37 patients, over the age of 65 years, with a femoral neck fracture who were scheduled for operative fixation, were randomized to a preoperative IV dose of either dexamethasone 0.1mh/kg or placebo. The purpose of this study was to determine if preoperative dexamethasone led to a significant reduction in pain and opioid consumption over the first 3 days and 1 week after surgery. Scores for pain at rest were significantly lower in the dexamethasone group compared to the placebo group at 6 hours, and morphine consumption within the first 24 hours was significantly lower in the dexamethasone group compared to the placebo group. The difference between groups in pain scores on movement did not reach significance, and no significant differences in either pain comparison were found at subsequent follow-up time points.

O Índice de Fragilidade é uma ferramenta que auxilia na interpretação de achados significativos, fornecendo uma medida de força para um resultado. O Índice de Fragilidade representa o número de eventos consecutivos que precisam de ser adicionados a um resultado dicotómico para que o resultado deixe de ser significativo. Um número pequeno representa um resultado mais fraco e um número grande representa um resultado mais forte.
Porque é que este estudo era necessário agora?
Femoral neck fractures are common among elderly patients presenting with trauma, necessitating surgical fixation. Preoperative low-dose dexamethasone has been suggested as a possible addition to multimodal analgesia regimens to improve postoperative analgesic efficacy. However, there have been concerns expressed relating to a possible increase in adverse events, particularly in such an age group.
Qual era a principal questão de investigação?
In the fixation of femoral neck fractures, does a preoperative IV dose of dexamethasone 0.1mg/kg result in significantly lower pain scores at 6 hours postoperatively when compared to placebo saline?
- At 6 hours, NRS pain at rest scores was significantly lower in the dexamethasone group (0.8+/-1.3) compared to the placebo group (3.9+/-2.9) (p=0.0004). The difference in NRS pain on movement between the dexamethasone group (3.2+/-2.6) and placebo group (5.5+/-3.8) did not reach statistical significance (p=0.055).
- No significant differences between groups in NRS pain at rest or on movement were reported from 12h to 1 week postoperatively.
- Cumulative 24h morphine consumption was significantly lower in the dexamethasone group (7.7+/-8.3mg) compared to the placebo group (15.1+/-9.4mg) (p=0.04).
- The incidence of postoperative nausea/vomiting, sedation, and pruritus were reported to not significantly differ between groups.
De que é que me devo lembrar mais?
In the operative fixation of a femoral neck fracture in those 65 years of age or older, the use of a preoperative dose of dexamethasone 0.1mg/kg demonstrated significantly reduced pain at rest for the first 6 hours after surgery, and significantly lower opioid consumption for the first 24 hours after surgery. Differences between groups at subsequent time points were not significant, nor was pain during movement at any time point.
Como é que isto afectará o tratamento dos meus doentes?
The results of this study suggest that an IV dose (0.1mg/kg) of dexamethasone prior to fixation of a femoral neck fracture may be beneficial for early pain management in older patients. Nevertheless, pain rebounded beyond 6 hours and was similar to placebo for the remainder of the follow-up period. Therefore, the use of a postoperative dexamethasone dose in multimodal analgesia regimens should be considered for investigation in future trials. Additionally, the sample size of the current study was quite small, limiting the strength of the obtained results. Larger trials are needed to confirm the findings of the current study.
