Results:
- 87 VOC episodes in 46 pediatric patients were analyzed; 63 received Early-PCA and 24 received Late-PCA.
- The Early-PCA group, despite higher admission pain scores, showed a shorter time to adequate analgesia (median difference: 41.0 hours).
- Early-PCA was associated with a significant reduction in LOS by a median of 3.4 days, with no increased side effects or acute chest syndrome.
Conclusions:
- Initiating PCA early in pediatric patients with severe VOC is linked to faster pain relief and shorter hospital stays.
- These findings support the early use of PCA for managing severe VOC in children.
- Further prospective studies are recommended to validate these outcomes.
Objective:
The aim of this study was to review the use of patient-controlled analgesia (PCA) in sickle cell disease (SCD) for pediatric patients with vaso-occlusive crisis (VOC) in our institution and to compare the effect of early vs late PCA start on pain relief and LOS.
Methods:
This retrospective study included all pediatric patients treated with PCA for a severe VOC from 2010 to 2016. "Early-PCA" was defined as start of PCA within 48 hours of arrival. Time to reach adequate analgesia was defined as the time to reach 2 consecutive pain scores less than 5/10 at 4-hour interval.
Results:
During the study period, 46 patients presented 87 episodes of VOC treated with PCA. Sixty-three patients with VOC were treated with Early-PCA and 24 with Late-PCA. Both groups were comparable except for median pain score at admission; the Early-PCA group had higher scores: 9.0/10 vs 7.0/10. Time to reach adequate analgesia could be evaluated only in a subset of patients (n = 32) but was shorter in the Early-PCA group with a median difference of 41.0 hours (95% CI -82.0 to -6.0). Early-PCA was associated with a median reduction in LOS of 3.4 days (95% CI -4.9 to -1.9). There was no difference between the 2 groups in terms of side effects and occurrence of acute chest syndrome during hospitalization.
Conclusions:
In this study, a reduced time to reach adequate analgesia and LOS was noted in the Early-PCA group for severe VOC. A prospective study is required to confirm these results.
