Update in the management of critically ill burned patients

Effect of albumin substitution on pharmacokinetics of piperacillin/tazobactam in patients with severe burn injury admitted to the ICU

BACKGROUND

Pathophysiological changes in severely burned patients alter the pharmacokinetics (PK) of anti-infective agents, potentially leading to subtherapeutic concentrations at the target site. Albumin supplementation, to support fluid resuscitation, may affect pharmacokinetic properties by binding drugs. This study aimed to investigate the PK of piperacillin/tazobactam in burn patients admitted to the ICU before and after albumin substitution as total and unbound concentrations in plasma.

PATIENTS AND METHODS

Patients admitted to the ICU and scheduled for 4.5 g piperacillin/tazobactam administration and 200 mL of 20% albumin substitution as part of clinical routine were included. Patients underwent IV microdialysis, and simultaneous arterial plasma sampling, at baseline and multiple timepoints after drug administration. PK analysis of total and unbound drug concentrations under steady-state conditions was performed before and after albumin supplementation.

RESULTS

A total of seven patients with second- to third-degree burns involving 20%-60% of the total body surface were enrolled. Mean (SD) AUC0-8 (h·mg/L) of total piperacillin/tazobactam before and after albumin substitution were 402.1 (242)/53.2 (27) and 521.8 (363)/59.7 (32), respectively. Unbound mean AUC0-8 before and after albumin supplementation were 398.9 (204)/54.5 (25) and 456.4 (439)/64.5 (82), respectively.

CONCLUSIONS

Albumin supplementation had little impact on the PK of piperacillin/tazobactam. After albumin supplementation, there was a numerical increase in mean AUC0-8 of total and unbound piperacillin/tazobactam, whereas similar Cmax values were observed. Future studies may investigate the effect of albumin supplementation on drugs with a higher plasma protein binding.

Effect of physical therapy rehabilitation program combined with music on children with lower limb burns: A twelve-week randomized controlled study

BACKGROUND

Burn injuries cause significant physical impairments that need comprehensive rehabilitation and coordination with the acute burn care team. Music had been shown to increase positive mood during exercise, which may result in motivation for participation in exercise programs. The current study aimed to evaluate the effect of physical therapy rehabilitation program combined with music therapy on children with lower limb burns.

METHODS

A twelve-week randomized controlled study including thirty pediatrics with lower limb burns. They were randomly assigned into two equal groups, 15 children per each. Group A received a physical therapy rehabilitation program combined with music therapy in addition to routine medical care. However, Group B received a physical therapy rehabilitation program without music therapy. Assessment of pain was by visual analogue scale (VAS), assessment of the range of motion (ROM) by goniometer, and gait assessed by GAIT Rite. The evaluation was carried before and after the interventions.

RESULTS

Before starting the study, no significant differences were detected between the two study groups (p < 0.05). The study results reported statistically significant improvement in VAS, ROM, and GAIT Rite in both groups after the intervention (p < 0.05). Group A showed greater improvement than group B in all outcome measures (p < 0.05).

CONCLUSION

Physical therapy program combined with music therapy is an effective and safe modality for improving pain, range of motion, and gait parameters in pediatrics with lower limb burn. Also, physical therapy combined with music therapy is more effective than physical therapy alone in the treatment of pediatrics with lower limb burns.

The effects of music intervention on burn patients during treatment procedures: a systematic review and meta-analysis of randomized controlled trials

Background

The treatment of burn patients is very challenging because burn injuries are one of the most severe traumas that can be experienced. The effect of music therapy on burn patients has been widely reported, but the results have been inconsistent. Thus, we performed a systematic review and meta-analysis of randomized controlled trials in burn patients to determine the effect of music during treatments.

Methods

We searched a variety of electronic databases, including MEDLINE (via PubMed), EMBASE, Cochrane Library, Psychinfo, VIP Database for Chinese Technical Periodicals (VIP) and China National Knowledge Infrastructure (CNKI) for relevant trials on the basis of predetermined eligibility criteria. from their first available date through February 2016. Our search focused on two key concepts: music interventions (including music, music therapy and music medicine) and physical activity outcomes (including pain, anxiety, burn characteristics, dressing changes, wound care, debridement and rehabilitation). Two reviewers independently screened records and extracted data from all eligible studies. Statistical heterogeneity was determined using Q-test and the I² statistic. The endpoints included standardized mean differences (SMDs) and 95% confidence intervals (CIs). Publication bias was tested by Begg’s funnel plot and Egger’s test.

Results

A total of 17 studies met the inclusion criteria, for a total of 804 patients. A statistically significant difference in pain relief was demonstrated between music and non-music interventions (SMD = −1.26, 95% CI [−1.83, −0.68]), indicating that music intervention has a positive effect on pain alleviation for burn patients. The results indicated that music interventions markedly reduced anxiety in individuals compared to non-music interventions (SMD = −1.22, 95% CI [−1.75, −0.69]). Correspondingly, heart rate decreases were found after treatments that included music interventions (SMD = −0.60, 95% CI [−0.84, −0.36]).

Conclusion

In summary, a positive correlation was found between treatments including music interventions and pain alleviation, anxiety relief, and heart rate reduction in burn patients. However, additional high-quality studies with carefully considered music interventions for burn patients are still needed.
