Insights
Delayed referral of pediatric burn patients requires higher ketamine doses for pain management. Early, adequate analgesia is crucial from the time of injury to improve outcomes.
Area of Science:
- Pediatric Burn Care
- Pain Management
- Anesthesiology
Background:
- Delayed referrals may lead to increased analgesia needs in pediatric burn patients.
- Previous studies indicated poor analgesia protocol adherence in district hospitals.
- Inadequate background and procedural analgesia might contribute to higher requirements.
Purpose of the Study:
- To compare ketamine analgesia requirements for dressing changes in acute versus delayed pediatric burn referrals.
- To investigate if delayed referral ( > 21 days post-injury) correlates with higher ketamine doses.
- To analyze ketamine use considering length of stay and total body surface area (TBSA) burns.
Main Methods:
- Retrospective review of pediatric patients (<12 years) admitted to Pietermaritzburg Burn Service (July 2017-June 2018).
- Analysis of total ketamine dose, patient weight, admission days, and TBSA.
- Calculation of ketamine use per kg per day admitted per TBSA (mg/kg/days admitted/TBSA).
Main Results:
- 197 patients were analyzed, divided into acute (<21 days) and delayed (≥21 days) referral groups.
- Delayed referral group (30 patients) showed a statistically significant higher median ketamine dose (0.41 mg/kg/days admitted/TBSA) compared to the acute group (167 patients, 0.27 mg/kg/days admitted/TBSA) (p=0.01).
- The difference in ketamine requirements was significant when adjusted for length of stay and TBSA.
Conclusions:
- Pediatric burn patients with delayed referrals necessitate higher ketamine doses for effective procedural analgesia.
- Inadequate pain management during the acute burn phase may necessitate increased analgesia later.
- Emphasizes the critical importance of providing sufficient analgesia from the initial injury stage.
Background:
Our clinical impression is that delayed referrals require more analgesia than children referred to our service acutely. Previous work demonstrated poor uptake of analgesia protocols at district hospitals with probable inadequate background and procedural analgesia, which may account for this. The purpose of this study was to compare analgesia requirements for dressing changes of paediatric patients referred to us acutely versus those children with delayed referral (i.e. more than 21 days post injury). Our hypothesis is that paediatric patients with delayed referral require higher doses of ketamine when taking length of stay and total body surface area (TBSA) of the burn into account.
Methods:
Data for children under 12 years, admitted to the Pietermaritzburg Burn Service (PBS) from the 1 July 2017 until 30 June 2018 was reviewed. Total ketamine dose during admission, weight, days admitted and TBSA were analysed. The total ketamine use in milligram per kilogram per days admitted per TBSA (mg/kg/days admitted/TBSA) was calculated. Statistical analysis was performed to compare the total ketamine dose between the acute and delayed referral groups.
Results:
One-hundred-and-ninety-seven patients were included. Patients were divided into two groups, the acute group including those referred to the PBS early (prior to 21 days post-burn) and the delayed referral group (those referred 21 days or more post burn). The acute group consisted of 167 patients and the chronic group 30 patients. There is a statistically significant difference between the total ketamine dose (mg/kg/days admitted/TBSA) for the acute referral and delayed referral groups (p = 0.01). The median total ketamine dose (mg/kg/days admitted/TBSA) of the acute referral group was 0.27 (Range: 0-7.05) and the median total Ketamine dose (mg/kg/days admitted/TBSA) for the delayed referral group was 0.41 (range: 0.1-3.89).
Conclusion:
Patients with delayed referrals require more ketamine to achieve adequate procedural analgesia than patients referred acutely. Inadequate analgesia in the acute phase of the burn may influence this, underpinning the importance of adequate analgesia right from the time of the injury.
