Heel skin microclimate control: Secondary analysis of a self-controlled randomized clinical trial.

OBJECTIVE: this study was undertaken to evaluate the efficacy of multilayer polyurethane foam with silicone (MPF) compared to transparent polyurethane film (TPF) dressings in the control of heel skin microclimate (temperature and moisture) of hospitalized patients undergoing elective surgeries. METHOD: the study took of a secondary analysis of a randomized self-controlled trial, involving patients undergoing elective surgical procedure of cardiac and gastrointestinal specialties in a university hospital in southern Brazil, from March 2019 to February 2020. Patients served as their own control, with their heels randomly allocated to either TPF (control) or MPF (intervention). Skin temperature was measured using a digital infrared thermometer; and moisture determined through capacitance, at the beginning and end of surgery. The study was registered in the Brazilian Registry of Clinical Trials: RBR-5GKNG5. RESULTS: significant difference in the microclimate variables were observed when the groups (intervention and control) and the timepoint of measurement (beginning and end of surgery) were compared. When assessing temperature, an increase (+3.3 °C) was observed with TPF and a decrease (-7.4 °C) was recorded with MPF. Regarding skin moisture, an increase in moisture (+14.6 AU) was recorded with TPF and a slight decrease (-0.3 AU) with MPF. CONCLUSIONS: The findings of this study suggest that MPF is more effective than TPF in controlling skin microclimate (temperature and moisture) in heels skin of hospitalized patients undergoing elective surgeries. However, this control should be better investigated in other studies.

Comparison of Two Bandage Splint Constructs in an Ex Vivo Equine Metacarpal Fracture Model.

OBJECTIVES: The aim of this study was to compare the deflection distance, deflection angle and pre-loading sub-bandage pressure of a transverse, mid-metacarpal fracture in an equine cadaver limb when loaded in bending while stabilized with either a Robert Jones Bandage (RJB) or a single-stack bandage (SS), each containing two orthogonal splints. STUDY DESIGN: In an ex vivo experimental study, forelimb pairs from eight horses were collected, and one forelimb from each pair was assigned to either the SS or RJB groups. A transverse osteotomy was performed at the midpoint of the metacarpus. After bandaging, the limbs were loaded in bending. Pre-loading sub-bandage pressure, pre- and post-loading radiographs and post-loading deflection distance measurements were taken. Dorsopalmar radiographs were used to measure the loaded deflection angle. RESULTS: There was no significant difference between RJB and SS constructs in change in deflection angle (10.7 ± 3.0 degrees vs. 9.8 ± 2.6 degrees; p = 0.5) or deflection distance (13.1 ± 2.6 cm vs. 11.4 ± 3.1 cm; p = 0.2). Sub-bandage pressures were significantly greater for the SS than the RJB both dorsally and laterally. CONCLUSION: The SS splint construct resists bending forces similarly to the RJB splint construct in an ex vivo transverse, metacarpal fracture model. The SS splint construct may be a useful alternative to the RJB splint construct in field situations for metacarpal fracture stabilization.

Modified Robert Jones Bandage in reducing blood loss in total knee arthroplasty: A meta-analysis of randomized controlled trials.

BACKGROUND: The purpose of this meta-analysis was to assess the effects of Modified Robert Jones Bandage (MRJB) in primary total knee arthroplasty (TKA). METHODS: PubMed, EMBASE, the Cochrane Library, Web of Science, and Google Scholar were systematically searched for randomized controlled trials (RCTs). All RCTs were compared to receive either MRJB (study group) or conventional wound dressing (control group) in TKA. Statistical analysis was assessed using RevMan 5.3 software. RESULTS: A total of 5 RCTs involving 362 patients were included in the meta-analysis. No significant difference between the 2 groups was found in terms of total blood loss (Mean difference [MD], -25.41; 95% confidence interval [CI], -90.52 to 39.70; P = .44), intra-operative blood loss (MD, -13.77; 95% CI, -31.84 to 4.29; P = .14), drain blood loss (MD, 0.83; 95% CI, -30.07 to 31.72; P = .96), and transfusion rate (risk ratio, 0.95; 95% CI, 0.55-1.64; P = .86); There was also no significant difference in terms of range of motion (MD, -0.93; 95% CI, -3.64 to 1.79; P = .50), visual analog scale pain sores (MD, -0.02; 95% CI, -0.34 to 0.30; P = .90), and operative time (MD, -3.12; 95% CI, -13.42 to 7.18; P = .55), without increasing the risk of wound-related complications (risk ratio, 0.75; 95% CI, 0.27-2.08; P = .58) in both groups. No deep venous thrombosis occurred in all studies. CONCLUSIONS: The current meta-analysis of the available evidence indicates patients with MRJB had not required the additional advantage compared to the conventional wound dressing for TKA. However, more high-quality studies are needed to confirm the above conclusions. LEVEL OF EVIDENCE: Level I, therapeutic study.

Protective Dressings, Injury, and Device Failure in Preterm Infants Receiving Nasal Continuous Positive Airway Pressure: A Randomized Controlled Trial.

OBJECTIVE: To investigate the protective effect of a hydrocolloid nasal dressing on the incidence and severity of nasal injury and continuous positive airway pressure (CPAP) failure in preterm infants receiving nasal CPAP (N-CPAP). METHODS: A randomized controlled trial was conducted over 4 months in 2019 at level 3 neonatal ICUs in two hospitals affiliated with Isfahan University of Medical Sciences, Iran. Eighty eligible infants were born at 32 weeks of gestation or younger and/or with a birth weight of 1,500 g or less and had received between 4 and 72 hours of CPAP. Infants were randomly assigned to two groups; the intervention group used a protective dressing, and the control group received routine care. Data collection tools included a demographic questionnaire and nasal injury assessment score chart. MAIN OUTCOME MEASURES: The incidence and severity of nasal injury in preterm infants undergoing N-CPAP. RESULTS: Infants in the intervention group had a significantly lower incidence and severity of nasal injury compared with the control group: 15 of 40 (37.5%) versus 37 of 40 (92.5%; P < .001). Overall, the injuries identified in this study were mostly mild and moderate, with only three severe injuries in the intervention group and five in the control group. No significant differences were detected in CPAP failure (P > .05). CONCLUSIONS: The studied nasal barrier dressing is a safe and convenient solution to reduce nasal injury in preterm infants receiving N-CPAP.

Surgical Wound Complications after Colorectal Surgery with Single-Use Negative-Pressure Wound Therapy Versus Surgical Dressing over Closed Incisions: A Randomized Controlled Trial.

BACKGROUND: Global studies indicate that surgical site infections (SSIs) are a major healthcare challenge within hospitals and can have a profound impact on patient quality of life and healthcare costs. Closed-incision negative-pressure therapy (ciNPT) has been reported to provide positive clinical benefits for patients with various incisions, including those following colorectal surgeries. METHODS: Investigators performed a prospective, randomized, multicenter trial to evaluate complications of surgical incisions in patients who received a ciNPT dressing versus a conventional surgical dressing (control) over their closed incision following colorectal surgery. The incidence of SSI was determined at 7, 15, and 30 days postsurgery. RESULTS: A total of 148 patients participated in the study. Results showed that the SSI rate on day 7 was lower in the ciNPT group versus the control group (10/75 [13.3%] vs 17/73 [23.3%]), but this difference was not statistically significant. On day 15, the SSI rate was 12/75 (16.0%) in the ciNPT group versus 21/73 (28.8%) in the control group; however, this difference was only marginally statistically significant (P = .0621). At 1 month, the SSI rate remained lower in the ciNPT group (13/75 [17.3%] vs 21/73 [28.8%], P = .0983) compared with the control group. CONCLUSIONS: Future studies with larger population sizes are necessary to determine the impact of ciNPT on patients' incisions after colorectal surgery.

Preparation and evaluation of an innovative antibacterial bi-layered composite dressing for skin wound healing.

AIM OF THE STUDY: The aim of the current study was to develop collagen-based bi-layered composite dressings with antibacterial property and evaluate the efficiency for wound healing. MATERIALS AND METHODS: A bi-layered composite wound dressing was fabricated using two marine biomacromolecules (collagen and chitosan or carboxymethyl chitosan). Non-crosslinked and N-Ethyl-N'-(3-dimethylaminopropyl) carbodiimide/N-Hydroxy succinimide (EDC/NHS) cross-linked collagen sponges fabricated by vacuum freeze-drying technology was used as the inner layer. The medical spun-laced nonwoven coated with chitosan and carboxymethyl chitosan was used as the outer layer. The antibacterial activities against E. coli and S. aureus were evaluated by the inhibition zone assay. Deep second-degree scald model was performed to evaluate the efficiency of bi-layered composite dressings for wound healing. RESULTS: In view of comprehensive evaluation of appearance and in vitro antibacterial activity, medical spun-laced nonwoven coated with 3% of chitosan solution was chosen to be used as the optimized preparation conditions to produce the outer layer of composite dressing, which acted as a barrier against microorganisms and provided mechanical support. Furthermore, the results of wound closure and histopathological analysis indicated that EDC/NHS cross-linked collagen-based bi-layered composite dressing was superior to non-crosslinked and commercial products, which stimulated the wound healing process and accomplished deep second-degree scalded skin healing within a time span of 28 days. CONCLUSION: The EDC/NHS cross-linked collagen-based bi-layered composite dressing had immense potential to be applied for an ideal wound dressing for more efficient and faster wound healing. Therefore, the findings provided the essential theoretical basis for great potential of collagen-based composite dressing used in wound healing applications.

The Use of Prophylactic Foam Dressings for Prevention of Hospital-Acquired Pressure Injuries: A Systematic Review.

PURPOSE: The purpose of this systematic review was to identify and evaluate the use of prophylactic foam dressings for prevention of hospital-acquired pressure injuries (HAPIs). METHODS: A systematic review was conducted in accordance with the Preferred Reporting Items of Systematic Reviews and Meta-analysis Statement (PRISMA). SEARCH STRATEGY: Four researchers independently conducted searches in Health Source, Cochrane of Systematic Reviews, CINAHL, and PubMed. Search terms included: "pressure* OR skin breakdown AND sacrum*"; "ICU patient* OR critical care patient*"; and "foam dressing OR prophylactic* or prevent*." FINDINGS: The search identified 380 articles; 14 met eligibility criteria. The methodological quality of the included studies was variable. Findings from all studies included in our review support a decrease in HAPI incidence with use of sacral foam dressings. IMPLICATIONS: Findings from this review suggest that prophylactic foam dressings decrease sacral HAPI occurrences in critical care patients. While additional research is needed, current best evidence supports use of prophylactic foam sacral dressings for patients at risk for HAPI.

Therapeutic effect of continuous diffusion of oxygen therapy combined with traditional moist wound dressing therapy in the treatment of diabetic foot ulcers.

AIMS: To investigate the therapeutic effect of continuous diffusion of oxygen (CDO) combined with traditional moist wound dressing (MWD) on the diabetic foot ulcers (DFUs) inpatients. METHODS: The inpatients from May 2016 to April 2018 were enrolled and randomly divided into MWD, CDO and combination treatment groups (n = 40 each group). The moist dressing was used in the MWD group while a micro-oxygen supply device was used in the CDO group. The combination treatment group was given both MWD and CDO. All patients were treated for 8 weeks. The wound healing, amputation rate, and inflammatory control were evaluated. RESULTS: Compared with MWD and CDO groups, the combination group showed a higher wound healing rate (P < 0.05), lower white blood cell count (P < 0.05) and lower high-sensitivity C-reactive protein level (P < 0.05). During 1-year follow-up, the amputation rate was 0% in combination group, which was significantly lower than that in other two groups (P < 0.05). CONCLUSIONS: The combination of MWD and CDO was effective in promoting healing and preventing infection of DFUs, which holds a potential to be a new strategy for the treatment of this critical clinical condition.

Cost-effectiveness analysis of negative pressure wound therapy dressings after open inguinal vascular surgery - The randomised INVIPS-Trial.

AIM: While the scientific evidence in favour of negative pressure wound therapy (NPWT) dressings on sutured incisions in the prevention of surgical site infections (SSIs) has increased, the cost-effectiveness after vascular surgery has not been evaluated. The aim of this study was to evaluate the cost-effectiveness of NPWT compared to standard dressings for the prevention of SSIs after open inguinal vascular surgery. MATERIALS AND METHODS: Patient data were retrieved from the randomised INVIPS-trial's open arm, which included patients randomised to either NPWT or standard dressings. The patients were surveyed for SSIs for 90 days postoperatively. The patients' individual cost data were included and analysed from a healthcare perspective. The patients' quality of life was measured using the Vascuqol-6 questionnaire pre- and 30 days postoperatively. Cost-effectiveness of NPWT was determined by decreased or equal total costs and a significant reduction in SSI incidence. RESULTS: The mean vascular procedure-related costs at 90 days were €16,621 for patients treated with NPWT (n = 59) and €16,285 for patients treated with standard dressings (n = 60), p = 0.85. The SSI incidence in patients treated with NPWT was 11.9% (n = 7/59) compared to 30.0% (n = 18/60) with standard dressings, p = 0.015. This corresponds to an increased mean cost of €1,853 per SSI avoided. The cost-effectiveness plane of incremental vascular procedure-related costs and difference in Vascuqol-6 score showed that 42% of estimates were in the quadrant where NPWT was dominant. CONCLUSION: NPWT is considered cost-effective over standard dressings in patients undergoing open inguinal vascular surgery due to reduced SSI incidence at no higher costs.

Use of topical sevoflurane in pressure ulcer treatment in a double-lung transplant patient.

Pain caused by wounds of different etiology is usually treated with oral analgesics. New topical use of products such as the ether anesthetic sevoflurane shows good results for pain control and has additional benefits. Pressure ulcers are painful and patients may benefit from the use of sevoflurane. We present the case of a double-lung transplant patient with a long-standing sacral pressure ulcer with poor pain control, for which sevoflurane dressings were used. The number of pain-free hours after application, the amount of daily analgesics and the size of the wound were monitored with the mobile wound application MOWA. After several days of sevoflurane application, the patient reduced analgesic consumption, remained longer free of pain, and the size of the wound decreased. Unfortunately, the patient had serious complications due to multiple comorbidities and died before the wound healed completely. Topical use of sevoflurane in pressure ulcers may be a good option to treat pain and improve patient quality of life.

New Device Makes Tracheostomy Dressing Changes Easier and More Comfortable.

PURPOSE: This study compared the use of the tracheostomy dressing applicator (TDA) to the standard procedure for tracheostomy dressing changes. DESIGN: A prospective quasi-experimental study was performed. METHODS: Nineteen patients and 117 nurses answered a survey after changing the tracheostomy dressing with the TDA and using standard procedure. FINDINGS: Nurses rated the TDA easier to use in patients with average-sized necks and more favorably on observed discomfort in patients with average-sized and larger necks. Patients rated less discomfort with the TDA compared with the standard method of dressing change. CONCLUSION: The TDA is an effective device to facilitate tracheostomy dressing changes, possibly improving compliance and decreasing skin complications. CLINICAL RELEVANCE: The TDA is a useful device that can improve efficiency of dressing changes with the potential to save time and improve outcomes.

Analgesic efficacy of sufentanil in dressings after surgical treatment of burn wounds.

BACKGROUND: The aim of this study was to assess the analgesic efficacy of sufentanil in dressings after surgical treatment of burn wounds. PATIENTS AND METHODS: Twenty adult patients, who underwent surgical treatment of third-degree burn wounds under general anesthesia, were included. Two of the patients underwent surgery twice. During surgery, patients received 50-100 µg fentanyl every 20-30 min and, after surgery, patients received 100 mg ketoprofen twice daily. Additionally, ten patients (group 1) received 50 µg sufentanil added to the burn wound dressings soaked in octenidine and phenoxyethanol while 10 patients (group 2) received 25 µg sufentanil added to the same dressings. The rescue analgesic, which was administered when pain intensified, was 5 mg subcutaneous morphine. Plasma sufentanil concentrations were assayed at 1, 2, 3, and 6 h after surgery completion and when pain was reported, along with pain intensity evaluation. RESULTS: Sufentanil was not detected in the serum of any patients. Rescue morphine was given during the postoperative period (24 h) in one patient in group 1 (who underwent surgery twice) and three patients in group 2. The mean sufentanil concentration in dressings was higher in group 1 (0.13 ± 0.03) than group 2 (0.06 ± 0.03 µg/mL; p < 0.001). The group 1 patient who received rescue morphine had a sufentanil concentration of 0.10 µg/mL, which was the lowest concentration in group 1. Group 2 patients who received rescue morphine had sufentanil concentrations of at least two-fold lower (0.03-0.05 µg/mL). No adverse effects were observed. CONCLUSIONS: Sufentanil in dressings after burn wound surgery provides effective and safe analgesia and the sufentanil concentration in dressings should be ≥0.10 µg/mL in a solution of octenidine and phenoxyethanol.

Effect of Soft Silicone Foam Dressings on Intraoperatively Acquired Pressure Injuries: A Randomized Study in Patients Undergoing Spinal Surgery.

The use of prophylactic dressings to help prevent intraoperatively acquired pressure injuries (IAPIs) merits further study. PURPOSE: To examine how the use of a soft silicone foam dressing affects the development of IAPIs in patients undergoing spinal surgery to obtain baseline data supporting evidence-based nursing care. METHODS: Using a self-controlled study design, 64 patients requiring thoracic or lumbar surgery on a Wilson frame at a hospital in Seoul, South Korea, were recruited between February 12 and September 1, 2018; 50 patients were eligible. Basic demographic, health, and surgical data were obtained. Before surgery, the left or right side chest and iliac crest areas were randomly assigned to be covered with a soft silicone foam dressing. The areas were assessed at 2 time points: immediately after and 30 minutes after surgery. If an IAPI was present at 30 minutes after surgery, all sites were reevaluated after 7 days. RESULTS: The majority of participants were male (26 participants, 52%). Average patient age was 62.54 (± 13.83) years, with a body mass index of 24.32 (± 4.23) kg/m2. Average length of surgery was 218.4 (± 137) minutes. Immediately after surgery, 26 IAPIs were observed and there was a significant difference between dressed and non-dressed chest areas for the number of IAPIs (4% vs. 28%; P = .002). After 30 minutes, the total number of IAPIs was 20 and the difference between IAPIs in the iliac crest area was significant between dressed and non-dressed areas (0% vs. 14%; P = .012). After 1 week, there were no chest or iliac crest IAPIs in the areas that had been covered by a dressing; however, 8 chest (61.5%) and 4 iliac crest (30.8%) area IAPIs remained when no dressing had been applied. The majority of IAPIs were stage 1 at all assessment times. After 1 week, 1 IAPI had evolved into a stage 3 injury. CONCLUSIONS: The results of this study show that many stage 1 IAPIs do resolve over time and that use of soft silicone foam dressings during spinal surgery can significantly reduce IAPI rates. Additional longitudinal studies are needed to help guide postoperative skin assessment intervals and increase the understanding about the evolution of stage 1 IAPIs.

The safety and efficacy of Sclerosing foam on treating venous leg ulcers: Protocol for systematic review and meta-analysis.

BACKGROUND: Venous leg ulcers (VLUs) are common throughout the world, which seriously affects the patient's work and life. Relevant researches suggested that sclerosing foam (SF) has potential benefits for VLUs. However, there is no consistent conclusion. The purpose of our study is to assess whether SF is effective and safe for VLUs. METHODS: Relevant clinical randomized controlled trials will be obtained from a search of 8 databases (with no language restrictions) from their inception to May 2020: PubMed, the Cochrane Library, EMBASE, Web of Science, China National Knowledge Infrastructure Database, Wanfang Database, China Science and Technology Journal Database, and Chinese Biological Medicine. Data will be analyzed using RevMan 5.3 after literature screening and data extraction according to predefined inclusion and exclusion criteria. Cochrane Collaboration Risk of bias Tool will be applied in evaluating the quality of enrolled articles. The primary outcome is Closure of venous leg ulcers, ulcer healing rate, adverse events related to SF. The secondary outcomes include ulcer healing time, ulcer recurrence rate, pain. Risk ratio will be used for categorical data; mean differences will be used for measurement data. Where possible and appropriate, meta-analysis will be performed for each outcome. RESULTS: To clarify whether Sclerosing foam can be safe and efficient on treating venous leg ulcers. CONCLUSION: Our review will provide useful information to judge whether Sclerosing Foam is an effective and safe intervention for patients with venous leg ulcers.

The Estimation of Blood Paramagnetic Center Changes during Burns Management with Biodegradable Propolis-Nanofiber Dressing.

The evolution of the paramagnetic center system in blood during the healing of skin burn wounds dressed with a biodegradable apitherapeutic nanofiber dressing was examined. The aim of this study was to determine the changes in paramagnetic centers in blood during the influence of apitherapeutic nanofiber dressings on the healing process. The blood samples were tested before burn infliction (day 0) and, respectively, on the 10th and 21st days of the experiment. Paramagnetic centers in the blood of the pig used as the model animal were examined with an X-band (9.3 GHz) electron paramagnetic resonance spectroscopy. The EPR spectra were measured with Bruker spectrometer at 230 K with a modulation frequency of 100 kHz. The EPR lines of the high spin Fe3+ in methemoglobin, high spin Fe3+ in transferrin, Cu2+ in ceruloplasmin, and free radicals were observed in the multicomponent spectra of blood. For the application of the apitherapeutic nanofiber dressing, the amplitudes of the EPR signals of Fe3+ in methemoglobin were similar up to 10 days. For the experiment with the apitherapeutic formulation, the heights of EPR signals of Fe3+ in transferrin were lower after 10 days and 21 days of therapy, compared to day 0. For the application of the apitherapeutic formulation the signals of Cu2+ in ceruloplasmin and free radicals, strongly decreased after 10 days of therapy, and after 21 days it increased to the initial values characteristic for day 0. The apitherapeutic formulation caused that after 21 days the EPR spectrum of Cu2+ in ceruloplasmin and free radicals was considerably high. The apitherapeutic formulation interaction after 10 days and after 21 days of therapy resulted in the low EPR lines of Fe3+ in methemoglobin. EPR spectra of blood may be useful for presentation of the changes in its paramagnetic centers during the healing process of the burn wounds.

Chlorhexidine-impregnated sponge versus chlorhexidine gel dressing for short-term intravascular catheters: which one is better?

BACKGROUND: Chlorhexidine-gluconate (CHG) impregnated dressings may prevent catheter-related bloodstream infections (CRBSI). Chlorhexidine-impregnated sponge dressings (sponge-dress) and gel dressings (gel-dress) have never been directly compared. We used the data collected for two randomized-controlled trials to perform a comparison between sponge-dress and gel-dress. METHODS: Adult critically ill patients who required short-term central venous or arterial catheter insertion were recruited. Our main analysis included only patients with CHG-impregnated dressings. The effect of gel-dress (versus sponge-dress) on major catheter-related infections (MCRI) and CRBSI was estimated using multivariate marginal Cox models. The comparative risks of dressing disruption and contact dermatitis were evaluated using logistic mix models for clustered data. An explanatory analysis compared gel-dress with standard dressings using either CHG skin disinfection or povidone iodine skin disinfection. RESULTS: A total of 3483 patients and 7941 catheters were observed in 16 intensive care units. Sponge-dress and gel-dress were utilized for 1953 and 2108 catheters, respectively. After adjustment for confounders, gel-dress showed similar risk for MCRI compared to sponge-dress (HR 0.80, 95% CI 0.28-2.31, p = 0.68) and CRBSI (HR 1.13, 95% CI 0.34-3.70, p = 0.85), less dressing disruptions (OR 0.72, 95% CI 0.60-0.86, p < 0.001), and more contact dermatitis (OR 3.60, 95% CI 2.51-5.15, p < 0.01). However, gel-dress increased the risk of contact dermatitis only if CHG was used for skin antisepsis (OR 1.94, 95% CI 1.38-2.71, p < 0.01). CONCLUSIONS: We described a similar infection risk for gel-dress and sponge-dress. Gel-dress showed fewer dressing disruptions. Concomitant use of CHG for skin disinfection and CHG-impregnated dressing may significantly increase contact dermatitis. TRIALS REGISTRATION: These studies were registered within ClinicalTrials.gov (numbers NCT01189682 and NCT00417235 ).

Prevención de úlcereas por presión en neonatos con ventilación mecánica no invasiva / Prevention of pressure ulcers in neonates with non-invasive mechanical ventilation

OBJETIVO: Determinar el apósito con mayor efectividad (hidrocoloide o espuma de poliuretano) en neonatos ingresados en las unidades de cuidados intensivos neonatal y pediátrica del Hospital Clínico Universitario de Valencia, sometidos a ventilación mecánica no invasiva para la prevención de úlceras por presión nasales y/o faciales. MATERIAL Y MÉTODOS: Proyecto de investigación de tipo observacional, prospectivo y analítico cuya muestra estaba formada por 13 neonatos con ventilación mecánica no invasiva, hospitalizados en la unidad de cuidados intensivos neonatales y pediátrica. Los neonatos fueron divididos en dos grupos: en el grupo A (7 pacientes) se empleó el apósito de espuma de poliuretano y en el grupo B se utilizó el hidrocoloide (6 pacientes). La recogida de datos se realizó durante el período comprendido entre abril y mayo de 2018. RESULTADOS: De los neonatos incluidos en el estudio, 5 (38,5%) presentaron úlceras por presión nasales; el resto (62%) no presentó úlceras. Además, se obtuvo que, del total de pacientes con lesión, un 60% llevaba el apósito hidrocoloide y un 40% el de espuma de poliuretano. CONCLUSIONES: Tras el estudio, se determinó que el apósito de espuma de poliuretano presentaba un menor porcentaje de aparición de UPP en comparación con el hidrocoloide. Sin embargo, sería recomendable valorar la posibilidad de emplear alguno de ellos como medida de protección

OBJECTIVE: To determine the most effective dressing (hydrocolloid or polyurethane foam) in neonates admitted by the Neonatal and Pediatric Intensive Care Unit of the Hospital Clínico Universitario de Valencia, subjected to non-invasive mechanical ventilation for the prevention of pressure ulcers nasal and/or facial. MATERIAL AND METHODS: observational, prospective and analytical research project whose sample considered of 13 neonates with non-invasive mechanical ventilation hospitalized in the Neonatal and Pediatric Intensive Care Unit. They were divided into two groups, where group A (7 patients) used the polyurethane foam dressing and group B used the hydrocolloid dressing (6 patients). The data collection was carried out during the period from April to May 2018. RESULTS: Of the neonates included in the study, 5 presented nasal pressure ulcers (38.5%) and the rest did not (62%). In addition, it was obtained that, of the total of patients with injury, 60% wore the hydrocolloid dressing and 40% that of polyurethane foam. CONCLUSIONS: After the study, it was determined that the polyurethane foam dressing had a lower percentage of appearance of pressure ulcers compared to the hydrocolloid. However, it would be advisable to appraise the possibility of using any of them as a protection measure

Negative Pressure Wound Therapy Compared to Petrolatum Gauze and a Bogota Bag to Manage Postoperative Midline Abdominal Wound Dehiscence: A Pilot, Nonrandomized Controlled Trial.

Treating postoperative abdominal wound dehiscence following abdominal surgery using negative pressure wound therapy (NPWT) has shown promising results. PURPOSE: A study was conducted to evaluate the efficacy of NPWT for fascial closure/cutaneous cover compared to non-NPWT treatment using petrolatum gauze and a Bogota bag in patients with postoperative laparotomy wound dehiscence. METHODS: A single center, prospective, nonrandomized pilot study was conducted. Using convenience sampling methods, consecutive patients on 6 different surgical units who were at least 18 years of age and who developed postoperative abdominal wound dehiscence following elective and emergency laparotomy from January 2017 to December 2018 were recruited. NPWT dressing with polyvinyl white foam sponge or loosely packed, saline-soaked petrolatum gauze followed by Bogota bag application were used and compared. Baseline patient demographics and history were collected, and patients were followed for an average of 6 months after surgery. Number of days until first signs of granulation tissue appearance, time until complete granulation tissue cover/fascial surgical closure, and hospital discharge were compared. Categorical variables (gender, comorbidities, presence or absence of stoma, exposure to prior radiotherapy) were expressed as proportions and analyzed using chi-squared test or Fischer's exact test. Continuous variables such as age, body mass index, albumin, postoperative hospital stay, and number of days required for decision for fascial closure were expressed as Mean ± standard deviation and analyzed using an independent t test or Mann Whitney U test based on whether the data followed normal distribution. Postoperative day of wound dehiscence, the number of days for the appearance of granulation tissue, and the number of NPWT placements required also were assessed using Mean ± standard deviation and analyzed using an independent t test. A P value <.05 was considered significant. RESULTS: Sixty (60) patients were included, but 4 in NPWT group and 10 in the non-NPWT group could not complete the study, leaving 26 patients in NPWT group and 20 patients in non-NPWT group. Demographic and surgical variables were not significantly different. Patients in both groups achieved complete wound coverage by surgical closure or healing by secondary intention. Days until first signs of granulation tissue (2.92 vs. 6.65; P <.001), number of days until fascial closure (15.50 vs. 29.50; P <.001), and length of postoperative hospital stay (24.30 vs. 37.90; P <.001) were significantly less in NPWT group. Two (2) patients (7.6%) in the NPWT developed a fistula during the 6-month follow-up period. No fistulas developed in the control group, and no intra-abdominal abscesses, ventral hernias, or wound dehiscence were reported in either group. CONCLUSION: Time until first signs of granulation tissue appearance and complete granulation tissue coverage was significantly shorter in the NPWT group, but time until definitive closure was not evaluated. Randomized, controlled clinical studies to compare definitive time to wound closure and long-term follow up to evaluate long-term complication rates, including the risk of developing fistulas, are warranted.

Effects of Hydrogel With Enriched Sodium Alginate in Wounds of Diabetic Patients.

Objective of this study was to evaluate the efficacy of the autolytic debridement promoted by hydrogel with sodium alginate enriched with fatty acids and vitamins A and E in the healing of foot wounds in diabetic patients. A clinical study was conducted at an outpatient clinic of medical specialties. The sample comprised 8 patients supervised for a 3-month period, from April to July 2017, by means of a clinical history, photographic record, planimetry, and classification of the wound severity by the Pressure Ulcer Scale for Healing (PUSH) system. Of the 8 patients supervised, 1 dropped out and 7 were followed up for 12 weeks. Only 2 had complete wound healing, but all presented a reduction of the lesion area of approximately 22.2% and PUSH score of 9.8 to 6.6. This study found that hydrogel showed good results for the treatment of diabetic feet, reducing the area and overall PUSH score of the wounds.
