A randomised clinical trial of antiseptic nasal carrier cream and silver nitrate cautery in the treatment of recurrent anterior epistaxis

The addition of silver nitrate cautery to antiseptic nasal cream for patients with epistaxis: A systematic review and meta-analysis

OBJECTIVE

To compare the outcomes of the addition of silver nitrate cautery versus antiseptic cream alone in paediatric patients with recurrent epistaxis.

METHODS

A systematic review and meta-analysis were performed as per the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Guidelines and a search of electronic information was conducted to identify all Randomised Controlled Trials (RCTs) and non-randomised studies comparing the outcomes of the addition of silver nitrate cautery versus antiseptic cream alone in paediatric patients with recurrent epistaxis. Treatment success and persistence of bleeding were primary outcome measures. Secondary outcome measures included treatment side effects. Fixed effects modelling was used for the analysis.

RESULTS

Four studies enrolling 240 patients were identified. There was no significant difference between silver nitrate cautery group and antiseptic cream alone group in terms of complete resolution (Odds Ratio [OR] = 1.07, P = 0.81), the partial resolution (OR = 1.02, P = 0.96) and persistence of bleeding (OR = 0.91, P = 0.71). For secondary outcomes, antiseptic nasal cream was associated with few side effects such as rash in one case and several complaints of bad smell or taste.

CONCLUSIONS

The addition of silver nitrate cautery is not superior to the use of antiseptic cream alone in paediatric patients with recurrent epistaxis as it does not improve treatment success or persistence of bleeding.

Efficacy and Safety of Intranasal Medical Management in Pediatric Patients with Idiopathic Recurrent Epistaxis

Objective:

The goal of the study was to verify the efficacy and safety of topical medical treatment in idiopathic recurrent pediatric epistaxis patients by intranasal usage of both an antimicrobial and a moisturizing agent as a first-step management modality.

Method:

Sixty-seven out of 326 pediatric patients with idiopathic recurrent epistaxis selected on a chart review of follow-up were enrolled in the study. The study was designed as an analysis of two groups: one group included 35 individuals (52.2% of the total cohort) having a hyperemic nasal mucosa and the second group included 32 individuals (47.8% of the total cohort) having a hypervascular nasal mucosa on physical examination before treatment.

Results:

The study was performed with a total of 67 children (age range 3-17 years) including 36 males (53.7% of total cohort) and 31 females (46.3% of total cohort). The mean age was 9.78±4.09 years. There was not any statistically significant difference between the groups in terms of age, duration of follow-up and recurrence time of epistaxis (p>0.05). Recurrence of epistaxis was seen in 22.9% (8/35) of hyperemic nasal mucosa group and in 34.4% (11/32) of hypervascular nasal mucosa group (p>0.05).

Conclusion:

We advise the use of both an intranasal antimicrobial ointment and a mucosal moisturizing gel as an effective, noninvasive and easily applicable medical treatment option for pediatric patients with idiopathic recurrent epistaxis before more invasive methods of epistaxis control.

Comparison of topical treatment methods used in recurrent anterior epistaxis: a randomized clinical trial

Introduction

Recurrent epistaxis is a common medical problem faced by ENT specialists, emergency physicians, and pediatricians. The facts that many treatment modalities are being searched and no single treatment method is universally accepted yet support this information.

Objective

We aimed to compare the clinical efficacy of topical antiseptic ointment, topical decongestant ointment and chemical cauterization treatments, which are frequently used in recurrent anterior epistaxis, both singly and in combination.

Material-methods

Between August 2017 and February 2018, 137 patients who were diagnosed with recurrent anterior epistaxis were randomly divided into 5 groups. group I received topical antiseptic ointment, group II received topical decongestant ointment, group III received chemical cauterization, group IV received topical antiseptic ointment + chemical cauterization and group V received topical decongestant ointment + chemical cauterization treatment. All patients were phoned 2 weeks and 1 month after the treatment and questioned about the presence (failure) or absence (success) of at least 1 episode of epistaxis. Patients with comorbid diseases were excluded. Treatment success was statistically analysed.

Results

There was no significant difference (p > 0.05) between the groups in the success rate at 15th day after treatment. Group IV and group V had higher success rates at 30th day after treatment compared with group I and group II (p < 0.05). In group III 30th day treatment success was not different from the other 4 groups (p > 0.05).

Conclusion

Although the number of patients who improved with chemical cauterization (group III) was higher in our study, no significant difference was observed in single treatment modalities (group I‒III) at 14th day and 30th day after treatment. Although no statistically significant difference was observed between combined treatments (group IV—V) and single treatments (group I‒III) in the 2nd week after treatment, combined treatments were significantly more effective in the 1st month.

Randomized controlled trial comparing Nd:YAG laser photocoagulation and bipolar electrocautery in the management of epistaxis

The objective of this study is to evaluate the efficacy and degree of comfort of Nd:YAG laser photocoagulation compared to bipolar electrocautery in the management of epistaxis. Seventy-two consecutive patients with a history of epistaxis were randomly assigned to receive treatment in an outpatient setting consisting of either bipolar electrocautery (group 1) or Nd:YAG laser photocoagulation (group 2). The study was conducted in university-affiliated teaching hospital. Seventy-two consecutive patients who suffered from anterior epistaxis and presented to the Otolaryngology Department at the Eye, Ear, Nose and Throat Hospital, Fudan University, between June 2015 and August 2015. The following outcome measures were assessed: bleeding intensity, bleeding frequency 4 and 16 weeks after treatment (0 = no bleeding, 1 = reduced bleeding, 2 = the same, and 3 = worse), participant perception of discomfort during treatment (grade 0-10, where 10 is the worst pain), and therapy duration and complications. At 16 weeks, 91% of the laser patients versus 91% of the bipolar electrocautery patients had no reported bleeding. The outcome scores at 4 and 16 weeks after treatment showed no significant difference between the two groups (P = 0.5 and P = 0.98, respectively; P > 0.05). The median pain levels experienced during the office laser and bipolar electrocautery procedures were 3.0 and 4.0, respectively, and the median durations of the laser and electrocautery therapies were 3.0 and 4.0, respectively. Neither groups had complications. It can be concluded that Nd:YAG laser photocoagulation and bipolar electrocautery are both effective in the treatment of epistaxis. These two therapies are recommended. As a whole, these two therapies, performed in an office setting, are timely, efficacious, and well tolerated in the treatment of epistaxis.

Emergency Department care of childhood epistaxis

OBJECTIVE

The aim of this review is to determine an efficient and safe primary strategy care for paediatric epistaxis.

DATA SOURCES

We searched PubMed and Cochrane databases for studies referenced with key words 'epistaxis AND childhood'. This search yielded 32 research articles about primary care in childhood epistaxis (from 1989 to 2015). Bibliographic references found in these articles were also examined to identify pertinent literature. We compared our results to the specific management of adult epistaxis classically described in the literature.

RESULTS

Epistaxis is one of the most common reasons for referral of children to a hospital ENT outpatient department. The bleeding usually originates from the anterior septum, as opposed to adults. Crusting, digital trauma, foreign bodies and nasal colonisation with Staphylococcus aureus have been suggested as specific nosebleed factors in children. Rare aetiologies as juvenile nasopharyngeal angiofibroma appear later during adolescence. There are different modes of management of mild epistaxis, which begin with clearing out blood clots and bidigital compression. An intranasal topical local anaesthetic and decongestant can be used over 6 years of age. In case of active bleeding, chemical cauterisation is preferred to anterior packing and electric cauterisation but is only feasible if the bleeding site is clearly visible. In case of non-active bleeding in children, and in those with recurrent idiopathic epistaxis, antiseptic cream is easy to apply and can avoid 'acrobatic' cauterisation liable to cause further nasal cavity trauma.

CONCLUSIONS

Aetiologies and treatment vary with patient age and the existence or not of active bleeding at the time of the examination. Local treatments are usually easy to perform, but physicians have to ponder their indications depending on the possible complications in order to inform parents and to know paediatric epistaxis specificities.

Long-term result of out-patient neodymium-doped yttrium aluminium garnet laser photocoagulation surgery for patients with epistaxis

OBJECTIVE

To evaluate the long-term efficacy of out-patient neodymium-doped yttrium aluminium garnet laser photocoagulation surgery for patients with epistaxis.

METHODS

A retrospective clinical study was conducted. A total of 217 consecutive patients who presented with acute or recurrent epistaxis received neodymium-doped yttrium aluminium garnet laser photocoagulation treatment in an out-patient setting.

RESULTS

At three years, 94 per cent of acute epistaxis patients versus 88 per cent of recurrent epistaxis patients reported no bleeding. The outcome scores at 12 weeks and 3 years after treatment showed no significant differences between the 2 groups (p = 0.207 and p = 0.186). However, there was a significant difference in outcome scores at four weeks after treatment (p = 0.034). The median (and mean ± standard deviation) pain levels experienced during the laser operation (performed in an office setting) were 4.0 (3.75 ± 2.09) in the acute epistaxis group and 4.0 (3.83 ± 2.01) in the recurrent epistaxis group. Neither group had any complications.

CONCLUSION

Neodymium-doped yttrium aluminium garnet laser photocoagulation is desirable in the treatment of both acute and recurrent epistaxis, and has long-lasting efficacy.

Long-term efficacy of Nd:YAG laser photocoagulation vs. liquid paraffin plus antiseptic cream in the treatment of recurrent epistaxis

The objective of this study was to evaluate the long-term efficacy of Nd:YAG laser photocoagulation with that of liquid paraffin plus antiseptic cream in the management of recurrent epistaxis. Eighty consecutive patients who suffered from recurrent anterior epistaxis presented to the Otolaryngology Department at the Eye and ENT Hospital, Fudan University between February 2011 and June 2011. These patients with histories of recurrent epistaxis were randomly assigned to receive treatment in an outpatient setting consisting of either a combination of liquid paraffin plus antiseptic cream (Group 1) or Nd:YAG laser photocoagulation (Group 2).

MAIN OUTCOME MEASURES

the following outcome measures were assessed: bleeding intensity; bleeding frequency 2 years after treatment (0 = no bleeding, 1 = reduced bleeding, 2 = the same, 3 = worse), participant's perception of discomfort during the management (grade 0-10, where 10 is the worst pain), and complications. Finally, 70 patients remain in our study. At 2 years, 86 % of laser patients versus 31 % of control patients had no reported bleeding. The outcome score at 2 years after treatment showed a significant difference between the two groups (P = 0.000, P < 0.01). The median and mean ± SD pain levels experienced were 5.0 and 5.2 ± 2.2. Both groups had no complications. It can be further concluded that Nd:YAG laser photocoagulation is a preferable therapy in the treatment of recurrent epistaxis in long-term efficacy. The level of pain associated with the procedure was well tolerated. It is a simple, easy, safe and rapid therapy, which can be performed in an office setting.

A prospective randomised controlled trial of Nd:YAG laser photocoagulation versus liquid paraffin plus antiseptic cream in the treatment of recurrent epistaxis

OBJECTIVES

To evaluate the efficacy of Nd:YAG laser photocoagulation with that of liquid paraffin plus antiseptic cream in the management of recurrent epistaxis.

DESIGN

Prospective clinical study. Eighty consecutive patients with histories of recurrent epistaxis were randomly assigned to receive treatment in an outpatient setting consisting of either a combination of liquid paraffin plus antiseptic cream (group 1) or Nd:YAG laser photocoagulation (group 2).

SETTING

University-affiliated teaching hospital.

PARTICIPANTS

Eighty consecutive patients who suffered from recurrent anterior epistaxis presented to the Otolaryngology Department at the Eye and ENT Hospital, Fudan University between February 2011 and June 2011.

MAIN OUTCOME MEASURES

  The following outcome measures were assessed: bleeding intensity, bleeding frequency 4 and 12 weeks after treatment (0 = no bleeding, 1 = reduced bleeding, 2 = the same, 3 = worse), participant's perception of discomfort during the management (grade 0-10, where 10 is the worst pain) and complications.

RESULTS

At 12 weeks, 85% of laser patients versus 40% of control patients had no reported bleeding. The outcome score at 4 weeks after treatment showed no significant difference between the two groups (P = 0.130, P > 0.05); however, the outcome score at 12 weeks after treatment showed a significant difference between the two groups (P = 0.000, P < 0.01). The median and mean ± sd pain levels experienced were 5.0 and 5.2 ± 2.2. Both groups had no complications.

CONCLUSIONS

It can be concluded that Nd:YAG laser photocoagulation is a preferable therapy in the treatment of recurrent epistaxis, especially in terms of long-lasting efficacy. The level of pain associated with the procedure was tolerated. It is a simple, easy, safe and rapid therapy, which can be performed in an office setting.

Interventions for recurrent idiopathic epistaxis (nosebleeds) in children

BACKGROUND

Recurrent idiopathic epistaxis (nosebleeds) in children is repeated nasal bleeding in patients up to the age of 16 for which no specific cause has been identified. Although nosebleeds are very common in children, and most cases are self limiting or settle with simple measures (such as pinching the nose), more severe recurrent cases can require treatment from a healthcare professional. However, there is no consensus on the effectiveness of the different clinical interventions currently used in managing this condition.

OBJECTIVES

To assess the effects of different interventions for the management of recurrent idiopathic epistaxis in children.

SEARCH METHODS

We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the most recent search was 5 March 2012.

SELECTION CRITERIA

We identified all randomised controlled trials (RCTs) (with or without blinding) in which any surgical or medical intervention for the treatment of recurrent idiopathic epistaxis in children was evaluated in comparison with either no treatment, a placebo or another intervention, and in which the frequency and severity of episodes of nasal bleeding following treatment was stated or calculable. The two authors reviewed the full-text articles of all retrieved trials of possible relevance and applied the inclusion criteria independently.

DATA COLLECTION AND ANALYSIS

We graded trials for risk of bias using the Cochrane approach. One author performed data extraction in a standardised manner and this was rechecked by the other author. Where necessary we contacted investigators to obtain missing information. We did not undertake a meta-analysis because of the heterogeneity of the treatments, procedures and quality of the included trials. A narrative overview of the results is therefore presented.

MAIN RESULTS

Five studies (four RCTs and one quasi-randomised controlled trial) involving 468 participants satisfied the inclusion criteria. The identified RCTs compared 0.5% neomycin + 0.1% chlorhexidine (Naseptin®) cream with no treatment, Vaseline® petroleum jelly with no treatment, 75% with 95% silver nitrate nasal cautery, and silver nitrate cautery combined with Naseptin® against Naseptin® alone; the quasi-randomised controlled trial compared Naseptin® antiseptic cream with silver nitrate cautery. Overall results were inconclusive, with no statistically significant difference found between the compared treatments upon completion of the trials, however 75% silver nitrate was more effective than 95% silver nitrate at two weeks following application. The group treated with 75% silver nitrate had 88% complete resolution of epistaxis compared to 65% in the group treated with 95% silver nitrate (P = 0.01). No serious adverse effects were reported from any of the interventions, although children receiving silver nitrate cautery reported that it was a painful experience (despite the use of local anaesthetic). The pain scores were significantly less in those treated with 75% silver nitrate, the mean score being 1 compared to a mean score of 5 in those treated with 95% silver nitrate; this was statistically significant (P = 0.001).We carried out a 'Risk of bias' assessment of each study according to the Cochrane methodology and judged that two randomised controlled trials had a low risk of bias, two had an unclear risk of bias and the quasi-randomised controlled trial had a high risk of bias.

AUTHORS' CONCLUSIONS

The optimal management of children with recurrent idiopathic epistaxis is unknown, however if silver nitrate nasal cautery is undertaken 75% is preferable to 95% as it is more effective in the short term and causes less pain. High-quality randomised controlled trials comparing interventions either with placebo or no treatment, and with a follow-up period of at least a year, are needed to assess the relative merits of the various treatments currently in use.

Role of bacterial biofilms in idiopathic childhood epistaxis

The objective of the study is to conduct a prospective trial investigating the possible role of bacterial biofilms in the pathogenesis of severe idiopathic childhood epistaxis. This study included 84 cases of severe idiopathic epistaxis, aged below 16 years, who were prepared for cautery under general anesthesia. A nasal swab was taken for bacterial culture and a nasal mucosal specimen (≤ 3 mm(2)) was taken from the suspected site of bleeding just prior to cautery and sent for bacterial identification by pathogen specific fluorescence in situ hybridization (FISH) and also for detection of bacterial biofilms by scanning electron microscope (SEM). Nasal mucosal specimens from 20 children of the same age prepared for reduction of fracture nasal bones and have no nasal problems were taken as a control group. Bacterial culture was positive in 27.3 % of patients and the most common organism was Staphylococcus aureus (19 %). By SEM, biofilm formation was detected in only six patients (7.1 %). Evaluation of nasal specimens with FISH was positive for pathogenic bacteria in 37 % of cases; the most common organism was S. aureus (22.6 % of cases). In the control group, no biofilm was detected by SEM and no pathogenic bacteria were cultured or detected by FISH. The difference between the two groups was statistically significant. Bacterial biofilm does not seem to play a major role in the pathogenesis of idiopathic epistaxis in children (only positive in 7.1 % of cases by SEM) although a low-grade chronic inflammation is not infrequently present (37 % of cases detected by FISH). FISH is more sensitive than bacterial culture in detecting bacterial infections. S. aureus was the most common pathogen detected by both techniques.

Is local ointment or cauterization more effective in childhood recurrent epistaxis

OBJECTIVES

To compare the efficacy of nasal antiseptic ointment and silver nitrate cautery in the treatment of children with recurrent epistaxis.

METHODS

In this prospective and randomized study, a hundred children with recurrent epistaxis were assigned into two groups. In group 1, patients underwent silver nitrate cauterization, in group 2 patients were treated with nasal antiseptic ointment (oxytetracycline hydrochloride-polymyxin B sulfate); and both groups were followed for 3 months. All of the patients were investigated for allergy with skin prick test.

RESULTS

The ages of patients were similar in both groups (group 1: 9.2±2.7; group 2: 8.2±2.2; p=0.069). Thirty-eight percent of the patients in group 1 and 52% of the patients in group 2 had epistaxis in the three months follow-up. The difference between groups was not significant (p=0.159). Thirteen (26%) of the patients in group 1 and 12 (24%) of the patients in group 2 were found to have allergic symptoms and positive prick test. The rate of allergy was similar in both groups (p=0.817).

CONCLUSION

Nasal antiseptic ointment and silver nitrate cauterization were found to have similar outcomes in the treatment of recurrent epistaxis.

Effectiveness of a nasal saline gel in the treatment of recurrent anterior epistaxis in anticoagulated patients

We believe that the use of cauterization in patients with anterior epistaxis in the absence of acute bleeding should be discouraged because it does not address the underlying cause and because it may even worsen the condition by extending the degree of mucosal disruption. This is especially true in patients who are receiving anticoagulation therapy. Therefore, we conducted a study to determine if the use of a nasal saline gel as monotherapy would be an effective alternative to invasive measures in treating recurrent epistaxis in anticoagulated patients. Our study group consisted of 74 patients-43 men and 31 women (mean age: 64.4 yr)-who had been seen in our department over an 18-month period and whose bleeding had originated in the anterior portion of the nasal vault. Most patients had been experiencing epistaxis for at least 6 months. Patients were given the saline nasal gel and taught to gently apply it to the mucosa of the anterior nasal vault with a cotton-tipped applicator at the first sign of recurrent bleeding. Patients were then followed up periodically over the next 3 months. Among the 74 patients, 69 (93.2%) had experienced a cessation of their epistaxis at 3 months. The results of our study suggest that this simple, painless technique has considerable value as a treatment option in this cohort of patients.

The pathology of visible blood vessels on the nasal septum in children with epistaxis

OBJECTIVE

Epistaxis is common in children, but its cause remains unknown. About half the children who present with epistaxis have prominent vessels on the nasal septum. The aim of this study was to determine the pathological nature of the prominent septal vessels in children with recurrent epistaxis.

METHODS

4mm punch biopsies of the nasal septal mucosa were taken from 5 children undergoing nasal cautery under general anaesthesia.

RESULTS

Histology showed that the prominent vessels were thin-walled arterioles and capillaries with a surrounding inflammatory infiltrate. There was no evidence of venous varicosities or arterial microaneurysms.

CONCLUSION

We postulate a mechanism for septal neovascularisation due to chronic low-grade inflammation as a cause for recurrent epistaxis in children.

Prospective double blind randomized clinical trial comparing 75% versus 95% silver nitrate cauterization in the management of idiopathic childhood epistaxis

PRIMARY OUTCOME MEASURE

to evaluate which concentration of silver nitrate cauterization was more efficacious in the management of idiopathic childhood epistaxis.

SECONDARY OUTCOME MEASURES

to evaluate side effects and pain scores of the differing concentrations.

STUDY DESIGN

Prospective double blind randomized clinical trial.

PARTICIPANTS AND SETTING

All children 16 years of age or younger referred by the accident and emergency department or general practitioner, with recurrent idiopathic epistaxis, who met the inclusion criteria entered the trial. Patients were randomized to receive either the 75% or 95% silver nitrate cauterization. Patients were reviewed at two weeks and eight weeks post cauterization. Pain scores, side effects and success of each treatments were recorded at the follow up clinic.

RESULTS

101 patients completed the trial. 52 patients were randomized to receive the 95% concentration, and 49 patients were randomized to receive the 75% cauterization. In the 75% concentration group, 98% of patients had total resolution of their symptoms at the eight-week follow up. Mean pain scores in this group was 1 out of 10. In the 95% group, 90% had total resolution of their symptoms at the eight-week follow up. Mean pain scores in this group was 5 out of 10. There was a statistical difference in efficacy and pain scores (0.01 and 0.001).

CONCLUSION

We would recommend the use of 75% silver nitrate cauterization in the management of childhood epistaxis, it appears to be more efficacious, has fewer side effects and is better tolerated.

Frequency and management of epistaxis in schools

STUDY OBJECTIVES

To investigate the frequency and management of epistaxis in schools.

STUDY DESIGN

A postal survey of schools.

RESULTS

One hundred and fifty-seven questionnaires were posted out to 41 secondary schools (students aged 11-18 years) and to 116 primary schools (students aged four to 11 years). One hundred and twelve completed questionnaires were returned, 32 from secondary schools and 80 from primary schools. Most schools stated that they encountered a nose bleed once per month. The commonest method of treating a nose bleed was to pinch the top of the nose (an ineffective method), although pinching the bottom of the nose was almost as common. Only a minority of primary and secondary schools (37.5 and 25 per cent, respectively) had a policy for dealing with nose bleeds. Despite many respondents reportedly using an ineffective method, only two stated that they did not feel confident in dealing with nose bleeds.

CONCLUSION

Nose bleeds in school students are common, and management frequently deviates from recommended guidelines.

Bilateral simultaneous nasal septal cauterization in children with recurrent epistaxis

OBJECTIVE

To investigate the feasibility, effectiveness and complications of bilateral simultaneous silver nitrate cauterization for anterior nasal septal epistaxis in otherwise healthy children.

METHODS

Prospective study in a tertiary referral otorhinolaryngology department. Thirty-seven children with anterior epistaxis between the ages of 5-16 years were included in the study. The patients who had varicose vessels or network of small vessels in the Little's area had simultaneous bilateral silver nitrate cauterization.

RESULTS

Complete or near-complete epistaxis control was obtained in 76% of the patients after the first cauterization, and in 86% of the patients after the second cauterization in a mean follow-up period of 8 months. Partial success was obtained in five patients. The crusting in the cauterization area was healed late in six patients. Septal perforation, tattooing, or mucocutaneous/allergic reactions were not observed in any of the patients.

CONCLUSIONS

Bilateral silver nitrate cauterization is an effective, feasible, low-cost and preferable treatment method in childhood epistaxis when it is applied in an appropriate concentration and at an appropriate duration in a healthy mucosal environment.

A model of airflow in the nasal cavities: Implications for nasal air conditioning and epistaxis

BACKGROUND

A friction force is generated when moving air contacts the nasal walls, referred to as wall shear stress. This interaction facilitates heat and mass transfer between the mucosa and air, i.e., air-conditioning. The objective of this research was to study the distribution of wall shear stress within the nasal cavity to identify areas that contribute significantly to air-conditioning within the nasal cavity.

METHODS

Three-dimensional computational models of the nasal airways of five healthy subjects (three male and two female subjects) were constructed from nasal CT scans. Numerical simulations of nasal airflow were conducted using the commercial computational fluid dynamics code Fluent 6 (Ansys, Inc., Canonsburg, PA). Wall shear stress was derived from the numerical simulation. Air-conditioning was simulated to confirm the relationship with wall shear stress.

RESULTS

Nasal airflow simulations predicted high wall shear stress along the anterior aspect of the inferior turbinate, the anteroinferior aspect of the middle turbinate, and within Little's area.

CONCLUSION

The airflow simulations indicate that the inferior and middle turbinates and Little's area on the anterior nasal septum contribute significantly to nasal air-conditioning. The concentration of wall shear stress within Little's area indicates a desiccating and potentially traumatic effect of inhaled air that may explain the predilection for spontaneous epistaxis at this site.

A double-blind randomized controlled trial of management of recurrent nosebleeds in children

Background: To establish whether a treatment regimen of silver nitrate cautery and 4 weeks of antiseptic nasal cream is superior to antiseptic cream treatment alone in the management of pediatric epistaxis.

Study Design: Double-blind randomized controlled trial.

Subjects and Methods: Children with epistaxis and visible anterior septal vessels were invited to participate. Patients were randomized to receive treatment or control. Treatment patients received silver nitrate cautery, followed by antiseptic cream for 4 weeks. Control patients received sham cautery followed by antiseptic cream for 4 weeks.

Results: A total of 109 patients were randomized and results were available for 93 (85%). Of those receiving cautery, 21 (45.7%) of 46 had no bleeding in the 4 weeks before follow-up. Of those receiving only antiseptic cream 14 (29.8%) of 47 had no bleeding. (χ2 = 2.49; P = 0.114). More children in the active treatment group had an improvement in their symptoms compared with controls (42 of 46; 91.3%) in the treatment group vs 33 of 47 (70.2%) controls (χ2 = 6.626; P = 0.01; relative risk reduction = 71 percent, number needed to treat = 4.7).

Conclusion: When using subjective improvement in symptoms as the outcome measure, silver nitrate cautery with antiseptic cream twice daily for 4 weeks appears to give a small but statistically significant benefit when compared to antiseptic cream alone.

Topical management of anterior epistaxis: a national survey

Introduction:

The use of nasal creams and ointments in the conservative management of anterior epistaxis is well documented and supported. This study set out to obtain a national opinion, in order to establish current practice.

Design:

A survey of all Scotland-based otolaryngology clinicians was conducted. Participants were asked which topical treatment they used in their practice, how often and for how long they advocated its use, and how they advised their patients to apply it.

Results:

The overall response rate was 91 per cent. We discuss and compare the varying responses for the questions posed, and discuss the possible reasons for these in greater detail.

Conclusions:

This study demonstrates a high degree of variation in this practice, arising from a lack of concrete evidence and influenced by anecdotal experience and personal preferences. Definitive comparative studies are required if a ‘gold standard’ topical approach for the management of anterior epistaxis is to emerge.

Childhood epistaxis and nasal colonization with Staphylococcus aureus

OBJECTIVE

Epistaxis is very common in children but its cause remains unknown. We postulate that nasal colonization with Staphylococcus aureus leads to inflammation, crusting, and ultimately new vessel formation.

STUDY DESIGN

A prospective case-control study.

SUBJECTS AND METHODS

Sixty-seven children were recruited, 42 with epistaxis (22 had crusting in the nasal vestibule; 20 did not) and 25 control subjects. A microbiology swab was taken from the anterior nasal cavity of each child.

RESULTS

All groups were equally likely to have a positive culture. S aureus was more common in the epistaxis group (P = 0.008) compared with the control group. There was no difference in the prevalence of S aureus between crust and noncrust groups. Epistaxis patients were much less likely to have isolates of respiratory pathogens or a skin commensal.

CONCLUSION

Children with epistaxis are more likely to have nasal colonization with S aureus than controls. Our data would support the hypothesis that S aureus replaces existing nasal flora and causes inflammation and new vessel formation.

Long-term effectiveness of antiseptic cream for recurrent epistaxis in childhood: five-year follow up of a randomised, controlled trial

Objectives:

To determine the long-term outcome for children treated for recurrent epistaxis, and to compare the efficacy of antiseptic cream treatment and nasal cautery.

Study design and participants:

Retrospective analytical cohort study of 88 children treated for recurrent epistaxis in 2001.

Methods:

Five-year data on chlorhexidine–neomycin cream usage, nasal cautery, current epistaxis frequency and emergency room attendance was collected by telephone interview and case record review.

Results:

During their first clinic visit, 51 per cent of the children had been treated with cautery and cream and 35 per cent with cream alone; 14 per cent had received no treatment. Five years later, 65 per cent of these children were still having ongoing epistaxis. Those who had undergone cautery and received cream had the highest ongoing bleeding rate (77 per cent).

Conclusion:

The majority of children treated at our clinic for recurrent epistaxis had ongoing bleeding five years later. Despite the proven short-term efficacy of chlorhexidine–neomycin cream, few patients receive further courses of cream or are referred back to the clinic.

Bilateral epistaxis in children: efficacy of bilateral septal cauterization with silver nitrate

OBJECTIVE

To evaluate the rate of control of epistaxis in patients with bilateral complaints using silver nitrate and to assess short-term complications from this therapy.

STUDY DESIGN AND SETTING

Retrospective chart review with prospective incident case identification in a tertiary referral pediatric otolaryngology practice.

SUBJECTS AND INTERVENTIONS

Forty-six consecutive patients presenting to a single pediatric otolaryngologist with complaints of bilateral epistaxis received bilateral silver nitrate cauterization to the anterior septum and were seen in follow-up 2 months later to assess for control of epistaxis and complications from this therapy.

RESULTS

Ninety-three percent (43/46) of patients followed-up at 2 months after therapy. About 93% (40/43) had total or near-total resolution of their epistaxis. Five percent (2/43) of patients returned to the clinic after initial successful control for a second cauterization during the period of study. No significant complications of infection, perforation, long-term crusting, tattooing or mucocutaneous or allergic reactions were identified.

CONCLUSIONS

Bilateral epistaxis can be treated at a single visit with bilateral silver nitrate therapy in children. This treatment is highly effective, well-tolerated, and appears to have a low rate of complications.

Epistaxis

Epistaxis is a frequent complaint, and may often cause great anxiety in patients and clinicians. Epistaxis results from the interaction of factors that damage the nasal mucosal lining, affect the vessel walls, or alter the coagulability of the blood, and which may be categorized into environmental, local, systemic and medication related. The knowledge of the first aid treatment of epistaxis is very poor, amongst not only the public, but also health professionals. Immediate emergency department management of epistaxis depends on prioritized assessment and treatment, including resuscitation if necessary, together with the application of relatively simple otolaryngological techniques. There is little high quality evidence regarding routine, alternative or adjunctive treatments.

A prospective, single-blind, randomized controlled trial of petroleum jelly/Vaseline for recurrent paediatric epistaxis

The aim of the study was to determine if petroleum jelly was an effective treatment for paediatric epistaxis. A single-blind, prospective, randomized controlled trial was undertaken in an otolaryngology outpatient clinic of a paediatric hospital from March 2001 to March 2002. A total of 105 children referred with recurrent epistaxis were randomized into the study, 52 into the treatment arm and 53 into the control arm. Children in the treatment arm applied Vaseline twice a day bilaterally for 4 weeks and were monitored for any bleeds for the next 4 weeks. Children in the control arm were simply given an 8-week appointment and the number of bleeds were monitored for the 4 weeks prior to their appointment. The outcome measure was the proportion of children in each group without nosebleeds in the preceding 4 weeks. Both groups were equally distributed in age, duration of symptoms and duration of each bleed. Fourteen of 51 (27.5%) patients of the treatment arm and 18 of 53 (34%) of the control arm did not bleed in the 4 weeks before review (chi-square test, P = 0.472). It can be concluded that Vaseline alone confers no benefit over simple observation in recurrent childhood epistaxis.

Interventions for recurrent idiopathic epistaxis (nosebleeds) in children

BACKGROUND

Recurrent idiopathic epistaxis (nosebleeds) in children is repeated nasal bleeding in patients up to the age of 16 for which no specific cause has been identified. Although nosebleeds are very common in children, and most cases are self-limiting or settle with simple measures (such as pinching the nose), more severe recurrent cases can require treatment from a healthcare professional. However, there is no consensus on the effectiveness of the different clinical interventions currently used in managing this condition.

OBJECTIVES

To assess the effects of different interventions for the management of recurrent idiopathic epistaxis in children.

SEARCH STRATEGY

We searched the Cochrane ENT Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library Issue 3, 2003), MEDLINE (January 1966 to August 2003), EMBASE (January 1980 to August 2003), CINAHL (January 1982 to August 2003), and reference lists of relevant articles.

SELECTION CRITERIA

We identified all randomised controlled trials (with or without blinding) in which any surgical or medical intervention for the treatment of recurrent idiopathic epistaxis in children was evaluated in comparison with either no treatment, a placebo, or another intervention, and in which the frequency and severity of episodes of nasal bleeding following treatment was stated or calculable. The full text articles of all the retrieved trials of possible relevance were reviewed by the two reviewers and the inclusion criteria applied independently.

DATA COLLECTION AND ANALYSIS

Trials were graded for methodological quality using the Cochrane approach. Data extraction was performed in a standardised manner by one reviewer and rechecked by the other, and where necessary investigators were contacted to obtain missing information. A meta-analysis was not undertaken because of the heterogeneity of the treatments, procedures and quality of the included trials. A narrative overview of the results is therefore presented.

MAIN RESULTS

Three studies - two randomised controlled trials (RCTs) and one controlled clinical trial (CCT) - involving 256 participants satisfied the inclusion criteria. One RCT compared Naseptin antiseptic cream with no treatment, the second RCT compared Vaseline(R) petroleum jelly with no treatment, and the CCT compared Naseptin antiseptic cream with silver nitrate cautery. Overall, results were inconclusive, with no statistically significant difference found between the compared treatments. No serious adverse effects were reported from any of the interventions, although children receiving silver nitrate cautery reported that it was a painful experience (despite the use of local anaesthetic).

REVIEWER'S CONCLUSIONS

The optimal management of children with recurrent idiopathic epistaxis is unknown. High quality randomised controlled trials comparing interventions either with placebo or no treatment, and with a follow-up period of at least a year, are needed to assess the relative merits of the various treatments currently in use.

A prospective, single-blind, randomized controlled trial of antiseptic cream for recurrent epistaxis in childhood

Epistaxis is common in children. Trials show antiseptic cream is as effective as cautery, but it is not known whether either is better than no treatment. We wished to know the efficacy of cream in children with recurrent epistaxis. The design was a single-blind, prospective, randomized controlled trial set in the Otolaryngology clinic in a children's hospital. The participants were 103 children referred by their general practitioner for recurrent epistaxis. Excluded were those with suspected tumours, bleeding disorders or allergies to constituents of the cream. Referral letters were randomized to treatment and no treatment groups. Treatment was antiseptic cream to the nose twice daily for 4 weeks, which was prescribed by the general practitioner before clinic attendance. All children were given an appointment for 8 weeks after randomization. The main outcome measures were the proportion of children in each group with no epistaxis in the 4 weeks preceding clinic review. Complete data were available for 88 (85%) of the children. Of the treatment group, 26/47 (55%) had no epistaxis in the 4 weeks before the clinic appointment. Of the controls, 12/41 (29%) had no epistaxis over the 4 weeks. This is a relative risk reduction of 47% for persistent bleeding (95% CI 9-69%) and an absolute risk reduction of 26% (95% CI 12-40%), giving a number needed to treat of 3.8 (95% CI 2.5-8.5). We conclude that antiseptic cream is an effective treatment for recurrent epistaxis in children.
