Halo external fixator
Due to a lack of clear evidence there are many inconsistencies with pin site management and prevention of pin site infections, however the goal of management should be to prevent the colonisation of the pins and wires and therefore prevent infection (Walker 2012) with regular. A popular method of pin site care involves using normal saline or an antimicrobial agent and gauze to clean the pin site areas. This can be done twice a day, daily or even weekly depending on protocols (lee. Pin site care protocols are dependent on a variety of factors and are often different depending on the preference of the surgeon, nurse, habit, consensus and basic principles of wound care (davies. It must be remembered though that complete healing of the site is not the goal of pin site care, so some wound care techniques can be inappropriate (davies. Nurses must also ensure that patients are educated on the signs and symptoms of infection so this complication can be monitored, and also on any restrictions which may be enforced on them due to both their injury or surgery and the use of the external. It is also important to elevate the limb post-operatively and whenever the patient is not mobilising.
When severe infection occurs, the stability of the fixation can become impaired. This can result in the removal of the pin or wire, but even after its removal the infection can still linger (davies. Thankfully, superficial infections are more common in patients with external fixation devices than more severe types of infection. However, even a superficial infection causes the individual pain and can interfere with their recovery and rehabilitation (davies. The early recognition of potentially infected pin sites is essential in managing the complication efficiently. This involves documentation and monitoring of all pin sites through regular pin site care. Nurses and patients should take particular note of the presence and extent of erythema, tenderness, swelling and discharge (Walker 2012). Pin Site care, there is little evidence to support one type of pin care protocol over another, and this can be attributed to the fact that there is no validated grading system or definition for pin site infections (lee. Some protocols involve the use of antiseptic solutions, others use pressure dressings to restrict the movement between the skin and the pin (davies. The use of pressure dressings can be especially beneficial to those pins sites that are near joints, which tend to be more prone to infection due to increased amounts of movement (davies.
healing of the site is prevented by the presence of the pin, therefore wound care revolves around keeping those sites clean and free from infection (davies. ( (Read Ausmeds, wound Care and wound healing guide for more information. there are many individual factors that can also increase the risk of the individual developing pin site infection. These include the patients age, any pre-existing medical conditions, the cause of the need for the external fixation device, and the duration the device is needed. A study also found that weather can have an impact on pin site infections, with the rate of infections found to be higher during the warmer seasons (kao. The risk of developing a pin site infection increases with the length of time the fixation device is in place. Pin site infections will usually begin as cellulitis, and treatment of the infection will depend on the type of infection. In most cases, a minor superficial infection can be treated with increased pin site care in conjunction with oral antibiotic therapy (Walker 2012). Most infections respond to oral antibiotics as generally they are from. Staphylococcus Aureus infection, but sometimes they do extend into deeper tissues and bone causing osteomyelitis, septic arthritis and in some cases septicaemia (Walker 2012).

2015; vaidya. (DVTs and PEs are also potential complications following orthopaedic surgery and are therefore potential complications for those with external fixation devices. However, there is buikhuid limited evidence that the clots can be caused by the use of the devices themselves, and rather are more likely a result what's of the surgery (Roberts et al, 2015). Pins within the external fixator can also loosen. This can then create an unstable fixator, which results in an unsuitable environment for bone healing, increased movement in the limb and pin site irritation, which is often a precursor for pin site infection. Pins can loosen for a variety of reasons, one of which being when the pin is uncoated it can lead to a fibrous tissue formation where the pin meets the bone (Ferreira marais 2012). Pin Site Infection, one of the most common risks involved when external fixation devices are used is infection. A pin site cannot heal whilst the pin and external fixator is in situ, therefore it is essential that pin site care is attended regularly to decrease the risk of potential infection.

10, 14 For pin-site management, chlorhexidine 2 mg/mL may be the most effective solution to promote comfort and reduce infection and the need for medication. Promising dressings in reducing pin-site infections include combined 5 chlorhexidine/1 silver sulphadiazine or Xeroform dressings. 12, 13 Until further studies support cost/benefit analysis for supplementing half-strength H2O2 with Xeroform dressings, clinicians are advised to wait before adding this extra cost to care. Clearly, patients and their families should be taught pin-site care, including signs and symptoms of infection. 4 Manufacturers recommendations (level M) provide additional considerations to guide practice in the absence of stronger conclusive evidence. One major manufacturers online guidelines for external limb fixators recommends that patients cleanse the pin site, from the first day that fixators are applied until the day they are removed, with sterile gauze impregnated with sterile water (or other solution) ordered by the surgeon. 20 Patients are instructed to wash their hands, and using a fresh swab for each pin, remove any crust and then dry with a fresh swab. Additionally, patients are instructed to cleanse the length of each pin and wrap with loose gauze for about 5 days until pin sites are dry. No showering is advised until after 10 days.
13, no significant difference in infection rates was documented between plain versus silver sulfadiazine dressings in another study. 17, frequency of Pin-Site management daily versus weekly cleansing of healthy pin sites or dressing change protocols appeared to make no difference for maintenance care. 10, 14 Showering In an earlier prospective study, gordon et al 18 followed up 27 children after teaching families a paper simple pin-care system with no cleansing of tibial pins other than daily showers. Reporting only 4 pin-site infections, these investigators recommended simple showering with no additional pin-site hygiene. In a more recent study, 16 researchers found no difference in infection rates between showering and gentle cleansing of tibial pins with soft toothbrushes versus showering and cleansing crusts with sterile gauze impregnated with 10 polyvinyl-pyrrolidone iodine. Previous Section Next Section Recommendations for Practice collective studies on solutions, dressings, frequency of pin care, and showering demonstrated level b evidence ( Table 2 ).
In the 1 systematic review 15 of 6 randomized controlled trials comparing different pin-site protocols in adults and children, researchers concluded that evidence was insufficient to recommend a specific technique to minimize infection and prevent kangen complications. Therefore, the main recommendation was to minimize the risk of cross-infection at pin sites. View this table: Table 2 American Association of Critical-Care nurses evidence-leveling systema however, evidence from a clinical practice guideline on skeletal pin-site care from the national Association of Orthopaedic Nurses (level D) and manufacturers recommendations (level M) provide additional considerations for practice in the absence. According to the clinical practice guideline, pin-site care should be done daily or weekly after the first 48 to 72 hours. 4 weekly pin-site care, which results in less cost and potentially better adherence by patients after discharge, is supported for (uninfected) pin sites.

View this table: Table 1, matrix of studies, solutions for Pin-Site care. Studies demonstrated mixed approaches to pin-site care using various products: chlorhexidine, hydrogen peroxide (H2O2 povidone-iodine, 1 silver sulphadiazine, and 5 chlorhexidine/paraffin. These heterogeneous comparisons and somewhat different samples make conclusions difficult. Fewer swiss infections were reported for povidone-iodine (vs paraffin 8 as well as chlorhexidine (vs normal saline which also resulted in less pain/antibiotic use. 5, although results of the latter study 5 indicated that chlorhexidine was more beneficial than normal saline in preventing. Staphylococcus aureus infections, comparisons with half-strength H2O2 were not examined. No differences in infection rates were found between 14 or between chlorhexidine and half-strength H2O2 iodine and normal saline. 11, dressings and Solutions, no studies compared dressing versus no dressing. Fewer infections were reported with combined 1 silver sulphadiazine/5 chlorhexidine dressings compared with 5 chlorhexidine dressings, 12 as well as H2O2/Xerofoam gauze dressings (Cardinal health, dublin, Ohio).

Clinicians may question if this treatment is aggressive enough to prevent infection. Pin sites located in significant soft-tissue areas have a higher risk of infection. 4, a skin infection surrounding pins can produce complications such as increased pain, delayed healing or fracture misalignment, osteomyelitis, or a systemic infection resulting in prolonged stay or readmission, and increased health care costs. 5, since this type of infection occurs in up to 20 of patients with external fixation devices, 6 it is imperative that nurses take appropriate preventive measures, prompting the following goji pico question: In patients with external fixators, what solution and cleansing frequency of pin sites. Method, a search, limited to articles from 2003 to 2011, was conducted in cinahl and medline using the following search terms: external fixator pin sites, pin sites, and pin site infections. Previous Section, next Section. Results, ten studies were retrieved: 2 prospective observational studies, 7 randomized controlled trials, and 1 systematic review. One additional study 7 was not included because pin-site comparison groups underwent different surgical techniques. Table 1 summarizes findings related to solutions, frequency of cleansing, dressings, and showering.
External fixators include pins and wires placed by surgeons to stabilize fractures such as those involving the tibia. In critical care, external fixators are more commonly used to stabilize cervical spine fractures. Because halo fixators secure cervical alignment, these devices allow early mobilization and shortened stays. However, halo-fixator complications include cranial pin loosening, localized infection, and superficial pressure sores. 1, 2, loosening of cranial pins for halo fixators with signs of local infection, fever, headaches, or seizures deserves rapid notification of the surgeon and neuroimaging. 3, likewise, any tracking (open area with skin pulled away from pins) or clicking noises necessitate prompt assessment by the surgeon for potential loosening of pins. Although daily assessment of pin sites to monitor for complications is not debated, reuma the approach to pin-site care to prevent infection is less clear-cut. A common method of site care involves using normal saline to clean around each pin.

External fixation devices are used to help immobilise a particular part of the body following a fracture or with certain orthopaedic problems to allow bone healing. They can allow the fixation and manipulation of multiple bone segments which would otherwise be very difficult. They involve the use of pins, wires and braces and are used when other options of immobilisation (such as plaster casts) would be ineffective (Singh 2016; Walker 2012). These devices can be used in limb length discrepancy surgeries, nerve and tendon repairs, and polytrauma patients with fractures, to name a few incidences. External fixation devices include circular fixators such as halo thoracic braces, Ilizarov fixators, and unilateral fixators (different from circular fixators as they are only positioned on one side of the limb) (Singh 2016). Risks of External Fixation devices, there are many risks associated with the use of external fixation devices which include those as a result of the device itself, as well as the initial injury that requires fixation. Pin site complications rates range from 7 100, with the majority of complications being infection. This broad range of numbers is problematic and due to the lack of a universal classification bleken for pin site infections (Walker 2012). The risks of external fixation devices include: (Roberts.
