Safety of topical administration of nasal decongestants and vasoconstrictors in paediatric nasal surgery - A systematic review

OBJECTIVES

Topical intranasal decongestants are essential in nasal surgery to improve operative field. There are concerns regarding safety in paediatric population. Data on safety and safe dosage are limited. This systematic review evaluated the literature on safety and dosage of intranasal decongestant in paediatric population.

METHODS

We performed a systematic search of PubMed, EMBASE, Cochrane library for relevant articles. Quality assessment was done on included articles.

RESULTS

A total of 10 articles were included: five case reports; three observational studies; and two randomised control trials. Decongestants evaluated were phenylephrine, oxymetazoline, epinephrine, xylometazoline, and cocaine. In total, 209 patients were included. Side effects reported included bradycardia, tachycardia and hypertension. These were mostly self-limiting and of no clinical compromise to the patients. A total of 4/209 (1.9%) of patients required treatment for these reported effects. No mortality was reported in the included studies.

CONCLUSION

In the paediatric population, the literature suggests that when delivered in a pre-specified, controlled dosage, the haemodynamic effects of phenylephrine, oxymetazoline, xylometazoline are minimal and of no clinical significance. There is scope for further studies to establish safe dosage in the paediatric population given the paucity of current literature.

965 Complication Rates in Operatively Managed Ankle Fracture/Dislocations - The Effect of Pre-Reduction Imaging and Compliance with BOAST 12 Guidance

Aim

The BOAST-12 guidelines for the management of ankle fractures aims to optimise functional recovery and reduce complications. They advise against having radiographs prior to urgent reduction of clinically deformed ankles as it could cause an unacceptable delay to subsequent management. Our study aimed to assess the effect of time to acceptable reduction on the risk of complications and time to definitive reduction.

Method

This was a retrospective observational study of patients with ankle fracture-dislocations between 2013 to 2017 at the Northern General Hospital’s Emergency Department (ED). Information collected from 2 patient groups (with and without pre-reduction radiographs), included patient demographics, time to accepted reduction, number of manipulations, operations, and subsequent complications.

Results

242 patients were identified. Time from arrival in ED to acceptable reduction was significantly longer in patients with pre-reduction radiographs versus patients without (184.5 vs 82 minutes, p < 0.00), but did not increase the overall risk of complications (p = 0.62). Pre-reduction radiographs were associated with insignificantly higher rates of post-traumatic osteoarthritis (p = 0.17) and slightly longer wait time for definitive intervention (1 vs 2 days, p = 0.72). However, this had no relationship with the number of manipulations (p = 0.53).

Conclusions

The use of pre-reduction radiographs significantly increased time to acceptable reduction of ankle fracture-dislocations. However, this was not associated with increased risk of complications or time to definitive management.

Functional Outcomes Following Operative and Nonoperative Management of Weber C Ankle Fractures: A Systematic Review

Weber C ankle fractures are unstable ankle fractures occurring above the syndesmosis. These fractures are often managed operatively, although a small population of patients are still selected for nonoperative management. This study primarily aimed to summarize the current evidence on functional outcomes for Weber C patients managed operatively and nonoperatively. Evidence on secondary outcomes such as complications and radiographic outcomes were also reviewed. This systematic search was conducted according to PRISMA guidelines. A literature search was conducted using the EMBASE, Medline, and Central databases. A total of 26 studies were included in the final analysis. All papers studied the management of Weber C fractures using open reduction and internal fixation (ORIF). Three main functional outcome scores were identified: American Orthopedic Foot and Ankle Society score, Olerud-Molander Ankle Score, and Foot and Ankle Outcome Score. Only 1 study compared operative and conservative management, which showed similar outcomes for either option (median Olerud-Molander Ankle Score 95 [range 20 to 95] vs 100 [70 to 100], respectively). Complications associated with operative management included infection, wound dehiscence, implant failure, and malunion or nonunion. The mean rate of syndesmosis malreduction was 18.2%. This study showed that operative management, regardless of the method of ORIF used, as well as nonoperative management resulted in good functional outcomes, indicating that patient selection for either method is important. However, there is limited evidence on the complications and radiographic outcomes associated with nonoperative management. We recommend further studies to compare all ORIF methods with conservative management and examine the complications associated with nonoperative management.
