Insights
The On-Q pain pump effectively manages pediatric postoperative pain, reducing catheter use without impacting recovery time. This continuous local anesthesia offers an alternative to epidural catheters, minimizing associated risks.
Area of Science:
- Anesthesiology
- Pediatric Surgery
- Pain Management
Background:
- Postoperative pain management is crucial for pediatric recovery.
- Continuous local anesthesia delivery systems aim to improve pain control.
- Epidural catheters are a common method but carry inherent risks.
Purpose of the Study:
- To compare the efficacy and outcomes of the On-Q pain pump versus continuous epidural analgesia in pediatric patients.
- To evaluate pain control, catheter use, and recovery metrics.
Main Methods:
- Retrospective review of pediatric patients (2005-2008) who received either an epidural or On-Q pain pump.
- Patients were analyzed based on incision type.
Main Results:
- Both On-Q and epidural groups reported similar moderate to severe pain levels postoperatively.
- On-Q pump use was associated with decreased Foley catheter placement and shorter catheter duration.
- Supplemental narcotic use was higher in the On-Q group on postoperative day 1, particularly with abdominal incisions.
Conclusions:
- The On-Q pain pump demonstrates efficacy in pediatric postoperative pain management.
- It offers a viable alternative to epidural catheters, potentially reducing associated risks.
- Further research may explore optimal On-Q pump utilization in specific pediatric surgical populations.
Purpose:
The On-Q(®) pain pump provides a continuous infusion of local anesthesia for management of postoperative pain. The objective of this study was to assess the efficacy and outcomes of the On-Q(®) pump compared to continuous epidural in children postoperatively.
Methods:
We performed a retrospective review of patients in our hospital who received a postoperative epidural or On-Q(®) pump from 2005 to 2008. Patients were sub-categorized by incision type.
Results:
Seventy patients received epidural and 66 On-Q(®). On-Q(®) therapy was longer by 1 day (p < 0.0001), but did not affect postoperative length of stay. Patients with On-Q(®) pumps had a decreased rate of Foley catheter placement (p = 0.002) and shorter duration of catheter use by more than a day (p < 0.001). Moderate to severe pain was similar in the two groups on postoperative days 0-5. Supplemental narcotic use was higher in the On-Q(®) group only on postoperative day 1 (p = 0.005) and in patients with midline and transverse abdominal incisions. No differences were seen in time to ambulation or recovery of postoperative ileus.
Conclusion:
The On-Q(®) pain pump is an effective method for postoperative pain control, without the inherent risks of epidural catheters.

Local Anesthetics: Clinical Application as Epidural Anesthesia
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
